Patent GB-301413-A (GB)
Title: Improvements in or relating to the storage and handling of powdered fuel and to the potection of bunkers or like storage apparatus against spontaneous combustion
IPC: B65D90/44
Filed: 1927-06-25
Abstract: 301,413. Brand, J. J. C., and Laing, B. June 25, 1927. Divided on 303,422. Pneumatic conveyers.-Consists in a method of filling a ship's bunker or other storage compartment with powdered fuel, such as coal, and in a method of subsequently discharging the fuel from the bunker &c. whereby spontaneous combustion or explosion is prevented. Inert gas, such as flue or combustion gas, is circulated through the bunker &c., to displace the air and powdered fuel is then blown into the bunker &c. through a pipe line by means of inert gas. Gases of combustion may be withdrawn from a flue &c. or from an internal combustion engine, and after being cooled and dried may be used for circulation through the bunker. For blowing the powdered fuel from, say, a grinding and drying station on shore into the bunkers of a ship, flue or combustion gases are preferably cooled and compressed, e.g. to a pressure of 40 lbs. per square inch. When the bunker has been loaded with fuel, a further supply of inert gas may be admitted to displace air that has leaked in during the filling operation; during discharging, inert gas is allowed to take the place of the withdrawn fuel. For the unloading operation, there may be used one or more pipes extending through the bunker &c. and having one or more valve controlled ports therein, one end of the pipe or pipes communicating with a suction fan and the other being connected to a supply of inert gas. The fan is adapted to discharge to a dust separator, excess gas from the separator being preferably returned to the bunker or the like, while the powdered fuel passes from the separator to a " ready-use " bin. Before withdrawing the fuel from the bunker, its fluidity is enhanced by the method of injecting inert gas through it described in Specification 281,098; cooled and compressed flue gases may be led into the bunker at a number of places for this purpose.

Title: Improvements in or relating to vehicle spring suspensions
IPC: B60G11/23
Filed: 1950-12-06
Abstract: 684,885. Road-vehicle spring-suspensions; adjusting height of body; springs. GOODRICH CO., B. F. Dec. 6, 1950 [Dec. 7, 1949], No. 29862/50. Classes 108 (ii) and 108 (iii). A vehicle suspension comprises a wheelsupporting structure 11 having generally vertical movement in a determinate path A relative to a supported structure 12, an arm 29 pivotally connected to the structure by at least one rubber torsion suspension spring, the rubber, being stressed in torsional shear stress and compression stress, due to the rubber accomodating the difference between the path A of the structure 11 and the path C of the end of the arm 29. Spaced brackets 14, rigid with the chassis frame 12, have stud portions 17 which form a bearing for a tube 18. A rubber sleeve 21 is bonded between the tube 18 and an outer tube 22 mounted in the boss 25 of the arm 29. The boss 25 has overlapping edges at 26, and is formed with a shoulder 28 which engages within a split formed in the tube 22 to prevent relative rotation of the tube 22 and boss 25. The outer rigid bush 32 of a rubber bushing 36 is split at 33, 34 and is secured by bolts 38 to a boss 31 on the outer end of the arm 29. The inner rigid bush 35 of the bushing 36 is secured by a bolt 39 to trunnions 41 rigid with the outer end of an axle 11. Projections (Fig. 2) formed on the trunnions 41 extend axially and inwardly to engage diametrically disposed slots 44 formed in the end faces of the bush 35. Additional pairs of slots 44 may be provided for the purpose of adjusting the preload of the bushing 36. The preload of the bushing 21 is adjusted by rotation of a screw 47 carried by an arm 46 rigid with the tube 18. The line A indicates the path of the bolt 39 due to vertical movement of the axle 11 when connected at each end, as shown, to the chassis 12. The line C indicates the path of the centre of the boss 31 if unconstrained by the connection to the bolt 39. The constraint due to the connection on either side results in a radial compressive stress in the bushing which modifies the spring rate and finally limits deflection. There is a reversal in the direction of this compressive stress between the static-load position of the arm 29 shown in full lines, and the extreme position shown in dot-and-dash lines.

Title: Improvements in or relating to semi-conductive devices
Inventor: JONES ROBERT OWEN
IPC: H01L21/00
Filed: 1958-09-18
Abstract: 904,690. Semi-conductor devices. MULLARD Ltd. Sept. 18, 1958, No. 29893/58. Class 37. A jig for providing alloy junctions on a semiconductor body comprises means for holding the body, a through aperture on one side of the body shaped so as to retain solid alloying material in one position of the jig and such that in a second position of the jig, the material passes into a communicating passage to fall upon one surface of the semi-conductor body. Figs. 1 and 2 show a semi-conductor body 7 located between two carbon members 5 and 6 which slide into channels located in two other members 1 and 2, to form the jig. Apertures 3 and 4 penetrate right through members 1 and 2 and members 5 and 6 have passages 8 and 9 which connect the apertures 3 and 4 to the sides of the semi-conductor wafer 7. Conical depression 10 and 11 in members 1 and 2 and the flared end of passages 8 and 9 serve to retain a pellet 16 of alloy material, when the jig is in a position 90 degrees spaced from that shown in Fig. 1, so that it does not touch the semiconductor body, and grooves 12 and 13 in members 1 and 5 and 14 and 15 in members 2 and 6 serve to prevent the pellet from rolling out of the end of apertures 3 and 4. A plurality of bodies and alloying passages may be provided in one jig. In the alloying process, pellets are first inserted through apertures 3 and 4 into the position shown, then the jig is inserted into a furnace tube and rotated so that the pellets are held in the displaced position and hydrogen passed through at a first temperature, then the jig is rotated 90 degrees to bring the molten pellet into contact with the semi-conductor and alloying proceeds at a second reduced temperature. The jig may then be rotated 180 degrees to repeat the process on the opposite side of the semi-conductor body. In one example a PNP transistor is produced by stoving at the first temperature of 560‹ C. for 20 minutes, then 460‹ C. for 5 minutes for the second temperature and then at a third temperature of 380‹ C. for 5 minutes to provide a low-penetration emitter.

Patent GB-1110133-A (GB)
Title: A separation process
IPC: B01D15/08
Filed: 1965-07-16
Abstract: A separation process which may be used for example to separate aromatic compounds from naphthenic and paraffinic components in a hydrocarbon feed or for separating normal and non-normal hydrocarbons comprises introducing a feed containing "solvent" and "solute" into an adsorption zone containing adsorbent which is selective for the solute and carries adsorbed solvent, and collecting an adsorption effluent lean in solute; flowing a displacing agent into the zone and collecting a desorption effluent containing desorbed solvent and solute; and introducing a portion of the adsorption effluent into the zone in the same direction of flow as the displacing agent and collecting the displaced displacing agent and a product rich in solute.  The examples relate to separation of hexane and benzene at 650 DEG  F. and 1 atmos. pressure on 10X molecular sieve using ammonia as displacing agent.  Generally there may be used the A and X series of sieves, for example <PICT:1110133/C4-C5/1> the 5A and 13X sieves, and the displacing agent is preferably a compound NR1R2R3 where R1R2, R3 are hydrogen or C1-C5 alkyl radicals: CO, NO, SO2, CO2, C1-C5 alcohols, glycols, methyl and ethyl chloride, methyl fluoride or nitromethane. In the two bed process of Fig. 2, feed entering at 101 is heated in 102 and passes into bed 107.  The first cut of adsorption effluent which is solvent-rich is collected in 114. The second cut passes through valve 113 to bed 108 for the second desorption step in this bed. In the first desorption step in bed 108 displacing agent from 115 is passed to the bed through line 119; the material displaced from the bed is recycled to feed by line 129. During the second desorption step in bed 108 the effluent passes to 130; the separated displacing agent is returned from 130 to storage at 115 and a solute-rich stream recovered at 132. Figs. 1 ad 3 (not shown) relate respectively to a single-bed and a three-bed process; Fig. 4 (not shown) to a moving bed process.
