Title: Improved process and apparatus for the production of a yarn with capillary thread loops from endless synthetic filaments
IPC: D02G1/16
Filed: 1956-12-14
Abstract: 825,237. Finishing yarns. KUNSTSEIDEN A.G., and ONDERZOEKINGSINSTITUUT. RESEARCH N.V. Dec. 14, 1956 [March 12, 1956], No. 38295/56. Class 120(3) In a process for forming looped or bulked yarn from a "pretwisted assembly" of endless artificial or synthetic filaments, twisted yarn is exposed in a channel to a stream of pressure gas directed transversely to the longitudinal direction of the yarn and meets the yarn secantially against the direction of twist in such manner that the yarn is momentarily loosened and uniform loops are formed at regular intervals in the individual filaments, the yarn being turned aside immediately at the end of the channel transversely out of the stream of gas flowing conjointly therewith. The yarn is tensioned, and the effect of the subsequent destressing thereof increased by a component of the gas stream flowing against the direction of travel of the yarn. In the apparatus shown in Fig. 1, an "assembly of twisted filaments" 1 is led from a spool 2 through a guide 3 at a constant speed by clamping rollers 4 to an air-blast channel apparatus and through a guide channel 5 into which compressed air is injected through an inlet 6; bulked yarn is led under tension by rollers 8, through a guide 9, rod 10 and traverse guide 11 to a take-up spool 12. As shown in Figs. 2 and 3, a smooth-surfaced channel 5 is rounded off at inlet 15 and outlet 16 ends and inlet 6 (of the same diameter as channel 5) delivers air, in the direction of arrow 7, so as to discharge eccentrically into channel 5 and/or the yarn, travelling in the direction of arrow 13, is so angularly guided as to ensure the secantial meeting. The channel 5 may widen in the direction of yarn travel e.g. an insert may be fitted in the inlet end to reduce the diameter thereof, so that the gas velocity is reduced at the outlet.

Title: Improvements in or relating to electrical bridge networks

IPC: G01R17/10
Filed: 1963-10-01
Abstract: 1,110,943. Measuring electrically; measuring bridge circuits. SANGAMO WESTON Ltd. Dec. 31, 1964 [Oct. 1, 1963], No. 38656/63. Headings G1N and G1U. In a Wheatstone bridge network including a variable-dependent resistance, linearity of the output of the bridge compared with values of the variable is enhanced by means for increasing the bridge current when said resistance increases, and vice versa. As shown, Fig. 3, the current supplied to a bridge network BN, which includes a platinum resistance thermometer R in one arm thereof, is varied by a current controller CC in dependence on a signal from a compensation feedback network CN which senses the voltage developed across the resistance thermometer R. In Fig. 4 (not shown) two transistors (T2, T3) having their bases commoned, form the current controller CC, bridge resistors B, C each being connected in the emitter circuit of one of the said transistors. The compensation feedback network CN comprises a third transistor (T1) whose base receives a signal derived from the voltage developed across R, and whose collector is coupled to the bases of the current controller transistors (T2, T3). In a further embodiment, Fig. 5, a constant current I p  divides into two components, the bridge supply current I which passes through an amplifier U, and a by-pass current Is which passes through a second amplifier W. The tendency of the bridge current I to fall when resistance R increases in value is off-set by the action of amplifier W, which reduces Is; since I p  is maintained constant, I is increased. Transistorized exemplary circuits embodying this arrangement are depicted in Figs. 6 and 7 (not shown).

Abstract: 1479700 Automatic control of moulding FEDERAL MOGUL CORP 10 Sept 1974 [26 Sept 1973 23 May 1974] 39528/74 Heading G3N A moulding press is automatically opened under computer control when the cure of the material being moulded is calculated to be complete in dependence upon the temperature of the mould cavity. In an example, a digital computer stores data relating to a mould arrangement and to a rubber or synthetic elastomer compound being moulded, so that it can calculate the required cure time in accorcance with the Arrhenius equation relating the logarithm of the cure time to the moulding temperature. In operation a timer starts when the mould is closed, and the instantaneous temperature of the interior of the mould is continuously supplied to the computer which repeatedly calculates and recalculates the required cure time. When the actual elapsed time reaches the instantaneous calculated time, the computer causes the mould to be opened automatically. The computer also ensures that the mould temperature is kept within a desired range by proportional control of heaters. A further embodiment is described in which a series of moulds are controlled independently and simultaneously by the computer.
