Title: Improvements in or relating to processes for gravimetric separation of granular and/or pulverulent materials
IPC: B03B5/24
Filed: 1967-03-24
Abstract: 1,185,221. Separating granular materials. BUREAU DE RECHERCHES GEOLOGIOUES ET MINIERES. 24 March, 1967 [26 March, 1966], No. 8898/67. Heading B2H. A jig for separating material, e.g. an ore, into fractions of different specific gravities comprises a filter bed or a porous separation surface 12 forming the bottom of a container which is bounded on opposite sides by a feed channel 13 and a vertically adjustable plate 22 constituting a discharge weir for the light fraction and which is clamped on to a tank 6 containing fluid 17 to which pulsations are imparted by means of a flexible membrane 2 which is mounted on the tank 6 and is vertically reciprocated through linkages by means of a motor 5. The flow of the material over the bed or surface 12 is regulated by means of a vertically adjustable baffle plate 14. The dense fraction of material is retained on the bed or surface 12 at 20, 21 by means of one or more cross-bars 15 and by the plate 22 respectively. The fine material in the dense fraction passes through the bed or surface 12 and may be collected by means of a trap arranged at the bottom of the tank 6. The surface 12 may be formed by a sintered bronze plate or of a porous sheet of plastics material supported by a grid .The jig may be of the wet type, the liquid used being water or, to promote separation, a liquor of high density, e.g. one containing tetrabromoethane. Alternatively, the jig may be of the dry type with air as the pulsating fluid, in which case the bed or surface is given a slope. The operation may be discontinuous and the removal of the dense materials at 20, 21 in this case may be effected manually. Alternatively, the operation may be continuous. In the latter case, fragments or calibrated blocks of the material being separated, or of a material of the same density, are supported by a grid to form a filter bed.

Title: Improved current rectifying tube
IPC: H01J17/04
Filed: 1946-03-22
Abstract: 623,012. Metal-vapour converters. PHILIPS LAMPS, Ltd. March 22, 1946, No. 8924. Convention date, Oct. 17, 1941. [Class 39 (i)] In a rectifier having a gas pressure of greater than 0.3 mms. of mercury and designed to operate with an anode voltage greater than 100 and a current greater than 10 amperes, the anode or anodes and the cathode are protected by separate screens in combination with a labyrinth such that back-fires do not occur. As a criterion of this latter condition the tube may be operated at full working load with a cathode voltage of half the normal; if no back-fires occur, the screening is adequate. The anode screen has a part which fully screens the anode load and a conductive part which screens the inactive surface of the anode. The Figure shows a mercury-vapour rectifier according to the invention. The cathode 32 is surrounded by a screen 44, which may be connected to a suitable potential; the front of the screen 47 may have starting-up apertures 49. This screen also forms the labyrinth. The tube is filled with argon at 0.7 mm. pressure, and also contains liquid mercury 50. Specifications 345,080, 429,075, 444,424 and 553,012 are referred to.

Title: Improvements in or relating to hydraulic servo-assisted steering-gears for automobiles
IPC: B62D5/24
Filed: 1957-03-22
Abstract: 833,778. Vehicle power steering. REGIE RATIONALE DES USINES RENAULT. March 22, 1957 [March 27, 1956], No. 9477/57. Class 79(5) A hydraulic circuit for the steering gear of a motor vehicle comprises a reservoir 16, a pump 14, a steering linkage actuating cylinder 38, and a pilot valve 44 controlling the flow to the cylinder 38 in response to a pressure differential created between two lines 25, 26 by a control valve 53 responsive to the driver's steering effort. The steering column 1 is connected to the drop arm 10 through a flexible coupling, a sleeve 2, a worm gear 8, 9 and a shaft 5 which is connected to the sleeve by longitudinal splines 6 and to the worm by helical splines 7. Rotation of the column 1 causes axial movement of the valve 53 and progressive closure of one or the other of two sets of parts 32, 33 so that the flow from the pump 14 is unequally divided between gauged jets 21, 22 leading to the pipes 25, 26, the unequal pressures on the valve 53 providing "feel". Ducts 49, 50 on the downstream side of the jets cause the resulting pressure difference between the pipes to move the valve 44 to close one or other of the jets 21, 22. Fluid is thus supplied to one side of the cylinder 38 while the other side is connected to exhaust through the inner space 34 of the steering box and a pipe line 19. In the event of a pressure failure, manual steering may be effected once the movemnt of the valve 53 has been taken up, the cylinder 38 having its appropriate side connected to exhaust by one of a pair of valves 58 which is opened against spring pressure by the pressure reduction caused by the initial movement of the steering linkage and the piston 42.

Title: Improvements in or relating to flexible joints for electric cables
IPC: H02G15/24
Filed: 1960-03-18
Abstract: 902,431. Insulating cable joints. PIRELLI S.p.A. March 18, 1960 [April 30, 1959], No. 9637/60. Class 38 (1). Preparatory to jointing two oil - filled leadsheathed cables, rings 2 of elastic material, e.g. synthetic rubber, are inserted between the lead sheath 1 and insulation 3 to reduce leakage of oil during the jointing operation. Rings 4 located in grooves 6 also act as seals between the sheath 1 and a lead sleeve 9. The cable conductors are connected by a ferrule 5 which, after fitting, has a diameter precisely equal to the diameter of the conductors. The insulation 3 is then stepped back before building up insulation 3<SP>1</SP> by impregnated paper tapes, the direction of winding of alternate layers being of opposite hands. After applying an electrostatic screen formed of carbon paper or metallised paper, impregnated paper tape is applied to form a filling 7 over which are wound two thick paper tapes to protect the screen during the operation of reducing the diameter of the sleeve 9. After soldering the ends of the sleeve to the sheaths of the cables being joined, a rigid metal tube 15 (not shown) split longitudinally in halves is secured around the sleeve 9 to prevent distortion of the latter during evacuation and impregnation of the joint. The tube is then removed and the sleeve reduced in diameter so that it presses against the rings 4. The ends of the sleeve beyond the rings are then removed and the new ends sealed to the sheaths 1 with lead, Fig. 4. The joint is completed by soldering lead bands 11 at either end.
