Abstract: 984,001. Rolling. STEELWORKS AUTOMATION Ltd. June 8, 1961 [June 8, 1960], No. 20108/60. Heading B3M. [Also in Divisions G3 and G4] An automatic control system for a multistand rolling mill comprises gauges for measuring automatically the width and temperature of a bar prior to entry into the mill and a computer responsive to the measurements for automatically adjusting the mill. The mill is previously set for rolling a bar of average dimensions, so that, after passing a roughing stand 13, the width thickness and temperature of the bar are measured, using gauges 17 and 18 and a pyrometer 16 respectively, and any difference between the actual values and the assumed ones are fed to a computer which appropriately alters the roll settings in the finishing stands F1 to F6. The assumed parameters are shown on dials 26-28, Fig. 2, and the adjustments to the stands are made in the ratio of the positions of the tappings L1-L6 of an auto transformer 52. The resistors R 2 , R 3  and R 5 -R 11  are adjusted for bars or strips having widely differing dimensions. A similar computer 19 adjusts the roll speeds of the finishing stands F1-F6. Digital computers are preferred to analogue ones where a large number of factors are to be controlled. The finishing train may be controlled to produce strip of substantially constant thickness using an automatic control system such as those described in Specifications 681,373 and 692,267.

Title: Improvements in automatic devices for controlling the pressure in flying suits designed to prevent "black-out" in aircraft pilots
IPC: F16K1/00
Filed: 1945-08-07
Abstract: 604,304. Valves. HYMATIC ENGINEERING CO., Ltd., (formerly HEYWOOD COMPRESSOR CO., Ltd.), JAY, J. B., and HUNT, J. A. Aug. 7, 1945, No. 20209. [Class 135] A valve for controlling automatically the inflation of a flying suit to prevent blackout of the pilot when making sharp turns or pulling out of a dive, comprises a casing a having an inlet o connected to the compressed air system of the aircraft and an outlet p to the flying suit, and a double-beat valve n of, e.g. moulded rubber, as described in Specification 597,103, [Group XI], and mounted on a spring-loaded carrier m, the.opening of which is controlled by a piston c carrying a weight b and secured to a rod d supported by a spring e itself supported by a spring-loaded piston f. Normally, the weight is held against the valve cover h by the springs, but when the acceleration of the aircraft normal to the direction of flight reaches, say, 2g, the piston c is moved against the springs until it contacts with and opens the valve n. The air pressure on the piston f reduces the upward thrust on the valve carrier m and thus permits rapid opening of the valve. Upon reduction of the acceleration, the valve closes and air is permitted to flow from the suit to the atmosphere through ports a<SP>1</SP>, c<SP>1</SP> in the casing and the piston c respectively. The valve is provided with a test push-button i.

Abstract: 335,969. Harvey, J. July 2, 1929. Harmonic analysis. -Apparatus calculates the co-efficients of the equivalent Fourier series having the same values at the 2n points in the range 0 # 2# as has the function f(x) at the same points. If the values of f(x) at the 2n points be yo, y1, y2, -y2n-1) then where r = 1, 2, 3, - - - -(n - 1). For calculating the value of the co-efficients a0 - - - an, b1 - - - bn-1 when 2n = 12, i.e., #/n = 30‹, the apparatus comprises twelve bars H<1> and twelve similar bars H<2> fixed radially to circular discs D supported axially on the bar V by the plate P. The bar V is fixed to the bar A, supported by knife edges, and carries the movable counterpoise C for adjusting the sensitivity of the apparatus. The bar A has fixed to it two similar arms B carrying scale fans S balancing with respect to the knife edges. Each bar H<2> carries movably a unit mass U, the masses, when in their zero position on the bars being balanced with respect to the knife edges by masses M on the bars H<1>. The unit masses are moved from their zero positions through distances y0, y1,--- y11, the bars H<1>, H<2> being rotated through 180‹ for negative values. For any coefficient ar, r = 0, 1, 2 - - - - - 6 the bars in order are turned so as to make angles 0‹, r x 30‹, r x 60‹, - - . - - r x 330‹, with a plane perpendicular to the knife edges, and masses are added to one or other of the scale pans to maintain the bar V vertical asdetermined by the coincidence of an index I, a prolongation of the bar V, with the zero of a scale F. When balance is thus obtained the moment of the weights of the unit masses U and the counterbalances M about the knife edges is [y‹ + y, cos (r. 30‹) + y2 cos (2r. 30‹) + - - - + y11 cos (11 r. 30‹)] i.e. 6ar or 12ar according as r = 1, 2, - - - - or 5, or as r = 0 or 6. The balancing mass in a. seale fan S is thus a measure of the coefficient ar. To obtain a coefficient br the operation is repeated with the bars H<1>, H<2> rotated through a right angle. For other values of n the bars H<1>, H<2> are suitably increased in number, so that there are 2n H<1> -bars and 2n H<2>-bars..

Title: A process for the preparation of ar-tetrahydronaphthylthioacetic acids
IPC: C07C309/25
Filed: 1920-07-10
Abstract: Tetrahydronaphthalene is sulphonated with chlorsulphonic acid at low temperatures when a mixture of the 1- and 2- sulphochlorides in about equal parts is obtained; the sulphochlorides are reduced by zinc dust and hydrochloric acid to the tetrahydrothionaphthols, which by reaction with chloracetic acid in alkaline solution yield the corresponding thioacetic acids, and these are separated by means of the different solubilities of their ammonium salts.  Examples of these processes are given.  The tetrahydronaphthylthioacetic acids yield tetrahydronaphthylthio indigos.  The Specification as open to inspection under Sect. 91 (3) (a) contains also the following subject-matter: The sulphochloride mixture is hydrolyzed by water to the sulphonic acids which are then separated by their different solubilities in chloroform; the sulphochlorides are converted by ammonia into sulphonamides which are separated by means of the different solubilities of their sodium salts in water; the sulphonamides may be hydrolyzed to the sulphonic acids, or converted into tetrahydronaphthols by fusion with alkalis.  The tetrahydrothionaphthols are converted into disulphides by air-oxidation of the ammoniacal alcoholic solutions.  This subject-matter does not appear in the Specification as accepted.

Abstract: 793,561. Valves. HUDSON MANUFACTURING CO., H. D. July 18, 1955 [Feb. 21, 1955], No. 20765/55. Class 135. [Also in Group XXVIII] Liquid under pressure, from a portable compression-sprayer, for example (see also Group XXVIII), enters an annular inlet-chamber 22 from a pipe 16 and when the pressure in the chamber exceeds that exerted by a spring 26, a diaphragm 23 with an attached rubber or resilient diaphragm valve 24 is forced outwardly, the valve 24 leaving its seat 25 so that liquid both enters a passage 35 and acts on the entire central area of the diaphragm 23 to maintain the valve 24 off its seat 25 until the pressure of the entering liquid falls below that of the spring 26, whereupon the valve 24 closes. The passage 35 opens into a recess 36 that communicates with an outlet chamber 45, having a port 49, by way of a tapered valve seat 41 in a partition 46; the seat 41 co-operates with a closure member 38 urged on to its seat by a spring 42 but normally held open by a spring 57 acting on the top of a metal diaphragm 53 that abuts an upstanding nose 39 integral with the member 38. Liquid in passage 35 therefore flows into the outlet port 49 and acts on the underside of the diaphragm 53; should the liquid pressure rise to a value greater than that exerted by the spring 57 then the diaphragm 53 is forced upwardly and the valve 38 is seated until the pressure in the outlet chamber 45 falls to or below the setting of the spring 57 whereupon the member 38 is again moved away from its seat. The loading of springs 26, 42 and 57 is adjustable.
