Abstract: A control circuit for a windshield wiper motor which utilizes a plurality of infrared emitters that emit a chain of infrared pulses towards a plurality of infrared sensors. When rain passes between the infrared emitters and the infrared sensors, it will interrupt the flow of pulses therebetween. A control circuit senses the missed pulses and selectively energizes a low-speed, mid-speed and high-speed winding associated with the wiper motor for varying the speed of the windshield wipers. The device automatically controls the operation of the windshield wipers of a vehicle.
Abstract: A woven electrical transmission cable A is illustrated which includes a plurality of warp elements (12, 12, 14) interwoven with a weft element (16). A number of the warp elements are ground conductors (10) and a number are signal conductors (12). The ground and signal conductors are arranged in clusters (D, E) which include signal conductor pairs (12a, 12b and 12c, 12d) isolated by ground conductors (10a-10c and 10d-10f), respectively. An input signal is split at the input (20, 24) of the cluster between the signal conductor pair which is then combined at the output to provide a single output signal (28, 30). The location of the ground conductors relative to the signal conductors is fixed in the cable by interweaving of the weft (16) and warp binder yarns (14) together with the warp conductors (10, 12) whereby the characteristic impedance is controlled.
Abstract: A portable multi-directional hand truck A is illustrated including a frame 10 having a toe plate 14 and a pair of rear indexing wheel assemblies B. Indexing mechanism D is connected between the frame 10 and a contoured wheel C in each wheel assembly having a first position in which wheels C are aligned for forward movement and a second position for movement transverse to the forward movement. Wheels C include a contoured surface 54 for forward movement and a rounded contoured surface 56 for transverse movement. Surface 56 provides a rounded support surface over which the load may be broken and transported in which configuration the load is supported in a raised position for transporting long loads transversely down narrow passageways without dragging and sagging ends of a long load.
Abstract: A woven jacket (A) and woven transmission cable (B) are woven together as one-piece. A common weft element (18) is interwoven between the cover (A) and cable (B) which are woven simultaneously on a loom. Weft pick (18a) is woven in the cover exclusive of the cable while weft pick (18b) is broken out of the cover and woven in the cable to physically attach these together.
Abstract: A method and apparatus for opening and mixing the fibers from a plurality of bales according to a predetermined mixture. The device includes tongs-like gripper means which press into the fiber bales for removing fibers therefrom. A measuring means and a control means determine the width of opening of the gripper means. A control circuit is provided for receiving a signal representing the weight of the first pick-up from a particular bale and the weight of the fibers deposited in a receiver container. When the sum of these signals is equal to the preset desired weight of the fibers that are to be deposited in the receiver container, a compared signal is produced causing the tongs on successive pick-ups to be opened to a lesser degree. As a result, a high degree of accuracy is obtained when mixing to a predetermined ratio while maintaining a high production output.

Abstract: A socket wrench device is provided as including a wrench handle having a drive head which circumferentially engages a socket having a plurality of circumferentially spaced side openings facilitating use in a minimum amount of vertical space. In an advantageous form of the invention, the drive head of the wrench handle includes a ratchet drive mechanism having a plurality of pawl fingers which engage corresponding side openings in the socket.
Abstract: A manipulatable game which includes a spherical support member which has a plurality of circular tracks extending about the surface thereof which intersect each other at right angles. Movable members are carried on the tracks for being rotated about the spherical support member and shifted from one track to another at a junction of two of the tracks so that the movable members can be arranged according to predetermined patterns. The movable members are of different colors and have characters of the alphabet printed thereon.

Compressible protrusions (58) carried on molded side wall ribs (54, 56) are compressed in lateral side cut grooves (66, 68) to resist rotation of gripping jaws (14, 16) about the axis of attachment bolt 38 during weaving and bobbin transfer along with other molded structural features of the molded housing 28.
Abstract: Heater apparatus is disclosed having a metal firebox in which fuel is burned and an outer ceramic enclosure having ceramic mass walls which absorb excess heat when the heater produces more heat than is required and distributes the heat gradually by radiation after the heater output becomes less than the heat stored in the ceramic mass. The ceramic mass walls are spaced from the metal firebox walls to provide air passages through which air may be circulated by means of a blower so that rapid heating may be had of the interior space when the firebox is initially fired by transferring the heat radiated from the metal walls directly into the room by forced convection. After the interior space is heated to a desired temperature, the blower may be cut off and the room may be heated more slowly at a more even temperature by radiation from the ceramic mass.
