IPC: H01R4/66
Filed: 1958-11-07
Abstract: 880,436. Earth electrodes. LEDOUX, C. P. Nov. 7, 1958 [Nov. 9, 1957], No. 35850/58. Class 36. An earth electrode system comprises an earth electrode buried in soil containing sufficient calcium sulphate to reduce substantially the resistance of the soil in the resistance area of the earth electrode system. Preferably, the amount of calcium sulphate is such that, with an average rainfall of 60 cm. infiltrating water will take at least ten years to remove suihcient of the calcium salt to impair the reduction in resistivity, and the Specification states that 4 to 8 kg. per square metre would suffice for this purpose. Other substances may be used in conjunction with the calcium sulphate for either increasing or decreasing its solubility or for modifying the acidity or structure of the soil, the effect of several of these being indicated in the Specification. The calcium sulphate may be incorporated by spreading, trenching, hoeing or ploughing with or without the additional substances. Specification 657,989 is referred to.

Title: Explosive actuated driving device
IPC: F16B19/14
Filed: 1960-10-24
Abstract: 927,476. Cartridge-operated fastener driving tools. OLIN MATHIESON CHEMICAL CORPORATION. Oct. 24, 1960 [Nov. 9, 1959], No. 36433/60. Classes 9 (1) and 119. A cartridge-operated fastener driving tool of the piston or plunger type comprises a piston having a rear portion 4 formed of relatively soft metal and a front reduced portion 3 of relatively hard metal with means for detachably securing the fastener 1 and a piston arrester 33, 34 adapted to form a restriction adjacent the tool muzzle to initially retard and finally stop the piston in its movement beyond the restriction by deformation of the rear portion 4, the front portion 3 being of sufficiently reduced size to pass the restriction. The arrangement is such that the fastener 1 is sufficiently forwardly spaced from the deformable portion 4 to reach, on firing, its predetermined position or not excessively beyond it before the restriction begins to arrest the piston. The piston arrester may comprise swinging jaws but, as shown, it is formed of a plurality of resilient jaws 33, 34 normally sprung outwardly and mounted on a ring-like base screw threadedly mounted at 36 on the tool barrel 30. In the inoperative position the die-like restriction 33<SP>1</SP>, 34<SP>1</SP> is sufficiently open to ermit insertion or removal of the piston but in the operative position with the tool pressed against the workpiece 75, a cam ring 40 carried by the tool shield cams the jaws 33, 34 inwardly to form a die restriction large enough to pass only the fastener 1 and front portion 3 of the piston. The front and rear portions of the piston may be either integral or two parts secured together. In the latter case the front part may be of hard steel while the rear part may be of soft iron or steel, copper, aluminium or suitable alloys thereof. The piston may be coated or plated, e.g. with copper to avoid corrosion and/or for lubrication. The front and rear portions 3, 4 of the piston are joined by a conical portion 5 and the die-like restriction 33<SP>1</SP>, 341 has a corresponding conical form. Various forms of piston units are described including one in which the fastener 101, Fig. 4, is connected by a threaded recess and spigot 51 to a holder 53 having a knurled shank 57 force fitted into a recess 58 of the piston 54.

IPC: B29C63/20
Filed: 1959-10-27
Abstract: 900,597. Coating with preformed thermoplastic coatings. SUNDT & CO. Ltd. Oct. 27, 1960 [Oct. 27, 1959], No. 36465/59. Class 93. Articles such as, for example, a handle for a broom, garden implement or mop are coated with a thermoplastic material by inserting the article into a sleeve of the thermoplastic material whilst the latter is maintained in an expanded condition by a suitable gaseous fluid. As shown, the thermoplastic is formed in a continuous length as a sleeve or tube 1 and stored on a drum 3. One end of the sleeve is connected to a compressed air supply via the spindle of the drum by a revolving connector (not shown). The air pressure is controlled by a valve 5. The free end is led through the jaws of a combined clamp 6 and guillotine 7 which is also operated by compressed air. With the valve allowing air to pass into the sleeving a plug 8 of aluminium or light alloy and of approximately the same diameter as the handle to be coated is inserted in the open end of the sleeve, one end of the article to be coated is placed behind the plug and the whole pushed into the expanded sleeve. The air supply is diverted to the clamp which closes on the plug; the clamp is formed with rubber jaws set slightly proud of the knives so that the plug is first gripped and as the air pressure increases the knife edges sever the sleeving, which contracts when the air pressure is cut off and grips the article tightly. The article is detached, any overlap heat sealed and trimmed and the operation repeated on further articles.

Abstract: 1276522 Control circuits for discharge lamps MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 21 July 1969 [23 July 1968 14 Aug 1968] 36647/69 Heading H2H [Also in Division H4] A discharge lamp has one hot negative electrode and two positive electrodes, an auxiliary discharge being generated between the negative electrode and one of the positive electrodes. A control arrangement operates to apply an intermittent D.C. voltage across the negative electrode and the other positive electrode in order to modulate the light output. In the embodiment shown in Fig. 5, the brilliance of a lamp 31 is controlled by pulse amplitude modulation. An abnormal glow discharge is maintained between the heated cathode 32 and auxiliary anode 34 by a source 45. The main discharge between the cathode 32 and main anode 33 is controlled by a modulator circuit 43, the input for which may be a video signal in a television system. An input pulse is stored in a capacitor 38 and amplified by transistors 35, 36 so that lighting current can flow to the lamp from source 49 through the transistor 36 and a brilliance control resistor 44. The lamp is switched off by applying a gating pulse to a thyristor 39 which then discharges the capacitor 38. Several lamps of different colours may be combined into a unit in a display device and modulated at high frequencies. In an alternative embodiment, Fig. 7 (not shown), the duration of the main discharge is controlled by the height of the input pulse, the arrangement including an R.C. time constant circuit, an amplifier and a Zener diode clipper. In another embodiment, Fig. 3 (not shown), the main discharge is controlled by a series combination of a thyristor and a switching transistor connected across the main electrodes and a D.C. source.
