Title: Improvements in or relating to the manufacture of strontium fluoride optical elements
IPC: B01J3/06
Filed: 1962-12-12
Abstract: <PICT:1018560/C1/1> <PICT:1018560/C1/2> Dense polycrystalline strontium fluoride is prepared by moulding pure microcrystalline strontium fluoride powder at a pressure between 25,000 and 50,000 p.p.s.i. at 800 DEG  to 900 DEG  C. until homogeneous.  The fluoride is moulded for 20 minutes in a chamber either containing an inert atmosphere or preferably evacuated, after which it is allowed to cool in an inert atmosphere, e.g. argon.  The density of the moulded strontium flouride is at least 99% of the theoretical.  Suitable apparatus is shown in Fig. 1, where the strontium fluoride 10 is moulded in cylinder 12 by plunger 17 having head 8, which may be attached to an hydraulic press.  Cylinder 12 and base block 13 are provided with thermocouples 28 and 31 respectively. Cylindrical refractory casing 21 and heating unit 14 surround mould 12.  Outer cylinder 29, with cooling coils 25, encloses chamber 30 which may be evacuated by means of conduit 24.  Fig. 2 shows induction heating coils 64, water pipe 70 connected to cylindrical water cooling chamber 63, vacuum conduit 65 and vacuum release conduit 66. Reference is directed by the Comptroller to Specification 913,175.

Title: Improvements in or relating to apparatus for taking impressions of surface patterns
Inventor: EDER WOLFGANG ERNST
IPC: B44B1/00
Filed: 1967-10-18
Abstract: 1,243,505. Embossing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 2 Oct., 1968 [18 Oct., 1967], No. 47415/67. Heading B6J. [Also in Divisions G1 and H2] A method of obtaining a replica of a pattern on a surface 111 comprises measuring the temperature of the surface, coating a platen with a material whose melting point is higher than the measured surface temperature, heating the platen to a temperature close to the melting point of the material and projecting the platen against the surface so that the material receives a replica of the pattern and hardens. The method may be used for analysing structural strains by cutting spiral grooves in the surface of a member to be strained and examining the distortions of the spiral by forming a replica of the grooved surface using the platen gun 11. The platen comprises a circular plate with a central stem and is mounted in a heating former positioned in a guard 18. The platen is made, for example, of mild steel, aluminium or brass and its face is coated with a thin film of lead-tin solder before applying an alloy layer, a range of alloy layers being used in view of the range of surface temperatures encountered. Three support legs, two of which 15, 17 are shown, surrounded the guard 18 and locate the gun against the surface, the leg 17 incorporating a temperature sensing element such as a thermistor RT1. A further thermistor RT2 is incorporated in the platen heating former and indicates the platen temperature. Power for the gun is supplied by a pack of nickel-cadmium accumulators connected to a socket 31. A switch 33 having a zero and three further positions is mounted on the housing 12 of the gun. In its first position contacts 51 are closed to enable the accumulator voltage to be checked on a voltmeter 30. In its second position contacts 52 are closed and the gun is held against the surface. A knob 34, which is calibrated in degrees Centigrade and which operates a potentiometer V1 in a Wheatstone bridge 41, is rotated to balance the bridge as indicated by the voltmeter 30 and to thereby measure the surface temperature. A suitable platen is then selected, a knob 35 controlling a potentiometer V3 is set to a suitable platen temperature and the switch 33 is turned to its third position thus closing contacts 53. A manual switch 32 is also closed by pressing a button 14 or 36 to commence heating of the platen by coils H1, H2. A lamp 29 is switched on whilst the heating takes place but when the preset platen temperature is reached the main heating current is automatically switched off and a thyristor TC is automatically switched on to energize a solenoid which actuates a plunger to strike the stem of the platen, thus ejecting the platen towards the surface 111. The switch 32 is then opened to switch off the thyristor and a light 28 glows until the thermistor RT2 cools sufficiently to reset the circuit.

Abstract: 1349223 Ventilating vehicles E RAPPOLD 16 Oct 1972 [15 Oct 1971 7 July 1972] 47629/72 Heading F4V In a ventilation system for the patient's compartment 2 of an ambulance, atmospheric air is drawn into the compartment through a ventilator 5 which has a germ filter 6. The filter has an insert 7 arranged in the circulation system of a disinfection fluid, e.g. formalin. Air is removed from the compartment through a socket 12 by a fan 16. Behind the fan 16 is a combustion chamber 14, and air sterilized in this chamber is discharged to atmosphere through an exhaust pipe 18. A non-return valve 17 is provided between the socket 12 and the fan 16 to prevent air from the combustion chamber returning to the compartment 2. In another embodiment (not shown) ultra-violet radiators are provided in front of the combustion chamber.
Patent GB-477012-A (GB)
Abstract: 477,012. Gyroscopic apparatus. MOSS, D. G. K., and PEIRCE, H. C., (trading as MECHANISM). June 19, 1936, No. 17109. [Class 97 (iii)] The spin axis of a gyroscope having a scale ring carried by the outer gimbal. is reset in azimuth by precession caused by the creation by means of air jets of a couple between the inner and outer gimbals. In the form shown, a couple around the horizontal axis on which the inner gimbal or rotor casing pivots in the outer vertical gimbal is created by the impingement of an air jet from one or other of the nozzles 51, 53, carried by the vertical gimbal 3 on a series of vanes 66 mounted on a ring 65 carried by the rotor casing. Air for driving the rotor 1 is drawn through channel 8, through the central part of the lower bearing of the vertical ring 3, through a channel 18 in the gimbal 3 and hollow trunnion 25 of the rotor casing 2 to the nozzle 27. The air escapes from the casing 2 through a channel 28 in the trunnion 29 and a pair of oppositely directed air jet orifices in a tubular extension 34 surrounding the trunnion 29, a semicircular extension 35 of which differentially obscures the orifices causing torques which keep the rotor spin axis normal to the plane of the ring 3. Alternatively, the spin axis may be brought to the true horizontal by a pair of oppositely directed air jets issuing from a small chamber in the rotor casing, a rolling ball enclosed in the chamber serving to control the jets. Air is supplied to the jet 51 through channels 50, 48, 46 and a mushroom valve 54, Fig. 5, and to the jet 53 through channels 52, 49, 47 and a mushroom valve 55. One or other of the valves 54, 55 may be opened against the tension of a spring 58 to initiate the precession in one or other direction by a member 59 which may be rocked about its pivot 60 so as to contact and press in one or other of the valve stems 56, 57 by operation of a control knob at the front of the instrument casing. In a modification, valves controlling the supply of air to the jets 51, 53 are operated by a ring which is caused to slide up or down around the lower trunnion of the vertical ring by a bifurcated lever adapted to be moved by a cam on the spindle of the control knob.

Abstract: 1,092,735. Photographic processing apparatus. EASTMAN KODAK CO. Nov. 26, 1964 [Nov.29, 1963], No.48098/64. Heading G2A. [Also in Division G1 ] In order to maintain a required relationship between the rate at which a shaft 16 drives a film 32 through a tank 35 of treatment medium and the temperature of the medium, a crank 30 is turned so as to maintain a constant reading of a scale 18 against a pointer 21. The scale 18 is turned against the action of an eccentric weight 20 by a coupling fluid 11, whose viscosity bears the same relationship to temperature is that required above. Thus the treatment will be unaffected by changes of temperature if a constant reading is maintained by adjusting the speed of rotation of the shaft 16 either visually or automatically in accordance with sensed error signals. The range can be increased by providing another weight 22 to be picked up after 90 degrees of scale rotation. The coupling fluid 11 may be a mixture of oil and kerosene and is contained in a transparent casing 10 on the shaft 16. If the treatment fluid is opaque a soft wiper may be fitted near the pointer 21 to clear that region of the casing. The scale 18 may be carried by a wheel with spokes acting as vanes.
