Title: Production of nitric acid
Inventor: NEWMAN DANIEL JOSEPH
IPC: C01B21/26
Filed: 1969-03-10
Abstract: 1,243,451. Nitric acid. CHEMICAL CONSTRUCTION CORP. 10 March, 1969 [14 March, 1968], No. 12587/69. Heading C1A. Concentrated nitric acid is produced by cooling to between - 40 and 15 C. a process gas stream containing nitrogen oxides and water vapour, contacting the residual gas stream with water or an aqueous solution of nitric acid in a first absorption zone to form aqueous nitric acid, passing air first through the condensate to strip nitrogen oxides and oxidize nitric oxide to nitrogen dioxide and then, in a second absorption zone, through the aqueous nitric acid formed in the first zone and withdrawing the concentrated acid. The gas stream may be initially cooled to condense dilute acid which is passed to the second absorption zone. In Fig. 1, the gas stream is cooled in condenser 10, the first absorption zone is tower 13 and the second absorption zone is section 36 of tower 35. Stripping and bleaching occur in towers 24 and 28. Air may be passed up through the first absorption zone so that nitrogen dioxide is formed which may be absorbed. The gas stream may be divided into two portions, one proceeding directly to the first absorption zone the other being cooled in condenser 10. The nitric acid obtained from the first absorption zone normally contains 50 to 65% by weight of acid, and it may be divided into two portions, one being withdrawn as product and the other proceeding to the second absorbing zone. The tail gas stream from the second zone may be passed to the first zone. In a modification of the process the stripping and absorption of the condensate are effected at a pressure  between 3 kg./sq. cm. and 100 kg./sq. cm. In a second modification, after initial condensation, the dilute acid obtained is distilled to obtain a 50 to 68% nitric acid solution which is passed to the second zone. The final product acid may also be distilled, the vapour being essentially anhydrous acid, and the remaining acid being 68% nitric acid which may be recycled to the second zone. Other modifications of the process are described.

Title: Television cameras
IPC: H04N5/376
Filed: 1975-03-26
Abstract: 1501017 Television SONY CORP 26 March 1975 [29 March 197422 July 1974] 12700/75 Heading H4F A solid state monochrome television camera contains an array 10A, Fig. 1, of photodetectors formed in a silicone substrate 10S of a charge coupled device (C.C.D.). Charges are formed in the array cells 1 1-1  ... 1 m-n , when light from an image 14, Fig. 3, is focused by lens 15 on to the CCD 10. The light sensitive location on alternate lines are in antiphase, however, this effect is produced by marking the in phase detectors in a suitable manner. The resulting charges spread out under the marks and produce an in phase distribution of charge. The charges are transferred by three phase clocks # 1  to # 3  into a second storage array 10B, Fig. 1, identical to array 10A but optically shielded. The stored charges are transferred line by line to a shift register 10C for sequential output of the picture signal S O S E  corresponding to odd and even lines respectively, of the image. The alternate odd and even line signals S O  and S E  are passed to an adder stage 25 with the even line signals S E  being delayed by half a horizontal element scan period to effect a phase inversion thereof. Figs. 5A and 5B show the odd line signal frequency spectrum and the even line spectrum with phase inversion. These signals are passed to adder 29, Fig. 3, via a one line delay 28 and directly along a by pass loop, the resultant signal occurring at output terminal 31 contains only the D.C. components S DC , Fig. 5C since the antiphase side band components S SBO  and S SBE , Figs. 5A and 5B respectively cancel out. In another embodiment Figs. 7 and 8 (not shown) the low frequency D.C. components which do not lie in the side band regions are filtered prior to cancelling the side band components by combining the antiphase versions thereof, and then recombined with the remaining higher frequency D.C. components for output. This improves the vertical resolution of the camera. In a further embodiment three such cameras including respective colour filters are combined to form a colour camera. Another embodiment provides a colour camera requiring only one C.C.D. 10, Fig. 9, in front of which a patchwork colour filter 40, Fig. 10, is disposed. The side band components S SBO , S SBE , Fig. 11D are extracted from the outputs S O  and S E . These are delayed by one line period and recombined by adder 45 and subtractor 46 with the CCD outputs S O , S E , yielding: as output from adder 45 the D.C. components R + B + G, Fig. 11E, since the antiphase nature of the side band colour components indicated in Figs. 11F and 11G cause cancellation thereof; and as output from subtractor 46 the side band colour components which are suitably demodulated 48, 49 and matrixed 47 to provide an NTSC type signal on output terminals 50 to 52. As an alternative a photo diode array may be used in which case the relative line phase shift is inherent obviating the need for the half element scan period delay in signals for alternate lines.

Title: Improvements in or relating to detergent compositions in bar form
Inventor: WARD NORMAN ERNEST
IPC: C11D1/12
Filed: 1960-08-31
Abstract: A detergent composition in bar form comprises a mixture of a preformed soluble soap and at least one preformed alkaline earth metal, magnesium, zinc or aluminium salt of an amide linked sulphuric acid derivative of general formula R.CO.NH(CH2)nSO4H, in which R.CO. is a C10-18 fatty acyl radical, and n is 1-3.  The mixing of the soap and salt is carried out under conditions such that exchange of cations does not take place, i.e. with insufficient water to make the mixture fluid, or if more water than this is present the mixing is achieved quickly and the product dried immediately.  The soap may be a conventional alkali metal soap, e.g. one derived from a mixture of tallow with coconut or palm kernel oil, while a suitable salt is calcium lauryl monoethanolamide sulphate.  A small proportion of free saturated C10-18 fatty acid may be present, as also may be perfume, colour, opacifiers, superfatting agents, and germicides.

Abstract: 838,396. Rolling. MOELLER & NEUMANN G.m.b.H. April 23, 1957 [April 23, 1956], No. 12967/57. Class 83 (4). In a continuous rolling mill, the stands have vertical and horizontal overhung roll pairs at opposite ends and one roll of each pair is driven from a common driving shaft. In one example vertical overhung rolls 1, 2, Fig. 6, and the horizontal overhung rolls 3, 4 are adjustably mounted at substantially the same height in a common housing 18 and are driven from a common shaft 7 in the base from a motor (not shown) which may be connected at either end through shafts 5 and couplings 6. The vertical roll 1 is driven through gears 12, 13 and bevel gears 14, 15 and the horizontal roll 4 is driven through gears 9, 10, 11. Either pair of rolls may be driven independently by disconnecting a clutch 8. The idling rolls 2, 3 are driven by auxiliary motors 16, 17 at speeds slightly above that corresponding to the speed of entry of the work. The units may be arranged side by side, Fig. 1, for driving from a common motor or may be staggered, Fig. 3, for driving from separate motors. The unit may also be arranged in line, Fig. 5, for continuous rolling through the stands on one side only, the stands on the other side being disconnected from the drive. The units may be turned round through 180 degrees so that vertical or horizontal rolls may be used as required. In this example the roll pairs are offset from and disposed on opposite sides of the driving shaft so that the position of the motor remains unchanged when the units are turned through 180 degrees.
