Title: Process and apparatus for the manufacture of particulate refractories
IPC: C01B33/06
Filed: 1962-04-16
Abstract: <PICT:0985943/C1/1> Particulate refractory materials e.g. boron nitride and silicon carbide, of submicron size are made by feeding at least one of the reactants as a solid into a reaction chamber, drawing a high temperature arc between non-consumable electrodes in the reaction chamber to vaporize the solid reactant, and withdrawing the products therefrom.  The solid reactant may be pelletized in stoichiometric proportions or finely divided.  Silicon carbide may be made from a mixture of silica and carbon made into pellets with a phenolic resin as a binder, whilst boron nitride may be made by the reaction of boric oxide and carbon with ammonia.  The arc may be drawn between the wall of the chamber and the non-consumable electrode.  In one embodiment, Fig. 1, water-cooled steel casing 23 surrounds reaction chamber 20 which contains wall 22 and hearth 21 both of graphite, the casing being attached by 26 through water-cooled base 24 to hearth 21 while the annular space 34 is filled with high-temperature insulating material e.g. powdered carbon, and closed by a tapered ring 36 of solid graphite.  Lead 33 forms the electrical connection to the chamber. A steel top 37 fastened by insulated bolts to casing flange 40 is electrically insulated by an annular washer 38 from the casing.  Top 37 has an inlet tube 42 connected to a storage chamber with automatic feed mechanism and a sight tube 41.  A hollow electrode 43 e.g. of copper with a graphite tip 44, and O-ring seal 49 is cooled by water circulated down tube 45 and back up to 47.  Electrical connection to the electrode is made by 50 while coupling 48 provides means for rotating and lowering or raising the electrode.  The tip 44 is controlled so that it is always closer to the bottom wall than to the side walls.  Tubes 51 of graphite or metal and 54 carry the effluent to at least one cyclone after which the fines may be filtered off or returned to the furnace directly or a storage chamber.  A modified form of apparatus for use when one reactant is a gas or vapour is also described where the gas is supplied to the reaction chamber by a shroud surrounding the electrode. The product may be purified by oxidation to remove carbon or leached with alkali or with hydrofluoric acid to remove any excess of silica or fibrous material followed by washing, centrifuging and drying.  The manufacture of refractory carbides, nitrides, borides, silicides and oxides is also referred to.

Abstract: 769,389. Sewing machines. SINGER MANUFACTURING CO. May 23, 1955 [May 27, 1954], No. 14757/55. Class 112. In a zig-zag sewing-machine with an exchangeable pattern cam and a cam-follower lever with means for holding the latter in a desired position when the cam is removed as described in Specification 772,570, the shaft of the cam-follower lever is linked to the upper end of an arm 58 on a hollow shaft 60 and the needle-vibrating pitman 27 is connected to a cylindrical slide 66 in a corresponding guideway formed in a member 93 which is pivoted to the upper end of the arm 58 and is oscillated with the arm about the shaft 60 by the action of the cam, the amplitude of the vibration of the needle-bar being adjusted by shifting the slide 66 along the guideway by means of a link 73 from a handoperated lever. The member 93 is constrained to move with the arm 58 by a pin 80 carried eccentrically on a spindle 78 in the bore of the shaft 60, and is adjusted about its pivot on the arm 58, to adjust the "zero" position of the needle laterally, by turning the spindle 78 by means of a finger-knob on its other end; a collar 85 fixed on the shaft 60 has abutments 87 to determine the extreme positions of the member 93 by engagement with a spring plunger 83 in the latter and a central groove to be engaged by the plunger in the normal position of the member 93. In the form shown, in order to avoid lateral shift of the needle-bar by adjustment of the slide 66 along the guide, the slide engages a slot 96 in the end member 94 of the needle-vibrating pitman 27 and the oscillation of the member 93 is imparted to the pitman by a pin 98 on the latter engaging a curved groove 97 in the former, this groove being centred on the point of connection between the pitman and the needle-bar frame when the member 93 is in mid-position.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/24
Filed: 1951-06-22
Abstract: 683,596. Modifying surface reflection. RAULAND CORPORATION. June 22, 1951 [June 23, 1950], No. 14875/51. Class 97 (i). The low reflectivity cathode-ray tube windows described in Specifications 683,597 and 683,598, [Group XL (a)], are manufactured by blasting the outer or both surfaces thereof with a liquid suspension of a pulverulent abrasive material and then subjecting the window to the chemical action of hydrofluoric acid to smooth it to substantial light-transparency. The process may be carried out either before or after the window is sealed to the remainder of the envelope. The abrasive material may be finely divided silica particles having a particle size of 10-15 microns and is suspended in a solution of water and a detergent or melting agent and is directed at the window at a pressure of 80- 90 pounds per square inch. The blasting may be carried out in a scanning movement. The blasting is preferably for such a time that on treatment with hydrofluoric acid the reflectivity first falls and then rises again as shown by curve 10, but may be for a longer time to make the surface almost non-reflective so that the acid treatment starts at the minimum of the curve. The acid treatment in both cases ceases somewhere within region 11. The acid bath has a concentration of greater than 15 per cent at a temperature of 20-35‹ C., preferably 40 per cent at a temperature of 32‹ C. which takes about 20 seconds to etch a 7/ 32  inch thick glass plate for a metal cone cathode-ray tube; for glass bulb tubes the time is slightly longer. The protuberances on the surface of the finished window have a height of 5-20 microns and a diameter of 5-100 microns.

Title: Improved process for producing injectable insulin preparations with protracted effect
Inventor: HALLAS-MOLLER KNUD
IPC: A61K38/28
Filed: 1952-06-17
Abstract: An injectable insulin preparation of protracted effect consists of a suspension of amorphous insulin in an aqueous suspension medium, the suspension having a pH of 6 to 8.5 and a content of one or more of the metals zinc, cobalt, nickel, cadmium, copper, manganese and iron of above approximately 2 x A x 10-5 milliequivalents per millilitre, "A" denoting the number of international units of insulin per millilitre of the suspension, and the suspension being free of a content of such ions, which at neutral reaction have greater affinity to the mentioned metals than has insulin, so that less than 2 per cent of the insulin present in the suspension will be found in the dissolved state. The preferred content of the above metals is 3 x A x 10-5 to 18 x A x 10-5 and the preferred pH7.0.  Other materials which may be present are (a) buffers, e.g. acetate, borate, maleate, diethyl barbiturate and, in the case of nickel only, phosphate (b) isotonics, e.g. glucose, sodium chloride and glycerin, and (c) preservatives e.g. methyl-p-hydroxy benzoate, propyl p-hydroxy benzoate and phenyl mercuric acetate, in the form of solutions in alcohol.  The metals may be inorganic or organic salts such as chloride, sulphate, nitrate or acetate, or a hydroxide oxide or a complex metal compound.  The insulin is preferably in acid solution. If in crystalline state, it must be dissolved.  Amorphous insulin may be employed with such a content of the specified metals, that the content of the metal of the finished suspension is derived completely or partly from the amorphous insulin employed.  Such amorphous insulin has a metal content of over 0.4 milliequivalents per gram. Although the suspension may be prepared by mixing the starting materials in any sequence, it is preferred to mix an acid insulin solution with a solution of the other starting materials except the buffer, to filter through a bacteria proof filter, to add a sterilized solution of the buffer and to adjust the pH to 6-8.5, if necessary.
