Title: Improvements in dyeing acetate silk
IPC: D06P3/40
Filed: 1925-05-29
Abstract: 257,654. British Dyestuffs Corporation, Ltd., Horsfall, R. S., Lawrie, L. G., Henderson, J. A. R., and Hill, J. May 29, 1925. Azo dyes.-The sulphonic acid groups in the coupling components of acid and direct dyestuffs are converted into sulphonamide groups to yield products suitable for dyeing cellulose acetate. The conversion may be effected with the aid of phosphorus pentachloride and ammonia, or components already containing the sulphonamide groups may be used in making the dyestuffs. In examples, the dyestuffs prepared by coupling diazobenzene with 1-naphthol-3:8-disulphonamide, or with 1 8-naphtha-sultam are used for red or orange shades. According to the Provisional Specification, the dyestuff obtained from Carmoisine WS (B.D.C.) by converting it into the corresponding sulphonamide gives a fast red shade. Specifications 200,873, 202,157, 207,711, 219,349, 224,077, and 243,737 are referred to.

Title: Improvements in braking parachute release mechanism
Inventor: WHALE STANLEY
IPC: B64D17/38
Filed: 1960-04-22
Abstract: 904,388. Stub and socket fastenings. HAWKER AIRCRAFT Ltd. Oct. 24, 1960 [April 22, 1960], No. 14287/60. Class 44. [Also in Group XXXIII] A braking parachute release mechanism for mounting on an aircraft allows the parachute to break away from the aircraft automatically without appreciable drag on the aircraft in the event of accidental streaming, and includes means under the control of the pilot for locking the parachute to the aircraft when the parachute is about to be intentionally streamed and used as a brake, and for simultaneously opening the parachute container doors to initiate such streaming and for returning the mechanism to its unlocked condition when the parachute is no longer required as a brake to allow the parachute to break away from the aircraft under its own drag force. As shown, the mechanism comprises a ball-type connecting member 1 which is attached to the parachute and which has a universal joint connection with a circular shackle 2. The shackle is circumferentially indented at 3 to receive three pivoted claws 4 which are lightly loaded by a spring 5 to engage the shackle but which will release under a light pull on the shackle. To lock the claws into engagement with the shackle a three-legged cam 6 is provided which normally lies clear of the ends 7 of the claws so that the claws are free to pivot about their pivot points 8 but which can be moved into a position in which the legs 9 of the cam lie beneath the claws to prevent their pivoted movement. Rotational movement of the cam 6 is produced by means of an electric or other actuator 10 under the control of the pilot. The cam is fitted with a radially-projecting lever 11 which actuates the parachute container doors by a cable connection. An indicator lamp can be provided which is illuminated when the legs of the cam partially engage the claws to give a visual indication that the actuator is functioning properly.

Title: Improvements relating to television and the like
IPC: H04N3/20
Filed: 1936-05-20
Abstract: 477,038. Television. PHILCO RADIO & TELEVISION CORPORATION. May 20, 1936, No. 14289. Convention date, June 7, 1935. [Class 40 (iii)] A pulse is formed from an input synchronizing signal of one polarity and controls the building up of a voltage of opposite polarity which is combined with the input and then dissipated. The large positive impulse produced by a blocking oscillator V3 on the return stroke is passed through a resistance R3 and a gas-discharge tube RT to a biassing- circuit R, C in the grid circuit of a valve V1. The charge on the condenser C leaks away sufficiently during the scanning of a line to permit the valve to respond to the synchronizing-signal at the end of the line. Specification 468,505 is referred to. The Specification as open to inspection under Sect. 91 comprises also the impulse on the return stroke building up a voltage in a circuit R4, C4 which is applied through a valve V5 to a cathode-ray tube CT. In the absence of this voltage the anode current through a resistance R5 gives rise to a bias sufficient to cut off the cathode ray. This subject-matter does not appear in the Specification as accepted.

Title: Boat propelling and stabilizing apparatus
IPC: B63B39/08
Filed: 1940-09-17
Abstract: 543,904. Propelling and stabilizing ships. RONNING, A. Sept. 17, 1940, No. 14292. [Classes 113 (i) and 114] A propelling installation comprising the power unit 11 and the twin propellers 17, is mounted in trunnions in a caisson 24 detachably mounted in a housing 20 secured within the hull. The propellers take into a recess 23 in the keel K. For steering purposes the lower part of the unit 11 may be rotated by operating the steering-motor 47. One of the power units is arranged well forward and another aft. By inclining the caisson in accordance with the pitching of the vessel by means of a mercury switch initiating the movement of hydraulic cylinders 32, 33, this movement of the ship may be quenched. For the purpose of minimising the roll a pair of the propelling units are mounted amidships off the centre line of the vessel. The rolling motion is reduced by swinging the devices in opposite senses in accordance with the angle of roll. In a modification the propeller units are mounted in the housing so as to be incapable of a tilting motion. The position of the propellers is indicated by a meter actuated by a cam on the shaft connecting them power unit with the propellers.

The stream containing gaseous chlorine may be fed to the reactor at a rate equal to or greater than 18 m./sec., the two incident streams having approximately the same momentum. The chlorine is preferably introduced into the reactor in an amount ranging from the stoichiometric quantity required for the chlorination of the oxides present in the titanium ore to 10% higher than this quantity and the coal which may be used as the reducing agent is preferably introduced in an amount ranging from the stoichiometric quantity required for reduction of the metallic oxides present to 20% higher than this quantity.

Abstract: 1510704 Cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 April 1975 [11 April 1974] 14352/75 Heading H4T [Also in Division G4] In a scanning electron microscope system, Fig. 4 (not shown), including a deflection system generating a television type raster, and in which image distortion is reduced by deducting a third order term from the scanning signal the third order term is generated by a circuit that is unaffected by the frequency of the scanning signal so that a variable frequency scan can be used. A first pair of transistors 20, 21 produce across their collectors a signal proportional to the signal applied to their bases and the current flowing in common collector load transistor 24, i.e. the square of the scanning signal applied at 32. A similar pair of transistors 22, 23 with common transistor 25, produce the cube of the scanning signal and supply it to output operational amplifier 42 from which it is deducted from the orginal signal in an undisclosed manner. In an alternative embodiment, Fig. 3, the third order term is generated by including between input terminal and output amplifier, a voltage-dependent resistor the voltage across which is proportional to I<SP>x</SP> where x is between 0À25 and 0À4.
