Title: Improvements in signalling and the like rockets
IPC: F42B10/18
Filed: 1960-05-30
Abstract: 916,469. Signal rockets. PAIN & SONS Ltd., JAMES, and MILHOLLAND, P. May 25, 1961 [May 30, 1960], No. 19111/60. Addition to 831,479. Class 9 (2). A modification of the rocket claimed in Claim 1 of the parent Specification consists in slidably mounting the tail sticks 16 on the rocket casing 10, so that they can be retracted within a launching tube and automatically extended on launching. The sticks extend through guides 14 attached to a sheet metal collar 12 mounted on the casing 10 and projections 18 at the forward ends of the sticks act as stops to limit rearward movement of the tail. The inwardly directed vanes 22 made of sheet metal are bent to form a central squaresectioned tube 20. An igniter 24 for the propellant is connected by fuze 26 to the base of the rocket and a loose disc 28, e.g. cardboard, may be used to transmit thrust from the propellant gases to the tail to force it to the expanded position. Specification 916,468 is also referred to.

Title: Improvements in or relating to calling signal responder arrangements
IPC: H04Q1/446
Filed: 1952-07-30
Abstract: 731,446. Electric indicating systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 30, 1952 [Sept. 17, 1951], No. 19319/52. Class 40 (1). [Also in Group XL (c)] A calling signal responder actuated by a call signal of predetermined frequency and adapted for use, e.g. with individual receivers of a multi-station radio communication net, comprises (Fig. 1) a fixed resistance 1, a variable resistance 2, a half-wave rectifier 3, and one winding of a double-wound relay 5 shunted by a condenser 4; all in series across the lowimpedance output terminals a, b of a receiver. A series resonant circuit having low impedance at a predetermined audio frequency and high impedance at other frequencies comprises a variable inductance 7 and a capacitance potentiometer 8, 9; the second winding of the relay and a half-wave rectifier 6 being shunted across condenser 9. The relay armature is mechanically biased to contact I, and any signal on terminals a, b is rectified in aperiodic circuit 1, 2, 3, 4, to hold the relay armature on contact I. A signal at the predetermined call frequency to which the series resonant circuit is tuned is rectified at 6 and energizes the second winding of the relay in opposition to the first while reducing the signal input to the aperiodic circuit energizing the first winding, so that the relay armature breaks contact I and makes contact II to energize a calling alarm or indicator circuit. When the calling frequency lies in the speech band a slow-acting relay may be connected with its double windings in series with the windings of relay 5 and its contacts in series with the contacts thereof, so that both relays must respond to energize the call device, and operation by momentary speech signals of the calling frequency is avoided. The series resonant circuit is replaceable for energization of the second relay winding by a parallel resonant circuit fed from the receiver output through an additional valve and transformer.

Title: Improvements in or relating to change-speed gears
Inventor: TARLTON FRANK HENRY
IPC: F16H3/091
Filed: 1947-07-18
Abstract: 640,240. Change-speed gear; ratchet clutches. ROLLS-ROYCE, Ltd. July 18, 1947, No. 19363. [Class 80(ii)] In a motor-vehicle changespeed gear having a one-way clutch 28 in one ratio (e.g. third) which overruns when a higher ratio (e.g. a direct-drive fourth) is introduced by engaging a dog-clutch 29, automatically or at will, locking of the gear and of its control, such as might occur if the vehicle were to be permitted to attempt to run backwards (e.g. down a hill) with the dog-clutch 29 and one-way clutch 28 both engaged, causing simultaneous engagement of different-ratio geartrains is avoided by arranging for the axial engaging movement of the dog-clutch 29 to move the one-way clutch-members 28 to an inoperative position by actuating a tappet 40 sliding tangentially in the driving member 17 of the oneway clutch. The one-way clutch is of the type having caged rollers 28 which jam between flats on an inner driving member, viz., a third-speed wheel 17 and a cylindrical outer driven member 27 fixed to a freely rotatable sleeve 25 on which the driving wheel 17 is freely mounted and the direct-drive dog-clutch 29 is splined. Engagement of the dog-clutch 29 with the input shaft 10 for direct-drive, renders the one-way clutch inoperative by means of a plunger 42 moving axially with the dogclutch 29, in a hole in the third-speed wheel 17 and having a cam surface 44 acting on the tangential tappet 40 to turn the roller-cage 34 until the one-way clutch rollers 28 occupy an idle position, this movement being limited by a diametrically opposite free or spring-pressed balancing tappet 47. Second and third speeds are introduced by a double synchronized clutch-member 23, which, like the sliding low-reverse wheel 19, is splined on the aligned output shaft 20. The direct-drive dog-clutch 29 may be engaged only for direct-drive or may remain in engagement also in first and second ratios. Specification 640,228 is referred to.

Patent GB-424398-A (GB)
Title: A process for manufacturing coloured cellulose-ester material
IPC: C08K5/00
Filed: 1934-07-02
Abstract: Coloured cellulose ester material is produced by adding to a solution of a cellulose ester in an organic solvent, an ester salt of a leuco vat dyestuff, or an ester salt of another body yielding a coloured compound by acid oxidation previously dissolved in a solvent which is completely miscible with the cellulose ester solution, the mass being coagulated in known manner and the colour developed by acid oxidation during or after coagulation.  The mass may be worked up into films, threads or the like, or it may be applied by printing to another material e.g. a textile fabric, and coagulated thereon.  Suitable solvents for the ester salts are glycol, glycol monoethyl ether, glycol diethyl ether, diethylene-dioxide, and acetone.  In an example, 1 gm. of the acid sulphuric acid ester-salt of leuco-dimethoxydibenzanthrone is dissolved in 20 c.c.s of glycol diethyl ether; this is filtered and mixed with 250 gms. of a solution containing 1 part acetylcellulose, 4 parts acetone, and 1 part of 95 per cent alcohol.  The threads are rinsed and treated in a bath containing sodium nitrite, sulphuric acid and some ammonium vanadate, whereby acetyl cellulose threads of a fast green shade are obtained. In a further example, 1 gm. of the acid sulphuric ester salt of leucodibenzpyrenequinone is dissolved in 20 c.c.s of glycol diethyl ether, and added to 200 gms. of a solution of acetyl cellulose; similarly, a solution of ,5 gm. of the ester salt of leucotetrabromindigo, 10 c.c.s of acetone and 200 gms. of acetyl cellulose solution is prepared; the two mixtures are applied to a cotton fabric in any desired design and the solvent evaporated; on treating in a bath containing sodium nitrite, sulphuric acid and some ammonium vanadate, at 50 DEG  C., yellow and blue relief effects are produced.  Further examples describe the production of films dyed pink and a fast green. Specification 403,049 is referred to.
