Title: Improvements in and relating to process of producing iron or steel directly from the ore and controlling the sulphur content thereof
IPC: C21B13/00
Filed: 1929-07-12
Abstract: 316,303. Davis Steel Process Corporation, (Assignees of Davis, E. W.). July 28, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Extracting.-In a process for producing molten iron or steel directly from the ore and controlling its sulphur content, a mixture of ore, carbon, and fluxing materials is heated in a reverberatory furnace until the ore was reduced. The temperature of the furnace was then maintained at such a value that the carburization of the reduced metal proceeds at such a rate that oxidation of the metal is prevented and the iron oxide content of the slag is maintained sufficiently low so as not to prevent the removal of the sulphur from the metal. If, for example, the furnace is being operated at 1600‹ C. with a neutral slag, the carbon content of the charge is increased; if the furnace is being operated at 1500‹ C. with a neutral slag the temperature is increased to about 1600‹ C. With a strongly acid slag the basicity of the slag-forming material is increased. Specification 315,760 is referred to.

IPC: A47J36/34
Filed: 1936-08-06
Abstract: 467,136. Grilling-apparatus. RINGENSON, E. V. Aug. 6, 1936, No. 21667. [Class 126] [Also in Group XVII] A grilling-apparatus comprises a heat-conducting imperforate plate 4 provided with a support 3 for a grill 5 consisting of two wiremesh lattices which are preferably hinged together. The support 3, which in the form shown in Fig. 1 consists of a wire ring welded to the plate, supports the grill at a distance above the latter, and the plate serves to distribute the heat from a source below it uniformly over the grill. To secure greater uniformity in cases where the centre of the plate is heated more than the peripheral portions, the plate may be dished downwardly so that the less heated parts are closer to the grill. Fig. 3 shows a modification in which the plate 4 is formed with upturned sides and provided with a cover 7 to form a pan enclosing the grill, the handle of which extends through a recess in the side. Feet 2 are provided.

Title: Improvements in and relating to an arrangement in sewing machines

Filed: 1948-08-17
Abstract: 639,527. Sewing-machines. PEDERSEN, H. Aug. 17, 1948, No. 21725. Convention date, Sept. 13, 1944. Drawings to Specification. [Class 112] Threads, controlling.-In order to enable the thread used in a sewing-machine to be changed without threading the new thread through the take-up, tension device and other guiding and controlling members, all these members, or the thread-handling parts of them, are duplicated so that the only change needed is at the eye of the needle ; the end of the thread not being used is held in a clip on the lower end of the needle-bar. The take-up eyes may be placed side by side in a single take-up arm, or the arm may be forked and have an eye in each limb : in the latter case, to facilitate threading each eye may be open at the top, with a spring tongue to retain the thread when inserted. In a machine in which the threads pass down inside a hollow needlebar, twisting of the threads about one another is prevented by providing separate exit holes for them or separate guides close to a common exit hole ; in the latter case the guide for one of the threads may be dispensed with, the guides for the others being arranged to impose the minimum additional resistance. Provision may be made for more than two threads, particularly in a multi-needle machine : one end-holding clip may serve for all the threads.

A direct current amplifier comprises a first thermionic valve having anode, cathode and two control grids and arranged as a cathode follower, the cathode load consisting of the output load together with the anode cathode path of a second valve, both valves being driven by the signal but in opposite senses, the drive being applied to the first control grid of the first valve, the amplifier also including a further cathode follower driven by the signal and directly connected to the second control grid of the first valve. The Figure shows a D.C. amplifier supplying a capacitive load L, and comprising a double triode pre-amplifier V1 connected as a cathode coupled pair feeding the grid of the triode cathode follower V3 and the first control grid of a tetrode cathode follower output stage V4, the coupling resistor R5 being shunted by a capacitor C1 to ensure that the leading edge of the waveform is instantaneously passed to the grid. The first control grid of the tetrode V4 is fed from the anode of pentode V2 which acts as a constant current generator, the resistors R7, R8 clamping the grid. The second control grid of tetrode V4 is directly connected to the cathode of triode V3. The cathode of tetrode V4 is directly connected to the load L, to the anode of a second tetrode V5, and via capacitor Cf to the grid of the second stage of double triode V1 to provide negative feed-back. The tetrode V5 has the signal fed to its first control grid via resistor R13, the control grid also being supplied from the anode of pentode V6 acting as a constant current generator and a phase correction device as it is supplied with feed-back from the load via capacitor Cp#.
