Title: Character reading system and character carrier therefor
IPC: G06K19/04
Filed: 1972-02-11
Abstract: 1380963 Character recognition systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Feb 1972 [16 Feb 1971] 6551/72 Heading G4R A document, which may carry hand-written characters to be read by a character reading machine, includes a pre-printed area which if marked by the writer causes the output of the reader to be fed, or alternatively not to be fed, to a data processor. The area is separate from the regions in which the characters are written. The marking may in the former case take the form of a scribble made by the writer in the area, or of a tear-off portion. A detector, which may precede or follow the reader, detects the presence of the mark and connects the reader to the processor. In, for example, the absence of the mark the document is processed by being read visually and the characters transcribed into a form suitable for feeding to the processor. The document may carry an additional area which the writer may mark. Detection of this mark will prevent the output of the reader from being passed to the processor, whether or not the other area is marked.

Title: Improvements in or relating to the manufacture of gelatine blasting explosives
IPC: C06B23/00
Filed: 1946-03-14
Abstract: 610,850. Blasting gelatine explosives. FORDHAM, S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 14, 1946, No. 7969. [Class 9 (ii)] Consists in a process for the production of gelatine blasting explosives which comprises mixing water-wet nitrocellulose soluble in nitroglycerine with one or more liquid explosive nitric esters in the presence of an anionic or non-ionic organic wetting agent capable of assisting the wetting of nitrocellulose by water, such as sodium dibenzyl sulphanilate, the sodium -salt of isopropyl naphthalene sulphonic acid, or polyglyceryl ricinoleate. The wetting agent preferably 0.2 to 2 per cent of the weight of dry nitrocellulose present, may advantageously be added to the water of the water-wet nitrocellulose, or, more particularly in the case of a non-ionic organic wetting agent, to the liquid nitric ester or esters, and the initial mixing of nitrocellulose and nitric ester or esters is preferably carried out in absence of any gelatinization accelerant. In an example, blasting soluble nitrocellulose is given a final wash with a 1 per cent aqueous solution of sodium isopropyl naphthalene sulphonate during manufacture and is then pressed to 28 per cent moisture content. The lumps are broken down and the water-wet nitrocellulose is mixed to a smooth gel with nitroglycerine without precautions such as blending with inert material, and this smooth gel is suitable as a base for blasting explosives. Specifications 23846/02, 14825/03, [both in Class 9], 586,224 and 596,279 are referred to.

Abstract: 716,214. Fluid-pressure servomotor-control systems. BOULTON PAUL AIRCRAFT, Ltd. March 30, 1953 [March 28, 1952], No. 7982/52. Addition to 716,184. Class 135 In a fluid-pressure system for operating the flying controls of aircraft as in the parent Specification, the displacement of the delivery controlling member of the pump supplying the fluidpressure motor or jack which actuates a control surface is limited by a variable stop co-operating with an abutment movable with the master element of the fluid-pressure operated relay that actuates the delivery controlling member. The pilot's control acts through a differential gear. Two plungers 7 arranged side-by-side and each coacting with a respective lever 13, 14 through a spring-loaded rod 11 are subjected to the pressure at either end of the fluid-pressure motor so that a lever 26, fixed to a shaft 23 to which both the levers 13, 14 are also fixed, takes up a position dependent upon the working pressure in the motor irrespective of the direction of movement of the motor. The lever 26 carries a stop in the form of a roller 28 which coacts with a V-shaped notch 29 in a member secured to the master element of the relay whereby the displacement permitted the master element and, therefore, the delivery controlling means of the pump is progressively decreased as the working pressure of the motor operating the control surface increases. Alternatively, the V-notch may be carried by an arm rocked by the plungers, or the plungers may operate directly a member carrying either the stop or the V-notch. Specification 577,018 also is referred to.
