Title: Improvements in the treatment of magnesium base alloys and the production of pressure die-castings therefrom
IPC: B22D21/00
Filed: 1944-06-23
Abstract: 578,977. Magnesium base alloys. STONE & CO., Ltd., J., PAYNE, R. J. M., and MURPHY, A. J. June 23,1944, Nos. 11966/44 and 15224/45. [Class 82 (i)] [Also in Group XXII] In the treatment of magnesium base alloys and the production of pressure die castings therefrom, beryllium is added to the alloy to restrict the oxidation of the alloy which is melted in a compartmented crucible with communication between the compartments below the normal surface of the molten alloy, the contents of one compartment being left without a flux covering. A magnesium base alloy suitable for pressure die casting contains aluminium from 8 per cent to 10 per cent and zinc up to 1 per cent, the beryllium being added to the extent of from 0.01 per cent to 0.10 per cent. One form of steel crucible a shown in Fig. 1 has a partition b defining a comparatively large compartment d over which a layer of flux c is maintained and a smaller compartment e without a flux covering. The compartments communicate at the bottom as indicated at f. Scum is periodically removed from the top of the alloy in the compartment e and alloy is ladled from this compartment to feed the die-casting machine. Additional metal for melting, together with discard from the casting machine, surplus metal from the ladle and rejected castings are put into the compartment d through the flux cover c. The partition is extended above the top of the crucible walls to prevent the accidental entry of flux into the smaller compartment. In modified forms the smaller compartment is formed by a cylindrical member suspended from a cross-bar above the crucible or standing on the bottom of the crucible and having -intercommunication openings at the lower end. In a further modification, Fig. 6, a cylinder g of the latter type is extended well above the top of the crucible and is provided with a cover to form above the surface of the alloy a closed chamber supplied with a gas such as sulphur dioxide or nitrogen further to reduce oxidation. Ladling may be effected by way of an opening m normally closed by a spring-operated or by a mechanically-operated door n.

Title: Pyrimidine derivatives and the manufacture thereof
IPC: F16C3/14
Filed: 1958-04-18
Abstract: The invention comprises compounds of the formula <FORM:0920412/IV(a)/1> wherein R1 is an alkyl group of 1-4 carbon atoms, R2 is hydrogen, isopropyl, an alkyl group of 4-6 carbon atoms or benzyl and R3, R4 and R5 are hydrogen or halogen e.g. bromine; when at least one of R3, R4 and R5 is halogen R2 may also be n-propyl.  The compounds are prepared by formylating a compound of the formula <FORM:0920412/IV(a)/2> wherein R6 has the values of R2 other than hydrogen and R7 is an alkyl group of 1-4 carbon atoms, condensing the product with guanidine to give a 2-amino-4-hydroxy-5benzyl-pyrimidine derivative, chlorinating e.g. with POCl3 and aminating.  Compounds wherein R2 is hydrogen are made by hydrogenolysis of a compound wherein R2 is a benzyl group. Compounds wherein one or more of R3, R4 and R5 are halogen atoms may be prepared by halogenating, e.g. brominating, the corresponding unsubstituted compound.  Hydrocinnamic esters of the formula II used as starting materials namely 3-methoxy-4isopropoxy-, 3-methoxy-4-butoxy-, 3-methoxy4-isoamyloxy-, 3-methoxy-4-propoxy-5-bromoand 3 - methoxy - 4 - butoxy-5-bromo-, hydrocinnamic acid ethyl esters are made by alkylating vanillin, or the appropriately substituted vanillin, in the 4-position, condensing the 3methoxy-4-alkoxy-benzaldehyde (or bromobenzaldehyde) obtained with malonic acid, esterifying the resulting corresponding substituted cinnamic acid to give the ethyl ester and reducing catalytically.

A flame desurfacing head comprises slotted nozzles 14 for directing a uniform flat stream 25 of oxidizing gas at an acute angle against a preheated surface 29 of a metal workpiece W, and a powder nozzle 34 associated with each gas nozzle for directing a substantially flat stream 45 of powder-laden gas at an acute angle into the oxidizing gas stream, said powder nozzle having an internal passage bounded by outwardly divergent side walls 36, Fig. 5 (not shown), and outwardly convergent upper and lower walls, the inlet conduit 38 of the powder nozzle opening into the internal passage through a rear portion of the upper wall 32, and the opposite lower wall portion exposed to impact from the entering powder particles being provided with hard erosion-resistant material 40. The apparatus is used in particular for desurfacing stainless steel using an adjuvant powder such as ferromanganese entrained in the carrier gas such as air, nitrogen or oxygen, supplied to the nozzles 34 through the pipes 38 which taper slightly towards the nozzle. Pre-heating oxygen and acetylene gas mixture is supplied to nozzle ports 16, 18 through mixers 22 and pipes 23. The desurfacing oxygen is supplied to the flat nozzles 14 through pipes 20, Fig. 1 (not shown). Slag is prevented from adhering to the sides of the workpiece by projecting jets of compressed air from tubes 52. Water is projected in a high pressure stream from a jet 55 across the surface of the workpiece ahead of the nozzles to wash away the slag into a shoot 57, Fig. 4 (not shown). The erosion-resistant material in the powder nozzle comprises inserts of sintered tungsten carbide 40 backed by rubber discs 42. The cutting angle between the oxygen stream 25 and the work surface 29 is 30 degrees and the entry angle of the powder tubes 38 into the nozzle passages 34 is 140 degrees. Cooling water for the nozzles 37 is supplied through a duct 48.

Abstract: 677,884. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. April 29, 1949 [May 6, .1948], No. 12489/48. Class 39 (i). A cold cathode gas. filled electric discharge tube comprises two electrode assemblies, each comprising two main gap discharge electrodes in the form of metal plates 5 having flat portions riveted to a mica plate 4 and mounted by means of lead-out rods 3 sealed in a glass press 2 and upturned channel section edges forming opposed rectangular discharge surfaces 6. The outer edges of the plates may be bent around the edges of the plate 4 to maintain accurate gap dimensions. A third rod 3 in each assembly protrudes through an aperture in the plate 4 and forms either an anode or a cathode trigger. In the latter case the plate 4 is spaced from the trigger by a distance less than the length of the cathode fall and functions as a field control plate to restrict the cathode glow as described in Specification 677,883, but if the trigger electrode is only to be used as an anode, clearance is not necessary. A sheet 8 of insulating material such as mica, supported by rods 9 prevents ionization coupling between the two assemblies. Gap dimensions are given which are suitable with a filling comprising a mixture containing hydrogen at a partial pressure of 35 mm. of mercury, and neon (with 1 per cent argon) at a partial pressure of 5 mm. of mercury.

The bushes 4 are flanged and moulded into the strip. The lower flanges 8 locate the strip along the slot. Alternatively, the strip itself is grooved to engage the edges of the slot. A hole 3 at the end of the slot permits removal of the strip. In use, the two end holes of a line are first drilled and two of the bushes are then registered with the holes by locating pins 10, 11, the bushes being chosen to have the same number of bushes between them as holes that are required. The plate 1 is raised clear of the work by rubber strips 9.
