Abstract: An apparatus for making fiber reinforced plastic members. The apparatus employs a rotatable mandrel (18) and a winding head (16) with a unique arrangement by which to effect relative longitudinal movement between the winding head (16) and the mandrel (18). Either the winding head (16) or the mandrel (18) may be longitudinally fixed. The other of those members is mounted on a trolley (30) that can be reciprocated parallel to the longitudinal axis (42) of the mandrel (18). This reciprocation is effected by having a dog means (51) mounted on the trolley (30) that is movable between a first and second position. In the first position the dog means (51) engages a lug (50) on a drive means to move the trolley (30) in one direction, and in the second position the dog means (51) engages the lug (50) to move the trolley (30) in the opposite direction.

Abstract: A device for holding a cup (C) and maintaining liquid in the cup (C) while travelling in a vehicle includes a device (10, 100) for carrying the cup (C). The cup holding device (10, 100) is carried by a support member (20, 110) in such a manner so as to permit rotation of the cup holding device (10, 100) on a first axis. A stand (30, 40, 50, 120, 130, 140) carries the support member (20, 110) in such a manner so as to permit rotation thereof on a second axis generally 90.degree. of the first axis. The stand (30, 40, 50, 120, 130, 140) is adapted for mounting at a desired location in the vehicle. The cup (C) is thus free to act under its own inertia to maintain the liquid therein.

Abstract: A thermistor temperature sensor having non-linear electrical response characteristics with temperature, a material constant, beta, that varies with temperature, and providing an output signal indicative of the temperature desired to be measured is utilized herein. A time dependent signal having a configuration that offsets the non-linear temperature dependence of the sensor output signal is generated and compared to the sensor output signal. Whenever the sensor output at least equals that of the offsetting signal, a comparator generates an output signal that, after appropriate delay, is indicative of the actual temperature. The material "constant" of the sensor is maintained substantially constant over at least a substantial range of temperatures. Additionally or alternatively, the sensor is energized in such manner as to substantially eliminate self-heating induced variations in the sensor output signal.

Abstract: A circuit and method for the display of a high frequency periodic signal on a display (21) having a maximum response frequency less than the periodic signal frequency includes a signal period counter (12) for counting the number of periods in the high frequency periodic signal, a sampling control counter (16) for counting at a frequency substantially greater than the frequency of the high frequency periodic signal, and a comparator (17) for comparing the counts in the signal period counter (12) and the sampling control counter (16) and indicating a match thereof. When a match count is indicated, some electrical parameter of the high frequency periodic signal is sampled and held by a sample and hold circuit (20) until the next match count is indicated, thereby accurately reproducing the high frequency periodic signal at another frequency in a range of frequencies from zero up to and including the maximum response frequencies of the display.

Abstract: A mobile apparatus for cleaning sewers, catch basins and the like includes a debris collection chamber mounted on the rear of a vehicular chassis. A vacuum conduit communicates with the chamber and is adapted to be lowered into the sewer. A vacuum fan also communicates with the chamber and draws air through the conduit and chamber thereby picking up debris from the sewer. As the debris enters the chamber, the configuration thereof creates a rapid decrease in the air flow velocity and otherwise interrupts the flow so that material entrained in the air is deposited in the chamber. The configuration of the chamber also permits facile discharge of the debris out of the bottom of the chamber in that one end wall of the chamber is swingable to open the bottom thereof. This same end wall also carries a hose reel for use in flushing the sewer. Because the debris which is picked up may well include water, means are provided to drain the water from the chamber.

Abstract: A free-standing, prefabricated, knock down, readily assembled and disassembled, relocatable vertical wall or space divider. Such wall dividers are useful for partitioning buildings and/or office complexes. The wall is made up of a plurality of individualized and decorative flush panel units which are interchangeable and which are adapted to be readily inserted within quadrilateral openings delineated by a novel wall frame and locked into place by hidden spline members that are mounted in the wall frame for translatory movement. The wall frame is fabricated in a novel assemblage of unique components which can present either a metallic or wooden exterior finish surface. The configuration of the wall frame components provides for lateral walls to extend outwardly not only at modular locations but also from any other desired location by use of novel adapters. The panels may be removed, redecorated and replaced as needed. Shelving or other appurtenances are attachable to the hidden spline members.
