Title: Sulphur dioxide producing process
Inventor: HANSFORD KENNETH RALPH
IPC: C01B17/50
Filed: 1961-04-17
Abstract: Sulphur dioxide is produced by forming an aqueous FeSO4.H2O suspension by the process of any of the claims or Specifications 800,410 or 834,624 and roasting a mixture of the aqueous FeSO4.H2O suspension, a fuel and an oxygenating gas at a temperature above that at which the reactants commerce to form SO2. The process may be carried out in a fluidized bed fluidized by the oxygenating gas and/or other gas and the FeSO4.H2O suspension injected as a spray. The fuel may be: coke or coal, carbon, CO, oil, sulphur or iron pyrites. The oxygenating gas may be oxygen or air. The gases produced may be used in the manufacture of H2SO4 by first cooling to 350 DEG C., removing suspended solids in a cyclone, followed by evaporative cooling to 70 DEG  C., and further cooling by water in countercurrent to 35 DEG  C.  The cooled gases are mixed with a stripping gas which has been used to remove SO2 from the cooling water, and further air admitted and the gases converted to H2SO4 by a conventional procedure.  In Example (1) a bed of fluidized ferric oxide particles of size 100-400 microns was heated to 825 DEG  C. by oil and preheated air (300 DEG  C.)  The oil feed was stopped and an aqueous slurry containing 40% of iron pyrites and 26% made by the process of Specification 800,410 was injected.

Title: Improvements in or relating to machines for testing the thickness of sheet materials
IPC: G01B5/06
Filed: 1932-05-17
Abstract: 403,624. Linear - dimension gauges. CHIVERS & SONS, Ltd., Histon, Cambridgeshire, and FISON, F. J., 70, Holbroke Road, Hills Road, Cambridge. May 17, 1932, No. 14067. [Class 106 (ii).] Comprises a particular construction of machine for testing the thickness of sheet material in which a lever operated pressure member or members in the form of vertically moving spring pressed plungers engage the material which is supported on a table, and a lever amplifying indicating mechanism is provided. The table 6 is mounted on a portable structure 7 and spring pressed plungers 8, 9 are movable in guides 12 in a frame 13 extending over the table. Movement of the plungers is transmitted to sliding rods 23, 24 which actuate indicating mechanism. The rod 23 engages a pivoted spring lever 25 near its fulcrum, the end of the lever engaging a second pivoted lever 27 carrying at the end a contact 29 adapted to engage a fixed contact 30 in the circuit of a lamp 31. Similar mechanism is provided in connection with the sliding rod 24 to co-operate with a lamp 32. The plungers are normally kept raised by a heavy spring 16 acting on a pedal 17 which pulls down a rod 18 and levers 19, the bifurcated ends 21 of which engage collars 22 on the plungers. In use, the sheet is placed on the table on anvils 10, 11 and the pedal 17 operated to lower the plungers. If the material is too thin the lamps light up. In a modification, Fig. 4, only one plunger 35 is provided having a rocking foot 36 provided with several contact points for the sheet. The arrangement may be that the plungers normally bear on the table but are raised to insert the sheet. The lamps may be arranged to indicate when material is too thick or when the material is between set limits of thickness.

Title: Improvements in and relating to electronic controlling or regulating systems
IPC: G05B11/01
Filed: 1948-05-25
Abstract: 681.703. Electric indicating, control systems. COOKE, E. J. June 24, 1949 [May 25, 1948], No. 14124/48. Class 40 (i) [Also in Groups XXXV, XXXVI and XL(c)] In an electric indicating or control system responsive to a variable quantity, a H. F. Colpitts oscillator (Fig. 2) comprises a triode V1, having anode feed resistance R2, grid condenser Cl and grid resistance RI combined with a grid-anode tuned circuit in which inductance L1 is paralleled by the grid-anode valve capacity CAG, and by the anode-cathode capacity CAK in series with the grid-cathode capacity CGK paralleled by a small capacity CV controlled by the variable; e.g. by the pointer of the millivoltmeter of an electric furnace pyrometer. The cathode is returned to the junction of CAK and CGK which may be tapped to the inductance, and the value of CV determines the feedback and the oscillation amplitude without substantial frequency changes, thus controlling the anode current and potential of VI. In Fig. 3, V1 is coupled through resistance R3 to the grid of triode V2, which comprises a trigger circuit with triode V3, whose anode circuit contains a relay A controlling e.g. the electric furnace supply. Initially the trigger circuit is stable with V2 conducting, V3 cut off, and the relay inoperative. Falling furnace temperature varies capacity CV to increase the anode current of V1 and lower the grid potential of V2. The trigger circuit changes over to V2 cut off and V3 conducting, to operate the control relay and reconnect the furnace supply. Variation of CV in the opposite direction with rising temperature decreases the anode current of V1 and changes the trigger circuit over to the original condition with the relay inoperative. The threshold may be adjusted by the biasing potentiometer R5 and the vanes of CV may be mounted respectively on the pointer of the pyrometer instrument and a concentric preset temperature control arm. Additional trigger units may be connected for control by V1. In a modification Fig. 4 (not shown) the capacity CV has two fixed plates and one moving plate operated by the indicating galvanometer of a bridge or potentiometer circuit and controls two oscillators and trigger circuits operating a relay controlled motor to adjust the potentiometer or bridge sliderwire tap for rebalance.

Title: Chlorination of propyne

IPC: C07C17/10
Filed: 1960-04-25
Abstract: Propargyl chloride, monochloroallene and a mixture of cis- and trans-1,2,3-trichloropropene are obtained by heating propyne in the gaseous phase with chlorine at elevated temperatures not exceeding 800 DEG C., preferably between 500-600 DEG C.  The reaction is preferably carried out in the presence of an inert gaseous diluent such as nitrogen, and the preferred contact time of the reaction mixture is substantially 0.01 to 1 second.  The chlorination products may be separated by fractional distillation.  In an example the reactants, containing nitrogen as diluent, are fed through a quartz tube, heated to 520-570 DEG C., with a contact time of 0.2 seconds. The products are then freed from chlorine, nitrogen and propyne, and submitted to fractional distillation.  In the Provisional Specification no temperature limits are mentioned for the chlorination process.

Glue, with or without a hardening agent, is applied to the grooves 21 of the walls 1, 2, and/or the edges of walls 3, 4, and the walls are fed from the left, being guided by rollers 6a, 6b, and 13, 15 respectively. Walls 3, 4 are then positioned by rollers 14, 16 and walls 1, 2 thereafter guided towards walls 3, 4 by rollers 7 so that the edges of walls 3, 4 are received in the grooves 21. Walls 1, 2 are maintained at the correct distance apart by rollers 8. The girder is then guided by rollers 9 and 12 while the glue sets, and is cut into lengths at E-E. The apparatus may be surrounded by a heat insulating casing and the joints of the girder may be heated within the apparatus or the joint surfaces may be heated before they are brought together. The joining may be effected by screwing, nailing, etc. Heat and/or sound insulating material may be introduced into the hollow of the girder while the walls are being brought together. The guiding members may consist of slide bars.
