Abstract: 1480604 Valves VDO SCHINDLING AG 8 Nov 1974 [9 Nov 1973] 48474/74 Heading F2V [Also in Division G3] A pneumatic valve, for use in a vehicle engine speed regulating system (see Division G3) comprises a solenoid actuated by the vehicle speed error. For underspeed conditions, the energization of solenoid 16 is increased to cause valve member 30 to move from its seat 24<SP>1</SP>, thus allowing air under vacuum from the engine manifold to pass to an engine throttle control bellows (not shown). Similarly, for engine overspeed, the solenoid energization is reduced and valve assembly 15 rises against the action of spring 33 to maintain valve member and seat 30, 24<SP>1</SP> in contact but moving valve member 31 from seating 32. This allows air at atmospheric pressure to pass to the bellows to increase the engine speed. In an alternative construction (Fig. 3, not shown) the valve assembly forms an integral part of the bellows and is actuated by a solenoid with an externally hinged armature.

Title: Method of manufacturing spherical particles
IPC: B01J2/06
Filed: 1971-10-19
Abstract: 1317388 Making spherical particles BELGONUCLEAIRE SA 19 Oct 1971 [20 Oct 1970 (2)] 48584/71 Heading B5A [Also in Division C1] Spherical particles, especially nuclear fuel particles, are made by projecting a stream of gas which carries liquid droplets on to the surface of a bath at an acute angle thereto, the bath containing a liquid which will cause the droplets to solidify, or to form pellicles. Preferably the bath 7 has a thin surface covering 10 of a further liquid which is inert and has a desnity only slightly lower than that of the main liquid 11; the gas stream issuing from a nozzle 4 produces a wave 8 on the surface of this inert layer and the droplets roll down it to acquire spherical form before entering the liquid of the bath which preferably contains a reagent which will result in the formation of a solid precipitate. For nuclear fuel the droplets are formed from a solution or dispersion of salts of uranium, plutonium, thorium or other transuranian elements. In an example a solution of uranylnitrate is prepared from butylglycol and methylcellulose and an aqueous solution of this with nitric acid is fed through an injector 2 fitted with a stop-valve 3, a gas stream, e.g. of air, nitrogen or argon, being supplied through the outer tube 4 and the angle to the horizontal 6 being less than 45 degrees and preferably between 25 and 35 degrees. The bath contains a layer 10 of amyl alcohol floating on liquid ammonia 11 in a cylindrical bath and the droplets are projected tangentially to the peripheral rim. The droplets form into pellicles as they fall through the liquid ammonia and the reaction then continues until they are transformed into ammonium-diuranate particles which are filtered, dried and sintered in a reducing atmosphere to uranium dioxide. Suitable quantities and dimensions are given for the components. The inert liquid may be other organic alcohols or compounds such as benzene, xylene or heptane.

Abstract: 985,545. Dishwashing machines. GENERAL ELECTRIC CO. Dec. 10, 1963 [Dec. 31, 1962], No. 48637/63. Heading A4F. Apparatus for dispensing detergent into a dishwashing machine comprises a container 23 intermittently rotatable to discharge material sequentially from two pockets 35.1, 35.2 therein and a shield 36 covering the pockets to prevent moisture entering thereinto during a dishwashing operation and to retain the material in one pocket while the other is discharging. The dishwashing machine is provided with an electric control system, and the rotation of the container 23 is regulated by an escapement wheel 25 which is rotated 90 degrees counterclockwise (as seen in Fig. 5) by a spring 43 during admission of water for the first wash when a bimetal strip 58 is electrically heated and flexes to disengage a finger 56 from a tooth 53 on an inner part 47 of the wheel 25, to discharge detergent from the pocket 35.1, the rotation being halted by the engagement of the finger 56 with a tooth 50 inside the wheel rim. Immediately after commencement of the first wash the bi-metal circuit is broken, and the finger 56 releases the tooth 50 and comes into the path of a tooth 54 to halt the escapement wheel after about a 30 degrees rotation, to shake loose any detergent remaining in the pocket 35.1. After drainage of the used washing liquid a second wash is initiated and the bi-metal strip 58 is again heated so that the finger 56 disengages from the tooth 54 and comes into the path of a tooth 51, whereby the container 23 rotates through about 60 degrees to discharge detergent from the cup 35.2. The bimetal strip 58 is cooled once more, and the wheel 25 rotates about 20 degrees until the finger 56 engages a tooth 55. Finally during the introduction of rinse water the tooth 55 is released and the wheel 25 rotates until a web 48 thereof engages the finger 56. During this final movement a scoop 62 carried by the wheel 25 collects wetting agent from a container 12 and throws it into a cup (not shown) from which it discharges into the washing chamber.

Abstract: 1,163,848. Nut-runners. CHICAGO PNEUMATIC TOOL CO. 3 Nov., 1967 [16 Dec., 1966], No. 50095/67. Heading B3N. A nut-runner comprises a sliding vane air motor 12, valve means 26, 53 controlling the air supply to the motor, a torque release roller and cam clutch 16, 18 for controlling the valve means, and a pneumatic pressure switch P-1 for controlling the air supply to the valve means. A plurality of the nut runners may be connected to an air manifold 44. In operation, air is supplied to manifold 44 at 77, and flows through ports 67 to a chamber 69, and through ports 43 to a chamber 29. The pressure builds up in chamber 69 and forces a piston 57 away from a switch contact 58. Air passes around main valve 26, through an annulus 46, a passage 73 and via a ball valve 74, into a further chamber 71, and when the pressure is built up in this chamber, piston 57 is moved upwardly, so as to close switch P-1 Air also flows through a passage 47 to motor 12, and through ports 48, 49 to a chamber 50 for balancing valve 26. Torque is transmitted to clutch 15, 16, and the nut is tightened. When the required tightening of the nut is reached, rollers 17 roll up the cam face of member 16, and the latter is moved axially against a spring 22, so that a valve spring 36 expands, and forces valve control rods 35, 41, axially, valve 26 is closed, and motor 12 stops. Air in chamber 71 is vented through passage 73, so that switch P-1 is opened, and a time relay starts to energize. Spring 22 is relaxed, the clutch is re-engaged, rods 35, 41 are moved upwardly causing the reclosing of valve 53, and air is again supplied to the motor through open valve 26. The tool repeatedly recycles without increased torque, until the time relay is finally energized, whereupon the air supply 77 is shut off, and switch P-1 is closed.
