Title: Improvements in or relating to gas burners
IPC: F23D14/04
Filed: 1952-12-22
Abstract: 712,089. Gas burners. SUDA, M. Dec. 22, 1952, No. 32499/52. Class 75 (1) A regulating device for directing the jets of burning gas in a gas ring comprises a closure plate 7 seating on the open top of the gas ring body 1 and a regulating disc 10 rotatably located on the outer surface of the closure plate, the disc having a series of apertures 11 which can be brought into register with a ring of angularly spaced slots 6 in the closure plates. The gas outlet end 12 of each slot 6 is of arcuate shape centred on the centre of the closure plate but the gas inlet end 13 of each slot does not coincide with the outlet end as seen in plan view, Fig. 3. In consequence the gas issuing at different points in the slot is differently inclined to the central axis of the closure plate. Thus the gas at the right hand end of the slot diverges, the gas at the centre E is parallel and the gas at the left hand end converges relative to the central axis of the closure plate. The length of each slot at the outlet end 12 is greater than the length at the inlet end 13. The regulating disc 10 is rotatably mounted on a screw 9 at the centre of the closure plate and is rotated by a handle 8; its position relative to the closure plate determines the direction of the gas jets and when the apertures 11 in the regulating disc approach the ends of the slots the disc also controls the quantity of gas issuing. The apertures 11 can be located completely out of register with the slots 6 to shut off the gas.

Title: Improvements in and relating to aircraft with rotating wings
IPC: B64C27/54
Filed: 1946-11-12
Abstract: 623,582. Helicopters. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and WATSON, K. Nov. 12, 1946, No. 33580. [Class 4] In a rotary-wing aircraft provided with cyclic pitch control mechanism and a rotor hub mounted for tilting in at least one azimuth, the pitch control mechanism and hub are actuated by a common control member so that an angular displacement with respect to the airframe of the control plane, i.e. the tiltable plane with reference to which the blade pitch angle is constant, in at least one azimuth is accompanied by a related and not greater tilt of the hub in the same azimuth and sense. In the construction shown in Figs. 1 and 2, the hub 11 is mounted on a universal joint 40, through which passes a control shaft 35. The latter is connected to three levers 32 disposed as shown in Fig. 2, their outer ends being connected to the blade pitch control arms 23 by links 29. The ratio of the angular tilt of the control plane to the tilt of the hub is given by A.C the expression ---, the quantities A, B, C, D B.D being the lever-arm lengths shown. Collective pitch control is effected by vertical movement of the rod 42. In the embodiment shown in Fig. 3 the rotor blades 54 are carried by a cylindrical member 47 mounted on a fixed mast 45 by a bearing assembly 46 allowing the member to tilt in the longitudinal (XZ) plane. Pitch control of the blades is effected by vertical links 56 connected to a swash-plate 57. For fore-and-aft cyclic pitch control the swashplate is tilted by a hydraulic jack 74 through a double-armed lever 68, 73, link 67, bell-crank 65, and links 63, 64. The link 67 is normally horizontal, while the lever 68, 73 is carried by a bracket 72 fixed to the mast 45, and the arm 68 is attached to a further link 69 parallel to the link 67 and fixed to the tilting member 47. The lengths and disposition of the various links are so selected that movement of the arm 68 not only tilts the member 47 about the bearing 46, thus tilting the hub 49, but also tilts the swashplate 57 relatively to the member 47, in the same direction. Control in the rolling plane is effected by a jack 90 connected to the inner swash plate member 59 by links 87. For collective pitch control the swash-plate is moved vertically by a further jack 85, acting through a bell-crank 83, and a vertical link 82 connected to an arm 81.

Title: Time period switching circuits
IPC: H03K17/60
Filed: 1969-07-04
Abstract: 1,243,436. Time delay switching circuits. WAGNER ELECTRIC CORP. 4 July, 1969 [5 July, 1968], No. 33737/69. Heading H3T. [Also in Division G1] An A.C. timer circuit, for example for supplying water to a wash-basin so long as the hands are present and for a period after their removal, comprises a first switch which when operated by an input signal of predetermined minimum duration operates a second switch, the latter remaining operated for a variable predetermined time after the cessation of the signal. When the hands are present a capacitive detector 18 so reduces the negative pulses from oscillator 22 to a switching circuit 26, 28 that they are insufficient to overcome a positive bias which is a capacitor 34. This bias is developed by current flowing through resistor 36 and the emitter-collection junction of 26 during the positive half-cycles of the supply and is limited in magnitude by Zener breakdown at the base of transistor 28. Accordingly the bias voltage causes the circuit to switch on, shorting the pulse input fed via 58, 60 to a further switch 52, 54, which becomes non- conducting, allowing positive half-cycles of the supply to operate a relay 63 controlling the water supply. The capacitor 40 is charged negtively by the pulses so that if the hands are momentarily removed restoration of switch 26, 28 does not stop the flow of water. If the hands are removed for a sufficient time the oscillator input rises in voltage and makes switch 26, 28 turn off. Capacitor 50 maintains switch 52, 54 off until it has discharged sufficiently to allow the pulses at its input to switch in or, whereupon the relay current is by-passed from the relay coil and the water flow is interrupted.

Title: Process for the production of pigmented artificial fibres
IPC: D01F1/10
Filed: 1954-11-22
Abstract: Pigmented artificial fibres are spun in known manner from spinning solutions or melts with which have been mixed finely-divided pigments which are practically colourless in normal light but which fluoresce in ultra-violet light and are insoluble in the spinning solutions or melts.  The pigments to be used may be 4,41-diacyl - diamino - stilbenes substituted in the 2- and 21-positions with sulphonamide groups of the formula-SO2NRR1, in which R and R1 each represents a hydrogen atom or the same or different alkyl, aralkyl or aryl radical, or in which R and R1 together with the nitrogen atom form a five- or six-membered ring which may be interrupted by an oxygen, a sulphur or an additional nitrogen atom.  The acyl radicals in the 4- and 41-positions may be acetyl, propionyl or benzoyl.  The compounds which may be used include disulphonamides of diaminostilbene compounds of the above type which are derived from diaminostilbenes which have been reacted with cyanuric chloride and thereafter, if necessary, also with ammonia or with primary or secondary amines. Other compounds which may be used are 4,5-diarylimidazolones-2 and 4,5-diarylimidazolthiones-2.  The spinning solution or melt may also contain finely-divided pigment dyestuffs which are coloured in normal light or white pigments such as titanium dioxide, barium sulphate, zinc oxide or zinc sulphide.  The fibres produced may be dyed in known manner.  In an example, sufficient of a dispersion of 130 parts of 4,5-diphenylimidazolone in 200 parts of water to provide 2 per cent of the pigment (based on cellulose) is stirred into a cuprammonium solution of cellulose and the solution is spun.  In a second example, the cuprammonium cellulose spinning solution contains 4,41-diacetylaminostilbene - 2,21 - disulphomorpholide as the fluorescent pigment.  In the third and fourth examples the same pigment is used in conjunction with, respectively, a finely divided azo pigment dyestuff from 2,5-dichloroaniline -->2 - hydroxy - 3 - naphthoic acid anilide, and with an azo pigment dyestuff derived from 5 - chloro - 2 - toluidine-->acetic acidalpha-naphthyl amide, the pigments being added to viscose or cuprammonium cellulose solution. Another azo pigment dyestuff which may be used in conjunction with a fluorescent pigment is that derived from 5-amino-2-benzoylaminohydroquinone diethyl ether-->2-hydroxy-3-naphthoic acid anilide.  In a fifth example the fibres obtained in the first example are dyed with the copper complex compound of the dyestuff obtained by coupling tetrazotized dianisidine with 2-phenylamino-5-naphthol - 7 - sulphonic acid and 1 - naphthol3,8-disulphonic acid. Specification 274,130, [Class 2 (iii)], is referred to.
