Title: Improvements in epicyclic gearing
IPC: F16H63/30
Filed: 1935-11-23
Abstract: 466,353. Epicyclic variable speed gearing. LUTZ, E. C., and WALL, A. W. Nov. 23, 1935, No. 32521. [Class 80 (ii)] Relates to epicyclic gearing of the type in which the sun wheel and planet carrier form the driving and driven members, and the gearing is put into operation by contracting a brake band disposed around the periphery of the annulus. According to the invention, the brake band comprises a relatively stiff C- shaped member, one end of which is secured directly to the gear housing, while the other is acted on by a presser member sliding through the housing wall. As shown, the crankshaft 5 is supported in a sleeve 11 having an enlargement clamped to the crankcase 8. The shaft 5 carries a sun 10 engaging planets 22 rigid with planets 23 supported in a carrier 16, 21 supported by a bearing 18 on the sleeve 11 and carrying a gear 24 which engages a gear 25 on the driven shaft 26. The planets 22, 23 engage respectively annuli 27, 28 adapted to be arrested alternatively by brake-bands 29, 30. Each band is secured at one end to the casing by a screw 55, while its other end has an abutment 54 acted on by a plunger 53. When two bands are employed, the plungers 53 may be brought into action by springs permitted to operate alternatively by a rocking lever. If more than two bands are used, the plungers may be operated by a multiple camshaft. In a modification for a motor wheel, the driving-shaft of the gear is geared to the crankshaft and carried in an extension of the crank-case on which the planet carrier and the vehicle wheel attached thereto are journalled. Instead of the epicyclic train shown, two simple trains in parallel may be employed. The driven gear 24 may be connected to an ordinary 3 or 4-speed gear-box. Each annulus 27, 28 may be located against endwise movement by shoulders or rings in the casing, which rings may also centralize the annuli. The driving shaft may be axially slidable to bring in a direct-drive clutch.

Patent GB-1078632-A (GB)
Title: Improvements relating to the manufacture of draftable staple fibre band or sliver
IPC: D01H13/30
Filed: 1964-08-12
Abstract: In a draftable staple fibre band or sliver the individual fibres are in parallelism and surrounded by a fixing agent which binds the fibres to one another so that the breaking length of the sliver exceeds that of a twisted roving of the same fibres untreated by fixing agent.  The sliver is produced by forming e.g. by carding, doubling and drafting, a homogeneous, draftable staple fibre layer or strand; effecting an initial introduction of a dissolved fixing agent e.g. corn, rice or potato starch and/or polyvinyl alcohol, sodium alginate, casein or cellulose xanthogenate in aqueous solution; consolidating or condensing the layer into a sliver of small specific volume and withdrawing excess agent; depositing the sliver and bonding it by evaporation of the agent solvent; optionally, drying the sliver, forming a doubled fibre arrangement from a plurality of this sliver and subsequently rupturing the bond by passage through a drafting zone; subjecting the sliver leaving this zone to a further introduction of a dissolved fixing agent, which may be the same nature as, but in smaller concentration than, the initial agent, or a solvent to reactivate the previously introduced agent, consolidating the fibres and extracting excess liquid and depositing the final sliver.  Introduction of fixing agent at the first stage may be accompanied by colouring matter, bleaching agent, finishing additives such as antistatic agents, fungicides, bactericides.  Apparatus for the delivery under pressure and the application of the solution of, or solvent for, the fixing agent, Fig. 3 (not shown) comprises a reservoir (14) incorporating a heating coil (15) and to which excess agent &c. is returned, from application apparatus (6 and 23) coacting with squeeze rolls, via a pump and filter (not shown).  The reservoir has provision for separate introduction of different constituents.

Title: Improvements relating to colour photography
IPC: G03C7/18
Filed: 1936-12-01
Abstract: 486,043. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Dec. 1, 1936. No. 32916. [Class 98 (ii)] A previously determined faulty colour reproduction in photographic colour picture material is corrected by subjecting each component to a second exposure of adjustable period that is independent of the normal exposure. In an example in which an excessive sensitization of the green sensitive layer is compensated, the film comprising blue sensitive, green sensitive and red sensitive layers is exposed and subjected to reversal development. The first development is not accompanied by dyestuff formation. In the second development, the layer yielding the purple image is illuminated more strongly. It is necessary in this case that the sensitizer should not be destroyed during the first development. In a further example, the layers of the material are separated by yellow filter layers, and in the second exposure the two outer layers are illuminated with blue light. The yellow filter dyestuff in at least one of the layers is destroyed and the two exposed layers are developed to colour. The inner third layer is then exposed and developed to colour. In the variation of the second illumination a set of colour filters red-green-blue is used, and variation may be produced either in the duration of each illumination or by providing different apertures or grey filters in front of each colour filter. The film packs may be accompanied either by a table setting out appropriate numbers for the filters or openings to be used, or by perforated metal or cardboard sheets for use in front of the filters.

Abstract: 1325551 Ion beam apparatus INSTITUT FUR PLASMAPHYSIK GmbH 7 July 1970 [23 July 1969] 32987/70 Heading H1D An ion beam microprobe comprises an ion source 10, Fig. 1, and an ion lens 12 adapted to produce a parallel beam which passes through a 180 degree homogeneous magnetic field 14 to emerge as a parallel beam which is focused by a condenser lens 18 and an objective lens 22 on to the test object 24 to produce secondary ions which are analyzed by a mass spectrometer 26, and after 90 degree deflection the magnetic field 14 is adapted to produce a mass spectrum (shown by a dashed line) from which ions of a desired mass may be selected by a diaphragm 16 provided with a slit; the slit may be of variable width and/or the diaphragm 16 may be movable parallel to the spectrum. Preferably the apparatus also includes an electron beam generating system 30, a second 180 degree magnetic field 32 which has little effect on the ions but deflects electrons into the same path as the ions, and an X-ray spectrometer 34 for analysis of X-rays generated by electron bombardment of the specimen. Lenses.-The lens 18 and/or the lens 22 may comprise earthed magnetic polepieces 40, 42, Fig. 2, provided with central apertures and an apertured diaphragm 44. It is shown that the electrostatic lens so formed can simultaneously focus ions of 10KV energy and electrons of 4KV energy. For electrons of higher energy the magnetic field is energized to provide the required additional focusing power; the effect of the magnetic field on the ions is small and may be compensated by adjustment of the potential U L  of the diaphragm 44.

Title: Improvements in or relating to clay guns
Inventor: PAWSON GEORGE
IPC: C21B7/12
Filed: 1957-10-23
Abstract: 850,697. Clay guns. POWER-GAS CORPORATION Ltd. Oct. 3, 1958 [Oct. 23, 1957], No. 33018/57. Class 51 (2). A clay gun 1 is suspended by sliding bearings 8 and 9 engaging a slide bar 11 attached to an arm 10 pivoted about a post on a base 14 by a fluid cylinder 15 rotated about a stationary shaft 16 fixed to the post, the rear double-acting cylinder 7 being also attached to the arm 10. As the gun is swung into line with the tap hole, a catch 18 pivoted at 17 to the end of the slide bar 11 is latched on to a sneck 19 attached to the furnace by a lever 25. Fluid pressure applied to cylinder 7 is transmitted to ram 4 in cylinder 1 by piston rod 5 which is surrounded by an asbestos or like bellows 27. Initial pressure on the ram 4 is transmitted through the clay causing forward movement of the gun into the furnace taphole, further pressure discharging the clay into said taphole. Reversal of pressure in the cylinder 7 causes the ram 4 to retract until it strikes stop 12 whereupon it withdraws cylinder 1 to a retracted position in which holes in sliding bearing 9 and slide bar 11 coincide and receive a locking pin 26. The gun is then swung away from the furnace about the shaft 16 to a re-charging position. Control system.-The movements of the gun are controlled by a combined hydraulic and electrical system shown diagrammatically in Fig. 5. Liquid from a tank 30 is supplied by electrically driven pump 29 respectively through reversible valves 37 and 42 operated by switches 58 and 59 and solenoids 46 and 47 to the rotary cylinder 15 and the operating cylinder 7. Cams 48 and 49 actuated from cylinder 15 ensure that during the ten degrees of rotation in either direction a throttle valve 39 considerably decreases the rate of turning of said cylinder. A throttle valve 44 also operates through a device 55 when the gun nozzle approaches the taphole, by uncovering a part 51 in the cylinder 7 and admitting liquid to said device 55. Modification.-In a modification, Figs. 6-8 (not shown), the twin cylinder gun is mounted on a carriage sliding over taper roller bearings in raceways on a bar attached to the pivoted arm, said carriage being reciprocated by a fluidoperated cylinder. Movements of the fluidoperated rotation cylinder, the carriage-operating cylinder and the clay discharge cylinder are controlled by a pressurised liquid system, Fig. 9 (not shown), producing operating movements similar to those of the first embodiment. The appropriate reversible valves are controlled by electrically operated microvalves.
