Abstract: A U-shaped channel is mounted on the elevator car. A solid vane is mounted on the shaft wall near each floor. As the car approaches each floor the vane passes between the walls of the U-shaped column. A plurality of photo transmitter-receivers are mounted on the channel. The receivers on one wall and the transmitters on the opposite wall. As the vane passes between the walls, it obscures or occludes the light from the transmitters and the receivers are successively turned on and off in an arrangement indicative of the distance to the floor level.

Abstract: Apparatus for splicing ends of a sheave insert material in which the ends of a premeasured length of an elastic, thermoset sheave insert material are laminated together in a special splicing jig for fabricating a unitized insert loop, which is subsequently stretched around a sheave into a preformed insert receiving slot along the circumference thereof. The jig holds the ends of the premeasured length of insert material in alignment as a heated mold, included therein, fits snugly around the ends and applies heat to the joint therebetween, into which the insert material, in liquid form, has been inserted to join the ends. The heat thus applied to the joint accelerates the curing of the liquid into the same consistency as the insert; thereby producing a unitized bond between the ends by which the unitized loop is thus formed.

Abstract: An apparatus that provides a fluid seal between a battery post and battery cover. A first stuffing box is located around the battery post. This stuffing box contains an O-ring and a gland fitting which is screwed into the stuffing box for the purpose of squeezing the O-ring to create a fluid seal relationship between the stuffing box and the battery post. A second stuffing box is formed integrally with the battery case. This stuffing box is concentric with the first stuffing box. An O-ring is provided to create a fluid seal between the two stuffing boxes. Movement of the battery post with respect to the battery case is accommodated by movement between the two stuffing boxes.

Abstract: A permanent magnet motor is provided which has first and second U-shaped sections comprising the motor stator. Each section is constructed of low reluctance magnetic material. The motor armature shaft passes through a hole in the bight of each section and carries a commutator. An air space separates the bight and shaft to provide a high reluctance path to the shaft. The two parallel sides of the first section fit between the two sides of the second section in a contact relation; the combination defining a two piece magnetic circuit that passes around the motor from end to end. The first section contains a permanent magnet mounted upon each of the sides at diametrically opposite locations adjacent the armature. The flux coupling the two magnets passes through the armature core. The magnets define a pole pair and are spaced very close to the edge of the armature core to minimize the air gap between the armature and the magnet.

Abstract: Ignition pulses are supplied to an internal combustion engine from a breakerless electronic ignition system wherein the ignition pulses are produced in response to the movement of teeth on an electrically conductive trigger wheel past an inductive sensor. The inductive sensor is part of a LC tank circuit of an oscillator normally producing an oscillatory output signal which is detected by a bistable demodulator, and as a tooth moves into close proximity with the inductive sensor energy from the tank circuit is lost through an inductive coupling with the trigger wheel until the oscillatory output signal is terminated. The bistable demodulator responds to the absence of an oscillatory output signal by producing a timing signal which causes an ignition pulse to be supplied to the engine. The trigger wheel rotates in synchronization with the engine, and the initial timing of the ignition system is determined by setting the relative positions of the sensor and the trigger wheel.

Abstract: A brush cage for an electric motor wherein the brush sets are mounted on two assemblies. One assembly is mounted to the frame and the second assembly is mounted to a removable frame end plate, which when removed, provides access to the first assembly and commutator. Each assembly includes an electrically conductive ring upon which the brushes are mounted. The brushes are electrically interconnected through the ring upon which they are mounted. The rings are in a spaced relation to each other along the commutator rotational axis and are on substantially parallel planes which are perpendicular to that axis. The brushes on one ring fit between the brushes on the other ring so as to be disposed around the commutator in an inter-leafed pattern within the space between the two rings.

Abstract: A photocomposing machine having a cassette containing a continuous film tape loop. The loop rides on two rollers which stretch the loop when it is inserted on the photocomposing machine. The rollers are spool-shaped to avoid contact with the character containing portions of the tape. A lead plate, which is integral with the cassette, provides proper loop alignment and tension. The illuminating light from the photocomposing machine is directed through the tape and out of the cassette by means of a prism system that extends through the bottom of the cassette. The loop contains character identification and alignment markings which are illuminated through corresponding apertures in the lead plate.

Abstract: A container for a pressure gauge movement which employs a viewing window. The container includes a flange along the edge adjacent to the window which receives the window and a resilient window sealing gasket. A resilient collar is placed around the edge of the window which sandwiches the gasket between the window and flange as it retracts. The collar includes a split and two non-parallel surfaces. The split allows the collar to be expanded when placed around the flange and window. The surfaces define a groove to receive the edges and press the flange and window together around the gasket as the collar retracts. A ring is placed over the collar which contains a plurality of detents and a window contacting surface. The detents engage the collar and cause it to contract and also lock the ring and collar in place on the case. At the same time, the surface presses the window against the gasket.

Abstract: A battery cell characterized by a plurality of cell plates housed in a container that includes a window adjacent to the edges of several plates. A triangular member of resilient material is attached at its base to the edge of at least one of the plates. The sides of the member contain two lands and the tip of the member contacts the window. The interface between the tip and the window is visible through the window as a single line. As the plate increases in size, the edges of the lands contact the window producing additional lines; the number of lines representing the gradual diminution in the cell life.

Abstract: A pair of breaker contacts are opened and closed by the pivotal movement of a breaker lever carrying one of the breaker contacts for engagement with the other breaker contact which is stationary. The breaker lever is pivotally supported on an upright pivot post which is formed integrally with a cupshaped container constructed from an inexpensive plastic material, and the end of the pivot post is received in a reinforced opening of a cover member secured to the cup-shaped container so as to prevent the pivot post from being undesirably deflected during the pivotal movement of the breaker lever.
