Abstract: 638,001. Rope railways. KING, Ltd., G. W., and KING, D. M. Nov. 11, 1946, No. 33508. [Class 104 (ii)] In a rope railway wherein cars are propelled along a track 10 by a driving chain, the chain 11 periodically actuates a track switch 13 or a lift section through an auxiliary endless chain 14 which engages with the main chain 11 in a common guide means 17 and drives a cam 19-20 or eccentric whereby the track switch or lift section is operated through a follower 21 held in engagement with the cam or eccentric. The system shown is one wherein the chain 11 has abutments engaging the cars, and the chain is engaged by projections 15 on the endless auxiliary chain 14 which passes over a sprocket wheel 16 geared to the wheel 19 having the cam or eccentric 20.

Title: Method of handling radio active waste solutions
IPC: G21F7/06
Filed: 1957-10-28
Abstract: 837,967. Treating radioactive waste solutions. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 28, 1957 [Nov. 30, 1956], No. 33510/57. Class 39(4). Radioactive waste aqueous solutions are concentrated by spraying the solution below the surface of a heated fluidised bed of oxides of the cations present in the solution and removing radioactive solid product from the base of the bed. As shown the fluidised bed is maintained at 11 by means of gas introduced at 17 below porous plate 14. Waste solution is sprayed through nozzles 24 and the bed is heated by electric heaters 30. Exhaust gas passes through filters 19 to condenser 23, while radioactive solid is removed at 15. Solutions containing aluminium nitrate, obtained by processing aluminium-uranium nuclear fuel, may be treated at about 500‹C using a bed of aluminium oxide fluidised by steam ; the condensed steam dissolves the nitrogen oxide formed, producing nitric acid.

Filed: 1955-11-23
Abstract: 776,916. Ratchet winches. VHLIG, G. Nov. 23, 1955, No. 33604/55. Class 78 (5). A portable winch comprises cable drum 12, ratchet-wheel 14 secured thereto, and handle 70 which is pivoted at 10 and carries pawl 40 and is reciprocated to drive the drum by engagement of said handle pawl with said ratchet wheel. For permitting load C to fall under its own weight handle pawl 40 is displaceable outwardly to a second position free of ratchet-wheel 14 by means of thumb-wheel 48, movement of the latter displacing spring 44, which spring influences said handle pawl. In said second position, the pawl (upon reciprocation) engages spring 26 which controls frame pawl 18, so that spring 26 simultaneously forces pawl 18 and pawl 40 respectively away and towards the ratchet wheel, which latter thus comes under the control of pawl 40, and load C is then lowered by clockwise rotation of the handle.

Abstract: 514,134. Cellulose ester fibres. BRITISH CELANESE, Ltd. Nov. 21, 1938, No. 33778. Convention date, Nov. 20, 1937. [Class 2 (ii)] Staple fibres of organic esters of cellulose or filaments or yarns thereof for conversion into staple fibres, have their tendency to electrification reduced, and/or their coefficient of friction increased by treating them with saponifying agents for 6 to 14 hours at such a rate that the acidyl content of the material is not reduced by more than 2 per cent. in 8 hours treatment, washing until neutral, and subsequently treating them with an anti-static dressing, preferably that described in Specification 484,858. Saponification agents employed are: an aqueous solution of an alkylolamine, e.g. triethanolamine, non-volatile organic bases such as mono, di, or triamines, tertiary or quaternary substituted aminonias, or aqueous ammonium hydroxide. The filaments or staple fibres whilst still wet after saponification, are immersed in or sprayed with the dressing solution, and finally spun into threads or yarns. In examples: (1) Cellulose acetate fibres are saponified with an aqueous solution of ammonia for 8 hours at 28‹C., washed until neutral, and immersed in an antistatic dressing containing mineral oils, a sulphonated fatty alcohol, and a saturated solution of magnesium chloride. (2) Fibres are 'immersed in an aqueous solution of triethanolamine, withdrawn, centrifuged, and allowed to stand for 6 to 14 hours. Any residual triethanolamine is then washed out, or subsequently neutralized by oleic acid contained in the antistatic solution.

A grid for a lead-acid accumulator is formed of inert plastic material, e.g. polyvinyl chloride, polythene, polystyrene, a phenol formaldehyde condensation resin, a silicone resin or glass silk with a resinous bonding agent loaded with a lead oxide or a mixture of lead oxides to make it electrically conductive. For a grid for a positive plate polyvinyl chloride is loaded with lead dioxide and for a grid for a negative plate it is loaded with so-called " grey lead oxide ". The grid is preferably moulded from a mixture in which the plastic material is 20-40 per cent by volume of the lead oxide or oxides. According to the Provisional Specification the positive grids may be made of compressed lead dioxide and the negative grids may be made of plastic material loaded with lead or carbon in addition to lead oxide.

Title: Improvements in or relating to synchromesh devices

Abstract: 926,311. Positive clutches. REGIE NATIONALE DES USINES RENAULT. Oct. 8, 1959 [Oct. 24, 1958], No. 34137/59. Class 80 (2). Balk-ring friction synchronizing cones 9, 10, Fig. 1, have radially inwardly projecting lugs 11 engaging with lost motion in relatively large axial notches 12 formed in the hubs of pinions 2, 3 constructed with dogs 7, 8 for selective engagement by the internal teeth 20 of an axially slidable ratio establishing sleeve 4, extensions 11<SP>1</SP> of the radial lugs 11 being oblique to the axis of a shaft 1 freely supporting the pinions and springs 14 normally biasing the synchronizing cones to engage the extensions 11<SP>1</SP> lightly in the bases of grooves 13 formed in a hub 5 secured for rotation with the shaft, the sides 18, Fig. 5, of the lugs 11 being bevelled to coact with the similarly bevelled edges 19 of the notches 12 so that when relative rotation occurs between the ratio establishing sleeve 4 and the pinions 2, 3, the reaction force between these bevelled surfaces 18, 19 resists engagement of the clutch teeth and dogs. When the ratio establishing sleeve 4 is first slidden left or right of Fig. 1 from the position shown, an internal frustoconical surface 9<SP>1</SP> in the sleeve engages frictionally with a correspondingly-shaped surface formed around the periphery of the associated synchronizing cone 9, and tends to increase the reaction force between the bevelled edges 18, 19 on the lug 11 and the corners of the slot 12 to balk engagement of the clutch teeth &c. 7, while simultaneously tending to synchronize the speeds of rotation of the two parts. On synchronization, the radial lugs 11 move towards the centres of the notches 12, and the ratio establishing axial sliding movement of the sleeve 4 can be completed to engage its internal teeth 20 with the clutch dogs 7 &c. Each spring 14 is fast at one end 14<SP>1</SP>, Fig. 3, in a notch 17 formed in the hub of the associated pinion 2, 3, and engages the undersides of the oblique extensions 11<SP>1</SP> of the radial lugs 11. When the ratio establishing sleeve 4 is restored to the neutral condition shown in Fig. 1, the spring 14 biases the associated synchronizing cone 9 or 10 away from its pinion 2, 3, so that the bevelled surfaces 18, 19 re-engage as soon as relative rotation occurs between the parts.

Title: Improvements in mounting of solid state electronic components
IPC: H03F3/45
Filed: 1966-07-29
Abstract: 1,097,296. Mounting semi-conductor devices. GENERAL ELECTRIC CO. July 29, 1966 [Aug. 19, 1965], No. 34169/66. Heading H1K. One or more pairs of matched solid-state components are mounted together in such a way as to ensure that the effects of the ambient temperature are the same on each component. As shown matched transistor chips 10, 12 are mounted on a ceramic or glass header 32 to which is bonded a can 36. A lip 37 on the can is gripped between the inwardly projecting lips 44, 46 of a cap 40 and nut 42 of material of high thermal conductivity and is thus held so that the walls of the can and cap are spaced apart to provide thermal insulation. The nut is placed on a printed circuit board 48 to which the transistors are connected (to form the active part of a differential amplifier) and the entire assembly potted in epoxy resin loaded with alumina. Because of its high thermal conductivity the cap and nut assembly rapidly assumes a reasonably uniform temperature in the presence of a temperature differential in the resin on its opposite sides and this together with the high thermal resistance between the outer and inner assemblies ensures that the ambient temperature of the two transistors is the same.
