Abstract: 1,144,118. Preparation of thiourea dioxide. FMC CORP. 27 Sept., 1967, No. 43984/67. Heading C2C. A continuous process for the production of amino-imino-methane-sulphinic acid (thiourea dioxide), comprises continuously feeding an aqueous solution of thiourea containing from 0À7 to 10% by weight of thiourea to a reaction zone, concurrently continuously feeding an aqueous solution of hydrogen peroxide into the reaction zone and producing an intimate mixture of these reactants, the amount of H 2 O 2  thus introduced being such as to produce a reaction mixture containing from 1À5-12% by weight of H 2 O 2  and the hydrogen peroxide and thiourea being reacted in approximately stoichiometric proportions, continuously withdrawing reaction mixture from the reaction zone, maintaining the reaction zone at a temperature within the range of from 5-80 C., controlling the rate of flow of the aqueous solution of thiourea and the stream of H 2 O 2  and the rate of withdrawal of the reaction mixture from the reaction zone so that the residence time of the reactants and the reaction product in the reaction zone is within the range 0À1 1 sec.- 10 mins., and the pH of the reaction mixture is from 3-7, cooling the reaction mixture immediately upon withdrawal from the reaction zone thus forming a slurry of amino-iminomethane sulphinic acid crystals, and continuously separating the amino-iminomethanesulphinic acid crystals from the slurry.

Title: Submersible housings
IPC: H02G15/14
Filed: 1971-09-23
Abstract: 1364112 Repeater housings STANDARD TELEPHONES & CABLES Ltd 23 Sept 1971 44387/71 Heading H2E A housing for a submarine cable repeater is generally similar to known housings in having a cylindrical outer casing 1 closed at the end by a bulkhead 2 which is clamped by a threaded ring 8 on to a sealing ring 5 of lead, and in having two 0-rings 9 in grooves 21 with between them petroleum jelly which is pressurized by adjustment of a screw 19 driving a piston 17 in a cylinder 10. The present invention is distinguished by particular choice of dimensions. The outer casing 1, in the region adjacent the 0-rings 9, is ¢-¥ inch thick. The gap between the casing 1 and the bulkhead 2 in this region is ¢-3 thousandths of an inch. At atmospheric pressure and 22C the jelly is pressurized to 2-4À5 tons/ in.2. These dimensions are stated to produce two results. Firstly, when the housing is transported through the tropics, at temperatures up to 45‹ C., the casing 1 flexes in a controlled fashion so that the jelly pressure does not rise too far. Secondly, when the housing is lowered to the sea bed, the water pressure causes the casing 1 to flex in a controlled fashion so as to compress the jelly and increase its pressure without the need for a separate intensifier.

Abstract: 1,135,934. Pressure-relieving devices. MINISTER OF TECHNOLOGY. 2 Nov., 1966 [25 Oct., 1965], No. 45033/65. Heading F2V. Bursting of the membrane 4 at a particular pressure is initiated by a spark discharge from an electrode 8 which punctures the membrane. The discharge is set up from a switching spark gap by a triggering voltage in known manner, Fig. 2 (not shown), in response to the desired bursting pressure in the vessel 2. The discharge is confined by a passage 13 in an insulating disc 11 positioned by an insulating bush 12 on the membrane. Where the membrane is non- metallic, an earthed metal foil is interposed beneath the insulator 11. In a modification two membranes are arranged on opposite sides of an intermediate chamber filled with water. The electrode 8 is associated with that membrane remote from the pressure vessel. Rupture of that membrane nearer to the vessel is initiated by a shock wave transmitted through the water following rupture of the first membrane by the spark discharge. The hole 13 in the insulator may be occupied by a thin fusible copper wire embedded in a cold setting resin, to provide an initial conducting path.

Title: Improvements in or relating to transverse-flow blowers
IPC: F04D17/04
Filed: 1962-11-29
Abstract: 1,020,871. Transverse-flow blowers. R. COESTER. Nov. 29, 1962 [Nov. 29, 1961], No. 45204/62. Heading F1C. In the transverse-flow blower shown, air is bled from the discharge diffuser 6 through a duct 9 and returned to the suction chamber 2 at an opening 9<SP>1</SP> located upstream of the point 10 at which the rotor 1 enters the suction chamber, for the purpose of stabilizing the characteristics of the blower and improving its efficiency. This supplementary stream, which flows approximately tangentially to the walls 11, 12, mixes with the incoming air in the suction chamber whereby abrupt changes of flow velocity in the rotor (and resultant noise) are avoided. The air bled from the diffuser 6 is taken particularly from the energy-depleted zone along the wall of the diffuser, and consequently the pressure conversion in the diffuser is improved. Some air returns from the highpressure chamber 3 through a gap 13 between the rotor 1 and a wall 14 and is deflected by the wall towards the rotor periphery shortly before reaching the point 10, the flow through the gap producing vortices W 1 , W 2 . A duct 17 may be provided to supply air from the duct 9 to the gap 13 to compensate for frictional losses occurring in the gap. Air returned from the chamber 3 to the chamber 2 through a duct 7 renders the velocity distribution more uniform.

Abstract: 1331756 Fluid actuators TRISH ENERGETICS INC 29 Sept 1970 [20 Oct 1969] 46245/70 Heading F1D A fluid actuator 10 comprises a flexible, hollow thin-walled shell 12 defining a fluid chamber 14, and coupling members 16 attached to each end of the shell 12 which serve as inlet, outlet or exhaust passageways. A circumferentially spaced series of non-stretch strands 32 extend axially between the members 16 and are bonded to the shell 12 to prevent axial extension thereof. A single non-stretch strand is wound in a helix round the shell 12 to form circumferential strands 34 also bonded to the shell 12. Initially, Fig. 3, the shell is star-shaped in cross-section, the strands 32 being parallel to the shell axis. When fluid pressure is introduced, although the surface area of the shell remains constant, the shape of the shell will change into an oblate spheroid, Figs. 3 and 4. During such a change the strands 32 bend thus bringing member 16 together. On release of pressure from the chamber 14 the shell will assume its original shape. The actuator 10 can be used in a reciprocating motor or to provide the rotary output motion or even in an electrical control switch, Figs.6, 7 and 8, (not shown).
