Title: Irradiation of an object with charged particles
IPC: A61N5/10
Filed: 1974-02-11
Abstract: 1413098 Charged particle exposure monitor SIEMENS AG 11 Feb 1974 [10 Feb 1973]  06196/74 Heading G1A In apparatus for irradiating an object with charged particles, in particular, electrons, in which a diffuser is arranged in the path of the beam issuing from the beam generator for spreading or broadening the beam so that the particles are distributed uniformly over a wider cross-sectional area, a plurality of detectors are provided to monitor different cross-section portions and detect non- uniformity of the intensity distribution. In Fig. 1, a betatron is used to produce a stripshaped beam 7 of electrons of a particular selected energy. After passage through aperture 12 in protection screen 11, the beam is spread by diffusing foil 8 or 9 mounted on a wheel member 10 and selected in correspondence with the selected electron beam energy. The broadened beam crosssection is then defined by adjustable diaphragm 13, to provide the cross-sectional area 14, shown dotted in Fig.2. A detector arrangement 14 is positioned in the diverging beam 15 and comprises a central strip-shaped detector 16 and two square-shaped detectors 17, 18. The detectors are connected to respective meters. Detector 16 is arranged to actuate a switch-off unit when a pre-set dose is received, which must be due to the absence of the diffusing foil in the correct position, or merely the end of a normal correct exposure. Detectors 17, 18 give equal measurements during correct operation, but if inhomogeneous electron beam density occurs e.g. due to incorrect foil or diaphragm positioning, a differential amplifier produces an output to an optical alarm. Besides this, the output of detector 16 should bear a particular ratio with respect to the outputs from detectors 17, 18, when a particular diffusing foil is used. If the ratio deviates from this predetermined value, a further optical alarm is actuated. The beam generator may also be switched off. Instead of a betatron, a linear accelerator may be used, Fig.4 (not shown).

Patent GB-450264-A (GB)
Title: Improvements in or relating to the production of colloidal dispersions
IPC: B01J13/00
Filed: 1935-03-01
Abstract: Colloidal dispersions are obtained by subjecting the material to be dispersed to a high potential with respect to a dispersion medium with which it is immiscible, the dispersion medium being separated from the material by an insulating partition having one or more minute orifices in it.  Preferably the material is in the liquid state, e.g. molten metal or liquid alloy, and forms one electrode, a second electrode being immersed in the dispersion medium.  The insulating partition may consist of a thin membrane of high dielectric strength, e.g. a cellulose acetate film, and may be punctured by a needle or by the application of a sufficiently high potential, or it may comprise a tube containing the material to be dispersed, provided at one end with a capillary tube which dips below the surface of the dispersion medium. According to an example, mercury is introduced into a cell and connected to a source of current.  The surface is covered with a thin film of the dispersion medium, e.g. a semi-conducting electrolyte such as tricresylphosphate, and a cup-shaped partition of cellulose acetate and containing the main bulk of the dispersion medium is lowered into contact with the mercury.  A second electrode is provided in the cup, and the electrodes are connected to a direct or alternating current supply of high voltage.  A voltage of about 10,000 volts suffices to puncture a cellulose acetate partition of ,003 inches thickness, and thereafter the voltage may be reduced to 3000.

Abstract: 1374103 Automatic control of aircraft SPERRY RAND CORP 30 Nov 1971 [10 Dec 1970] 06515/74 Divided out of 1374101 Heading G3R [Also in Division G4] The computer elements shown in Fig.10 are intended to produce a signal W corresponding to an aircraft flight control parameter (weight) free from dynamic errors which arise due to wind effects and other transients in the derived inputs. The uncorrected signal appears at the output of 57 and is filtered at 59 and integrated at 60, the output of which is said to be the desired, corrected signal. This is fed back as shown for subtraction at 58 from the uncorrected signal, the output of 58 thus being the dynamic weight errors signal only. This is in turn fed back on line 63 to correct that portion of the computer 49' which calculates the actual coefficient of lift C/L, and this is the subject of the main claim. The amount of feedback used is determined by KW and is set to allow for slow changes e.g. due to fuel consumption. The signal W is the weight supported by the wings; during take off this varies rapidly so at this time an alternative filter 59', having a short time constant, is switched in. The switch, 204, is controlled by a lift off detector 26 which responds to the tilt angle #, measured by a gyroscope. The invention claimed is also applicable to an angle of attack computer which comprises means 45, 46 reponsive to the values shown on the left of Fig 8 for providing an initial angle of attack signal sin α that includes dynamic error components which are then eliminated as shown in Fig.9 by feeding back a signal on line 63 corresponding to weight error, which is derived as described above. The invention is used with other computer circuits for manual or automatic control of airspeed and pitch angle of an aircraft during takeoff and landing. Associated features from the subject of the parent and other divisional applications.

Title: Improvements in the manufacture of styrene and derivatives of styrene
IPC: C07C17/35
Filed: 1945-03-15
Abstract: Styrene or its substitution derivatives are prepared by heating phenyl methyl carbinol or a substitution derivative thereof in vapour phase under a pressure below 300 mm. in contact with a dehydration catalyst.  Substitution derivatives include alkyl, aryl or halogen, nuclear or side chain derivatives, for example 4-chlorstyrene, 4-chlor-b -chlorstyrene, 4 - brom - b  - methylstyrene, 4 - ethylstyrene, 2-, 3- and 4-methylstyrenes, and a -methylstyrene.  For phenyl methyl carbinol, pressure is preferably below 100, especially 30-70 mm., and temperature above 300 DEG , especially 350-450 DEG  C. Preferred conditions are about 50 mm. and 380-420 DEG  C.  Activated alumina, especially in massive form, for example as pellets, is the preferred catalyst. Others include other metal oxides, and phosphoric acid or a phosphate on a carrier.  Catalytic activity is restored as required by heating to 400-450 DEG  C. in air.  Hydroquinone or other polymerization inhibitor, for example in an amount of 0.1 per cent by weight, may be mixed with the phenyl methyl carbinol.  In one example, phenyl methyl carbinol, which may contain hydroquinone, is treated at 400 DEG  C. and 50 mm. with activated alumina, the products condensed and stratified, and the upper layer distilled at 50 mm. in presence of hydroquinone.  The 4-chlor derivative is similarly dehydrated at about 45 mm.

Filed: 1948-03-02
Abstract: 650,173. Modifying surface reflection. LIBBEY-OWENS-FORD GLASS CO. March 2, 1948, No. 6580. Convention date, Nov. 3, 1947. [Class 97 (i)] [Also in Groups II and XV] A support is coated with a solid metallic oxide by providing on a heated body an oxide of aluminium, titanium, chromium, tin, zirconium, antimony, iron, tantalum, tungsten or manganese, heating the body in vacuo to deposit an oxide film on the support, and then heating the coated support in an atmosphere containing oxygen so as to oxidize the oxide of lower oxidation state on the support to form a coating of a highly oxidized solid metallic oxide. The coating may be protective, reflection reducing or such as to form a semi-transparent or coloured mirror, and the oxidation step may be effected by heating with a flame or in an oven, if necessary under pressure. Suitable supports are glass, porcelain, tile, ceramic, earthenware, aluminium silicate, mica or silica. A reflection reducing coating may consist of an oxide layer, a layer of beryllium oxide or magnesium fluoride followed by a further oxide layer. For coating with aluminium oxide the heated substance may be a spinel, i.e. magnesium or calcium aluminate or may be aluminium trioxide, hydroxide, nitrate, formate, acetate or lactate. Other substances which give the corresponding oxides on heating are antimony trioxide, sulphate or tartrate, tin oxide or dioxide, tungsten trioxide, chromium sesquioxide with, if desired, tantalum pentaoxide, or zirconium, titanium or manganese dioxide. The evaporation apparatus shown in Fig. 1 comprises a support 13 for the glass or other plate 14 to be coated and thermal evaporation means 15, 16 of tungsten or tantalum separated by a sliding screen 19. In an example described a glass plate is first coated with a mirror surface of aluminium or chromium by heating the coil 15. The screen 19 is then slid away and a coating of chromium oxide applied by heating the coil 16 which contains chromium sesquioxide which may be mixed with tantalum pentaoxide. Subsequent heating converts the oxide coating to a higher oxide having improved properties.
