Title: Process for the generation of synthesis gas with the simultaneous recovery of aromatic hydrocarbons
IPC: C10J3/00
Filed: 1939-07-17
Abstract: 531,288. Gas manufacture. DIDIER-WERKE AKT.-GES. July 17, 1939, No. 20704. Convention date, Aug. 27, 1938. [Class 55 (i)] In a process for the generation of synthesis gas for the production of motor fuel and other synthetic products, solid fuels for example lignite, brown coal, or peat are carbonized in continuously operated retorts, being charged into a preheating chamber 8, the distillates from an upper zone a flowing downwards to a roof-shaped offtake 11 from the underside of which they pass to an outlet 13. The temperature of the lower part of zone a is 500‹C. to 600‹C., and that of the highest temperature zone b is from 800‹C. to 1000‹C., an offtake 14 from this zone leading to an outlet 16 into which water gas from the lowest zone c also passes. The low temperature distillates from outlet 13, after removal of light oils and benzol, are mixed with the carbon-monoxide and hydrogen from outlet 16. These mixed gases are converted into liquid fuels to which anti-knock properties are given by admixture with a portion of the aromatic hydrocarbons recovered from the low temperature distillates.

Title: Improvements relating to chocolate or other edible confections
IPC: A23G1/20
Filed: 1936-07-28
Abstract: 480,951. Confectionery ; cocoa preparations. PHILLIPS, S. B., and WHITTAKER, A. July 28, 1936, No. 20854. [Classes 28 (i) and 129] In the manufacture of chocolate or other confections of the kind which are solid at ordinary temperatures and which contain fat, which on melting at higher temperatures gives to the confection a plastic or fluid form, a cellular, honeycomb or like open structure is produced by dissolving carbon dioxide gas in the mass, under pressure, and subsequently lowering the pressure, before solidification by cooling, whereby some of the dissolved gas is liberated. The chocolate, after the usual graining or conditioning, is placed in a closed vessel a kept at a temperature of about 90‹ F. by a jacket b and is agitated by a stirrer c. The carbon-dioxide is introduced under pressure, e.g., 30-50 lb. per square inch, through a perforated conical cap d, the space e being supplied with gas by a pump g. The upper end of the chamber a is connected by a pipe i to the pump suction which is connected also to a gas supply reservoir k. The chocolate is discharged through a valve m and nozzle l, and is received in moulds or on a plate. The action of the escaping gas may be facilitated by tapping or agitating the moulds or plate, and the appearance of the final product may be controlled by the regulation of this agitation. Alternatively, the mass may be discharged into moulds or on to a plate contained in a pressure chamber in which it is agitated, the pressure being then reduced. The mass may be discharged into chocolate lined moulds, or it may be coated after solidification and subdivision. Nuts, raisins &c. may be placed in the moulds before admission of the mass, or may be added before solidification. According to the Provisional Specification, the confection may be made into a beverage, and a gas other than carbon-dioxide may be used. Reference has been directed by the Comptroller to Specifications 459,582 and 459,583.

Title: Image projection apparatus
IPC: G03B21/11
Filed: 1971-04-19
Abstract: 1351291 Optical projection apparatus; cassette EASTMAN KODAK CO 19 April 1971 [3 Feb 1970] 21004/71 Headings G2E and G2J A projection apparatus including a housing having a back projection screen on one wall thereof and being suitable for cassettes 84 of microfilm strip includes a cassette loading device movable between a loading/unloading position and a projection position. The loading device includes a plate 36 having two supports 49 for the ends of the cassette 84 slideably fitted by slots 52 and pins 50 (only one visible in) Fig. 3 to it. The device is shown in the loading / unloading position in which the cassette 84 of stripfilm is placed on the supports 49 and the device slid downwards guided by strips 46 attached to part 44 of the apparatus casing. As the device is lowered supports 49 which are connected to plate 38 move upwards relative to the plate 36 because the plate 38 engages projections 54. This relative movement causes spindles 56 to engage the spools 102, 103 in the cassette 84 and engagement is complete when surfaces 14, 59 are flush and the device is in the projection position. In this position two transparent members 118, 120 enter the cassette base through an aperture (122), Fig.4 (not shown) and sandwich and thereby align the film at the projection gate 96, 98 in the cassette. The film-strip is advanced by rotating knob 19 in the desired direction so rotating wheel 60, which, by virtue of the friction surfaces 61 of the wheels, causes assembly 68 to follow it until the appropriate idler wheel 64, 65 is in contact with both the wheel 60 and the wheel 62, 63 respectively. Rotation of the knob 19 thus advances the film by rotation of the take up spool of the cassette 84. The film can be moved in either direction at will and loaded/unloaded with the film distributed in any manner between the spools 103, 104. Focusing is by means of an eccentric projection 66 on shaft 76 attached to knob 20 which engages a slot 82 in the housing of projection lens 28.

Abstract: 478,893. Fluid-pressure reciprocating engines. BUGATTI, J. July 31, 1936, No. 21267. Convention date, Sept. 16, 1935. [Classes 122 (i), 122 (ii), and 122 (iii)] A fluid-pressure engine is provided with coaxial sleeve valves provided with admission and exhaust ports around their peripheries, which valves are surrounded by a valve which may be adjusted by hand or the governor to control the admission. The valves are arranged in the end of the cylinder around the cylinder head and the end of the piston. The opening and closing of the ports are controlled by different valves. The cylinder head 1 is closed by a head 4 through which pass the valve-actuating rods 5. The cylinder head is provided with a safety valve 6. Admission and exhaust chambers 7, 8 are arranged around the heads. These function as heating-jackets and may serve a number of cylinders. The piston is stepped to accommodate the valves and has two series of packing-rings. The cylinder has drainage orifices 22 in its sides. The valves are operated by crank or eccentric shafts 11 rotating in the same direction and driven by the main shaft at the same speed. The shafts 11 drive through cranks 12, 14 the sleeves 13, 15 respectively. Telescopic casings 17 connect the casings of the crank-shafts 11 with the cylinder head 4 to facilitate lubrication. The supply is controlled by sleeve 18. The lower edges of the inlet ports in sleeves 13, 15 register at full admission. Admission lead is constant and is determined by the lower edge of the port in valve 15 passing the head 4. The cut-off is effected by the up movement of the lower edge of the port corresponding in sleeve 13 past the sleeve 18. Reversal is effected by an angular displacement of the crank or eccentric shafts by means of helical gearing. The cylinders may be arranged for compound working with one high-pressure and two low-pressure cylinders. With multiple-cylinder engines and cranks at 90‹, admission may extend beyond 90‹. Exhaust is controlled by a second series of ports below the admission ports.

Title: Improvements in or relating to the treatment of liquids with activated carbon
IPC: B01D15/00
Filed: 1951-09-10
Abstract: In a process of treating liquids with activated carbon for purification decolorization, deodorization, &c., at least two different types of activated carbon are successively used, the type first used having a relatively steep absorption isotherm whilst the type or types subsequently used has or have a flatter isotherm or progressively flatter isotherms.  The carbons may be used in granular form, for example as filters in layers, the first filter adsorbing impurities of higher molecular weight or present at greater concentrations in the liquid, and the second filter adsorbing impurities of lower molecular weight or as lower concentrations.  The carbons may also be used in powdered form either deposited on filtering material through which the liquid to be treated is passed, or mixed with the liquid.  In the latter case the liquid may be filtered after having been in contact with a carbon of the first type for sufficient time, and before being mixed with carbon of the second type, or the different types of carbon may be added to the liquid without intermediate filtration, sufficient time being allowed for a carbon of one type to react fully with the liquid before carbon of another type is added.  The liquid may be treated partly with granular activated carbon and partly with powdered activated carbon. The carbons may be added to the liquid wholly or partly in counter-current.ALSO:In a process of treating liquids with activated carbon at least two different types of activated carbon are used in succession the type first used having a relatively steep adsorption isotherm whilst the type or types subsequently used has or have a flatter isotherm or progressively flatter isotherms.
