Patent GB-2051157-A (GB)
Title: Weight-reducing and Felting of a Cloth
IPC: D06B21/00
Filed: 1980-05-16
Abstract: Weight-reducing and felting a cloth web, by continuously passing the web through a steamer 1 fitted with inlet and outlet seal mechanisms 4 and 5. The cloth is saturated with a treating liquid 42 and is then subjected to a steaming treatment in an upper part of the steamer by being carried in a tensionless state on conveyors 61 and 62. The gap between endless net conveyors 62 and 63 defines a cloth passage a, and nozzles 7 and 8 are arranged to direct liquid jets through the permeable conveyors 62, 63 into the passage a. Hot treatment liquid is sprayed out of nozzles 7 and this causes the moving cloth to follow a zig-zag path, as well as to be vibrated and to be beaten against the conveyors. Hot washing liquid issues through nozzles 8, to perform a preliminary washing step. Conveyor 61 can be replaced by a plurality of guide rolls (12) [Fig. 2] which cause the cloth to follow a zig- zag path, to prevent possible creasing of the cloth. <IMAGE>

Title: Holders for hypodermic syringes
IPC: A61M5/315
Filed: 1980-06-30
Abstract: A holder for a hypodermic syringe particularly for veterinary use has an elongate tubular housing 10 with a tube 22 screwed to one end, the tube 22 forming a cavity for receiving a hypodermic syringe 28 with its needle extending towards the free end of the tube. A sleeve 24 is resiliently mounted at the free end of the tube 22 and covers the needle at all positions of the plunger 32. When the sleeve 24 is pushed against the animal patient, the sleeve retracts and the end of the needle passes through the end of the sleeve and punctures the patient's skin. A push rod 12 axially slidable within the housing 10 can then be operated by a pressable head 18 so that the plunger 32 of the syringe 28 is moved forward and the animal is injected. <IMAGE>

Patent GB-2085870-A (GB)
Title: Improved process for production of ethyl acrylate
IPC: C07C67/54
Filed: 1980-10-17
Abstract: In a process for the continuous production of ethyl acrylate from ethylene and acrylic acid in the presence of sulfuric acid, impurities are removed from the reaction system by passing minor portions of sulfuric acid residue from the process through a wiped-film evaporator whose initial sections are heated to a specific temperature range and whose last or withdrawal section(s) are cooled to a specific temperature range. This treatment prevents foaming of the used sulfuric acid residue. The treated sulfuric acid residue in the wiped-film evaporator is withdrawn from the reaction system. An additional aspect of this process is the passing of at least 50 weight percent of the ethyl acrylate product residue from the finishing distillation tower into the wiped-film evaporator at the same time that the sulfuric acid residue is being treated, whereby additional ethyl acrylate product and acrylic acid starting material is recovered and a residue containing polymerization initiators, which can cause undesirable polymerized product, is removed from the reaction system.

Patent GB-2099083-A (GB)
Title: Apparatus for raising and lowering a ramp on a floating bridge
IPC: E01D15/20
Filed: 1981-05-26
Abstract: Floating bridges or ferry vessels are provided with raisable and lowerable ramps for the formation of a connection to the bank. If the vehicles or vessels do not have their own power supply, it is necessary to provide a manually operated hydraulic piston pump for pivoting the ramps. With a heavy load on the ramp a high pressure is created in the hydraulic circuit, which may lead to unpleasant results. In order to avoid this, it is proposed to form the hydraulic cylinder (8) as a balanced cylinder with a piston (23) with equal surface areas, to arrange a non-return valve (21) and a pressure-limiting valve (20) directly on the high-pressure side of the hydraulic cylinder and to design the hydraulic-oil reservoir (14) as a closed pressure tank. In this way it is possible to avoid excessively high pressures in the hydraulic circuit, which could lead to leakages and to the escape of hydraulic fluid or even to bursting of the hydraulic-oil reservoir. <IMAGE>

Title: Determining the concentration of a gas fraction in multiple gas mixtures
IPC: G01N29/22
Filed: 1982-03-11
Abstract: First of all, water vapour is removed at 10 from a test gas mixture until the dew-point of the mixture falls below a prescribed value. The component, which is to be determined, is then removed, by means of a selective absorber 30, from a partial stream, which is split off at 14 from the remaining gas mixture, and ultrasonic signals are passed through both partial streams, in two measuring cells 20, 32 including electro-acoustic transducers, which cells are thermally coupled in a close manner, under the same pressure. After conversion into an equivalent voltage value, and appropriate processing at 44, the phase- difference, measured between the two ultrasonic signals, is used as a measure of the concentration of the gas fraction to be determined. <IMAGE>

Title: Hydraulic boosters for vehicle braking systems
IPC: B60T13/14
Filed: 1982-04-22
Abstract: An hydraulic booster has an input member (4), a boost piston (3), an output member (6), and connections (10, 11) to a source of pressure (67) and a fluid reservoir (68). Force applied to the input member (4) is transmitted to the output member (6) and augmented by the boost piston (3) in response to pressurisation of a boost chamber (7) controlled by valve (8) operated by pressure generated on initial movement of the input member (4) within the boost piston. An auxiliary chamber (13) is defined between the boost piston (3) and the output member (6). Initially to take up lost-motion in the system, the auxiliary chamber (13) is supplied with fluid from the source to advance the output member (6) relative to the boost piston (3) through a distance determined by a stop (14). Subsequently, the output member (6) and the boost piston (3) move together in response to pressurisation of the boost chamber (7). The area of the boost piston (3) on which the auxiliary pressure acts is greater than or equal to the effective area of the boost piston (3). The boost chamber (7) and the auxiliary chamber (13) may then be in permanent communication. <IMAGE>
