Title: Improvements relating to fuel cells
Inventor: BACON FRANCIS THOMAS
IPC: H01M8/06
Filed: 1961-12-29
Abstract: 984,369. Fuel cells. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 17, 1962 [Dec. 29, 1961], No. 46663/61. Drawings to Specification. Heading H1B. A hydrogen electrode has a layer of porous nickel, the pores containing sufficient palladium or palladium alloy to present an almost complete barrier to the passage of impurities in the hydrogen fed thereto. The layer is preferably sufficiently pervious to allow the passage of water therethrough as steam and the hydrogen is circulated through a water remover and a purifier to prevent the impurities from building up as hydrogen is consumed. The porous nickel layer may be backed by a coaster layer to prevent electrolyte flooding. Specifications 667,298 and 952,206 are referred to.

Abstract: 1,013,173. Dispenser for paper clips. BURGESS VIBROCRAFTERS Inc. Dec. 18, 1962, No. 47738/62. Heading B8S. A clip dispenser for dispensing paper clips 30 one by one, includes a base A, a magazine B which is pivoted to the base at 10, a spring- impelled pusher 28 which is mounted within magazine B, and a cover C pivoted to magazine B and furnished with a hole 19a through which each clip is individually discharged upwards. Holder D, Fig. 3. Clips from the clip-making machine are fed on to holder D which is provided with a resilient member 39 so that stop member 40 thereon serves to retain the clips on the holder. Operation of feeding clips into magazine B.-Holder D full of clips 30 is pressed against pusher 28 to force the pusher backwards against spring 29 so that the clips 30 are gradually forced along rod 26 till the end clip of holder D is able to lodge against the inturned ends 23, 24 of magazine B. Holder D is then withdrawn through the gap between ends 23 and 24, which withdrawing serves to strip the clips from holder D and to retain them in magazine B. The magazine is thus charged and when cover C is pressed downwards it serves to move magazine B against fixed lip 19 which works within the gap between ends 23 and 24 and pushes upwards the end clip through gap 19a in cover C to present the clip for use.

The elastomer preferably has a molecular weight of 800 to 2000 and its concentration in the spinning solution is normally from 5-30% by weight. Further baths may also contain the above coagulating agents. Preferably the fibre is drawn whilst it still contains the solvent. Heat setting may be effected after drawing.

Title: A magnetic information storage disc transducing apparatus
IPC: H01B13/02
Filed: 1967-10-24
Abstract: 1,145,034. Magnetic disc magazines and apparatus. NATIONAL CASH REGISTER CO. 24 Oct., 1967 [25 Nov., 1966], No. 48282/67. Heading G5R. When a magnetic storage disc magazine 20 is located in transducing apparatus, its cover 27 is automatically removed (and replaced) upon closing (and opening) of a hood 12 affording access to the apparatus. Magazine.-Three discs 24 and spacers 26 are clamped by bolts 31 between a base 28, carrying an air filter 37 and a pressure plate 114, and an upper ring 40 having a handle 36 containing a catch 32. The catch contains pins 46 spring-urged 48 to enter a groove 58 in the cover 27 and are retracted by depression of a plunger 62, acting on links 54, 56 to which the pins 46 are coupled, as the magazine is placed over a driving hub 76. The spacers 26, and ports 35, 41 in the base 28 allow passage of air from a supply 128 in the apparatus to clean the disc surfaces. Driving assembly.-A belt-driven hollow shaft 72 carries a three-part hub 76 arranged to be expanded to engage the wall of an aperture 29 in the magazine base 28 upon movement of an inverted frustrum (84) (Fig. 4, not shown) fixed to a vertically movable tube (82). Clamps 102, pivoted to the frustrum (84) and inwardly spring-biased (103) are engaged by the head of a rod (94) slidable within the tube (82) to urge the pressure plate 114 downwardly and thereby pads (110) fixed to bolts 108 into frictional engagement with a friction pad (112) carried by the shaft 72. Movement of the frustrum (84) and clamps 102 to their inoperative positions is effected by upward movement of the sleeve (82) and rod (94) against respective springs (88), 96 by a lever 120 coupled to movement of the hood. Operation.-The hood 12 is opened, whereupon a cable 146 rotates a cam 152 counterclockwise to rotate a follower 154 clockwise and thereby lever 120 clockwise via cable 124 to retract the clamps 102 and raise the frustrum (84). The magazine, with cover 27 intact, is placed over the hub 76 whereupon the rod (94), being raised, engages the catch-release plunger 62 to retract the pins 46. As the hood 12 is lowered, the cam 152 rotates clockwise to lower both rod (94) and sleeve (82) to locate and clamp the magazine and, simultaneously, a second cam 130 rotates follower 126 clockwise to rotate a pulley assembly 164 via cable 156. Rotation of the pulley 164 winds up three cables 166 attached to slides 172 movable in grooved pillars 168 and arranged to grip the cover rim 184 to raise the latter clear of the discs to allow a transducer assembly 21 to be swung into operative position. Re-opening the hood 12 reverses the above sequence so that the discs are always protected from dust. A handle 136 may be used to operate the cam mechanism independently of the hood, e.g. during maintenance.

[Also in Division E2] Apparatus for tipping under the action of gravity a grain bin 1 as in the parent Specification 1,051,053 is provided with a capstan arrangement 30 by means of which tipping frame 4 can be returned to the untipped position after tipping. The capstan drum is formed by a shaft 31 and has a flexible nylon strap 33 fixed thereto and wrapped around it. The strap 33 is fixed at its other end to the frame 4. In the untipped position (as shown in full lines) the strap 33 extends directly upwards from the capstan shaft 31 and the capstan 30 runs free as the frame 4 tips. The capstan 30 can be turned by hand to wind up the strap 33 to return the frame 4 and the empty bin 1 to the untipped position. To prevent the bin 1 from tipping off the frame 4 the latter is provided with a front support rail 13.

Title: Hydrocracking process
IPC: C10G47/16
Filed: 1963-12-09
Abstract: High boiling mineral oil feedstocks, e.g. b.p. 300-1000 DEG  F., are hydrocracked to produce lower boiling hydrocarbons, e.g. gasoline, jet fuel and heating oils, by contacting said feedstocks at 400 DEG to 800 DEG  F. and 500 to 2500 p.s.i.g. in presence of added hydrogen with a catalyst comprising (1) a zeolite molecular sieve cracking base of the Y crystal type wherein the zeolitic cations include hydrogen ions and wherein at least 10% of the ion exchange capacity is satisfied by divalent metal ions and (2) a Group VIII metal hydrogenating component intimately compounded with the cracking base. The divalent metals are preferably the metals of Group II, e.g. magnesium, calcium, zinc, beryllium and cadmium or manganese.  The catalysts are prepared by ion-exchanging the sodium zeolite with solutions of ammonium and divalent metal ions either simultaneously or sequentially followed by heating to decompose ammonium ions to hydrogen ions.  The product is then impregnated with the Group VIII metal, e.g. Pd, Pt, Rh, Ru or Ir or alternatively, the Group VIII metal may be incorporated into the catalyst by ion exchange prior to decomposition of the ammonium ions in the zeolite. Preferably the catalyst contains at least 20% of hydrogen ions and less than 3% by weight of Na2O.  The catalyst may be periodically regenerated by combustion with oxygen-containing gases at high temperatures followed by reduction with hydrogen. The presence of water vapour in the cracking process does not cause the catalyst material to deteriorate.ALSO:Hydrocracking processes are carried out in the presence of zeolitic catalysts comprising (1) a zeolitic molecular sieve cracking base of the Y crystal type wherein the zeolitic cations include hydrogen ions and wherein at least 10% of the ion exchange capacity is satisfied by divalent metal ions, and (2) a Group VIII metal hydrogenating component intimately compounded with the cracking base.
