18569 results about "Reciprocating motion" patented technology

Reciprocating motion, also called reciprocation, is a repetitive up-and-down or back-and-forth linear motion. It is found in a wide range of mechanisms, including reciprocating engines and pumps. The two opposite motions that comprise a single reciprocation cycle are called strokes.

Powered cutting surface with protective guard for equine teeth

An arrangement that may be used in combination with selected tools having a tooth cutting surface for the care and maintenance such as removing a selected portion of the exposed surface of equine teeth. The selected tool in communication with a source of powered motion and mounted in and supported by a hand piece which is guided into the mouth of the horse. The cutting surface of the powered tool is partially guarded so as to protect fleshy portions of the horse's mouth from being engaged by the cutting surface. The hand piece provides for quick on and off attachment of a selected cutting surface for maintenance of a preselected portion of teeth within the same hand piece or another hand piece sized to ease access to the next selected portion of the horse's mouth. The selected hand piece arrangement may further incorporate a vacuum channel whereby the tooth dust and debris created by the powered cutting surface removing a portion of tooth is sucked out of the mouth of the horse. The motion of the tooth surface removal tool may be changed from rotary to powered reciprocating motion for a selected portion of the teeth or changed to be at a preselected angle. Attaching the powered drive to the rotary cutting surface by means of an adjustable clutch further enhances protection from injury to the inside of the mouth of the horse.

Method and apparatus for selective engagement of shelf divider structures within a shelf management system

Apparatus and method for selectively engaging and securing an array of shelf dividers to a mounting device which is securable to a display shelf. In the first form a divider is characterized by a divider structure having an elongated vertical wall and elongated horizontal base that operates to divide, organize and support the displayed merchandise. A resilient latch located on the underside of the base of the divider structure selectively engages and secures the divider structure onto a mounting device comprising a receiving member running longitudinally along the length of the surface of the mounting device which is securable along the front edge of a display shelf. The latch and the receiving member each comprise reciprocating (i.e. complementary) protrusions to allow the cooperative engagement of the divider structure and mounting device, thus locking the divider member to and unlocking the divider member from the mounting device to permit the repositioning of the display as desired without necessitating removal of the merchandise from the display. In addition when the divider structure and mounting device are fully engaged, a second protrusion on the underside of the divider member cooperates with a flange or lip on the mounting device to prevent lateral movement of the divider structure and maintain the position of the divider perpendicular to the mounting device and the front edge of the shelf. In a second embodiment, the divider structure comprises a pusher track and a spring urged pusher assembly to automatically push merchandise to the front of the shelf. Another embodiment comprises a divider base without a vertical divider wall, and with or without a pusher track and spring urged pusher assembly, thus pushers and dividers can be used in various convenient combinations within a shelf management system.

Electronic variable stroke device and system for remote control and interactive play

InactiveUS20040082831A1Significant variabilityConvenient and relaxing environmentNon-surgical orthopedic devicesGenitals massageControl signalNetwork connection
An electronic variable stroke device comprise a base portion containing a motor-driven screw shaft, an upper portion extending from the base portion having the screw shaft extending longitudinally therein, a traveler engaged with the screw shaft to drive a part of the upper body in reciprocating longitudinal motion, and electronic controls include a transmitter/receiver for sending and receiving control signals for operating the device. A remote controller unit is provided for ergonomic operation of the device by the user. A network connection unit is provided to connect the user's device to an external service offered on the Internet or other networks, and includes controls for transmitting audio/visual content in conjunction with operation of the device. The device may be adapted as a female toy, and can exchange control signals with one or more other users operating a male toy or other electronic stimulation device. The Internet service can join a user in an interactive session with another user, or with a group of users, and even non-participating spectators. The Internet service preferably has a 3-tier structure of administrator site, host site, and affiliated play host site for efficiently handling verification of user identity and payment method, widespread offerings of user interest communities and interactive services, and distribution of revenues from customer usage to service partners. Purchasers of a network connection unit can be required to register with a warranty/registration site, to which the administrator site has access to validate a user's identity and payment method. Other applications for the Internet-based system for multi-user interactive sessions include remote game-playing and virtual videoconferencing.

Electrosurgical systems and methods for removing and modifying tissue

InactiveUS7824398B2Thermal damage is minimizedCannulasEnemata/irrigatorsEngineeringNon targeted
The present invention provides systems, apparatus and methods for selectively applying electrical energy to body tissue in order to, ablate, contract, coagulate, or otherwise modify a tissue or organ of a patient. An electrosurgical apparatus includes an electrode support bearing an active electrode in the form of a plasma blade or hook having an active edge and first and second blade sides. The active edge is adapted for severing a target tissue via localized molecular dissociation of tissue components. The first and second blade sides are adapted for engaging against, and coagulating, the severed tissue. s. A method of the present invention comprises positioning an electrosurgical probe adjacent to the target tissue so that a blade- or hook-like active electrode is brought into at least close proximity to the target tissue in the presence of an electrically conductive fluid. A high frequency voltage is applied between the active electrode and a return electrode to effect cool ablation or other modification of the target tissue. During application of the high frequency voltage, the electrosurgical apparatus may be translated, reciprocated, or otherwise manipulated such that the active edge is moved with respect to the tissue. The present invention volumetrically ablates or otherwise modifies the target tissue with minimal or no damage to surrounding, non-target tissue.

Labor reduction type agricultural chemical spraying system having automatic hose winding and unwinding apparatus

The present invention relates to a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus by which one worker is capable of spraying agricultural chemicals in such a manner that a hose is automatically wound and unwound from a reel based on a remotely controlled motor. The labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus comprises a frame in which a motored sprayer connected with an engine is installed; a reel rotatably installed in the frame wherein a hose is wound onto the reel; a first driving motor driven in both directions for rotating the reel in normal and reverse directions in accordance with a remote control signal; a rotary shaft rotating by a driving force from the rotary shaft of the reel and reciprocating a movable piece engaged to an upper side in the left and right directions with respect to the reel; a second driving motor installed on the movable piece in cooperation with the first driving motor and driven in the normal and reverse directions in accordance with a remote control signal; and a pair of rollers that are installed in the movable piece and are rotatably connected with the second driving motor and tension an outer surface of the hose, and unwind the hose from the reel.
