Patent GB-2044567-A (GB)
Title: Aerial direction selectors
IPC: H01Q3/00
Filed: 1979-03-02
Abstract: An aerial direction selector for use with a radio receiver in which a tuner generates a voltage at terminal 11 varying in response to the frequency to which it is tuned, comprises means for connection to an aerial system and means (13 to 16) responsive to the voltage to cause the aerial system to receive selectively in a desired direction. Appropriate fixed aerials can be connected to an output in response to the voltage. Or a rotatable aerial can be rotated in response to the voltage. Level detectors 13 and 14 switch aerials B and A via P1N diodes to output 28 according to tuning voltages in channel, B or A groups and the aerial in use is indicated by LED's 25. If the received signal corresponds to a third group of channels neither detectors 13 or 14 responds and a bistable 32 switches aerial 35 via P1N diodes to the output 28. <IMAGE>

Patent GB-2061649-A (GB)
Title: A circuit arrangement for converting the frequency of an alternating voltage into a digital value
IPC: H03M1/00
Filed: 1980-07-21
Abstract: The frequency of an alternating voltage is measured by producing trigger pulses for each cycle or part cycle of the voltage and applying to a computer which performs a program to produce a digital value representing the frequency of the trigger pulses and therefore an indication of the frequency of the alternating voltage. The alternating voltage is derived from a rotation sensor coupled to a toothed wheel and the digital value produced is in binary form. The computer program (Fig. 2) includes a loop which is performed at regular intervals starting from a starting address and switching to a first address if a trigger pulse is present so as to add a constant speed increment data word to an existing speed data word. A step from the starting address to a second address is made if no trigger pulse is present so as to omit the addition step. From the second address a subtraction program is executed to reduce by a fixed fraction the speed data word and then return to the starting address. The invention is intended for use in a vehicle brake anti-skid system. <IMAGE>

Title: Self-aligning thrust bearing
IPC: F16C27/00
Filed: 1979-10-01
Abstract: A self-aligning thrust bearing faces the problem that in flexible bearing structure to prevent scuffing, the flexibility often produces axial misalignment of relatively rotatable members.

The invention might be used in slant axis rotary engines. Self-aligning thrust bearing means (23a, 24a, and 26a; 23b, 24b and 26b; or 123a, 124a and 126a; 123b, 124b and 126b) for first (10 and 11; 111) and second (12; 112) relatively rotable members each includes parts equivalent to the following: a thin bearing member (26a) between adjacent surfaces (28a and 29a) of the relatively rotatable members; a substantially uniformly axially compressible and extensible peripheral sealing member (24a) sealed to a face of the bearing member (26a) and to the surface filling the chamber (30a); and liquid filling the chamber so that axial and cocking loads of either of the relatively rotatable members (10 and 11 or 12) may rock the bearing member (26a) without effective axial displacement.

Patent GB-2083954-A (GB)
Title: Improved power source
IPC: F03G3/00
Filed: 1981-06-05
Abstract: Apparatus for producing power comprises a rotor (10) journalled in a support (1) and comprising cross frames (4). Mass elements (7) are moved along frames (4) by electric motors (5) which rotate lead screws (6). The motors (5) receive power impulses in timed relation to rotation of the rotor via a commutator (8) so that the mass element (7) cross the rotary axis while the respective frame (4) is vertical. The rotor is thus caused to rotate due to the gravity forces acting on the mass elements. The power output from the rotor shaft (2) can be used to drive an electrical generator. <IMAGE>

Patent GB-2102973-A (GB)
Title: Archival storage medium low optical memories
Inventor: NABERHUIS STEVEN L
IPC: G11B7/2575
Filed: 1982-02-24
Abstract: The invention provides a two- layer sandwich for a write-once optical information storage medium. Information is encoded into the device by locally focusing electromagnetic radiation onto an absorber-reflector layer in a desired pattern. As the radiation raises the local temperature, a decomposition layer under the absorber-reflector layer decomposes in the local area. This decomposition creates a bubble under the absorber- reflector layer, which when the medium is cooled leaves a hemispherical radiation scattering center in an otherwise specularly reflecting surface. With dark-field optical techniques, such radiation scattering centers can be used to obtain contrast ratios in excess of several hundred to one.

Title: The decortication of castor beans
Inventor: HUSSEIN ISMAIL HASSAN
IPC: A23N15/10
Filed: 1982-05-08
Abstract: A process developed for the dehulling of castor beans involves treating batches of a known bean size in a pressure vessel with compressed air at super-atmospheric pressure and ambient temperature, with the subsequent release of pressure in an evacuated chamber. The sudden pressure release causes the beans to explode, and the degree of dehulling is a function of the air pressure applied and the bean size tested (8.0 mm, 9.5 mm, 11.2 mm). It is possible to repeat the pressure-vacuum cycle on the same batch of beans.

Title: Hydrorefining and/hydrocracking heavy hydrocarbon feeds
Inventor: FROHN DR WERNER
IPC: C10G45/02
Filed: 1982-12-09
Abstract: The raw hydrocarbon material (1) is separated into a plurality e.g. four component streams identical in number with the number of strands in a multi-strand furnace (F) preceding a catalytic reactor (G), and they are mixed with gases (2) containing hydrogen likewise previously separated into an equal number of streams at temperatures below 520 DEG K. After preheating the mixed raw materials and gases in counter- current with the reaction products leaving the reactor (G), and subsequently heating further in the furnace (F) to reaction temperature, the streams are fed into the reactor (G). After reaction and cooling by heat exchange (in B, C, D, E) with the materials being preheated, the temperature of the reaction mixture is adjusted to enable separation favourable from the energy point of view by heat exchange (in A) with the infeed of raw material before separation of the latter into the component streams. <IMAGE>
