Patent GB-2066024-A (GB)
Title: Multiplexed line signalling
IPC: H04J3/24
Filed: 1979-12-18
Abstract: In a fully digital telecommunication system in which speech in PCM (eight-bit word) form and data are handled, it is also necessary to deal with signalling intelligence. To do this, PCM and data are each assembled into blocks (e.g. 1280 bits for PCM and 240 bits for data) in temporary stores (5, 10) each such block when completed is sent out after a header and a suffix are attached to the block. Signalling intelligence is similarly assembled in a temporary store (13) in which it is assembled into a fixed length block and sent out as soon as a PCM block ends. The receiving arrangements are in effect the inverse of the above in that each received block is routed, under control of a header detector (22) which responds to the information in the header identifying the block, into one of a number of stores (24, 25, 26). The intelligence is sent out from these stores at the appropriate bit rate. Error detection facilities (6, 27) are also provided. <IMAGE>

Title: Method and apparatus for removing skin from animal carcasses
IPC: A22B5/16
Filed: 1980-11-27
Abstract: An apparatus and method for removing the torso portion of the skin from the carcass of an animal, such as a hog, includes an overhead support from which a carcass is suspended during the skin removing operation. The skin is first removed from the hind quarters of the carcass and then a cut is made in the skin of the torso completely around the carcass just rearwardly of the fore limbs. A flap forming blade (111) makes a longitudinal cut in the carcass and the longitudinal edge of the skin defined by the longitudinal cut is gripped by revolvable toothed cylinders (71) carried by a revolvable drum (67) to form a flap which is wound about the toothed cylinder. A carcass engaging device (126, 137, 145) holds the carcass against the drum during the flap forming operation. A flexible pressurized movable blade (107) positioned adjacent the drum progressively cuts the skin from the carcass as the drum is revolved. <IMAGE>

Title: Process for the gasification of coal
IPC: C10J3/62
Filed: 1981-01-21
Abstract: Coal particles are dried in a drying zone 10 and are then preheated in a preheater 12 to a temperature just below the pyrolysis temperature. Next the coal is pyrolysed in a retort 20 by contacting it with heat carrying solids and in a non-oxidising atmosphere, to remove substantially all of the tar-forming volatile combustible matter from the coal particles and produce substantially tar-free coal char particles and also volatile vapours and condensible gases. The devolatilised tar-free char particles are then contacted with steam and an oxygen -containing gas in a gasifier 30. The gasification in the gasifier 30 produces a combustible gas which is tar-free can and is ideally suited for combustion, for example to produce combustion gases for driving a gas turbine 54. <IMAGE>

Title: Textile Printing Process
IPC: D06P5/15
Filed: 1981-02-20
Abstract: A "wet-on-wet" process for the resist or discharge printing of synthetic textile materials uses alkali- dischargeable disperse dyestuffs which are free from sulphonic acid and carboxylic acid groups, and free from carboxylic acid ester groups which if hydrolysed would leave carboxylic acid groups attached to the dyestuff molecule, and using sodium or potassium silicate as the alkali. The prints have much better definition than when conventional alkalis are used.

Title: Switching inductive loads
IPC: H03K17/0814
Filed: 1981-03-07
Abstract: A circuit for protecting a switching transistor driving inductive loads such as transformers in switching power supplies includes means such as a two capacitor circuit wherein the capacitors (C3 and C4) are connected in series and are such that their series value limits the rate of voltage rise, the circuit including means whereby when a pre-set voltage level is reached the rate of voltage rise is reduced.

Title: Fuel pumping apparatus
Inventor: PALMER DON CHARLES
IPC: F02M41/14
Filed: 1983-01-12
Abstract: Apparatus for supplying fuel to an internal combustion engine comprises a plunger 10 slidable in a bore 13 which communicates with a chamber 15 from which extends an outlet 16, the communication being by way of a bore 14 of smaller diameter than the bore 13. Slidable in the bore 14 is a second plunger 11. The second plunger 11 engages the first plunger and the two plungers are movable by a cam 21. The plunger 11 has a reduced portion which defines a by-pass between the bore 13 and the chamber 15 and a passage 18 extends from the first bore. The flow of fuel through the passage 18 is halted at some point during the movement of the plungers by the cam. The rate of fuel displacement through the outlet 16 is initially determined by the plunger 11 until the by-pass is opened when the flow of fuel ceases until the passage 18 is closed. The re-established subsequent displacement of fuel is determined by the plunger 10. <IMAGE>

Title: A light-sensitive planographic printing plate precursor
Inventor: NAGASHIMA AKIRA
IPC: G03F7/022
Filed: 1983-05-24
Abstract: The plate is comprised of a support base (1) having one (2) or more (3, 4) light-sensitive layers positioned thereon. The light-sensitive layer or layers comprises an o- quinonediazide compound and an alkali-soluble resin. The concentration of the o-quinonediazide compound in the light-sensitive layer(s) decreases in the direction through the layer(s) towards the support base. Accordingly, the light-sensitive layer(s), prior to exposure to light have increasing solubility in the direction towards the support base. However, after exposure to light, the light-sensitive layer(s) have decreasing solubility in the direction towards the support base. The printing plate aids in preventing the formation of scum and has a high oil-attractive property in the image area. The printing plate precursor has high light- sensitivity and can be developed under a wide range of development conditions. <IMAGE>
