Abstract: 1278536 Film feed apparatus MULTISCREEN CORP Ltd 18 Nov 1970 [24 Nov 1969] 54731/70 Heading G2E A rolling loop film transport mechanism for cinematographic apparatus, as shown a projector 60, comprises a stator 73; a rotor 94 co-operating therewith to define a passage for film 72, the rotor having gaps 150, Fig. 9, for receiving film loops 246, Fig.16; the stator having a film inlet defined by a guide 74 and a portion 83 and an outlet defined by a guide 78 and a portion 84, there being an aperture 79 intermediate the guides 74, 78; sprockets 70, 76 for feeding film into the inlet and out of the outlet at a controlled speed relative to the rotor speed; stationary pins 241, 250, Figs. 12 and 16, for intermittently holding said film stationary in registration with the aperture 79, and also for co-operating with the sprockets 70, 76, for gradually increasing and then gradually decreasing a film loop in a gap; and decelerating pins 234 coupled to the stator 73 which act to reduce the impact between the film 72 and the fixed pins 241, 250. Adjacent the film inlet of the stator is provided a manifold 163, Fig. 9, which receives a pressurized pulse of air as the trailing side of each gap 150 approaches a newly formed loop adjacent the inlet guide 74, thereby cushioning the impact of the gap 150 on the loop. Simultaneously the air pulse passes, via a pipe 110, to the preceding gap which is aligned with the aperture thereby blowing dust particles off a lens 105, Fig. 7. Also, to stabilize the film position and to reduce friction, air is fed from pipes 112 to orifices downstream of the inlet. Suction is provided to keep the film flat in the aperture 79. The sprockets 70, 76 and the rotor 94 are driven via toothed belts and wheels by a motor (118) Fig. 7A (not shown), which motor also drives cam mechanism 86 controlling the movement of the decelerating pins 234. Since the rotor has eight gaps, the sprockets feed one frame length of film and the cam mechanism completes a full revolution for every # revolution of the rotor 94. A primary shutter 152, Fig.16, is associated with each gap, while secondary shutters 154 are provided one between two gaps, so that each film frame is projected twice. The projector lens holder 258 is slidable in vertical runners 260, 262 and is easily replaced by a clean lens. If the transport mechanism is to be used in a camera, then the secondary shutters are omitted.

Abstract: 566,013. Metallic fluorides and sulphates; sodium and potassium sulphates. WELCH, A. J. E. March 17, 1943, No. 4359. [Classes 1 (ii) and 1 (iii)] Simple or complex anhydrous metallic fluorides, or oxyfluorides, and anhydrous metallic sulphates or basic sulphates, are prepared by heating to 600-1000‹ C. a mixture of a compound (e.g. oxide, silicate, sulphide) of a metal with a simple or complex fluoride of an alkali metal or alkaline earth metal (or other metal whose sulphate or basic sulphate can exist under the conditions of the reaction) in the presence of sulphur trioxide. The sulphur trioxide may be formed by introducing sulphur dioxide and oxygen into the reaction chamber, or by including a sulphate, e.g. magnesium sulphate, in the reaction mixture. When a sulphide mineral is used in the reaction, the supply of sulphur dioxide may be omitted or reduced, but oxygen or air must be present. By altering the temperature and the proportions of reactants used, the end-products may be varied. Examples describe the preparation of sodium aluminium fluoride and aluminium sulphate. from aluminium oxide, lithium and nickel sulphates from silicate minerals of these metals, and sodium zirconium fluoride and the corresponding beryllium, niobium and tantalum salts from zircon, beryl, niobite and tantalite respectively. Potassium salts may be obtained by using potassium fluoride in place of sodium fluoride in the reactions described in the examples.

Title: Process for the production of methane from carbonaceous fuels
IPC: C10K3/00
Filed: 1971-12-07
Abstract: 1360645 Methane production TEXACO DEVELOPMENT CORP 7 Dec 1971 [18 May 1971] 56674/71 Heading C5E Methane is produced by continuously introducing oxygen, carbon monoxide, hydrogen, optionally H 2 O, and a carbonaceous fuel into an unpacked reaction zone 3 maintained at a pressure of 300 to 4500 pounds per square inch and an autogenous temperature of 1200 to 2200‹ F., wherein the relative amounts of oxygen and carbonaceous fuel are sufficient to effect conversion of at least 70% of the carbon contained in the carbonaceous fuel into gaseous reaction products while maintaining an average temperature in the reaction zone within the temperature range; discharging as an effluent stream from the reaction zone products of reaction comprising carbon monoxide, hydrogen, methane, carbon dioxide and water vapour; separating water and carbon dioxide from the effluent at 17 and 21; and separately recovering substantially pure methane from the effluent at 24. Substantially all the carbon monoxide and hydrogen in the effluent may be recycled to the reaction zone via line 7. The carbonaceous fuel may be a hydrocarbon of higher molecular weight than methane and may be solid or liquid, e.g. ethane, propane, butane, liquefied petroleum gas, gasoline, naphtha, kerosine, crude petroleum, shale oil, tar, sand oil, cycle gas oil from fluid catalytic cracking, furfural extract of coker gas oil, Udex raffinate, asphalt, coaltar, petroleum coke, bituminous, anthracite and cannel coal, lignite, gilsonite, refinery waste gases, oxygenated hydrocarbonaceous materials such as alcohols, ketones, aldehydes, phenols and carbohydrates. The relative amounts of oxygen to carbonaceous fuel may be 0À6 to 1À0 oxygen atoms per carbon atom, and that of water may be 0À0 to 2-0 pounds water per pound of carbonaceous fuel. The oxygen may be introduced as an oxygen-rich stream containing at least 95 mol. per cent oxygen. 70 to 97% of the carbon may be converted, with the unconverted solid carbon in the effluent stream being separated and recycled as part of the carbonaceous fuel; if the fuel is liquid the carbon is recovered from the effluent by contact with the fuel in tower 11 and recycled via line 6.

Filed: 1969-11-20
Abstract: 1,269,284. Feeding sheets. MABEG MASCHINENBAU G.m.b.H. NACHF HENSE & PLEINES G.m.b.H. & CO. 20 Nov., 1969 [7 Dec., 1968], No. 56914/69. Heading B8R. A device for detecting a sheet with a folded corner 50, Fig. 3, or extraneous matter such as a piece of paper 53 in a stream of sheets being fed from a pile 65 to a printing or other machine comprises an elongated member supported transversely of the flow of sheets so that normally the sheets pass under the member without exerting upward pressure thereon, but so that a corner-folded sheet, etc., moves the member causing actuation of means for stopping the sheet feeder and the printing machine. Means are also provided whereby any movement of the detector device caused by the leading and trailing edges of an overlapping stream of sheets passing the member does not effect stopping of the feeder. As shown, three axially-aligned rollers 7, 8, 9 are employed and are carried by frames 22, 25; 16, 17; 23, 60 respectively independently pivoted about a shaft 3 and are situated above a feed roller 48. The frame arms 16, 17 carry nozzles 18, 19, the nozzles 18, 19 normally being closed by members 20, 21 on the frame arms 22, 23. The frame arm 25 causes a closure member 24 normally closing a nozzle 26 carried by an arm 27 pivoted on the shaft 3. The nozzles 18, 19 are connected to a fluid-pressure chamber 33 separated by a diaphragm 34 from a similar chamber 31 connected to the nozzle 26. A switch 35 is connected to the diaphragm 34, and the fluid pressure in the chambers 31, 33 supplied from a source 40 is adjusted by valves 41, 42 so that the switch 35 is normally open. If either of the rollers 7 ... 9 is moved by a folded corner or by extraneous matter on a sheet, one or both of the members 20, 21 are moved to open the nozzles 18, 19 thus releasing the pressure in the chamber 33, closing the switch 35, and causing stopping of the feeder. The rear and leading edges of the sheets may cause temporary lifting of all the rollers in unison, and such movement merely causes opening of the nozzle 26 connected to chamber 31 so that there is a tendency for the diaphragm 34 to move to the left, i.e. the valve 35 is not closed by such lifting. The initial position of the rollers 7, 8, 9 with respect to the roller 48 and stream of sheets can be adjusted by screws 47 engaging the extreme frame members 25, 60.

Abstract: 1325375 Solid/gas contact; preparation of catalyst P P ANDREICHEV 1 Dec 1970 56945/70 Heading B1F Catalyst is formed when granular stock material to be treated enters at 2 and 3 and falls down tube 1, hot reducing gas enters at 5, which gas is at a temperature not less than the temperature of the stock material at the end of reduction, cold reducing gas enters at 6 and oxidising gas if required enters at 7. Further heated gases may be passed in through conduits 8, 10 and 16. The rate of catalyst discharge is controlled by belt 11. Thus a granular stock material comprising oxides of iron introduced at 2 or 3 falls down through the reactor, and a passivating gas at 15-35C is fed in through 7, a reducing gas at 15-35C is fed in at 6, and a hot reducing gas is fed in at 5 so that it mixes with the other gases to form a temperature of 500-550C entering the bottom of chamber A. The treatment of a zinc and chromium oxide stock material with a reducing gas is also exemplified.

Title: Circuit arrangements for range measurement in a radar unit
IPC: G01S13/70
Filed: 1972-12-27
Abstract: 1377032 Pulse radar SIEMENS-ALBIS AG 27 Dec 1972 [21 Jan 1972] 59665/72 Heading H4D  In a radar unit a first, fast response, range measuring device initially tracks a target while a high inertia, but accurate range measuring device catcher up with the target, tracking eventually being transferred to the second device, the system including means to enable the first device to be set to a second target while the second device is tracking the first target so that tracking of the second target can be started when desired i.e. when tracking of the first target can be terminated. It is stated that the system can operate with smaller range gate widths than prior out systems. A range gate 1 is initially connected to a fast response range measuring device 2, the echo pulse being applied at Z. Switches 9a, 9b, 9c are then in the position shown. Devices 1, 2 form a tracking system for the target. A second range measuring device 3 is connected by a mechanical shaft 11 to a computer 5. Both devices 2, 3 give pulses indicating the range value being tracked and these pulses are fed to a device 4. The output U4 of this device corresponds to the difference in the range values in devices 3, 2. Output U4 is fed via switch 9a to device 3 so that the range value stored in this device'is shifted towards that in device 2. Eventually the range values in devices 2, 3 are nearly equal and, when they are closer than a threshold, switch 8 causes switches 9a, 9b, 9c to change over so that device 1 is now connected to range measuring device 3 which proceeds to take over the target tracking. As switch 9a has changed over the output of device 4 is connected to device 2 which is thus slaved to the range value in device 3. If another target is to be tracked, switch 12 is operated to connect a second output of device 3 via a delay 6. The delay is adjusted to cause the range stored in device 2 to be that corresponding to the expected locality of the second target. A display 10 gives light markers corresponding to the pulse from devices 2, 3 at their respective time positions, delay 6 being adjusted until the light marker from device 2 is at the position corresponding to the new target. By placing switches 9a, 9b, 9c back into their initial positions devices 1, 2 again form a tracking system which now tracks the new target. As before, device 3 eventually takes over the tracking.
