Title: Steam-jet type fuel injection valve
Inventor: TATEISHI MATAJI
IPC: F02M43/04
Filed: 1978-01-05
Abstract: PURPOSE: To improve a state of combustion with an atomizing of the fuel oil promoted, by means of mixing a high pressure steam together with the fuel oil injected from a fuel valve.  
     CONSTITUTION: The water, pressurized by a high pressure water pump 21, is  heated by heaters 22, 23 being vaporized, and reaching a steam control valve 24.  The control valve 24 works in such manner that, with a fuel pressure going up and  the fuel being attempted to be jetted, the pressurized oil reach the control valve 24  through a control path 155, made branching from the half way of an oil passage  153, sliding a steam control valve unit 241, to open a steam passage 243, with a  high pressure and high temperature steam fed to a steam nozzle 245 to be jetted.  Simultaneously with the above operation, the high pressure fuel reaches a fuel  nozzle 151 being similarly jetted. A hole diameter of the steam nozzle 245 is made  larger than that of the fuel nozzle 151, and the steam is also jetted at the same time  with the fuel jetted. The fuel and the high pressure steam are injected while being  mixed together, with the fuel heated by the steam as well as an atomizing promoted  by the steam stream.

Title: Gasification reactor apparatus
Inventor: GEORGE MATON MAURICE EDWARD
IPC: C10J3/50
Filed: 1999-06-16
Abstract: A gasification reactor apparatus (10) comprising a gasification vessel (12), a gas-fired combustion chamber (70) and a combination fan and cyclone unit (20) in an upper part (12') of the vessel (12) with two functions: first, the fan (62, 64) impels incoming feedstock (14, 14') centrifugally into contact with the hot inside surface of the vessel to produce rapid onset of gasification. Second, the unit (20) exerts a cyclonic motion on the product gas causing outward separation of particulate matter from the gas, which passes to the outlet via a path through the middle of the vessel (12).

Abstract: 1,177,414. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1967 [16 Feb., 1966], No. 6931/67. Heading H1K. [Also in Division C7] A contact layer for a semi-conductor device is made by depositing on a substrate a coherent metal layer with semi-conductor inclusions capable of alloying with the metal from a fluid containing semi-conductor particles in suspension at a temperature below that at which said alloying occurs. The substrate may be of tungsten, molybdenum, nickel, nickel-iron or nickel-iron-cobalt alloy, ceramics such as alumina, or a semi-conductor body. Where self supporting layers are required use is made of a temporary substrate, e.g. of stainless steel or metallized glass, from which the layer can be peeled. The layer metal may be aluminium, gold, silver, cobalt or nickel or combinations thereof while the particles may consist of one or more of germanium, silicon, and gallium arsenide. Deposition of the metal may be effected by electroplating or electroless deposition from specified solutions. In a typical example boron doped silicon particles are incorporated in gold deposited on a gold plated boron-diffused area of an oxide coated N-type silicon body while antimony doped particles are incorporated in a similar fashion in a coating on the opposite face of the body. The assembly is completed by heating to above the eutectic temperature of gold and silicon. In another embodiment a nickel header to which a silicon diode, transistor or integrated circuit element is to be attached is electroplated in a gold potassium cyanide bath containing in suspension silicon particles of less than 5 Á diameter. Alternatively the header is electroless plated with nickel from a bath containing silicon particles.

Abstract: 355,164. Multiplex wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Jan. 5, 1931, No. 387. Convention date, Jan. 3, 1930. [Classes 40 (iii) and 40 (v).] In the simultaneous transmission of code and copying telegraphy over a single high-frequency channel, a carrier frequency modulated in accordance with the picture signals is alternated between two frequencies to form the code signals. The amplitude of the currents passed from a valve generator 1 to an amplifier 5, a modulator 6, and a transmitter 7 is controlled by a photo-electric cell 4 receiving light from the object, and the frequency of the generator is controlled by a signalling key 2 in series with a condenser 3 across the generator. Alternatively, the carrier frequency is produced by a shutter, perforated disc, Kerr cell, or other light relay in the path of the light scanning the object and controlled in accordance with the code signals to alternate the interruption frequency between two values. In the case of the rotating perforated disc, two rings of holes are provided, each comprising a different number. To prevent loss of code signals when there is no picture current, the code signals may be' transmitted a plurality of times ; or the carrier frequency is never reduced to zero, and at the receiver, Fig. 2 (not shown), a device in the copying telegraph channel has a threshold response, which is automatically varied according to the strength of the incoming high frequency energy.

Abstract: 1502741 Measuring velocity of mechanical vibrations BANYASZATI KUTATO INTEZET 7 Jan 1976 [9 Jan 1975] 00480/76 Heading G1G [Also in Division H4] Apparatus for measuring the velocity of low frequency mechanical vibrations comprises at least one spring means 1, a vibratable mass 2 secured to the spring means, at least two coils 3 mechanically coupled to the mass, a respective stationary core 4 of permanent magnetic material for each coil, one of the coils acting as a measuring coil N 1 and the other acting as a feedback coil N2, and a controllable current generator IV having a control input connected to one end of the measuring coil N 1 and an output connected to one end of the feedback coil, the connection polarities being such as to produce negative feedback. As shown in Fig. 2, the controllable current generator consists of an operational amplifier IC3 having a summing input connected via a resistor R4 to the measuring coil N1 and connected via a resistor R12 to the output of an integrator 11 whose input is also connected to the measuring coil. In this arrangement, a current flows through the feedback coil N2 which is the sum of a current component proportional to the velocity proportional signal from the coil N 1 and a current component proportional to the displacementproportional output signal of the integrator 11. These two current components produce a damping force component Fd proportional to the velocity of vibration as well as a force component Fw proportional to the coil displacement. With the appropriate choice of current flow directions, the component Fd constitutes negative feedback while the component Fw constitutes positive feedback. By a suitable change in the circuit gain, the amount of damping may be adjusted to an optional valve. The system has two outputs, Ua connected directly to the measuring coil N 1 and Us connected to the coil N1 via a pre-amplifier 1.
