Title: Improvements in or relating to apparatus for directly revealing the presence of objects which are invisible or obscure
IPC: G01C21/00
Filed: 1936-05-13
Abstract: 470,524. Viewing by infra-red rays. LIMELETTE, A. M.-F. P. DE. May 13, 1936, No. 13570. Convention date, May 15, 1935. [Classes 97 (i), 98 (i), and 98 (ii)] [Also in Group XL] Obscure objects are rendered visible by concentrating electromagnetic waves of a frequency less than that of luminous waves and proceeding from the object, upon the exploratory system of a television transmitter by means of a concave reflector placed at the point of observation, the modulated current being sent to a television receiver, A filter of manganese glass or of the substance known under the Registered Trade Mark " Bakelite" may be placed before the mirror. According to the Specification as open to inspection under Sect. 91, the mirror may concentrate the infra-red rays upon a screen such as a photographic plate which gives an image directly or after subsequent chemical treatment. The screen may comprise a dark background covered with a thin layer of gelatine-silver chloride or citrate with the addition of an infra-red sensitizer. On exposure the silver produced by the action of the light obscures the background thus producing a positive directly. Alternatively, iron salts producing a blue image may be employed. A screen giving an image after subsequent treatment may comprise a dark paper background covered with an opaque layer of bichromated gelatine or gum with a sensitizer and containing a pale pigment such as zinc white. Exposure to infra-red rays renders the layer insoluble so that on washing with water, the non-exposed parts dissolve revealing the dark base and producing a positive. The screen may also comprise a very thin sheet of platinum which is heated under the action of infra-red rays or may be of chlorophyl which becomes luminescent under infra-red light. This subject-matter does not appear in the Specification as accepted.

Patent GB-884305-A (GB)
Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: H03K3/26
Filed: 1958-05-02
Abstract: 884,305. Electric correspondence control systems. BOSCH G.m.b.H., ROBERT. May 2, 1958 [May 4, 1957], No. 14043/58. Class 40 (1). [Also in Groups XXVII and XL (c)] The rate of fuel supply to an I.C. engine is controlled by an electromagnetic valve fed with a series of pulses from a mono-stable relaxation oscillator, the duration of each pulse being determined by resistors sensitive to the temperature of the suction air, the atmospheric pressure, the speed of the engine, the temperature of the cooling water and the position of the air throttle. As shown (Fig. 1) fuel is supplied under pressure to an injection nozzle 10 and is released to the combustion chamber when a valve 11 is raised by energizing a solenoid 14, fed from an amplifier 15 whose input is a train of square pulses from a relaxation oscillator having two transistors T1, T2. When switch 25 is open the potentials at the base and emitter of transistor T2 are equal and the transistor is non-conducting, whereas transistor T1 is conducting. Switch 25 is closed for a short period in each revolution of cam 16, driven by the I.C. engine, and when closed reduces the potential at the base of transistor T2 to cause it to conduct, the collector current through resistors R2, R3, R4 in series producing a higher positive potential at the base of transistor T1 thereby blocking it. This reduces the voltage drop across resistor 21, and lowers the base potential of transistor T2 to maintain its conducting condition even after switch 25 is opened. Meanwhile the base potential of transistor T1 is raised by capacitor C discharging and at equal values of emitter and base potential transistor T1 reverts to its normal conducting condition and transistor T2 is again blocked. Thus a rectangular pulse 40 is produced at the input to amplifier 15, whose width is determined by the discharge rate of capacitor C, i.e. by the values of the series resistors R30, R31, R32, and also by the values of series resistors R2, R3, R4. Resistor R30 is adjusted in accordance with the position of a throttle in the inlet manifold, R31 by a centrifugal governor in accordance with engine speed, R32 is a thermistor located in the water cooling system, R2 is a fixed resistor, R3 is a thermistor in the inlet manifold whose resistance is indicative of the air flow into the combustion chamber and R4 is adjusted by a diaphragm sensitive to the atmospheric pressure. It is shown that resistors R30, R31, R32 have an additive effect and resistors R3, R4 have a multiplicative effect on the duration of the pulse T. Diodes D2, D3 are added to reduce the effect of temperature on germanium transistors T1, T2. In a modification (Fig. 4, not shown) a third transistor is connected across the capacitor C to linearize the discharge characteristic.

Title: Method of and apparatus for effecting thermal processes with finely granular or pulverulent substances
IPC: B01J8/18
Filed: 1950-06-06
Abstract: <PICT:0676391/III/1> A method of carrying out thermal processes as, for example, the hydrogenation of pulverulent solid bodies are present or are produced, or catalytic hydrogenation procsses as, for example, the hydrogenation of carbon monoxide to hydrocarbons &c. with the aid of nickel, cobalt or iron catalysts in a finely divided state, comprises passing the reacting gases with the fine material in suspension therein through a space into which or out of which heat is introduced or discharged by means of a moving solid heat carrier in the form of granules or lumps, the ratio of the grain size of the latter to the grain size of the suspended solid being at least 7 to 1 whereby the charged gases flow through the interstices between the granules or lumps of the heat carrier. The apparatus which in the form shown is adapted to the gasification of solid fuels (see Group XII) consists of a vertical shaft furnace 1 down through which moves a mass of ceramic bodies of uniform size for example 8, 12 or 25 mm. The bodies are extracted by a wheel 13 and elevated to a hopper 12 for recirculation.  In the upper part of the furance they are heated to 1200 DEG  to 1300 DEG C by combustion gases from a burner 15 and pass down into a chamber 3 into which the pulverulent material of grain size 0-1 mm. is introduced and is carried up through the interstices in the heated mass by gases flowing up from the lowermost zone of the shaft.  The gases discharge through ports 23 into a dust extractor 24 and thence to further purifying plant 26, 27 and 30. The process may be carried out at pressures of 20 atmospheres or over.  Where exothermic reactions are involved the heat carrier may be used to abstract heat from the reaction vessel.
