Title: Method of reducing iron ores in rotary furnaces with fluid reducing agents
IPC: C21B13/00
Filed: 1962-01-05
Abstract: <PICT:0984696/C6-C7/1> A method of reducing iron ore in a rotary furnace with a fluid reducing agent comprises grinding the ore finely enough to produce a fluidized bed and injecting the reducing fluid into the bed.  As shown, the reducing fluid may be introduced through a pipe 4 arranged parallel to the longitudinal axis of the rotary furnace 1 and injected through a nozzle 5 through the surface of, and into, the bed.  In one modification the nozzle 5 penetrates the surface of the bed, Fig. 2 (not shown), in another, Fig. 3 (not shown), the pipe 4 and nozzles 5 are embedded in the charge, and in a further modification the fluid may be introduced into the bed through the furnace wall.  The reducing fluid may comprise hydrocarbons and small quantities of oxidizing gas, e.g. air, oxygen, or water vapour, or may be an oil which desirably may be cracked inside the bed.

Abstract: 560,737. Testing flash lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 14, 1943, No. 705. Convention date, Jan. 21, 1942. [Class 9 (ii)] A flash lamp is provided with an electrically conducting member or electrode on the inner surface of the envelope at a point remote from the flashing element and between the points where high-frequency discharge occurs inside the bulb during test for air to facilitate such discharge. The invention is especially useful in flash lamps wherein the source of actinic radiation is formed by one or more beads or compact masses of fulminating material 19 disposed around the bridge wire 18 and the ends of the lead wires 17 as described in Specification 548,297. The electrode may take the form of a metal filament or wire or cross wires 20 supported on the inner surface of the bulb 10 or a coating of aluminium or bronze paint or carbon painted on the inner surface of the bulb. During test the bulb is placed in a glass bath 22 containing a mercury terminal 25 on which the part of the bulb adjacent to the electrode rests, and an insulating liquid 29 such as trichlorethylene or carbon tetrachloride on which rests a layer of conducting liquid 30 such as water, the liquids being immiscible. The mercury terminal is connected to one terminal of the secondary of a Tesla coil 28 so that on closing the primary 32 thereof, a discharge 34 occurs in the bulb between the electrode 20 and the envelope on each side.

Abstract: 796,587. Ice making. GENERAL MOTORS CORPORATION. Jan. 10, 1956 [Jan. 27, 1955; March 14, 1955], No. 812/56. Class 29 An iceblock release apparatus for a domestic refrigerator comprises a flexible tray and grid assembly 24 the grid being attached to the tray and having a plurality of rigid walls movable relatively to the tray, a support for holding the assembly in inverted position so that loosened ice blocks can fall therefrom, and means for flexing the inverted tray to cause relative movement between the walls and the tray. The flexible tray 25 is of aluminium and has a grid of rigid transverse members freely pivoted to the side walls of the tray by lug-amd-slot connections and joined together by a longitudinal wall, A rim 26 depends from the tray and at one end carries a handle 31 and at the other end a rod having outwardly projecting studs 34. The support consists of two elongated guide supports of moulded plastic, fixed to an inverted U-shaped member 37 and having each at their front end an integral inwardly projecting boss 35. Each guide support has a slot 43, 44 respectively, in plan as shown in Fig. 3 into which the studs 34 engage. In use a tray assembly 24 containing ice blocks is inverted and the projections 34 engaged in the slots 43, 44. The side edges of the tray are abutted by the bosses 35 and the base is held by a rod 39 extending between the guide supports 36 and acting as a roller bearing. On pushing the tray assembly in between the guide supports the divergence of the paths of the slots causes a flexing of the assembly and consequently ejection of the ice blocks. The release apparatus is placed in the freezing chamber of the refrigerator and the member 37 forms the lowest shelf of the freezing tray shelves. In a modification Figs. 14, 15 (not shown) the paths of the slots may be designed to cause a sudden inflexing of the assembly thus to release the ice blocks more efficiently.

The ball 8a is thermocompression welded to the semi-conductor 17 by a tool 6 maintained at a constant temperature by heating coils 10. After unclamping the wire, the tool 6 is moved and the side of the wire 8 welded to the lug 20, whereupon the wire 8 is reclamped and an arm carrying the tool 6 and clamps 11a, 11b moved upwardly to cause the wire to break at a notch formed during the previous welding operation. The operation is then repeated to connect a wire between the semi-conductor 17 and the lug 19.

Title: Selective driving circuit
Inventor: HORIUCHI MICHIHIKO
IPC: G03G15/05
Filed: 1983-01-06
Abstract: PURPOSE:To realize the high-speed switching operation of a transistor (TR) which performs a switching operation by adding a capacitor stored with the driving energy of the transistor (TR) to an electrostatic recording device which uses a multistylus electrode. CONSTITUTION:When a TR1 is on, a current is supplied from an R1 to the base of a TR2, which is then turned off to obtain a low-impedance output. When the TR1 turns off, the charging of the output electrostatic capacity of the TR1 is carried out principally by the current which flows through a switching diode D2 and a resistance R2 from a V2, but when the TR2 is cut off, the charging is performed principally by te constant current which flows through the R2 from the emitter of the TR2. Further, a C1 is connected in parallel to a Zener diode D1 to supply stably the base current for turning on the TR2. Consequently, the switching operation of the TR2 is performed at a high speed and does not depend upon the characteristics of the D1.

Abstract: PURPOSE:To avoid the influence of a single failure generated in any one sequence of a triple self-holding circuit by constituting the self-holding signal of each self-holding circuit of a 2/3 logical signal between the output signals of corresponding other two self-holding circuits and the output signal of the self-holding circuit concerned. CONSTITUTION:When it is supposed that an optional one power source, e.g. 11a, out of power sources 11a-11c is braked during the excitement of all relays 11a-11c, relays 14a, 15a are unexcited, but the states of other relays and an output signal to a controlled system 30 are not changed. When the power source 11a is restored, relay contacts 14b, 14c are continuously closed, so that the relay 15a is excited and a sequence circuit 10a is restored to the original state simultaneously with the restoration of the power source 11a without the execution of any operation. When the power source 11b or 11c is braked, the same rule is applied.

Filed: 1984-01-06
Abstract: PURPOSE:To attain lighting for the confirmation of a condenser microphone in operation by utilizing a voltage drop being a characteristic of a light emitting diode and using the voltage as the impression voltage for the condenser microphone. CONSTITUTION:In turning on a switch 103, a current flows with the relation of a voltage appearing across a resistor 201 and a power terminal 10 of a device 1a. In this case, a resistance value of the resistor 201 is set so that the rated current flows to the light emitting diode 110. Since a voltage (nearly 1.7V) required between an impression voltage terminal 20 and an earth terminal 21 of the condenser microphone 2 is generated across the light emitting diode 110, the voltage is impressed. Then an output being a voltage proportional to the condenser microphone 2 is obtained from the microphone output terminal 22 of the condenser microphone 2, and only the AC component is inputted to the microphone input terminal 12 of the device 1a by a coupling capacitor 104. The light emitting diode 110 is flickered by ON/OFF of the switch 103 and the operator can recognize easily that the condenser microphone 2 is in operation when the light emitting diode 110 is lighted.
