Filed: 1973-11-14
Abstract: 1409215 Lead battery electrode connections GATES RUBBER CO 14 Nov 1973 52883/73 Heading H1B [Also in Division B3] In connecting together lead collector tabs 30 and a lead post 32 of an electric battery cell sub-assembly, the latter is supported in a holder 26 positioned, by guides 24, in a table 12, the tabs 30 and a portion 48 of the post are pushed together by jaws 44, 46 having portions 52, 50 forming mould walls, and the tabs 30 and post portion 48 are fused together using an inert gas-shielded, non-consumable electrode, arc welding torch 18, the arc moving in a sinusoidal or zig-zag path relative to the workpiece, and the mould walls retaining the fused metal and, by heat transfer therethrough, causing solidification from the metal periphery inwards. The cell sub-assembly may comprise parallel plates or, as shown, spirally wound positive and negative lead plates and interleaved porous absorbent separator material, the plates being, e.g., of expanded mesh or foil substrate bearing a bonded layer of electrochemically active lead paste and a plurality of tabs 30, 30<SP>1</SP>. Prior to welding, the tabs and post may be crimped together and cleaned or chemically conditioned. The electrode of the torch 18 is preferably of tungsten or tungsten alloy and the shielding gas may be argon or helium and may have hydrogen or other gas admixed therewith. As shown, the torch is carried by a rectilinearly movable carriage (14). The torch may be transversely oscillatable or the arc may be oscillated magnetically using a non-oscillating head. Preferred oscillating rate is 60-2400 cycles per minute. The head and table may, alternatively, be respectively stationary and movable. The post 32 is positioned by a locator 34 having a pivoted arm 36, an apertured post-receiving portion 38 and, for post retention, a vacuum bonnet connected to a vacuum line 40. After location of the post between one set of tabs 30, the jaws 44, 46 are actuated, e.g. hydraulically or pneumatically, and the locator 34 is then withdrawn, a microswitch actuated by a spring 42 serving to render the welding torch operable only in the fully withdrawn position of the locator. The jaws 44, 46 are of arc-erosionresistant material having adequate electrical and thermal conductivity and a softening point higher than that of lead, such as titanium, tantalum, carbon, steel or copper (water cooled or having a surface layer of tungsten) or preferably tungsten or tungsten alloy (e.g. 2% thorium). One or both of the jaws may serve as a positive or negative counter-electrode. Preferably the current for the torch is relatively high on approach to the workpiece and is reduced for the welding. After welding, the fixture may be turned through 180 degrees in preparation for welding the tabs 30<SP>1</SP> to a post.

Coal is subjected to low temperature carbonization to produce tar oil 3, coal gas 4 and coke 2; the coke is treated in a water gas generator to produce water gas 7 and blow gas which is used to fire the carbonization retorts. The coal gas 4 is reformed with steam over a nickel catalyst at 550‹ C. to produce a hydrogen-carbon monoxide mixture which is subjected to shift conversion followed by scrubbing to remove carbon dioxide and leave the hydrogen stream 9. Part of the stream 9 is used to hydrogenate the tar oil and the remainder is used to increase the hydrogen/carbon monoxide ratio of the water gas prior to Fischer-Tropsch synthesis to produce the fuel oil 16. Hydrogen-carbon monoxide mixture can be added to the water gas or to the reformed gas mixture 8 through a balance connection. Fig. 2 (not shown) illustrates an embodiment in which the coal gas is treated by thermal cracking in a chamber heated by blow gas from the water gas generator to produce the hydrogen stream and a carbon black product.

Abstract: 1526140 Liquid particle separator ATLAS COPCO AB 23 Dec 1976 [23 Dec 1975] 53839/76 Headings BIT B2P An apparatus for separating liquid (e.g. oil) from compressed gas comprises a container separated into two compartments by a non- return valved plate 2, into the upper compartment of which gas is admitted (e.g. tangentially) so that liquid particles are deposited and flow downwardly through opening 6 into lower compartment 70, and partly cleaned gas is then passed through a filter element 8. Gas may then exit through a head piece 13 by way of a pressure check valve 20 and passage 16. On decompression of the upper chamber oil containing compressed gas bubbles is prevented from expanding into the upper chamber by the closure of non return valve piece 4. Oil may be drained from compartment 70 and through tube 9 for reuse. A fine bleed aperture e.g. 32 equalizes pressure slowly.

A tractor seat pan is carried on a swing- ing tubular arm 10, which contains resiliently urged links or gearing to permit vertical oscillation, while holding the seat level. As shown, a crank 15 is connected to the pan for angular movement therewith and is held parallel to fixed crank-14 by pivotally engaged, interconnecting rod 11. Tubular arm 10 is journalled on fixed shaft 20 of crank 14 and has its adjustable end 41 spaced from the end of crank 14 by plate springs 40. The height of the seat may be adjusted by screwing knob 42 to vary the compression of springs 40. A damping arrangement includes piston 43 on rod 11 moving in a liquid filled cylinder 44. The damping arrangement may be replaced by a compressible polymer or a rubber spring. Torsion springs may be used instead of compression springs. In Fig. 7 (not shown) a torsion bar (90) is mounted in a tubular extension (94) of crank shaft 17. In Fig. 8 (not shown), rubber torsion springs (100) are employed. Screw or worm means (92) may be used for pre-stressing these springs. In a modification (Fig. 5, not shown), a telescopic construction of arm 10 and rod 11 allows the distance and angle between the shafts 20 and 17 to be varied. Independent adjustment of the length of rod 11 may be used to vary the fore and aft inclination of the seat pan. In another form (Fig. 6, not shown) pinions (74) replace cranks 14 and 15 and a tubular shaft (72) having meshing bevel gears (73) is resiliently urged by a co-axial torsion spring (75) to support the seat load. Frictional damping is provided by brake (80) and a radial hydraulic damper (79) is employed.

Abstract: 1437351 Embossing IMPERIAL CHEMICAL INDUSTRIES Ltd 26 Oct 1973 [28 Nov 1972] 54805/72 Heading B6J A thermoplastics sheet 13 is supported on an embossing member 12 supported on an air permeable sheet 11 having a metal frame 14 resting on a channel framework 15. A stationary upper plate 1 is provided with a plurality of ducts 9 leading to a source of air pressure or suction, and supports a diaphragm 5, while a vertically movable lower plate 2 is provided with similar ducts 10 and with heating means. Four frameworks 15 form the limbs of a table rotatable in a horizontal plane through four stations. In operation, the member 12 and sheet 13 are loaded on a framework 15 at the first station, the sheet is embossed at the second station, which is between the plates 1, 2, the embossed sheet is cooled at the third and fourth stations, and removed from the member 12 and replaced at the first station. There operations are performed on each of the four frameworks 15. For embossing the sheet, the plate 2 is moved upwards, lifting the assembly 12, 13 11, 14 off the framework 15 and forming an air-tight seal between the plates 1, 2 via the member 12, diaphragm 5 and a silicone rubber gasket 4. Air is evacuated from the upper and lower compartments 7, 8 of the air-tight space, as defined by the diaphragm, and hence from the interface between the member 12 and sheet 13. Air at atmospheric pressure is introduced into the upper compartment, so that the diaphragm forces the sheet 13 tightly against the member 12 and the supporting sheet 11 against the heated plate 2, so that embossing takes place. Air is then introduced into the lower compartment, and the plate 2 is lowered, the assembly 12, 13, 11, 14 coming to rest on the framework 15. The diaphragm is of silicone rubber coated glass fibre. The sheet 11 is of glass fibre fabric, coated with silicone rubber perforated except in the marginal areas to render it permeable, or coated with silicone rubber only in the marginal areas. The member 12 may be an engraved metal plate, or a silicone rubber sheet with a metal or fabric support. The thermoplastic sheet may be of polyvinyl chloride coated fabric, and may consist of two layers one solid and one cellu.ar. It may contain a blowing agent so as to be expanded when heated. Specifications 1,168,273, 1,290,609 1,300,006 and 1,300,007 are referred to.
