Title: Method and means for facing and truing the electrodes of spot welding machines
IPC: B23K11/30
Filed: 1956-02-16
Abstract: 853,470. Grinding spot-welding electrodes. TAYLOR, J. E. Feb. 18, 1957 [Feb. 16, 1956], No. 4813/56. Class 83 (2). [Also in Group XXIII] The electrodes of spot-welding machines are faced and trued by sandwiching a rotatable grinding element between the electrodes when they are urged together and rotating the grinding element by reciprocating carrier means for the element transversely of the electrodes. A frame comprises side members 12, 13 of channel-section and end members 15, 17, the former providing a handle 16. Within the frame is a flanged bobbin 18, circular apertures therein exposing a grinding disc 22 fixedly mounted within the hub 23 of the bobbin. The disc 22 is held against rotational movement with respect to the bobbin 18 by a key and against movement axially of the bobbin by spring-rings 25 in grooves in the hub 23. A flexible cable 26 is looped around the hub 23; a nipple secured to one end of the cable engages a keyhole slot 29 in the end member 17 and a nipple 28 secured to the other end of the cable engages a screw-threaded socket 27 in the end member 15 whereby stretch in the cable can be taken up. In use, the frame is held so that one side of the grinding disc 22 rests against the fixed electrode 30; the movable electrode 31 is then brought substantially into welding position so that it bears against the other side of the disc 22 and the frame is then reciprocated causing the bobbin and grinding disc to rotate first in one direction and then in the other. A set of interchangeable grinding-discs 22 of varying surface forms may be provided for selective fitment to the bobbin 18.

Abstract: 672,375. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 27, 1950 [March 3, 1949], No. 4981/50. Class 29 The motor driving the compressor of a refrigerating system, including a T-shaped evaporator 8 having a shelf-part 12 to which the liquid refrigerant is first fed, is controlled by a thermostat bulb 24 mounted on a bracket 29 of low thermal conductivity on the shelf 12 and held in place by a fin 27 extending into the storage space so that the bulb is responsive both to the temperature of the shelf and of the storage space. The bracket 29has a pip 31 about which the fin 27 pivots when a screw 28 is tightened so that the bulb is clamped. Alternatively the bracket and the fin have inclined parallel parts which give a relative movement when the screw is tightened to secure the bulb. The fin may be of aluminium and the bracket of stainless steel.

Title: Digital transmission system
IPC: H04L7/033
Filed: 1967-02-03
Abstract: 1,115,894. Data transmission systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 3 Feb., 1967 [9 Feb., 1966] No. 5318/67. Heading H4P. To aid synchronization in the receiver of a digital transmission system data words in which there is less than a given number of transitions have alternate bits inverted prior to transmission. Each word in the embodiment described is preceded by a tag bit, always zero for input words. The data is in NRZ form. The number of transitions in a word is counted, any transitions corresponding to the tag bit being ignored. If the count exceeds a given number the word and tag are transmitted unchanged, but if it does not exceed that number the tag and the evennumbered bits in the word are inverted. At the receiver the transitions in the received signals are used to synchronize the receiver clock; no detail is given. The tag bit is inspected to determine, its state and if it is a zero the associated word passes to the output unchanged. If it is a 1, however, the tag bit and the even-numbered bits are inverted, so reconstructing the original data. The circuitry, Fig. 1 (not shown), comprises logic units for performing the various operations at the transmitter and receiver.

Abstract: 647,470. Magnetrons. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 27, 1947, No. 5709. Convention date, Nov. 13, 1942. [Class 39 (i)] A multi-resonator magnetron has a tuning member 3 having an elongated axial support 4, 9 which is so constructed that its expansion or contraction when the temperature of the magnetron varies moves the tuning member 3 to compensate at least partly, and preferably completely, for the change in operating frequency due to expansion or contraction of the anode structure 2, 7. The tuning member 3 is disposed at one end of the anode and when it moves it varies the coupling between the resonators at their open ends. The support 4, 9 for the tuning member 3 extends through a central aperture in magnetic polepiece 6, and member 4 can slide over the surface of insulator 8 which centres the cathode 16. Members 4, 9 are secured together by nuts 10, 11, and rod 9 passes through a flexible diaphragm 14 soldered to the casing of the device. A screw 15 carrying a nut 12 is sealed to the diaphragm 14 and secured to the rod 9, and the nut 12 engages a bearing 13. The operating frequency may be varied independently of the thermal compensation by turning nut 12. The remaining constructional details are as described in Specification 635,479.

Abstract: 845,542. Indicators for selective signalling systems. SIEMENS EDISON SWAN Ltd. Feb. 20, 1957 [Feb. 24, 1956], No. 5834/56. Addition to 721,683. Class 40 (1). In an electrically-operated changing display indicator of the kind described in the parent Specification, the chains 2 carrying the display panels 1 are driven by an electric motor which is permanently coupled to the driving mechanism and is energized when a coded signal is received to drive the indicator to the required position, the motor driving the indicator through a high ratio reduction gearing, friction being sufficient to bring the indicator to rest at the required position when the motor is de-energized. The motor is energized through a circuit having four lines which are energized in a combination to set the position required. The indicator has a number of contact discs 52 formed with cutaways and co-operating with wipers 58 to form a number of branches of a code circuit. When a signal is sent the motor is energized through the code circuit and drives the indicator until no circuit exists through any of the branches and is accordingly de-energized. Friction, as stated above, then brings the motor and indicator to rest in this position. The motor consists of two electromagnets arranged at right-angles and mounted on soft iron brackets 22. The rotor 27 is unwound and consists of a pair of polepieces which are attracted in turn towards the nearest magnet. A soft iron yoke 41 completes the magnetic circuit. The magnets are energized alternately through contacts on bladesprings 42, 43 and 44, 45 which are controlled by cams 39a, 39b mounted on the motor spindle 21. Another embodiment is described in which the indicator consists only of a rotating structure carrying three indicator panels, the structure being driven through a motor controlled by code discs as before.
