Title: Finned heat exchanger composed of pressure welded louvered passageway panels
Inventor: HABICH ADOLPH BRAUDUS
IPC: B21D53/04
Filed: 1957-03-21
Abstract: 805,630. Making heat exchangers. REYNOLDS METALS CO. March 21, 1957, No. 9351/57. Classes 83 (2) and 83 (4). Angular bending; shearing.-A method of making a heat exchanger, e.g. a condenser unit for an air-conditioning system, comprises integrally bonding together a pair of metal sheets at least one of which is formed to provide between the sheets a plurality of parallel passages interconnected at their ends and spaced by bonded areas, slitting the bonded areas to form a plurality of slats each incorporating a passageway and twisting the slats to lie at an angle to the sheets to form a louvred plate. Two flat aluminium sheets, Fig. 1, are integrally bonded together by pressure-welding with stop-weld interposed to define a pattern of unbonded areas, the latter being inflated by fluid pressure to form passageways 2 in the panel 1, spaced by bonded areas 3 and interconnected at the ends by inlet and outlet headers 4, 7 respectively and by cross-over headers 5, 6 connecting the interposed group " M " of passageways with the inlet and outlet groups " A " and " Z " respectively. An eccentric-operated upper bar 13, Fig. 6, then shears the first bonded area 3 along a line 9, preferably centrally situated between adjacent passageways 2 and on the same stroke twists the portion 3 to the position shown in Fig. 6, the panel 1 being clamped between U- shaped holding dies 11, 12. On moving the plate to the right a further bonded area is sheared along a similar line and both bars 13 act simultaneously during the cutting stroke to twist the passageway 2 with fins formed from the adjacent bonded areas out of the plane of the panel 1 to form louvres. A number of louvred panels so formed are mounted face-to-face and brazed or welded to side-walls, the passageways being connected to transverse inlet and outlet fittings. The finned passageways or tubes of adjacent panels may be staggered and the fins may lie at opposite angles of inclination, Fig. 8. In a modification the formation of the louvres may be carried out prior to expanding the unbonded areas into passageways. U.S.A. Specification 2,662,273 is referred to.

Abstract: 593,814. Vehicle spring-suspensions. AUSTIN MOTOR CO., Ltd., and HAEFELI, J. C. April 14, 1945, No. 9368. [Class 108 (ii)] In a spring suspension for steering wheels of the kind in which a spring supported carrier B of the steering pivot (not shown) is pivotally connected at its upper and lower ends to two longitudinally disposed links D, D' which are pivotally connected at their outer ends to the chassis frame or vehicle body, one link D extending forwardly and the other D<1> rearwardly, the links are so disposed that when one link tends to move its pivot axis with the carrier in one horizontal direction the other link will tend to move its pivot axis with the carrier in the same direction and by substantially the same amount to maintain the castor angle of the steering pivot constant. When the axle is somewhat below its normal vertical position in relation to the vehicle body the rearward link D<1> is arranged to be horizontal and the forward link is inclined downwardly towards the carrier. Alternatively the link D may be horizontal for the same axle position with the link D<1> inclined downwardly towards the carrier. In either construction as one link moves towards, the other link moves away from, the horizontal. The carrier may be directly supported by coil or other spring or, as shown, the outer ends of the links may be splined to torsion rods E, E' housed in tubes held at their outer ends in brackets f, f', the inner ends of the torsion rods being splined to the interior central region of the tubes. The carrier may be constituted by the steering pivot itself or may be a separate mounting carrying the pivot. Reference has been directed by the Comptroller to Specification, 569,492.

Title: Improvements in the purification of nitro derivatives of saturated hydrocarbons
IPC: C07C201/16
Filed: 1961-03-16
Abstract: Nitro-alkanes or cycloalkanes, prepared by nitration of the hydrocarbon, are purified by contacting a solution of the nitro compound in a hydrocarbon solvent with sulphuric acid containing at most 35% by weight of water, based on the total weight of water and acid, at a temperature between the freezing point of the mixture and the decomposition temperature of the nitro compound, the weight ratio of sulphuric acid (calculated as 100% acid) to the nitro compound being at least 0.1:1 and the hydrocarbon solvent being chemically inert to and substantially immiscible with sulphuric acid at the operating temperature.  The solution of impure nitro compound, for example, of nitrocyclohexane in cyclohexane such as may be obtained by incomplete nitration of cyclohexane, may be contacted first with 85-98% by weight sulphuric acid and then an amount of water added to provide a total water concentration of 14-35% weight when the nitro compound passes from the aqueous phase to the organic phase from which it may be recovered, e.g. by distillation.  The solution of impure nitro compound may first be pretreated by contacting with an aqueous solution of an inorganic base, e.g. 90-99% aqueous sodium hydroxide.  Other nitro compounds such as nitropentane, nitrohexane, nitrocyclopentane and nitrocyclooctane may be similarly treated.  In examples solutions of nitrocyclohexane in cyclohexane are purified. Cyclohexanone oxime may be prepared by catalytic hydrogenation of the purified nitrocyclohexane.  Specification 797,985 is referred to.

Filed: 1941-08-01
Abstract: 550,999. Condensers. DUBILIER CONDENSER CO. (1925), Ltd. (Dubilier, W.). Aug. 1, 1941, No. 9846. Drawings to Specification. [Class 37] [Also in Group XVI] A machine for assembling flat plate condensers comprises a stacking nest with a platform on which the sheets of insulation and foil are stacked. A hopper containing cut sheets of insulation, a hollow lifting tube to which vacuum can be applied, having a mouth brought into contact with the top sheet in the hopper so as to lift the sheet by suction and by moving the tube, to convey it to the nest, foil being fed between the sheets as stacked. In the machine described, four stacking platforms form the bottom, in turn, of a stacking nest. The vacuum mica-sheet conveying pipe is pushed down on to the uppermost of a stack of mica sheets in a hopper, and lifts are to transfer it to the platform in the nest and release it. A strip of foil from one of two oppositely located rolls is then fed in over the sheet and a knife severs it so that it projects over one edge of the mica. A second mica sheet is then deposited, and a foil fed in from the other side and cut off so as to project from the opposite edge. This is repeated a predetermined number of times and then a counter-operated switch operates mechanism to rotate the platform bearing disc to place another platform in position the stacked condenser being held by a cam-released spring clip on its platform and the switch restarts the stacking mechanism. As the stack on its platform moves away the edge is coated with. molten wax or adhesive, which coils on its further travel to a point where the stack is disengaged by an arm and falls down a shoot. In modifications a plurality of parallel metal foils are fed spaced apart on to a single mica sheet, the multiple condenser thus formed being subsequently cut between the foils. In a further modification a corresponding number of nests platforms conveying tubes and hoppers are provided to make a number of condensers at one time.
