Filed: 1957-06-25
Abstract: A lubricating oil comprises the reaction product of a permanently liquid organopolysiloxane with a tin halide in an amount of from 1 to 10% by weight of the siloxane.  The siloxanes disclosed are made by hydrolysing a mixture of 5 to 25 parts (by weight) of tetrachlorophenyltrichlorosilane, 55 to 92 parts of dimethyldichlorosilane and 3 to 20 parts of trimethylchlorosilane with 100 parts of water, with subsequent removal of the aqueous layer and heating of the liquid siloxane with 3 parts of H2SO4, HCl or H3PO4, followed by neutralization with Na2CO3, filtration and removal by devolatization of low boiling materials.  The siloxanes are then stabilized by heating to 460 DEG  F. with SnCl2 or SnCl4 until the liquid becomes clear, and finally stripped of low boiling materials under vacuum at 600 DEG  F.  Specifications 586,187 and 586,956 are referred to.

Title: Method of reprocessing and/or separating nuclear fuels
IPC: C01D17/00

Abstract: 1,037,952. Processing nuclear fuel. GELLESCHAFT FUER KERNFORSCHUNG. May 15, 1964 [May 15, 1963; July 6, 1963], No. 20474/64. Heading G6R. A nuclear fuel is reprocessed and/or separated by a method which comprises reacting the fuel with an alkaline fused salt system containing an oxidizing agent. The fused salt may consist of an alkali metal nitrate with or without an alkali metal carbonate or hydroxide. Molybdenum may be separated from uranium, UO2, or a mixture of UO2 and PnO2 by melting with sodium nitrate or a mixture of sodium nitrate and sodium bicarbonate, cooling, and extracting the product with water or dilute caustic soda to remove molybdenum. Caesium fission product may be removed in the same way, and, if both molybdenum and caesium are present, they are separated by adding phosphoric acid and nitric acid to precipitate caesium phosphomolybdate and then separating caesium by ion exchange. Ce, Ru, Nb, and Zr fission products are removed from irradiated UO2 by melting with sodium nitrate, leaching the melt with water, and dissolving the uranium in dilute acid, leaving the fission products as a residue. Mixtures of UO2 with PnO2 or ThO2 are melted with NaNO3 and the melt washed with water and dissolved in dilute HNO3; the uranium dissolves leaving a residue containing the Pn or Th. NaNO2 may be used in place of NaNO3 to form the melt with the UO2-PnO2 mixture. As the oxidizing agent, reference is made also to peroxides, chlorates, and perchlorates.

Abstract: 1,170,968. Sawing. ROCKWELL MFG. CO. 3 May, 1967, No. 20510/67. Heading B5L. A portable sabre saw comprises a blade driving member 43 mounted in a casing for rotation about a first axis 37 and driven by a motor 26, 27, a saw blade carrier 89, a carrier guide 90 mounted on the casing for pivotal motion about second axis 105 lying in a plane substantially perpendicular to the first axis, the guide having a guideway embracing and mounting the carrier for longitudinal reciprocation in a direction substantially perpendicular to the first and second axes, and motion transmitting means interconnecting the driving member and carrier whereby rotation of the driving member reciprocates the carrier relative to the guide, and means for adjusting the position of the motion transmitting means to selectively impart pivotal motion to the carrier guide and carrier about the second axis. The motor is mounted in a twopart casing 20 and is formed with a pinion 33 on its driving-shaft 29 engaging a gear 35 mounted on a shaft 37 in a gear casing 31a. The driving member in the form of a gear 43 is mounted on shaft 37 and engages a pair of gears 44, 47 provided with counterbalance weights 51, 53. A crank 60 mounted in gear 43 carries a bearing 63 in a crosshead 60a slidable in a guideway 87 secured to the blade carrier 89. The guide 90 for the carrier is mounted on the pivot 105, and the guideway 87 is inclined at an acute angle to a plane normal to the axis of shaft 37 so that as the gear 43 rotates to cause the pin 60 to reciprocate the blade carrier in the guide, inclination of the guideway 87 causes the carrier guide to rock about the pivot 105. The inclination of the guideway can be adjusted by rotational adjustment of bush 108 in the carrier, the bush having a square bore for receiving the blade carrier 89; the bearing 63 on the crank-pin 60 has a spherical external surface engaging a complemental surface in the crosshead to permit the adjustment of the inclination. The casing has a handle 23 housing a lamp 116 supplied with power from a dropping resistor, and a transparent member 121 conveys a light beam from the lamp to the sawing area.

Abstract: 1340613 Fuel injection systems; electromagnetic injectors SOC INDUSTRIELLE D'ELECTRONIQUE ET D'INFORMATIQUE 9 April 1971 [30 Jan 1970 8 Jan 1971] 20513/ 71 Heading F1B [Also in Division G1] In an electrically controlled fuel injection system for an I. C. engine, pressured is measured at two places in the air inlet pipe, at a constriction 16 adjacent a throttle 4 and at 17 downstream of the throttle, the signals derived from detectors 15, 18 being fed, together with a signal from an engine speed transducer 25 to a control circuit 11 to control a fuel injector 19. In the position of maximum throttle closure a member 8 contacts a screw 7 providing a further signal to the circuit 11. This also receives a signal from a sensor 22 indicating cooling fluid temperature. The pressure sensors 15, 18, each comprise a diaphragm Fig. 2 (not shown) which moves a brush 46 to tap off a potential from a potentiometer 47.  The injector Fig.4 comprises an armature 102 having a conical end 108 engaging a seating 109 under the pressure of a spring 110, the armature being withdrawn by a magnetic field produced by two coils 117, 118. Current through the winding 118 is such as to balance the spring so that armature movement responds linearly to current through winding 117. A modified construction is disclosed Fig.6 (not shown). As shown in Fig. 5 the signal derived from sensor 15 is amplified and fed as the input to the potentiometer of sensor 18 whose output is applied to a voltage-to-current circuit 132 feeding the thermometer 22. The voltage across the thermometer is fed to an operational amplifier 134 which is connected to a cut-out circuit 135 including a F.E.T. 136. Pulses from the speed sensor 25 trigger a monostable circuit 187 controlling the F.E.T. 136 so that the output of circuit 135 comprises pulses of variable amplitude and constant pulse length. This signal is filtered at 136 and the output, which is proportional to engine speed, is fed, together with the signal from 134, to an adding circuit 137 to provide connection for engine speed. This signal is applied to the rest contact of a relay 138 connected with a signal generator 139. The speed signal on line 28 is fed to a monostable circuit 142 giving an output impulse whose width defines the duration of the excitation of the coil 118 and this signal on line 28 is also fed, after delay, to the signal generator 139, whose output on 143 has a pulse duration appropriate to the injector opening time. This output is fed to the line 34 and coil 117 through an AND gate 143 unless inhibited by a signal on line 145 indicative of the member 8 engaging screw 7 at a time when the engine speed is above idling speed (deceleration). A modification using two magnets on sensor 25 is disclosed, and provision for four injectors is also envisaged Fig.3 (not shown).
