Title: Improvements in the manufacture of ferric oxide
IPC: C01G49/06
Filed: 1925-04-01
Abstract: Ferric oxide and sulphur trioxide are obtained from ferrous sulphate by heating the hydrated crystals by the action of flaming gases so as to liberate the water of crystallization at a temperature high enough to prevent caking (i.e., above 64 DEG  C.), grinding the product (monohydrated sulphate) in a mill, oxidizing it to a basic ferric sulphate by hot air in an oxidizing chamber, and then calcining in a roasting furnace.  The first heating may be effected in a rotary tube with a helical, drag, or rake conveyer or other agitating and conveying device and with internal gas burners, the flames from which directly heat the crystals.  The vapour produced in this apparatus is withdrawn for instance by an exhaust fan.  The Specification as open to inspection under Sect. 91 (3) (a) states that the first treatment of the crystals is effected by direct heat.  This subject-matter does not appear in the Specification as accepted.ALSO:Ferric oxide and sulphur trioxide are obtained from ferrous sulphate by heating the hydrated crystals by direct heat by the action of flaming gases so as to liberate the water of crystallization at a temperature high enough to prevent caking (i.e. above 64 DEG  C.), grinding the product (monohydrated sulphate) in a mill, oxidizing it to a basic ferric sulphate by hot air in an oxidizing chamber, and then calcining in a roasting furnace.

Title: Improvements in or relating to vulcanizing presses
IPC: B29C35/00
Filed: 1940-05-17
Abstract: 543,489. Vulcanizing presses. McNEIL MACHINE & ENGINEERING CO. May 17, 1940, No. 8810. Convention date, June 23, 1939. [Classes 70 and 87 (ii)] A safety device, directly responsive to the movement of the upper mould section 5, restricts the extent of the opening movement while the air bag B is inflated above a pre-determined degree. The invention is described in connection with the moulding press described in Specification 526,659. A bar 30 is fixed at 31 to one of the links 16 and is slotted at 32 to receive a guiding pin 33 on the link. An adjustable screw 35 on the lower end of the bar is engaged by a blade 36 mounted in a lever 37 pivoted at 37a on the link. A spring 38 urges the lever 37 upwardly. If, when the mould section 5 begins to rise, there is much pressure in the air bag B (as in Fig. 3), the link 16 will be stressed, this stress resulting in (a) stretching of the link 16 so that the nut 35 on the end of the (unstressed) bar 30 will move upwardly relatively to the pivot 37a and allow the lever 37 to pivot clockwise, and (b) the slight play at the pivot 18 being taken up so that the link 16 moves bodily upwards. The result of (a) and (b) is that a roller 41 positioned on the free end of the lever 37 is moved upwards so that an electric circuit breaker 15 lies in its path and is engaged, so stopping opening of the press. The position of the roller may be adjusted by means of elements 40, 42, 44. A pivoted shield 48 is provided to prevent the roller 41 accidentally striking the circuit breaker 15 when the press is being closed. Reference has been directed by the Comptroller to Specifications 313,102 and 316,896, [both in Class 87 (ii)].

Title: A new projection screen
IPC: G03B21/56
Filed: 1936-03-25
Abstract: 477,384. Projection screens. MARTINEZ, A., MARTINEZ, M., and MARTINEZ, A. March 25, 1936, Nos. 8917 and 8918. Convention dates, March 25, 1935 and Feb. 29, 1936. [Class 97 (i)] A screen moved continuously or reciprocated in the plane of the projected image comprises specular surfaces arranged in rows which are transverse to the direction of motion, the surfaces having relatively small radii of curvature in the direction of motion and relatively large radii of curvature in a direction transverse thereto ; all the surfaces in one row are parallel to the projection plane or are inclined thereto at the same angle, and the surfaces in any one row are displaced relatively to the surfaces in adjacent rows or have an inclination different from the inclinations of those in adjacent rows. The curvatures may be derived from a circle, parabola, cycloid, hyperbola, or ellipse, or from combinations thereof. The projected images may be stereoscopic pairs, or may be projected from solid objects. Fig. 6 shows part of the surface of a screen in which the specular surfaces 1a ... 1l are arranged in horizontal rows, the surfaces in each row being laterally displaced relatively to those in the rows above and below them, to form cycles in which the rows 1a and 1l correspond. Each surface distorts a light point into a line f ... i, and the vertical movement of the screen causes the lines to produce light areas F ... I which are contiguous and cover the image field. Fig. 4 shows diagrammatically the positions of the surfaces in four consecutive rows of an alternative construction, in which the surfaces a ... d in the rows are not laterally displaced but are arranged at different inclinations to the projection plane. The surfaces may be formed in rows from sheet-metal, as shown at c, Fig. 5, or may be cast, pressed, &c. in cycles ; the vertices of the surfaces in each row may lie on a circular arc. The surfaces may be carried by chains running over rollers 5, Fig. 10, and the rows may be contiguous or spaced to permit the spectators to see objects &c. behind them or scenery &c. painted on a canvas 17. The canvas 17 may be wound on rollers 18, so that the scenery may be varied, and a multicoloured web 19 wound on rollers 20 and illuminated by lamps 21 may be provided behind the canvas ; the canvas may be omitted, .when the web and lamps are provided. A construction is described in which the screen is rotated in the projection plane, the rows of surfaces being radial. Fig. 12 shows a construction for rear projection, in which the specular surfaces 1 are backed by plane specular surfaces 24 inclined at 45‹, the projected image being viewed in the surfaces 24. Shutters 26 cut off direct vision of the projector lens.

Title: Process for the preparation of malic dialdehyde
Filed: 1953-04-01
Abstract: The invention comprises aqueous dilute acid solutions containing malic dialdehyde.  Malic dialdehyde is prepared by hydrolysing a 2 : 5-dialkoxy- or 2 : 5-diacyloxy-3-hydroxy-tetrahydrofurane in dilute aqueous acid solution.  2 : 5-Dialkoxy-or 2 : 5-diacyloxy-3-hydroxytetrahydrofuranes may be obtained by hydrogenating 2 : 5-dialkoxy- or 2 : 5-diacyloxy-3-hydroxy - 4 - halogen - tetrahydrofurane in an alcoholic medium and in the presence of a binding agent for hydrogen halides.  2 : 5-Dialkoxy- or 2 : 5-dialkoxy-3-hydroxy-4-halogen-tetrahydrofuranes may be prepared from 2 : 5-dialkoxy- or 2 : 5-diacyloxy-dihydrofuranes by the addition of hypochlorous or hypobromous acid or by treatment with reagents capable of effecting the addition of hypochlorous acid, e.g. tertiary butyl hypochlorite.  In an example, 2 : 5-diethoxy-3-hydroxy-tetrahydrofurane is treated with O.IN hydrochloric acid to obtain malic dialdehyde.  The bis-p-nitrophenylhydrazone is prepared.  2 : 5 - Diethoxy - 3 - hydroxy - tetrahydrofurane is obtained by hydrogenating 2 : 5-diethoxy - 3 - hydroxy - 4 - brom - tetrahydrofurane in methanol solution in the presence of Raney nickel and potash.  The solution is treated with carbon dioxide, filtered, evaporated and extracted with ether.  The ether is evaporated from the extract and the residue is fractionated under reduced pressure.
Patent GB-590392-A (GB)
Title: Improvements in or relating to the manufacture of magnets
IPC: C09D5/23
Filed: 1945-04-11
Abstract: Permanent magnets are made from a powder composed of grains of a magnetic material having dimensions of the order of those of colloidal particles e.g. 1/100 to 1 micron by agglomeration with or without a binding agent at a temperature low enough to avoid sintering or coalescence.  The powder may be obtained by decomposing in a slightly inclined, externally heated, rotating tube, a compound or a mixture or a solid solution of compounds such as formates, oxalates, hydroxides or carbonates of one or more magnetic metals e.g. iron, nickel, cobalt, at about 300 DEG C. accompanied or followed by reduction preferably under hydrogen or carbon monoxide. The reducing gas may travel up the tube while the powder passes down. Alternatively the Raney method may be used in which the metal powder is produced from an alloy of aluminium with iron or nickel by attacking with soda to remove the aluminium.  In another method hydrogen is bubbled through iron carbonyl at 50 DEG C. and the mixture of carbonyl iron vapour and hydrogen so obtained is bubbled through oil at 300 DEG C.  A suitable powder may also be obtained as the condensate, reduced if necessary, of a volatilized metal.  The powders may be pyrophoric and are then embedded in acetone or kept in a reducing atmosphere. The magnetic metals may be alloys containing chromium, manganese, aluminium, bismuth, titanium, molybdenum, tungsten or copper. Examples are given of the proportions and temperatures to be used, and the densities, high coercive force and remanence of the permanent magnets made by compressing the powders so obtained.

Title: Improvements in or relating to mechanism-selecting circuits
IPC: H04Q3/00
Filed: 1940-05-24
Abstract: 542,081. Automatic exchange systems. ELECTRICAL RESEARCH PRODUCTS, Inc. May 24, 1940, No. 9179. Convention date, July 11, 1939. [Class 40 (iv)] An allotting circuit such as the starting circuit of a call finder comprises a number of threeelectrode neon &c. tubes 152, 154 &c., one for each finder &c., each associated as shown with a pair of resistances 113, 115 in a chain circuit and with a condenser 151. When, as the result of a demand for a finder &c., a break-down potential is applied by a sub-group starting relay such as 100, 156 to the left-hand end of a section of the chain, the potential builds up to the right from this point until it reaches the tube of an idle finder. This tube breaks down to start its finder and so lowers the potential that no other tube responds. When the callfinder switches through, it disconnects the cathode of its tube and releases the starting relay. In the arrangement shown, each section of the chain corresponds to a level in a group of double-wiper finders. Assuming tube 152 to breakdown, its relay 102 causes the finder vertical magnet 109 to interact with relay 167 until the vertical wiper 112 finds the terminal marked by the starting relay, whereupon 176 pulls up in series with 167 which thus remains operated. Relay 168, which has remained operated during vertical stepping, now falls and energizes the rotary magnet. Vertical wiper 112 moves off the bank 170 at the first step. If neither of the lines in the first position is calling, wiper-changing relay 169, which operated and locked at the end of the vertical movement, is held over wiper 122. 167 which was released by the rotary magnet therefore pulls up again over wiper 130 and the rotary magnet is re-operated. This interaction continues until the calling position is reached whereupon 169 falls if the calling line is reached over the lower set of wipers. In any case no circuit is made for 167 and switching relay 153 being no longer short-circuited pulls up in series with 167 and holds 169 if the calling line is reached over the upper set of wipers. 153 also disconnects the cathode of the discharge tube to release 102 and energizes the cut-off relay.

Title: Colour developing compositions
Inventor: EDENS CHARLES OLIN
IPC: G03C7/413
Filed: 1970-02-26
Abstract: 1278744 Photographic colour developer composition EASTMAN KODAK CO 26 Feb 1970 [27 Feb 1969] 9250/70 Heading G2C A colour photographic developer composition comprises a primary aromatic amine colour developing agent and an antioxidant having the formula R<SP>1</SP>-CH(OH)-CO-R in which R is H, carboxyl, alkyl having 1 or 2 C atoms, or hydroxy alkyl having 1 or 2 C atoms and R<SP>1</SP> is H, carboxyl, hydroxymethyl or formyl, such that when R is carboxyl, R<SP>1</SP> is not a hydroxymethyl group and such that the compound is capable of existing in equilibrium as an enol form and is not capable of intramolecular cyclization. Concentration of the above compound is in the range 0À1-20 g/l and of the developing agent, 0À5-14 g/l. Typical of the above compounds are dihydroxyacetone, glycolaldehyde, glyceraldehyde, and dihydroxymaleic acid. The composition may contain water, an alkali e.g. an alkali metal tetraborate, an alkali metal sulphite, a diffusible dye forming coupler, a silver halide solvent, an antifoggant, a diffusible competing coupler or a thickening agent e.g. a carboxy (lower alkyl) substituted cellulose. Numerous colour developing agents are listed. These colour developing compositions give better photographic speeds and densities than those containing either no antioxidants or known antioxidants. These antioxidants are not silver halide solvents and prevent loss of colour developing agent due to aerial oxidation and also of coupler which would otherwise couple with the aerially oxidized colour developing agent.
