Patent GB-959768-A (GB)
Title: Fabric treating process and apparatus
IPC: D06B7/08
Filed: 1960-06-07
Abstract: Elastic diapers comprise a multi-layer sheet of loosely woven fabric having a common selvedge along two parallel edges for all layers and a non-ravelable construction formed along the other two edges, the warp and weft yarns for all said layers having been shrunk in an unrestricted manner to produce a relatively high degree of elasticity in the diaper in all directions.  The elastic diaper material may comprise a multi-layer sheet of loosely woven fabric that has been shrunk in all directions in an unrestricted manner by continuously feeding a strip of fabric in a free loop form through a shrinking fluid bath at a rate sufficient to prevent any shrinking in the bath and supporting the strip so as to allow unrestricted shrinking in all directions when out of the bath (see Division D1).  The multi-layer sheet may have selvedges common to all layers at each longitudinal edge and the yarns of adjacent layers are interwoven at equally spaced intervals longitudinally of the sheet to form bars of unravelable fabric; the diapers may be formed by severing this sheet midway of each of the bars.

Title: Method for adjusting the motion of quartz-controlled clocks
Inventor: JINDRAK VIKTOR
IPC: G04R40/02
Filed: 1960-06-08
Abstract: 936,835. Automatic frequency control systems. ELEKTROCAS NARODNI PODNIK. June 8, 1960, No. 20037/60. Class 40 (5). A quartz clock is adjusted by varying a D.C. regulator voltage applied to the oscillator crystal (GT cut). The oscillator frequency # is first converted to pulses of recurrence frequency f rich in harmonics and compared with a transmitted standard frequency F=nf in a radio receiver tuned to F, until any beats on its tuning indicator are eliminated by adjusting a voltage regulator controlling the D.C. voltage on the oscillator crystal and hence its frequency. Alternatively a phase discriminator may automatically control the crystal voltage. The clock synchronous motor 9 is driven through a frequency divider 7 from the oscillator. The oscillator may be thermostatically controlled. The clock may be portable and use transistors.

Filed: 1944-12-08
Abstract: 628,242. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Dec. 8, 1944, No. 20055/48. Divided out of 628,174, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 7, 1945. [Class 40 (iv)] One of a plurality of electrical conditions indicative of the category to which a circuit belongs is applied to a control circuit and each of a second plurality of conditions is applied in turn to the control circuit which responds when the two applied conditions have a predetermined relationship. The control circuit may be associated with an operator's circuit, Fig. 16, for determination of the class of service of a calling subscriber. The operation of the subscriber's cut-off relay places a potential, characteristic of the class of service to which he is entitled, on the T-wire, which is connected by the operation of key SIK to the grid of the tube V1. Relay DR energizes to complete the driving circuit for a switch which connects up a number of potentials in turn to the grid of the tube V2. When the two grids have the same potential a gas-filled tube GV breaks down, the switch is stopped by a relay ER and the class of the calling party is shown on an indicator. The control circuit may also be part of a registercontroller as described in Specification 628,174, and adapted to respond when the register is connected either to an inter-exchange trunk or a call-box subscriber. Specifications 628,176 and 628,179 also are referred to.

Title: Improvements in and relating to cathode ray tubes
IPC: H01J29/62
Filed: 1935-02-13
Abstract: 452,125. Cathode-ray tubes. NICOLL, F. H., 17, The Drive, Ickenham, near Uxbridge, Middlesex. Feb. 13, 1935, No. 20237/36. Divided out of 452,012. [Class 39 (i)] In a circuit for television &c. transmission including a cathode-ray tube with an electrode system for focusing an electron beam on to a transmitting screen 11 and with means for deflecting the beam to scan the screen 11 to neutralize an electrostatic image of the picture to be transmitted, the two focusing electrodes 8, 9 nearest the screen 11 form an electron lens with the electrode 8 nearer the cathode 4 at a higher positive potential than the electrode 9. The tube shown has a cathode shield 5, an accelerator 6 and a modulating electrode 7, in addition to the anodes 8, 9 as described in Specification 431,327 and the electrodes are supplied from tappings on a potentiometer 12, 13. The anode 9 may be a silvering on the wall of the tube, and may be at the same potential as the accelerator 6 so that fluctuations in the currents to the electrodes 6, 9 neutralize one another and the size of the potentiometer and smoothing condensers can be reduced. The low potential on the anode 9 reduces secondary emission from the screen 11 and prevents secondary and cold-emission electrons from the anode 8 from reaching the screen. The screen may be a photo-electric mosaic and may be photoelectric on the side opposite to that scanned by the ray as described in Specification 419,452. Electrodes not focusing the ray, for example, a grid, may be placed in front of the screen 11. The Provisional Specification describes also subject-matter included in Specification 452,012.

Title: Disc clutches
IPC: F16D21/04
Filed: 1933-07-19
Abstract: 410,350. Friction clutches. HERBERT, SIR A., LLOYD, A. H., and HARRISON, H. T., c/o Herbert Ltd., Canal Road, Edgwick, Coventry. July 19, 1933, No. 20365. [Class 80 (ii).] In a multi-plate clutch for connecting a member 16<B> to a shaft 13, operating levers 18B coacting with the presser plate 17<B> are pivotally mounted on radial pins 29B on a sleeve 19<B> which is splined on the shaft 13 and is urged towards a shaft collar 22<B>, accommodated partially within the pressure plate, by springs 20, which latter thus take up the clutch reaction. The levers are actuated by radial pins 32B on a collar 11 splined on the sleeve 19B, the pins coacting with the inclined ends 33<B> of the levers, which latter have flat parts 34B whereby the clutch can remain engaged without any reaction being taken by the collar 11. The collar 22B lies on a non-splined portion of the shaft and has internal grooves 24B corresponding to the splines, whereby, after being threaded into position, the collar may be twisted to bring the grooves out of alignment with the splines, spring plunger 25B being provided to lock the collar in its twisted position. As shown, one set of springs 20 and one actuating collar 11 serve for a pair of oppositely-arranged clutches A, B, arranged for selective operation. One of the keys 30 which afford the splined connection between the collar 11 and the sleeves 19<A>, 19B is axially fixed in the sleeve 19B and extends beyond the end of the other sleeve 19A when either clutch is engaged, so as to indicate by the amount of its projection the spacing of the sleeves 19A, 19B and thus the amount of wear that has occurred in the engaged clutch.

Title: Preparation of printing relief images and photographic elements therefor
IPC: C08F2/48
Filed: 1953-05-01
Abstract: 741,470. Photographic process for preparing printing relief images. DU PONT DE NEMOURS & CO., E. I. May 1, 1953 [Dec. 19, 1952], No. 20708/54. Divided out of 741,441. Addition to 741,294. Drawings to Specification. Class 98 (2). The process of the parent Specification, in which a layer of an ethylenically unsaturated photopolymerizable composition containing a catalyst for such photopolymerization carried on a permanent metal support is exposed through a half-tone or line transparency to polymerize the exposed portion to the insoluble state and subsequently treated to remove unexposed areas and thereby leave a relief image, is modified by effecting the exposure so as to produce a tapered relief image the projection of the sides of which form in the case of a half-tone printing relief an inner angle with the support between 50 and 90 degrees and in the case of a line-printing relief a corresponding inner angle between 63.4 and 76 degrees. Such relief images have enhanced strength and minimize building up of ink on the printing areas; and the exposure therefor may be effected by a broad light source or an oblique light source arranged around the periphery of the area to be exposed. In Example I an aluminium base-plate is first provided with the antihalation anchor layer of Example IV of the parent Specification and then a clear anchor layer comprising methyl methacrylate, isobutyl methacrylate, polymeric methyl methacrylate, monomeric polyethyleneglycol dimethacrylate, benzoin and 1,11-azodicyclo-hexanecarbonitrile, which mixture is photopolymerized to form such anchor layer. Spacing strips are then placed at the edges of the layer and a photopolymerizable syrup comprising benzoin methyl ether, styrene and polypropylene glycol/maleate/phthalate is flowed thereon; a half-tone film negative mounted on a glass plate is lowered on to the syrup, excess of which is allowed to flow out until the negative rests on the spacing strips, and the assembly is exposed for 10 minutes while rotating on a turntable to three mercury vapour lamps, one above the assembly and the other two on opposite sides with their beam axes directed at 45 degrees to the assembly. After exposure the negative is removed and unpolymerized material washed away with an ethyl acetate/ethanol mixture to leave a relief image with printing areas having sides sloping at angles of about 58 degrees to the base. A somewhat corresponding procedure using a line negative and directed to the production of a printing relief of high dimensional fidelity to the negative is described in Example II. Seven further specific examples and descriptive matter usually referring to the original Specification 741,441 are concerned with other variations. Specification 566,795 also is referred to.
