Title: Improvements in tension regulating arrangements for elongate non-rigid elements
IPC: B65H59/10
Filed: 1960-04-11
Abstract: 945,953. Feeding webs. COMPAGNIE FRANCAISE THOMSON-HOUSTON. April 11, 1960 [April 9, 1959], No. 12926/60. Heading B6B. [Also in Division D1] A device for regulating the tension in an elongate non-rigid moving element (e.g. strip) comprises a first rotatable member over which the element passes and which is driven relative to the element and a second member freely rotatable by the element passing over it, the axis of the second member being movable relative to the driven member to vary the length of element contacting the driven member. As shown, a wire 1 passes over a capstan 3 driven about an axis O, over a freely rotatable pulley Q, and about a pulley P freely rotatable about the axis O before passing to a support 2 to be wound. The pulley Q is mounted on an arm 4 which is rotatable about the axis O and is fast with a pulley M about which a wire 5 is wrapped and weighted by a weight P to give a constant anti-clockwise couple acting on arm 4. Because of the difference in radii of capstan 3 and pulley P the tension in the wire 1 causes a clockwise couple to act on the arm 4 which therefore takes up a position such that the opposing couples are equal. The tension F 1  in the elongate element downstream of the capstan is therefore maintained constant irrespective of the tension F 2  upstream of the capstan. In the form shown capstan 3 is driven clockwise to make tension F 1  less than tension F 2 . If F 1  is to be greater than F 2  then capstan 3 should be driven in an anticlockwise direction, the couple produced by the weight P should be reversed and the radius of the capstan should be made greater than the radius of the pulley P.

Title: Process for the production of metallic manganese and if desired pure manganese dioxide
IPC: C25C1/10
Filed: 1941-10-08
Abstract: 545,724. Manganese dioxide. SOC. METALLURGICA ITALIANA and GUARESCHI, -P. Oct. 8, 1941, No. 13012. Convention date, Oct. 8, 1940. [Class 1 (iii)] [Also in Group XXXVI] Pure metallic manganese and MnO 2 are obtained from pyrolusite or other source by treatment with sulphuric acid in the presence of a reducing agent such as a ferrous salt which converts the MnO 2 to MnO, the reducing agent being then precipitated as ferric hydrate by neutralization of the solution by CaCO 3 or NH 3 in the presence of ammoniacal salts or by means of the spent catholyte from the electrolysis step, the solution being then electrolyzed in a partioned cell. The precipitate contains the iron, antimony, arsenic etc.; copper, zinc, cadmium &c. present are precipitated by addition to the solution of pure electrolytic manganese in powder form. MnO 2 may be added to the solution before the neutralization step. The ferric hydrate may be regenerated by dissolving it in H 2 SO 4  in the presence of SO, or an alkaline sulphide, or the spent anolyte obtained from the electrolysis may be employed for this purpose ; this may also be used for the solution of the mineral.

Title: Calibration arrangement for flow meters
IPC: G01F25/00
Filed: 1965-03-26
Abstract: 1,038,287. Calibrating flow meters. ROCHAR ELECTRONIQUE. March 26, 1965 [April 1, 1964], No. 13044/65. Heading G4H. A flow meter is calibrated by passing through it a volume of liquid measured by a piston and cylinder producing a large number of pulses per circuit volume, the pulses being applied to a counter during an interval which is the time taken for the meter under test to register a given volume, the difference between the counter reading and a theoretical number giving the meter error. The cylinder 10 has its ends connected together via pipe 16 and the flow meter 18 under test. Piston 22 in the cylinder is displaced by nut 28 engaged with threaded rod 30. The rod is rotated by motor 34 through reduction gear 32 and a disc 36 on the rod generates photoelectrically a thousand pulses for each litre of liquid forced through the meter 18 by piston 22. The output pulses of the meter 18 are amplified at 46, divided by N (160) at 48 and applied to gate 50. The pulses from disc 36 are applied via gate 60 to counter 64. Gate 60 is opened for a measured interval by clock 62. A manometer device 44 measures the pressure difference alross the meter 18 and this is plotted at a on recorder 68. The output of divider 48 is plotted at b and is a square wave the duration of which is the time taken for meter 18 to make 160 revolutions, representing 10 litres. This signal opens gate 50 allowing the pulses from disc 36 to pass to counter 56. If meter 18 is accurate there should be 10,000 pulses during this period. The counter has four decades and should therefore return to zero. Any error is indicated on the counter, the value being complemented if necessary and the sign of the error indicated at 58. The speed of rotation of rod 30 may be varied to test the meter at different flow speeds. To test the tightness of piston 22 valve 40 is closed to introduce a restriction 42 in the meter loop. This increases the pressure differential on the piston and the leakage, if any. Tests are again made on the meter 18 and the results compared. If they are identical the leakage is zero. In a modification the piston is displaced in the cylinder by pressure generated by a pump. Displaced liquid passes through the meter under test and pulses are derived to measure the volume displaced by the piston as before.

Title: Aircraft
Inventor: DAVIDSON IVOR MACAULAY
IPC: B64C27/26
Filed: 1961-04-13
Abstract: 948,947. Aircraft wings. POWER JET RESEARCH & DEVELOPMENT CORPORATION. Oct. 2, 1961 [April 13, 1961], No. 13290/61. Headings B7G and B7W. An aerofoil is of substantially circular section with at least two spanwise-extending apertures arranged to discharge fluid streams as thin layers upwardly and downwardly towards one another over the rearward part of the aerofoil surface, and has means for varying the relative momentum of the two streams. Fig. 1 shows an aircraft having wings 2 with padded jet propulsion by-pass gas turbine engines 5, and a rotor having two blades 9 with tip jet units 10, these blades, when the aircraft is supported by wings 2 during cruise, being received in longitudinal recesses in the fuselage and retained by locks 14. For take-off or landing, each blade is raised by jacks 11 about its pivot 33 on a hub 7 (Fig. 2) and then locked to the hub by a catch 36 engaging a flange 32a fast to the blade. Doors 15, Fig. 1, fold back to permit rotation of the rotor. The hub is faired by a dome 8. Each blade is of the section shown in Fig. 3, an inner duct 54 conveying gases from the engines 5 to the tip jet unit when operative, and an annular duct 53 conveying air from the by-pass compressors of engines 5 to slots 71, 72, 73, 74 and 75 which discharge over the lower rear quadrant of the blade to produce a stagnation point at P, and generate lift as the blade moves in the direction of arrow A. The slots 74 and 75 are of variable area, Fig. 4, one edge of each slot being a flexible strip 81a, 81b anchored to the blade skin 51 at one end and movable by an inflatable bag 82a, 82b. The areas of the two slots 74, 75 of each blade are varied in opposite senses by displacement of the piston 87a of an hydraulic master cylinder 88a. The two pistons are movable together for collective lift control by a jack 95 which bodily displaces a swash plate 91. Cyclic lift control is obtained by tilting the swash plate by two jacks 96 (one shown). Fig. 2 shows the hub construction, a tubular member 21 being mounted by ball races 22, 23, in fixed structure 24. Ducts 41 deliver engine exhaust gases to an annular manifold 43 communicating with the interior of member 21 and branch ducts 35, through ports 44. When each blade is raised about pivot 33 by jacks 11 (Fig. 1), the inner duct 54 mates with a branch duct 35. A liner 27 in member 21 forms an annular chamber 28, fed with by-pass compressor air from ducts 61 through manifold 63 and ports 64. Outlet ports 65 feed fixed ducts 66 (shown in Fig. 1) which register, when the blades are raised, with openings 67 in the blades to supply the annular ducts 53. The discharge area of one of apertures 71, 72, 73 may be variable as well as or instead of that of aperture 74. A further rearwardly discharging aperture may be provided. If aperture 74 is above the rearward extremity of the blade, aperture 75 is rearward of the lower extremity. The lift may be controlled by valves in the air supply to the appropriate apertures. Specification 944,010 is referred to.

Filed: 1919-05-29
Abstract: 136,762. Pedersen, P. O. March 4, 1919, [Convention date]. Electric oscillations, producing; discharge-gap apparatus.-Relates to improvements in Poulsen arc-generators for high-frequency currents, and is designed particularly with a view to securing high efficiency in coupled circuits, more especially in the case of aerials having small capacity or great resistance. According to the invention, the cathode is provided with cooling or other means which will restrict the travelling outwards of the arc due to the magnetic field and regulate the temperature at the starting point for a properly high starting-voltage. The electrodes are also so arranged relatively to one another that the increases in length and resistance of the arc during its travelling are restricted to the most favourable values. Fig. 2 shows a limitation of the travel of the arc from position a to position b by the use of a water-cooled copper pipe A bearing against, or fixed near, the cathode. In a modification, the cathode may be surrounded at the desired point by a water-cooled collar. Fig. 4 shows a cathode proper K with a back-piece B of poorly-conducting carbon or of relatively infusible metal. The arc tends to be blown out at the point b. Or the back piece may be omitted, the arc being blown out on the rear edge of the cathode K, the length of which is suitably chosen. Fig. 6 shows the anode and cathode parallelly displaced, with the anode profiled to secure an appropriate lengthening of the are between positions a' and b<1>. The starting and extinction voltages are controlled by local cooling at variable points e, d by currents of gas or liquid supplied through blowpipes. The blast may consist of hydrogen, coal-gas, alcohol, ether, &c. Fig. 7 shows a water-cooled cathode inclined at an angle to the anode. A water-cooled pipe D is applied near the cathode to fix the starting-point a, and a blow-pipe f fixes the blow-out position.
