Title: Improvements in and relating to photographic printing employing image masks
IPC: G03C5/02
Filed: 1944-12-21
Abstract: 579,239. Photographic printing processes ; colour photography. KUDAK, Ltd. (Eastman Kodak Co., and Yule, J. A. C.). Dec. 21, 1942, No. 18089. Drawings to Specification. [Class 98 (ii)] A photographic black and white or colour record is reproduced with enhanced definition by printing from it while it is in register with a mask of complementary density to it (i.e. a positive when the record is a negative and vice versa), the mask being either (1) in printing relation with the record (i.e. in contact or projected focus therewith) and so diffuse that the diameter of the circle of confusion lies between V /15000M and V/1200M, where M is the magnification of the print relative to the record, and V is the distance at which it is to be viewed ; or (2) sharp, and so far out of printing relation that the diameter of the circle of confusion lies between the above-stated values; or (3) diffuse, and also so far but of printing relation that the diameter of the circle of confusion lies between V/15000M and V/600M. The meaning assigned to the expression " circle of confusion " in the three cases is defined in the Specification. The method is applicable for use in colour or contrast correcting of coloured records by the known masking method, in which case the mask is processed to lower gamma than the record ; it may also be used in the reproduction of black and white records. It is stated that the method results in increased tolerance in registration between the mask and the record, besides yielding improved definition. The Specification discusses the value of V for particular cases, and the corresponding values of the above formulµ. When the contrast of the mask is low, the range of permissible values of the diameter of the circle of confusion is taken as V/30,000FM to V/2400FM, where F is the ratio of the gamma of the mask to that of the record. Various ways and forms of apparatus are described for printing the ,mask by contact or projection from the record or a related record, either transparent or opaque, and for making the final print by contact or projection from -the combination of record and mask. Specifications 397,089, 506,581,512,608 517,265, 546,667, 553,196, 553,229 and 553,230 .are referred to.

Title: Improvements in the de-asphaltising of hydrocarbon oils
IPC: C10G21/00
Filed: 1950-07-20
Abstract: Hydrocarbon oils are deasphalted by mixing the oils with aromatic compounds having a molecular weight between 300 and 1500 and deasphalting the mixture under such conditions that at least a proportion of the added compounds is precipitated with the asphaltic bitumen.  The oils treated are residual oils which contain few high molecular weight aromatic compounds.  Aromatic compounds may be added to the oil in various ways, for example by adding a hydrocarbon oil containing aromatic compounds; by adding an aromatic extract, prepared by extraction with furfural, chlorex, phenol, antimony trichloride or other selective solvent, either of a different hydrocarbon oil or the oil which is to be deasphalted; or by adding asphaltic bitumen containing high molecular weight aromatic compounds.

Title: Improvements relating to internal combustion engines
IPC: F02D19/10
Filed: 1939-06-22
Abstract: 530,358. Gas and oil engines. CROSSLEY BROS., Ltd., and CARTER, H. D. June 22, 1939, No. 18187. [Class 7 (ii)] In engines which work on the compression ignition cycle as oil engines or use a gas or a gas and air mixture which is ignited by oil injection at or about the point of maximum compression, theoilsupplypump has a constant stroke and a spill valve which is under governor control during working by direct injection but unaffected by the governor and arranged for maximum spillage and small injections when using gas as fuel, the gas supply being under governor control. In the construction shown, a plunger b is actuated by a cam c and a spill or byepass valve e is operated from an arm d through a rod g the arm d resting upon an adjustable cam o. Carried by the arm is a rod h which rests upon a governor-controlled eccentric cam i when the cam o is adjusted so that the governor control is operative. A governor j acts through a link k to control the cam i and a gas throttle valve g. When running on gas fuel the spill valve is in its uppermost position so that a minimum amount of ignition fuel is supplied by the pump. By closing the gas valve rand by adjusting the cam o to permit the rod h to engage the cam i the pump is under governor control for working by direct injection of liquid fuel. By a suitable adjustment of the gas valve r and the cam o the engine may work with gas supplemented by oil as fuel.

Abstract: 356,813. Sound records. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Arnold, H. D. ; 174, Summit Avenue, Summit, New Jersey, U.S.A.) June 13, 1930, No. 18224. Convention date, June 14, 1929. [Class 40 (ii).] Two or more loud-speakers are controlled by a corresponding number of microphones over a single channel, each loud-speaker being rendered operative only in response to operation of the corresponding microphone. The channel may include a gramophone link, i.e. the speech and controlling currents may be recorded and subsequently reproduced at a different place. As shown, speech &c. from a microphone 1 after rectification operates a relay 10 to cause the transmission to line of current of a characteristic frequency e.g. 3500 which is selected by a circuit 26 and rectified, and energizes relay 22 to remove a short-circuit from the loud-speaker 19. A delay network 7 ensures that the speech &c. shall not arrive at the distant station until the loudspeaker is ready for it. Microphone 2 in a similar manner and with the aid of a signal of frequency (say) 4000 controls the loud-speaker 20. Filters 6, 6a cut out the signal frequencies from the speech currents fed to line and prevent the signal currents from reaching the loud-speakers.

Title: Improvements in and relating to the manufacture of gas from coal and like carbonaceous material
IPC: C10J3/46
Filed: 1946-06-19
Abstract: 647,706. Gasifying solid carbonaceous materials. BAMAG, Ltd., LAIDLER, K., and WISNIEWSKI, J. June 19, 1946, No. 18419. [Class 55 (i)] ] Gases comprising mainly hydrogen and oxides of carbon are continuously produced by contacting disintegrated carbonaceous material with gases containing oxygen and steam in a reaction zone in which the gases under 5-50 atmospheres pressure move upwardly at a velocity causing the material to "float." The gases may be injected at spaced points and external heating or cooling applied through the producer walls to control localized reaction temperatures. Part of the product gases may be recycled to serve as a carrier for the material or to take the place of nitrogen when oxygen instead of air is employed in generating a nitrogen-free water gas. A mixture with a low methane content for ammonia synthesis is obtained by introducing steam and air enriched with oxygen at a pressure preferably between ten and twenty atmospheres into a chest 15 'and thence through passages 14 into a reaction shaft 1, fines of lignite, brown or bituminous coal, low temperature coke &c. being fed through a screw 4 near the base. Product gases escaping through an outlet 28 are preferably cleaned and treated to convert carbon monoxide to dioxide and remove it before reduction of pressure. Secondary air or oxygen may be introduced through pipes 25, 26. The fuel is introduced at the upper end of the shaft of a producer, Fig. 4, suitable for generating gas of high calorific value, the gas velocity at the level of the feeder screw being slightly above that of the smaller particles of material which are carried into a separating chamber 29. Fly ash descending a pipe 33 may have residual carbonaceous material burnt out by injection of oxygen through pipes 34, the ash being discharged molten and quenched as by water, steam for use in the process thereby being generated. Specification 558,879 is referred to.
