Filed: 1962-04-18
Abstract: 935,145. Hydrostatic transmissions. KOPAT GES. FUR KONSTRUKTION, ENTWICKLUNG UND PATENTVERWERTUNG. April 18, 1962 [April 20, 1961], No. 15145/62. Class 69 (2). In a hydrostatic transmission having make-up and lubricating liquid supplied thereto by a pump 11, a valve 17 in a by-pass line between the pressure and return lines of the transmission, and a valve 25 controlling two lubricating oil paths, are both controlled by the pressure in the make-up and lubricating supply line 15. The transmission comprises an axial piston pump having a driving cylinder barrel 2 and an adjustable swash-plate 6 pivotally mounted on a driven housing 8, and driving an axial-piston motor having a stationary cylinder barrel 3 and a swash-plate 7 pivotally mounted on the driven housing 8. A valve disc 10 between the pump and motor is fast with the housing, which carries an output pinion 9. In the right-hand position of a control valve 20 the pressure in the line 15 is maintained at a low value by an adjustable relief valve 23, the valve 17 is held in its right-hand position by a spring 16 so that the pressure and return lines of the transmission are interconnected, and the valve 25 is held in its right-hand position by a spring 24 so that liquid from the line 15 is supplied through the valve 25, a chamber 27, ducts 28, 29, a chamber 30 and a throttling orifice 31 to lubricate bearings 32, 33 of the pump. When the valve 20 is actuated to shut off flow through the relief valve 23, the pressure in line 15 rises until the valve 17 is actuated to close the by-pass so that the transmission transmits torque, and valve 25 is actuated to open the supply line 15 through ports 34 to a chamber 35, duet 36 and chamber 37 and outlet ports 38, 39 to lubricate and cool all the transmission bearings.

Title: Improvements in or relating to apparatus for weighing out liquids
IPC: G01G13/00
Filed: 1939-05-22
Abstract: 529,641. Weighing-apparatus. CREIGHTON, C. R., and WATERS, D. B. May 22, 1939, No. 15228. [Class 143] Relates to apparatus for delivering weighed quantities of viscous liquids, of the kind wherein a filled weigh hopper with a valve-controlled outlet is caused, by a reduction of the balancing means, to discharge liquid until the reduced balancing means moves the weigh hopper and closes the outlet. According to the invention in order to avoid errors due to the viscosity of the liquid the same balancing conditions under which the weigh hopper reaches equilibrium during filling and after discharge are obtained by closing the outlet in each case whilst liquid is passing through. As shown, the weigh hopper 6 is in balance with a small residual quantity of liquid therein, the outlet valve 8, carried by fixed arms 9, 10, being closed and the scale pan 4 being empty. A weight 5 equal to the liquid charge required is placed on the scale pan and liquid run in, for example, through a cock 12. When the liquid overbalances the weight 5 and runs past the valve the cock is closed, the liquid running to waste until the weigh hopper rises and closes the valve. The weight 5 is now removed and the liquid run out until the hopper rises sufficiently to close the outlet. Means may be provided for performing the operations automatically.

Title: Improvements relating to the removal of vanadium and/or sodium from petroleum and hydrocarbons of petroleum origin
IPC: C10G45/06
Filed: 1952-06-18
Abstract: Crude petroleum or hydrocarbons of petroleum origin containing vanadium and/or sodium are refined by contacting with a material consisting essentially of iron oxide and alumina, in the presence of hydrogen, under such conditions of temperature and pressure that the vanadium and/or sodium is deposited on the material.  The preferred refining conditions are a temperature of 750-800 DEG  F., a pressure of 500-1500 p.s.i.ga., a space velocity of 0.5-2.0 v./v./hr. and a hydrogen recycle rate of 1000-10,000 S.C.F./B. The refined product may be passed to a catalytic hydrogenation process for the removal of organically combined sulphur.  Thus, crude petroleum or a petroleum residue may be refined according to the process of the invention and then hydrofined using a catalyst consisting of cobalt and molybdenum oxides supported on alumina.  In an example, a petroleum residue is refined by contact with iron oxide on alumina (12.8 per cent wt. Fe2O3) in the presence of hydrogen, the refined product having reduced sodium, vanadium and sulphur content.  Specification 729,301 is referred to.

Title: Improvements in and relating to milking machines
IPC: A01J5/04
Filed: 1925-06-12
Abstract: 237,879. Melotte, A. July 29, 1924, [Convention date]. Cow-milkers. - Tn milking-machines wherein the vessel receiving the milk is filled by the action of suction upon the udder of the animal, in order to stop the operation when the vessel is full the suction duct is provided with a valve so that as soon as the milk reaches a predetermined level the suction is cut off by the valve. As shown, a ball valve 6 is arranged in the suction duct 2 leading from the vessel 1, a channel 3 being connected to the udder of the animal. Normally the ball rests over a lower orifice 7, but during milking the ball is raised slightly and the suction transmitted to the udder. After, however, the level of the milk in the vessel has risen to that of the ball, the ball is raised until finally it closes the orifice 5 and so cuts off the suction from the vessel and the udder. A pulsator is connected to a bye-pass 4 of the duct 2, and a stop-cock 8 provides hand control of the flow of milk into the vessel. The Specification as open to inspection under Sect. 91 (3) (a) states also that the valve may be arranged at a distance from the vessel and be controlled by a float connected to it. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,141,636. Photographic type-composing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 April, 1966 [9 April, 1965 ; 22 May, 1965], No. 15332/66. Heading B6W. [Also in Division H4] The invention relates to the selection of an individual symbol from a symbol carrier e.g. a photographic film, and the reproduction of the selected symbol on a selected area of a sensitive film, a phosphorus screen or a projection screen. As shown, Fig. 2, a collimated laser light beam L is deflected by means of a digitallycontrolled deflection device A 1  and the deflected beam is focused by a lens O 1  on to the symbol carrier F which is positioned adjacent the focal plane of lens 0 1 . The beam emerging from the selected symbol is collimated by a lens O 2  and its deflection from being parallel to the optical axis of the system is neutralized by a second digitally-controlled deflection-device A 2 . A third digitally-controlled deflection device A 3  deflects the beam so that an image of the selected symbol is produced on a selected area of the focal plane D of a lens O 3 . Each digitally-controlled deflection device comprises a plurality of bi-refrigerant prisms (43) and polarization Kerr cell switch (42) combinations, Fig. 1 (not shown), as described in Specification 994,955. An inversion mirror or prism (R) may be arranged behind the lens (O 2 , Fig. 3, not shown) so that the laser beam passes back through the deflection device (A 4 ) and is deflected by a dividing mirror (S) into the "third" digitally-controlled deflection device. A further arrangement which permits the preselector of the individual symbols to be used twice utilizes a lens (L 3  or L 2 . Figs. 4 and 5, not shown), and a plane mirror (S 2 ) in the focal plane of the lens. The symbols may be reproduced on a projected background e.g. a map, Fig. 6 (not shown), and to improve colour contrast the areas of the projected background T 1  where the time-variable symbols appear on the projection plane P<SP>1</SP>, Fig. 7, may be blanked out by means of a layer T 2  of photochromic absorbent material on to which the corresponding symbols are projected by means of an auxiliary apparatus comprising digital lightdeflection devices 33 and 17<SP>1</SP>, a symbols mask 12<SP>1</SP> the same as the main symbol mask 12 and an optical system 13<SP>1</SP>, 14<SP>1</SP> and 15<SP>1</SP>. The deflection devices 16, 17, 17<SP>1</SP> and 33 and amplitude modulators 2 and 31 being controlled by a signal generator 6.
