Title: Hollow-walled sleeve and method of fabrication of said sleeve
IPC: F16L59/14
Filed: 1973-06-22
Abstract: 1421960 Making deformable sleeves COMMISSARIAT A L'ENERGIE ATOMIQUE 22 June 1973 [3 July 1972] 29834/73 Heading B3A [Also in Division F2] A hollow-walled deformable sleeve 2 consists of two co-axial walls 4, 6 joined to each other by two half-tori 8, 10, flutes 12, 15 being formed in each wall 4, 6 with the axis of each flute parallel to the axis of the sleeve 2, the length of each flute being slightly greater than one half the length of the sleeve, the flutes being such as to have their openings alternately on one half tori or the other. The sleeve 2 may be of cylindrical shape as shown, of frusto-conical shape or may have the shape of a frustrum of a sphere. The sleeve may be made of metal, e.g. steel, aluminium and its alloys, or unalloyed copper, or of plastics material, e.g. nylon or polytetrafluoroethylene. In a preferred mode of fabrication the sleeve 2 is formed of four elements, namely a first element consisting of the inner wall 6 and two inner quarter tori 16, 18, a second element constituting the outer wall 4, and third and fourth elements constituting the quarter tori 20 and 22. These four elements are subsequently welded or bonded together to form the sleeve 2. The first element is formed from a rectangular blank by first forming flutes 15 by roller bending, then joining the ends together by welding to form the outer wall 4. The quarter tori 20, 22 are formed by bending annular blanks in a die. The four elements are then joined together by welds 23 to form the sleeve 2. Two inlet nozzles 26, 28 are welded to the half-toris 8 to permit the admission of fluid under pressure. The sleeves 2 may be utilized in the heatinsulation of a duct 30 (Fig. 3). The heat insulating material 32 is surrounded by a series of sleeves 2 (only one of which is shown), the sleeves 2 being placed between the duct 30 and the heat insulating material 32. By injecting fluid under pressure through inlets 26, 28 the sleeve makes it possible to apply a prestress to the heat insulation 32 while ensuring longitudinal leaktightness of the installation. The sleeves 2 can also be applied to the prestressing of cylindrical concrete pressure vessels or slabs by interposing a sleeve 2 between the concrete and a peripheral restraint or external hoop constituted by a metallic strip wound in one or a number of thicknesses either in a simple or crossed helix without initial tension. In this way a uniform prestress is applied at the time of pressurization of the sleeve 2.

Title: Process for the manufacture of sodium carbonate
IPC: C01D7/07
Filed: 1963-07-29
Abstract: <PICT:0994601/C1/1> Sodium carbonate is manufactured from solutions of caustic soda containing sodium chloride in a process wherein the caustic soda solutions are carbonated in an ammonia-soda process together with the ammoniacal brines of the ammonia-soda process, the precipitated sodium bicarbonate being separated and heated in a known way to give sodium carbonate.  The caustic soda solutions containing sodium chloride may be those obtained by electrolysis of sodium chloride solutions in diaphragm cells. In the combined process of the Figure, brine is divided into two streams flowing one to the electrolysis cells 1 and the other to washing tower 2 (wherein the initial solution may be precarbonated by means of the residual falls from the ammonia-soda process), ammoniating tower 3 and carbonating tower 4 which receives carbon dioxide from calciner 6. The carbonation is carried out in the presence of an amount of ammonia greater than that used in the normal ammonia-soda process, i.e. greater than about 85 gms. ammonia per litre of sodium chloride brine.

Title: Apparatus for coupling television cameras and receivers
IPC: H01P1/12
Filed: 1960-08-31
Abstract: 894,238. Television distribution systems. SIEMENS & HALSKE A.G. Aug. 31, 1960 [Sept. 2, 1959], No. 29951/60. Class 40 (4). In a circuit for connecting a plurality of television cameras E1, E2, with a plurality of receivers A1, A2 in any combination, by means of relay contacts, the cameras and receivers are connected to twin feeders L1 . . . L4, one of the legs of each feeder being earthed to the chassis, the arrangements being such that there are the only break contacts in a circuit connecting any camera to any receiver are shunted by the earth connections via the chassis. The feeders L1, L2 are normally terminated by resistances Z1 Z2. On operation, say, of contacts kh12 for connecting E1 to A2 the make contact connects the " hot " sides of the two circuits together, and the change-over contact disconnects Z1 and connects the "cold " sides of the circuits. The only break contact in the circuit is thus that of kh11 which is shunted by the chassis connections. This arrangement minimizes the chances of poor transmission by reducing the number of contacts involved. A further terminal A3 for connecting a plurality of receivers in parallel is provided with an amplifier which is normally disabled by a biasing voltage U if both k1 and k2 are back. Variable capacitors C are provided to compensate for the mismatch in connecting coaxial inputs E1 to the twin feeders.

Title: Improvements in and relating to steering arrangements for multi-axle trailers
IPC: B62D13/04
Filed: 1947-11-12
Abstract: 651,473. Steering trailers. SOC. ANON. A. SAURER. Nov. 12, 1947, No. 30110. Convention date, Feb. 16, 1945. [Classes 79 (iii) and 79 (v)] [Also in Group XXXII] In a steering arrangement for a trailer in a tractor-trailer combination the wheels of the front axle are mounted for castor action during forward movement and the wheels of the other axle are steered through a coupling member connected to a member on the tractor. As shown in Fig. 1 wheels of the rear axle 7 of the trailer 4 are steered by the variation in the longitudinal axes of the tractor 1 and the trailer through a rod 19 pivoted at one end to the tractor and at the other to a lever 17 pivoted on a pin 18 on the trailer, which lever is connected to a bell crank lever 15 by the coupling member 16, the bell crank lever 15 actuating a divided track rod 14 connected by steering arms 12, 13 to wheels 11, 10. The front axle 6 carries by steering pins wheels 8, 9 which are interconnected by steering arms 22, 23 and a track rod 24. The angle of the steering pins can be varied in a vertical plane to provide castor action for either forward or rearward travel by rotation of an arm 26 on the axle 6. Rotation of the arm 26 is effected by a spring urged piston 32 in a cylinder 33 pivoted on the trailer frame. The piston rod 31 is connected to toggle links 27, 28 so that the spring 35 urges the rod 31 against a stop 38 turning the steering pins on the axle 6 to the position shown in Fig. 2 for forward travel. When fluid pressure is passed into the cylinder 33 through a pipe 37 the piston 32 is urged to the right compressing the spring 35 and turning the axle anti-clockwise to give the wheels castor for rearward travel. The fluid pressure is controlled by a valve actuated by the change speed lever of the tractor or by the rotation of the propeller shaft. In a modification, Figs. 4 and 5, when the tractor and trailer are travelling rearwardly the axle 6 can be positively steered by a lever 42 being rotatively mounted but not axially displaceable on the pin 18 and connected to a bellcrank lever 44 actuating the track rod 24. The lever 17 is moved axially on the pin 18 by a piston 50 in a cylinder 52 operating a lever 45 so that a claw 46 on the lever 17 engages a depression 47 on the lever 42 and the wheels 8, 9 are positively steered by variation of the angle between the longitudinal axes of the tractor and trailer. The piston 50 is actuated by fluid pressure controlled in the same manner as that for the cylinder 33.
