Title: Improvements in and relating to remote control installations
IPC: H02J13/00
Filed: 1936-06-09
Abstract: 461,482. Remote -control systems. SIEMENS-SCHUCKERTWERKE AKT.-GES. June 9, 1936, No. 16156. Convention date, June 15, 1935. [Class 40 (i)] In a system in which a frequency superposed on supply mains is used to control remote apparatus, the control is effected at the termination of the frequency pulse. When the frequency is applied to the mains N, the tuned circuit E, C causes reed 1 to vibrate so that lever 5 is oscillated and contacts 7, 8 close to allow relay 9 to pull up. Relay 11 energizes and its armature 12 holds contacts 7, 8 closed. When the control pulse terminates relay 11 de-energizes, but the armature of relay 9 is delayed, by means such as an air brake, for sufficient time to allow relay 14 to energize and lock. Contacts of relay 14 close the circuit to the controlled unit. The locking circuit of relay 14 may be opened by a circuit tuned to a different frequency which operates reed 4 and so contacts 160 or by a time switch operated by the controlled unit which opens contacts 161 a predetermined time after the control circuit is closed by relay 14. In an alternative arrangement, the lever 5 is rotated step-by-step by ratchet mechanism operated by the control frequency and is reset by a further ratchet mechanism operated by the resetting frequency.

Title: Improvements in or relating to ordnance sighting apparatus
IPC: F41G1/393
Filed: 1918-10-10
Abstract: 141,392. Dawson, Sir A. T., and Buckham, Sir G. T. Oct. 10, 1918. Sights.-Relates to guns not having an independent line of sight, and consists in actuating the sight by a hand-wheel, or other member fixed on the gun carriage, through mechanism forming a positive drive of shafts and gear-wheels from which all universal joints are eliminated, so that the setting of the sight is independent of the movement of the gun in elevation. In the form shown in Fig. 1, the sight-bracket C, pivoted coaxially with the gun trunnions, is adapted to be elevated by a pinion C<3> mounted on the gun cradle and driven from a hand-wheel E mounted in a fixed position on the gun carriage A, through gearing comprising a shaft E<1> and a worm E<2> meshing with a worm-wheel mounted on a shaft carried by a bracket E<4x> on the gun carriage, the latter shaft also carrying a bevel wheel E<3> meshing with a bevel-wheel e<3> connected through a telescopic drive-shaft e<5> with bevel-gearing e<4>, E<4> connected to the sight-elevating pinion C'. The bevel-wheels are all equal in size, and the distances between the axis C<1> and the axes of the bevel-wheels E<3>, E<4> are equal, so that any movement of the gun in elevation will not disturb the angular relation of the pinion C<3> to the line joining it to the pivot C<1>, and will therefore not affect the setting of the sight. Two such devices may be employed, one for range and the other for vertical deflexion. A similar device, an example of which is described, may be employed for horizontal deflexion.

Abstract: 876,457. Generating combustion products under pressure. AVCO CORPORATION. May 12, 1960 [Sept. 4, 1959], No. 16772/60. Class 51 (1). [Also in Group XXVI] Combustion equipment for a gas-turbine engine comprises an air chamber and air scoops for directing air into the combustion products for cooling and diluting purposes and a plurality of vanes is provided in the chamber to form curved channels through which the air flows, the scoops being so disposed within the channels as to scoop air for dilution purposes from the lower velocity streams of air flowing in the curved channels, the higher velocity streams of air flowing in the channels flowing past the scoops and being utilized in the combustion process. In the gas-turbine engine shown, air is delivered by the compressor, which comprises axial-flow stages 14 and a centrifugal stage 18, into a diffusion passage 20 which opens into an axially directed annular air chamber 22 disposed around the annular flame tube 25. Curved vanes 21a are disposed within the air chamber 22 and extend substantially axially therein as shown in Fig. 3, forming curved air passages 21b. The air streams flowing in the inner portions of the curved passages are at lower velocity than those streams in the outer portions of the passages and scoop assemblies 26 are disposed so as to intercept the streams of lower velocity and to discharge them into the flame tube in the same direction as the flow of combustion gases therein. These streams of air constitute dilution air which cools and dilutes the combustion gases. The air streams of higher velocity are not intercepted by the scoops and they flow on into the annular space 22a around the upstream end of the annular flame tube which they enter through the air inlets 29a, 29b, 29c. These air streams constitute air for supporting combustion of fuel supplied through the injection devices 29. The diluted mixture of combustion gases and air discharges through the duct 32 where its direction of flow is reversed and then flows first through the compressor driving turbine 34, then through the separate power turbine 35 finally discharging at 38.

Title: Glass bodies provided with colored layers and a method for producing the same
IPC: G02B5/22
Filed: 1959-05-15
Abstract: 915,870. Light filters. ZEISS-STIFTUNG, CARL, [trading as ZEISS, C. [Firm of]]. May 15, 1959 [May 21, 1958], No. 16833/59. Class 97 (1). [Also in Group II] A light filter or coloured glass is produced by depositing on a transparent colourless substrate an interference-free layer comprising at least two different materials, one being colourless and of lower refractive index than the substrate, the other being a metal or metal compound to give selective absorption and of high refractive index than the substrate, the distribution of the materials in the layer being such that the resultant effective refractive index of the layer at its boundaries with the substrate and the air is approximately equal to that of the substrate but is greater at the centre of the layer, as indicated by the curve A in Fig. 1. The height and width of this curve can be chosen for any desired degree of absorption, the actual layer thickness being limited to a few mid-spectrum wavelengths (for good adhesion to the substrate). The layers are normally deposited by thermal evaporation in vacuo using either a separate independently - controlled source for each layer component (Fig. 2); or by using a single evaporating source for both components and suitably controlling its temperature to be higher for increased deposition of the high index component (which usually has the higher melting-point), or lower for increasing the proportion of the low-index component of lower melting-point. Suitable low index substances include the fluorides of cerium, thorium, and magnesium, or silicon dioxide; high index substances include iron, nickel, manganese or chromium and the lower oxides of niobium, tantalum or titanium.
