Patent GB-2081917-A (GB)
Title: Photographic reversal processing
IPC: G03C8/12
Filed: 1980-08-12
Abstract: A photographic reversal process is provided wherein a compound which reacts with oxidised electron transfer agent (ETA) to form a dye or other visible product or intermediate and which is associated with a negative- working silver halide emulsion layer reacts to only a very limited extent with the oxidised ETA formed on development of the imagewise exposed silver halide owing to the presence of a competing oxidisable substance with which the oxidised ETA preferentially reacts so that only a very limited amount of dye or other visible product is formed by the reaction and wherein the concentration of the competing oxidisable substance is lowered and/or additional oxidised ETA is formed at least in the areas of the remaining silver halide, so that on reversal development enough oxidised ETA becomes available in these areas to oxidise the remaining competing oxidisable substance and to react with said compound and form a dye image or other image. Preferably said dye diffuses into a separable image-receiving layer.

Title: Electrical Circuits
IPC: G11C19/14
Filed: 1980-08-29
Abstract: Noise, produced by fast decay of m.m.f. from saturation to remanence in a magnetic logic component, e.g. a laddic, is prevented from causing a spurious output by employing a coupling circuit between two such components. in the circuit, the output winding 11 of a first component 1 is connected via pulse shaping means D, C, R1 to the input of an amplifier A whose output is connected to a reset winding 13 of the second component. This arrangement is such that the rate of rise of the m.m.f. generated in the said reset winding is limited by the inductance of the reset winding, and the rate of fall of the said m.m.f. is limited by the rate of decay of the input applied to the amplifier by the pulse shaping means. <IMAGE>

Title: A system for enciphering and deciphering digital signals
IPC: H04L9/08
Filed: 1981-06-19
Abstract: A transmitter for enciphering information bearing RF signals in digital form has a data enciphering circuit 12 which utilizes a first key common to all receivers. The first key is charged by a key generator 14 of the transmitter, which sends an individual message to each receiver, each message being itself enciphered in a second key which is peculiar to only one receiver or small group of receivers and which message includes a change of the first key. The key generator 14 is controlled by an initiate new key circuit 20. At each receiver there is a comparator responsive to the correct address in a key change message which will thereafter permit the deciphering of the key change message in the key peculiar to that particular receiver or small group of receivers. The new first key is then used at the receiver to decipher subsequent information bearing messages. <IMAGE>

Title: Cryogenic apparatus
IPC: F25B9/14
Filed: 1981-07-16
Abstract: The displacer of a cryogenic refrigerator comprises two sections, with one displacer section being arranged to vary the volume of a first chamber (6) as the displacer undergoes reciprocating motion, and the other displacer section being arranged to vary the volume of a second chamber (8) during the same motion. The first and second chambers, which serve as working chambers from the standpoint of achieving refrigeration, are connected by first and second heat exchangers (14,16) and first and second thermal regenerators (10,12) respectively and a flow control means (4) to high (30) and low (32) pressure sources of refrigerant fluid. The flow control means comprises a slide valve member (74) which is movable by the displacer and coacts therewith to control movement of refrigerant into and out of the first and second working chambers and a third chamber (19) as their volumes change with movement of the displacer. <IMAGE>

Title: Guided missile
Inventor: RANSOM RICHARD SUTTON
IPC: F42B12/60
Filed: 1981-10-23
Abstract: A tactical guided missile 10 has a load comprising a plurality of guided sub-missiles 27A-F and 37A-F. The sub-missiles can be deployed in flight of the missile by driving them out of an open forward end of a thin walled skin tube 11 by means of a propulsive charge 20 acting on a piston 19. The use of a plurality of guided projectiles instead of a single projectile makes a lower accuracy of missile guidance tolerable. The sub-missile may be located in the annular space between an inner-hexagonal support cylinder and the tube 11, with their noses tilted radially outwards to assist dispersion. The remainder of the space contains foam segments which act as sabots and also constitute a nose portion 30.

Patent GB-814111-A (GB)
Abstract: 814,111. Applying insulating tape to conductors. OKONITE CO. Jan. 18, 1957 [March 23, 1956], No. 1906/57. Class 109 Insulating tape is helically applied to a conductor by apparatus which comprises a drum-carrier rotatable coaxially about the conductor having mounted thereon one or more drums each having a slit peripheral wall and means for supporting one or more coils of tape within the drum, tape guiding means on each drum and tape-snubbing means co-operating with the outer face of the peripheral wall of each drum. As shown, three drums 6 are adjustably mounted on a rotatable spider 2 by a shaft 12 and nut 14.

Patent GB-2121180-A (GB)
Title: Catalytic combustible-gas detectors
Inventor: EDGINGTON BRUCE ROBERT
IPC: G01N27/16
Filed: 1982-05-01
Abstract: Catalytic combustible-gas detectors are subject to poisoning or obstruction by certain non-volatile residues - such as lead or silicone vapours, so reducing the sensitivity of the device. A detector pellet having much greater resistance to catalyst poisoning, especially by silicones, incorporates within the pellet a significant proportion of a colloidal silica carrier material (particle size 0.001 to 1.0 ???m). Such a detector comprises a heatable wire filament (10) embedded in a pellet formed overall of an oxidation catalyst and a porous non-catalytic inert carrier, of colloidal silica. Preferably the pellet is in two main parts; an inner part (11) is a mixture of catalyst and carrier, while an outer part (12) is carrier alone. <IMAGE>

Title: Improved shock-absorbing wheel suspension assembly
Inventor: MULHOLLAND LAWRENCE K
IPC: B60G3/28
Filed: 1982-06-01
Abstract: In a shock-absorbing wheel suspension assembly comprising a rigid yoke 12 having a generally upstanding neck 38 and a pair of downwardly diverging hollow tubular sleeves 46, 48 connected to the lower end of the neck, a pair of flexible resilient lever support arms 16, 18 have their upper ends extending into the sleeves, the lower ends of which are angled towards each other and are secured in the central hub of a wheel disposed therebetween. The neck 38 is connected to an upwardly extending stem 14, in turn connectable to the underside of the body of a vehicle or the like. During normal transport of the vehicle and rotation of the wheel, temporary displacements of the wheel occur, due to road shocks which are dampened and minimized, since the middle portions of the arms are torsionally strained and cause the upper portions of the arms to undergo considerable torque. Thus, the assembly provides effective shock absorbtion through a simple, durable arrangement of components.   <IMAGE>

IPC: H01H19/03
Filed: 1982-10-08
Abstract: A multistage rotary switch has at least one detent switch position 16 and a further non-detent switch position at each ends of the turning range, and a rotor 6, with an adjusting shaft 7, is always moved back automatically from an end position into the adjacent last detent switch position by the action of a reset spring 10. The ends 11 of the spring 10 each cooperate with an associated stop bolt 14, 15 and while a first bolt, eg 14, is acting on the spring 10 the second bolt, eg 15, cooperates with a stop edge 25 which defines a non-detent switch position. Axially extending end portions 12 of the reset spring 10 are engaged in a slot 13 whose length is almost equal to the spacing of the end portions 12. This arrangement is said to allow a compact construction. <IMAGE>
