Title: Apparatus for assembling a mining screen from plastics coated components
IPC: B21F27/10
Filed: 1980-12-29
Granted: 1983-09-07
Abstract: Assembly apparatus for a wear resistant plastic mining screen, preferably one made out of wires formed by extruding urethane around a rigid steel core, includes a feed roll having spaced grooves for receiving elongated profile wires which define the working surface of the screen. A support rod positioning member is mounted at a welding station to frictionally receive a screen support rod on its top side and then be flipped over to position the support rod above the profile wires which pass transversely under it. A welding bar having heated fin portions on its upper and lower sides is then passed between and in contact with the support rod and the profile wires to slightly melt them. The welding bar is then quickly removed and the support rod is quickly moved downwardly against the profile wires and held until the integral joints formed at each intersection are solidified. Additional support rods are welded to the profile wires at spaced intervals until the desired screen length has been reached.

Abstract: PCT No. PCT/GB95/01439 Sec. 371 Date Dec. 4, 1996 Sec. 102(e) Date Dec. 4, 1996 PCT Filed Jun. 19, 1995 PCT Pub. No. WO95/35399 PCT Pub. Date Dec. 28, 1995The fibrillation tendency of solvent-spun fiber can be increased by subjecting the fiber to a treatment which reduces its degree of polymerisation by about 200 units or more. Suitable methods of treatment include severe bleaching, for example application of an aqueous liquor containing 0.1 to 10 percent by weight sodium hypochlorite (as available chlorine) to the fiber followed by steaming. Fiber may be treated in never-dried or previously-dried form. Fiber treated by the process of the invention is useful for example in the manufacture of paper and hydroentangled fabrics. Fiber of increased tendency to fibrillation can be beaten to a Canadian Standard Freeness 400 in the Disintegration Test by 30,000-150,000 disintegrator revolutions and to a Canadian Standard Freeness 200 in the same Test by 50,000-200,000 disintegrator revolutions.

Title: Brake antilocking device for motor vehicle
Inventor: MOCHALOV VALERY VENIAMINOVICH
IPC: B60T/
Filed: 1984-05-04
Granted: 1987-09-23
Abstract: The device contains a computer unit (1) and a brake force adjusting unit (3) controlled by the electromagnetic valves (4,5). The computer unit (1) is connected with these valves (5) and (6) through the power amplifiers (10,11). The two electromagnetic valves are normally open. The first is a pressure reducing valve and the second is a pressure retarding valve. The pressure reducing valve (4) is located in the brake fluid pipe (6) for the adjusting unit (3) between the pressure retarding valve (5) and the brake valve itself (7). The computer unit has a wheel speed into voltage converter, obtaining its values from a speed sensor (2), a differentiator, a shaper of synchronous signals and a two-channel shaper of asynchronous signals. The adjusting unit comprises a source of compressed air (30) with a pipe connection with an acceleration valve (32) and then to the brake cylinder (31) on one side and on the other with the brake itself. Before braking the piston (38) is at its top position, but if the driver brakes using valve (7), pressure can flow from source through valves to space (39), depresssing piston until valve (45) also is depressed, and this allows pressure into space (36), operating the brakes. If there is locking, one of the valves (4) or (5) closes, according to a characteristic curve, stopping pressure going into space so that valve closes and the brakes are released.

An input device (F), which can be a keyboard or keypad, allows commands to be passed on to the controller (D). The visually handicapped person can "read" the teletext information from the output transducer (E) in accordance with commands from the input device (F). The output transducer (E) may comprise a speech synthesiser, a Braille printer, or a Braille pad. @(7pp Dwg.No.1/1)@

Title: Plastic sheets recovery machine
Inventor: SCUDELLARO LORIS
IPC: A01B/
Filed: 1985-11-12
Granted: 1988-03-16
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Title: Salt elimination from greased leather

Filed: 1984-06-07
Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.

Filed: 1981-12-21
Granted: 1987-05-20
Abstract: The invention discloses an elastic lid made of plastic material particularly suited for accumulators for electric traction. The elasticity of the lid is given, not only by the material which is copolymer polypropylene or polyethylene, but also by the hollow shape obtained on the entire surface; the hollowness is turned upwards abd it allows the extension of the poles during the aging process of the accumulator, while preventing the lid from breaking or from detaching itself from the casing. The invention foresees also a moulded circular ring having a tapered section around the refilling opening, it being elastic too, which prevents the spreading of electrolyte drops during the refilling operation and which also acts as a gasket for the cap. According to one form of execution, the ring (5) has a tapered section having its taper turned upwards. A variation is foreseen in which the ring (8) has the taper turned downwards and some steps which make the material lighter in weight.
