Abstract: 441,823. Aeroplane engine mounting; reducing surface friction. RENAULT, L., 8, Avenue Emile-Zola, Billancourt, Seine, France. Oct. 3, 1935, No. 27364. Convention date, Dec. 12, 1934. [Class 4] Aircraft engines and in particular engines having radial cylinders disposed in a horizontal star are enclosed by a casing or envelope disposed in the deep part of a wing, the casing having an opening at its forward lower part for the admission of air and an opening at its upper part farther toward the rear of the wing for the exit of air, the arrangement being such that cooling air driven into the forward opening for example by the air-screw will circulate around the engine and leave the casing through the rear upper opening. The Figure shows a horizontal radial engine 2 driving an air-screw 6 through gearing 4 and disposed in a cut-away portion of the leading edge of the wing 1. The engine is enclosed by a casing 7 which is open at 8 to receive part of the air-screw slipstream and at 10 to discharge the cooling air in a zone of low pressure. A deflector 9 is fitted in opening 8. The carburetter and cylinders of the engine are disposed directly in the air blast. It is stated that an increased lift per unit area of the wing is obtained by reason of the heated air stream flowing over the extrados surface at high velocity.

Title: Electron beam apparatus
IPC: H01J29/46
Filed: 1968-06-10
Abstract: 1,213,738. Electron beam apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 10 June, 1968 [30 June, 1967], No. 27411/68. Heading H1D. An electron beam apparatus of the type described in Specification 1,162,732 is provided with a plurality of apertured diaphragms 27a spaced along the axis and each connected to earth through a resistance (35, Fig. 1, not shown) to provide a signal indicative of the intercepted current, thereby allowing any interruption of the beam to be detected and located. Each diaphragm is mounted adjacent but insulated from a sleeve 45 provided with heating coils 55 so that the diaphragm may be heated by radiation from the sleeve 45 to an operating temperature of 300 C.; this prevents the build-up of contaminants on the diaphragm and thereby reduces the diameter of the final focused spot (Fig. 5, not shown). The diaphragm is connected to a spring contact 39 adapted to cooperate with a fixed contact (49, Fig. 2, not shown) in a non-magnetic cylinder (23) in which the diaphragm assembly is mounted, and similar connections are made to the heating coils. The tube specifically described (Fig. 1, not shown) includes a data storage target (9) which is provided with an aperture aligned with a semi-conductor diode sensing element (37) for collecting the beam current. The beam is modulated by a pair of electrostatic deflection plates (32, 33) co-operating with a final apertured diaphragm, and is subsequently scanned over the target by a deflection coil (31).

Title: Process for improving the surface of workpieces composed of aluminium-base alloys
IPC: C22C21/06
Filed: 1936-10-14
Abstract: The resistance to corrosion of work-pieces of aluminium alloys containing 3-16 per cent of magnesium is increased by subjecting the work-pieces to a heat-treatment in a solid state, in contact with an oxidizing medium at temperatures and for a time sufficient to cause, by intracrystalline diffusion, the formation of a superficial zone at least 0,1 mm. thick, having an average magnesium content not exceeding 2 per cent.  The heat-treatment may be carried out in an atmosphere of oxidizing gas for at least 3 days, e.g. in air at a temperature of 440 DEG  C. or in a fused saline bath, which may consist wholly or mainly of alkaline dichromates or nitrates for at least 8 hours.  The temperature of the saline bath may be 460 DEG  C. If the alloy contains a heterogeneous component rich in magnesium, the alloy is first homogenized, e.g. at 460 DEG  C. before being subjected to the heat-treatment.  Reference has been directed by the Comptroller to Specification 448,944.

Filed: 1948-10-28
Abstract: 652,577. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and RALPH, F. E. Oct. 28, 1948, No. 28026. [Class 40 (iv)] Apparatus for testing the outgoing loop conditions of a selector-repeater or an auto-to-auto repeater determines whether the direct loop imposed during impulsing is replaced by a resistance loop and whether that in turn is replaced by a loop containing inductance. The selector-repeater shown in Fig. 2 has its last outlet wired to the test equipment of Fig. 1. After a number of other tests, the test switch TA reaches a position in which a loop is presented to line relay A. Relay CX energizes momentarily during the operating period of CY and delivers a single impulse to A. Relay CY connects up Z and a marginal relay X is connected to the outgoing loop. When dialling relay C (not shown) goes back, the short-circuit across relays D, I is replaced by a resistance shunt which is removed by the subsequent release of CA (not shown). Relay X therefore energizes and then falls back, whereupon the operation of Y connects Z to the loop, its operating circuit being opened. If X fails to release, or if Z fails to hold over the loop, stepping of the test wiper TA is prevented and the nature of the fault is indicated by lamps:
