Title: Flame retardant cable
Inventor: SMITH TIMOTHY STEPHEN
IPC: H01B7/295
Filed: 1986-02-27
Abstract: A multiconductor electric cable comprises a bundle of electrical conductors each of which is electrically insulated from the or each other conductor by means only of an extruded insulating coating of a polymeric material that leaves an electrically insulating residue on combustion. The insulating coating preferably has an inner layer 1 that exhibits good electrical resistance and an outer layer 2 that is relatively highly filled e.g. cross-linked polyethylene or copolyethylene propylene with up to 60 wt % of silica or hydrated alumina and optionally Sb2O5. The insulated conductors are enclosed by one or more wrapped mineral tapes 3,5 e.g. of mica-silicone resin tape or Mg silicate impregnated tape and the bundle and tape are enclosed in a cable jacket e.g. of a highly filled copolymer of ethylene. Optionally a screen is provided. It is possible to form cables of this type that exhibit good circuit and signal integrity performance and which are also of small diameter. <IMAGE>

Title: Improvements relating to tensioning devices for use with chain conveyors
Inventor: WAZNIAC JAN C
IPC: B65G23/44
Filed: 1986-04-28
Abstract: It is necessary in chain type conveyors to keep the chain under an optimum tension and preventing sudden surges while at the same time ensuring that the chain stripper/cleaner bar is kept in close proximity to the return wheels. The bearing housing 7 is capable of sliding movement relative to conveyor structure by means of longitudinal bolts 9 having compressible springs 11 ensleeved over them to attain initial chain tension. Tension is maintained by a pawl and ratchet arrangement 15,17 connected to the bolts 9 by a plate 13. An L-shaped plate 21,22 is attached to the bearing housing 7 via plate 10 and extends through the side of the conveyor return structure. The plate 22 carries a combined chain-stripper/groove cleaner plate at its end adjacent the grooved wheels 5. <IMAGE>

Title: Pyridinylpiperazine derivatives
IPC: C07D471/04
Filed: 1986-05-02
Abstract: Disubstituted 1,4-piperazinyl derivatives are disclosed wherein one substituent is a bicyclic fused-ring furo-, pyrrolo-, cyclopentadieno-, or thieno-pyridine heterocyclic system and the second substituent is an alkylene chain attached to cyclic imide heterocycles, such as azospiro[4.5]decanediones, dialkylglutarimides, thiazolidinediones, succinimides, and morpholine-2,6-diones; or a fluorobenzylic carbinol moiety.

Title: Device to select needles in knitting machines
Inventor: DVORAK MILOS
IPC: D04B15/78
Filed: 1986-06-24
Abstract: A device to select needles by means of the jacks in a circular knitting machine for the production of socks and the like goods, comprise a set of swingably mounted and spring-loaded selecting levers (3) placed opposite to the jack butts and associated with electro-magnets controlled by the control device of the machine, while the selecting levers (3) are provided with profiles (33) for radially pressing-in the jack butts and are swung by said jacks against the action of the springs to enable selection by the magnets. The invention enables reliable operation at higher speeds of knitting by providing ahead of the profile (33) cams (100, 110) with edges for axial displacement of the jacks and thus to move the selecting levers (3) to the electro- magnets (5). Levers raised by the cam (100) through the jacks are selectively retained in inoperative position or released to disengage the jacks from a raising cam (102). <IMAGE>

Title: Anti-rebound hammer head
Inventor: GONZALEZ JULIAN GONZALEZ
IPC: B25D1/00
Filed: 1987-02-20
Abstract: An anti-rebound hammer head (1) comprises two body parts (6) each partly hollow and of metallic material and each having at one end an impact face (8) and at the opposite end a sealing face. The sealing faces are welded together so that the hollows communicate to form a single hollow 2, preferably extending more than two thirds of the distance between the impact faces, and containing anti-rebound filling material (3). A neck portion (7) of the parts adjacent the sealing surfaces define an annular recess into which is moulded an annular part (5) of a handle (4). A threaded plug (11) extends into the recess and thus into the handle to stiffen the connection and prevent relative rotation. The construction of the hammer-head is simple and by increasing the size of the hollow (2), compared with known systems, sufficient filling material (3) can be incorporated to allow the impact faces of the hammer to be made of metallic material. The sealing faces may be shaped or bevelled to determine interconnection in one relative angular position only. <IMAGE>

A monostable 4 is intended to pass a signal at a substantially constant level to the speaker 7 irrespective of the strength of the received signal, i.e. the distance between receiver and transmitter. <IMAGE>
Patent GB-2210870-A (GB)
Title: Superconducting substances
Inventor: ASPDEN R HAROLD
IPC: C04B35/45
Filed: 1987-10-12
Abstract: Based on the finding that a phonon resonance effect occurs in electrically conducting substances when the inertial reaction of a molecule is close to an integral multiple of 102 atomic mass units on the carbon 12 atomic mass scale, permitting electron migration with negligible energy loss, the invention provides a substance having such a molecular composition to within 1% and requires that at least (0.7)< eta > of the molecules should comprise identical combinations of the isotopes of 2+n elements, where n is an integer. An example for which n is unity is the composition La2CuO4, the copper ingredient of which has been enriched in the copper 65 isotope to ensure that more than 70% of the molecules comprise two La 139 isotope atoms plus one Cu 65 isotope atom plus four atoms of the oxygen 16 isotope.

Patent GB-2211012-A (GB)
Title: Edge-illuminated display aid
Inventor: PILKINGTON DESMOND
IPC: G02B6/00
Filed: 1988-10-10
Abstract: An illuminated display aid of slim or shallow construction eliminates the space requirement of the customary light-box by employing a lateral light source (10), 62 which shines into an edge (2), 69 of a display element (1), 63 of transparent material, the light after internal reflection being scattered through a main face (3), 72 to back-light a translucent item 67 for display purposes. Uniformity of back-lighting is achieved by a surface treatment (eg abrasion) of at least one main face of the display element to produce the scattering, which treatment is intentionally increased in severity or optical density with increasing distance from the light source (10), 62. The display aid can be employed to present illuminated panels of many shapes and sizes, for displaying thereon photographic transparencies or displaying thereover translucent tubular garments such as stockings and tights. The aid may also be used to illuminate drawing boards and road signs. The display element may be made of opal acrylic and the surface treatment may be stepped, stepless, moulded or painted with spots instead of being abraded. UV light may be employed as an alternative to tungsten filament, halogen or gas discharge lamps. <IMAGE>

Title: Data transfer apparatus for multi - track tapes
Inventor: MATTHEWS JAN GREGORY
IPC: G06F3/06
Filed: 1990-05-10
Abstract: A controller 12 for controlling the transfer of data between a host system and a tape having a plurality of addressable tracks. The controller on receiving from the host a track select signal passes the signal on to the tape drive 14 to allow recording on the selected track e.g. 1. Once this track has been filled the tape drive sends an end of track signal EOT to the controller to direct the head to address the interleaved track 5 associated with the filled track, at the same time reversing the direction of the tape so that recording takes place in the opposite direction. Once this track has been filled the controller passes on to the host the end of track signal received from the tape drive. On playback, the host accesses a standard track (1 to 4) searching for a specific item. The controller passes this request to the tape drive which accesses first the track addressed by the host e.g. 1 then the interleaved track 5 until the desired item is found. This operation is transparent to the host which believes itself to be accessing the requested track 1 continuously. <IMAGE>
