Title: Methods of and apparatus for crimping,bulking or texturising filaments
IPC: D02G1/00
Filed: 1961-11-24
Abstract: 969,648. Finishing yarns. MONSANTO CO. Nov. 24, 1961 [Dec. 12,1960(2)], No. 42168/61. Heading D1F. A thermoplastic filament is crimped or bulked by passing it through a treating zone under tension and uniformly heating one side of the filament to a stress-relief temperature while simultaneously maintaining e.g. by cooling, the opposite side at a lower temperature. Heating may be effected by continuously directing a heated gas e.g. air at a temperature of 60-1100‹F., at successive contiguous points on the filament, or by passing the filament through a non-wetting liquid such as molten solder. The heat-treated filament may be collected under the same tension and thereafter relaxed to develop therein a helex which coils alternately in opposite directions. As shown in Fig. 1, mono- or multifilament yarn 11 is advanced from a bobbin 12, past a tensioning device 14, one turn around a driven "heat-sink" roll 17, thence to a take-up roll 18. A nozzle 21 directs heated air from a source 22 on to the yarn so that the exposed side(s) of the individual filamen (s) is/are heated to or near the softening or melting point of the material thereof: since the yarn is under tension on roll 17 it is flattened and spread so that, in general, the individual filament(s) is/are exposed to the hot air and in contact with roll 17. The main flow of heated air is in a direction parallel to the yarn path, Fig. 3 (not shown). The air temperature, spacing of nozzle from roll, hot air supply temperature, yarn speed, yarn tension and/or roll temperature may be adjusted or controlled to determine and regulate the bulking effects. The roll 17, Fig. 4, is secured to driving shaft 26 and positioned adjacent to a manifold 27 which has air intake and exhaust openings. 28 and 29 and communicating passages 33 and 34 through which a stream of cooling air is directed by fan blades (not shown) integral with the roll. Specification 969, 649 is referred to.

Abstract: 1441449 Ammonium polyphosphates GEWERKSCHAFT VICTOR CHEMISCHE WERKE 11 Sept 1973 [16 Sept 1972 31 March 1973] 42747/73 Heading C1A Crystalline water-insoluble ammonium polyphosphates are prepared by condensing a melt of water-soluble ammonium phosphate by mixing at 200-400‹ C. in a stream of undilated gaseous ammonia until at least 90% of the polyphosphate is water-insoluble (defined as less than 5% dissolved in water at 25‹ C. in 30 minutes). Wet process phosphoric acid may be treated with ammonia and concentrated to give the water-soluble ammonium phosphate. The process may be continuous or batch. The condensation reaction may take from 30 to 150 minutes and may be carried out in the presence of recycled ammonium polyphosphate to keep the reaction mixture dry and crumbly. The product may be size-reduced at 100-200‹ C. and may be washed with 15-25% ammoniacal water.

Abstract: 1,163,551. Limiting arrangements. APPLIED DYNAMICS Inc. 26 Sept., 1966 [8 Oct., 1965], No. 42795/66. Heading H3T. In a stabilized amplifier which includes a first amplifier stage, comprising an amplifier for non-zero frequencies in parallel with a stabilizer channel consisting of a chopper modulator, high gain amplifier, and demodulator for amplifying zero frequency at high gain, and further D.C. amplifier stages from the output of which negative feedback is taken to the input of the first amplifier stage, the signal level is monitored at a point within the amplifier and a limiting negative feedback channel is connected whenever the signal excursions exceed predetermined values. A circuit is also provided to give an overload indication whenever the signal excursions exceed second, smaller, predetermined values. Fig. 1 shows an amplifier including an A.C. coupled input circuit feeding one input of a differential amplifier 4 to the other input of which is applied the output of stabilizer channel 6. The output of amplifier 4 feeds, via emitter follower Q5, two cascaded Darlington pairs consisting of transistors Q6, Q7 and Q10, Q11 which feed the output stage 14 with feedback overall provided by impedance Z. Limiting feedback is provided by transistors Q8 and Q9 arranged to conduct when the signal at the collector of Q7 goes respectively above or below predetermined limiting levels to instantaneously complete a feedback circuit back to the amplifier input via diodes X4, X5, or X1, X2. In order to provide an indication of overload, transistors Q13 and Q14 are connected to monitor the current taken by transistor Q11. Transistors Q13 and Q14 are normally conductive to hold the potential on line 15 at near zero. If the signal excursion exceeds predetermined limits, smaller than those required to cause the limiting feedback circuit 10 to operate, either transistor Q13 or transistor Q14 will be cut off, depending on the direction of overload, to cause neon lamp DS1 to light and a signal to be fed out over line OL, e.g. to control a computer overload circuit as described in Specification 1,130,567.

Abstract: 1,004,062. Valves. WAGNER ELECTRIC CORPORATION. Nov. 5, 1963 [April 23, 1963], No. 43617/63. Heading F2V. A pair of identical valves in tandem control, the fluid flow from separate reservoirs 4, 10 to separate brake chambers 8, 13; the reservoirs are fed by a common pump 15. Upon manually depressing a piston 56 the force is transmitted through a spring 53 to a piston 43, and through a link 57 and spring 53a to a piston 43a, both pistons moving against springs 47, 47a until piston extensions 46, 46a abut valve closure members 36, 36a, respectively, to close outlet ports 30, 30a from exhaust ports 23 and 35a. Further downward movement of the pistons 43, 43a disengages the valve members 36, 36a from seats 32, 32a in opposition to springs 42, 42a to interconnect the inlet ports 29, 29a with the outlet ports 30, 30a. The fluid pressure in the outlet ports reacts on its associated piston 43, 43a, the total reaction force being applied to the piston 56 via springs 53, 53a and causing the valves to " lap " when it equals the manual input to this piston; the springs 53, 53a enable the operator to " feel " the braking effort or application. When the manual force is removed the parts return to the positions shown and fluid from the brake chambers is exhausted through ports 23, 35a as well as additional ports 52, 52a. If one valve fails, the other is operated in the usual way without any increased stroke of piston 56, but the reaction force is halved.

A pulse length discriminator responsive to pulses lying within predetermined upper and lower limits, comprises delay lines 12A/12B, 15, gates 13, 14, 17 and a subtractor 18 connected substantially as shown. When employed as an anticlutter device in a radar system having a transmitted pulse length of T, the lines 12A/12B and 15 are arranged to have delays of T, 0À8T, and T respectively. An output from 14 exists only for a pulse longer than the lower pulse length limit 0À8T. The subtracting network 18 provides an output 19 only when an output exists from 14 and not 13 i.e. the input pulse at 10 is within the specified length limits (0À8T-1À8T). An input pulse of length T is thus reduced to 0À2T.
