IPC: B24C1/00
Filed: 1960-01-27
Abstract: 898,172. Blasting. TURNER, H. C. Jan. 23, 1961 [Jan. 27, 1960], No. 2912/60. Class 60. A method of treating leather or synthetic plastic articles, such as shoes, wearing apparel, handbags and cases, comprises subjecting the surface to be treated to a stream of fluid containing hard particulate material, the fluid being in a cooled condition so that frictional heating of the treated surface is minimised. The leather or plastic material is cleaned by the method without affecting its nature, suede or like materials retaining their nap. Leather is decolourised by the method without closing the pores so that it can be re-dyed. The hard particulate material may be oat husks, cocoanut shell, crushed iron shot, aluminium oxide, carborundum, corundum, glass beads or granite chips or mixtures thereof. The fluid may be gaseous air, nitrogen or carbon dioxide. The cooled condition of the fluid may result from a change of state, e.g. if carbon dioxide is used it is obtained from a cylinder in which it is stored in liquid form under pressure. A blasting gun is used, the diameter of the nozzle orifice being between 0.0075 inch and 0.50 inch The pressure of the particle-laden fluid stream issuing from the nozzle ranges from 0.5 p.s.i. to 300 p.s.i. The particles are from 0.002 inch to 0.060 inch diameter. The treatment may be in two stages, cleaning being followed by finishing.

Title: Improvements in or relating to radar system
IPC: G01S7/20
Filed: 1952-02-05
Abstract: 729,442. Pulse radar. GILFILLAN BROS., Inc. Feb. 5, 1952 [Feb. 17, 1951], No. 3007/52. Drawings to Specification. Class 40 (7). A circuit which generates range-marker pulses for application to a cathode-ray display unit in a pulse-radar system is triggered by pulses which are derived from the trailing edges of the output from an adjustable-delay flip-flop which is itself triggered by pulses derived from the transmitter-synchronizing-pulse generator. The circuit finds particular application in a groundcontrolled-approach (G.C.A.) radar system in which the marker pulses are required to commence from an arbitrary position on the display corresponding to the desired point of touchdown. The transmitter trigger pulses are applied to a flip-flop circuit producing output pulses whose length is adjustable between 0 and 75 microseconds. These pulses are applied to a differentiating circuit and the pulses corresponding to the trailing edge of the flip-flop output are applied to a further flip-flop which generates pulses of 100 microseconds duration. These pulses are applied to a normally-conducting valve which is connected in shunt with the oscillatory circuit of a Hartley oscillator which is consequently normally rendered inoperative. Upon the application of the 100-microsecond pulses thereto the valve is cut off, thus allowing the oscillator to generate oscillations which are applied through peaking stages to a blocking oscillator wherein the range-markers are generated in synchronism with the oscillator output.

Title: Dehydration of solutions and dispersions of solid organic substances in water
IPC: B01D1/12
Filed: 1964-01-24
Abstract: Liquids such as plum juice, apple juice, tomato juice, beer, cider or wine are concentrated by causing the liquid to flow in contact with one side of a water-permeable layer formed in situ by accumulation of solid, organic, hydrophilic material, while the pressure on the other side of the layer is maintained such that water evaporates therefrom. The formation of the layer is brought about by causing a liquid in which the solid, hydrophilic material is present to flow in contact with a thin perforated sheet made of stainless steel wire gauze, sintered metal or glass, silk, cellulose, or cellulose acetate, while quickly withdrawing vapour from the surface of the liquid.  In some cases, the layer-forming layer may be same as the liquid-to-be-concentrated. As shown, water-permeable layers are formed on stainless steel gauzes, stretched in five parallel pairs so as to form five diffusion cells 13.  Steel spirals 15 are provided between the gauzes of each pair to maintain them 1.5 mm. apart.  The liquid to be concentrated flows between the gauzes; and air, preheated by heater 12, is forced over the cell by fan 9. Water-vapour is taken up by the air; and some of the air is circulated by fan 10 through condenser 11, where water is removed from the system.  In a modified apparatus, the evaporation is carried out in a vacuum by positioning a condenser close to the water-permeable layer.  A flat heater is placed on the opposite side of the layer. <PICT:1037132/C6-C7/1>

Title: Improvements in and relating to hydraulically operated injection moulding presses
IPC: B29C45/82
Filed: 1947-02-05
Abstract: 652,360. Injection moulding machines. VLTAVSKY, V. Feb. 5, 1947, No. 3465. Convention date, Dec. 30, 1941. [Class 87 (ii)] [Also in Group XXIX] In an hydraulically-operated injection moulding press in which the pressing together of the mould parts 4, 5, the motion of an injection chamber 10 and its associated plunger 14 towards the mould, and the injection stroke of the plunger in the chamber are all effected by hydraulic pressure, and wherein the motion of the chamber is produced by pressure-applying pistons 7, 7a operating in fixed cylinders 3, 3a, the injection chamber and an injection cylinder 12 in which a piston 13 which carries the plunger 14 works, form an integral union with piston rods fixed to the pressure-applying pistons. As shown, a pump 15 supplies pressure to a mould closing cylinder 2, an accumulator 33, the cylinder 12 and the cylinders 3, 3a. The pistons 7, 7a have lower piston rods 8, 8a and higher piston rods 11, 11a which respectively support the chamber 10 and the cylinder 12. Valves 19, 21 are actuated simultaneously as also are valves 22, 24 so that the one is opened as the other is closed. The pump 15 forces liquid through a pipe 23 into the cylinder 2, through a pipe 20 to the cylinders 3, 3a and by means of a pipe 40 to the cylinder 12. The accumulator 33 is connected to the space 31 behind the piston of the cylinder 2, to the cylinders 3, 3a and by means of the pipe 40 to the cylinder 12. The accumulator is fed from the pressure space 28 of the cylinder 2 by opening a valve 38. To operate the press, the valve 19 is opened and the valve 22 is closed so that the space 28 in the cylinder 2 is not under pressure. The accumulator pressure forces the piston 6 to the left but is not sufficient to overcome the pressure in the space 30 and the lower spaces of the cylinder 3, 3a. The valve 24 is then closed and the valve 22 opened and pressure is forced into the space 28 and the piston 6 is thus urged to the right closing the mould 4, 5. The valve 19 is closed and the valve 21 opened thus relieving the lower spaces of the cylinders 3, 3<SP>1</SP> and 12 of pressure, whereby the pistons 7, 7a and 13 are forced downwards by the accumulator pressure and injection takes place.

Title: Conversion of hydrocarbons
IPC: C10G11/18
Filed: 1955-02-08
Abstract: A catalytic cracking process comprises cracking a virgin hydrocarbon oil feed in the presence of a cracking cataylst under conditions such that less than 50 per cent by weight of the feed is cracked on a once through basis, fractionating the vaporous cracked products to obtain a cycle oil whose boiling range lies within the 10 and 80 per cent distillation points of the virgin feed and recycling the cycle oil to the cracking step, the amount of cycle oil recycled being between: <FORM:0765004/III/1> and <FORM:0765004/III/2> where A represents the weight per cent of carbon in the aromatic hydrocarbons in the virgin hydrocarbon oil feed and where B represents the volume per cent of the virgin hydrocarbon oil feed which boils within the boiling range of the cycle oil being recycled.  The catalyst is preferably a silica alumina catalyst but silicamagnesia or acid treated bentonite clays may be used. The particles may be between 20 and 100 microns, and the fixed bed or moving bed processes may be used.  In an example a mixed sweet gas oil having a boiling point of 600-1050 DEG F. was treated to give a product containing about 60 per cent of motor gasoline.

Title: Improvements in or relating to booster-operated hydraulic braking systems
IPC: B60T13/24
Filed: 1944-02-28
Abstract: 589,075. Brakes. BENDIX AVIATION CORPORATION. Feb. 28, 1944, No. 3685. Convention date, March 1, 1943. [Class 103 (i)] [Also in Group XXVI] In a braking system which is controlled by a pedal operated master-cylinder, the valve controlling the differential air pressure in the booster is itself controlled both by the opposed hydraulic pressures in the master cylinder and the booster-operated secondary master cylinder, and by the differential air pressure in the booster. As shown, pressure from the pedal operated master cylinder 12 is transmitted through the pipe 13 and ball valve 71 to the tube 73 and from there to the brake cylinders 14a. Brake slack is thus taken up quickly by the direct action of the pedal 11, after 'which the pedal-produced pressure causes the plunger 70 to slide against the spring 76, and close the vacuum-opening 58 in a flexible diaphragm 43. Further pressure on the pedal causes the diaphragm 43 to move against the spring 77 and open the air-valve 47, permitting the admission of air through the filter 45 and ports 57 in the plunger 70 to the back of the piston 24, both sides of which are normally subject to vacuum. When the air pressure rises and operates the piston 24 to boost the pressure in the auxiliary mastercylinder 27, to an extent corresponding to the degree of pedal operation, the diaphragm 43 is moved by the air pressure to close the air valve. Also the plunger 70 is maintained in equilibrium by the opposed forces of the pedal produced pressure, the pressure of the spring 76 and the power-produced hydraulic pressure acting on the step or shoulder of the plunger. A pin 66 keeps the check valve 71 open until the movement of the plunger 70 closes the vacuum valve. The seals between the cover 40 and the air valve 47, and between the valve and the plunger 70, consist of soft leathers 48, 54 secured in position by cupped spring washers 49, 55. Plugged opening 34 serves as a bleeder connection and a plugged opening 68 also serves as a bleeder connection, or it may be used as a brake line connection or to operate other controls. The vacuum cylinder 10 is closed by a cover 28 secured by screws 29 threaded into anchors 30 spot-welded or otherwise secured to the inside of the cylinder The cylinders 10 and 27 may be secured inside the shell, the unoccupied spaces in the shell being used as a vacuum or pressure reservoir. In a modification, the housing 60 for the plunger has a straight bore instead of a stepped bore, a floating cap being provided inside the bore to present a shoulder to the cup leather 62. The plunger 26 is not internally bored to transmit the pedal-produced pressure to the cylinder 27, but this pressure is transmitted by an external pipe leading from the opening 68. Compressed air may be used for the power application instead of vacuum, and the ball valve 71 may be replaced by any form of check valve.
