  • Patent number: 3944020
    Abstract: A stereophonic speaker headrest for motor vehicles includes a rigid interior shell and a padded cover. The rigid interior shell is generally hollow with a pair of opposed side wing members having speaker attachment structure therein for holding a speaker in each wing. The hollow portion of the rigid interior shell adjacent the speaker attachment structure forms an acoustic chamber. The padded cover provides substantial padding over the front and rear surfaces of the rigid interior shell, including the area in front of the speakers.

  • Patent number: 3943641
    Abstract: An audience response system includes a console having a plurality of pairs of lamps in which one lamp of each pair is grouped with corresponding ones of the lamps of the other pairs. The system also includes a plurality of switches, each for controlling the lighting of a different pair of lamps, and a plurality of timers, each of which is activated by a different one of the switches. When a particular one of the lamps of a pair is lighted by the associated switch, then the corresponding timer is also activated, and when the other lamp of the pair is lighted, the corresponding timer is deactivated. An additional switch is provided to activate an additional timer and deactivate the plurality of timers.

  • Patent number: 3940609
    Abstract: Angular position measuring apparatus includes a prism mounted on a shaft whose angular position is to be determined, and a light source for directing a beam of light onto the prism. The prism is formed so that the light beam enters one surface of the prism and is refracted by another surface and caused to be directed in different directions as the prism, and thus the shaft, is rotated. Also included is an array of photo detectors positioned so that the refracted light impinges on various ones of the photo detectors depending upon the angular position of the shaft. The photo detector on which the light impinges is thereby caused to generate an electrical signal which is applied to utilization apparatus.

  • Patent number: 3936039
    Abstract: A load-levelling shock absorber unit including a guide piston and piston rod and a first surrounding ride control cylinder, one of which is adapted to be connected to a first sprung mass and the other of which is adapted to be connected to an unsprung mass; an oil reservoir cylinder surrounding the ride control cylinder; and an expansible lift cylinder. The ride control, oil reservoir and lift cylinders are all preferably concentrically arranged and are of the hydraulic type. The piston rod reciprocates within the ride control cylinder and, so long as the piston is centrally positioned within the first cylinder, a lagged control valve does not displace sufficiently to allow repositioning of the outer wall of the lift cylinder.

  • Patent number: 3936076
    Abstract: A shock absorber for use in combination with either or both a seat post and front wheel fork of bicycles and the like. The shock absorber includes a pair of elongated tubes adapted to fit together in a telescopic fashion. The wall of each tube has a pair of slots on opposite sides of the tube so that when the tubes are fitted together, the slots are in general alignment. Plugs are fitted in each tube to compress therebetween a resilient wire mesh pad. A tab is fitted in the slots to keep the tubes together and to enable the tab to slide in the slots of the interior tube as the tubes slide relative to each other. The wire mesh pad serves to absorb vibrations and shocks applied to either tube.

  • Patent number: 3932277
    Abstract: Method and apparatus for filtering and permanently separating the serum fraction from the cell fraction of centrifuged blood and the like. A separator head is passed through the serum and is positioned at the interface of the serum and the heavier red cells. As the separator head is positioned serum passes through a self-sealing passage in the separator head and into a collection tube that positions the separator head. Upon withdrawal of the collection tube the passage in the separator head closes sufficiently to effectively block the passage and the serum can be poured from the collection tube. The collection tube can be reinserted to pour off measured volumes of the serum.
