Abstract: Apparatus for producing a chlorine gas or a hypochlorite compound comprising a housing, a plurality of carbon electrodes arranged in series, with electrodes being spaced to form chambers between adjacent electrodes and one or more hollow tubes extending through the electrodes for delivering a chloride salt brine solution to the chambers. Each chamber is divided into an anode compartment and a cathode compartment by a chloride ion permeable membrane. A fluid sealing ring or rings around the outside perimeter of each electrode and around each hollow tube separates the permeable membrane from each electrode thereby dividing each chamber into an anode compartment and a cathode compartment divided by the membrane. The salt solution is applied to a hollow tube and flows through apertures therein into each anode compartment. A negative D.C. current is supplied to the electrode on one end of the series of electrodes and a positive D.C.

Abstract: A meat flavored vegetable protein product comprising a textured deflavored vegetable protein having absorbed thereon a rendered animal fat, said protein optionally being admixed with a seasoned sauce.

Abstract: Non-ferrous metals are recovered from metal bearing ores or other metal sources in substantially quantitative yields by treating a finely divided metal bearing material with an aqueous inorganic acid to form a slurry and baking the slurry at atmospheric pressure and at a temperature of about 350.degree. to 800.degree.C. or higher under quiescent conditions for a period of time sufficient to convert the non-ferrous metals into soluble salts. The fumes from the baking process are scrubbed with a dilute acid solution to extract volatile metal salts. The residue is leached with an appropriate solution or solutions to recover the soluble metal salts which are then recovered from the solution by conventional techniques.

Abstract: An ignition control system for use in internal combustion engines includes apparatus for sensing maximum pressure due to combustion in an engine combustion chamber during one cycle of operation, for determining when a rotatable member of the engine rotates through a certain predetermined angular position, and for adjusting the ignition timing on a subsequent cycle so that the occurrence of maximum pressure in the chamber coincides with rotation of the rotating member through the predetermined angular position.

Abstract: Apparatus for the removal of noxious material from a contaminated gas stream comprising (1) a lower portion having a liquid reservoir with means for receiving a contaminated gas above the level of said liquid and a substantially vertical elongated duct positioned centrally above said liquid level, (2) a central portion containing fan means positioned in axial alignment above said duct, the operation of said fan means causing an upwardly spiraling vortex of contaminated gases and atomized liquid from the liquid reservoir through said duct and fan means thereby intimately admixing the contaminated gas and atomized liquid and (3) an upper portion through which purified gases exit and wherein the atomized liquid containing said contaminants is coalesced and flows downwardly by gravity to said liquid reservoir.

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.

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.

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.

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.

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.

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.
