Title: Improvements relating to riveting apparatus
IPC: B21J15/34
Filed: 1944-03-22
Abstract: 578,105. Apparatus for setting tubular rivets. AVIATION DEVELOPMENTS, Ltd., and SPOONER, R. A. W. March 22, 1944, No. 5323. [Class 43] Relative reciprocation of the parts of a riveting gun is effected pneumatically or hydraulically under the control of a device which may admit pressure to or relieve pressure from a chamber in which is a piston which serves to move the barrel of the gun against a restoring force, such as a spring, or to effect the reverse movement. The controlling device may be in the form of a push button 83 on the hand grip 6 of the gun, which controls a valve 78 to relieve the pressure in an air pipe line 73 to atmosphere, or alternatively to maintain the pressure. In the former position, a piston 71 in a cylinder 72 of a compressed air apparatus, which is coupled at 76 to a source of compressed air, is moved to the left, to apply pressure from an oil cylinder 94 to an oil pipe line 70 which leads to an annular space between the barrel 7 and casing 1 of the gun and behind a piston carried by the barrel. When the riveting jaws 22, 23 (Fig. 2, not shown) are pressed against the flanged head 21 of a rivet 12 inserted in work pieces 92, 93, and the button 83 is operated to relieve the pressure in pipe line 73, the casing 1 is moved rearward to draw the headed mandrel 9 through the bore of the rivet and upset it. Reverse movement of the button which is effected by a spring in the valve 78 allows a spring in the above-mentioned annular space between the casing and barrel of the gun, or fluid pressure, to restore the barrel and casing with mandrel 9 to position. during which movement a rivet is fed forward between the jaws 22. 23 to position for a further riveting operation. Instead of operating the controlling device by a push button, a treadleoperated control may be employed. Separate pipes may serve to relieve and supply pressure fluid to the gun. Specifications 578,104, 578,106 and 578,107 are referred to.

Patent GB-415408-A (GB)
Title: Treatment of cellulose nitrates
IPC: C08B5/10
Filed: 1933-02-22
Abstract: Cellulose nitrate is heated at temperatures above 100 DEG  C., but at atmospheric pressure in an aqueous medium containing a soluble salt of hydrochloric acid in the presence of an oxidant.  The treatment effects purification, bleaching, clarification, and reduction of viscosity of the nitrocellulose.  The salt is preferably common salt or magnesium chloride, and the oxidant is nitric acid.  A non-oxidizing acid may also be present and in this case the nitric acid may be provided by hydrolysis of part of the nitrocellulose. The nitric acid may be added in admixture with sulphuric acid.  The treatment liquid may contain a solvent or swelling agent for the nitrocellulose such as triacetin.  In an example, nitrocellulose of 11 per cent nitrogen content and of high viscosity is drowned in a large amount of water and drained. It is then boiled with a saturated solution of brine, the water in the damp material being allowed for by the addition of dry salt. The brine is rendered acid by adding a small proportion of nitrating acid.  The treatment is continued for one or more hours according to the reduction in viscosity desired. The material is bleached by chlorine liberated by the action of nitric acid on the boiling brine.  The stability as indicated by methyl violet paper, and the solubility and clarity in alcohol and camphor-alcohol are greatly increased.  In another example, the acceleration due to the presence of triacetin is shown.  In another example, transparent cellulose nitrate plastic scrap is cut into small pieces and then treated with boiling brine of slight acidity. Chlorides of any of the alkali metals and chlorides of alkaline earth metals may be used except where the formation of insoluble sulphates would be objectionable.  The treated products are suitable for the production of lacquers, plastics, and particularly of safety-glass for motor-car windscreens.

Abstract: 712,143. Fuel - injection pumps. SULZER FRERES SOC. ANON. March 4, 1952 [April 3, 1951], No. 6663/62. Class 102 (1). [Also in Group XXVII] An internal-combustion engine fuel supply system comprises a fuel injection pump connected to a fuel injector valve by a pressure pipe, a fuel heating device, a circulating system for the heated fuel which includes the suction space of the injection pump, and means for diverting the flow of the circulating heated fuel from the suction space of the pump through the pressure fuel pipe when the injection pump is not delivering fuel under pressure for injection. In Fig. 1 a feed pump 2 delivers heavy fuel through a heater 4, heated by steam, to the suction space 8 of an injection pump 9 from which a portion of the fuel is delivered through a pipe 15 to an injector 14 whilst the remainder is circulated through a pipe 10 back to the tank 1. Prior to starting, the valve 11 is closed and valves 12, 13 in the injector 14 are opened, whereby the heated fuel is diverted past the valves 16, 17 in the pump and through passages 21, 23 in the injector to a return passage 20. When the pump and injector .are sufficiently warmed, the valve 11 is opened and valves 12, 13, closed to revert to normal running conditions. In a modification, Fig. 2, in which two pumps 9 feed separate injectors 14', a single valve 35 controls the changeover from the warming-up condition to the normal-running condition. A single pump 2 feeds the fuel through an electric heater 52 to the pump suction spaces 8, from which the surplus fuel is circulated through passages 10', 10" back to the tank. Prior to starting, the valve 35 is rotated to the position shown in Fig. 2 in which the passage 10<SP>1</SP> is closed and a passage 36 connects a compressed air pipe 37 to passages 39 whereby valves 43 in the injectors are opened to permit the heated fuel to flow through the pumps and back to the tank 1 through the passages 21, 23' in the injectors. To begin injection, the valve 35 is rotated through an angle of 90 degrees whereby the passage 36 interconnects the passages 10<SP>1</SP>, 10<SP>11</SP> and a passage 46 rents the pipes 39 to atmosphere to allow the valves 43 to close. Part of the heated fuel returned to tank 1 is cooled in a heat exchanger 59 in which some of the fuel flowing to the pump 2 is preheated. The fuel from the pump 2 may be heated by hot water, exhaust gases or electrically. Specification 700,662, [Group XXVII], is referred to.

Filed: 1930-02-24
Abstract: 346,912. Reducing electric charge in textile fibres. ACETA GES., 9, Haupstrasse, Lichtenberg, Berlin. Feb. 24, 1930, No. 6070. Convention date, March 11, 1929. [Classes 2 (ii) and 15 (ii).] The electric charge of textile fibres, particularly artificial fibres from cellulose esters and ethers, which is formed during the working up thereof, is reduced by treating the fibres with mixtures of oils or fats to which an oil soluble organic base has been added. Fat-acids may also be present. As examples of suitable bases are mentioned cyclohexylamine, dibutylamine, hydrogenated pyridine bases such as piperidine, amino-alcohols such as the mono-di- and tri-ethanalamine, the products known under the trade name of Sapamines as, for instance, oleic acid-#-aminoethylamide. Soaps of secondary or tertiary amino-alcohols and of the sapamines are particularly suitable, and bases combined with fat-acids of low melting-point, such as olein or technical olein are preferred. The presence of amino-soaps increases the suppleness and slipping power of threads in knitting, facilitates the subsequent washing operations, and such substances as amines or amido-soaps act towards the oils as antioxygens and retard resinification of the oils by atmospheric oxygen during storage of the textiles. Either the fat-acid or the base may be in excess in the mixture, and a base in the proportion as low as 0À2 to 2À0 per cent may be used. In examples given for the treatment of artificial threads, coco nut oil, olein, castor oil, palm kernel oil, and arachis oil are mentioned. German Specification 286,173 is referred to.

Abstract: 697,218. Automatic feed weighers. TOS HOSTIVAR, NARODNI PODNIK. March 10, 1952 [March 8, 1951], No. 6220/52. Class 143 Material is discharged from the pan of an automatic feed weigher by means of a conveyer belt which lies slack in the scale pan until the required weight has been supplied from a feed hopper. The belt is then tightened and driven and the load is removed. The belt 15, when slack, lies in the bottom of a channel-shaped pan 7 suspended from the beam 1 of the weigher. Material is supplied from a hopper 28 under the control of a pivoted gate 29. At a predetermined load, unspecified apparatus shuts off the feed, locks the scale pan and causes the pulleys 16, 17 to swing outwards to the position shown. This tensions the belt, raising it clear of the scale pan, and, since pulley 16 is driven via gearing from a rope 23, the belt is moved to discharge its load. In a modification, Figs. 4 and 5 (not shown), both tensioning pulleys are idlers, a third pulley providing the drive. It is stated that the belt may be driven in one direction for correct loads, and in the other for incorrect loads, or for selective sampling,
