[Class 40 (viii)] [Also in Group XL (c)] In a wave-guide type crystal mixer, a wedge-shaped conductive element is placed between the input end of the guide and the crystal, and a dielectric vane coated with conductive dissipative material is placed in the guide beyond the crystal. A wedge-shaped conductive member 23, of length not less than the operating wavelength, extends across a broad side of the input guide 10. The wider end of the wedge-member 23 has a flat extension surrounding the mechanical support and electrical connections of the crystal unit 12. The terminal 20 of the crystal capsule 12 carries the cat's whisker 44, and fits into an extension of the inner conductor 18 of a coaxial socket 16. The silicon crystal 45 is embedded in metallic end 19 which is held in contact with the inner conductor 17 of coaxial socket 15, separated from the outer conductor 35 by dielectric bushing 40 and from the wave-guide wall by a dielectric washer 38. The material of the bushing 40 and washer 38 is so chosen that a high-frequency byepass capacitor is formed between metal end 19 and earth. The extension of the wedge-shaped element 23 has an end surface perpendicular to the broad wall of the guide, and the thin end of the wedge is conductively connected to the wall of the guide. The waveguide is closed by a wall 11 beyond the crystal and a dielectric vane 27, at least one wavelength long, is placed perpendicular to the broad sides of the guide, midway between the narrow sides. One edge of vane 27 has a slope opposite to that of wedge 23 and the surfaces and edge of the vane are coated with lossy resistive material such as graphite.

Filed: 1974-02-11
Abstract: 1456729 Cleaning printed circuit boards ELECTROVERT Ltd 11 Feb 1974 [5 March 1973] 6185/74 Heading F2N Printed circuit boards are cleaned, after having been fluxed and soldered, by resting each board substantially horizontally on a screen conveyer 30, a first plurality of spaced, high velocity coherent jets 25A of cleaning liquid being directed perpendicularly against the entire upper surface of the board. These coherent jets, i.e. having no interior bubbles &c., are sufficient to wash the board completely including those portions lying beneath components soldered thereon, and also maintain the board on the conveyer whilst a second plurality of coherent jets 25B are directed perpendicularly through the conveyer to clean the undersurface of the board. The jets emerge from upper and lower manifolds 20A, 20B, the nozzles of the upper manifold 20A overlapping, as shown, those of the lower manifold 20B. As described, some vibration of the conveyer 30 may be introduced by eccentric rollers 46 so as to slightly move each board and thereby enable the whole undersurface thereof to experience the direct force of jets 35B. A series of units 35 may be used, at least one using water as the cleaning liquid 41. A drying stage may be employed, air under pressure being directed against the upper and lower surfaces. In a further drying stage electrically heated air may be directed on to the boards. Air knives 40 adjacent inlet and outlet openings 37, 38 reduce splashing and mist, and "carry over" when a succession of units is employed.

Title: Method of producing zinc-coated steel articles and articles produced by such method
IPC: C23C28/02
Filed: 1966-02-11
Abstract: A steel surface is coated with zinc by electro-plating, hot dipping or vapour deposition and the zinc coated with aluminium by vapour deposition, e.g. by an electron beam.  The substrate is de-gassed by a high voltage discharge.  Prior to the coating with zinc, the steel may be first coated with copper, gold, silver or brass e.g. by ionic deposition from aqueous medium or electro-plating. After applying the aluminium the surface may be chromated e.g. with K2Cr2O7 solution. In an example, steel panels are cleaned cathodically at 50 amps./sq.ft. in a solution of sodium carbonate and hydroxide and trisodium phosphate, pickled in muriatic acid, and then Zn plated in a bath (pH 3) of ZnSO4 and (NH4)2SO4 at 20 amps./sq.ft.

Title: Improvements relating to multi-stage axial flow compressors
Inventor: PEARSON HARRY
IPC: F04D19/02
Filed: 1954-03-04
Abstract: 766,812. Axial-flow compressors. ROLLSROYCE, Ltd. March 4, 1955 [March 4, 1954], No. 6413/54. Drawings to Specification. Class 110 (1). One or more rotor stages at the inlet end of a multi-stage axial-flow compressor include a blade or a group or groups of blades differing in aerodynamic characteristics or arranged to produce different aerodynamic effects as compared with the remaining blades of the stage, whereby the bands of high and low velocity air into which the air flow tends to break down when the stages are wholly or partially stalled are stabilized angularly with respect to the blade or group or groups of blades so as to rotate at the same speed as the rotor. The bands would otherwise have rotated at a reduced speed of, for example, 30 to 50 per cent of that of the rotor, thereby subjecting both the rotor and stator blading to exciting loads due to the succession of high and low air velocities which might have given rise to forced vibration of the blading. In one embodiment, each of the first two stages of the compressor of a gas-turbine jet-propulsion engine has two diametrically opposed groups of six consecutive rotor blades which have a greater camber than the remaining rotor blades of the respective stage. Additional stages, for example up to a total of five stages, may be so arranged. In all cases, it is arranged that air passing through blades of increased camber in one stage passes through like blades in succeeding stages. The blades may differ in aerodynamic characteristics other than camber, for example twist or angular setting. Groups of blades of the same or differing aerodynamic form as the standard blades may differ from the latter in respect of spacing.

IPC: C22C43/00
Filed: 1947-03-10
Abstract: Irregularities in the physical and mechanical properties of extremely pure uranium, i.e. uranium containing less than 0.1 per cent of impurities, are reduced or substantially eliminated by adding to the uranium an alloying element or elements of small thermal neutron capture cross section in an amount which should not be less than 0.05 per cent in total and is insufficient to produce an increase in the total competitive neutron absorption exceeding 0.1 per cent.  The following are elements which may be added in amounts up to the indicated maximum percentages, Al 0.37, Si 0.36, P 0.32, Sn 0.56, Pb 4.0, Bi 4.0, Nb 0.15, Zn 0.17.  The uranium is subjected, in the molten state, to high vacuum to remove volatile impurities, the pressure is then raised and the required alloying elements are added as such or as alloys or as compounds which will yield the elements under the conditions of melting.  The Provisional Specification refers also to the use of Be up to 3.0 per cent.
