Title: Improvements in methods for the production of foils, sheets, plates and profiled articles from fleeces
IPC: B29B17/00
Filed: 1960-06-30
Abstract: 918,704. Agglutinated fibrous materials; laminates and laminating. MICIAN, R., and TRACHTOR, J. June 30, 1960 [July 3, 1959], No. 23001/60. Class 140. A method for the continuous production of foils, sheets and plates by pressing or rolling an endless fleece produced from cord waste fibres and threads produced by grinding used tyres, comprises continuously treating the waste in scutching or carding machines to form a coherent self-supporting endless fleece which, after saturation with a binder, is, without the use of moulds, cut and pressed or without cutting continuously rolled to the final product. The binder may be applied, as a liquid, by spraying or misting, or, as a powder, by dusting. As shown (Fig. 1), cord waste is fed through pipe 1 into carding of scutching machine 2 where it is treated to form fleece 3 which is conveyed by endless conveyer 4 through chamber 5 where it is sprayed or misted with binder through nozzles 6, excess vapours being drawn off through pipe 7, and then through chamber 8 where it is dried by passage through a highfrequency electromagnetic field produced between electrodes 9, excess vapours being drawn off through pipe 10. The dried fleece is then conveyed by conveyer 11 to cutting table 15 where lengths are cut by guillotine 13 and deposited on to sheet metal supports 14. A number of cut pieces 3 each on a metal support 14 are pressed in press 16. In a further embodiment (Fig. 2) a plurality of laps of fleece 21, produced according to the invention, are each sprayed, misted or dusted with binder from applicators 25 and assembled in superposed layers to form a multiple fleece 28 which is then passed through chamber 30 comprising a high-frequency electromagnetic field produced between electrodes 31, whereby the binder, if liquid, is dried and if a powder is melted. Surface layers 34 and 36 which may be of plastic foil, paper, metal foil or woven material are then applied and the assembly is pressed between belts 38-39 of a pressing conveyer.

Title: Improvements in mine roof supports
Inventor: KNIGHTS RICHARD NORTHAM
IPC: E21D23/00
Filed: 1948-09-01
Abstract: 658,998. Hydraulic jacks. DOWTY EQUIPMENT, Ltd. Sept. 1, 1948, Nos. 23081/48 and 14470/49. [Class 78 (iii)] [Also in Groups X and XXIX] A mine roof support comprises two sets of props each consisting of at least two props 11, 11a and 12, 12a. The props in each set are rigidly connected by cross-tubes 15 and the sets are pivotally interconnected by links 17. Roof bars 18, 19 and floor bars 20, 21 are pinjointed to the props. When the props of one set are loosened, they are advanced by means of a hydraulic jack 28. The props may be operated hydraulically. The supply of pressure fluid to the props and to the jack 28 may be controlled by a valve box 30, Fig. 3. With the props in the full line position, pressure-fluid is supplied by a pump 39 from a reservoir 38 into a valve chamber 42. The fluid passes through a valve 43, passage 45 and pipe 37 to the jack 28, and through a non-return valve 51 and pipe 33 to the props 11, 11a. The props 12, 12a are closed to the reservoir so that they also support the desired roof load. As the jack 28 is in its contracted position and the piston cannot move inwards, pressure builds up in the passage 45 causing a piston 54 to move up and open a non- return valve 50, to open the props 12, 12a to the reservoir. The pressure in the chamber 42 also builds up and acts on a plunger 73 which through a spring-operated, dead-centre mechanism 65, 68 moves the valve 43 down to open the passage 45 to the reservoir and supply fluid through passage 44 and pipe 36 to expand the jack, and move the props 12, 12a to the position shown dotted. A similar cycle then takes place, pressure building up in the passage 44 and the chamber 42, to move the props 11, 11a. Relief valves 55, 56 are set to limit a maximum roof load of 50 tons for each pair of props. The pipes to the prop also include non- return valves 58 and relief valves 59 which ensure that the props support a roof load of 1 ton, when loosened. Manually operated valves may be provided for relieving the props. According to the first Provisional Specification the props may be provided with springs which act against the fluid pressure.

Title: Telephone system
IPC: H04M9/08
Filed: 1977-06-03
Abstract: 1524756 Loudspeaking telephones L P KARLSSON 3 June 1977 [8 June 1976] 23793/77 Heading H4R In an echo suppressor for a loudspeaking telephone system signals in the go and return channels are fed, in p.c.m. form, to the inputs of a comparator 10 via respective dividers, 14A, 14B, and maximum value selectors, 15A, 15B. The comparator compares its inputs and controls the divider on the input having the highest signal to divide the signal by a lower factor than the divider on the input having the smallest signal, and also interrupts sound transmission to the loudspeaker which would otherwise be fed with the smallest signal. As shown in Fig. 1 the signals from the microphones of interconnected sets A and B, if not already in p.c.m. form, are fed through a p.c.m. coder to a sign eliminating circuit 13 feeding a divider 14, which can divide either by 1 or by 8, using a nil shift or a three place shift of the binary coded signal. The divided signal is fed to a maximum value circuit, comprising an up down counter (25) Fig. 2 (not shown) and a comparator (24) which compares the input signal with the counter output and gates clock pulses into the counter so that the counter counts up toward the input signal value, at a clock rate of 250 kHz, when the input is above the counter output and counts down toward the input signal, at a clock rate of 2À5 kHz, when the counter output is above the input signal value. The resulting peak detected signal values are fed to a comparator 10 which produces a "1" on line 16A when the signal from detector 15A is the larger and a"1" on line 16B when the signal from detector 15B is the larger. The comparator outputs are fed to a delay circuit, Fig. 3 (not shown) comprising a 4 stage counter (36), fed at a clock frequency of 6 kHz, and a bi-stable circuit (37), arranged to provide a delay of 16 x 6 kHz clock pulses after a change in comparator 10 output before the appropriate change occurs at the bistable circuit of the delay 18. The bi-stable outputs are arranged to switch the divider circuits 14 to provide divide by 1 on the divider connected to the channel carrying the highest signal and divide by 8 on the other channel, and to open a switch 22 in the channel carrying the lowest signal to prevent the signal reaching the respective loudspeaker.
