Title: Improvements relating to the production of slivers of staple fibres from tows of continuous filaments
IPC: D01G1/04
Filed: 1946-04-24
Abstract: 606,093. Stapling and preparing slivers from continuous filaments. MACKIE & SONS, Ltd., J., and MACKIE, J. P. April 24, 1946, No. 12406. [Classes 120(i) and 120(iii)] [Also in Group XXIV] Tows of continuous filaments of artificial silk are cut and the severed fibres delivered in successive bunches end on to a carding machine, which forms them into - slivers. In one form of apparatus for carrying out the invention, Fig. 1, continuous tows 28 are fed 'through rollers 25, 26 to a carding machine feed apron 12 comprised of slats spaced apart. Cutters 41, prefer- .ably rotary discs, are mounted above the apron 12 and are arranged to descend between the slats at suitable intervals, such as would give six inch lengths of fibre, in order to cut the tows, two tows being, preferably, cut by each cutter. The cutters 41 pass through a slot in a presser plate 42, which is arranged to descend with the cutters 41 on to the tows 28 to hold them during severing. The presser plate 42 is carried by arms 43 which slide through slots in brackets 44, 45 projecting from a beam 33 and presses on the tows under its own weight. In a modification, the presser plate may be spring-urged downwards. The beam 33 supports the cutters 41 and their driving motor 35 and is slidable in slotted guides 34, which may be moved to and fro along the carding machine frame 11 by heart-shaped cams 50. Eccentrics 60, at each end of a shaft 62, effect raising and lowering of the beam 33 through straps 59 and rods 57 (one only of each being shown). To obtain lowering of the cutters 41 during the forward movement of the beam 33 only, so that the beam may be returned to starting position with the cutters 41 raised, a clutch is provided to transmit motion to the shaft 62 at intervals, (see Group XXIV). In a modification, the clutch may be dispensed with and a crank motion used. Another form of apparatus has a separate feed apron upon which the tows are cut and the bunches of cut fibres are passed on to the ordinary feed apron of a carding engine. In another form, the tows are cut at the nip of a pair of rollers, one of which is equipped with cutting blades and the bundles of fibres are overlapped on a carding engine feed apron. In another modification, Fig. 10, tows 28 are delivered between rollers 122. 123 to the surface of a pinned drum 124 which is slotted at intervals corresponding with the length of staple fibre desired. Cutter discs 41b enter the slots to sever the tows.

Title: Television signal synchronising-pulse separator
IPC: H04N5/08
Filed: 1957-04-18
Abstract: 809,396. Television. STANDARD TELEPHONES & CABLES Ltd. April 18, 1957 [May 25, 1956], No. 12717/57. Class 40 (3). The anode voltage and, consequently, the cut-off characteristic, of a valve V2 which operates as a limiter to separate synchronizing signals from combined video and synchronizing signals derived from the final video stage V1 and supplied with positively-going synchronizing signals to the grid of V2, is varied directly as the amplitude of the combined signal input to the latter valve by including the contrast control potentiometer R2 in a potential dividing network R5, R6 from a point P on which the anode voltage for V2 is derived. This arrangement ensures that synchronizing signals free from video components are derived in the anode circuit of V2 for all levels of the input signal thereto. Instead of having the contrast control potentiometer R2 in the video stage V1 it may, alternatively, be employed to control either the H.F. or I.F. amplifier stages. In arrangements employing screen-grid or pentode valves for V2, the combined signals to be separated may be supplied to the second grid and the first grid utilized to effect noise limiting.

Abstract: 1,206,145. Producing looped fabrics. R. J. COREY. 12 Sept., 1967, No. 12772/70. Divided out of 1,206,144. Headings D1C and D1K. A simulated knitted fabric has a loop construction comprising upright and inverted loops 123a, 124a in which the loops of one course pass behind and in front of the legs of the preceding and succeeding courses, the loops of each course being separated by a straight portion 135 as shown in Fig. 1 or by a stepped portion 135a as shown in Fig. 8. The number of steps between the loops may be larger or smaller depending on the amount of pliability it is desired to achieve. The fabric can be tubular as disclosed in Specification 1,206,144 or it can be flat and can be shaped and reinforced in various areas. It has runresistant characteristics since the breakage of a loop does not permit succeeding to preceding loops to become disengaged. The fabric can be produced in a flat condition by using a bobbin 150 which is intertwined about a number of parallel bars and through the loops contained on the bars as shown in Fig. 18. Alternatively a tubular fabric can be produced by using a succession of bars as shown in Fig. 19.

Filed: 1936-05-08
Abstract: 476,676. Refrigerating. ANDREWS, H. I., and HERBERT, T. M. May 8, 1936, No. 13033. [Class 29] Absorption systems. -A reversing system having an evaporator 2, 2a of such large capacity that it is only partially emptied during each evaporation - absorption period is controlled by a thermostat 12 influenced by the cooling action of the evaporator so that when the temperature in the storage chamber 1 falls below that at which the goods are to be maintained a period of generation and condensation is initiated to replenish the evaporator. The apparatus is particularly applicable to railway vans, in which case the generator-absorber 7 is heated by steam supplied from a locomotive through a pipe 8 or by electricity supplied from an axle-driven dynamo. The thermostat 12 controls the steam valve 13 or a switch of the electric heater. Preferably the thermostat also initiates an evaporation period when the temperature of the storage space rises above that desired for the goods. In addition, a thermostat may be used to control a valve 24 between the condenser 5 and the evaporator to permit or interrupt evaporation when the heat supply is not available, as when the vehicle is uncoupled from the train, to conserve the store of refrigerant in the evaporator as much as possible. The heating periods may also be terminated by devices influenced by the temperature or pressure in the generator-absorber or in the condenser.
