Filed: 1978-09-13
Granted: 1981-02-17
Abstract: A B S T R A C T A subterranean formation containing, for example, oil shale is prepared for in situ retorting by initially excavating a pair of spaced apart voids, leaving an intervening zone of unfragmented formation between the voids.  The inter-vening zone has substantially parallel free faces adjoining the void.  A plurality of elongate blasting holes are formed in the intervening zone of unfragmented formation, the longitudinal axis of each blasting hole being substant-ially perpendicular to the parallel free faces of the intervening zone.  At least two deck loads of explosives are placed in each. blasting hole with each load longit-udinally spaced apart from each adjacent charge by stemming. The loads of explosive are then detonated in a single round of explosions with a time delay between adjacent loads for expanding formation in the intervening zone toward both voids.  The fragmented mass of formation particles is then retorted to recover, for example, shale oil from the oil shale.

Abstract: THRUST REVERSER FOR AN ASYMMETRIC      AIRCRAFT EXHAUST NOZZLE                                   Abstract A thrust reverser is provided for use with an asymmetric aircraft gas turbine engine exhaust nozzle. The thrust reverser includes a movable aerodynamic flap downstream of the asymmetric nozzle casing which is rotatable about one pivot in order to effect in-flight thrust vectoring through deflection of the exhaust stream, and which is also independently rotatable about another pivot to effect thrust reversing. In the reverse thrust mode, the leading edge of the flap is immersed into the exhaust stream, thereby splitting the stream into two portions, one of which is deflected upward and forward by a turning vane incorporated into the leading edge of the flap, and the other portion of which is deflected downward and forward by a hinged lip connected to the flap trailing edge. The thrust reverser thus permits the exhaust stream to be ejected in the vertical plane to produce reverse thrust without an accompanying pitch moment even though the exhaust nozzle is not symmetrical in the vertical plane.

Title: Method and apparatus for fuel ignition system including complete cycling of flame relay prior to trial for ignition
Inventor: MATTHEWS RUSSELL B

Granted: 1982-10-19
Abstract: METHOD AND APPARATUS FOR FUEL IGNITION SYSTEM INCLUDING COMPLETE CYCLING OF FLAME RELAY PRIOR TO TRIAL FOR IGNITION        Abstract of the Disclosure When a call for heat is established, a flame relay is actuated for a predetermined time by means of a cycling timer.  Upon this initial actuation, the flame relay inhibits a checking relay and initializes a trial-for-ignition (or simply "ignition") timer.  After the cycling timer times out the flame relay has been completely cycled, which establishes operativeness of the flame relay and flame sensing circuitry, the checking relay is enabled and actuated for the ignition period. The checking relay then actuates the pilot valve and a spark generator to start a pilot flame.  If a flame is sensed, before the ignition timer times out, the flame relay actuates the main valve and establishes a holding current for the ignition timer so that the checking relay continues to be energized.  If a flame is not sensed during the trial period, the ignition timer disables the checking relay, thereby de-energizing the pilot valve before the main valve is opened.  If there is a fault in the flame relay or flame sensing circuitry, the checking relay is inhibited from operating.  Both timers are preferably electronic timing circuits using capacitors in such a manner that circuit faults do not cause system malfunction. In an alternative embodiment, separate flame sensing circuits control the operation of the flame relay and the ignition timer.

Abstract: LIQUID COOLING SYSTEM FOR HERMETICALLY SEALED               ELECTRIC MOTOR            Abstract:           A cooling system having an electric drive motor utilizes a portion of the sub-cooled liquid which would otherwise be passed from the condenser through an expansion device to the evaporator to cool the motor.  The rotor cooling passage (35) which extends longitudinally through the outer portion of the rotor has its outer-most surface (42) (that is, the surface farthest removed from the center of the motor) shaped in an arc having the same center as as the center of the rotor.  This ensures even distribution of the cooling liquid under the high centrifugal forces developed during motor operation.  The stator has a passage from its outside surface inwardly to the longitudinal cooling portion of the stator.  The inwardly extending passage (36) includes an orifice (51,55), sufficiently large to prevent contamination problems but of an  appropriate size to ensure good throttling and thus provide good heat transfer.  The cross-sectional areas of the cooling passages are sized to minimize the velocity of the generated vapor.

Abstract: -11-                 RCA 72,814 Abstract of the Disclosure A record is removably subject to occupancy of a protective caddy comprising a jacket and a record retaining spine.  The record is enclosed in the caddy such that a first side of the record is associated with a given side of the spine.  To load a record into a player, such as a video disc player, an occupied caddy is inserted into an input slot provided in the player.  A record extracting mechanism mounted in the player removes the retaining spine and the associated record from the jacket during jacket withdrawal subsequent to the occupied cover arrival at a fully inserted position in the player, whereby the record and the spine are retained within the player. A sensing member mounted in the player in the vicinity of the input slot is deflected in a first direction in response to engagement with an occupied cover during insertion thereof into the player with the given side of the spine facing upward, and is deflected in a second direction, opposite to the first direction, in response to an occupied cover insertion with the given side of the spine facing downward.  An indicator responsive to the location of the sensing member and mounted on the front instrument panel of the player provides an indication of the record side subject to playback.  An actuating member, subject to engagement with the spine upon occupied cover arrival at the fully inserted position in the player locks the sensing member in the position to which it was deflected during the occupied cover insertion, throughout the period of retention of the spine in the player.
