IPC: B23K11/26
Filed: 1969-09-10
Abstract: 1,266,010. Spot welding systems. INSTITUT ELEKTROSVARKI IMENI E. O. PATONA. 10 Sept., 1969, No. 44712/69. Heading H2H. A spot welding machine wherein a capacitor is charged and then discharged into a welding transformer to effect a weld is controlled so that the capacitor is discharged twice in succession, the first discharge being effective to form the contact surfaces of the weld and the second discharge effecting the weld. A spot welding apparatus comprises a welding transformer 7 which is energized by the discharge of a capacitor 3 under the control of a thyristor 6. To start a weld a push button is operated which closes contacts 27 and opens contacts 27<SP>1</SP>. Opening of contacts 27<SP>1</SP> biases bi-directional device 1 into conduction thereby to charge the capacitor 3. The increasing voltage across the capacitor 3 appears across potentiometers 9, 10 to charge capacitors 11, 12. The voltage across capacitor 11 eventually causes a breakdown device 22 to conduct so as to produce a pulse in a transformer 15 which triggers the thyristor 6 to discharge the capacitor 3 through the welding transformer 7 in a pulse having an amplitude determined by the setting of potentiometer 9 and the value of the capacitor 11. Capacitor 11 does not recharge since device 22 is maintained conductive by a bias source 26 so that at the end of the pulse the capacitor 3 re-charges until the capacitor 12 charges from the potentiometer 10 to break down device 23 whereupon a pulse appears at transformer 16 again triggering thyristor 6 to discharge the capacitor 3 through the welding transformer 7, the pulse amplitude of the second pulse being determined by the setting of potentiometer 10 and which is higher than that of the first pulse. Simultaneously the pulse in the transformer 16 breaks down a device 29 to render the bidirectional device 1 non-conducting to end charging of the capacitor 3. The first pulse through the welding transformer 7 prepares the surfaces to be welded and the second pulse effects the welding operation.

Abstract: 1295691 Accelerometers WESTINGHOUSE BREMSEN-UND APPARATEBAU GmbH 5 Feb 1970 [20 Feb 1969] 5530/70 Heading G1K [Also in Division G3] Apparatus for detecting angular acceleration comprises a rotatably driven mass 5 driving another mass 7 through a resilient coupling including a deflectable vane 18 located between first and second conduits 21, 22 so that it can deflect a stream of fluid leaving conduit 21 away from conduit 22, so that the amount of fluid entering the conduit 22 is dependent on the angular acceleration of the mass 5. As shown in Fig. 1, the mass 5 is in the form of a disc driven by a V-belt 4 and drives the inertia mass 7 by means of a pin 14 carried eccentrically by an adjusting screw 16 in the disc 5, the pin 14 engaging a radial slot 13 in a lever 8 pivoted on a pin 9 in the mass 7 and the lever 8 being forked to embrace a leaf-spring 12 secured to the mass 7. The lever 8 carries a blade or vane 18 extending into the gap 25 between a discharge nozzle 19 and a collecting nozzle 20 connected respectively to a source of compressed air by a bore 24 and union 23 and to an instrument (which may be an indicating instrument) by a larger bore 22 and union 24. The vane 18 prevents air from entering the nozzle 20 until the disc 5 undergoes acceleration, causing the mass 7 to lag and the vane 18 to be deflected so to uncover the nozzle 20 that the pressure of the stream of air received thereby will depend upon the acceleration and provide a measure thereof. In a modification, Figs. 3 and 4 (not shown) a rotating shaft drives the inertia mass through a resilient coupling comprising a coil spring in a fork secured to the mass embraced by the forked end of a lever carrying a vane deflectable in the gap between two axially aligned nozzles, the discharge nozzle being rotatable with the inertia mass and communicating with a channel therein supplied through a bore in its journal parallel to an axial bore therein connecting the collecting nozzle to the instrument. An alternative resilient coupling for either embodiment is obtained by making the lever resiliently deformable.

Abstract: 1295789 Indamine dyestuffs L'OREAL 19 April 1971 [10 April 1970] 26659/71. Heading C4P  Indamine dyes and their inorganic or organic addition salts have the general formula wherein each of R 1 , R 2 , R 3  and B 4  independently represent H, halogen, C 1 -C 6  alkyl or alkoxy and R 5  and R 6  either both represent hydrogen or both represent the same or different optionally substituted alkyl radicals. Suitable salts include the tartrates, acetates, arylsulphonates, hydrochlorides, persulphates, perchlorates and the zinc chloride double salts. The compounds may be prepared by condensing 2,6-diaminopyridine with a para-phenylene diamine of formula in an aqueous, aqueous alcoholic or aqueous acetone medium in the presence of an oxidizing agent and optionally converting the resulting indamine or indamine salt into a desired salt. The oxidizing agent is suitably H 2 O 2  or an inorganic per-salt. Compounds where at least 2 of R 1 , R 2 , R 3  and R 4  are not hydrogen may be obtained by condensing 2,6-diaminopyridine with a quinone diimine of formula in an aqueous medium or in an inert solvent, in the presence of an acid corresponding to the desired salt. Compounds where R 5  and R 6  are both alkyl groups may also be prepared by condensing 2,6-diaminopyridine with a pnitroso-N,N-dialkylanidine of formula in an aqueous or alcoholic medium at 30-60 C. The compounds of Formula I are used for dyeing keratinaceous fibres, e.g. hair, either alone or in compositions containing other dyes and other ingredients conventionally employed in hair dyes. They can also be employed in the form of wave-setting lotions.

Abstract: 1296560 Artificial satellite TOKYO SHIBAURA ELECTRIC CO Ltd 24 July 1970 [25 July 1969] 35952/70 Heading H4D An artificial satellite 1, Figs. 4, 6 of the type which spins about an axis 4, possibly subtending an angle E with the local horizontal 5, is provided with a pair of infra-red sensors 6, 7 in the plane of the axis 4 and detecting along respective single lines angularly spaced by # either side of a perpendicular 8 to the axis. The spinning of the satellite causes the sensors 6 and 7 to produce outputs 106, 107, Figs. 11a, 11b respective as their detection lines scan the Earth's disc through angles 2#, Fig. 6. The "attitude" angle E is related to angle # by the equation: where This equation is shown in Fig. 7 for sensor 6, line 11, and sensor 7, line 12. The line 13 indicates the variation of the difference between # for the two sensors with E. Fig. 8 illustrates the variation of dE/d# with E for line 11 (111) and line 13 (113). It is seen from line 111, extended to the dotted portion, that for small values of E<50 degrees, a slight error d# in # produces an unacceptably large error dE in E. Using the difference line 13 however for E<50, it is seen that a slight error d# produces only a small error dE. In the circuit of Fig. 9, the commencement of output 106 starts trigger 14 and clock pulse counter 15 whilst the commencement of output 107 stops said counter. The count thus represents time T1 and the difference between the two angles # as per line 13. For values of E where only one sensor 6 intercepts the Earth's line 11 is used.

Abstract: 1296600 Testing radio transmitter-receivers BURNDEPT ELECTRONICS (ER) Ltd 15 July 1971 [16 July 1970] 34551/70 Heading H4L A battery powered radio transmitter/receiver equipment particularly for use as an emergency radio beacon, incorporates equipment for testing R.F. power output, modulation and battery voltage, which gives a signal only if all three quantities reach a predetermined level. As described the transmitter is is carried on the person and is switched on automatically on ejection from an aircraft. To test the equipment, a lever on the equipment housing is lifted to operate two reed switches which connect the test circuit to the battery and the aerial output to a dummy load R1, Fig. 2. The modulated R.F. signal across Rl when the device is operating as a beacon is detected (D1, R2, C1) whereby the A.F. modulation is coupled via capacitor C2 to a transistor T1 and integrated (C3, R3). When C3 charges to a predetermined potential, T2 conducts and provides bias to turn on T3 if T5 is conducting. A predetermined portion of the "no load" battery voltage is compared with a reference voltage derived from a Zener diode D2, and if this is correct T4 is turned on, charging C4 via R4 so that T5 conducts and is held on by the charge on C4 during periods when the battery is on load. With T3 and T5 on, a green lamp L G  is operated via T6 and T7 is cut off to switch off a red lamp L R . T8 in conjunction with D2 provides a stabilized supply to the lamps. The operation of the battery economizer, which interrupts the carrier, is indicated by the lamp L G  switching on and off. When the device is switched to transmit speech the carrier power is cut by 25% with no modulation and it is necessary to whistle into the transducer to cause the green light to operate which also checks the transducer as a microphone. To check the receiver a modulated test oscillator is brought into operation and loosely coupled to the receiver input. The resulting tone output from the receiver checks the transducer operating as a loud-speaker and it is also amplified by transistor T9 which is coupled to transistor T1 so that the green light operates if if the level is adequate. Lamps L G , L R  are preferably solid state types.

Filed: 1970-07-14
Abstract: 1314389 Valves KOEHRING CO 14 July 1970 34136/70 Heading F2V A control valve having a fluid-actuated spool 5 which can be moved in one direction (to the right) by fluid pressure exerted on one portion 19 thereof with fluid escaping from a pressure chamber 22 associated with another portion 20 of the spool, is characterized by vents 40 which can be rendered ineffective as a consequence of movement of the spool 5 so as to prevent further movement of the spool, and a stop 41 associated with the chamber to vary the extent that the spool moves before rendering the vents 40 ineffective. As shown, the control valve is in the neutral position the pressure in line 14 being exerted equally on the ends the spool 5 through bores 25 and 23. Movement of the pilot valve 9 to the right connects the pump to a chamber 26 and the resulting pressure difference on the spool 5 moves it to the left. The motor 7 is then connected to the supply line 15. Movement of the pilot valve 9 to the left (Fig. 2, not shown) places chamber 26 in communication with the reservoir and the resulting pressure difference on the spool 5 moves it to the right. When the spool 5 has moved to close off the vents 40, fluid is trapped in the chamber 22 bringing the spool to a halt. The speed of lowering of the motor determined by the extent of opening of grooves 43 is therefore adjustable by the screw 41. The motor may be double acting (Fig. 3, not shown). Both the rate of hoisting and the rate of lowering may be similarly controlled (Fig. 4, not shown). The vents 40 may be axially spaced each controlled by a shut-off valve (Figs. 5 and 6, not shown).

Abstract: 1317112 Microphones S G BROWN Ltd and T D IBBOTSON 17 Feb 1972 [7 June 1971] 19268/71 Heading H4J A microphone, e.g. for use under conditions where ice formation may occur, comprises a microphone transducer 10 supported in a resilient casing 24 having at least one portion stretched between rigid supports (which may be formed by a single rigid housing 12) so as to be spaced away from the transducer 10 and leave an air space or spaces 25, 26 in the casing 24 between the resilient casing material and the transducer 10. With this construction, if ice forms on the surface of the casing 24, this can be broken away by pressing the resilient casing 24 inwardly towards the transducer 10. The ice can thus be readily removed and the resilient material can act as a sound transmitting diaphragm. Silicone rubber is preferably used for the casing 24 since ice will not adhere to it. The transducer 10 is a balanced armature differential type and is inserted in a recess 11 in housing 12. At one end the housing 12 has an axial bore 13 for microphone leads 14 and, around this bore 13, the housing 12 is of cylindrical form 15 terminating in a frustum of a cone 16. An annular groove 27 is provided. The housing 12 extends across the front and back of the transducer 10 and has sound ports 19, 20 into which fit metal washers 22 secured to the housing 12 and transducer 10. The casing 24 is of cylindrical form and fits over the housing 12, closing the recess 11 through which the transducer 10 is inserted and having a flange which fits into the groove 27. The assembly may be attached to a headset boom (not shown), of tubular form, through which the leads 14 pass. The boom is sealed into recess 13. A dowel pin 28 in an offset hole running through housing 12 locks into a groove cut in the wall of the boom tube, thereby securing the assembly on the boom.

As shown the bars are black on a white background and a number begins and ends with black bars commencing with a "0" A and finishing with a "1" B to indicate the direction of scan. A parity bit P may be included to ensure an odd number of bars. The bars alternate with no two white and no two black bars being adjacent. A hand-held reader has three circular reading areas arranged with their centres on the corners of an equilateral triangle (Figs. 4, 5, not shown). Each area is fed with light from a source 185 inside or outside the reader via light conducting fibres 165, 166, 167 and reflected light is fed via further fibres to respective photosensors 190, 191, 192 which feed a decoding circuit. The bars and reading areas are so arranged that the reading areas are never all contained within a narrow bar and never completely scan two narrow bars or one wide bar. The decoding circuit (Fig. 7, not shown) contains AND gates and two sets of flip-flops for each photo-sensor and is arranged to detect when all photo-sensors have passed a junction between bars of two colours whether all sensors read the same colour or whether they read different colours and to feed the result i.e. a "0" for different colours and a "1" for the same colour to a shift register. The data in the shift register may be read out in reverse if the A and B bits indicate the data is read in reverse or may be entered into the shift register in reverse.
