Patent GB-1017375-A (GB)
Title: Improved phosphonitrilic chloride process
IPC: D06M11/68
Filed: 1963-08-09
Abstract: Phosphonitrilic chloride polymers are produced by reacting gaseous HCl with gaseous NH3 below 150 DEG  C. in an inert solvent to form a dispersion of NH4Cl, adding PCl5, and heating, preferably under reflex at 100-150 DEG  C. with agitation.  The PCl5 may be dissolved in the same solvent and added over 2-4 hours, dropwise or in batches. Polymerization may be catalysed by anhydrous metal salts, e.g. CoCl2, AlClt, MnCl2, CuCl2, SnCl4, MgCl2, ZnCl4, TiCl4.  The polymeric solution is then filtered, evaporated at low temperature under pressure, dissolved in (50-70 DEG  C.) petroleum ether, filtered, and evaporated.  The solvent may be mono-, di-, or tri-chlorobenzene, benzyl chloride, chloroform, carbon tetrachloride, phosphorus oxychloride, tetrachloroethylene, or sym.-tetrachloroethane.  A comparative example describes ball-milling of NH4Cl in monochlorobenzene before reaction.  NH4Cl produced in dispersion has an average particle size of 1-2 m  and a surface area of 2.6 x 104 cam2/gm.

Title: Improvements relating to scanners for image reproduction systems
Inventor: WILBY WILLIAM PETER LANHAM
IPC: H04N1/409
Filed: 1966-07-14
Abstract: 1,125,749. Image reproduction by scanning. CROSFIELD ELECTRONICS Ltd. 14 July, 1967 [14 July, 1966], No. 31638/66. Heading H4F. A cathode-ray tube flying-spot scanner 3, which scans an original image 5 to produce signals by a photo electric cell 7 which modulate a light source 14 exposed to a light sensitive sheet 15 on which a reproduction of the original is reproduced, is periodically varied in focus under control of oscillator 24 so as to cause the output signal of the photo-electric cell to consist of components representative alternately of "unsharp" and "sharp" image scanning. The components are separated to channels 10-11 by a distributor 9 controlled by oscillator 24, the distributor also including means to smooth the components to continuous signals, and then pass to a computer 12 in which the signals are recombined after first inverting the "unsharp" signal so as to bring about "unsharp masking", whereby the apparent definition of the reproduced image is improved. As illustrated, light sensitive sheet 15 is carried by drum 16, the scanning circuits 1 of cathode-ray tube 3 being synchronized with the drum rotation by a photo-electric pulse generator 19-23 associated with the drum shaft. Reference is made however to alternative arrangements which use an oscillating table in place of drum 16 or a cathode-ray tube display and exposing unit. Reference is also made to the application of the invention to colour reproduction where the light from image 5 is split into red, green and blue components which are detected by separate photo-electric cells. In carrying out the invention each cell signal is separated into "sharp" and "unsharp" components by a distributor 9 controlled by oscillator 24.
Patent GB-974643-A (GB)
Title: A process for the production of molecular sieve granules
IPC: B01J29/70
Filed: 1962-08-17
Abstract: Silica bonded molecular sieve granules are produced by stirring a powdery molecular sieve zeolite with an aqueous silica sol to form a flowable suspension of pH 8.0 to 10.0, mixing this with a suspension of finely divided magnesium oxide in water in an amount of 0.1 to 3% by weight of magnesium oxide related to the dry weight of the granules, and distributing the liquid gellable mixture in the form of drops in a water-immiscible liquid until sol-gel conversion occurs. The flowable suspension may alternatively be obtained by mixing the powdery zeolite with water or a part of the silica sol to form a crumbly mass which is then stirred with the aqueous silica sol, or remainder of the sol. The sol may have a specific surface area, according to B.E.T. of 150 to 400 m.2/g. and containing not less than 10% by weight of silica.  The granules, after being completely dehydrated, contain at least 50%, preferably 70 to 90%, by weight of zeolite. The granules may be subjected to ion exchange with a solution of an alkaline earth metal salt or heavy metal salt, to convert it, e.g. to the calcium form.  Specification 777,232 is referred to.

At the commencement of forming the bobbin a roller 48 on a pawl 43 bears on the point a of the periphery of the disc 39, the pawl 43 occupying its lowest position and a tooth 42 thereon engaging a nose 42<1> on the hub of the crank 27 thus supporting the weight 45, the belt being on the smaller pulley. As the bobbin grows, the wheel 35 is rotated and sets up a rotation of the disc 39 the roller 48 being raised by the part b of the disc 39 thus releasing the crank 27 which is moved to the position 53 thereby shifting the frame 22 and the belt to the larger pulley. The pawl 43 is held lifted over the range b - - c, when, if it is desired to run on the smaller pulley during the building of the nose, the pawl 43 is allowed to fall again to the original position, thus holding the crank 27 when the belt has been moved on to the smaller pulley. If the maximum speed is to be retained while building the nose, the pawl 43 is held lifted over the range b - - d. The gear ratios are selected so that during the building of the bobbin the disc 39 does not turn through more than 320‹. A modified arrangement is shown in Fig. 4.
