[Class 146 (ii)] [Also in Group XX] Documents, drawings, and the like are coded and de-coded by screening an original with one or more apertured screens, transferring the exposed section through a further apertured screen on to a light-sensitive surface, and then altering the relative positions of the original, the light - sensitive surface, and the screens until all the sections of the original have. been transferred into relatively different positions on the light-sensitive surface. the original a is divided up into sections preferably squares, and a screen b is provided with apertures corresponding in shape to the sections of the original and so arranged that there is an aperture in each line and column; this arrangement of apertures is preferably duplicated on the screen to facilitate adjustment. A second screen d is also provided with apertures preferably joined together to form a straight slot equal in width to the width of the sections and in length to that of the original. The sensitive surface c is located beneath this second screen. The screen d is first set to expose a particular column on the surface c, the screen d is set to the desired adjustment on the original a, and the screen d and original are then moved together until the exposed column on the surface c is filled. The screens are then adjusted relative to the original and surface c and the process repeated until the whole of the original has been transferred. To complicate the code obtained still further, the resultant may be rotated through a right angle, and the coding-process repeated. De-coding is effected by the reverse operation. A device is described comprising a light-tight box in which the screen d is secured, and the screen b, original a and surface c are carried by slides movable singly or in unison and controlled to make the required movement according to the spacing of the apertures in the screen; lights are arranged above the slot in the screen d. In a modification, the original a and surface c and, if desired, the screen b, d are wound on rollers.

Filed: 1938-12-09
Abstract: 522,575. Preventing corrosion. ELECTROLUX, Ltd. Dec. 9, 1938, No. 35974. Convention date, Feb. 2, 1938. [Class 123 (i)] Hermetically sealed refrigerating apparatus is provided with a reserve store of a chromate for counteracting corrosion. The store is rendered accessible by corrosion products which attack a protecting metal plate. A boiler 10, heat exchanger 13, and absorber 14 are connected in known manner, the lower part of the absorber forming a storage space 16 for rich solution. A container 26 is divided by thin plates 27 of aluminium, zinc, or their alloys, into three spaces 28 containing ammonium chromate. The solution is originally charged with sodium chromate to prevent corrosion, and by reduction of the chromate, sodium hydroxide is gradually formed and attacks the plates 27. Ammonium chromate is then dissolved, and sodium chromate is again formed. Instead of employing a protective metal plate, the chromate may be embedded in, or mixed with, a substance such as a silicate, so that the chromate is only reached when the sodium hydroxide concentration reaches a predetermined point.

Title: Isomerised hop extracts
IPC: C12C3/12
Filed: 1971-08-04
Abstract: 1423129 Hop extracts BUSH BOAKE ALLEN Ltd 2 Oct 1972 [4 Aug 1971 15 March 1972] 36554/71 and 12064/72 Heading C6E A method for isomerisation of hops alpha acids involves contacting a solution of a hop extract containing alpha acids (optionally in the presence of beta acids, hop oils and other extracted hop constituents) dissolved in a water-immiscible organic solvent with sufficient of an oxide, hydroxide or carbonate of magnesium, calcium, strontium, barium or zinc to form a solution of the corresponding salt of the alpha acids in the solvent, and heating the mixture sufficiently to form the corresponding salt of the iso-alpha acids. The preferred organic solvents are toluene, benzene, xylene and petroleum hydrocarbon, though others are also mentioned and exemplified. The rate of reaction is in some cases influenced by the presence of water. Thus, calcium hydroxide will react when used in conjunction with a toluene solution of hop extract without the addition of water, whereas magnesium hydroxide used under the same conditions gives only a slow reaction unless a trace of water is added. The iso-alpha acids are recovered from the water-immiscible solvent by redissolving any precipitate with addition of methanol and sufficient water to form a separate aqueous - alcoholic layer, acidifying the mixture with hydrochloric acid sufficiently to release free iso-alpha acids in the water-immiscible layer, separating off the aqueous alcoholic layer and then contacting the water-immiscible layer with potassium bicarbonate solution at a pH not above 8 which is sufficient to extract the iso-alpha acids as the potassium salts into the aqueous phase, but not the corresponding salts of the beta acids, hop oils &c. The isomerized alpha-acids or hop extracts produced according to the method may be added to wort or fermented beer for bittering.

Abstract: 943,517. Gas filters. P. G. VIGARD. Oct. 12, 1961 [Oct. 12, 1960], No. 36634/61. Heading B1T. Cleaning of each of a plurality of outwardflow open-ended gas filter sleeves 1, Fig. 3, stretched between upper and lower transverse partitions 4, 7 within a casing 1 to form a dustladen gas inlet chamber 5, a clean gas outlet 3 and a dust collecting chamber 8 is effected by imparting to the gas within each sleeve a velocity component parallel to the sleeve wall which is many times greater than the radial velocity component. As shown, a cylindrical imperforate core 11 is inserted within each sleeve thus forming a narrow annular flow path 12 having a tangential inlet formed by a volute 10. In a modification the flow is axial and the velocity is increased by recycling gas withdrawn from the dust collecting chamber 8, Fig. 5, through a duct 13 by a fan 14 which discharges through a duct 15 to the dust laden gas inlet duct 6. The exterior of each sleeve may be wound with an electrically earthed wire which in the case of ionized dust particles serves to coagulate them and thus assist their removal from the filter sleeve wall.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L21/24
Filed: 1960-10-28
Abstract: 942,070. Semi-conductor devices. NIPPON ELECTRIC CO. Ltd. Oct. 28, 1960 [Oct. 28, 1959], No. 36780/60. Heading H1K. A semi-conductor device is made by alloying aluminium to a silicon body in the presence of phosphorus so that a finely crystalline layer is formed between the recrystallized material and the metallic residue. The phosphorus may be incorporated in the aluminium or in the silicon body to which it is alloyed. In the former case the phosphorus may constitute 0.00-1% by weight of the aluminium but the preferred amount is 0.08%. Despite the higher segregation coefficient of phosphorus the preponderance of aluminium in the molten alloy ensures the formation of a PN junction when the silicon body is initially of N type. The fine crystalline structure adjacent the PN junction absorbs mechanical stresses and thermal stresses caused by the differing expansion coefficients of the silicon and the overlying silicon aluminium alloy. The formation of similar layers in alloy junctions formed between other materials is also envisaged.
