Abstract: ELECTRICAL SWITCH FOR                  IGNITION IN GAS APPLIANCES            Abstract of the Disclosure Disclosed is a switch structure for use in a gas-fired appliance.  The switch is simultaneously operated by rotation of a gas valve on an appliance such as a cooking stove.  The switch has a semi-circular cam body disposed within a housing.  The cam body is secured to the stem of the gas valve for rotation therewith.  An arcuately extending cam guide is located on the periphery of the body and extends transversely of the axis of rotation.  A cam lobe is also provided on the cam body immediately adjacent the cam guide and only at one side thereof.  A flexible wire contact element is engagable with the cam guide and is actuated by the cam lobe to make electrical contact with a stationary contact element when the cam body is rotated in one direction.  The flexible wire contact is engagable with the cam guide and directed away from the cam lobe to avoid electrical connec tion when the cam body is rotated in the opposite direction, during, for example, turning off and/or adjusting the level of; the flame of the gas burner.

Abstract: Abstract of the Disclosure A closed self-contained system (method and apparatus) for efficiently extracting oil and other hydrocarbons from oil-bearing shale rock in which shale, which may be preheated to remove water and hydrocarbons which vaporize below about 600°F., is advanced in the form of discrete individual pieces along a pathway in a substantially evacuated zone (e.g., less than 50 torr) while in the presence of heat energy sufficient to raise the temperature of the shale (e.g., to 600° to no more than 900°F.) to cause the oil and other hydrocarbons to be liberated as a vapor in the evacuated zone.  The shale advances in proximity with at least one condenser surface so that oil and other hydrocarbons are condensed and recovered from the liberated vapor.  The system operates at temperatures which are at all times below 990°F., and generally below 700°F., to extract the oil from the oil-bearing shale in a relatively short period of time (e.g., 30 to 360 minutes).          Through use of multiple condensers cooled to differing condenser temperatures (e.g., from 300°F. to -200°F.), fractional condensing and selective recovery of hydrocarbons is obtained.          The system employs a simplified apparatus including a housing, means to evacuate the housing, a pathway for advancing the shale through the housing, means to supply energy to the pieces of shale advancing within the housing, at least one condenser in proximity with the pathway, means to supply cooling medium to the condenser surface, means to remove oil condensing on the condenser surface, and means to introduce and remove shale material from the housing while maintaining the desired low pressure and temperature conditions.            The system is characterized by its operation to extract oil from shale without release of environmental con-taminants to the atmosphere, or return of contaminants to the soil.                     -1a-

Abstract: ABSTRACT OF THE DISCLOSURE       A drive shield is formed with a series of drive of cutter members of elongate shape supported in side-by-side relationship around a tunnel wall by a frame and fluid rams are interposed between the frame and the members for effectively relative displacement.  To preclude relative movement between the drive members when the frame is shifted by operating all the rams in unison a plurality of locking mechanisms with levers spring-biased into catch plates and effective between neighbouring pairs of members ensures all the members lock together when they have all been shifted up by the rams.  The levers are released by plates on the frame however when the frame becomes fully drawn up to permit the members to be displaced individually again.  Alternatively an analogous hydraulic control system feeds identical flow rates of fluid to the rams when the frame is shifted independent of the prevailing forces or pressure to inhibit relative movement between the drive members.

Abstract: ABSTRACT OF THE DISCLOSURE    A flow-reversing, regenerative, desiccant air dryer system absorbs moisture, oil droplets, and carbon particles from the incoming air during compression in a compressed air system.          Once sufficient air pressure has been attained in an air pressure reservoir, control valves direct the flow of atmospheric-pressure air, heated by passing through the warm compressor cylinder, in a reverse direction through the air dryer.  The reverse flow of heated, atmos-pheric pressure air both purges the trapped oil, carbon particles, and condensed liquid water and removes the moisture from the desiccant.

Abstract: ABSTRACT OF THE DISCLOSURE     A plural switch matrix is connected as a direct ac-to-ac converter between an induction generator and an a-c load. The generator provides three-phase output energy which is switched and controlled by the converter, to supply a controlled three-phase quasi-square wave (QSW) voltage to a load. The converter switching provides periodic shorts across the generator terminals, translating some of the mechanical input energy into electrical energy to sustain the generator field. The converter is regulated by gating signals from a combinational logic circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to furniture assembled from individual components.  Many such furniture-assembly programmes are known, including one which makes use of hollow cubic or rectangular elements which can be built up to form a variety of pieces of furniture utilizing moulded-on connecting elements, However, these hollow structural elements are costly to produce and, when shipped, take up almost the same space as the assembled furniture.  The present invention proposes to design furniture assembled from individual components in such a manner as to retain the simple and compact components while, at the same time, simplifying the assembly such that the same can be carried out rapidly and without any tools by any layman.  Accordingly, the furniture is assembled from individual components compris-ing vertical lateral walls, partitions, or the like, formed from individual lateral parts.  The individual lateral parts each consist of a lateral panel with U-shaped frame elements on their vertical edges.  One horizontal edge of the lateral panel projects beyond the frame elements and an opposite hori-zontal edge is correspondingly recessed in relation to the frame elements.  Faces of the frame elements facing the lateral panel and located at right angles thereto are provided with suitably-spaced blind holes for dowels.  Bottoms, tops, compart-ment bottoms or the like are in the form of rectangular bottom panels, under-surfaces of narrow sides of which are provided with transverse grooves by means of which the panels are sup-ported on dowels fitted to the lateral parts.

Abstract: VARIABLE COMPRESSION RATIO PISTON                  Abstract of the Disclosure A two part variable compression ratio (VCR) piston assembly having an outer member movable relative to an inner member to vary the compression ratio of an internal combustion engine and a hydraulic system utilizing oil from the lubrica-tion system of the engine for automatically controlling the relative movement of the members to maintain a predetermined maximum combustion chamber pressure.  A hydraulic circuit includes an upper and a lower chamber which expands and contracts conversely upon relative movement of the piston members, and a system for supplying oil to the upper chamber and to the lower chamber via the upper chamber, for discharging the oil from the upper chamber in a manner which gradually changes the compression ratio of the cylinder until a pre-determined maximum combustion chamber pressure has been achieved, and which tends to maintain the maximum combustion chamber pressure after it has been achieved.  The lower chamber is disposed adjacent the piston ring area and a sealing ring is utilized as a valve for regulating oil flow from the upper chamber to the lower chamber.
