Abstract: An ophthalmological device comprises an implant member carrying an antifibrotic agent that is released slowly over a prolonged period when inserted into a wound in an eye produced by surgery. The member is placed in the vicinity of a wound created during the surgery to inhibit inflammatory cell proliferation, thereby preventing the growth of fibrous tissue after the eye surgery.

Abstract: A book spread identification arrangement for a board book is provided, the arrangement comprising a plurality of conductive paths, contact means disposed adjacent at least part of at least one of the conductive paths and processing means connected to the conductive paths and configured for processing signals associated with the conductive paths. One selection end of each path is disposed adjacent the spine surface of the book. The contact means comprise one or more conductive surfaces and are arranged, upon opening of the book to a spread, to contact one of a plurality of combinations of one or more of the conductive paths. Each of the plurality of combinations is in a predetermined unique association with a respective single spread of the book. From the processed signals, the processing means are able to determine the particular combination of conductive paths contacted by the contact means and identify to which spread the book is open.

Abstract: A golf club head cover comprises a pair of complementary cover sections connected to pivot about a manually actuated spring-biased clip member normally biases the cover sections into a closed condition. The clip member includes a pair of handle elements to be gripped between the thumb and one or more fingers by a user and depressed towards each other to move the cover sections so they pivot and spread apart into an open condition. When the head of a golf club is between the spread apart cover sections in the open condition, or is withdrawn, the user releases the grip on the handle elements so the cover sections come together automatically into the closed condition.

Abstract: A door having a pneumatic sensing edge is operated automatically to open when an object and the edge make contact An optical pressure switch (10) in fluid communication with gas forced from the edge on contact with the object initiates the operation of a door opener The optical pressure switch (10) includes a membrane (16) having a portion that interrupts a light beam (LB) when the membrane (16) flexes due to the increase gas pressure over ambient pressure as gas is forced from the edge.

Abstract: An air-conditioning system operable at different states employs a control unit including a receiver and a transmitter. The receiver is connected electrically to a switching device for a compressor of the air-conditioning system. The compressor is installed at a remote location exterior to a building. The receiver is responsive to an encoded radio signal to provide an electronic control signal for actuating the switching device. The transmitter is installed within the building and is electrically connected to a thermostat within the building that responds to temperature changes to provide a temperature control signal. The transmitter upon receipt of the temperature control signal transmits to the remote location the encoded radio signal for operating the air-conditioning system at one of the different states.

Abstract: A pulley removal system used to remove a pulley attached to an internal combustion engine includes a plurality of puller jaw members adapted to be detachably and radially connected to a hub member. Each jaw member comprises an elongated body having a top surface, an underside surface, and first and second opposed ends. The first end is adapted to be attached to the hub member, and the second end has hooked tip free to grasp a flange of a pulley. The hooked tip has a terminal edge with predetermined dimensions that enable it to fit within different sized recesses in the flange of the different pulleys and an underside arcuate surface extending from the terminal edge and merging with the underside surface to form a bite that receives the flange when the terminal end fits within the recess in the flange.

Abstract: A tool removes from, or inserts into, an arm of a wheel mounting for an automotive vehicle a bushing. The tool includes a press member configured to grip the arm while overlying the location in the arm for the bushing. A screw element passes through a portion of the press member and engages a pressing cup with an outer rim that abuts an end of the bushing as the screw is manually rotated. The press member, screw element, and pressing cup upon being aligned and assembled with the press member gripping the arm and the rim of the pressing cup bearing against the end of the bushing, the screw element is rotated to apply a force to the end of the bushing as the screw element advances in the direction of the arm.
