A suitable apparatus comprises concentric nozzles 1, 2, 3, the plastics melt being prepared duct is obtained as a powder. The gap widths of the nozzles 2, 3 may be adjusted by replaceable spacer rings 13, 14. There are heating means 6, 7 for the nozzles monitored by thermocouples 8, 9. The nozzles are aligned by centering collars having bores or slots, which may be inclined to impart a twist to the fluid passing through them; a baffle may be inserted at 100 to impart a like twist to the mixer gas streams. In other arrangements the melt may be extruded in the form of five strands through one or more bores (21, Figs. 3 and 4, not shown) into a stream of gas which impinges approximately perpendicularly upon them. The mixing nozzle may be situated at the in a single screw extruder and supplied through the nozzle 2, and atomizing gas (air, steam or inert gas) through nozzles 1 and 3. Intense sheer takes place in the zone 15 and the protop of a vessel (37, Fig. 5, not shown) in which the powder is cooled by injection of cold air (39) and the mixture passed to a separator (41) where the gas is allowed to escape.

A slide-rule for use in making calculations associated with protection from gamma radiation comprises two relatively movable members, the first of which 10 has a logarithmic scale 13 of the distance (d) from the source and the second of which 11 has a logarithmic dose-rate (R) scale 14, the logarithmic cycle of which is half that of the distance scale, the first member 10 also bearing, adjacent the dose-rate scale 14, a logarithmic source-strength (C) scale 15 having the same cycle as, but in opposition to, the dose-rate scale 14, and the second member 11 also bearing one or more scales 16 of the thickness (x) of the protective material. As shown, the second member 11 is an annular ring mounted in a disc constituting the first member, but a straight form is also described. A cursor 18 is provided. The sliderule is based on the equation : where A is the attenuation in the screening material and r is the gamma-ray output of the source material in milli-rontgens per hour per milli-curie at 1 metre.. Except for small thicknesses, A varies exponentially with x so that for a given source material (r constant), a scale of thickness may be provided which is linear except at the lower end. The scale is in fact determined experimentally. In the sliderule shown, four scales of thickness 16 are constructed for four different source materials where the screen material is concrete and a further set of four thickness scales are provided for lead screens. A dose-rate scale 14 is associated with each set of thickness scales. In the straight form, the two sets of thickness scales may be drawn on opposite sides of the slide.

Filed: 1973-05-01
Abstract: 1408832 Steam generation ROCKWELL INTERNATIONAL CORP 1 May 1973 [12 May 1972] 20674/73 Heading F4A In a method of generating steam, a fuel comprising no sulphur or nitrogen (e.g. liquid natural gas) is burnt in an oxidising atmosphere containing no nitrogen to produce heat which passes in heat exchange relationship with water in a heat exchanger 6 to convert the water into steam while maintaining the water isolated from the products of combustion. As shown in Fig. 1 vaporized liquid oxygen is fed through a line 20 from a pro-combustion chamber 48. Vaporized liquid methane natural gas is fed through a line 34 to a combustion chamber 4, the mixture being ignited by an ignitor either in the chamber 4 or at the point 58 in a gas passage 50, the burning gas being passed through a passage 50 of the heat exchanger 6. If necessary, additional oxygen is fed through a conduit 52 and manifold 56 into the combustion chamber. Steam is produced in the heat exchanger 6 by passing water through a line 61 to an exhaust condenser 70, a line 60 and an inlet manifold 62. The steam produced then passes out through outlet manifold 66 to a line 68 leading to a steam turbine or other suitable means. A temperature and a pressure controller are provided in the gas and oxygen supply line to control automatically the flow of fuel through the lines to the chamber 4 and heat exchanger 6. If desired, a secondary heat exchange fluid such as liquid metal, organic fluid, carbon dioxide, mercury &c. may be used as intermediate heat exchange fluids between the combustion gases and the water.

Title: Improvements in and relating to time measuring apparatus
IPC: G01S1/02
Filed: 1947-07-31
Abstract: 643,167. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. July 31, 1947, No. 20865. Convention date, Dec. 29, 1943. [Class 40 (vii)] In a pulse radar system a square waveform is developed comprising pulses commencing at the instant of pulse transmission and terminated on reception of the echo from the object, and means are provided to integrate these pulses to produce a wave having a peak magnitude corresponding to the range of the object, the amplitude of the peaks operating a range indicator. A transmitter 1 radiating pulses (Fig. 2, B) is associated with a directive antenna 2, 3 for transmission and reception which is also connected through T.R. box 4 to receiver 5. The received pulses from receiver 5 are fed to amplifiers 6 and 7 which are rendered effective for short consecutive periods of time (Fig. 2, D, E) by pulse generators 9 and 10. The time of occurrence of these periods is determined by feeding the output from amplifiers 6 and 7 respectively to integrators 13 and 14 to give a potential on conductors 17 and 18 dependent on the intensity of the echo pulse during the associated aperture period. The difference of the two voltages is fed from differential device 15 to delay multivibrator circuit 16 which is synchronized with the pulse transmitter over line 21 (Fig. 2, A) and controls the delay occurring therein before generator 10 is triggered. The finish of the pulse from generator 10 itself triggers generator 9. The arrangement is such (Fig. 2, F) that the gate pulses d and e applied to amplifiers 6 and 7 are automatically maintained in coincidence with the received pulse 32. The wave generated at the anode of valve 20 of the multivibrator (Fig. 2, C) has negative pulses of length determined by the time that elapses between the transmission of a pulse and the return of the echo signal and is fed through capacitor 35 to the distance measuring circuit. The negative pulses of wave C cause normally conductive valve 34 to be cut-off and condenser 38 to charge linearly (Fig. 2, G). The peak voltage on this condenser is measured by a valve voltmeter circuit including valves 40 and 43 and meter 44. The time measuring arrangements may be used in systems operating with compressional waves.
