Patent GB-892408-A (GB)
Title: Substantially constant-frequency alternating current generator, with variable-speed drive
Inventor: BESSIERE PIERRE ETIENNE
IPC: H02K7/00
Filed: 1960-04-14
Abstract: 892,408. Driving generators; transmitting mechanical power. PRECISION MECANIQUE LABINAL. April 14, 1960, No. 13492/60. Classes 35 and 38 (4). An A.C. generator is driven from an I.C. engine directly at cruising speed and through step-up gearing at idling speed so that at both speeds the engine speed regulator provides the speed regulation for the generator. In the form shown in Fig. 1, the A.C. generator comprises two separate alternators, 1 which is mounted directly on the engine driven shaft, 2 for cruising speed operation, and 8 which is arranged to be driven through step-up gearing 3 when an electromagnetic clutch 5 is energized, this clutch also serving to regulate the speed during the transition speeds. The connection change-over from one alternator to the other is controlled by a relay which may be linked to the engine fuel control or controlled by tachometric means. In a modification (Fig. 4, not shown), the main alternator may be used at both speeds, a centrifugally disengaged clutch and a free-wheel clutch coming into operation at the higher speed to disengage it from the gear drive and lock it directly to the shaft. The second alternator is driven through the gear and clutch as before and is only used during the short transition speed periods. If desired, the second alternator may be dispensed with, and the clutch used to regulate the main machine at the transition speeds (Figs. 5 and 6, not shown).

IPC: F23M5/00
Filed: 1961-04-14
Abstract: 929,068. Furnaces. EDWIN DANKS & CO. (OLDBURY) Ltd. April 12, 1962 [April 14, 1961], No. 13502/61. Class 51 (1). In a shell type boiler having an internal flue 2, the firing end of the flue is provided over an upper portion thereof with a protective screen of refractory material in the form of an arch 1 of refractory bricks 3, the ends of the arch resting on metal shelves 4 welded to the flue. To hold the bricks in position should the natural stability of the arch be destroyed and to prevent their longitudinal displacement, for example, when slicing slag from the arch, hangers 5 are welded to the flue in circumferential rows, each hanger having oppositely projecting lugs 7 which respectively co-operate with slots 10 in adjacent bricks 3. The hangers increase slightly in length from the shelves 4 to the arch centre to provide an expansion gap 8 between the arch and flue. The centre space 14 through which the bricks are passed for threading on to the hangers is filled with plastic refractory material.

Abstract: 1,254,889. Welding by pressure; electromagnetic forming. INDUSTRIAL MAGNETICS Inc. 14 March, 1969 [1 April, 1968], No. 13650/69. Headings B3Q and B3R. In a forming method, members are placed in contact with each other and if the members are not conductive conductors attached to the members are placed in contact with each other, an induction coil is placed adjacent the members and a forming current is passed through the coil to induce in the members, if conductive, or in the conductors, currents flowing in the same direction parallel to each other and to the interface between the members, the currents causing the members if conductive or the conductors to be forced towards each other to effect forming of the members. Two stainless steel pipes 11, 12 are abutted at interface 13 and are tightly surrounded by a stainless steel sleeve 14 which defines interfaces 15, 17 with the pipes. An induction coil assembly 10 is arranged about the pipe and sleeve and comprises an outside sleeve 20 of P.T.F.E., end plates 22, 24 and an inner sleeve 26 of ceramic aluminium silicon magnesium and within the space defined by these plates and sleeves a two-turn hollow copper coil 28 embedded in epoxy resin. Each turn of the coil 28 surrounds a copper ring 30 and the ends of the coil 27, 29 extend out through the sleeve 20 for connection to cooling water and current. Pipes 41 supply argon to passages 40, 44 in the assembly 10 for supply to the gap 46 between the assembly 10 and the workpieces. In operation a high frequency current of 10<SP>4</SP> Hertz is supplied from a motor generator circuit to the coil 28 to heat the workpieces inductively and then the motor generator circuit is disconnected and a charged capacitor bank is connected to the coil to induce currents in the pipe and sleeve which draw the pipe axially together and the pipe and sleeve together. A second cycle of heating and pressure applicator may be applied and argon is supplied during the process.

Title: Improved means for testing the products of combustion
IPC: G01N27/16
Filed: 1931-05-09
Abstract: <PICT:0378425/III/1> <PICT:0378425/III/2> A device for testing products of combustion (particularly the exhaust gases of internal-combustion engines) comprises catalytic and non-catalytic wires arranged e.g. in a Wheatstone bridge, and means for simultaneously controlling the activation of the catalytic elements and the admission of the gas to be tested. Fig. 7 is a diagrammatic illustration showing the Wheatstone bridge composed of catalytic wires 36 and non-catalytic wires 38, to which current is supplied from the battery 62 either directly through the wire 68 or through a ballast coil or other current limiting means 84.  Contacts 70, 72, 76 co-operate with a contact 78<1> on the lever controlling the valve 118 in such a manner that the initial movement of the lever passes current directly to the catalytic elements to heat them before the valve opens; further movement diverts the current to the elements through the ballast coil and also opens the valve admitting the gas to the testing device.  The latter, Fig. 1, comprises a jet 10 through which the gas is admitted to a venturi tube 12 where it is mixed with air drawn in through the pipe 52.  An annular shield 18 protects the catalytic elements from direct gas currents.  The products of combustion escape by way of the space 26 and the pipe 50, which is equal in length to the pipe 52 to neutralize varying air currents outside the apparatus.
