Title: Improvements in or relating to fluid systems and valves therefor
IPC: F16K31/122
Filed: 1949-08-25
Abstract: 704,941. Hydraulic machines; valves. BALLINGER, L. J. H. Aug. 25, 1949, No. 22134/49. Classes 69 (2) and 135 A hydraulic pressure system for the sequential operation of a pair of working cylinders comprises a first working cylinder 8, Fig. 1, having a piston 11 urged outwardly by pressure liquid and inwardly by springs 12, a piston valve 26 adjustably loaded by a weight 50 mounted on a lever 40, and a second working cylinder 19 having a piston 20 urged outwardly by pressure liquid and inwardly by springs 21. In operation, a manually-actuated cock 3 is rotated to connect a pump 1 to a duct 5 having branches 6, 7 leading to the cylinder 8 and the piston valve 26 respectively. The piston in the cylinder 8 moves outwardly until arrested by an adjustable stop 15 whence pressure in the system builds up to raise the piston valve 26 to connect the pump supply to the second cylinder 19 to move its piston 20 outwards. On completion of the working stroke of the piston 20, the cock 3 is moved to disconnect the pump from the system and connect the cylinder 8 to sump. The pressure in the system then falls and both pistons are urged inwardly by their respective springs substantially simultaneously. The first cylinder exhausting through the cock 3 and the second cylinder through radial ports 32, 34 in the piston valve and a line 25. The rotary cock 3 may, if desired, be arranged to simultaneously supply more than one " first " working cylinder. In a modification, the cock 3 has a ratchet wheel 57, Fig. 6, a notched disc 69 and adjustable pins 72. The wheel 57 engages a pawl 60 mounted on the second piston 20 so that on the outward stroke of this piston the pawl 60 rotates the wheel by one tooth to automatically connect the first cylinder to sump and as before return the pistons 11, 20 to their initial positions. The disc 69 engages a spring-loaded rod 74 so that on movement of the cock 3 from one of its ports to another a valve 67 closes to cut off the supply of pressure liquid to the cylinder 8. The pins 72 engage a bell-crank lever 73 to reduce the pump output when the valve 67 is closed.

Title: Improvements in or relating to electric starting systems for internal combustion engines
IPC: F02N11/08
Filed: 1934-08-02
Abstract: 439,750. Starting prime movers; electromagnetic switches. GEIPEL, Ltd., W., and PELL, W. GUY-, 156, Bermondsey Street, Bermondsey, London. Aug. 2, 1934, No. 22600. [Class 38 (iv)] [See also Group XXXVII] In an electric starting system for internalcombustion engines closure of a switch K causes energization of a contactor A to complete the starter motor circuit through a resistance so that the starter pinion and engine gear are engaged without shock. Switch K also energizes the coil C of a time delay relay which closes contacts C<1> after a predetermined time and causes energization of a second contactor A<1> which short circuits the series resistance in the starter motor circuit. The time delay relay and contactors are mounted on an insulator block 12<a> arranged on a hollow base 12 within which the resistance is arranged. The time delay relay C comprises a coil 3 mounted on a core 2 having two end pieces 1, 1<a> and a spring controlled armature 4 pivoted on the end piece 1 and extending opposite the end pole piece 1<a>, the unattracted position of the armature 4 being determined by an adjustable stop 5. Attached to the armature 4 is a spring contact member 6 having a contact 9 co-operating with an adjustable fixed contact 10<a>, and being attached to the shaft 13<c> of a dashpot 13. The contactors A, A<1> are of identical construction and each comprise a coil 18 mounted on a base having a central pole piece 17<a> and upstanding side pieces 17, 17b. An armature 19 is pivoted at 19<a> on the projection 17 and is biassed by gravity to the open position, but when the coil 18 is energized, is attracted until the end of the armature bears against the projection 17b leaving an air gap between the armature and the pole piece 17<a> to permit the armature to fall off when the coil is deenergized. A roller 29 mounted on a spring 28 secured to the member 17b is arranged in the path of the armature 19 so as to prevent excessive movement thereof due to vibration. Secured to the armature 19 is a cross-piece 20 which terminates in a U-shaped bracket 20a in which the movable contact member 16 is secured said member having a curved face arranged to co-operate with a fixed contact 15. Contact member 16 is connected to a terminal 27 by means of a flexible lead 26 and is connected to the bracket 20<a> by means of a spring pressed collar 22 and a pin 21 passing through the collar and connected to the bracket 20<a>. The pin 21 is a loose fit in the aperture in the contact member 16 and the bracket 20<a> is provided with a spherical projection 24 on its inner face so that, as the bracket 20<a> is swung about the pivot 19<a> of the armature 19, the curved face of the member 16 rolls on the contact face of the member 15. Specification 145,095, [Class 38 (iv)], is referred to.

[Also in Division G6] A nuclear reactor plant includes a plate or tubular heat exchanger wherein the heated and heating fluids are separated by an intermediate exchange fluid, the heat exchanger and the reactor core (13, Figs. 1 and 2) being disposed in the same container (12) and the reactor coolant being pumped through the core and the heat exchanger in a closed circuit. The tubular heat exchanger 14 particularly described comprises an outer cylindrical chamber divided into sections 30, 33 and 34 by members 39, 31, 32, and 40 with members 39 and 40 carrying hemispherical water inlet and steam outlet headers 42 and 41 respectively, which are in communication with one another by means of pipes 46 extending through the chamber. Within section 30 of the chamber, pipes 46 are coaxially surrounded by further pipes 49 which extend between members 31 and 32 and fit into recesses 48 formed at the inner ends of holes 47, the holes having a bore of greater diameter than that of pipes 46. Helically wound spacers (50) are provided between tubes 46 and 49 with alternate tubes 49 having further external helically wound spacers 51. The tubes 49 are held together in a bundle by axially spaced ring clamps 52. Section 33 is made with a bellows portion 37 to accommodate thermal expansion of the compound chamber. Inlet 35 and outlet 36 facilitate the introduction of a static intermediate liquid heat transfer fluid which fills sections 33 and 34 and the space between pipes 46 and 49. Liquid metal coolant, which has been heated by nuclear fuel, is supplied through duct 21 to section 30 where it transfers its heat to the intermediate transfer fluid before leaving through an outlet (17) to be recirculated. Water supplied to the lower header 42 on passing through the tubes 46 is thus heated and steam collecting in the upper header 41 is extracted through outlet 44. The invention is however not restricted to steam generators and any suitable fluids may be circulated through the heat-exchanger.

Title: Improvements in or relating to a method of nitriding steel
IPC: C23C8/70
Filed: 1963-06-07
Abstract: Low-carbon (0.03-0.15% C) steel is nitrided, e.g. to N contents up to 0.08%, by coating the surface of the steel with a film of a nitrogen-containing compound which decomposes and only releases most of its nitrogen above 600  DEG F., and maintaining the coated steel e.g. in the form of coiled strip or wire or stacked in a nitriding atmosphere at a temperature e.g. between 600  DEG F. and 1300  DEG F. at which the compound is decomposed for a time sufficient to nitride the steel throughout.  To minimize denitriding of e.g. coil edges, externally generated ammonia may be introduced into the furnace atmosphere.  Suitable nitrogen-containing compounds are guanidine compounds such as cyanoguanidine, guanidine carbonate and chloride; ammonium carbonate or urea are unsuitable for the invention.  The film is preferably provided by applying to the steel an aqueous solution of the compound.
