Patent GB-1011228-A (GB)
Title: Method and apparatus for copying cinematographic films in colour or black-and-white
IPC: G03C7/22
Filed: 1962-07-17
Abstract: 1, 011, 228. Photographic copying apparatus. UNION TONFILMMASCHINENBAU G.m.b.H. July 17, 1962 [Aug. 11, 1961], No. 27368/62. Heading G2A. In copying cinematographic films in which alteration of light intensity on changing from one scene to another has not been corrected, this correction is carried out during the copying process by passing a control tape having apertures of different sizes in front of the light source abrupt changes of light flux being avoided by co-ordination of the tape and film advance. In the form shown, the negative and positive films run continuously over the track 2 of the copying frame 1, and past the copying slot 3 therein. Light from the lamp 4 passes through a condenser lens 5 and focusing lens 11, and is gathered by a light guide 12 which tapers to an edge corresponding to the slot 3. Between lenses 5 and 11 is a guide 9 having a light window 10. Through the guide can move the control tape 6 having apertures of different sizes, such as 7, 8, therein, which control the amount of light which passes. If it is desired to alter the amount of light, to compensate for a change in light value as one scene changes to another on the film, the tape is moved to bring a different aperture into window 10. The distance between successive apertures is so related to the size of the window that as one aperture moves out of the window area, another is moving into it, as in Fig. 2c (not shown). Thus there is never any complete interruption or abrupt change of the light intensity, which would show up undesirably as light flashes on the film. The invention may also be used with transparent tapes, in which the light control is effected by grey filters, and for colour control, in which subtractive colour filters are fitted over the grey filters.

Title: Improvements in rotary vane type compressors
IPC: F04C29/02
Filed: 1949-10-25
Abstract: 658,947. Rotary compressors and pumps. WAYMAN, C. P. Oct. 25, 1949, No. 27399. [Class 110(ii)] [Also in Group XIII] The sliding vanes 33 are forced outwards by oil under pressure of the delivery fluid. The latter acts on a blade 39, pivoted on a fulcrum 74, to press a sealing abutment 38 against the rotor 23 placed between inlet and outlet ports 18, 19. Delivery of compressed gas is made into a chamber 16 where oil is separated out by filter baffles 41, clean gas being exhausted through a pipe 42. The oil is returned to the vane slots by way of a pipe 49, valve 53 and ducts 34, 36 under delivery pressure, oil leaking from the slots lubricating the chamber bore and acting as a seal. To prevent flooding of the working chamber when the rotor stops, and a partial vacuum caused by suction ceases to act on a piston 71, a rod 72, moves upwards under pressure of a spring 73, and, through a pivoted lever 59 a rod 58 drops and allows the valve 53 to seat and shut off the oil supply. The piston 71 moves in a cylinder 63 provided with upper and lower ports 64, 65 controlled by the piston. Gas for the working chamber 11 follows the arrows shown in Fig. 3 and passes through ports 64, 65, cylinder 61 and inlet 18. As soon as the rotor stops the pressure on the piston 71 is balanced and the spring 73 forces it upwards causing the valve 53 to re-seat. Cooling water flows through .a jacket 13, provided with pipes 14, 15. A plate 31. closes off the filtering, chamber 16 from an oil chamber 35. The rotor is keyed to a shaft 28.

Abstract: 1281106 Change-speed gears ARDIE-WERK GmbH 8 June 1970 [13 June 1969] 27545/70 Heading F2D The ratio of a change-speed gear 6 is changed by sliding axially gears or dog clutches 18, 19 by an hydraulic jack 29, initiation of ratio change (e.g. by pressing a button 96 on an electric or electronic control 93 with a ratio indicator 94) causing disengagement of one ratio (and may be of the clutch 3 by an hydraulic jack 66) bringing the parts to be engaged into synchronism (e.g. by an hydraulic unit 58 either used as a motor under fluid supply from a pressurized reservoir 34 or as a pump in circuit with a relief valve 65, and detected by comparison of the outputs of tachogenerators 78, 79) when the ratio selected (e.g. by a button 95) is engaged by the jack 29, which acts quickly as it is fed and bled by a large flow electrohydraulic unit (e.g. a solenoid valve 52, 53 controlling a large flow poppet valve or spool valve 42, 43). Ratio change by the apparatus shown is stated to occur within a quarter second of pressing the button 96. The clutch jack 66 may have a similar electro-hydraulic unit-valves 69, 74-there being a one-way restrictor to slow clutch re-engagement after a ratio change. The valves 42, 43, 52, 53 may remain unpressurized until the button 96 is pressed when a valve 32 is actuated, may be after a switch 111 indicates that the clutch 3 is disengaged. The valves 32, 42, 43, 52, 53 and jacks 29 may be housed in a housing 7 on top of the gear-box 104. Figs. 2 to 4 (not shown) show the assembly of such a housing 7 with three jacks 29, another reservoir (34<SP>1</SP>) and without the valve 32.

Title: Operating mechanisms for electric circuit interrupters
IPC: H01H71/50
Filed: 1962-07-18
Abstract: 967,522. Automatic circuit-breakers; snap-action switches; heavy current switches. WESTINGHOUSE ELECTRIC CORPORATION. July 18, 1962 [Sept. 19, 1961], No. 27598/62. Heading H2B. In a switch such as a gas-filled automatic line sectionalizer, snapaction is provided by a flexible lever or lever system having one end pivoted and its free end connected to a movable contact 62 and co-operating with latch means such that rotation of the free end with respect to the pivot is prevented until the lever or lever system has been flexed to store energy and to reduce the distance between the free end and pivot so that the free end is released from the latch. In Figs. 6 and 7 a lever 34 is pivoted to a frame at 37 and to a lever 35 at 47. A spring 61 is compressed between levers 50, 52 pivoted at 47 and having bars 48, 49 extending on the top and bottom of both levers 34, 35. To open the switch from the position shown in Fig. 6, an operating handle (not shown) is turned about a fixed pivot to move an operating rod 141 downwardly. This causes the levers 34, 35 to buckle into the position of Fig. 7 until the free end of the lever 35 slips past the latch 110, whereupon the spring 61 turns the lever 35 into alignment with the lever 34, so opening the contacts 62, the lever being arrested by a buffer 155 and passing beyond a second latch 84. To reclose the switch the rod 141 is moved upwardly to cause the reverse action to take place. When the switch functions as an automatic line sectionalizer, the counting device of Specification 967,523 moves a trip bar 173, Fig. 8, to move a latch member 179 away from the stem 122 of the latch 110 so that the latch is able to pivot about lugs 129 and release the lever 35. The levers 34, 35 turn together under the action of gravity or biasing springs (not shown) to open the contacts without snapaction. The trip bar 173 also turns a lever 202 away from the pivot 37 so that should the operating rod 141 be held in the closed position when the switch operates automatically, the levers can pivot about the pivot 143 to open the contacts. In Fig. 9, the flexible lever is a leaf-spring 211 which is pivoted at 212 and has its free end connected to the movable contact 217. The free end co-operates with latches 213, 214 and a stop 215. The operating member 216 is connected to the leaf-spring near the pivot 212.

Title: Process for catalytic hydrodesulfurization of petroleum hydrocarbons and catalysts therefor
IPC: B01J23/86
Filed: 1957-09-03
Abstract: A hydrodesulphurization catalyst supported on a porous carrier, e.g. alumina, contains molybdenum, preferably 4-16% (wt.) and at least two of the metals iron, nickel and cobalt as their oxides, sulphides or combinations of oxides or sulphides with molybdenum oxide or sulphide, the atomic ratios of each metal to molybdenum being less than 0.4 and the sum of the atomic ratios of the metals to molybdenum being less than 0.8.  One member of the metals can be present in a substantially smaller atomic ratio to molybdenum than the other, for example, in a catalyst containing molybdenum with cobalt and nickel, the cobalt to molybdenum ratio is 0.01 to 0.05 and the nickel to molybdenum range is 0.1 to 0.2 The catalysts are used to reduce the sulphur content of sulphur containing hydrocarbons, for example, furnace oils, naphthas, cracking charge stock, shale oils, coke oven oils or residual-containing hydrocarbons, such as whole crude or reduced crude, by contacting the hydrocarbon with hydrogen in the presence of the catalyst at a temperature between 260 DEG  and 480 DEG  C. Suitable carriers for the catalyst are alumina, alumina stabilized with 2% to 10% silica, bauxite, and silicaalumina cracking catalysts.  In a preferred method of preparing the catalyst, the carrier is impregnated first with the molybdenum component, for example, ammonium molybdate, molybdenum oxalate or molybdenum pentachloride, from an aqueous solution followed by calcining and secondly with the metals, preferably in the form of their nitrates or acetates followed by calcining.  The catalyst can be regenerated by contacting with oxygen-containing gas, such as air at elevated temperatures, preferably, above 540 DEG  C.
