Title: Improvements in the shrinking of cellulose derivative textile materials
IPC: D06M13/127
Filed: 1946-10-15
Abstract: Textile materials comprising fibres having a basis of an organic derivative of cellulose are subjected to the shrinking action of diethyl ketone.  The extensibility of the fibres is increased. Staple fibres, continuous filaments, yarns, or fabrics, may be treated.  The cellulose derivative may be cellulose acetate, propionate, butyrate, aceto-stearate, or other ester, or ethyl or benzyl cellulose or other cellulose ether. Stretched or unstretched yarns may be treated, particularly yarns of cellulose acetate which have been stretched in steam.  The diethyl ketone may be used alone or in a mixture with another shrinking agent, e.g. methylene chloride.  The treatment may be carried out at 60-100 DEG  C., the lower temperatures being more suitable for unstretched or lightly stretched materials, and temperatures above 80 DEG  C. being preferred for yarns which have been stretched by seven or more times their original length.  The treatment may reduce the lustre of unstretched and lightly stretched yarns.  After the treatment, the materials may be cooled to room temperature and then freed from the diethyl ketone by washing with petrol.  Specifications 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, 443,773, and 488,794 are referred to.

Title: Improvements relating to electrical control system
IPC: G05D3/16
Filed: 1954-10-27
Abstract: 782,277. Electrical positional control systems. BRISTOL CO. Oct. 27, 1954 [Nov. 5, 1953], No. 30998/54. Class 40 (1). The invention relates to positional control systems of the automatically-balanced bridgetype in which movement of a control member 23 upsets the balance of an A.C. bridge 21-30- 32-22-33-38-36-31, the output of which is amplified in a triode 45 and through an amplifier-relay 27 drives the balancing motor 25 to adjust the potentiometer 22 and simultaneously adjust the load 26, e.g. an aircraft control surface. To render the motor inoperative on the occurrence of certain faults in the system, resistors 36, 38 are arranged in the bridge circuit at a position remote from the potentiometers 21-22 so that the points X, Y at the outer ends of these resistors remain at substantially equal potentials during normal operation. When a fault such as an open circuit or short circuit occurs in any of the bridge resistors or their connecting conductors 34-35-37, a potential appears across the points X-Y, and is applied over a transformer 43 and rectifier 60, to render a normally blocked diode 65 conducting and thus short circuit the normal signal input to the triode 45 to stop the motor 25. A ground on the slide wire contact lead 41 also effectively short circuits any normal bridge output signal. Should an open circuit occur on either of the slide wire leads 40-41 the resultant decrease in voltage drop across a resistor 66 increases the potential applied by the H.T. battery 51 to the diode 65 which conducts and again short circuits the normal signal input to the triode 45. Reference has been directed by the Comptroller to Specification 747,555.

Abstract: 820,747. Baling-presses. SPERRY RAND. CORPORATION. Oct. 15, 1956 [March 29, 1956], No. 31294/56. Class 94(1). In a travelling pick-up baler in which hay is compressed by a plunger 13 reciprocating in a chamber 11, the hay is fed by a rotary pick-up device 20 and co-operating corrugated drum 26 on to a platform 25 which extends laterally from an opening 12 in a side wall of the chamber, and is moved over the platform into the chamber by fingers 40, 41 and 42 which depend from a reciprocable tubular bar 43 and are arranged to project through a slot 33<SP>1</SP> in the bottom wall 33 of a housing enclosing the bar and its operating mechanism. The bar is fitted at its rear end with a shaft 45 having rollers 46, 46<SP>1</SP> at its ends running in curved tracks 48, 48<SP>1</SP> secured to the side walls 34 and 35 of the housing, see Figs. 3 and 7, and encloses a piston 54 whose rod 53 is encircled by a compression spring 59 and pivoted at its end to one of the links of an endless chain 66 running around sprockets 69, 70. The chain is driven continuously in synchronism with the plunger 13 so that on its forward stroke the bar 43 is first inclined downwardly to cause the fingers 40-42 to move downwardly and forwardly into engagement with the hay, then horizontally to cause the fingers to sweep the hay over the platform into the chamber 11 in front of the advancing plunger, and finally upwardly so that the fingers 40, 41 are withdrawn through the slot 33<SP>1</SP> and a slot 11<SP>1</SP> in the top of the chamber 11 and make a return stroke above the wall 33. The fingers 42 project through the slot 33<SP>1</SP> on their return stroke, but are pivoted on the shaft 45 and swingable anticlockwise against the action of a spring 52 so that they ride over the hay. Variations in the quantity, condition or density of the hay fed on to the platform 25 are compensated for by the spring 59 which yields if a predetermined resistance to movement of the fingers is exceeded.

Abstract: 209,404. Technicolor Motion Picture Corporation, (Assignees of Comstock, D. F.). Jan. 8, 1923, [Convention date]. Drawings to Specification. Kinematograph picture film; films, stripping; colour photography.-Kinematograph films are mounted, after exposure through the back, on an inextensible backing for development. The backing may consist of a thin metal strip, for example of brass or steel, which may be plated with copper or a copper alloy, and may be coated with lacquer to improve adhesion. The film and backing may be united by an intermediate layer of binding material, the cementing being effected by feeding them through pressure rollers and then heating at about 125‹ F. for about thirty minutes. The cement may consist of amyl acetate with a little camphor, or the lacquer and cement, for example a suitable lacquer and amyl acetate, may be mixed and applied together. In forming relief matrix films, the images may be printed in uniform relation to the perforations by which they are subsequently to be registered. In a subtractive two-colour process, two relief films with a metal backing, representing the red and green, may be used to print successivelv the red and green images on a blank film by imbibition, accurate registration being obtained by the metal backing. The Specification as open to inspection under Sect. 91 (3) (a) comprises also kinematograph films formed of a plurality of strips cemented' together, latent images being formed on one of the strips, which are joined before development, corresponding perforations thereon being aligned. Exposure may be effected after the film is joined to the backing and the combined film and backing strip may be perforated as a unit. The film may be confined, in this case, to the space between the perforations in the backing. Where backed relief films are used' to print the colour images on a blank film, the latter may have a metal backing strip. Two relief films may also be coloured, mordanted to prevent migration of the colour, and cemented face to face, giving a subtractive two colour film. The films are joined to the backings by a less tenacious cement such as shellac where easy stripping is required. This subject-matter does not appear in the Specification as accepted.
