Filed: 1938-06-22
Abstract: 563,462. Radiators for cooling. BROWNSDON, H. W. and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 22, 1938, No. 18602. [Class 64 (iii)] The core or matrix of a heat-exchanger is made by applying a thermosetting resin composition to the ends of assembled. metallic tubular or corrugated plate like elements 6 of the exchanger and subse. quently converting the composition into the hard ened condition to forma fluid-tight joint with the metallic exchanger ele ments. Prior to applying the resin composition, the exchanger elements may be held in assembled position in a jig, by riveting, by clips, or by spot welding. The ends of the elements may be roughened by sand blasting, and a coating of adhesion-promoting composition may be applied to ensure that the resin will form a fluid-tight joint. The fluidtight cellular structure is inserted in an outer casing 8 and is bonded to end plates 9 by rubber sealing-rings, or by applying non- metallic cement or thermosetting resin to the assembly. The end plates 9 may be formed of synthetic resin during the application of the resin to the ends of the elements, by dipping the assembled exchanger elements in an open mould containing the resin and provided with upstanding cores adapted to enter the apertures of the elements, a space free of the cores being provided at the periphery of the mould. The mould is then heated to convert the resin into the hardened condition, and the other end of the assembled exchanger elements is then treated in a similar manner. By means of the process the tubular or like elements of heatexchange devices such as oil-coolers; radiators for internal-combustion, engines, &c. may be made of light metal such as aluminium, or light metal alloy.

Title: Improvements in or relating to sound reproducing systems and apparatus therefor
Filed: 1928-06-27
Abstract: 319,715. Tomlins, F. C. June 27, 1928. Electric circuit arrangements.-In the reproduction of sounds from gramophone records or talking pictures, continuous reproduction from a number of record carriers is obtained without sudden change by automatically causing the volume of sound from the end portion of one record to decrease gradually whilst the volume of sound from the commencement of the next record is gradually increased. In the arrangement shown, the tracking arm 3 of an electrical pick-up 1 when nearing the end of one record closes a switch 9 to operate a relay 11 and energize a stepping- magnet 13 to rotate a wheel 15 connected to a fader-switch arm 18. This switch arm controls a network of resistances R connected at the end 22 to the pick-up 1 the output from which is to be diminished, and at the end 23 to the pick-up 2 the output from which is to be increased. The contact strips 28, 29 of the fader-switch are connected through transformer 30, valve-amplifier 31, and transformer 32 to a loud-speaker 34 and the movement of the switch arm over contacts x, y, causes a progressive increase in the resistance in the circuit of the pick-up 1 and a progressive decrease in the resistance in the circuit of the pick-up 2. When the movement of the switcharm in one direction is complete, an arm 21 on the wheel 15 opens a switch 19 to stop the stepping-magnet 13. The arm 4 of the pick-up 2 acts in a similar way to energize a stepping-magnet 14 to reverse the movement of the fader-switch when the pick-up 2 nears the end of its travel. A modification is described in which the faderswitch is operated by an arm which rotates in one direction only.

Title: Improvements in or relating to the recovery of caesium
Inventor: MOSS JOHN HICKMAN
IPC: C01D17/00
Filed: 1961-05-25
Abstract: Caesium is separated from an aqueous solution by adding a bromide and bromine to the solution, thus forming caesium polybromides, contacting the solution with a water-immiscible solvent for caesium polybromides and removing the caesium from the solvent.  The removal of caesium may be effected by first eliminating bromine from the solvent, when the caesium polybromides break down to monobromide which is insoluble in the solvent.  The preferred method for the removal of bromine is by steam stripping as this introduces an aqueous phase in which the monobromide is soluble.  The bromine is preferably added in the waterimmiscible solvent, e.g. nitrobenzene. To ensure that the solvent is always heavier than the aqueous phase it is convenient to add a dense inactive diluent, e.g. 12% carbon tetrabromide, 15% sym-tetrabromoethane or 15% bromoform.

Filed: 1920-07-07
Abstract: 147,207. Jay, W. July 18, 1917, [Convention date]. Vacuum apparatus. -Apparatus for raising fuel &c. from a lowlevel tank to a higher chamber comprises a vessel 1 connected to the atmosphere by a port 5 controlled by a valve 6 and to a source of suction by a pipe 7 controlled by a valve 8. The valves are operated by means of levers 10, 11 actuated by the rise and fall of a bell-float 13. The fuel-inlet pipe 17 discharges into the bell-float and is connected to the upper part of the vessel 1 by a duct 17<b> to prevent syphon action back to the lowlevel tank and to empty the pipe during discharge of the vessel 1 into the other vessel. During the descent of the bell, the air flows round the lower edge to break the partial vacuum in the bell and displace the liquid therein. During the rise of the float, this carburetted air is displaced from the bell and is drawn through the pipe 7 into the intake manifold. This arrangement prevents pure air from being drawn into the manifold to dilute the mixture.
