An assembly for occluding a vascular site (e.g., an aneurysm) of a human or veterinary patient includes a vaso-occlusive member, a pusher member having a distal end and a severable junction located proximal to the distal end, and a pivotable coupling that couples the pusher member to the occlusive member. A delivery catheter can be used to deliver the vaso-occlusive member to the vascular site. A method of using the assembly to occlude an aneurysm having an aneurysmal sac and an aneurysmal neck, comprises locating the catheter within the aneurysmal neck, and manipulating the pusher member to place the vaso-occlusive member within the aneurysmal sac. The method further comprises severing the severable junction to detach the vaso-occlusive member from the pusher member. As a result, an axial force is applied by the vaso-occlusive member in a proximal direction, which buckles the pivotable coupling to laterally deflect the axial force. The lateral deflection of the axial force caused by the buckling of the pivotable coupling prevents the catheter from being displaced from the aneurysmal neck by the axial force.

A multi-component connection system suitable for automobiles includes a female clip member having a slot, and a male clip member having a male element insertable within the slot. The slot and male element include mutually engageable cooperative structures. A shank connected to the male element includes wings mounted at a distal end and capable of resilient lateral deflection relative to the longitudinal axis of the shank. The female clip member may be affixed to a first component and the male clip member may be insertable within a hole in a second component so as to connect the two components when the male clip member is inserted in the hole, the male element is disposed within the slot, and the cooperative structures are engaged.

A motor vehicle headlight comprising a light source, a reflector and a cover lens. The reflector generates a pre-formed light beam such that its modification by any optical elements on the cover lens is unnecessary. The cover lens receives, from at least a substantial part of the reflector, radiation having a mean angle of incidence in a horizontal plane which varies progressively with horizontal displacement over the cover lens. The cover lens includes a set of striations for lateral deflection of the light, with each striation having an individual angular distribution law which is determined by the orientation of the light from the reflector and by the lateral spreading characteristic of the striation. The spreading characteristics of the striations are determined in such a way that the aggregate angular distribution law of the different striations has a curve which is essentially flat.

A gondola car has a body for lading carried on an underframe. The underframe includes a center sill and cross-bearers. The car has deep side beams having top chords, side sills, and side sheets. The lower portion of the car includes tubs that seat between the cross-bearers. The car may have an internal volume of more than 8000 cu. ft. The car may have rotary dump claw sockets. The car has opposed internal and external stiffeners aligned at the longitudinal stations of the cross-bearers. The internal stiffeners may be triangular cantilevers extending upwardly inside the side sheets. The side sheet lies intermediate the stiffeners and their flanges. The top chords may be wider in cross-section than the side sills. The side sills may define torque tubes that co-operate with the sidewall stiffeners and the top chords to resist lateral deflection. The car may include a false deck, or dog-house at one end to accommodate the brake reservoir and brake valve, such that the car is longitudinally asymmetric.

An apparatus and method is provided for lateral contact loading of an implantable transducer relative to an auditory component. The apparatus may include a contact tip for directly contacting a lateral aspect of an auditory component, and a vibratory actuator adapted for axial displacement in response to the operation of an interconnected implantable hearing aid transducer. At least a portion of the vibratory actuator may be deflectable, wherein the contact tip is laterally displaceable upon lateral deflection of the vibratory actuator to apply a lateral loading force to an auditory component. In operation, the contact tip may be positioned to apply the lateral loading force upon initial placement and then automatically moved to maintain contact with the auditory component by virtue of deflection of the vibratory actuator, (e.g., responsive) post-implantation auditory component movement.

The invention discloses a method for lateral control of an unmanned aerial vehicle, which belongs to the field of the control of the unmanned aerial vehicle flight. In the method, the input lateral posture control volume gamma (g) of a lateral posture control loop is calculated according to the lateral deflection distance Sg, the lateral migration velocity and the distance to go Dtogo of an unmanned aerial vehicle, so as to guide the unmanned aerial vehicle to fly along an expected airliner. The invention fully considers aircraft performances and actual flight conditions to dynamically determine the limit amplitude of the lateral migration speed, so as to achieve the high-quality transition for correction of the actual flight path; and the flying velocity vector of the aircraft changes along the shorter path to the direction of the expected airline during the switching of the flight segment of the aircraft, thereby avoiding the unnecessary cross in the flight path, shortening the airline flight path, and improving the flight performance.

A coiling arrangement for a continuous composite sucker rod for a well sump includes a spool having a substantially cylindrical shape. A support structure rotatably supporting the spool about a rotation shaft, and for translatory movement. A guide arrangement moves the spool reciprocally such that the reciprocal motion of the support structure is along a direction that is parallel to the axis of rotation of the shaft. The rod is thereby accumulated on the spool in a spiral manner with minimal lateral deflection. In one form the spool is reciprocal relative to its support shaft. In another a support structure is reciprocal with the spool.

The invention discloses a transmission device and an air conditioner comprising the transmission device. The transmission device comprises a first connecting rod, a second connecting rod, air guiding blades and a horizontal transmission mechanism. A second sliding part of the second connecting rod is slidably connected with a first sliding part of the first connecting rod, and the horizontal transmission mechanism drives the air guiding blades connected to the second connecting rod to perform lateral deflection through the first connecting rod. When the air guiding blades perform longitudinal movement up and down in air outlet, the air guiding blades are adjusted to the appropriate position according to a running mode of the air conditioner so as to overcome influence on wind direction adjustment caused by adjustment of density difference between air flow and indoor air. Simultaneously, when left and right swing is not needed, the air guiding blades can all descend into an air conditioner base below the air outlet to be hidden; simultaneously, when swing is not needed, the air guiding blades can move downwards until the air guiding blades are hidden; the air conditioner is intelligently controlled to supply air in a three-dimensional mode through the transmission device, manual poking is not needed, and accidents in the operation process are avoided.

Disclosed are mounting means for agricultural tools, for example tillage assemblies, that comprise a resilient element and a horizontal pivot axis. This allows upward and rearward deflection of a tillage blade of the assembly in response to impact with obstacles. Tillage implements comprising the foregoing assemblies are also disclosed. In certain embodiments, the assemblies advantageously allow lateral deflection of at least a support arm of the assembly in response to impact with obstacles, which may be enhanced by providing a pivot means of the assembly with a resilient bushing. The resilient element and/or the resilient bushing may comprise elastomeric materials.

A mostly transparent billiard ball particularly useful as a training cue ball is disclosed. The ball includes an inner core centered within a sufficiently transparent spherical outer covering that provides an optimum zone, visible to the player, at which he or she can aim the tip of a cue stick. This inner zone is especially serviceable to restrict a player's aim when striking the ball off-center in order to effectively impart sidespin while limiting lateral deflection to the ball. The inner zone may also simply assist the player to determine the ball's exact center when striking the ball in order to accurately impart no sidespin. In either case, cueing technique is enhanced and the player practices with consistency. The centered inner core also provides enough mass to bring the training ball to within an acceptable weight range for casual and professional levels of play.

A textured sheet of ductile material with self-locking barbs extending from a face of the sheet of ductile material. Each self-locking barb is curved so that one side is convex and an opposite side is concave, and a thrust line perpendicular to the face of the sheet lies entirely within each self-locking barb. When a barb is pressed into a substrate, the barb deflects while the barb penetrates into the substrate so that textured sheet is bound to the substrate with a portion of the substrate material above a portion of the barb, providing pull-out resistance. Laminates formed with such textured sheets and methods of producing same are also provided, including a method of pressing the textured sheet into a substrate while the sheet is curved away from the substrate, resulting in fan-out of the barbs and lateral deflection forces on the barbs as they penetrate the substrate.

A method and apparatus for laterally deflecting and/or separating a flow of particles using a static array of optical tweezers. In an array of optical tweezers with a lattice constant larger than the size of a particle of interest, particles driven past the array by an external force experience an additional interaction with the array of traps. By altering the angle of the array of traps relative to the external force, the particles' movement from trap to trap inside the array can be biased away from the direction of the external force, thereby enabling selective deflection and/or separation of particles.
