Title: A new or improved method of and apparatus for forming sheet metal structures
IPC: B21D53/04
Filed: 1950-08-10
Abstract: 695,640. Making heat-exchangers. RICHINGS, J. W. Aug. 10, 1951 [Aug. 10, 1950], No. 19877/50. Classes 83 (ii) and 83 (iv). Stamping; welding.-A process for making hollow sheet-metal structures, e.g. heat-exchangers, comprises applying welding pressure by means of a pair of cooperating dies to selected registering areas of the outer faces of two sheets placed between the dies so as simultaneously to weld the margins of the sheets together to render the space between the sheets fluid-tight and also to weld the sheets together inwards of the outer marginal seam to define the internal configuration of the structure and applying fluid pressure between the sheets to expand portions against which said welding pressure is not applied, the degree of expansion being controlled by cavities in the said co-operating dies. Apparatus for carrying out the invention comprises a pair of dies 10 and 11 and a nozzle 12 for injecting pressure fluid preferably air or other gas from a flexible pipe-line 13. A seating 16 and 17 of resilient material is interposed between the dies and their carrying members 14 and 15 of the press. The lower die 11 has pressure-plates 18 for limiting the inward travel of the dies and the dies are located laterally by dowels 19 and bushings 20. The metal sheets 25 and 26 are located between the dies by cylindrical posts 21 having conical outer ends 22 and rectangular posts 23. Each of the dies is provided with cavities 27 and raised portions 28 and 29. The nozzle 12 has a portion 30 of elliptical cross-section for withstanding the lateral pressure of the dies and initiates expansion of the metal sheets. The pressure-fluid passes through passageways 31 and 32 in the nozzle and a flange 33 seated in a recess in the dies retains the nozzle in position. The plates may be of aluminium or copper alloys or sheet steel and the dies may be heated by electric heating elements placed in passageways, 34 or by a heating medium passing through these passageways. The welding may either be effected simultaneously with the expansion of the sheets into the die cavities 27 or prior to the introduction of the pressure fluid to effect such expansion. Specification 695,628, [Group XIII], is referred to.

Abstract: 709,050. Specific gravity estimating apparatus. GENERAL MOTORS CORPORATION. Aug. 7, 1952 [Aug. 18, 1951], No. 19926/52. Class 97(3) [Also in Group XXVI] Apparatus for indicating liquid density comprises a casing 20 having a shaft 22 journaled in bearings 21, 21a therein and splined at 23 for connection with a power drive and at 24 for connection with a hub 26 carrying a plate 27 and with a carriage 38 pivotally supporting pairs of floats 53, the floats of each pair being of equal density and disposed at diametrically opposite positions. The carriage and the plate are located within a chamber 32, connected at 36 to the carriage, and the latter is urged to the left in Fig. 1 by a lever 71 carried by a disc 73 moving a density scale 77 and urged clockwise by a spring 74. To each pair of floats there corresponds a pair of pads such as 7p on plate 27 against which said pair of floats are adapted to bear when the liquid in the chamber 32 is of the same or less density as that pair of floats, these pads being located at different distances axially of the shaft. In use, liquid is introduced into the chamber through an inlet in hub 26 and the shaft is rotated. The floats of densities greater than the liquid move away from their pads on plate 27 and carriage 38 therefore moves axially into a position determined by the engagement of that pair of floats having density nearest that of the liquid with their corresponding pads. Such movement of the carriage is imparted to the disc 73 so that a reading of the liquid density can be made on a scale 77. Disc 73 is connected to a valve rod 85, the movement of which is followed by a piston 87 for controlling the flow of liquid in accordance with its approximate density.
