Filed: 1954-05-26
Abstract: 746,445. Sewing-machines. SINGER MANUFACTURING CO. May 26, 1954 [June 9, 1953], No. 15503/54. Class 112. In a sewing-machine comprising a bed 1 and a standard 2 rising therefrom, means for putting the feed out of action comprise a rod 43 slidable longitudinally of the bed, a rod 53 journalled in the standard, an operative connection between the rods such that rotation of the latter imparts sliding movement to the former, and a handle 55 which is fixed to rod 53 for rotating it and which is normally disposed within a recess 54 formed in the standard. The handle coincides in shape and size with the recess, and in one end position has its outer surface flush with the adjacent wall parts of the standard, the latter being formed with a finger well 59 and with abutments 62, 63 for the two end positions of the handle. Rod 53 carries a crank-pin 51 disposed in a slot 50 formed in a block 49 integral with rod 43, whereby rotation of rod 53 moves rod 43 to couple or uncouple lugs 45 and 47. Lug 47 is fixed to an enlarged portion 35 of the feed-lift shaft 30, and lug 45 is carried by a block 40 which is journalled on a reduced end portion 33 of said shaft and which receives oscillatory movement via a fork 41 projecting laterally from the block. Portion 33 extends into a bore 34 in portion 35 and is secured therein by screws 36. When rod 43 engages lug 47, crank-pin 51 moves into a stop position located beyond its position of maximum throw, whereby any forces tending to disengage rod 43 will also tend to urge pin 51 more firmly into its stop position. When handle 55 is rotated to its dotted position, Fig. 6, to withdraw rod 43 from lug 47, a spring 57 rotates shaft 30 for depressing the feed dog below the throat plate of the machine.

Title: Improvements in or relating to temperature control circuits
IPC: H05B1/02
Filed: 1949-06-10
Abstract: 659,658. Automatic temperature control systems. CONTINENTAL SILVER CO., Inc. June 10, 1949, No. 15504. Convention date, June 17, 1948. [Class 38 (iv)]. A temperature control system for an electric heating receptacle, e.g. a coffee pot, comprises a heater 11 fed through two paths 28, 19, each including a thermostat 32, 22, respectively, responsive to the temperature of the liquid in the receptacle, the thermostat 22 operating at a lower value than the thermostat 32. Initially current is supplied via both paths to the heater 11 but on the attainment of a first predetermined temperature the path 19 is broken by the thermostat 22, heating continuing via the path 28 until a predetermined maximum temperature is reached, the heater being then de-energized completely by thermostat 32. Thermostat 32 is restrained from reconnecting the heater as the liquid in the receptacle cools by means of an auxiliary heater 55 which becomes energized upon the breakage of the path 28. The liquid therefore cools to the first predetermined temperature, and is then maintained at that temperature by the action of the thermostat 22. A pilot lamp 39 is connected across the heater 35 for indicating when the maximum temperature has been reached.

Abstract: 911,510. Thermonuclear apparatus. FABRIK ELEKTRISCHER APPARATE SPRECHER & SCHUH A.G. May 3, 1960 [May 4, 1959; April 6, 1960], No. 15598/60. Class 39 (4). Apparatus for generating energy from thermonuclear reactions comprises a chamber, two electrodes in the chamber between which an arc may be struck, a reaction nozzle annularly surrounding a portion of the arc, and means for feeding a reaction medium into the nozzle. In Fig. 1, an arc is struck between electrodes 3 and 4 and the central part of the arc is surrounded by a nozzle 6 to which fuel, e.g. deutenium and/or tritium in gaseous or liquid form, is fed through a duct 11 which preferably enters the nozzle 6 tangentially. The pressure of the incoming fuel assists in stabilizing the discharge and gas heated by the discharge passes out of the chamber to a heat exchanger 8, where it gives up useful heat, and through a purifying unit 9 back to the duct 11. In a modified apparatus, Fig. 3 (not shown), the arc electrodes are tubular and hot gas is withdrawn from each end of the chamber. Energy may be extracted from the plasma discharge electrically by providing magnetic fields transverse to the plasma column which is thus split into positive and negative beams which are directed against electric fields to which energy is thus supplied.
