Abstract: 799,380. Charging particles in a gas stream. JASCHIN, G. MESSEN-, [trading as JASCHIN, G. A. MESSEN- [Firm of]]. March 27, 1956 [April 1, 1955], No. 9562/56. Class 98(1) Apparatus for the electric charging of matter suspended in a gas stream consists of a conductive support carrying at least one radioactive source emitting a cone of radiation in the direction of the gas stream, at least one electrode beyond the effective range of the radiation, and means for producing a high potential difference between the conductive support and the electrode. As shown in Fig. 1, a source 3 of alpha particles is formed as a layer on a conductive support 4, so that it produces a cone of radiation 5 producing maximum radiation at a zone 6 just before the end of the range of the particles. The source 3 and support 4 are mounted within an insulated tube 1 through which gas, laden with particles to be charged, passes in the direction of the arrow W. A cylindrical electrode 2 within tube 1 is maintained at a high potential with respect to the conductive support 4 by a battery 7. The particles carried by the gas receive a charge of the same sign as the support 4. The source 3 may be replaced by a source of beta particles. Mesh electrodes may be mounted across tube 1 upstream and downstream of the electrode 2. Several sources of radiation may be mounted in a plane normal to the tube axis. The source may have a wire mesh on the upstream side, electrically connected to the support 4, and may be backed by a body shaped to produce turbulence near the source, to prevent matter from being deposited on it. The tube should be wide enough to embrace the cone of radiation 5 at the zone 6, and may be narrowed upstream of the area where the particles are charged.

Abstract: 1,038,615. Cooling systems for electrical apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 7, 1984 [March 11, 1963], No. 9573/63. Heading F4U. In a cooling system for a source of radio frequency power such as a magnetron 9 supplying energy to, for example, a linear accelerator, water is circulated from a temperature stabilized supply unit 23 to maintain the magnetron at a steady working temperature and, so that the magnetron may start at substantially the same temperature to deliver energy immediately at the correct frequency, the system includes means whereby the magnetron is held at its operating temperature under standby conditions. In the form shown a tank 27 is interposed in the return line 25 from the unit 23 and is provided with an electric immersion heater 31 the supply switch of which is coupled to the magnetron switch so that when one is open the other is closed. Thus under standby conditions water warmed to a temperature which maintains the magnetron at its working temperature circulates therethrough. In a modification, Fig. 3 (not shown) the standby flow and hence the heating current required is reduced by closing a valve inserted in line 25 and allowing a suitably restricted water flow to by-pass the valve.

Abstract: 423,139. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. March 28, 1934, No. 9710. Convention date, April 1, 1933. [Class 38 (ii)] Relates to an arrangement employing a valve having a thermionic cathode for controlling the supply of energy from a source of current to a load circuit and consists in the provision of means for delaying the application of load to the valve until the cathode has heated to the operating temperature and also for preventing interruption of the flow of current through the valve upon a momentary failure of the source, for an interval greater than that of the failure of the source. This is to avoid the undesirable prolonged breaking of the load circuit as a result of a momentary failure of the source. The anode circuits of valves 15 operating in a rectifier arrangement are completed by means of a switch 16 having an operating solenoid 17. Closure of the switch 20 energizes the filaments of the valves 15, and the operating winding of a time delay closing relay 21, which, after a time interval to allow the filaments to heat up, completes the circuit of a relay 23 which energizes the operating circuit of the switch 16. This relay 23 closes immediately, but has a time delay opening so that it remains closed during a momentary failure of the supply. To prevent delay in the re-energization of the relay 23, due to the relay 21 opening, the relay 23 is provided with holding contacts 24.

Abstract: PROBLEM TO BE SOLVED: To keep tracking easily while enhancing the identification accuracy of target by solving the equation of motion of a target and estimating the acceleration of target. SOLUTION: An acceleration estimating section 21 introduces a dynamic model to a target and sets an equation of motion thereof. In the equation, thrust, lift coefficient and bank angle are handled as probability variables and the path angle and speed are determined from the history of movement by extrapolation. Other constant parameters are provided provided from an aerodynamic parameter data base 20 using the identification results from an identification processing section 23 as a retrieving means. More specifically, acceleration is estimated while correcting the equation of motion and the estimation results are delivered to a tracking processing section 22. The processing section 22 predicts the target position at next sampling timing based on a target position received from a target detection circuit 4 while taking account of an estimated 21 acceleration and tracks the target.  The processing section 23 calculates the motion characteristics from a motion data based on the tracking results from processing 22 and specifies an aircraft having closest pattern by retrieving a motion characteristics data memory.
