Title: Improvements in planographic printing
IPC: G01J3/42
Filed: 1940-07-30
Abstract: 541,672. Printing-surfaces. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. July 30, 1940, No. 12355. Convention date, Jan. 4. [Class 100 (ii)] Planographic printing plates, such as described in Specifications 493,135 and 496,421, and comprising a printing face of cellulosic material secured, e.g. by a waterproof adhesive, to a flexible backing sheet which may be impregnated with a waterproof adhesive, have a printing surface in which the lateral water diffusion rate is less than 25 millimeters in four hours. Such a low rate may be obtained by oxidation of the printing surface e.g. by heat treatment in air or with anhydrous chlorine gas or by exposure at ordinary temperature to ultra-violet light. To prevent contamination of the cellulose surface by prolonged contact with the backing sheet when the composite material is being made and wound into roll form, the time of such contact is prevented from exceeding one hour by stopping the winding operation after thirty minutes, cutting the webs, and attaching the leading end of the incoming web and the trailing end of the wound web with the cellulose in contact to a new winding roll on which the combined webs are wound for not more than a further thirty minutes. When the webs are cut into sheets they are stacked in with the cellulose faces of adjacent sheets opposed to one another and in slightly concave form to allow ready access of air to those faces. The cellulosic material preparably has a smoothness of at least two seconds by the Bekk smoothness tester and an opacity of not more than 0.6 for ordinary parchment or more than 0.45 for amyloid parchment as measured by the Bauson and Lomb opacimetei.

Title: An improved catalytic process for the production of normally liquid branched chain hydrocarbons
IPC: C07C2/58
Filed: 1941-09-26
Abstract: 556,712. Hydrocarbons. STANDARD OIL DEVELOPMENT CO. Sept. 26, 1941, No. 12478. Convention date, Oct. 5, 1940. [Class 2 (iii)] A process for the production of branched chain hydrocarbons boiling within the motor fuel boiling range by reacting isoparaffins with olefines is effected at a temperature between 375 and 950‹F., at a pressure above 500 pounds per square inch in the presence of an oxide or sulphide of a metal of Group 5, 6 or 7 of the Periodic Table and a small amount of water or hydrogen sulphide. The catalysts may be supported upon carriers. Examples of the latter are : natural or acid treated clays, alumina and silica gels, bauxite, fuller's earth, bentonite, kieselguhr, pumice, montmorillonite, marsil, tonsil, porcelain and activated floridin and charcoal. The isoparaffins and olefines may be derived from cracking units of a refinery, field butanes which have been subjected to isomerization and/or partial dehydrogenation, refinery stabilizer bottoms and stabilizer overhead gases. The process may be continuous, the catalyst being regenerated by treatment with oxygen or sulphur. After burning off the carbonaceous material, a sulphide catalyst may be dissolved in ammonium hydrosulphide and treated with hydrogen sulphide. The resulting ammonium thiometallata is decomposed with sulphuric acid and the sulphide finally heated in the presence of hydrogen. In examples, isobutane is reacted with propylene in the presence of molybdenum oxide impregnated alumina gel and about 11 per cent. of water in a bomb. Another catalyst is prepared by homogenising silica hydrogel and alumina and drying and heating after adding ammonium vanadate. Specification 543,968 is referred to.

Abstract: 1,161,536. Recording apparatus. PERKINELMER CORP. March 20, 1967 [March 30, 1966], No. 12993/67. Heading G1J. A chart recorder capable of using both a stationary chart and a moving strip chart comprises a pen mechanism 24 movably mounted on a pen carriage for transverse movement across the recording chart and a driving mechanism for producing both longitudinal movement of the pen carriage in one direction while the chart is stationary and longitudinal movement of the strip chart in the opposite direction while the pen carriage is stationary. The pen 27 is attached to a bracket 28 which slides along a rod 30, the bracket being secured to a belt 46 driven by a motor 53. The motor also drives a potentiometer 54 which supplies to a conventional servocontrol a signal proportional to the position of the pen. For a fixed chart 19, movement of the pen carriage is effected by a belt 112 attached to the pen carriage and driven by a motor 92 via gear wheels 98, 90 and a shaft 86. For use with a moving strip chart 18, the pen carriage is fixed in position and an arm 104 is moved so that gears 100, 144 engage. The gear 144 rotates a hollow shaft 88 which in turn drives belts 136, 138. Projections 150, 152 on the belts engage perforations 146, 148 in the strip chart to move the chart. The recorder may also be used as an X-Y recorder, in which both the ordinate and the abscissa values vary in a non linear manner, by supplying a varying signal to the motor 92. For rapid or slow abscissa movement the pen carriage and strip chart may be moved in opposite or the same directions respectively.

Abstract: 1499312 Immunizing against jamming BOLKOW GmbH 31 March 1964 [9 April 1963] 13247/64 Heading H4L In a system for the transmission of signals (such as A, Fig. 2) in which the received signals cannot be affected by third party interference, the signal A is fed to a converter 2 where it is divided into a number of sub-ranges #K and a pulse of constant amplitude and duration is produced wherever the signal crosses a range line g, this pulse being positive for a rising signal and negative for a falling signal. The output of converter 2 is shown at B, Fig. 2, the individual pulses coalescing to form a pulse of longer duration when the signal A rises or falls at its maximum rate. The signal B is separated (16, 17) into its positive and negative portions which are supplied to respective channels I, II. The signal in channel II is reversed in polarity (4), and both signals C, D are then supplied via respective modulators 3, 5 to a transmitter 6. The signal radiated by aerial 14 is received by an aerial 15 of a receiver 7 and is conveyed to a filter (not shown) which separates the impulses C and D and passes them to demodulators 8, 9 in channel I 1 , II 2  to become signal C 1  and D 1  respectively. The signal C, is supplied directly to an integrator 11 whereas signal D 1  previously has its polarity reversed in a reversing amplifier 10 where it becomes a negative signal E. The integrator 11 produces an output signal F from the sum of the signals C, and E. Thus any jamming action will be cancelled out in the integrator due to the reversing amplifier 10.
