Abstract: 157,216. K³hn, H., and Hanfstaengl, F., [Firm of]. Nov. 13, 1915, [Convention date]. Photo-mechanical printing-surfaces.-To enable photographic copies to be made of any object with accurate reproduction of the gradations of tonevalues both as to light and shade two printing forms or layers are used, one being over exposed and the other under exposed, these two being complementary to each other in furnishing a print with all shades in their true values. Theprinciple is applicable for single or multi-colored light printing or for oil or bromide-oil reprinting with a plurality of forms. The forms for printing may be obtained from the same negative by printing with different durations. Where large contrasts between high lights and shades exist two negatives face to face may be exposed simultaneously separated by thin filter to get under and over exposed negatives. Diapositives from these may be used for printing an enlarged negative from which the printing forms for use are made by over and under printing.

Rectifiers. - The fractional condensation of mineral oil &c. vapours is effected by passage through a series of cooled dephlegmators in which condensate obtained in each dephlegmator is reheated by the incoming vapours. The dephlegmator consists of a vertical casing a, divided by horizontal plates c, d to form a chamber b into which vapours are fed from an inlet e. The vapours rise through tubes f, the upper ends of which are slotted and covered by perforated caps, and after passage over tubes v through which cooling-medium is circulated pass to an outlet s. Condensate falls through packing r down an inclined plate p and on to the plate d across which it passes in a tortuous path round baffles g. Steam may be injected into the condensate through a perforated pipe i. The condensate passes down a pipe k to the chamber l and to an outlet m.

Title: Magnetic recording
IPC: H04L25/49
Filed: 1973-01-12
Abstract: 1357083 Recording system INTERNATIONAL BUSINESS MACHINES CORP 12 Jan 1973 [24 Jan 1972] 1657/73 Heading G4C In a transformer coupled magnetic recording system for recording a stream of binary bits, the bits are segmented into blocks of specified lengths, each block having an additional bit inserted, chosen to reduce A.C. coupling distortion. As described in which recording is by the NRZ method, a digital sum of the bits in each block is computed when a one and zero bit is inserted, the block having the minimum sum being selected. The apparatus comprises a primary shift register (Fig. 9A), secondary shift registers A, B (Fig. 9B), preset shift registers A, B (Fig. 9C) and an output shift register (Fig. 9D), each having two cells for each bit. Initially a byte from the primary shift register is entered into the lefthand bit positions of the secondary shift registers A, B, the right hand bit of these shift registers being set to 0 and 1 respectively. The contents of the secondary shift registers are then sequentially transferred to the process shift registers A, B, the transferred "1" bits from the secondary shift A, B also being fed to triggers 234, 236 respectively, the transferred 0 bits being fed to gates 246, 248 respectively so that each 1 bit results in the direction of count of 7 bit process counters A, B initially set to their mid value being changed and each 0 bit results in the incrementing or decrementing of the associated counter. After all the bits have been transferred the contents of the processed counters A, B are XORed with the quantity 0111111 i.e. the mid value and compared, the comparator enabling the transfer to the output shift register of either the contents of processed shift register A if B is greater than A or of processed shift register B if A=B or A greater than B. The minimum sum in one of the counters is then also entered into the other counter. The system is mainly controlled by clocks O, I, P. The clock O controls the entry of the contents of process shift registers A, B into the output shift register and the sequential feed out of this register. The clock I controls the reading in of the bits from the primary shift register and the clock P controls the transfer of the data between the primary register, secondary and process shift registers and the comparison circuitry.

Title: Devices for effecting auto-destruction of gyratory missiles
IPC: F42C15/22
Filed: 1978-01-16
Abstract: The self-destruction device for spinning projectiles has a blocking part (14) and a release part (24) which, constructed in the form of a bracket, grip a spring-loaded firing pin (20) and can pivot about a common shaft (12). Their centres of gravity (G1, G2) are located, for example, in the quiescent state in such a position that the blocking part (14) blocks the firing pin (20). The releasing part (24), which is subject to the force of a spring (26), is pivoted with a stop surface (30) in the direction of a cam (32) on the blocking part (14) when the centrifugal force reduces after the spinning projectile has been fired, so that the blocking part (14) is driven and the centres of gravity (G1, G2) are displaced. At the same time, the firing pin (20) is released. The firing pin (20) is provided with a flange (18) by means of which it can be locked in the prestressed position by means of the blocking part (14). <IMAGE>

A preferred catalyst is molybdenum sulphide deposited on charcoal, the molybdenum sulphide comprising from 10-80 per cent. and preferably 15 per cent. of the mixture.  The apparatus used to carry out the invention comprises a reactor 12 into which is passed a mixture of mono-nitro-hydrocarbon and hydrogen from lines 5 and 6 respectively via heat exchanger 8 and preheater 10.  The products pass down the reactor 12 through catalyst chambers 13a, 13b, 13c and 13d.  In accordance with the invention the reaction temperature is controlled by admitting part of the nitro compound from the storage chamber 1 via lines 4 and 25 where it is contacted with water added through line 26, and admitted into reactor through a pluralty of points 29a, 29b and 29c, preferably in the spaces between the catalyst beds.  Water withdrawn from reactor 12 along with the products of reaction is separated in the separator 20, withdrawn through line 23 and recycled to the water inlet 26.ALSO:Aromatic amines are prepared by the reduction of mononitro aromatic hydrocarbons with hydrogen in the presence of a hydrogenation catalyst, wherein the reaction temperature is controlled by introducing a mixture of the nitro hydrocarbons and liquid water into the reaction zone at a plurality of points and immediately vaporizing the water under the reaction temperature.
