IPC: D01D5/20
Filed: 1968-07-05
Abstract: 1,264,327. Varying denier filaments. COURTAULDS Ltd. 4 July, 1969 [5 July, 1968], No. 32128/68. Heading B5B. [Also in Division F2] Thermoplastic filaments have a lengthwise variation of denier imparted thereto by filament-drawing apparatus which comprises :a feed roll 3, a draw roll 4 having a matt circumferential band 9 and a mirror-finish circumferential band 10 on its cylindrical surface, a separator roll 5 having a matt cylindrical surface, and a driven filament deflector arranged to deflect intermittently the filaments from contact with one band into contact with the other band. The filament deflector preferably comprises a cam 11 mounted on a driven shaft 12, the cam surface having two arcuate portions of larger and smaller diameter, and positioned such that when the cam rotates and the larger diameter arc contacts the yarn, the yarn is deflected to the path 1A and on to the matt band 9, the yarn reverting to its original path on to the polished band 10 when the cam has completed a cycle. The yarn wrap round the draw roll 4 and separator roll 5 slips on the matt band 9 but not on the polished band 10, so that it is drawn to a lesser extent when passing round the matt band and a thicker portion of yarn results. In an example, a yarn of polycaproamide filaments is drawn.

Abstract: 1290414 Aircraft instruments BENDIX CORP 17 Nov 1970 [24 Nov 1969] 54627/70 Heading B7W [Also in Division H4] The perspective of a simulated runway (Fig. 1) traced on the screen of a cathode-ray tube in an aircraft head-up display is modified to conform to the actual runway as it appears to the pilot by modifying the deflection and bright-up voltages employed in the production of the display in accordance with signals specifying the location, attitude and altitude of the aircraft. Fig. 2, shows the general nature of the problem to be resolved and Fig. 3 shows the arrangement employed for the latter purpose. As shown (Fig. 3) a signal generator 21 (also Fig. 5, not shown) provides the basic X-Y deflection signals E1, E2 together with shift signals E3 and beams bright-up signals E4 which are required to produce the unmodified runway, centre line and range markers shown in Fig. 1. These signals are then modified in a computer 27 (also Fig. 6. not shown) in accordance with the Ground Track Error derived from ILS receiver 30, the range derived from DME 31, the altitude derived from sensing means 32 and the yaw, pitch and roll derived from sensors 33, 34 and 35 respectively the operation of the computer being controlled by further signals E5 to E8 also derived from signal generator 21. The computer then supplies modified X and Y deflection waveforms E41, E42 respectively to the X and Y deflection coils of the display tube 49 via respective switches 40, 40A controlled by a signal E9 from signal generator 21 such that the deflection signals are passed during the first seven periods t 1  to t 7  (see Fig. 4) of an eight period timing cycle whilst during period t 8  the switches pass the output signals from a known horizon generator 44 controlled by the sensing means 33, 34, 35 to produce the artificial horizon line 5 (Fig. 1). A further switch 40B also controlled by the signal E9 supplies the bright-up signals E4 and bright-up signals from the horizon line generator 44 to the tube control grid 48 in similar manner. To provide the pilot with a sense of speed when landing the sidelines 2, 2A and the centre line 3 are divided into one thousand foot segments.

Abstract: 1336797 Regulating I. C. engines GORKOVSKY AVTOMOBILNY ZAVOD 2 April 1971 8524/71 Heading F1B In an I. C. engine having a main combustion chamber 6 and a precombustion chamber 4, fuel is delivered by a reciprocating pump 1. During starting, idling and low load operation, fuel is supplied only through nozzle 3 into the chamber 4. However, as the load increases the resulting increasing delivery from the pump 1 creates a rise in pressure in pipes 2, 21 during each discharge stroke of the pump, thereby opening a pressure-actuated valve 18 in synchronism with the pump discharge strokes. Thus, pressurized gas from the engine cylinder passes through pipe 17 into a jet pump 9 and a fuel tank 11 in which the fuel level is maintained by a float and needle arrangement 13, 14. The pressurized gas causes fuel to flow along tube 12 and be injected into inlet passage 8 through atomizer 10. Moreover, the loss of pressurized gas from the cylinder through pipe 17, reduces the degree of compression of the remaining mixture. An excess-fuel by-pass port 22 and a spark plug 7 are provided.
