Title: Improvements in or relating to devices for forming and projecting a line of light
IPC: G03B21/26
Filed: 1949-12-29
Abstract: 676,458. Optical-projection apparatus. BEST, C., and MOLINS MACHINE CO., Ltd. Dec. 28, 1950 [Dec. 29, 1949], No. 33241/49. Class 97 (i). [Also in Group XI] In a projector comprising an electric lamp with a straight filament and a lens system whereby an image of the filament is formed on a line of light, an image of which is formed at a desired position by lenses with or without prisms, the support for the lamp comprises a bracket rotatable about the optical axis of the projector and means for swinging the bracket about an axis transverse to the optical axis whereby the filament may be aligned with the slit and an image of the filament and of its real image formed by a concave reflector located behind the lamp, be brought to coincide on the slit. The projected beam may be used to facilitate the observation of the movements of instruments for example by reflection in a movable mirror, and may be applied to the device described in Specification 647,029, [Group XL (b)]. The apparatus described comprises a tube 1 containing a slit diaphragm 6 on which an image of the filament is formed by a condenser 5, and an image of which is projected by a lens 7 and prism 9. The condenser is carried by a tube 13 slidable within the tube 1 and carrying a flange 12 from which project studs 11, Fig. 7, supporting the concave reflector 4 adjustable axially by screwing into a plate 10. The mirror 4 and condenser 5 may thus slide axially together. Rotatably supported on the tube 1 is a ring 22, Fig. 3, supporting pivots 19, 20, Fig. 6, having an axis transverse to that of the tube 1. On these pivots is a stirrup-shaped member 18 to which is fixed a bar 17 having secured thereto the lamp 3. The ring 22 has an abutment 24 held against an adjusting screw 23. Thus, rotation of the lamp about the optical axis is effected by the screw 23, rotation about the transverse axis of the pivots 19, 20 is effected by a screw 25, Figs. 6, 7, on the member 18 engaging a plate 26 fixed to the tube 1, and a screw 21 effects transverse movement of the lamp along the axis of the pivots 19, 20. By these adjustments the images of the filament 3 are formed on the slit in the diaphragm 6. The prism 9 is held in place against a machined seating by tubes 31, 32, the former having diametrical lugs 34 engaging slots 33 in a sleeve 30 screwed into the tube 1 and pressing the prism against a gasket 29. A rubber dustexcluding washer 35 may be provided.

Title: Improvements in or relating to the cooling or drying of bulk material
Inventor: BRADFIELD KENNETH RUPERT
IPC: F26B17/26
Filed: 1954-11-18
Abstract: 768,284. Conditioning grain. SIZER, Ltd., R. Sept. 13, 1955 [Nov. 18, 1954], No.33410/54. Class 58. [Also in Groups XIII and XXX] In conditioning cereal grain, the grain is moved in a stream gradually up an inclined winding track, e.g. by vibration of the track, while a cooling or drying gas is passed over the grain transversely of the track. One or more spiral trays 21a, 21b are arranged inside a hollow easing or, as shown, outside a hollow casing 22 having apertures 28. Ambient air is drawn into the apertures after passing over the grain ascending the trays or hot air for drying is blown from them outwardly over it. The apparatus is located over an electrical or mechanical vibrator unit which acts on the apparatus directly or indirectly by hydraulic transmission. The top of the casing 22 is connected by a duct to a fan, Fig. 1 (not shown) for withdrawing air or for supplying heated air or air to be heated in the duct. A small branch from the duct may extract vapour or dust from a lower bowl 3 of the apparatus. Grain to be cooled passes along a shoot to a bowl 3 and passes up the helical trays which may have steps 29 at some points to re-arrange the grain. This agitating of the grain may also be achieved by surrounding the helical trays with another casing having apertures offset relatively to the apertures 28 to cause the air passing to or from the apertures to take a tortuous path. The trays may include an apertured duct for the flow of air and air may be drawn over one section of a tray and blown over the remainder. At the top of the apparatus, the grain is deflected from a platform 24 over a perforated surface 26 so that fines or dust fall into a chamber 26 and the grain then passes to an outlet 27 and by a shoot into a hopper for filling sacks.

Title: Improvements in or relating to the production of organic esters
Inventor: WILLIAMSON JOHN BENTLEY
IPC: C07C69/01
Filed: 1963-08-23
Abstract: Esters are obtained by treating an olefine of the formula R1(R2)C: CHR3, in which R1, R2 and R3 are hydrogen atoms or alkyl radicals, with a carboxylic acid and a gas containing molecular oxygen in the vapour phase in the presence of a catalyst containing a metal of the platinum group.  The catalyst may contain the metal in elementary form or in the form of a salt and may also contain promoters, e.g. sodium vanadate or molybdate, cobalt or copper acetate, vanadium pentoxide or phosphoric acid.  The catalyst is preferably supported, e.g. on active carbon, charcoal, pumice or silica gel. The reaction may also be promoted by including a small proportion of steam and (or) hydrogen chloride in the reaction mixture. The reaction may be effected at 50-250 DEG  C. and at atmospheric, reduced or raised pressure.  In a typical example, a mixture of ethylene and oxygen is passed through acetic acid at 55 DEG  C., to saturate the gas with acetic acid vapour, and the mixture is then passed at 150 DEG  C. over palladium supported on active carbon vinyl acetate and ethylidene diacetate are obtained. Propylene is also mentioned as a suitable olefine.

Title: Refractory oxide-alkaline earth carbonate supported catalyst
IPC: B01J23/00
Filed: 1961-09-19
Abstract: Reactions involving (1) removal of free oxygen or free hydrogen from gaseous mixtures, (2) removal of CO and CO2 from gaseous mixtures, and (3) production of H2O2 by autoxidation of hydroquinene are effected in the presence of a catalyst consisting of a support formed from an intimate non-glossy mixture of from 5-95% of a refractory oxide selected from Al2O3, SiO2, Clay, ZrO2 and TiO2\t and an alkaline earth metal carbonate and a catalytically active material consisting of a transition heavy metal or oxide of Group IB-VIIB and VIII of the Periodic Table.  With reference to reaction (1), less than 4% O2 can be removed from gaseous mixtures in one step while gaseous mixtures containing more than 4% O2 require recycling.  Thus, such catalysts have application in the manufacture of nitrogen from air. The optimum quantity of H2 which can be removed in one step is 8%.  In reaction (2) CO and CO2 are converted to CH4 and H2O if additionally the gaseous mixture contains H2. Example XII describes the preparation of H2O2 from autoxidation of 2-ethylanthraquinone.ALSO:A catalyst consists of a catalyst support formed from an intimate non-glossy mixture of 5-95% of a refractory oxide selected from Al2O3, SiO2, TiO2, ZrO2 and clay and an alkaline earth metal carbonate, and a catalytically active material consisting of a transition metal of Group Ib, IIb, IIIb, IVb, Vb, VIb, VIIb or VIII of the Periodic Table or an oxide thereof.

Title: Improvements in or relating to reversible gas-turbine plants
IPC: F01D1/30
Filed: 1953-12-03
Abstract: 749,557. Gas turbine plant. MASCHINENFABRIK AUGSBURGNURNBERG AKT.-GES. Dec. 3, 1953 [Dec. 3, 1952], No. 33669/53. Class 110(3) A gas turbine plant working on the open, semi-open or closed cycle comprizing a number of machine sets each consisting of a compressor driven by a turbine at least one of which supplies useful power has control members whereby the direction of rotation of the useful power machine set can be reversed by supplying air to the turbine exhaust and the heated working fluid to the compressor discharge. The low pressure axial flow compressor 1 driven by a low pressure turbine 2 discharges through an intercooler 3 and a control member 4 during forward running, to the intake of a radial outward flow compressor 5. The compressor 5 discharges through a second control member 6 to the exhaust gas heat exchanger 7 and combustion chamber 8 which discharges through the control member 6 to the high pressure radial inward flow turbine 9 which drives the compressor 5 and through gearing 10 a propeller 11. The exhaust from the turbine 9 passes through the control member 4 to the reheat chamber 13 and low pressure turbine 2 which exhausts through the heat-exchanger 7. To reverse the direction of rotation of the propeller 11, the control members 4, 6 are moved to the position shown in dotted lines. The air from the compressor 5 then passes to the exhaust of the turbine 9 which then acts as a compressor and discharges through the control member 6 to the heat exchanger 7 and combustion chamber 8. The combustion chamber 8 feeds through the control member 6 working medium to the discharge of the compressor 5 which then acts as a turbine and discharges to the reheat chamber 13 as described above. A blow-off valve 16 is provided to prevent unstable operation of the compressors during reversing. A starting machine 5 may be used to facilitate reversing by being operative for a short time. Axial flow machines may be used for the compressor 5 and turbine 9. Radial flow machines may be used for the compressor 1 and turbine 2.

Filed: 1971-07-19
Abstract: 1355684 Cameras with flash contacts ASAHI KOGAKU KOGYO KK 19 July 1971 [3 Aug 1970(2)] 33823/71 Heading G2X A camera has an accessory mounting shoe 1, an electrical contact being closed only when an accessory is fitted into the shoe. As shown, the shoe has a synchronizer contact 3 connected via a switch SW4 and a two-way selector switch SW3. As switch SW3 is moved to the right or the left, either synchro terminal seat T 2  or T 1  connects a flash device to the camera, in the one case an electronic flash, in the other a flash bulb. Alternatively, the flash device may connect directly to contact 3. The arrangement of Fig.3 represents the switch SW4. A leaf-spring 6 is separated by an insulating collar 10 from a contact piece 8, spring 6 being connected to contact 3. An insulating pin 11 attached to spring 6 extends through the insulating base 4, its upper end being just below a bent spring member 2' . When an accessory is attached to the camera, a leg portion slides into the space between the shoe 1 and member 2', which is bent at one end to act as a stop. As the accessory slides in, it pushes the spring member 2' downwards, which in turn pushes the pin 11 downwards, so that the contact 7 at the end of leaf-spring 6 makes electrical connection with the contact piece 8. Since switch SW4 is open until an accessory is mounted in the shoe, electric shock hazard is reduced.

Abstract: 1,198,517. Digital position measuring devices. KERN & CO. A.G. 24 July, 1967 [23 July, 1966], No. 33882/67. Heading G4H. In an optical goniometer the angle is set on a graduated circular plate 14, Fig. 1, carrying a coded scale 14<SP>1</SP>, Fig. 3, and a grating 14<SP>11</SP>. Light is projected through the coded scale on to photo-cells to give a coarse reading of the angle. A fine reading is given by a coded disc 23 which is rotated by a motor 20 through gear 19. This carries a plane parallel sheet of glass 17 which serves to deflect the image of a grating 10 which is focused upon the grating of plate 14, transmitted light falling on photo-cell 16. At the instant of coincidence a signal is given which causes the values of plate 14 and disc 23 to be stored or recorded on punched tape or card or on magnetic tape. The motor is controlled automatically, when a reading is to be taken, to drive the fine reading disc 23 and the deflecting plate 17 and to return them to the starting position after the recording has been taken. In another form, Fig. 5, the angle is set on a circular plate 40 having coded tracks to be read by photo-cells 57 and a fine grating round the circumference, the image of which is projected by lamp 41 via prism 43, lens 44, deflector sheet 51 and prism 45 on to the grating on the other side of the disc. The deflector 51 is turned by a motor as before, and a disc 50 turning with it carries a series of fine lines sensed by photo-cell 60 to produce incremental pulses. These are counted to indicate the angle through which the sheet 51 has turned, and a recording is made when photo-cell 47 indicates that the image from the left-hand side of plate 40 coincides with the grating of the right-hand side. A start mark on the disc 50 is sensed by photo-cell 62.
