Title: Improvements in or relating to shock absorbers
IPC: F16F5/00
Filed: 1948-06-04
Abstract: 660,268. Hydraulic shock-absorbers. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. June 4, 1948. [June 5, 1947] No. 15192/48. Class 108(iii). A shock absorber cylinder is divided into two chambers 7, 8, by a diaphragm 9, and the piston 2 which operates in the chamber 7 has a piston rod 3 on one side extending away from the diaphragm 9 through a high pressure liquid-tight packing to the exterior of the cylinder, and on the other side a plunger 10, of smaller cross-section than the rod 3, a restricted passage for liquid from one chamber to the other being provided through the diaphragm around the plunger which varies in cross-section along its length to vary the area of the passage over the stroke of the piston. As applied to a liquid-spring type shock absorber for aircraft landing gear, the plunger 10 has grooves 12 the cross-section of which vary in an axial direction. A valve 14 controlling flow through an orifice 13 in the diaphragm 9 is urged to an open position by a spring 15. A stem 16 of the valve 14 is in engagement with a resilient fork 17 pivotally connected with the diaphragm at 18 and also in engagement with a plate 11 rigid with the plunger 10. In operation, prior to landing, the piston rod is fully extended as shown, and the plate 11 acts on the fork 17 to maintain the valve 14 closed against the action of the spring 15. After the landing im-  pact, the resilience of the fork 17 serves to maintain the valve 14 closed until sufficient pressure is built up in the chamber 7. Liquid is displaced through the grooves 12 into the chamber 8 when the landing impact has been absorbed, and pressure in chambers 7, 8 is then equalized. The valve 14 then opens and remains open thereafter until subsequent total extension of the shock absorber (as on take-off). Damping action during taxying is now provided on extension by a restricted orifice 5 in the piston and on compression by a duct 6 of relatively large cross-section in conjunction with a valve 6a. The braking and valve 6a is proportional to the speed action due to the grooves 12 and the orifice 5 is proportional to the square of the speed of the piston while that due to the duct 6 of the piston. Grooves may be formed in the cylinder wall to provide a damping action.

In a rake-wheel haymaking machine of the type having tines which are cranked in relation to the direction of motion, the orientation of the tines can be reversed by turning them about pivotal axes, either individually or severally, when the direction of rotation of the rake wheel is to be reversed. In Fig. 9, each tine 74 has an inward prolongation 90, beyond therim 73 which is supported by spokes 72 connecting it to a hub 71. The hub is hollow and has an inner convex sleeve 77, the prolongations passing through slots 84 in the hub and having cranked ends which rest against the sleeve 77 either along its lower circle of contact 93 with the hub or its upper circle 97, the orientation of each tine 74 to a tangential direction being equal and opposite in the two positions. In Fig. 13, the rim III and hub 110 are not coplanar and the tines 112 are prolonged inwardly at 122 to pass through a flange 119 and enter, by their cranked ends into holes in a relatively movable sleeve 129. Movement of the sleeve adjusts all the tines simultaneously. In Fig. 15, each tine 152 has an inward prolongation 153 within the rim 151 constituting a spoke and terminating within a hub 150 after passing freely through a hole 154. Each spokeportion 153 has a loop 155, all the loops resting upon one another, so that reversal of the direction of motion of the wheel turns all the tines about the axes of the spokes 153. The rake-wheels may be applied to the machine forming the subject of Specification 924,271.

The ends of a tubular glass member and a tubular aluminium member are sealed together by shaping one end of an aluminium tube 4 to form'a thin-walled cone 5 and seating this on a corresponding conically shaped part 3 of a block i of refractory, heat-conductive material, applying a tubular member 6 of soft glass over or within the metal cone 5 and away from the end thereof so as to press the metal against the block, heating the block i so that the end t of the glass tube is softened to cause it to seal to the metal cone, and establishing a pressure difference between the inside and outside of the glass tube so that the softened end thereof is forced towards the metal cone and the area of sealing contact between the parts is progressively increased. In the arrangement shown, compressed air is introduced into the tubes through pipe 8 so that the end i of the glass tube is blown outwardly to seal against the interior of the cone. In an alternative arrangement the aluminium cone is formed by inwardly tapering the end of a tube whose other end fits over a conically terminated boss on the block, the glass tube then fitting over the cone and the pressure difference being obtained by evacuating the interior of the glass tube to cause it to collapse on to the cone. The wall of the cone may be tapered to a feather edge.. The temperature of the block i may be measured by a thermocouple 9, which is used for controlling the burners heating the block,

Title: Nuclear fuel and/or fertile elements and operation of a nuclear reac-or
IPC: G21C3/62
Filed: 1973-04-02
Abstract: 1431852 Nuclear fuel KERNFORSCHUNGSANLAGE JULICH GmbH 2 April 1973 [1 April 1972] 15715/73 Heading G6C Nuclear fuel and/or fertile material comprises coated particles of a mixture of a fissile or fertile metal oxide and a fissile or fertile metal carbide, for example mixtures of oxides and carbides of U, U-Th, or U-Pu. The proportion of carbide in the mixture (e.g. 3-20%) is such that during burn-up sufficient carbide remains to react with the oxygen produced from the oxide. The invention reduces the disadvantageous formation of CO by reaction of this oxygen with the carbon in the particle coating, which may be pyrolytic carbon and/or silicon carbide. The fuel may be made by hydrolysing and peptizing a nuclear fuel oxide to form a sol, mixing the sol with carbon black, forming spherical gel particles, sintering in a reducing atmosphere, and then coating the particles. Alternatively, the oxide powder may be mixed with powdered carbon or graphite and a binder, e.g. aluminium stearate, and formed into spherical particles which are sintered and coated. A layer containing oxide but no carbide may be provided between the core and the coating. Fuel elements may be formed by introducing the particles into a metal or graphite casing or into a graphite matrix, and are suitable for use in a high temperature or fast breeder reactor.

Title: Production of activated carbon from waste tyres
IPC: C01B31/08
Filed: 1973-04-02
Abstract: 1423440 Active carbon from waste tyres Y SANGA 2 April 1973 [6 Dec 1972 11 Dec 1972] 15725/73 Heading C1A Activated carbon is produced by cutting waste tyres into pieces; mixing with the cut tyre a material which, at a given temperature, pyrolytically yields carbon dioxide gas; heating the mixture in the absence of air to a temperature which is lower than the given temperature, to substantially completely carbonize the cut pieces; then further heating the carbonized mixture to at least the said given temperature so as to pyrolytically produce carbon dioxide gas which serves to activate the carbon produced in the carbonizing step; and the active carbon so produced is separated from the mix. The mixture is preferably cooled before separating the active carbon. This process may be carried out by placing the mixture of cut tyre pieces and decomposable material in a reaction chamber, heating the mix in the absence of air to a carbonizing temperature using a combustion furnace associated with the chamber so as to completely carbonize the cut pieces, and during the carbonizing step feeding the decomposition gases produced back to the combustion furnace via a conduit, further heating the carbonized mix to decompose the added material to give carbon dioxide, and during the subsequent activation step feeding the resulting gas from the activating step back to the combustion chamber, and feeding the carbon dioxide containing gases from the combustion chamber to the activating step via a connecting conduit. The resulting mix is then cooled and the desired active carbon separated. The material added is preferably limestone and the tyre and limestone are preferably mixed in a weight ratio of 1: 1 to 1:2. The temperature of carbonization may be 800‹ C. and the activating temperature above 825‹ C., e.g. between 900‹ and 1000‹ C. The separation step may be achieved using air elutriation.

Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B73/12
Filed: 1934-05-28
Abstract: 416,346. Sewing-machines. HUGHES, R. M., 72, Cannon Street, London.-(International Button Hole Sewing Machine Co.; 502, Harrison Avenue, Boston, U.S.A.) May 28, 1934, No. 15804. [Class 112.] In a buttonhole sewing- machine in which the stitch-forming and workholding means have different relative positions during the sewing and cutting of the buttonhole slot, these means occupy still another relative position, between the two previously mentioned ones, when the machine is brought to rest, such final position ensuring that the work is not snagged on the needle during removal. When the stitching on the buttonhole is completed, the positions of the stitch frame 1 gives the needle a position indicated by the dotted line b of Fig. 1. The shift of the stitch frame from stitching position to buttonhole cutting position will carry the needle from the dotted line relative position b to the dotted line position a. In usual machines of this kind, the stitch frame then moves to give the needle the relative position g for the stopping position so that the needle is in advance of the work clamps 2, the removal of the work 4 from the opened clamps then requiring care to prevent snagging on the needle. In the present invention, instead of moving from g to a on stopping, the needle stitch frame is started on its return journey and the needle 6 assumes as the stopping position, the position shown in full lines. This movement is obtained partly through the shape of the cam groove 14 in the main cam 12 which operates the stitch frame, and partly through a clutch-disengaging cam carried by the clutch controlling lever 22. The clutch-disengaging cam disconnects a pulley 19 from the shaft 18 at the proper time in the reverse journey from the buttonhole cutting position towards stitching position and comprises a cam 44 with a limited movement between shoulders 46, 47 and a stop pin 48.
