Title: Process for the purification of impure sulphur
IPC: C01B17/02
Filed: 1931-08-18
Abstract: A solution of sulphur in carbon bisulphide obtained by the extraction of sulphur bearing materials, such as spent oxide, is freed from contaminating tarry or other organic matter by continuous passage with fuming sulphuric acid through an agitator, after which the mixture is passed to a separator, the sulphur solution being drawn off at the top and the fuming sulphuric acid at the base.  The pure sulphur solution may be neutralized by passage through a bed of chalk &c. and the tarry acid may be used to dehydrate untreated sulphur solution.  Preferably, acid containing 20-30 per cent of free sulphur trioxide is employed and to reduce the amount used, a preliminary purification as described in Specification 386,969 may be effected. According to the Provisional Specification, the process need not be continuous.

Abstract: 804,636. Making heat-exchangers. SERCK RADIATORS, Ltd. July 11, 1957 [July 27, 1956], No. 23245/56. Class 83 (2). [Also in Group XIII] A method of making a tubular element for a heat-exchanger of the kind formed from two thin metal sheets a which are welded together at a number of predetermined positions by a pair of rolls, and which are subsequently dilated by fluid-pressure at intermediate positions, is characterized in that the welding action of the rollers is restricted to the parts b of the sheets to be united and effects the desired thinning of the sheets at those parts to produce an element of uniform thickness. Coating of the sheets in the parts required for forming the tubes with non- weld material is thus avoided.

Title: Improvements relating to Automatic Testing Systems
Inventor: DUNCAN DAVID ANTHONY DILWYN
IPC: G05B19/14
Filed: 1965-06-01
Abstract: 1,159,431. Programmed control of testing. BRITISH AIRCRAFT CORP. Ltd. Aug. 31, 1966 [June 1, 1965], No.23333/65. Heading G3N. A programming means includes a series of parts for successively controlling an automatic sequential testing system to carry out tests on an object, a response to a test being evaluated in dependence on tolerance values to determine the code of a further part, not the next in the series of parts, in the event of a predetermined response to a test. As shown, a punched tape 10 is coded with a succession of sets of test instructions, each set of which includes instructions determining the nature of a test and an indication of the next set of instructions to be carried out as a result of the test. The set of instructions is read by a tape-reader 11, the output of which, for a prime test, determines through a central control system 13 the application of a test signal to a part of an object 18 selected through a switching circuit 16. The response of the object to the test signal is determined, through a switching circuit 19, by a measurement and assessment circuit 21 the tolerance values for which are determined by the central control system. The result of the test is fed to the central control system which initiates the recording of the result by a line printer and tape punch 23. The state of the test system, and the existence of a fault, is indicated on a display panel 25. When the test tolerances have been met the central control system initiates the movement of the tape by a reversing drive 12 in a search for the next prime test. When the test tolerances have not been met, the tape is stepped to a self-check set of instructions. If the self-check is satisfactory, diagnostic subroutines are sequentially read and applied to the test object to locate the fault.

Abstract: 388,073. Concrete aggregates. GREENAWALT, J. E., 135, East 42nd Street, New York, U.S.A. Aug. 19, 1931, No. 23364. [Class 22.] A porous aggregate for concrete is produced from household refuse by sifting the refuse to remove the fine dust, the remainder being separated into two or more components according to the size of the particles, charged in superposed layers on a grate 26 and burnt, the resulting clinker being mixed with the fine dust and sintered. A grab 1 hoists the garbage from a pit P to a feed hopper 4 above the vibrating screen which comprises two superposed screen elements 7, 8. Fine ash &c. passes through both screens into a hopper 19, while the material which passes through the upper screen 7 falls on to a belt 15 and the coarser material on to a belt 10, the belts delivering to separate compartments 22, 23 of the hopper feeding the furnace 25. The belt pulleys are magnetic to remove metal particles, and articles such as bottles &c. are removed by hand from the belt 10. At the discharge end of the grate the clinker is cooled by water jets, crushed and mixed with the fine ash &c., separated by the screen 8, which is conveyed to the discharge point by a belt 47. The mixture is then screened and sintered to produce the porous aggregate. The furnace atmosphere and the speed of the grate may be controlled so as to obtain a clinker having a predetermined carbon content suitable for the sintering operation. Specifications 373,084, and 388,074, [Group XII], are referred to.
