Title: Electrical method for protecting metal surfaces from corrosion and formation of incrustations
IPC: C23F13/02
Filed: 1949-02-22
Abstract: 657,392. Preventing corrosion. HAJOSI, C. A. Feb. 22, 1949, No. 4786. Convention date, Feb. 17, 1949. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 25, 1949]. Drawings to Specification. [Class 123(i)] An electric method of preventing and removing scale comprises applying a periodically varying potential across the wall of the vessel to be protected and an element, e.g. an insulated electrode, in electrical contact with the liquid in the vessel. During the intervals separating two peak values the potential is lower than the counter e.m.f. of the cell (formed by the vessel, the liquid, and the electrode), and the wall of the vessel is always negative with respect to the electrode,' except when the potential difference equals zero. Three circuits are described as suitable for producing appropriate wave forms, viz:- (a) a rectifier circuit, (b) a relaxation oscillator using a neon tube, and (c) a frequency modulation circuit, the potential to the vessel and electrode being taken out of the anode circuit of the valve. In this third circuit the frequency of the pulses varies cyclically, it being constant in the other two. In the last two cases the pulsating voltage may be superimposed on a steady voltage, and should always preferably be rich in harmonics.

Title: Presses for compressing liquid containing material into block form
IPC: B30B9/06
Filed: 1977-02-04
Abstract: 1535356 Platen press filter W GREEN SON & WAITE Ltd 4 Feb 1977 [6 Feb 1976] 4828/76 Heading B1D [Also in Divisions B4 and B5] Blocks are moulded from a water containing material, such as partially dried pulp, by feeding a charge of the material from a hopper 11 to a press 10 by a gauge box 14 horizontally reciprocable by means of an hydraulic ram 15 from a position under the hopper to a position between the platens 19, 21 of the press. In the latter position, the hopper outlet is closed by a plate 17 carried by the box and the box is located over an enclosure 26 the base of which is formed by the lower platen 19. The material is deposited in the enclosure and the upper platen lowered by main and auxilliary rams 22, 23 to effect compression, the water from the material being withdrawn by suction or pressure through apertures in the platens. After pressing, the upper platen is raised, the box returned to its position under the hopper to be refilled, and the lower platen raised clear of the enclosure so that upon the next feeding stroke of the box the compressed block is pushed onto a lowerable stacking platform 42. Compressed air may be fed to the apertures of the platens to help release the block and to clear fibrous material from the apertures on the screen overlying the apertures.

Abstract: 575,405. Dividing by fusion. PITT, M. March 16, 1944, No. 4938. [Class 83 (iv)] An oxygen gas-cutting apparatus comprises a carriage mounted on wheels at its front and rear ends, a torch, a motor and gearing for driving the carriage carried by the front end of the carriage, a control valve carried by the rear end of the carriage and pipes by which oxygen and gas are conducted from the control valve to the torch and also by which the oxygen is conducted to the motor, a number of pipes forming the sole rigid connection between the front and rear ends of the carriage. The torch i may be adjustably secured in a clamp h laterally adjustable in a support in the front portion of a carriage provided with a pair of wheels a on an axle b driven through worm gear f, f and reducing gear g ... g<5> from a motor c. The rigid gas and oxygen tubes n, o connect the front to the rear of the carriage, the latter consisting of a valve box j mounted on a castor wheel k, and provided with gas &c. controls p<1>. The motor is driven by oxygen supplied thereto from a flexible tube e through a speed regulating valve d. If desired, this oxygen may after driving the motor be utilized in the torch. One or more trailing wheels q may be used to support the front end of the carriage when cutting to the end of the work. After the motor has been started, the supply of oxygen thereto may be cut off and the apparatus propelled by hand. The motor may be connected to the gearing by a clutch which is released when the carriage is to be propelled by hand, the gearing providing sufficient resistance to prevent a quick travel of the carriage.

Title: Improvements in or relating to a method of isolating protein from oil seeds
Inventor: URE GEORGE REID
Filed: 1953-02-23
Abstract: A metod of isolating blanched protein from de-oiled seed-meal, e.g. ground nut meal, comprises treating it with an aqueous solution of an aldehyde, e.g. formaldehyde, paraldehyde, prior to the extraction of the protein with alkali, and recovering the protein by adjusting the pH of the clarified solution, e.g. with hydrogen chloride, sulphur dioxide, sulphuric acid, to the iso-electric point of the protein, e.g. pH 4.0 to 7.0.  The treatment with formaldehyde is carried out in a neutral or alkaline aqueous medium containing up to 1 per cent by weight of formaldehyde, the formaldehyde being subsequently eliminated by ammonia, urea, hydroxylamine, hydrogen peroxide prior to the extraction of the protein.  The treatment with other aldehydes is preferably carried out in an acidic aqueous medium.

Title: Improvements in the manufacture of mortars and concrete and in building insulating and other materials prepared therefrom
IPC: C04B24/36
Filed: 1944-03-18
Abstract: Mineral oil refinery sludges are extracted with alcohol, which may contain a proportion of a solvent for unsulphonated hydrocarbons such as 5-10 per cent of benzene, and the extract is added to concretes or mortars to increase their workability or to reduce the quantity of water necessary for mixing.  The extract contains sulphonic acids or sulphonates and unsulphonated substances which form colloidal solutions in solutions of sulphonic acids.  Methylated spirit to which may be added 5-10 per cent of benzene is agitated for 1/2 -3 hours with 50-100 per cent by volume of sludge and allowed to stand. The solvent layer is decanted and evaporated.  The residue is added in the proportion of 0.1-2 per cent of the binding agent, either dry or with the gauging water.  Owing to the increased plasticity of concretes containing this extract, such are very suitable for spraying and extruding processes.  The set concrete is close textured and water repellant.  This latter property can be increased by the addition of oils, waxes, fatty acids, or the like.
