Title: Improvements relating to the printing of kinematograph films
IPC: G03B27/08
Filed: 1929-05-25
Abstract: 331,060. Bizot, M. G. M. G. March 11, 1929, [Convention date]. Printing-apparatus.-A machine for printing a sensitive film requiring a long printing-exposure, of the kind in which the film is wound, together with the negative film and an opaque covering band in a helical path on the outside of a glass drum along the axis of which is disposed a source of light, screening discs are provided within the drum and are continuously moved in order to intercept rays other than those which axe normal to the wall of the drum without producing shadow effects on the printed film. The drum is surrounded by a rotatable frame carrying reels for winding and unwinding the films and the opaque band on and off the drum. As shown, the apparatus comprises a frame 1, Fig. 1, supporting ,a. glass drum 2 enclosing an axially-disposed mercury vapour lamp 3. Rods 5, suspended from a wheel 6 carrying rollers 7 resting on a circular cam 8, carry transversely-disposed discs 4 which intercept rays directed non-radially. During exposure, the wheel 6 is rotated slowly through gearing 10, 11, 12 from a motor 9, and rises and falls as the rollers 7 ride on the cam 8; the consequential movements of the disc system prevent the detrimental effect upon the print of the shadows of the discs 4 and rods 5. Surrounding the drum, is a frame driven by a worm-wheel 13, Fig. 2. Screwed rods 15, 16 thereon carry pinions 151 , 15<11>, 16<1>, 16<11> engaging stationary wheels 1<1> 1<11>. Nuts 17, 18 mounted on the rods support an inclined carriage 19 on which are mounted reels 20, 21, 22 which carry respectively the negative film, the positive film material, and the opaque band. The reels are connected through free-wheel mechanism to pinions geared to a wheel driven through a spherical joint by a shaft 26 carrying pinions 26<1>, 26<11> meshing with the stationary wheels 1<1>, 1<11>. As the wheel 13 is driven, the frame rotates, the carriage 19 moves slowly along the drum, the reels 20, 21, 22 freewheel on their shafts, and the films and the opaque band are unwound in a helical path upon the drum. On reversing the rotation of the wheel 13, the reels 20, 21, 22 are locked to their driving pinions, and the films and band are rewound on the reels. Additional set of reels 23, 24, 25 may be mounted on the platform and be similarly geared to the pinions so that, while one pair of films is being wound off the drum, a fresh pair may be simultaneously wound on. The Specification as open to inspection under Sect. 91 (3) (a) states also that the sensitive film may be unperforated before printing, the perforations being made subsequently in a machine adjusted continuously to punch them at the places where images of the perforations of the negative film are impressed. This subject-matter does not appear in the Specification as accepted.

Abstract: 605,951. Securing furniture to floors. WARREN McARTHUR CORPORATION. June 26, 1945, No. 16257. Convention date, Sept. 15, 1944. [Class 52(ii)] [Also in Group XXV] A locking device for removably fastening a chair &c. to a floor or wall, of the kind in which a locking element of non- circular cross-section is inserted in a housing through a similar shaped opening and then rotated to prevent withdrawal, has a closure for the opening and means for normally and yieldingly maintaining the closure in said opening. The device consists of two units 13, 25, the unit 13 being fastened to the floor by screws and comprising a hollow base 14 with a radial flange 15 and a removable lock plate 17. A hexagonal closure 21 is held by a spring 23 in a hexagonal opening 20 in the lock plate, bars 22 on the closure riding in vertical grooves 16. The unit 25 comprises a housing 26 over which a chair leg is riveted and which has a recess into which is inserted a member 40. This member is rotatably mounted on a sleeve 37 having a flange 38 fitting tightly in a recess 31 in the housing and has an arm 42 projecting through a groove in the housing and a hexagonal locking element 44. It also has a spring compartment 45 in which is a spiral spring 50 attached at one end to the member 40 and at its other end to the sleeve 37. The member and its associated parts are secured to the housing by a bolt 52 passing through the sleeve 37 into a compartment 25 in the housing and a washer and nut 55. The arrangement of the spring 50 is such that the locking element 44 is not normally in registering alignment with the opening 20. The lever 42 may be rotated to the limit allowed by the groove in the housing 26 through which it projects (30 degrees), thus rotating the member 40 against the spring 50 and bringing the element 44 into alignment with the opening 20. The element may then be moved through the opening, pressing down the closure. Upon releasing the lever, the locking element will rotate so that it can not be withdrawn until the lever is again actuated. Other non- circular shapes for the opening 20, closure 21 and locking element 44 are shown.

Title: Improvements in or relating to hydraulic pit props
IPC: F16K17/10
Filed: 1957-05-23
Abstract: 868,073. Fluid-actuated valves. BECORITGRUBENAUSBAU G.m.b.H. May 23, 1957 [June 25, 1956], No. 16361/57. Class 135. [Also in Group X] A pressure-relief valve in an hydraulic pit prop including telescopic outer and inner tubes 1, 2, Fig. 1, constituting a pressure chamber 3 and reservoir 5 respectively and an interconnecting tube 6 over which a piston 4 connected to the inner tube slides, comprises a valve member 15, Fig. 3, continuously urged towards closure by the pressure in the chamber 3 and displaceable out of and into closed position by a valve-operating member comprising a leaky piston 22 and a rod 21 and an hydraulic intensifier. The hydraulic intensifier comprises a liquidfilled branch 26 connected to a space 24 between the rod 21 and a piston 25 of much larger area than the rod 21 having an extension 28 engaging the valve member 15. The leaky piston 22 is subjected on both sides to the pressure in the chamber 3 and loaded by a spring 23. On the pressure in the chamber 3 rising to a valve whereby the differential pressure acting on the opposite sides of the piston 22 overcomes the spring 23 the piston and rod 21 move rightwardly. The force overcoming the spring by virtue of the difference in areas of the rod 21 and piston 25 is increased and acts on the piston 25 and the valve member 15. The valve member 15 will, however, remain seated, since it is larger in diameter than the rod 21, until the pressure in the chamber 3 has risen to a still higher value at which the chamber pressure acting on the valve member 15 is overcome by the resulting increased pressure acting on the piston 25. The valve member 15 then opens to relieve pressure from the chamber 3 to the reservoir 5 through passages 13, 13a and 14, extension 28 of the piston 25 and the tube 6. The branch 26 is closed by an adjustable plug 27 to vary the volume of the intensifier, hence the loading on the spring 23 and consequently the operating pressure of the valve.

Filed: 1930-02-17
Abstract: 336,811. Elkington, H. D., (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Feb. 17, 1930. Butanol and higher alcohols are obtained by subjecting ethanol vapour under pressure and in the presence of a catalytic mass comprising magnesium oxide together with a smaller quantity of copper oxide, to temperatures sufficient to maintain all the ethanol in the state of vapour, but not exceeding 400‹ C. and preferably not greatly exceeding 325' C. The pressures employed are preferably high, for example, 130-300 atmospheres. The catalysts preferably contain about 20 or 40 per cent of copper oxide and the remainder of magnesium oxide. Unconverted ethanol may be separated from the reaction products and used again, and in this way the process may be made continuous. An example is given. Specifications 282,448, 287,846, and 326,812 are referred to.
Patent GB-982098-A (GB)
Title: Improvements in production of alumina
IPC: B01J41/20
Filed: 1962-04-30
Abstract: Substantially iron-free alumina is obtained from clay containing iron and aluminium by leaching the calcined clay with hydrochloric acid, converting iron in the leach liquor to a complex anionic ferric chloride [FeCl4-], contacting the liquor with a basic anion exchange polymer, thus separating iron from aluminium, and recovering alumina from aluminium chloride remaining in the liquor.  In an example, clay is calcined at 1200 DEG  F. for 1 1/2 hours, ground and leached by stirring with 20% w./w. aqueous HCl at a temperature of at least 160 DEG  F. for one hour.  Silica is separated and the solution containing chlorides of iron and aluminium is oxidized to an E.M.F. of 600 mV. at room temperature either electrically or using a suitable oxidizing agent.  The solution is then contacted with a basic anion exchange polymer, which may be solid, e.g. a granular quaternary ammonium resin, or which may be liquid, e.g. a 0.1 molar solution of a secondary amine in kerosene containing an emulsion-preventing agent, e.g. n-decyl alcohol.  In the latter case, mixer-settler extraction equipment may be used to effect contact. The iron-free aluminium chloride solution is evaporated and the residue is roasted in a kiln to give alumina, containing less than 0.05% Fe2O3 and less than 0.04% SiO2. Condensate from the evaporation stage and the roaster gases may be processed to obtain hydrochloric acid for re-use.  Adsorbed complex ferric chloride anions may be eluted from the polymers with water or 0.5% w./w. aqueous HCl after entrained leach liquor has been displaced with 20% w./w. aqueous HCl. The eluate may be evaporated to give a concentrated ferric chloride solution or further processed for conversion of chloride to hydrochloric acid for re-use and for production of pure ferric oxide.

Abstract: 369,477. Feeding devices for roller &c. mills. BUHLER GEB, Uzwil, Switzerland. June 5, 1931, No. 16518. Convention date, Sept. 13, 1930. [Class 59.] A device for feeding cacoa, soapy material &c. to a roller mill &c. comprises a tray 3 adapted to be reciprocated in a direction parallel to the nip of the rolls 4. The tray may be free to swing or is mounted on a shaft 7 reciprocated by a member 26, Fig. 5, mounted on a cam-ring 27 fixed to a rotary shaft 25 or by an unbalanced revolving mass 29, Fig. 6, mounted on a bell-crank lever 30. The free end of the tray 3, Fig. 2, is suspended by a chain from one arm 10 of a bell-crank lever the other arm 13 of which is supported by a spring 14 from a feed. shoot 2. The amount of feed passing on to the tray is regulated by a sliding door 12 and an excess of feed in the shoot 2 depresses the tray against the pressure of the spring 14 until the excess has been discharged into the mill whereupon the spring returns the tray to its normal position. The arm 13 and spring 14 may be dispensed with, the amount of feed being regulated by a hand movement of the bell crank 10. A slidable weight attached tc the arm 13 may replace the spring 14. In Fig 4, the side 17 of the shoot is hinged at 18 and is balanced against internal pressure of the material in the shoot by a movable weight 23 and a link 24 may be used to connect the side 17 and tray. Increase of pressure of material forces the side 17 outwardly and consequently depresses the tray to increase the feed opening 11 between the tray and side 17. When the excess has been discharged to the mill the feed opening is restored to its original dimensions.

Filed: 1948-06-23
Abstract: 653,927. Stereoscopic apparatus. DUDLEY, L. P. C. J., COOPER, W. R. D., and BROWN & CO., Ltd., F. E. June 23, 1948, No. 16877. [Class 97 (i)] [Also in Group XVIII] In apparatus for use in displaying a parallax panoramagram or stereogram, the usual line grid or lenticular screen employed for viewing such pictures has light reflective material applied thereto so as to form a semi-transparent mirror which when subjected only or mainly to front illumination serves to obscure the picture and to present a light reflecting surface and when subjected only or mainly to rear illumination permits the picture to be seen. The apparatus shown comprises a casing 6 having compartments 7, 8 and 9, each of which contains an electric lamp 15, 16 or 17 connected through a junction box 21 with a current source and a floor switch 24. In front of lamp 16 is mounted a diffusing screen 10, a parallax panoramagram or stereogram 11, and a line grid 12, the lines of which are formed of reflecting material, e.g. silver so that the grid also acts as a semi-transparent mirror. Thus, if a person stands on a floor board 22, the picture 11 can be seen, but, when the person moves from said board, the picture is obscured from view. Panels 14 carrying advertising material may be positioned in front of the lamps 15, 17 in the compartments 7, 9 and in front thereof transparent sheets or semitransparent mirrors 14 may be mounted. The line grid may have light-reflecting lines independent of the usual grid lines and preferably the latter are disposed at an angle to the light-reflecting lines. The lenticular screens which may be used to observe the stereoscopic picture have applied to the lenticular face of each thereof linear zones of light reflective material, which zones extend longitudinally of the screen. In the Provisional Specification, it is stated that a semi-transparent mirror may be provided independently of the line grid or lenticular screen and that the stereoscopic pictures may be of the kind which require polarizing or colour filters for viewing purposes.
