Title: Electrical isolating circuits
IPC: H02M3/28
Filed: 1975-05-21
Abstract: 1506633 Voltage measuring N SENGER 21 May 1975 [21 May 1974 19 Nov 1974 14 Feb 1975 24 Feb 1975] 22016/75 Heading G1U [Also in Division H2] An electrical isolating circuit has an input port for connection to one circuit and an output port for connection to another circuit and comprises a rectifier connected to the input port, a chopper for chopping the rectified output to produce an A.C. output signal of chopper frequency, a filter circuit connected to the chopper output for passing signals at the chopper frequency while preventing signals of a lower frequency from passing, and another rectifier for rectifying signals passed through the filter for delivery to the output port, the arrangement being such that for signals of the lower frequency, the impedance seen looking into one of the ports is substantially independant of any external impedance connected across the other of the ports. The embodiment shown in Fig. 3 may be connected to the input and/or output of a conventional capacitive voltage transformation circuit, Fig. 1 (not shown) to isolate circuits connected to this voltage transformer from the impedance changes occurring when the capacitors switch between series and parallel. In Fig. 3 alternating input voltage U e  of frequency f 1  is applied to rectifier 240, whose output is chopped in circuit 241 at a frequency f 2  much greater than f 1 . The chopped output is applied to filter circuit 244, the values of whose components C1 ... C4 and L together with the frequency f 2 , are chosen so that the impedance seen looking into the input or output of the isolating circuit is substantially independent of any impedance connected across the output or input respectively. The output of filter 244 is applied to rectifier 245, which feeds a polarity correcting circuit (or commutating switch arrangement) 246, whose output is applied to a low pass filter 247 which removes the chopping frequency f 2  and its harmonies to produce an output signal whose frequency f a  is the same as f 1 . The theoretical basis of the isolating circuits is explained assuming a very small impedance of capacitors C1 ... C4 at the frequency f 2  and an inductance L which provides a short circuit to earth at the frequency f 1 . If the input voltage U e  is a uni-directional one (U c ), members 246, 247 are omitted and smoothing capacitors (250, 251) are connected across the outputs of rectifiers 240, 245, Fig. 4 (not shown).

Title: Improvements in cleats for securing and supporting cables, pipes and the like
Inventor: CHAPLIN SYDNEY FRANK
IPC: F16L3/23
Filed: 1954-07-28
Abstract: 758,160. Wall and like brackets. LONDON ENGINEERS PATTERN CO., Ltd. June 3, 1955 [July 28, 1954], No. 22064/54. Class 52(5). [Also in Groups XXV and XXXVI] A cleat for securing and supporting cables, pipes and the like comprises a base plate 1 adapted to be bolted or otherwise secured to a surface and having extending therefrom a pair of clamping arms 2, 3, one arm 2 being pivoted to the base plate to swing away freely from the second arm 3 and the second arm 3 being separate from and secured to the base plate by means rendering the arm substantially immovable when attached to the base plate, the arms being adapted to be drawn together to embrace a cable, pipe or the like or a bundle thereof. As shown, each of the arms is formed with a knuckle lug 10 and each is received between a pair of lugs 9 on the base plate, a pin passing through apertures in the lugs 9 and 10. The arm 2 can pivot freely but pivoting of the arm 3 is prevented by providing a tongue 11 on the knuckle lug 10 which projects into a slot or recess 12 in the base plate 1. The arm 3 can therefore only rock to a very limited extent. Each arm has an apertured lug 13 at its free end the lugs being connected together by a bolt 14. In a modification the base plate is formed with a single lug for each arm and the arms each have two knuckle lugs. The knuckle lugs on the arm 2 are rounded so that the arm can pivot freely but the knuckle lugs on the arm 3 have flat faces which abut similar flat faces formed on the base plate to permit the limited rocking movement of the arm 3.

Title: Method of joining
Inventor: POUNDER DONALD WHITWORTH
IPC: B29C65/04
Filed: 1964-05-28
Abstract: 1,100,131. Seaming non-metallic sheet material. DUNLOP RUBBER CO. Ltd. 12 May, 1965 [28 May, 1964], No. 22166/64. Heading B5K. Two or more sheets of a non-thermoplastic non-cellular polyurethane composition are joined by assembling the pieces in overlapping or abutting relationship at the position of the desired joint and passing a high-frequency alternating electric current through the sheets to form the joint. The invention is applicable to joining sheets shaped from sheet material, e.g. dished or cylindrical sheets. Preferably, the sheet material is in the form of a textile fabric coated with the polyurethane composition. The textile fabric may be a woven fabric, a non-woven felt, a cord fabric containing little or no weft, or two or more crossed plies of such a cord fabric. Specified fibrous materials of the fabric are cotton, linen, polyamides such as nylon, regenerated cellulose, poly(ethylene glycol terephthalate), polyvinyl chloride, polyethylene or natural or synthetic rubber. Alternatively, at least one sheet may comprise a film of the polyurethane composition. The polyurethane composition may be prepared by making a liquid polyurethane prepolymer or a solution of a prepolymer in a solvent therefor, and causing the prepolymer to become cross-linked. The prepolymers are usually obtained by reacting a polymer containing active hydrogen atoms such as polyol, e.g. a polyether polyol, a polythioether polyol, a polyester polyol, a polyesteramide polyol or a polyamide polyol, with a stiochiometrical excess of an organic polyisocyanate or polyisothiocyanate. The prepolymers can be cross-linked by a cross-linking agent which may be water or an organic polyfunctional compound such as a polyol having at least three hydroxyl groups, a polyamine or methylene-bis-orthochloraniline. Typical polyurethane prepolymers are those prepared from a polyglycol such as poly-1,4- tetramethylene glycol or polypropylene glycol. Alternatively, the non-cellular non-thermoplastic polyurethane may be prepared by curing a polyurethane rubber composition, e.g. by reaction with isocyanates, e.g. a tolylene diisocyanate dimer, peroxides, e.g. dicumyl peroxide, or sulphur. The dielectric welding machines used may include means for varying the intensity of the current and means for adjusting the distance between the electrodes which may be shaped as rods, laths, discs, sheets or combinations of these shapes. Preferably, during passage of the electric current, the distance between the electrodes is decreased until the thickness of the assembly at the portion of the desired joint is decreased by about half. In one embodiment, Fig. 3, two sheets 13, 14 are joined by electrodes 15, 16, each in the form of a brass lath and attached to insulated jaws 17, 18, respectively, of a hand-operated dielectric welding tool. The pressure exerted by the electrodes on the sheets 13, 14 can be varied by varying the hand pressure on an insulated grip 19 fixed to the jaw 17 on the opposite side of a pivot 20.
