Title: Electrical apparatus
IPC: H01F41/06
Filed: 1966-05-12
Abstract: 1,130,448. Coiling wire. WESTINGHOUSE ELECTRIC CORP. 12 May, 1966 [17 May, 1965], No. 21046/66. Heading B3E. [Also in Division H1] Insulated electrical conductor 30 (suitably of enamelled copper wire) is formed into turns on rotating mandrel 22 and forced off the mandrel into the space between rotating tubes 10, 11 by stationary guide 38, so that they progressively fill the space and make up a coil which is secured by casting an epoxy resin, or other liquid which sets or cures to form a, bonding means, with or without an inorganic filler, in the space between the tubes so that the coil and resin form a voidless assembly. The diameter of the turns formed on the mandrel is the arithmetic mean of the inner and outer diameters of the annular space between the tubes 10 and 11. Tubes 10 and 11 may be of stainless steel, coated with a mould-releasant such as silicone grease, or be of other material suitable for moulds to be removed after the bonding means is solid. Alternatively they may be of insulating material, such as pressboard or a laminated plastics material, and be a permanent part of the coil assembly. Optionally tubes 10 and 11 may be replaced by frustum-shaped insulating members between which there is an upwardstapering annular space. These may be applied to the cured coil, prepared in a mould whose annular diameters change progressively from its base to its head, with a constant arithmetic mean which is the diameter of the turns, or themselves be used as catcher tubes. The coil which results has a progressively decreasing number of turns upwards from its base to its last-formed upper part.

Filed: 1967-05-08
Abstract: 1,180,115. Automatic circuit breakers. A. B. RYPINSKI. 8 May, 1967, No. 21203/67. Heading H1N. An electromagnetic tripping device in an automatic circuit breaker comprises a coil 25 mounted within a U-shaped magnetic core 60 and an armature comprising an aluminium tube 40 movable rectilinearly through one arm of the core 60 and containing a magnetic core 45 and a magnetic plug 50 biased apart in the tube by a spring 47. On overload, the core 45 and plug 50 first move together and then the armature moves as a whole to turn an L-shaped lever 70 about its pivot 76, releasing it from a slide 85 which is moved up grooves 86 by the bias in a contact blade 30, opening contacts 33, 35. As lever 70 turns the operating handle 17 is released from an overcentre position and moves to the off position by means of a coiled torsion spring 103; lever 70 is biased upwards by a spring 98. In reclosing, the handle first pivots lever 70 about 76 to bring its tip 75 into engagement with the armature and its other tip 73 into engagement with a tongue 90 on the slide 85. Further movement drives lever 70 and slide 85 downwards together to close the contacts. Lever 70 is resilient, allowing the armature to move before the necessary tripping force is achieved. The blade 30 is doubled over the end of wire 27 of the coil and soldered in place. All parts are held in place by projections from the inner surfaces of the two-part moulded case. For different current ratings different coils 25 are wound with the same external dimensions so that they can be supported by the same projections. The other end 26 of the coil is attached to a bus-bar terminal 16. In a modification (Fig. 13, not shown) spring 103 is omitted, the handle is released by an extension 130 on the slide 85.

Title: Improvements in or relating to pressure responsive fluid-flow measuring instruments
IPC: G01F1/50
Filed: 1947-08-08
Abstract: 638,925. Fluid-pressure servomotor-control systems. ELECTROFLO METERS CO., Ltd. Aug. 8, 1947, No. 21824. Convention date, Sept. 8, 1941. [Class 135] A device for measuring a fluid flow in a conduit comprises a balance on which acts the differential pressure across a restriction in the conduit, the balance forming part of a first valve device of which the output pressure, besides re-acting back on the balance to recentre it, also acts on a fluid-pressure responsive device actuating a second valve, and the output pressure from this second valve acts on a fluidpressure responsive member so that the square root of the movement of this member reacts back on the control element of the second valve device. In an embodiment, the pressures upstream and downstream of a restriction in the conduit in which the flow is to be measured are applied to the two sides of a diaphragm 5, Fig. 1, the latter being connected to a beam 12. The pressure differential applied to the diaphragm can be varied by adjusting a valve 9 which controls an aperture interconnecting the two sides of the diaphragm. Beam 12 is loaded by weights 14 at one end and the other end carries a valve 15 controlling the pressure in a pressure supply line downstream of a restriction 17. The regulated pressure is applied to a diaphragm 18 which acts on the beam 12 to re-centre it and is also applied to a diaphragm 24 of a relay similar to the first control device and comprising a lever 26 actuated by the diaphragm and a valve 27 controlling the pressure in a pressure supply line downstream of a restriction 29. The regulated pressure from the relay is applied to a diaphragm 32 which acts on a lever 35 carrying a pointer to indicate the flow being measured. Lever 35 is connected by a link 39 to a lever 38, and a roller 36 on the end of lever 35 acts on a lever 37 also pivoted on lever 38. The movement given to lever 37 by lever 35 is communicated by an abutment 43 to a further lever 41, and from the latter through a spring 44 back on to lever 26 to provide follow-up. The movement given to lever 26 will be a square-root function of the movement of lever 35. Compensation for temperature variations may be given by mounting the seat for valve 27 on a pressuresupply tube mounted in the casing of the relay and having a differential thermal coefficient of expansion from the material of the casing. In a modification, the diaphragm 24 is replaced by a bellows 58, Fig. 3, and the lever and spring construction for giving a repeat-back is replaced by a spring-loaded lever 55 carrying the seat 54 for the regulating valve 56. Pressurefluid is led to the valve seat 54 past a restriction 65 and through a line 62. Specification 635,731, [Group XIX], is referred to.
