Title: Method of carrying out exothermic gas reactions
IPC: B01J8/02
Filed: 1927-07-04
Abstract: 291,253. Harter, H. July 4, 1927. Catalytic apparatus; ammonia, producing from mixtures of nitrogen and hydrogen; nitric acid, producing by combustion of ammonia. - In exothermic catalytic processes, such as the synthesis of ammonia from its elements and the oxidation of ammonia to produce nitric acid, the gas supply pipe is subdivided into several branches and the outlet openings thereof distributed uniformly along the length of the catalytic tube. Additional cooling may be obtained by introducing the gases under pressure which is released at the moment of introduction or by similarly releasing the pressure on other gases which are introduced into the reaction chamber. The process enables the use of pure oxygen in making nitric acid. In the arrangement shown in Fig. 1 the conduit admitting the reacting gases into the catalyst is subdivided into three branches c, c<1>, c<2> along which the outlet openings are distributed evenly as indicated by the arrows. In a modification shown in Fig. 2 the gases are admitted at both ends of the catalyst tube and the products of reaction drawn off centrally through pipes e<1>, e<2>. In a further application, Fig. 3, ammonia oxidation is introduced through a, pipe c<4> and oxygen through a pipe c<5>. Branch pipes g, g<1>, issuing from these pipes at intervals, are wound in the form of coils and perforated with evenly spaced openings d. A gas inlet pipe may be subdivided by a median partition into channels through which ammonia and oxygen respectively may be passed,

A three-dimensional diaphragm for a measuring or controlling device for gases, is made by deforming a sheet-form reinforcing base material of a kind fabricated from fibres or threads and deformable into a threedimensional diaphragm without rupture or substantially greater loss of strength in one direction than another, into the required threedimensional shape, and rendering it impermeable to gas, or by providing such a material with a deformable proofing, deforming it into the required three-dimensional shape, and, if required, submitting the proofing to a curing operation. The base material may be a felted sheet of woollen or fur fibres or a combination of these with synthetic fibres ; or a knitted material, e.g. nylon or cotton, may be used. The proofing material may include polymers such as synthetic resins and synthetic rubbers, polyvinyl chloride and the substances known under the Registered Trade Marks " Hycar," " Vulcaprene " and " Thiokol," a mixture of " Hycar " and " Thiokol " being suitable. Knitted nylon or like synthetic fibre may be modified and rendered impermeable by hot rolling to form a fused film of synthetic polymer. In an example, wool felt or knitted cotton are spread with mixes containing " Hycar OR 15 " and vulcanizing ingredients and discs of the coated material vulcanized while shaped on a former of trucated conical form, or while stretched on a metal hoop and distorted by maintaining a pressure differential between the two sides. The first Provisional Specification refers also to the use of diaphragms of felts or matted woven fibres which may or may not be proofed.

Title: Improvements in or relating to lathes and like machine tools
IPC: B23B5/14
Filed: 1920-07-02
Abstract: 145,773. Bardons & Oliver, (Assignees of Oliver, J. G.). Feb. 19, 1916, [Convention date]. Lathes.-A lathe has improved means whereby, as the tool approaches the work axis, the speed of the work is increased so that the surface speed of the work against the tool remains approximately constant. The work spindle 10 is driven from an electric motor of the type wherein the armature is moved into or out of the field to vary the speed of rotation. The tool slide 12 on the main saddle 14 is fed by a screw 15 on one end of which is feathered a pinion 21, which drives through spur and bevel gearing, a sleeve 24 feathered to a shaft 50. This shaft is journaled in a fixed bracket 51 and carries a sprocket 53 which drives another sprocket 55 fixed to the armature positioning screw 41. As the feedscrew 15 moves the tool towards the work axes, the screw 41 operates through a fixed nut 42, rod 43 and lever 44 to move the armature into its field, thus simultaneously increasing the speed of rotation of the work and the rate of approach of the tool.

Title: Improvements in and relating to nuclear reactor safety rod actuators
Inventor: WINDERS GORDON ROBERT
IPC: G21C7/20
Filed: 1965-04-30
Abstract: 1,102,255. Controlling reactors. BABCOCK & WILCOX CO. 30 April, 1965 [1 May, 1964], No. 18253/65. Heading G6C. A safety rod actuator comprises a piston 124 in a cylinder 100 adapted for moving a safety rod 88 against gravity bias to a normal position outside of the reactor core, pressure fluid which may be the moderator-coolant fluid, e.g. steam at a pressure above the critical pressure, being led to a reduced diameter bore 120 at the lower end of the cylinder 100 so as to drive the piston 124 to its uppermost position and also to flow in a restricted annular fluid flow space between the piston 124 and the cylinder 100, a conical surface 127 at the upper end of the piston 124 mating with a conical surface 123 at the upper end of the cylinder 100 when the piston 124 is at its uppermost position so as to minimize fluid flow through the restricted annular fluid flow space. Where a number of such actuators are used, the maximum available total flow rate of the pressure fluid is sufficient to ensure upward travel of only one piston at a time and the pistons are raised sequentially, each succeeding piston being raised only after the preceding piston has been taken to its uppermost position in which it thereafter requires only a reduced fluid flow rate to be maintained in that position. If, during the sequential raising of the pistons to their uppermost positions, one of the pistons already raised should fall while another piston is being raised, all of the already raised pistons will also fall. When the last piston has been raised to its uppermost position, a smaller fluid flow is sufficient to maintain all the pistons in their uppermost positions than when the last piston is being raised. If the fluid flow rate is normally sufficient to maintain all the pistons raised but the maximum available total fluid flow has a predetermined value less than that required to raise the last piston, and if, starting from the condition that all the pistons are fully raised, one of them should nevertheless fall, a reduced flow resistance will be offered to the fluid outflow from the actuator system and as a consequence of the resulting pressure reduction, all the remaining pistons will fall. Such an actuator system is of the fail-safe type. Likewise, should failure occur in the actuator fluid piping system or in the reactor coolant circuit, all the safety rods will be inserted.

Abstract: 1,047,155. Spin drying. MAY-FRAN MANUFACTURING CO. May 4, 1964, No. 18400/64. Heading F4G. A spin drier for removing liquid from metal scrap comprises a shaft 10 driven by belting from a motor 20 to which shaft is connected a bell-shaped housing 28 having an inverted frusto-conical scrap deflector 36 spacedly mounted therein on the shaft to define a passageway therebetween, and an inverted frustoconical member 42 is spacedly secured by fasteners 50 to the housing 28 so as to extend outwardly and upwardly above the peripheral edge 38 of the housing 28. The member 42 is also secured to the shaft 10 by a spider 44 having arms 48 which also act as rotatable downdraught fan blades to provide stability. The scrap is fed by a screw conveyer 24 to the open hopper portion 26 of the housing 28 to drop on the deflector 36 and thereafter is forced downwardly by the inclination of the wall surface 30 of the housing and is assisted by pressure of scrap continuously fed into the hopper. The liquids adhering to the scrap are centrifuged to the surface 30 and forced downwardly until they are forced across the gap between the members 28, and 42 on to the inner wall surface 60 of the member, which due to its upward and outward configuration passes to a stationary reservoir 64. The scrap is collected at the base of the drier and continuously removed by a screw conveyer 72. Various modifications are described in which the deflector may be of plate-form or the deflector may be filled with liquid for stabilization purposes.
