Abstract: MICROWAVE OVEN HAVING L-SHAPED ANTENNA          Abstract of the Disclosure A microwave oven has a rotary antenna of sub-stantially L-shaped configuration from which microwaves are radiated into a heating cavity.  This antenna is constituted by a first antenna portion which extends perpendicularly from a wall of the heating cavity and has a length sub-stantially equal to a quarter of the wavelength, and a second antenna portion which extends parallel to the wall and has a length substantially equal to half the wavelength.  The arrangement improves over prior microwave ovens by radiating microwaves in two perpendicular directions and, as a result, distributing the microwaves more evenly inside the heating cavity.  Excessive heating of the shelf supporting the food is avoided, the full power of the energy being applied to the food.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is an apparatus for separating from ruminant animal feces the undigested fibrous material that is preponderantly short pieces which consist of bundles of capillary tubes.  The apparatus includes a supply tank to receive a slurry that contains ruminant animal feces and added liquids including urine with means in the supply tank for agitating the slurry to make it substantially homogeneous.  A first stage separator separates the slurry into a filtrate consisting preponderantly of liquid and fine solids, and a filter mass consisting preponderantly of the short pieces of fibrous material.  The first stage separator includes a first stage hopper, a foraminous separator drum which is rotatable on a horizontal axis at the bottom of the hopper, a squeeze roller surmounting the separator drum slightly downstream of the vertical diameter of the drum, and means urging the squeeze roller against the separator drum with heavy pressure to compress the capillary tubes and express the majority of the liquid therefrom.  A filtrate discharge is provided for the separator drum with the filtrate discharge including a conduit for conducting the filtrate to a storage means for use as liquid fertilizer.  Diverter means are provided for varying the flow to the conduit of the filtrate discharge between substantially zero and substantially 100% with the balance of the filtrate returning to the supply tank.  A filter mass scraper blade bears on the separator drum downstream from the squeeze roller.  Means are provided for pumping the slurry from the tank into the hopper and means rotate the separator drum to force the filter mass forwardly beneath the roller and onto the scraper.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to the field of closed loop film or tape information, storage and retrieval systems and in particular to a film transport system for transporting a closed loop of film about a defined pathway.  A relatively large number of turns or strata of film strip layers typically overlie one another in a sub-pathway along the film pathway.  The individual film layers in the sub-pathway are continu-ously being translated, and the translation rate of each film layer is slightly different from that of adjacent such film layers.  There is a definite tendency for adjacent film layers to seize and bind against one another resulting in an equipment operational failure.  Previous efforts to alleviate this problem have involved hand manipulation of film layers to keep same in a "free" condition which is considered an undesirable solution because of safety considerations and because of the need to minimize continuous operator attention during machine operation.  The present invention provides a transport system including means for automatically and continu-ously oscillating the film strip segments in a convo-lutely would sub-pathway used for storing multiple film strip segments of the film's closed loop so as to prevent film seizing from occurring during transport system operation even when very large film lengths are employed relative to the size of the sub-pathway.

Abstract: ABSTRACT      An in situ oil shale retort having a top boundary of unfragmented formation and containing a fragmented permeable mass has a pocket at the top, that is, an open space between a portion of the top of the fragmented mass and the top boundary of unfragmented formation.  To establish a combustion zone across the fragmented mass, a combustion zone is established in a portion of the fragmented mass which is proximate to the top boundary. A retort inlet mixture comprising oxygen is introduced to the fragmented mass to progagate the combustion  zone across an upper portion of the fragmented mass. Simult-aneously, cool fluid is introduced to the pocket to prevent overheating and thermal sloughing of formation from the top boundary into the pocket.

Abstract: HIGH-GAIN PROJECTION SCREEN     Abstract of the Disclosure Lenticular protection screens of improved optical accuracy and uniformity are produced by deriving the specular surfaces of all lenticules within at least a major screen area from a common unitary optical surface, typically using replication by electroforming.  The initial master surface is typically formed by conventional machin-ing and polishing of a body having axial symmetry in the general shape of an ogive.  The unitary convex surface of revolution of the ogive is repeatedly replicated, and like sections of each replica are isolated and assembled on a transparent reference surface.  The assembled sections are adhered to a stiff back, and the optical assembly face is replicated.  Multiple replicas of the initial assembly are typically again assembled and replicated, leading ultimately to unitary panel units which form the projection screen.      For drive-in theaters or the like, each lenticule is pref-erably made non-uniform in vertical curvature in a manner which increases the image brightness for a large majority of the viewers.  Various shapes of the viewing area can be fitted by suitably formed lenticules.  Certain non-symmet-rical viewing areas are closely fitted by tilting symmet-rical lenticules about the optical axis of the projector.          Reflected light from spurious sources is further reduced by baffles which project toward the audience from bound-aries between concave lenticules.

Further apparatus measures engine speed and induction passage pressure and compares the induction passage pressure with a control reference number derived from the induction passage pressure reference number corresponding to the measured engine speed.  When the throttle is in the idle position and the induction passage pressure signal exceeds the reference, a throttle stop control loop is closed on engine speed to maintain a predeter-mined engine idle speed.  However, when the throttle is in the idle position and the induction passage pressure signal does not exceed the reference, the throttle stop control loop is closed on induction passage pressure to maintain substantially the reference pressure, whereby throttle position during vehicle coastdown is controlled according to a predetermined stored schedule.  The control reference number may be shifted between the induction passage pressure number and a higher number as the control is shifted between idle speed and induction passage pressure control to provide hysteresis.

Upon the continued subjection of a segment of the metallic sheath to concentrated heat; e.g., a localized fire, at least a portion of the acids and gases resulting from insulation decomposition is absorbed from the filler material positioned within the heated segment and, in combination, the volume of such filler material within the heated segment, expands to provide substantially complete cross-sectional occupation of any hollow spaces within the heated segment, resulting in a structural blockage to the longitudinal flow of acids and gases from within the heated segment into adjacent segments of the electrical cable.
