Title: Improvements relating to Electric Arc-incandescent Lamps.
Inventor: GARBARINI ANDRE
IPC: H05B31/00
Filed: 1919-03-18
Abstract: 129,259. Garbarini, A. July 3, 1918, [Convention date]. Arc lamps.-An arc is rotated electro-magnetically between an annular and a central electrode both of highly-refractory metals, such as tungsten, molybdenum, uranium alloys, iridium, and osmium. Direct or continuous current may be used; with continuous current, the outer electrode is the negative one. The central electrode may be a metal cap T, Fig. 6, mechanically made or electro-deposited on a stud of graphite, carbon, or like material conducting electricity but a poor conductor of heat. The cap may vary in form; it may be dovetailed to the stud as shown in Fig. 8. To prevent gas evolution, the stud may be electro-plated with iridium. It may be mounted on an iron base-plate U, Fig. 6, on which is an iron pin R let into the stud and serving also to centralize the magnetic field. The annular electrode B may be carried by a radial arm attached to a socket which fits over a refractory support; or by three arms; or by a conical spiral serving to produce the magnetic field. It may have various shapes in cross-section. The arc may be struck electro-magnetically or by an ionizing heater which is cut out of circuit when current flows between the electrodes. In one construction of lamp, a silica or glass bulb 16, Fig. 24, which may contain an inert gas or a few drops of mercury or compounds of aluminium, titanium, calcium, thallium, caesium, lanthanum, or lithium, is fitted with a conical stopper 17. Supports 10, 11 for the electrodes are made of platinum, platinized iron, or invar, and are secured in tubes 13 on the stopper. The stud of the central electrode is mounted on a plate 6 pivoted to the support 10, so that when current is off the stud swings against the ring electrode 2. The support 10 and plate 6 form a magnetic circuit for a series solenoid 15. In a modified striking-arrangement, a conical spring-urged solenoid-core is drawn into a conical socket when current is flowing, but rests on a lateral stud when current is cut off, so as to swing sideways and bring the stud electrode against the ring. A series coil 19, Fig. 24, is located in a groove in an external casing provided with heatradiating ribs and secured to a cap 20. The space between the cap and the stopper 17 is filled with cement. A concave reflector 7 is placed above the electrodes.

Title: Electronic arithmetic unit sub-assembly
IPC: G06F7/494
Filed: 1970-02-12
Abstract: 1,256,321. Adders. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Feb., 1970 [15 Feb., 1967], No. 6835/70. Heading G4A. In an arithmetic unit comprising a one-bit input register LR, a three input one-bit adder AV, and a one-bit output register RR responsive to timing pulses CP, the output of the input register is connected to one input A of the adder through a blocking, BL, and complementing, KL, circuit, a second blocking circuit BF is connected to the same input A of the adder, to form, with the first, a code correcting circuit, and the output of the output register is connecting to a second input B of the adder through a second complementing circuit KR. In operation the first addendum is loaded in the input register and, with all the external inputs at zero including input Z which together with a first clock pulse CP sets the output register RR and hence input B to zero, passed through to the output register into which it, is loaded when the second clock pulse CP occurs. The second input B to the adder thus becomes equal to the first addendum, and the second addendum is then loaded in the input register LR and passes to the input A of the adder AV, the carry C being brought from the preceding stage. The circuits KL and KR responsive to external inputs provided, e.g. by a computer programme, enable either or both addenda to be processed in complementary form, e.g. for subtraction. The result appears on the output D from the adder AV and is loaded into the output register on the occurrence of the third clock pulse CP. In the case where, e.g. the excess-3 code is being used the second addendum from the input register LR may be blocked by the circuit BL and the appropriate correction values supplied via the stage BF from the input F. Modifications.-When the next operation is to follow immediately the output register RR must be erased to provide the zero input at B. If the resulting delay is not acceptable a further blocking stage is added between stage KR and input B thereby allowing the result to remain in register RR longer. This extra stage is activated externally and the input Z is omitted. Alternating carry, i.e. the carry signal changes polarity from stage to stage, may be used to reduce the number of amplifiers required. In this case an additional complementing stage is inserted between adder input B and the further blocking stage which is added between stage KR and input B (see above) to invert the signal at input B of the adder. The carry signal C may also be passed through a blocking stage to the carry input of the adder and through an inverter to the carry output of the adder, both the inverter and the blocking stage being activated by the external input to the additional complementing stage which is omitted. Constructional features.-The input and output registers are bi-stable circuits, though they may be core stores, and the adder is a conventional two stage exclusive-OR device.

Title: Machine for manufacturing toothed wheels, worm wheels or the like
IPC: B23F5/12
Filed: 1921-03-03
Abstract: 159,884. Wingquist, S. G. March 10, 1920, [Convention date]. Gear-cutting.-In gear generating machines of the type in which the generating movement between the tool and the blank is produced by an approximating link mechanism, the required rolling angle is attained by displacing the link system on both sides of its normal position so that the deviation from the theoretical motion is reduced to a minimum. Fig. 1 shows a link system comprising a link a fixed to the axis x of of the wheel C and a link b rotatable about an axis x<1> fixed relatively to x and slidably and rotatably mounted at the fixed point 0 and at a<1>. On displacing the wheel C from 0 to o, a point on the wheel describes a curve K differing from the theoretical cycloid curve Z. According to the invention, the link system is displaced as shown in Fig. 2 so that a point on the wheel describes a path a<2> 0 a<1>, very closely approximating to the theoretical curve. As shown in Fig. 4, the wheel axis remains stationary while the tool W and the point 0 are moved between the positions indicated to generate the tooth face E<2>. In a modification, the mechanism is so arranged that the tool W will intersect the pitch circle of the gear when the link system is in the normal position so that the error at the pitch circle is in this case zero. The invention is stated to be applicable to the cutting of straight or helical spur or bevel gearing and to all forms of approximating link mechanisms.

Title: Improvements in or relating to nuclear fuel elements
Inventor: KEALY WELLESLEY ASHE
IPC: G21C17/10
Filed: 1961-03-06
Abstract: 967,473. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 26, 1962 [March 6, 1961], No. 7405/62. Heading G6C. [Also in Division H4] The temperature of a nuclear fuel element is determined from the resonant frequency of an acoustic resonator in thermal contact with the element. The fuel element, which is similar to that disclosed in Specification 779,408 comprises a nuclear fuel member 11 enclosed in a magnesium alloy sheath 12 having longitudinal heat transfer fins 12a and, at each end of member 11, heat insulating discs 13, 14 to reduce heat transfer between elements when a number of elements is stacked in a column by means of the male and female end fittings 15, 16 respectively. The resonator which is mounted by means of locating fins 21, is of the double Helmholtz type and comprises an elongated tubular casing 17 in which an orificed web 18 defines two communicating cavities 19, 20. An acoustic transmitter 22 and an acoustic receiver 23, each comprising an electromagnetically driven diaphragm, are employed, utilizing the resonance frequency method, to determine the temperature of gas in the resonator and thus the temperature of the fuel element. The resonator may be sealed or unsealed and in the case of a gas cooled reactor the gas filling may be the gaseous coolant. The resonators associated with difference fuel elements in a stack have different spaced resonant frequency bands so that a particular fuel element may be identified. In other arrangements the resonator may comprise a whistle excited by the flow of reactor coolant, or a resonator excited by noise in the reactor or by an injected acoustic signal of varying frequency may be employed. The resonant frequency of the resonator may be altered by means of a temperature responsive element such as a bi-metallic strip.
