Patent GB-2460334-A (GB)
Title: Transformer having isolation means
Inventor: MILLER ANDREW
IPC: F21V23/04
Filed: 2009-05-26
Abstract: A transformer 2, particularly suitable for low voltage lighting 6, comprises a connector portion 10 for connecting the transformer to a wiring system 16, a converter portion 8 for converting a primary voltage to a secondary voltage and an isolation means 18, operable to isolate the converter portion from the connector portion while maintaining the electrical continuity of the wiring system. This allows the wiring system to be tested without damaging the transformer. The isolation means may be in the form of a latch having conductive and non-conductive portions movable between a first and second position. In the first position the converter is electrically connected to the wiring system, in the second position the converter is isolated from the wiring system but the live contacts 12, 12', neutral contacts 14, 14' and earth contacts 13, 13' are electrically connected to each other to maintain the continuity of the wiring system.

Title: Jet propulsion engines
IPC: B64C25/42
Filed: 1973-03-01
Abstract: 1416464 Propulsion jet thrust reversal SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 1 March 1973 [6 March 1972] 10002/73 Heading B7G [Also in Division F2] A jet propulsion engine, which in the forward thrust position discharges a gas flow to the rear, is located within a nacelle 8 with an after-body 9 having lateral openings 10 through which at least a major portion of the gas flow may be diverted with a forward component of velocity for thrust reversal, and those zones 11 of the after-body which are circumferentially between the openings 10 are provided with means for causing the external air flow Fe to break away from the wall of the nacelle during thrust reversal. It is stated that in the forward thrust position, because of the taper of the after-body, the external air flow is recompressed, giving a thrust (negative drag), and that this also occurs in the regions to the rear of the zones 11, reducing the braking effect, during thrust reversal. Therefore in the thrust reversal position air fi may be injected into the external air flow to cause it to break away, giving rise to lowpressure turbulence 21 and increasing drag. This air fi may be provided from circumferentially extending slots 15a-15d in the zones 11, of which the slots 15b, 15d are covered by the thrust-reversing obstacles 12 in the forward thrust position, Fig. 1 (not shown), and the slots 15a, 15c are closed by flaps 16 which are linked to toothed sectors 14 controlling the obstacles 12. Or, Fig. 2a (not shown), both the openings 10 and slots (115) may be uncovered in the thrust reversal position by an axially movable fairing (109). In both these embodiments the injected air is tapped from the main flow through the engine; alternatively, Fig. 3 (not shown), air bled from compressor (3) may be supplied to slots (215) in the zones 11 during thrust reversal. Alternatively the external air flow may be disturbed by flaps (315), Figs. 4, 5 (not shown), which are caused to protrude from the external wall of the after-body in the zones 11 during thrust reversal.

Abstract: 1377564 Semi-conductor devices WESTINGHOUSE ELECTRIC CORP 3 March 1972 [9 April 1971] 10050/72 Heading H1K Deleterious migration of contaminant ions such as sodium in a silicon oxide layer on a semiconductor body is prevented by doping the oxide with ions of Ba, Pb, Cr or Ca or their oxides in a concentration of 0À1-20% by volume. The oxide may perform a junction-passivating role but in the illustrated embodiment it constitutes the gate insulation 20 of a thin film IGFET. Other materials employed in the device include Au, Ag, Al, Ni or alloys thereof for the source and drain electrodes 14, 16, Al, Cu, Sn, Ag, Au or Pt for the gate electrode 18 and Te, CdS, CdSe, Si, InAs, GaAs, SnO or PbTe for the semi-conductor layer 18. All layers are preferably formed by vacuum evaporation, but sputtering or pyrolytic decomposition may also be used to deposit the doped oxide layer 20. The substrate 12 may be rigid, for example of glass, ruby, alumina or ceramic, but various flexible substrate materials such as paper, plastics materials or coated metal foils may also be used. The completed device may be sealed in a silicon oxide coating. An apparatus is described for forming a series of such devices on a flexible strip by sequential masked evaporation stages in a vacuum.

Abstract: 677,665. Gear-grinding. CRAVEN BROS. (MANCHESTER), Ltd., and OWEN, W. March 8, 1951 [April 25, 1950], No. 10138/50. Class 83 (iii). [Also in Group XXIII] Indexing.-A gear-grinding machine comprises indexing means consisting of an intermittently driven shaft m, a differential gear l of which one sun wheel drives a change-gear shaft k while the other is driven by the shaft m, a worm shaft h<SP>1</SP> driven by the shaft k through indexing change gears and driving the work through a worm-wheel g, and prime' change gears p, driven by the shaft h<SP>1</SP> through reversible gearing r and driving the planet carrier of the differential gear l so as to cause the revolutions of the shaft m, in relation to those of the shaft k, to be increased or decreased by a small number. The worm h is mounted, with its controlling means, on an arm f journalled on the hub of the worm-wheel g keyed to the shaft carrying the work-gear a. When helical teeth are to be ground, the arm f is rocked by tapes d carried on a slide b, while the grinding-wheel is moved axially of the gear a. At the end of each traverse of the wheel across a tooth, a motor s is automatically started and a plunger v is withdrawn from a slot in a plate w to allow the shaft m to make one revolution before the plunger is re-engaged. Thus by choosing the indexing gears to give an overall ratio to the nearest 10,. any desired prime or other number of revolutions of the shaft m per revolution of the work may be obtained, the prime gear being chosen to supply the additional number up to 5, which number is added or subtracted according to the setting of the clutch of the gears r. A numerical example is given in the Specification.

These excess quantities may pass through a third heat exchanger C during the first and second stages shown in Fig. 1a, and during the second and third stages shown in, Fig. 1b, In a modification the excess quantities of K and W traverse passages outside the regenerators A, B.

Abstract: 481,336. Colour kinematography &c. BOCCA, C., and AMATI, L. April 9, 1937, No. 10235. [Class 97 (i)] In the production of multi-coloured projected images by the method described in Specification 423,677, a filter is employed during projection comprising a central opaque disc E, pairs of diametrically-opposed coloured zones A, B, C, and intervening transparent colourless zones D. The disc E prevents the passage of un-diffracted light. The zones A, B, C are each of the colour appropriate to one of the gratings constituting the colour-record images, and are in such positions that the diffracted images of the light source formed by a single grating only are formed on them. The gratings also form images which are diffracted by two or more gratings, and such images fall on the zones D. The intensity of the colours of the zones A, B, C may be increased to counteract the effect of the uncoloured light passing through the zones D, and the relief of the gratings constituting the colour-record images may be as high as possible.
