Title: Improvements in or relating to rotary stitchers
IPC: B42B4/02
Filed: 1938-10-07
Abstract: 519,247. Stapling. GOSS FOSTER, Ltd. Oct. 7, 1938, No. 29146. Convention date, Oct. 7, 1937. [Class 89 (iii)] In a rotary stapling mechanism, a stapleforming and driving device is mounted at each end of a cylinder 21 so as to lie within the periphery of the cylinder between its flat end and an attached ring 33. Each device comprises fixed outside formers 25, 31 formed with stapleforming grooves 26, 32 which are slightly non- radial with respect to the axis of the cylinder. The staple wire is forced into the grooves by fingers 86, 87 on a rotary carrier 41 which is so mounted that the fingers project into the space between the formers 25, 31 as the cylinder and carrier rotate. Wire w is fed to guide block 76 and held by a spring 79, and a staple-length is then cut off by cutters 72, 73 on the cylinder and carrier, is carried forward by notches on the fingers 86, 87, and is shaped by being forced into the grooves 26, 32. Its cross-bar is supported by a block 61 pivoted at 66 and connected to a rock-shaft 67. As the cylinder rotates further, the staple is carried off the fingers 86, 87 and on to an arcuate horn 54 which is fixedly mounted concentrically with the cylinder 21. The horn supports and guides it up to the driving position, where it is driven by a short reciprocation of the block 61 and clinched by an anvil 2 on a gathering and folding cylinder 1. The horn has a reduced, upwardly-curved end which extends between the fingers 86, 87 at the staple-forming position, and the block 76 has a tongue 77 extending between the fingers at the wire-feeding position.

Abstract: 1,084,497. Dropping loads from aircraft. G.Q. PARACHUTE CO. Ltd. May 16, 1966 [July 9, 1965], No. 29183/65. Heading B7G. A method of unloading a plurality of loads, e.g. parachutists, from the rear door 27 of an aircraft, wherein the first load 18 to be unloaded from the aircraft extracts the parachute pack 21 of the second load to be unloaded which opens to extract through a line 29 the second load and the parachute of the third load, the sequence repeating until all the loads to be unloaded have been extracted. The first load 18 may be extracted by a parachute 28 itself extracted by an extractor parachute 24. Each load may be accommodated in a separate compartment (12-17), Fig. 1 (not shown), having transparent sides and each is connected to the parachute pack 21 of the following load by a line 23. To allow separation between the loads the line 23 may extract the pack 21 from the enclosed parachute (30) or alternatively may incorporate break ties which sever. The parachutes may extract the loads while in a reefed condition and may subsequently be automatically de-reefed. Instead of accommodating the loads in compartments, the loads may be supported on mats (45), Figs. 8 and 9 (not shown), having friction devices (47) for reducing the acceleration thereof. When the mats reach the end of their movement break ties are arranged to be severed so as to release the load from the mat for extraction.

Title: Improvements in methods and devices permitting automatic calculation of correlation functions
Inventor: BONNET GEORGES
IPC: G06F17/15
Filed: 1963-07-23
Abstract: 1,046,278. Correlation calculators; electric selective signalling systems. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 23, 1963 [July 30, 1962]. No. 29195/63. Headings G4A and G4H. [Also in Division G1] In a method of calculating correlation functions, the values of the signals to be treated are quantized in bands, the width of which are proportional to the mean quadratic deviation of the signals treated. It is shown that this condition gives a constant quality factor for the calculation over a wide range of values of the mean quadratic deviation. In the auto-correlation circuit of Fig. 5, an input signal at terminal 11 passes direct to a quantization unit 16 and through a delay unit 15 to a quantization unit 17. A voltage proportional to the quadratic deviation of the signal is derived from the signal of a rectifier 30 and filter 31 and fed to a potentiometer chain of equal resistances 20a- 20f, to the taps on which the signal is compared in units 16 and 17. The quantized signals are multiplied in unit 27, integrated in unit 28 and amplified in amplifier 34 to give the autocorrelation function. It is shown that the gain of amplifier 34 should be proportional to the square of the quadratic deviation, and this is achieved by a rectifier 35 and filter 36 controlling amplifier 34. To derive a cross-correlation function the second input signal is fed to delay unit 15 and a separate circuit is provided for giving the quantization levels for the second signal. Fig. 6 shows a circuit for the quantizing, multiplication and integrating units. Voltages representing the desired quantum levels are supplied on lines 26a-26f to comparator units 43a-43f and 44a-44f. These may comprise bistable multivibrators with two cathode-coupled triodes or two emitter coupled transistors, and they are also supplied with signal voltages on lines 13b and 14b. The outputs of the comparators pass to anti-coincidence circuits 49a- 49e and 50a-50e arranged so that an output is obtained only from the most significant comparator tripped by the input signal. The output lines 41a-41d and 42a-42e are connected to a matrix of " AND " gates 59 which performs the multiplication. Each " AND " gate is connected to a transistor 64, the cathode resistance 68 of which is inversely proportional to the logical product represented by the gates; " AND " gates representing the same logical product may be connected through an " OR " gate 63 to a common transistor 64. The output from the transistors is integrated in a low-pass filter 28. The widths of the quantum bands may be equal to about three times the mean quadratic deviation of the noise accompanying the signal.

Title: Manufacture of sodium chlorate
IPC: C25B1/26
Filed: 1952-11-19
Abstract: <PICT:0714234/III/1> In the manufacture of sodium chlorate by electrolysis of sodium chloride solution, the solution is circulated in the interpolar space between cathode and anode at such a speed that the OH-ions from the cathode cannot reach the anode, the products of electrolysis NAOH + Cl2 thus being carried out of the p interpolar space and allowed to react to form sodium hypochlorite which is transformed to chlorate and chloride by chemical means. The solution, without separation of chlorate may be recycled until the desired conversion is attained.  In the drawing sodium chloride solution from tank 13 is passed by pump 15 and line 14 to vat 16 from which is regulated quantities it is fed by line 17 to an inlet chamber 5 of the electrolysis cell.  The solution passes up between graphite anode 2 and surrounding cylindrical cathode 1 at a speed correlated to the migration speed of the OH-ions to prevent them reaching the anode, and enters chamber 3.  The caustic soda and chlorine unite to form sodium hypochlorite whilst hydrogen also from the electrolysis is withdrawn at 7. The hypochlorite solution leaves chamber 3 by pipe 8 and enters chamber 10 when the hypochlorite breaks down to chloride and chlorate.  An equation relating the rate of hypochlorite-chlorate transformation to pH, temperature and concentration of hypochlorite ions is given.  Temperature, not exceeding 50 DEG C. and pH between 5.5 and 7.5 are preferred and are obtained by adding hydrochloric acid, for example, at point 9 before the reactants enter tank 10.  The solution then passes to tank 13 optionally through a heater 23, and the solution is recycled until the chlorate content is sufficient when it is withdrawn at 31 and new chloride introduced at 30.  If desired several such installations may work in series, the pump 15 delivering solution from tank 13 of one to the vat 16 of the next.  In an example the cathode anode assembly had a height of 64 cms., the interpolar distance was 1 cm. and the anode diameter 6 cms.  The current was 36 amperes and the minimum electrolyte flow rate was 2 litres (but preferably 10) per hour.  The electrolysis temperature was 40 DEG  C. and the average pH 7.5.

Abstract: 635,029. Valve amplifying circuits. HIGHAM, E. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 6, 1947, No. 29616. [Class 40 (vi)] In a direct-coupled amplifier an intervalve coupling is constituted by a discharge device of the kind having a voltage stabilizing characteristic, which discharge device has its anode connected to the anode of the preceding valve and its cathode connected to the grid of the succeeding valve, together with a constant current device connected between said grid and a source of negative biassing potential. As shown, a neon tube N is connected between the anode of valve V1 and the grid of valve V2, and a pentode V3 in series with a variable resistor R3, is arranged as the constant current device. The voltage across the neon tube will be approximately constant and obtained with a relatively small ohmic resistance, and the resistance of the valve V3 will be relatively large for a relatively small voltage drop. In this way a high coupling efficiency is maintained and considerably less biassing voltage required than in a resistance-coupled arrangement..
