Abstract
741,789. Switching systems for heating resistors. STENSHOLMS FABRIKS AKTIEBOLAG. Dec. 8, 1953 [Dec. 9, 1952], No. 34139/53. Class 38 (4). An energy regulator for heating resistors 18, 19, or the like, comprises an operating shaft 6 carrying cams 5, 15 which control, respectively, the setting of a thermally-operated cycling switch 2-4 and the opening and closing of a pair of switch contacts 16, the arrangement being such that over an initial angular range of movement of the shaft the setting of the cycling switch, which is heated by the passage therethrough of the current traversing resistor 18, is progressively increased so that the energy input to resistor 18 is progressively increased also. Over this range cam 15 maintains contacts 16 open, so that resistor 19 is not energized. Over a second range of angular movement of the shaft (separated from the first range by a short gap in which the cams cause both contacts 4 and 16 to be open) cam 5 again causes the energization of resistor 18 to increase progressively with increasing rotation of the shaft but cam 15 switches resistor 19 directly across the supply. In a final position of the shaft a further cam 10 closes contacts 11, there. by short-circuiting the cycling switch, so that both resistors are permanently energized. In another arrangement a third resistor is subsequently connected in parallel with the resistor 19. A further arrangement provides for the following connections : (a) two resistors in series controlled by the cycling switch, with or without a permanently energized third resistor, (b) one resistor permanently energized, (e) two, or three, resistors permanently energized in parallel. Specifications 587,947, [Group XXXVII], and 587,953 are referred to.
