The invention relates to a combination of bottle and cap for dispensing a liquid. The bottle includes a narrow neck and a hollow handle. The hollow interior of the handle communicates at its upper and lower end with the interior of the body, to permit a flow of air through the neck opening, via the interior of the handle, to a lower region within the interior of the container so as to minimize glugging during pouring. The cap comprises a cap body attachable to the neck of the bottle. The cap includes on its crown first and second openings, for dispensing liquid and intake of air, respectively. The cap is configured to attach to the container body so as to position the second opening generally facing the handle, while the first opening is opposed to the handle. During pouring, air flows into the second opening within the cap as liquid exits the first opening, with the inflowing air being channeled into the hollow handle interior with minimal interference with the outflowing liquid so as to introduce air into the interior of the body to displace the liquid being poured from the bottle.

A robot has a track assembly having tracks configured to move the robot in a first direction and a wheel assembly having wheels configured to move the robot in a second direction orthogonal to the first direction. A toggling assembly switches between the track assembly and the wheel assembly. The robot modules can mate with each other. The robot module has an elongated shaft with a head and a narrow neck. The shaft extends outward from the side of the robot module. A mating robot module has a clamping mechanism with opposing clamps which in an opened position receive the shaft. In a closed position, the clamps define an opening which matches and engages the cross-section of the neck of the elongated shaft. The clamping mechanism has a drive mode to drive the module, a clamping mode for docking, and neutral mode for alignment prior to clamping.

A battery operated, handheld fluid dispenser comprises a supply container having a body portion and a narrow neck extending upwardly therefrom. A pump and discharge unit is mounted on the upper end of the neck and comprises a pump diaphragm and pump chamber for pumping liquid from the container to a discharge nozzle. A battery powered pump drive unit is mounted on the container and comprises an electric motor having an output shaft coupled with the pump diaphragm through a cam and cam follower arrangement to displace the diaphragm through a pump stroke when the motor is energized. The cam is rotatably driven by the motor, and the cam follower is attached to the diaphragm, whereby rotation of said cam axially displaces the diaphragm, and the cam and cam follower have interengaging dual cam faces for balancing lateral forces therebetween during rotation of said cam relative to said cam follower.

The handhold of an exercise handgrip turns freely while seated between the open ends of the upwardly extending prongs. It can be easily removed by moving the specially formed end part of the handhold into an access opening wide enough to slip the end part through. In positioning the handhold's end part for this removal, it must be forcibly snapped through a narrow opening. By reversing the procedure, the handhold can easily be returned to its place of rotation. The specially formed end part of the handhold must, therefore, have a narrow neck-like portion to fit through the narrow opening but the end part must also be enlarged to keep it in place for rotation. Preferably, there is also a stem and ball unit in one of the prongs which swings into place to trap exercise sheeting, cord or other media within an opening at the handgrip's bottom portion.

The present disclosure relates to improved magnetic mixing assemblies and mixing system. The magnetic mixing assemblies can provide improved mixing action, ease of use, and low friction. The mixing assemblies can be adapted for use with a wide variety of containers including narrower neck containers and flexible containers.

A housing for a thin active probe has two identical molded housing-halves that when assembled form a cavity that encloses the chassis upon which is carried the active circuitry of the probe. The parts exhibit complementary self-symmetry about a longitudinal axis, such that when one is rotated about that axis it performs the mating functions needed to interlock with another part representing its un-rotated self. Interlocking is accomplished by circular tabs and sockets that interfere and prevent the parts from separating once the tabs are in the sockets. The circular tabs are joined to the balance of the housing-half that carries them by a narrow neck and can be sprung over the other housing-half to return to their natural position and fit into a circular socket in that other housing-half. A tapered edge or ramp portion on the underside of each circular tab allows it to automatically spring out of the way as the two parts are moved toward each other in a direction generally perpendicular to the longitudinal axis of the parts. Each circular socket contains a stop that prevent its tab from completely passing through the socket. Each housing-half has a straight tab between its circular tabs that enter an interior recess on the other housing-half to support its circular sockets as they receive their tabs. Each housing-half contains in a front surface an entire aperture for a detachable probe lead, and each contains in a rear surface at least one half-aperture that, when the two housing-halves are joined, forms a larger aperture whose perimeter engages a corresponding groove in a strain relief for a cable. The exterior surface of the mated housing-halves has, on each side through which runs the line of the mating edges, a flat shallow recess. The interlocking circular tabs and sockets are located within the extent of this shallow recess, which can receive an adhesive label that may conceal and stiffen the interlocking circular tabs and sockets.

A tool holding and displaying device includes a plate having a narrower neck portion formed between an upper orifice and a lower aperture. The upper orifice of the plate includes an inner diameter greater than that of the lower aperture of the plate, and a bracket includes a latch having an enlarged head formed on a pin for engaging into the upper orifice of the plate. The enlarged head of the latch is greater than the lower apertures of the plate, to engage with the plate, and to anchor the bracket to the plate. The plate includes one or more spring arms to engage with the pin of the latch of the bracket, to lock the latch of the bracket to the plate.

A seal for a regenerative air preheater. The seal is comprised of two members that each have a plurality of tabs and slots. The tabs and slots interlock so that the tabs on one member are positioned adjacent the slots on the other member. The tabs have a narrow neck section and a wider sealing section. The wider sealing sections overlay and the narrow neck sections are positioned within a recessed region of the notch on the opposite member so as to interlock the two members. The seal is mounted either to the rotor or to the inner wall of the housing so as to extend through the bypass gap between the rotor and the inner wall of the housing. As the tabs are flexible, the tabs may resiliently deform as a result of the tabs making contact with the sealing surface of the heat exchanger. The air preheater further comprises a reinforcing section that stabilizes the tabs when the tabs resiliently deform.
