Patent GB-2255861-A (GB)
Title: A device for picking up sound waves propagating in water
Inventor: BROCHARD CLAUDE
IPC: G01V1/20
Filed: 1979-10-24
Abstract: A chain of elongate components (10, 20) are connected end-to-end. Each component (e.g. 10) comprises a sheath (1) closed at its ends and filled with a dielectric liquid (e.g. kerosene). Sound detectors are located in the liquid as are electric conductors for conveying signals therefrom. The confronting ends 11, 22 of two adjacent components carry electric connectors 12, 19 and at least one of these ends also carries a valve (14, 24) which releases the dielectric liquid from inside the sheath into the interstices between the confronting end surfaces 11, 22. A bleed screw can be used to ensure no air remains. This arrangement minimises pressure differentials around the join between two adjacent elongate components and facilitates use of the chain at great depths. <IMAGE>

Title: Method and apparatus for shielding a stream of metal
IPC: B22D11/106
Filed: 1979-12-17
Abstract: Molten metal is poured from a ladle or, preferably, tundish into the mould of a continuous casting machine. Shielding gas is distributed from a distributor (10) surrounding the stream of metal as it falls from the tundish into the mould. The distributor (10) has a heat-resistant gas-permeable generally annular member (12) of ceramic material received in a casing which covers part only of the surface of the member (12). Contact between the ceramic member (12) and the inner surface of the casing is such that there is substantially no free gas passage therebetween. The casing has diametrically opposed gas inlets from which shielding gas passes through the ceramic member (12) issuing from the exposed faces thereof. <IMAGE>

Title: Direct-viewing storage target for a cathode ray tube
IPC: H01J29/18
Filed: 1980-01-18
Abstract: A bistable storage target for a direct view storage cathode ray tube includes a transparent insulating support member 64 having a conductive mesh electrode, 32b on one surface, an insulating material 37b covering the mesh electrode except for exposed areas of the mesh electrode, with the insulating material extending part way into the mesh apertures into engagement with the support member surface thereby insulating the mesh apertures and reducing their size, and islands of, storage dielectric, phosphor material disposed in the insulated apertures for storing information written thereon by a writing beam of electrons so that the dielectric islands are isolated from the mesh electrode. Insulating material 37b may be a nonphosphor, to give neon zero background luminance; a non-storing phosphor to permit colour write- through; or a storage phosphor to give colour contrast. As shown, a conductive layer 62 may be interposed between the faceplate 56b and the insulator 64 to permit selective erasure of information. <IMAGE>

Patent GB-2058516-A (GB)
Title: Telephone set
IPC: H04M1/02
Filed: 1980-08-21
Abstract: There is disclosed a compact telephone instrument with a telescoping operation. A first housing (A) has a conventional telephone receiver located within a hollow recess thereof. This housing (A) is removably secured to a bottom housing (B) which contains a dialer assembly (11). A series of guide mechanisms (e.g. 21, 22) are formed in both housings and are used to accommodate a third housing (C) containing a telephone transmitter. The third housing (C) is slidably mounted within the receiver and dialer housings to enable on-hook and off- hook operations by sliding and extending outwardly for off-hook operation and by pushing the housing inward for on-hook operation. The transmitter housing is accurately guided between the receiver and dialer housings by the guide mechanisms to ensure accurate and reliable operation relatively independent of the nature of the force exerted by a user on the transmitter housing when operating the instrument. The movement of the transmitter housing between the on and off hook positions automatically activates a hook switch arrangement by means of tabs which are permanently secured on slide members associated with the transmitter housing and which tabs actuate leaf spring switches located on a component board positioned between the dialer and receiver housings. <IMAGE>
Patent GB-2061041-A (GB)
Title: Arrangements for data timing recovery from distorted signals for use in adaptive modems with multi-level coding
IPC: H04L25/03
Filed: 1980-09-04
Abstract: The submission makes use of the fact that where an adaptive equaliser (APS) is incorporated in a modem, some sort of training sequence is employed prior to the transmission of the data message. This training sequence usually incorporates a block of pseudo-random data (DIS) transmitted at the basic symbol rate to provide the equaliser (APS) with a relatively less distorted signal to operate on. During the training period both threshold-derived timing (TCTRL) and Nyquist-derived timing (NTRL) are produced. The Nyquist-derived timing (NTRL) is then phase-shifted (APS) to correspond to the threshold derived timing (TCTRL) which is valid during the training period. The phase shift (APS) is then fixed so that, when multi-level coding is introduced valid timing can still be obtained from the Nyquist-derived timing signal (NTRL). In addition in the event of transmission interruptions the invention allows timing recovery without the need for a new training cycle.

Patent GB-2076250-A (GB)
Title: Mechanical X-ray scanning
IPC: A61B6/06
Filed: 1981-01-22
Abstract: Apparatus for obtaining CT scans employs a rotating unit operative to produce a scanning pencil beam of X-ray radiant energy by use of a mechanical scanning device consisting of a first collimator which shapes radiation emitted from an X-ray source into a fan- shaped beam of X-rays, and a second collimator comprising a disc- shaped chopper wheel which is rotated through the fan-shaped beam. A single pencil beam is produced and caused to scan through an angle, sufficiently great to embrace a cross section of a body being examined, onto at least one elongate detector forming a portion of the rotating unit and located on the side of the body opposite to the X- ray source and mechanical scanning device. The system can also be used to generate its own localization images and to perform digital radiography on those images and, because of the relative rotation feature, can be employed in this mode of to obtain anterior-posterior, lateral or oblique images at any desired angle. <IMAGE>

Patent GB-2095933-A (GB)
Title: Circuit arrangements
IPC: H03J5/02
Filed: 1981-04-01
Abstract: A radio receiver 5 has a control input 6 responsive to digital control signals to tune the receiver to a particular frequency and produces digital output signals on a line 10 in dependence on its frequency at any particular time. A memory 12 stores digital codes corresponding to the valves of each of a number of predetermined frequencies to which the receiver is to be tuned. A digital comparator 18 compares the digital output signals and any particular one of the digital codes from the memory 12 and produces a digital error signal dependent on the difference (if any). The digital error signal is fed to the receiver on line 6. A keyboard 14 enables any desired frequency to be keyed in, and causes the memory 12 to output the corresponding code. The invention is applicable to frequency control in signal generators, transmitters. The number of frequency steps required to produce the output frequency is controlled by the digital control signal via a cascaded chain of up-down counters. <IMAGE>

Title: Electromagnetically-actuated clutch and brake units
Inventor: NESBIT JOHN ROCHESTER
IPC: F16D67/06
Filed: 1981-11-05
Abstract: An electrically actuated combined clutch and brake unit 1, for use on lathes, vending machines and other applications, comprising two portions 3 and 5. First portion 5 is fixedly mounted concentrically about a drive shaft 33, and includes actuating coils 7 and 11. Attached to the end of the drive shaft 33 is a clutch member 19. Mounted on the adjacent end of a driven shaft 35 for rotation therewith is second portion 5, comprising annular friction pads 23 and 25 mounted concentrically about the driven shaft 35. In use, energisation of the inner coil 7 generates an electromagnetic field which causes the corresponding friction pad 23 to contact clutch member 19, connecting drive shaft 33 and driven shaft 35 together. Energisation of the outer coil 11 causes the outer friction pad 25 to contact frictional surface 13 of the coil 11, so slowing or stopping the driven shaft. The concentric arrangement of the actuating coils prevents energisation of one coil from unintentionally actuating the wrong friction pad, probably by the provision of a null point in the electromagnetic fields in the plane of the boundary between the coils. <IMAGE>
