Abstract: 802,756. Refrigerators. PRESSED STEEL CO., Ltd. May 31, 1957 [June 1, 1956], No. 17066/56. Class 29. The evaporator coils of a refrigerator are positioned in the space between the cabinet outer shell and inner liner, and all the joints of the outer shell are permanently sealed while the joints between the shell and liner are also permanently sealed save for one or a few, the latter being seated with a reluctantly pervious or breathing seal. The breathing seal is preferably adjacent the upper margin of the liner. As shown the outer shell 3 and the inner liner 4 are connected by a top frame 5 formed by spaced walls 8 and 9. The joint between the walls and the shell 3 is permanently sealed by plastic over which a bitumen compound is applied. A breaker strip 15 connects the other end of wall 9 with the inner liner 4. The lower end of the strip is sealed into a channel 16 formed on the inside of the inner liner, while the upper end embraces the end 13 of the wall 9. Either or both of these seals may be made by a mastic compound reluctantly impervious to air. A second breaker strip 20 is bolted to the wall 8 and loosely engages the end of the liner so that there is a relatively free flow of air to the pervious seal or seals. A gasket 23 for a top closure of the cabinet may be incorporated in the breaker strip 20.

Title: Improvements in or relating to the production of laminate, expandable strip stock
IPC: B21C37/14
Filed: 1960-05-17
Abstract: 952,064. Making ingots for cans; rolling. CONTINENTAL CAN CO. Inc. May 17, 1960 [Aug. 7, 1959], No. 17379/60. Headings B3A and B3M. A billet from which laminate, expandable strip-stock 60, Fig. 6, is produced for making cans is so formed as to predetermine the widths of the residues of the plurality of cores of stopweld remaining after the billet-thickness has been reduced. An iron or aluminium alloy billet may be cast and the stopweld channels 11-13 filled with stopweld during or after casting. The metal may be cast about encased stopweld, or channels for the stopweld may be machined in the casting. Alternatively, a pair of slabs, either or both of which have a stopweld channel, are joined by brazing or rollbonding to form the billet, which is filled with stopweld before or after joining. To compensate for differential lateral spreading during rolling the billet down to strip and thus predetermine the widths of the stopweld residues, longitudinal slots 14-16, Fig. 1, are formed which have successively greater cross-sections from the centre of the billet towards its edges E, as by increasing the depth or root-angle of the slots. Instead of, or in addition to, the slots, the crosssection of the billet may be tapered or curved at the edges 43, Fig. 3. The stopweld residues may each have the same width if the stopweld corewidths in a parallel billet vary from a maximum at the central areas 53, Fig. 4, to a minimum at the edge areas 51. Variable stopweld width may be combined with peripheral slots and a shaped profile (Fig. 3, not shown).

Abstract: 562,020. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 10, 1942, No. 17570. Convention date, Dec. 16, 1941. [Class 38 (v)] A safety device for an electric iron or other appliance which opens the circuit sometime after the handle is released comprises a thermally-actuated or thermally-tripped switch 21, 22 the heating means of which is short-circuited at 37, 38 when a manually-operated lever 47 or like device is depressed against the action of a return spring. In the form shown the device is mounted in the handle of an iron and when the handle is gripped or the iron is stood on end, a projection 51 closes contacts 37, 38 and a projection 52 moves a latch 36 allowing contacts 21, 22 to close. A circuit to the heater of the iron is thus closed passing through both pairs of contacts in series. If the handle is now released, contacts 37, 38 open but the current to the heater can still pass through contacts 21, 22 and the bimetallic strip 34 carrying the contact 22. The bimetallic strip 34 is thus heated and after a short time interval bends upwards into the position shown where it is held latched, the contacts 21, 22 opening to break the heater circuit. In a modification, Figs. 6-11 (not shown) the strip 34 consists of a spring and is not bimetallic. It is held closed by a bimetallic latch, which is short circuited by the contacts 37, 38.
