Abstract: 735,793. Batteries. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. April 13, 1953 [May 5, 1952], No. 10060/53. Addition to 704,461. Class 53. A negative electrode for an alkaline accumulator consists of a mixture of finely divided copper and pulverulent iron or iron oxide compressed in the cold state, the iron or its oxide' being obtained by the reduction of ferric oxide and having a density between 0.5 and 1. The ferric oxide may be produced by roasting an iron salt for example the sulphate, oxalate, formate, carbonate, nitrate or chloride. Finely divided iron having the required density can be obtained by dissolving iron in sulphuric acid, roasting at a low temperature the sulphate so formed to convert it into ferric oxide and reducing this by hydrogen at a low temperature to prevent crystallization and sintering of the ron. Other methods of producing ferric oxide may be used for example by heating a mixture of ferrous sulphate and sodium carbonate. Instead of iron, finely-divided magnetite may be used which may be prepared by reducing ferric oxide obtained by heating an iron salt.

Abstract: 955,480. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. May 9, 1962 [March 20, 1961], No. 10072/61. Drawings to Specification. Heading H4K. At least some of a number of exchanges forming a telecommunication system can act as transit exchanges, so that a connection between a first exchange and a second exchange can be established via any one of a plurality of different routes, and means is provided for transferring an existing connection to a different one of the routes from that over which it has been established, the transfer being effected when a certain predetermined condition or one of a plurality of predetermined conditions exists and with substantially no interruption of the communication between the connected parties. In the embodiment described, preference is given to the use of the more direct routes, which are reached by long-distance (e.g. inter-continental) calls via level 2 of a selection stage and by shortdistance calls via level 1. When all the more direct routes are busy, a subsequent shortdistance call is set up over a less direct route via level 9, but the arrival of a long-distance call initiates a search for a more direct route occupied by a short-distance call, the setting up of a parallel connection over a less direct route seized via level O, and the transference of the shortdistance call to this less direct route (preferably during a pause in speech), freeing the more direct route for the long-distance call.

Patent GB-695997-A (GB)
Title: Improvements in or relating to lubricating grease composition
Filed: 1951-05-01
Abstract: A grease composition comprises a mineral lubricating oil, a calcium fatty acid soap and from 0.5 to 5 per cent by weight of a water-soluble, oil-insoluble derivative of cellulose.  The cellulose derivative raises the dropping point of the grease and also the temperature at which syneresis occurs.  Suitable cellulose derivatives include methyl, ethyl, hydroxyethyl, propyl and carboxymethyl cellulose, and the preferred content is about 2 per cent by weight.  The mineral oil may have a viscosity of 40 to 70 S.S.U., particularly 55 S.S.U., at 210 DEG F.  The calcium soap may be prepared from hydrogenated fish oil acids, stearic acid, oleic acid, hydroxystearic acid, beef fat, tallow and saturated or unsaturated glycerides of various fatty acids. Such saponifiable material may be saponified directly with Ca(OH)2 or CaO, and this can be done after the fatty material has been mixed with the mineral oil and cellulose derivative.  Further mineral oil may be added after saponification to give the desired composition.  Alternatively a preformed calcium soap may be used.  The greases usually contain from 10 to 50 per cent by weight of the calcium soap, and preferably from 15 to 25 per cent.  Minor proportions of acidic materials such as sulphuric, ethane sulphonic or acetic acid may also be included. Examples are given.

Abstract: 587,164. Resiliently mounting tanks on vehicles. BUTTERFIELD, Ltd., W. P., and MOSBY, G. P. May 26, 1944, Nos. 10286/44 and 11595/45. [Classes 108 (ii) and 108 (iii)] A tank 2 is supported on a vehicle chassis 3, or bearers thereon, by means of a number of resilient mountings each comprising a rubber block 4 to which upper and lower metal plates 5, 6 are bonded for securing the mounting to the tank and chassis members respectively the block normally being substantially wholly under compression within a housing 11 which permits restricted deformation of the block when under load and when submitted to shear stresses caused by lateral and longitudinal movements of the tank. As shown, bolts 7, the heads of which are bonded to the rubber, project through each plate and secure the mounting to a lower channel-section bearer 8 fixed to the chassis and to the housing 11 which has side clearance to allow for the deformation of the rubber. Shearing action on the bolts 7 is prevented by side flanges 10 on the plate 6 closely fitting the bearer 8 and by a projecting part 12 on the plate 5 engaging a recess in the' housing 11. When the block 4 is excessively compressed, flanges 13 on the housing are adapted to engage a rubber snubbing ring 20 which is bonded to a fixing plate 21 secured to the base 9 of the bearer 8. To allow greater flexibility in the mounting, the side walls of the block may be recessed and the block may be composed of different grades of rubber, have a different core, or be of laminated construction. The tank 2 is shown mounted on a rubber pad or pads 17 on a transverse bolster 14 of inverted V-section which bridges a pair of transversely-spaced mountings and is secured to the flanges 13 on the two housings 11, the tank being held in position by adjustable straps 18 secured by bolts 19 to the bolster. Instead of a bolster, the mountings may be associated with tank feet, rests, or other supports.
