Title: Improvements in or relating to change speed gears
IPC: B60K26/00
Filed: 1930-03-31
Abstract: 347,437. Variable speed gearing. CARLING, W. T., Tangley, Sydney Road, Guildford, Surrey. March 31, 1930, No. 10134. [Class 80 (ii).] Relates to devices of the kind in which (a) the clutches or gears of variable-speed gearing are normally locked against inopportune engagement, (b) a resilient clutch stop, for example as described in Specification 298,313, [Class 80 (ii), Gearing, Variablespeed &c.], is controlled by means, such as described in Specification 332,706, [Class 80 (ii), Gearing, Variable-speed &c.], to allow alternatively slight engagement of the stop or such engagement as will eventually turn the driving-shaft of the speed gear backwards to unlock the gearing, (c) fuel is reduced or ignition prevented during speed change by means comprising a switch which is closed by movement of the gear lever. The invention consists in the provision of an additional switch which is automatically operated to cut out the fuel or ignition control, so that a car can be started from rest without stopping the engine. As shown, the full motion of the clutch lever 7 through the plane of the paper is prevented by a pivoted lever 5 maintained in position by a spring b, in which condition the driving- shaft of the speed gear is slowed by limited engagement of the clutch stop so as to facilitate speed changing. The lever 5 is connected to a rod 4 to a switch la, 2a arranged in a circuit containing a battery 12, a magnet 11 adapted to reduce the fuel supply, and a switch 9 which is closed by operation of the gear lever, for example as described in Specifications 315,967 and 316,790, [both in Class 80 (ii), Gearing, Variable-speed &c.], so that with the lever 5 in the position shown, the fuel-reducing means is operative when the gear is changed. When the lever 5 is moved from the path of the lever 7, the switch la, 2a is opened so that the magnet 11 is inoperative and the lever 7 may be fully depressed so to engage the clutch stop as to effect reversal of the gear-driving shaft and unlocking of the clutches or gears of the variable-speed gear, when the first gear can be engaged without the engine power being affected. In alternative arrangements, the circuit may be arranged normally to earth the magnets during gear-change, or to break the circuit of ignition coil, in which case the additional switch 1a, 2a is arranged in parallel with the switch 9, so as to short-circuit it. Two additional switches may be employed, one for the fuel control and the other for the spark control.

Filed: 1941-09-08
Abstract: 582,202. Panoramic receivers. DODDS, J. M., WHALLEY, H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 8, 1941, No. 10143. [Class 40 (v)] In a panoramic receiver, means are provided for automatically suppressing the cathode-ray beam during the return sweep to avoid confusion, the means comprising a switch 9, operated by a cam 8, on the shaft 7 of the motor-driven scanning condenser so as to apply a square voltage wave going alternatively positive and negative with respect to the mean potential of the grid 3. The potential is obtained from a potentiometer 12, 13 and applied through a condenser 17, a radiofrequency byepass condenser 14 being provided. With shaft 7 stationary and switch 9 open the grid 3 assumes a negative bias due to resistance 16. This gives a reduced brilliance of the trace for manual tuning. Specifications 582,201, [Group XXXVI], and 582,203 are referred to.
Patent GB-687243-A (GB)
Title: Process for the catalytic oxidation of olefins
Filed: 1951-05-01
Abstract: Olefine oxides are produced from gases containing olefin and hydrogen by preliminarily selectively oxidizing the hydrogen at a temperature below the oxidation temperature of the olefin, and then selectively reacting the olefin in low concentration with oxygen at 220-350 DEG C., and superatmospheric pressure, generally 5-25 atm., in the presence of a silver catalyst.  Unsaturated hydrocarbons, particularly acetylene, if present, may be oxidized in the preliminary step.  If acetylene or diolefins are present in high concentration, a mild hydrogenation may precede the initial oxidation.  Unreacted gases from the olefin oxidation may be recycled to the feed-stock to act as diluents and to provide oxygen for the preliminary oxidation.  Purge gases may be treated to oxidize residual olefins.  The feed to the olefin oxidation stage may contain 1-6 per cent ethylene, and 5-10 per cent oxygen.  The catalyst is preferably silver or silver oxide on a spherical support having surface irregularities as described in Specification 674,412.  The preliminary oxidation may be effected with a supported copper catalyst, with or without chromium, or with a silver catalyst at below 220 DEG  C.  The initial hydrogenation may be effected with iron, nickel or palladium.  Inhibitors such as chlorine or other halogens, ammonium, hydrogen, ethylene or vinyl chloride, in amounts of 0.001-0.10 per cent, may be added to the feed to the olefin oxidation zone.  The olefin oxide may be scrubbed out with water under pressure.  The initial olefinic gases may be obtained from cracking petroleum fractions, or ethane.  In an example, a cracked ethane gas containing 37 per cent ethylene and 43 per cent hydrogen is passed over a hydrogenation catalyst to reduce the acetylene, and fed with recycle gas to a preoxidation zone containing silver at 210 DEG  C. The product contains 4.5 per cent ethylene and 6 per cent oxygen, and passes over supported silver oxide at 290 DEG  C. and 10 atm. Ethylene oxide is scrubbed out, the gas being recycled apart from one third, which is purged to a second oxidizing zone.

Title: Improvements in and relating to the printing of photographic cinematograph films
IPC: G03B27/16
Filed: 1920-04-12
Abstract: 166,340. Lawley, H. V. April 12, 1920. Printing -apparatus.-In order to control automatically the printing-light for different sections of a negative film, the negative film passes through a gate b<1>, Fig. 2, having a number of contacts e<2> and 1 to 10, and the edges of the negative film are at the commencement of the sections, provided with positioned conductive contacts d<1>, d<2>, Fig. 3, by means of which a selected circuit through the contact e<2> and one of the contacts 1 to 10 is completed to control the printing-light. The contacts in the gate are mounted on insulated strips e<1>, the contact e<2> constitutes a terminal contact, and the circuit is completed through the contacts d' and d<2> by connected runners e<4> at the back of the gate. The means for controlling the lamp circuit l, Fig. 6, comprises two series of electromagnets g, g<1>, Fig. 4, arranged in pairs, each pair having an oscillating armature g<2> pivoted on a bus-bar h<2>. Each armature has a U-contact g<3> adapted to dip into mercury cups g<4> to complete the lamp circuit l, through a variable amount of resistance k. Each of the electromagnets g has a spring armature i<1> and a contact i<2> adapted to shortcircuit the other electromagnet g<1> across a circuit p, q, r, Fig. 6. The terminal contact e<2> is connected in series with the electromagnets g<1> and the battery, and the electromagnets g are individually connected to the contacts 1 to 10 and the bus-bar h<2>. When the negative film passes through the gate and the circuit through e<2> and contact 8, for example, is completed, the No. 8 electromagnet g is energized and completes the lamp circuit through the corresponding mercury cups g<4>; the No. 8 electromagnet g<1> is short-circuited ; and the other electromagnets g<1> are all energized to prevent any other armature from being operated. When the contacts on the film have passed through the gate, contacts i, i<2> spring apart and the short-circuit q is opened, the operative armature being held by a light spring g'. When another section reaches the gate, the electromagnet g, No. 8 is energized, this light circuit is opened and another of the electromagnets g energizes corresponding to the position of the contacts d<1>, d<2> for the next section. In lieu of the contacts d', d<2>, notches or perforations may be positioned and the circuit in the gate e completed bv resilient contacts springing through the notches.

Abstract: 352,471. Combined sound and picture films. STAHL, C., 37, Laubacher Strasse, Wilmersdorf, Berlin.-(Assignee of Freund, B. ; 30, M³nchener Strasse, Sch÷neberg, Berlin.) March 31, 1930, No. 10182. Convention date, April 2, 1929. [Class 98 (ii).] A combination sound and picture film record is made as a negative by first recording the sound and pictures on separate films, developing one of these, then transferring the developed record on to an unexposed portion of the undeveloped film which bears the other record, and finally developing the latter film. The transfer may be effected either (1) by contact printing from a positive derived as an intermediate print from the originally developed negative record, or (2) by using a reversal film for the initially developed sound or picture record, so that this is formed as a positive in the first instance, or (3) by using an electro-optical copying process, whereby a negative can be directly transferred as a negative. Fig. 3 shows a method of carrying out the process, in which a negative sound record 40 is passed across a beam of light from a source 41, which beam falls on a photo-electric cell 44. This cell controls, through an amplifier 45, a lamp 46, by means of which a replica of the negative sound record is formed on the portion 3 of the undeveloped picture film 1. Fig. 2 shows a method of contact printing from an original sound film 10 on to a shorter film 18. Light is directed on to a point 17 at which the films 10, 18 pass together over a roller 23, the film 10 moving more rapidly than, and in the same direction as, the film 18. In Fig. 5 is shown a device for enabling the correct printing exposure to be determined. A rotary shutter 60 carries a number of light filters 61, 62, &c., of varying density, separated by opaque bars 70. The shutter is mounted on a spindle 84 carrying a pointer 97 which moves over a scale. Light from a source 75 passes through the shutter, and is focused by an optical system on the print film 80 (the film from which the print is being made not being shown). A test print is first made whilst the shutter 60 is rotated intermittently, so as to produce a record which, after development, has the appearance shown in Fig. 4. By noting which of the separated sections 50, 51, &c., of the sound record has been correctly exposed, the shutter can then be set, by means of the pointer 97, so that the light filter which gives the best result intercepts the beam.

Abstract: 610,259. Lifting-jacks. LAYCOCK ENGINEERING CO., Ltd., and CHARLESWORTH T. R. April 3, 1946, No. 10262. [Class 78 (iii)] In mobile hydraulic jacks of the type in which the two ends of a common control lever pivoted to the operating handle serve respectively to push or pull a rod by which either locking of the handle or lowering of the load are correspondingly effected, the risk of accidental lowering is minimized by mounting a sleeve on the handle which must be turned to free the control lever. The jack is carried by a wheeled base 10, Fig. 1, and comprises a load-engaging crutch 12 carried at the end of a lever 15 which is raised by movement of a fluid-pressure operated cylinder 21. At the free end of the operating handle 28, a control lever 65, Fig. 5, is pivotally attached at 62 to the wall of the operating handle, the arm 72 of the control lever being received by a slot 63. Coupled to the lever within the handle is a control rod 56 providing connection to the lowering and handle-locking mechanisms. Rotatably mounted on the handle between the control lever and a T-bar 60 is a sleeve 68, provided with a slot 70, the control lever being freed for movement into the lowering position to exert a pull on the control rod when the slots 70 and 63 are in alignment, and freed for movement into the handle locked position to push the control rod when the slot 70 and pivot 62 are in alignment. The slot 70 is sufficiently wide so that after the side 73 of the lever has entered the slot the sleeve can be further rotated to bring a projection 76, Fig. 8, into abutment with the side 72 of the control lever to prevent its accidental return from the handle locked position. A ball-catch 74, Fig. 5, locates the sleeve in its various positions.
