[Also in Division G2] In an optical processor of Doppler returns in a radar on a moving platform, a record 1 of radar echoes in the form of a one dimensional zone plate is moved in front of a laser beam, a conical lens system 17 moves in synchronism with the record, an anastigmatic lens system 11 brings the light into focus in its back focal plane with the displacement of the spot from the axis representing the Doppler frequency, and an astigmatic lens system 13 ensures that a Fourier analysis has an output plane coincident with the image plane for the range axis on screen 9 (which is a range-velocity display). After an appropriate processing time system 17 reverts rapidly to its original position and the cycle continues. Clutter is reduced. By utilizing an offset frequency at least twice as large as the maximum Doppler frequency, approaching and receding targets are differentiated. A conical lens system is defined.

Abstract: 547,907. Dyes; printing. DURAND & HUGUENIN AKT.-GES. Dec. 30, 1940, No. 18199. Convention date, Dec. 28, 1939. [Classes 2 (iii) and 15 (ii)] Mordant dyestuffs capable of withstanding hydrosulphite under the conditions of discharge printing are produced by reacting a nitrous compound of a dialkylaniline substituted in the meta position with a product obtained by condensing one molecular proportion of 2- naphthylamine-5-sulphonic acid or 2-naphthol- 5-sulphonic acid with at least two molecular proportions of an aminosalicylic acid, in the presence of a diluent and a mineral acid.- The latter causes the loosely bound aminosalicylic acid of the condensation product to be eliminated and this may be effected as a separate step before the reaction with the nitroso compound. Overprinting with pastes containing hydrosulphite upon chrome printed natural and cellulose artificial silk is mentioned. In examples, nitroso dimethyl metachloraniline and nitroso diethylmetatoluidine hydrochlorides are reacted, in the presence of alcohol and hydrochloric acid with a product obtained from 2-naphthylamine-5-sulphonic acid (1 mol.) and p-aminosalicylic acid (2 mols.).

Title: Improvements in or relating to the production of pulp from wood
IPC: D21C3/22
Filed: 1936-07-02
Abstract: <PICT:0477543/IV/1> Waste liquors from processes for the production of wood pulp by the soda, sulphate, or sulphite digestion methods, are first concentrated by evaporation, the amounts of reactive ingredients are made up to approximately their original weight, and the liquors are then used for further extractions.  Preferably, the evaporation proceeds to such an extent that the concentration of the reactive ingredients in the regenerated liquor is the same as that in the original solution.  When the concentration of the ligneous constituents has reached, e.g. 500 g. per litre, a portion of the liquor is withdrawn for recovery of the salts, e.g. by concentrating and burning, and the heat liberated conveniently used to generate steam used in the process.  In an example, pulp and waste liquor is discharged from a digester I, II, or III into a diffuser 1 from which the liquor is washed out into a container 4.  From 4 the liquor may be passed either to evaporators C, D<1> and D<2>, or through pre-heater B into one or other of the digesters.  Concentrated liquor from the last evaporator D<2> is collected in a container 7, from which part of the liquor may be withdrawn through pipe 13 for recovery of salts.

The electrodes may be manufactured by blending and compacting comminuted component powders of between 1-8 microns in size, and sintering for ¢ to 20 minutes, this time varying inversely with temperature. Alternatively, cadmium oxide may be incorporated into pre-shaped silver electrodes by impregnating them under partial vacuum, by contact with a concentrated solution of cadmium salts such as the sulphate, nitrate, chloride acetate or organic or inorganic compounds soluble in water. The coated electrode so formed is treated in a warm solution of an alkali metal hydroxide such as sodium or potassium hydroxide of 25-45% concentration. Excess water and cadmium hydroxide is removed from the electrode which may be dried at 95 to 105 C. until constant weight is achieved. A battery comprises a casing 2, a plurality of positive and negative electrodes 11, 12 manufactured as above, and layers of porous and/or semi-permeable separating layers 13.

Abstract: 1420621 Wagon tipplers STRACHAN & HENSHAW Ltd 16 April 1973 [20 April 1972] 18476/72 Heading B8E A wagon tippler comprises arcuate end frames 2 connected to the ends of a wagon receiving track 20, which is supplied with a wagon by side-arm charger 50 having a coupler arm 52, and means for rotating the end frames to discharge the wagon. The end frames 2 rest on rollers 4 and are rotated by pinions 10 which engage racks 12 on the frames. Each end of the track 20 is pivoted, with play, to a lug 38 on a J-shaped beam 24 one end of which is pivoted at. 30 to a link 26 pivoted at 28 to the respective end frame 2, and the other end of which carries a roller 31 which, in the start position of the tippler, rests on a shoulder 32 on the end frame. The end track 20 also carries rollers 40, 42 which rest on profiled blocks 44, 46 to support the track prior to rotation of the tippler. During initial rotation, the rollers 40, 42 run on the blocks 44, 46 to tilt the wagon against pads 58 carried by a beam 27 connected to the beams 24 so as to cause the rollers 31 to run along tracks 34 on the end frames 2 to position the wagon against pads 62 on a support 64 pivoted to a beam 18 secured to the end-frames 2. With the wagon thus held rotation is completed. In a second embodiment, Fig. 5, the pads 58 are secured to a beam 76 secured to the endframes 2, and the support 64 is pivoted to a beam 80 carried by arms 82 pivoted to the endframes and connected to levers 84 carrying followers 86 which engage ramps 88 to hold the support 64 in a raised position. During rotation of the tippler, the followers 86 move along the ramps 88 to allow the pads 62 to descend on to the wagon. At the same time pivotal locking pawls 100 on the end frames rotate and engage a rack 104 on each arm 82 to hold it against movement caused by the weight of the inverted wagon. On return of the tippler the pawls are released by ramps 106.
