Title: Improvements in or relating to electrically driven vibratory devices such as tuning forks
IPC: H03B11/06
Filed: 1928-05-24
Abstract: 317,878. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). May 24, 1928. Commutator switching arrangements.-An electrical drive for a vibratory element such as a tuning fork consists in charging a condenser through contacts actuated by the fork, the discharge from the condenser energizing the driving magnet and occurring whilst the fork is passing through its position of rest. The contacts are broken whilst they are substantially currentless. As shown, the fork prong 2 carries a blade contact 3 co-operating with fixed contacts 4, 5 in the circuit of the driving electromagnet 6. A condenser 11 in the primary circuit of a transformer 14 is charged when contacts 3, 4 are engaged and is discharged through the electromagnet 6 after contacts 3, 5 have engaged. In order to prevent chattering of the movable contact, it is given a preferred form, Fig. 3, comprising a woven bronze ribbon 3 into which the contact 22 is welded. In other forms, the movable contact 3, Fig. 3, is separated from the prong 2 and is actuated by a small permanent magnet 18 mounted thereon, the damping being obtained by a jockey roller 17 or by a further permanent magnet.

Title: Improvements in apparatus for the detection of smoke from furnaces
IPC: F23N5/00
Filed: 1930-05-19
Abstract: <PICT:0354419/III/1> One or more spark gaps p are arranged in a flue d in the path of the flue gases and connected to the secondary winding of a transformer or spark coil T, current variations in the primary winding of which, upon passage of sparks, are used to give visible or audible warning of the presence of smoke.  The primary winding is in series with a limiting resistance r and the magnet coils m<1>, m<2> of a relay Y.  Normally the armature a of the relay is held by a spring g against a stop s but when a spark passes due to the presence of smoke the increase in the primary current attracts the armature closing a circuit supplying lamps l<1>, l<2>, and an electric hooter or bell k.  The lamps may be embodied in a sign as shown.  The lamps and hooter may be connected directly in series with the primary winding of the transformer.  The relay may be connected across the limiting resistance r, or across the primary winding.  Two or more sparking plugs in different flues may be connected in parallel.  The potential across the spark gap may be adjusted by a switch which puts more or less turns in the primary circuit, and such switch can be calibrated according to various densities of smoke and marked "Haze," "Medium," and "Heavy."  Tappings may be taken from the secondary winding to vary the potential across the spark gap. According to the Provisional Specification the warning device may comprise luminous discharge tubes, an ammeter or a voltmeter, and the relay may include a coherer.

Title: Apparatus for selective processing of information characters in a data processing system
IPC: G06F9/302
Filed: 1966-04-06
Abstract: 1,139,675. Data processing systems. GENERAL ELECTRIC CO. 6 April, 1966 [6 April, 1965; 14 April, 1965; 15 April, 1965], No. 15380/66. Heading G4A. In a data processing system, four adjacent memory locations of a memory 10 are specified as a temporary store, and an instruction " Explode " causes a 24-digit word contained in the memory location specified by the instruction to be transferred in 6-digit sections (0-3) to the least significant digit section A of the four temporary store locations, the most significant data section (3) occupying the section A of the least significant word of the temporary store, and, depending on the value of a register 314 which determines the number of sections of the data word to be transferred, remaining data sections occupy sections A of successively lower order temporary store words. A reverse instruction " Implode " causes the least significant sections of the temporary store words to be transferred sequentially into a memory location, specified by the instruction, to form a single data word, the number of sections to be transferred being again determined by register 314, and any unaffected sections of the specified memory location being cleared to zero. A further instruction " Shift " is also available and operates on any number of the four temporary store word locations to left or right " shift " the contents in an open or circular manner. In performing this instruction, the temporary store words are transferred sequentially to M-register and the required shift carried out using E-register and adder 302. In a circular shift, digits shifted out of the first store word to be operated on are retained in a further temporary store location and added on to the digit positions of the last store word which are vacated through shifting that last store word. In an open shift, digits shifted out of a word are lost. The number of digit positions shifted, the direction and kind of shift, and the number of temporary store words affected, is determined by relevant parts of the shift instruction word, all instruction words being introduced sequentially from memory into I and D-registers by a counter 310. The position of the temporary store, which position is movable, is initially set by an instruction word which introduces into A-register the address of the most significant word of the temporary store and each word read out of memory has a 25th digit which is submitted to a Parity Check unit 316, the latter also supplying the correct 25th digit when words are read into the memory.

Abstract: 1467612 Integrated Darlington circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 April 1975 [18 April 1974] 15403/75 Heading H1K [Also in Division H3] In an integrated circuit comprising six paralleled Darlington pairs of transistors each driver transistor is more closely thermally coupled to the output transistor of one of the other pairs than it is to its own output transistor. A N-type chip forming the common collector of all the transistors has P-type base regions 3, and 4 for the output transistors and drivers respectively separated by collector material 5. The N-type regions E 1 <SP>1</SP>-E 6 <SP>1</SP> forming the driver emitters are connected by metalization to the comb shaped base electrodes B 1 <SP>1</SP>- B 6 <SP>1</SP> of the output transistors. The P-type base material has a sufficiently high resistance to separate effectively the base regions. Interdigitated with the base electrodes are the common N-type emitter region E of the output transistors. By cyclically offsetting the output transistors around drivers, the chief thermal effect on each driver is from an output transistor other than its own.

Abstract: 181,703. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen, and Kore f, F.). June 18, 1921, [Convention date]. Void (Published under Sect. 91 of the Act]. Modifying physical characters of metals.- Tungsten and other refractory filaments are formed of crystals overlapping in the direction of the filament, and occupying a considerable part or the whole of the cross section of the filament, in such a manner as to be flexible at ordinary and at high temperatures. A drawn filament is heated to a temperature at which the fibrous structure begins to break up, and is then more strongly heated so that the products of the breaking up unite to form new crystals. The filament may be treated mechanically between the two stages of heat treatment. In an example, drawn tungsten filament prepared as described in Specification 23499/09 [Class 82 (i), Metals, Extracting &c.], is heated by drawing it continuously between electric contacts in an atmosphere of mixed hydrogen and nitrogen, and is then drawn through a die to reduce its diameter, and is finally heated more strongly in similar manner. Small quantities of refractory and difficultly reducible oxides may be added to the raw material of the drawn filament. Specification 16620/14 also is referred to.

Abstract: 479,518. Free - piston compressors. PESCARA, R. P. June 3, 1936, No. 15576. Convention date, June 3, 1935. [Class 8 (i)] Combustion in a space 1 actuates pistons by which air is compressed in spaces 3<1>, this air being supplied for scavenging and combustion to the space 1 from the storage cylinder 5 ; the scavenging air and gases of combustion are supplied to a turbine &c. The pistons are returned by the energy stored in the clearance spaces and an additional source such as pressure in cushions 101 or vacuum in spaces 11<1>. The pressure in the combustion space is maintained between limits set by the strength of the materials and the pressure necessary for combustion by choice of dimensions especially of piston diameters, by the positions of the engine inlet and outlet ports, and by determination of the additional energies. These energies may be influenced by varying the maximum or minimum pressures or varying the clearance volumes of the cushioning spaces, or the compressor inlet pressure may be varied. Fig. 5 shows apparatus wherein the maximum and minimum pressures of the cushions 10 are varied by pressure on the valves 16, 17 conveyed through links and levers from a hydraulic cylinder, the slide valve 22 of which is controlled by the engine pressure. Alternatively, this cylinder may control the clearance in vacuum space 11, by a piston 20. The return energy may be increased at starting by provision of a stop 37 for the rod 19 acting in the valves which stop is released by heat-actuated bellows 36 when normal working is attained. Specification 424,971 is referred to.

Filed: 1974-04-09
Abstract: 1444479 Shielded containers UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 9 April 1974 [17 April 1973] 15582/74 Heading B4Q [Also in Divisions G4-G6] A storage cask for high-level radioactive wastes housed in a container 10 comprises a thick-walled metal capsule 11 with a plug 13 sealed in place with a deep penetration weld 12, the thickness of the walls of the capsule being sufficient to reduce radiation to a tolerable level and to permit storage of the cask out-of-doors. Natural convection of air over the cask removes the decay heat. Low carbon steel is a suitable material for the cask, preferably with 0À25 wt. per cent Cu having been added to improve corrosion resistance by promoting the formation of a tightly held oxide coating. In place of carbon steel, other metals such as Pb or U could be utilized. To promote the natural convection around the cask, this is supported on precast saddles 14. Such casks are preferably stored in a dry, arid climate for 150 years or longer, after which they can be placed in a hard rock mine where the thermal conductivity of the rock will be sufficient for excessive temperature increases in the wastes not to occur. If the wastes are solely from Pm-recycle pressurized-water reactors, the high neutron dose rate around the cask must be reduced either by surrounding the cask in its storage position with crushed graphite (Fig. 2, not shown) or by placing cooling fins on the cask and employing neutron shielding material such as polyethylene between the fins (Fig. 3, not shown).

Abstract: 552,696. Testing tensile strength of materials. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 5, 1941, No. 15699. Convention date Dec. 5, 1940. [Class 106 (ii)] A substantially rigid force-measuring element is connected in series with the specimen and:a' force indicator by means of a flexible string-like element which bows at high-frequency vibration of the force-measuring element and thus avoids transmission of the vibrations to the indicator. The motor M drives through universal couplings 7, 8, 9 and speed-reduction gears 10, 11 a vertical spindle 6 provided with a screwed portion 5 which engages a nut 4 on a yoke 3 engaging by the part 2 a collar on the specimen S. The latter is surrounded by al sleeve H which may be heated by an electric coil. The upper end of the specimen is attached to a spring bar 1 of flattened "O" shape of non-uniform crosssection to distribute the pull uniformly. A pin 13 attached on the inside of the lower limb of the "O" passes through the upper limb and is attached by a piano wire 14 to a recording lever 15 pivoting at 16 about cross plate spring pivots. A similar wire 20 is attached to an upper bar secured to the specimen and passed around pulleys 18, 19 on a lower bar 17 also secured to the specimen and up over a pulley 21 to a tension weight 25 after wrapping around the spindle ,of the recording cylinder. Since there are two vertical lengths of wire, the drum .is rotated an amount corresponding to twice the strain, ,whereas the pointer is moved ,according to the stress. When the specimen breaks, the wire 14 vibrates as shown and does not transmit shocks to the pointer. For slow speeds of testing, the motor .drives the spindle 6 through the reduction gears, but for high speeds drives direct. The nut disengages the screw if the motion of the nut 4 is.too,rapid to avoid breaking the spindle 6. A timing mechanism may be included in the motor energising circuit to interrupt the motor after a predetermined interval.

Abstract: 1512485 Servomotor systems in pipe fracture safety device P D RASSPE 21 April 1976 [19 Sept 1975] 16068/76 Heading G3P In a pipe fracture safety device, the connection of actuator means (4), for operating a shut-off valve (3) in a main pipe-line, to the main pipe-line upstream of the valve (3) is controlled by a differential pressure valve 10, the drive mechanism of which comprises a piston 40 movable within a housing defining two chambers 41, 45 and having two inlets which are connected via branch lines 29, 30 with the main pipe-line downstream of the valve (3), a throttle (31) and time-delay reservoir (32) being provided in the branch line 30; during normal operation of the main pipe-line system the piston 40 is held against an annular surface 42 between the two chambers 41, 45 which are of different diameters, the pressure difference across the piston as the result of different areas of the piston being exposed to the chambers 41, 45 being sufficient to counterbalance the force exerted by a spring 47 which urges the piston towards the chamber 45 which communicates with the inlet 30. On occurrence of a fracture in the main pipe-line, the pressure in chamber 41 will fall immediately, and after a time delay the pressure in chamber 45 will fall until the pressure difference across the piston is no longer sufficient to prevent the piston from moving towards the right (as viewed in Fig. 2) under the action of the spring 47. Such movement of the piston switches the valve 10 to permit actuation of the means (4) to close the valve (3).
