Title: Improvements in the production of shaped bodies from rubber-like conversion productsof drying and semi-drying oils
IPC: C08L91/00
Filed: 1952-07-02
Abstract: Rubber-like conversion products of drying and semi-drying oils for the production of moulded articles, linoleum, synthetic leather, and like products are prepared by contacting drying or semi-drying oils with alcoholates of polyvalent metals or with alkoxo salts at normal or elevated temperature.  The metal alcoholates or alkoxo salts may be used dissolved in a tautomeric compound able to form an enolic hydroxyl group, or in the form of a synthetic resin prepared from the metal alcoholate or alkoxo salt and a tautomeric compound.  The presence of the tautomeric compound facilitates the formation of the rubber-like products. Preferably the oil is run into the molten alcoholate or a solution thereof and stirred or vice versa, the gelled state resulting in a short time.  With a smaller proportion of alcoholate, the mixture is preferably heated.  The oils exemplified comprise linseed, sardine, soya and castor oil.  The alcoholates and alkoxo salts specified comprise aluminium, ferric and cobalt-aluminium compounds; in particular aluminium butylate, ferric butylate, and cobalt-aluminium butylate.  The tautomeric compounds may comprise acetoacetic ester, malonic acid ester, acetylacetone, and formyl compounds of the type of formyl acetophenone.  The alcoholate may be used in solution, toluene and butanol being exemplified.

Title: Improvements in and relating to powdered metal moulding
IPC: F16C33/12
Filed: 1958-05-27
Abstract: A powder mixture comprising one or more of iron, copper and aluminium of 5-60 micron size, with 3%-25% of colloidal graphite is cold pressed at a pressure of at least 2000 atmospheres, sintered at a low temperature and then hot pressed at 1500-4000 atmospheres to form a sintered body with the graphite trapped in the interstices of the metal matrix.  The mixture may also contain up to 15% by weight of the iron, copper or aluminium of zinc, cadmium, lead or tin and up to 9% of antimony, cobalt beryllium or manganese.  The graphite is preferably smaller than 1 micron and may be added as such or first granulated to a size of 200-500 micron.  The metal powders used have a mixed range of sizes between 5 and 60 micron and the sintering temperature must be below the entectic temperature of the mixture. In the examples this temperature varies between 660 DEG C. and 850 DEG C.  Specification 892,847 is referred to.

Title: Improvements in or relating to a nuclear reactor and to a method of operating same
IPC: G21C7/00
Filed: 1958-05-27
Abstract: 894,902. Controlling nuclear reactors. BABCOCK & WILCOX CO. May 27, 1958 [May 29, 1957], No. 16889/58. Class 39(4) Shim control of a nuclear reactor is achieved by increasing the moderating capacity of the core as fuel is consumed so that the remaining fuel still forms a critical mass. Variation of the moderating capacity can be used for operational control by shifting the neutron spectrum; in breeder reactors this leads to increased resonance captive and a higher breeding ratio. In Fig. 1 the pressurized water reactor 10 has as coolant and moderator a mixture of 90% D 2 O and 10% H,0. Moderating capacity is reduced by introducing D 2 O into the coolant circuit at 23 and increased by introducing H 2 O at 25, excess coolant being discharged at 27 to a D 2 O recovery plant 29. Other moderators suitable for this form of control are: Be dust in fluidized graphite dust; glass beads in light water; graphite dust in light water; steam in graphite rods or matrix. The invention may be applied to a fast reactor by inserting a moderator after consumption of some of the fuel. U.S.A. Specification 2,708,656 is referred to.

Title: Pressure fluid operated tool
Inventor: PEARSON NEVILLE BARRY
IPC: B25C1/04
Filed: 1968-04-09
Abstract: 1,260,285. Safety arrangement in a pressure fluid-operated tool. N. B. PARSON, and S. M. ROSE. 16 Jan., 1969 [18 Jan., 1968; 9 April, 1968], Nos. 2892/68 and 16901/68. Heading B4C.  A pneumatically-operated tool including a piston 53 and a blade 49, for driving a fastener, e.g. a nail or staple, or to which a tool kit is connected, a chamber 2 connected with a source of compressed air, and a differential piston-type valve member 21 comprises means for preventing operation of the tool unless it is held against a work surface. The means includes a duct 43 and conduit 42 joining the chamber 2 and the nose 40 of the tool, a duct 37, 38 joining the nose and a chamber 35, sealing members 46, 47, and a spool valve 32. The conduit 42 may have a ball valve (as shown) which is unseated upon application of the tool to a work surface or a manuallyoperable valve. In operation, when the tool is pressed against a work surface compressed air passes via duct 43, conduit 42 and duct 37, 38 to move the spool valve upwardly, thus opening chamber 22 to atmosphere via ducts 27, 28 and 33. The valve member 21 is thus raised from its seating on apertured disc 18 and compressed air acts on the upper surface of the piston. The space below the piston is initially open to atmosphere via gap 50. When the space is closed to atmosphere the air below the piston is compressed until the piston abuts a resilient buffer 10, in which position compressed air passes via annular valve member 56 into space 4 and via apertures 55 into the space below the piston. Withdrawal of the tool from the work surface causes the spool valve to return to its initial position thus opening the chamber 22 to the chamber 2 and closing the chamber 22 to atmosphere. The valve member 21 is thus moved downwardly to seat against the disc 18 and to open the space above the piston to atmosphere via ducts 14, 15. The piston 53 is then returned to its initial position, by air therebelow. When a bit is attached to the blade 49, the tool includes means providing a succession of pressure impulses to the piston whilst the tool is pressed  against a work surface.

Abstract: 627,152. Temperature-responsive actuating-elements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 26, 1947, No. 16903. Convention date, Aug. 17, 1940. [Class 64(ii)] [Also in Group XXXVII] A snap-acting thermostat comprises a snap-acting bimetallic element 14 and a resilient member 16 secured at one end to a supporting structure 12 and at its other end rigidly attached to the bimetallic element at a point in the central longitudinal axis of the element, said resilient member constituting the sole place of support of said element. In the form shown, the bimetallic element comprises a central longitudinally-extending strip 14a separated by a slot at each side thereof from outer strips 14b which extend substantially parallel to the central strip 14a and which are crimped so as to cause the structure to be flexed to an arcuate configuration. The resilient member 16 comprises an elongated spring-member, rigidly attached to the bimetallic element by means of a rivet 32 and slightly bent along a transverse line 17 before being fixed in position, so as to bias the bimetallic element downwardly to a contact-engaging position. The temperature at which the contacts 27, 28 are opened by the snap action of the bimetallic member may be varied by means of an adjusting screw 18 the rounded end of which engages the resilient member 16 and which is threaded into the supporting structure 12 of insulating material, e.g. phenolic resin or the like. Terminals 16, 36 are provided for connection in or to a suitable electric circuit to be controlled by the thermostat.
