Title: Method of making sheet metal elements with expanded passages therein

Abstract: 793,364. Making heat exchangers. IMPERIAL CHEMICAL INDUSTRIES, Ltd., and MANNING, I. Dec. 9, 1955 [Dec. 1, 1954], No. 34770/54. Classes 83 (2) and 83 (4). Stamping.-A method of making metal elements, e.g. refrigerator evaporator panels, having a passage or passages therein and one side smooth, comprises cold pressure welding together two metal sheets having different deformation characteristics with stop weld material therebetween where the passage or passages are to be formed and subsequently expanding the passage or passages by the application to the non-welded areas between the welded sheets of a pressure which is sufficient to cause deformation of one sheet only. The metal sheets may be of dissimilar thicknesses. One of the sheets may be aluminium or copper and the other an aluminium or copper alloy. Alternatively, the sheets may be of two different alloys of the same base metal. The stop-weld material, e.g. polythene, poly-isobutylene or methyl methacrylate polymer, is applied by silk screen printing, as a film or as a solution or dispersion. Where hot inflation of the passages is to be carried out by decomposition of the stop-weld material, the materials for the sheets require to have different tensile strengths at the temperature of inflation. When the passages are to be expanded in the cold-rolled sheet, the materials for the sheets are selected for their difference in resistance to cold working. Materials having different heat treatment characteristics may also be used when cold expanding the passages. Thus a precipitation-hardening alloy may be used in conjunction with a non-heat-treatable metal or alloy. Clad aluminium base alloys are preferably used to improve the bond between the sheets and to increase corrosion resistance.

A thermal switch comprises a temperaturesensitive capsule 6 which moves a cam 20, 4 rectilinearly to actuate an electric switch 1, e.g. a microswitch which is spaced radially from the path of movement of the cam. The cam has a frusto-conical or pyramid section 20 and a cylindrical section 4 and the arrangement is such that the switch 1 cannot be harmed by overtravel of the capsule 6. The capsule is mounted in a support 5 which carries a housing 3 for the cam and its return spring 2. The microswitch or microswitches is or are vertically adjustable between two radial mounting cheeks. Each microswitch is actuated through a pivoted member 13<SP>1</SP> which projects through an aperture in housing 3. Further microswitches may be mounted in additional pairs of cheeks spaced around the housing. The housing 3 is angularly adjustable relative to support 5 and is retained in position by set screws 7. The purpose of the adjustment is to bring the microswitch into engagement with a different cam surface of the cam and also to make wiring easier. The housing 3 may be rotated by a timer acting through a toothed wheel, so that the microswitches are brought into engagement with different surfaces of the cam and control a desired programme. Alternatively, the cam may be rotated.

Abstract: 1392696 Breechblock safety devices WERKZEUGMASCHINENFABRIK DERLIKON BUHRLE AG 25 July 1973 [28 July 1972] 35361/73 Heading F3C A longitudinally movable breechblock 2, 3 is prevented from reaching its firing position by a pivotal catch element 29, spring biased into the obstruction position, and a second catch element 49 spring biased from the obstruction position, the elements being held in the obstruction positions by engagement by a blocking element 39. The breechblock comprises a head 2 and a control element 3 driven by lugs 9 from spring driven sleeves 10 on either side of the breechblock. When the breechblock approaches the firing position, the left-hand sleeve 10 (lower sleeve, in Fig. 6), engages a tapered surface of the catch element 29 and is checked so that its lug contacts the rear wall 87 of a complementary groove, Fig. 4. The breechblock is still driven by the right-hand sleeve 10 (upper sleeve, in Fig. 6), until firing whereupon the control element 3 recoils but is checked by the forward moving left-hand sleeve 10. To prevent firing, a two-way valve 80, Fig. 7, is operated to connect an hydraulic piston 68 and cylinder 66 to a pressure supply, to operate, via a piston rod 69, 74 and bell cranks 61, a member which rotates the pivotal blocking element 39 to move outwardly the catch elements 29, 49 by engaging tapered surfaces thereof. Usually, the element 29 provides the safety function, but if this fails, the element 49 acts as such, the breechblock being allowed to move a small distance forward in the latter instance.

[Class 98 (ii).] In a machine for developing diazotype prints, the sheets to be developed are guided onto a developer roller by means of a set of thin blades or vanes set at right angles to the roller and spaced apart. The blades may be mounted on a shaft parallel to the axis of the developer roller so as to be movable into and out of the operative position, in which position a small clearance is left between the blades and the roller. The blades may be formed as blocks having a projecting central rib of the same curvature as the roller. After leaving the developer roller the sheets may be passed between or over absorbent surfaces or rollers. In the form shown, the sheets are passed over a roller 1, revolving in a bath 2 of developer fed from a bottle, being guided by vanes 7 spaced apart by blocks 30 on a shaft 31. The sheets are removed from the roller by take-off fingers 11 and passed by transfer vanes 12 to a pair of absorbent rollers 13, 14. The absorbent rollers may consist of discs of blotting paper clamped on a shaft, of a number of refractory fireclay cylinders on a shaft 17, or of a layer of blotting paper wound on a metal cylinder. The shaft 31 carrying the vanes is borne by arms 9 pivoted at 10. The shafts of the developer roller and the lower absorbent roller are coupled by a chain 15.
