Title: Improvements in or relating to the manufacture of crimped yarn of synthetic organic textile fibres
IPC: D02G1/02
Filed: 1957-02-08
Abstract: 815,176. Finishing yarns. HEBERLEIN & CO., A. G. Feb. 8, 1957 [Feb. 15, 1956], No. 4404/57. Class 120(3) In the production of stretch yarn, a multifilamentary yarn of synthetic material e.g. polyamides, polyesters, is temporarily twisted e.g. by 1950-4300 turns per metre, in a direction similar or opposite to the direction of the original twist in the yarn, by means of a false-twisting device. The yarn, in the highly twisted state, is heat treated for a maximum duration of about 3 seconds at a temperature approaching (3‹-30‹C below) the melting point of the yarn material, such that the surface of the filaments undergoes incipient softening and the filaments adhere partially to each other, and then passes through a cooling zone. As shown in Fig. 1, yarn y is fed from a spool 2 through guides 3, feed rolls 4, a heater 5, a cooler 6, a false-twister 12 coupled with a driving motor 7, feed rolls 8, over a tension regulating member 9, traversing guide 10, to a winding device 11. The heater may be a tube comprising a wound electrical heating element or the yarn may pass over and in contact with a metal surface heated by electrical or hot fluid means. The rolls 8 may be driven at a slower peripheral speed than the rolls 4 to produce a 3-15 per cent reduction in the speed of the yarn leaving the false-twister. The cooler 6, Fig. 2, consists of a (glass) tube 13 closed by a glass tube 14 having a capillary yarn exit; a gaseous medium e.g. cool air, is fed through the branch 15 and flows through the tube 13 in the opposite direction to the yarn travel. Single stretch yarns, produced from yarns of opposite residual twist and false-twist, may be doubled.

Abstract: 1,210,215. Telephone exchange equipment. GENERAL ELECTRIC and ENGLISH ELECTRIC COMPANIES Ltd. 30 Jan., 1968 [30 Jan., 1967], No. 4432/67. Heading H4K. Duplexed diplex transmission is employed between registers in a telephone exchange. As shown in Fig. 1 one station has sending keys 5 and 6 with receiving bi-stables 35 and 36 while the other station has sending keys 7 and 8 and receiving bi-stables 37 and 38. The stations are connected by a signal wire 3 and a bus 4 connected to one pole of an A.C. source (not shown) the other pole of which is connected to the earth side of the keys. For negative half cycles of the A.C. source the keys 5 and 7 and associated bi-stables use the wire 3 as a duplex channel, while for positive half cycles of the A.C. source the keys 6 and 8 and associated bi-stables use the wire 3 as a duplex channel. At each station and for each duplex channel resistors such as 15 and 31 provide a duplex bridge the state of which is monitored by the associated bi-stable. The bi-stable will be in a reset condition when no current flows in the bridge resistors or when differential current flows due to operation of the local key. The bi-stable will be set if current flows in series through the bridge due to operation of the distant key or if it flows only through the resistor 15, for example, when both keys 5 and 7 are operated together. If two such signalling systems are used in parallel between registers it provides a 1 out-of 16 code.

Title: Method of and apparatus for electrically treating fluids
IPC: B01D17/06
Filed: 1939-02-10
Abstract: 526,166. Electrostatic separators. LODGECOTTRELL, Ltd. (Research Corporation of New York). Feb. 10, 1939, No. 4460. [Class 72] [Also in Groups XL and III] In apparatus for electrostatically treating fluids for the removal of particles suspended therein, the electrode system comprises a discharge electrode, a non-discharging collecting electrode, and an intermediate non-discharging electrode supported insulatedly, and means for establishing independent electric fields between the discharge electrode and each of the non-discharging electrodes. As applied to the cleaning of gases, one form of apparatus is shown in Fig. 3, and comprises a casing 1 through which the gas flows horizontally. The discharge electrodes consist of rows of thin wires 13<SP>1</SP>, tensioned by weights 21 and suspended from the top of the casing by bars 15, 16, 17 and insulators 18. The collecting electrodes consist of plates 5 supported in upper'and lower stretchers 4, 22 and electrically connected through the casing to earth. The intermediate electrodes consist of spaced bars 6' carried by stretchers 7, 23 and' supported by transverse bars 8 supported on insulators 9. The electrodes are connected in a circuit, which may be such as described in Specifications 411,033, [Group III], and 450,934, [Group XL], so that unidirectional fields are independently established between the electrodes 13<SP>1</SP> and the electrodes 5 and 6<SP>1</SP>, and these may be either simultaneous or alternating. The space between the non- discharging electrodes is preferably subdivided by baffle-plates 34 in electrical connection with the intermediate electrodes. Vibration may be imparted to the plates 5 by a bar 30 having stops engaging the electrodes and also stops 31, 32 engaging the sides of the casing. The movement of the plates brings them into contact with the electrodes 6<SP>1</SP> which are thereby vibrated and momentarily earthed. In a modification, both sets of non-discharging electrodes may be of the rod curtain type. Apparatus for treating liquids, such as for freeing petroleum oil of small amounts of water dispersed therein, is shown in Fig. 10, and comprises a cylindrical casing 130 with inlet 131 and outlet 132, a discharge electrode 134 connected to a source of high tension, and an electrode 137 consisting of rings spaced by struts 139 and supported by a frame 140 from insulators 141. The electrode 137 is energized through a conductor 125' and the casing is earthed. A baffle 143 prevents flow of the oil along the walls of the casing, and the water collects in masses large enough to cause it to settle at the bottom of the apparatus and be drawn off through the pipe 144.

Filed: 1937-02-15
Abstract: 490,391. Cathode-ray tubes. FERNSEH AKT.-GES. Feb. 15, 1937, No. 4504. Convention date, Feb. 14, 1936. [Class 39 (i)] A mosaic electrode 5 scanned by a cathode-ray from a gun G to develop picture signals receives an electron image from a photo-electric cathode 2, and the electrons from the cathode 2 are accelerated to the mosaic 5 for a portion only of the scanning cycle to avoid difficulties arising from rapid movements of objects in the picture thrown on to the cathode 2. The photo-electrons are focused by a coil 6, the effect of which can be varied so that part only of the image is reproduced on the electrode 5 to obtain close-up effects. The photo-electrons are accelerated by a grid 4 to such velocity that secondary emission charges the mosaic elements positively, the secondary electrons being collected by the grid 4 to give a potential across an impedance 10 corresponding to the average picture brightness. The mosaic is double-sided as shown and those electrons from the gun G which are not required to neutralize the positive charges on the mosaic elements cause secondary emission to a ring 7 giving negative image signals across a resistance 8. Specification 442,666 is referred to.

Title: Improvements in or relating to record-card controlled machines
Filed: 1945-02-22
Abstract: 588,492. Type-printing telegraphy. BRITISH TABULATING MACHINE CO., Ltd. (International Business Machines Corporation). Feb. 22, 1945, No. 4517. [Class 40,(iii)] (Also in Group XIX] Apparatus for converting statistical code record into a telegraphic code record comprises means for sensing concurrently corresponding fields of detail and master cards, and a plurality of devices normally controlled selectively by the sensing of code designations on the detail cards ; means are controlled by the sensing of a code designation on a master card concurrently with the sensing of a particular code designation on a detail card, for selecting a device different from the device selected when the code designation on the detail card is sensed alone. The invention is described as a modification of theapparatus described in Specification 566,964. This apparatus is provided with a second sensing mechanism for a master card M.C., so that while successive fields of a detail card D.C. are being sensed by brushes 12 in co-operation with a roller 91, the master card is sensed concurrently by brushes 101 in co-operation with a roller 105. Perforations a in the detail card, which are required to cause the punching of the " TAB " designation in the telegraphic tape, are matched by corresponding perforations b in the master card, and when the two perforations are sensed concurrently the circuit is arranged to cause the punching of both the " TAB ". and " FIGURES " designations in the tape. When, however, a perforation c, in the same index point position on the detail card, is intended to exercise a different control (e.g. when it indicates the 11th month in the date column), nc corresponding perforation is present in the master card, and the sensing of the single perforation causes the puching of a " period ' designation in the tape (which, by convention, is understood to represent the 11th month).
