Abstract: MISCIBLE FLOODING OF PREVIOUSLY     WATER FLOODED RESERVOIRS     (D#77,400-TCRL-010) ABSTRACT     The invention is a tertiary hydrocarbon recovery method to be used with reservoirs which communicate with an aquifer and that have been previously waterflooded.  The method is performed by injecting a miscible solvent into the reservoir to form an oil bank from the hydrocarbons therein.  The oil bank, followed by the miscible solvent, is driven through the waterflooded region of the reservoir.  The oil bank drives out a significant portion of the water in the waterflooded region and resaturates the waterflooded region with oil.  The following miscible solvent bank sweeps the oil from the region newly resaturated with oil.          Complete production of the oil is delayed until after the leading edge of the oil bank has passed through the previously waterflooded regions of the reservoir.

Abstract: ABSTRACT         The invention provides a digital switching network for switching through subrate channels.  The multiplexed sub-scriber's channels contain eight-bit words, each bit of which can form part of another signal.  The number of bits in each word for a single signal is determined by the original rate of the signal.  Each of the signals must have the possibility of being switched through to another destination.  For that pur-pose it may be necessary to change the position of bits within a frame.  Hence a separate time and space stage has been arranged between the input time stage and the switching matrix.  After that the switching matrix switches through eight-bit words.          The positions of bits within a word can be exchanged in an additional space stage between the switching matrix and the output time stage in order to make it possible to fill the out-going frames as completely as possible.

Abstract: ABSTRACT A clip-on fixture system for holding the socket baby of an incandescent lamp to a panel. The system includes a self-biased clip member connected to the bottom wall of the socket body that radially extends from the body into a locking relationship with a hold-down member connected to the panel. The clip member forms a holding recess that receives a radially transverse bar of the hold down member after biased insertion through a passageway under the bar. The clip member is released from the biased mode to the unbiased mode thus locking the clip member under the bar and holding the socket body to the panel. The clip member can be removed from the hold-down member by reversing the mounting process.

Abstract: ABSTRACT OF THE DISCLOSURE          A geometric processing system comprising a data converter means which divides a plane forming a graphic model into one or a plurality of triangles by diagonal lines drawn from a vertex thereof, and which produces vertex coordinates of triangles.  Relying upon the data from the data converter means, a normal vector operation means finds normal vectors pointing outwardly of the triangles and point at infinity coordinates thereof.  An interference test operation means calculates values of 4 x 4 determinants as well as logic values of the determinants; and interference point coordinate calculation means operates in reliance upon the operated result of the interference test operation means.  The vertex coordinates of two triangles extracted from a figure for determining the interference and point at infinity coordinates thereof, are suitably selected to imagine a triangle.  A 4 x 4 determinant is constituted by a vertex coordinate of the triangle and by a coordinate of another given point, and the 4 x 4 determinant is operated by the operation means, and the interference point coordinate calculation means is operated based upon the operated result.

Abstract: AN ADAPTIVE ANTENNA FOR REDUCING MULTIPATH FADES            Abstract The present invention relates to an antenna arrangement for reducing multipath fades.  The antenna arrangement comprises a curved main reflector disposed confocally with one focal point of a subreflector, and a feed arrangement.  The feed arrangement comprises at least a pair of feed horns and a selectively movable plate reflector disposed between the feed horns and the subreflector along a feed axis of the antenna arrangement. The feed horns are disposed adjacent each other with the aperture of each of two feed horns covering one-half of the image of the main reflector.  By selectively orienting the plate reflector so that one of the two multipath beams arrives with its central ray disposed orthogonal to the aperture of the feed horns, the contribution from each half of this beam received at each feed horn, for a particular frequency band, is equal and can be subtracted from the other half beam  signal to cancel its effect without the need for an equalizer.

Abstract: AIRCRAFT TERRAIN CLOSURE WARNING SYSTEM    WITH DESCENT RATE BASED ENVELOPE MODIFICATION             Abstract of the Disclosure Aircraft ground proximity warning systems that provide the pilot with a warning in the event that the closure rate with terrain is too high have the problem that when such systems are used in air-craft that are intentionally flown at high descent rates, such as occur in dives, nuisance warnings can occur.  In order to minimize the problem, the criteria necessary to generate a terrain closure warning are modified as a function of the descent rate of the aircraft (12, 14, 30, 40, 42, 44) to prevent the closure rates encountered as a result of high descent rates from generating nuisance warnings.

Abstract: SECTOR IDENTIFICATION METHOD FOR HARD SECTORED HARD FILES                             ABSTRACT          A disk file control provides for tracks having defective sectors by forming sectors as a single, uninterrupted stream of serial data containing both identifier (ID) and data portions.   Reading a single ID portion characterizes the entire track to permit writing data without a separate revolution to read the ID field.  The ID information includes the offset of the first logical sector on the track and the locations of defective sectors that must be skipped.  As soon as one ID is read, the location of the addressed sector is ascertained and the ID data for the sector to be written is formulated so that the entire sector including both ID and data can be written when the sector first approaches the transducer.  If alternate sectors are permitted on a subsequent track under the strategy being used, a single ID on the track will define where the logical sectors making up that track will appear (either the physical sector location on the track or at an alternate location on the next track).

Abstract: ABSTRACT OF THE DISCLOSURE      The invention contemplates hydraulic-lift mechanism which employs a power integrator in the connection between a charged hydraulic accumulator and the actuator for a vertically position-able load; the power integrator, additionally, has a prime-mover connection, and the pressurized charge of the accumulator is advisedly set to fully accommodate a preselected level of average load upon the actuator.  The hydraulic circuit importantly includes check valves, with a pilot-operated check valve inter-posed between the power integrator and the accumulator and another pilot-operated check valve interposed between the power integrator and the load actuator.  The pilot-operated check valves cooperate with other check valves to assure automatic transfer of hydraulic fluid under pressure from the accumulator to the load actuator, and vice versa, as may be determined by selected control of or via the power integrator.  The system of check valves also cooperates with pump action to assure that adequate fluid is drawn from a sump and is deliverable for pilot-operated functions; stated in other words, with minimum reliance upon the sump, the system provides maximum conservation of energy in effecting such transfer of pressurized fluid, from and to the accumulator, as may be involved in any controlled lift or descent of any load, within the capacity of the system.
