Title: Improvements relating to thermionic valves
Inventor: PEARSON NORMAN EDWARD HUGO
IPC: H01J19/38
Filed: 1959-03-13
Abstract: 916,971. Thermionic valves. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 2, 1960 [March 13, 1959], No. 8856/59. Class 39 (1). In a thermionic valve comprising electrodes having ends fitting into apertures in upper and lower insulating cross-plates 2, a metallic shield 8 is mounted on the top face of the upper insulating plate and extends over the ends of the electrodes so as to screen the upper end of the valve envelope, in which is mounted a top anode connection, from electrons passing through apertures in the insulating plate, and thereby avoid spurious signals in the anode circuit. The shield 8 is also provided with tabs 13 extending downwardly through plate 2 to minimize the escape of electrons from the underside of the plate 2. The shield 8 may be located by lugs 9-11 extending through the plate 2 from the beamforming electrode of a tetrode, Fig. 1 (not shown), and the tabs 13 preferably engage this electrode.

Abstract: 1,141,061. Forging manipulators. DAVY & UNITED ENG. CO. Ltd. 25 Feb., 1966 [2 March, 1965; 3 Jan., 1966], Nos. 8901/66 and 124/66. Heading B3H. A forging manipulator wherein the carriage moves continuously during forging, has its peel connected to a single-acting piston/cylinder assembly which restores the peel to its datum position when the forging is released. The peel 17, Fig. 1, is connected to a cylinder body 15 containing a piston-rod 12 secured to the manipulator carriage 14. Slidable upon rod 12 between shoulders 55, 55a is a piston 43 which also slides in an enlarged central part of the cylinder between abutments 45, 45a. Cylinder port 47 is connected to exhaust and cylinder port 48 may be connected to a pressure liquid source by means controlled by the forging tools. An annular projection 50 on the piston enters cylinder end bore 21 for cushioning the end of the piston stroke, Fig. 3 (not shown); stops are 60 provided on the opposite end of the piston. The manipulator is operative when forging in either direction. In a modification the right-hand side of the piston may be open to pressure continuously, for biasing the peel to its datum position, and work in conjunction with an accumulator. Other embodiments are described, Figs. 6, 7, 8 (not shown), using two pairs of parallel cylinder assemblies (64), (65) containing pistons (67), (68) connected respectively to the peel and the carriage. Hydraulic control systems are described. In a further embodiment, Fig. 9 (not shown), three parallel cylinders are used. The manipulator may also provide vertical movement for the workpiece. Reference has been directed by the Comptroller to Specification 898,738.

The covering layer may consist of glycerine, ethylene-glycol, chloral hydrate, &c. in aqueous solution, aqueous alcoholic solution &c. Gum arabic, tragacanth, gelatine, &c. may be added to the solution, and also, if desired, cane sugar. The covering layer may comprise : gum arabic, 40 grams; glycerine, 40 grams; sugar, 100 -grams; alcohol, 300 grams; water, 520 grams, and such -solution may be applied by brushing, dipping, spraying &c. to the dry or soft under-layer. The colouring solution may comprise metals, such as gold, silver, &c., or metal oxides &c. colloidally dissolved, with the additon of resins &c., in oils such as oil of turpentine or oil of lavender. The coated article is allowed to stand for some time before firing, or if desired the article may be pre-heated. The covering layers may contain metal salts &c. to produce colours which are different from the colour of the lustre, and in such cases the ground layer may comprise colourless resin-oil mixtures.

Abstract: 1,206,023. Closing packages. MAHAFFY & HARDER ENG. CO. 23 Feb., 1968 [2 March, 1967], No. 9028/68. Heading B8C. Semi rigid plastics cup-shaped receptacles containing articles, e.g. meat-slices, are conveyed below operating stations where a flexible web is heat-sealed to their mouth flanges to form a cover and stretched permanently to form side walls and a central face, the face being plunged into the receptacle to abut the upper surface of the articles contained therein, the receptacles then being evacuated and if desired, gas-filled. A web in which cup-shaped receptacles 12 containing articles 16, have been drawn e.g. by vacuum, in transverse rows or singly, is conveyed in trays 10. A plastics web 24 is heat-sealed to the cup mouth flanges at a station A, while a central section is suctionally adhered to a thermally insulated member 30 so that only an annular area against a sloping roof member 32 is also heated during sealing. While the annular area is still soft side walls are formed at a station B by suctionally moulding the web in a die 20, which is water-cooled to minimize "creep-back". A spring-loaded plunger 40 then pushes the cover into the receptacle so that the central face 37 abuts articles 16. The receptacles are evacuated at station C by means of a web lifter, described in U.S. Patent 3,061,984, which operates through a slit 54, Fig. 2 (showing a pair of receptacles) to create evacuation passages, the chamber in the die 27 is evacuated sumultaneously to minimize the pressure differential. The web lifter is withdrawn after evacuation and the slit 54 heat-sealed. The chamber 22 is then opened to atmospheric pressure which presses the web against the articles. Resilient pads 60 may be provided to prevent the inrushing air from distorting the cover.

Title: Complex compounds and their use in the separation of alkyl aluminium compounds from mixtures
IPC: C07C2/88
Filed: 1961-03-15
Abstract: The invention comprises complex compounds of alkyl aluminium compounds and alkali metal azides of formula nAlR3.1MN3 wherein n has a value between 1 and 2,1, R is an aliphatic radical and M stands for an alkali metal.  When M is Na, the complexes are 1,76 mol of AlR3 to 1 of NaN3, and 2,1 mol AlR3 to 1 mol NaN3 : when M is K, the complexes are 1:1 and 2:1.  The complexes are liquids, stable to heat, immiscible with hydrocarbons and sparingly soluble in aromatic hydrocarbons.  At high temperatures in vacuo they can be split into their components, the higher compound giving first the lower and then the individual compounds.  They may be used in separating trialkyl aluminium compounds from mixtures with other alkyl metal compounds, for example tetraalkyl lead compounds. Specification 777,152 is referred to.
