Title: Improvements in and relating to the purification of sulphuric acid
IPC: C01B17/90
Filed: 1934-04-12
Abstract: <PICT:0441452/III/1> Organic matter is removed from crude sulphuric acid, e.g. spent nitration acids, by heating the acid to a temperature of above 100 DEG  C., introducing nitric acid, and maintaining the mixture at an elevated temperature to oxidize the organic matter. Nitroglycerine spent acid is diluted with dilute nitric acid and this mixture is supplied to the top of a dehydrating tower B.  The partially concentrated acid flows through an outlet C into a series of externally heated boiling vessels D1, D2, D3 and D4 where temperatures of above 150 DEG  C. are maintained.  The vapours boiled off go to the dehydrating tower through fume outlets such as F1.  Concentrated nitric acid is condensed from vapours passing from the tower B by means of a condenser L and a portion thereof is fed through a valve N into the sulphuric acid in the vessel D3. The concentrated sulphuric acid flows to a vessel G where it is denitrated by means of steam.  The statement of prior act refers to the bleaching of dark coloured sulphuric acid containing organic matter by means of sodium chlorate or hydrogen peroxide.

Abstract: 1,151,157. Automatic steering control. HUDSWELL YATES DEVELOPMENTS Ltd. March 6, 1968 [March 10, 1967], No. 11289/67. Heading G3R. [Also in Division A1] Mole plough apparatus consists of a mole plough blade 27 attached to a tracked vehicle 8 which moves forward by means of cables 20 attached to a ground anchor 21 and two laterally spacedwinches 18 mounted on the vehicle and means for controlling the relative effective length of the cables whereby to control the attitude of the vehicle and hence that of the blade 27 about an axis perpendicular to the ground. The winches 18 are driven by hydraulic motors 23, 24 controlled by pumps 28, 30 via links 40, 42 and levers 36, 38. Automatic steering is provided by the inclusion of ram assembly 44 between portions 42a, 42b of link 42. A deviation from the desired path is detected by the automatic steering gear (not shown) and results in pulse energization of line 76 or 78. This causes the solenoid operated valve 68 to feed hydraulic fluid through pipe 64 or 66 temporarily displacing the ram either to the right or to the left and thus shortening or lengthening link 40. This will produce the desired correction in the steering and the ram returns to its original position under the action of springs 58. To connect the automatic steering, levers 36, 38 are latched together thus operating electric switch (88) which holds valve 68 in the "off" position until the switch is operated, see Fig. 6 (not shown), for general speed change, levers 36, 38 can be operated together. The relative length of the cables can be altered in other ways for example by moving one of the winches in a longitudinal direction or moving a pulley or another member into contact with the cables.

Abstract: 697,130. Electric signalling systems. VOLTRAM, A. B. May 18, 1951 [May 19, 1950], No. 11705/51. Class 40 (i) [Also in Group XL(c)] Alarm apparatus responsive to the international S.O.S. pre-signal, i.e., 12 dashes, each of 4 seconds duration, separated by one second intervals, comprises a heated-cathode rectifier Va so connected that the filament circuit is broken upon receipt of each dash, the filament cooling sufficiently on receipt of the pre-signal, or a continuous signal of the same length, to de-energize a relay in its anode circuit to operate an alarm. Valves Va, Vb are normally conducting, relays Rc, Rd are energized and lamp Sa alight. Incoming signals applied at I1, I2 actuate a sensitive relay Ra which responds to dots or dashes and energizes a relay Rb. The latter is of the delayed action type and pulls up only upon the receipt of signals of the duration of dashes or of a continuous signal. The relay Rb thus responds to the pre-signal and opens the filament circuit in step (with a slight delay) with the received signal dashes. The filament under such circumstances is cooled sufficiently before the end of the S.O.S. pre-signal to release the relay Rc to extinguish lamp Sa, light Sb and actuate the alarm G.

Abstract: 1,211,850. Extruding clay. SERVICE (ENGS.) Ltd. 12 March, 1968 [14 March, 1967], No. 11786/67. Heading B5A. In a machine for extruding clay, a chamber 24 is provided which is connected via a line 50 to a vacuum pump and via a line 52 to a source of steam, the arrangement being such that during working and extrusion of the clay by screw 14, i.e. until the extrudate contacts a microswitch 36, 38 to stop the screw drive, steam is delivered to chamber 24. The machine works intermittently, since on triggering of microwswitch 36, 38 the extrudate is cut-off by a knife 40, the switch thereby being released and the screw drive again becoming operational. The steam is generated in a boiler 54 which contains an electrically heated column 56 provided with a spiral fin 58. Cold water is admitted to boiler 54 via a pump 68, connected to a shaft 32 of the screw drive, and a control valve 62, regulated by a thermocouple 64 which detects the temperature of the extruding clay. In operation, a small quantity of water is pumped into boiler 54 when screw 14 is driven, which water is immediately converted into superheated steam, e.g. steam at 130 C., and enters chamber 24 under its own pressure. In a modification, thermocouple 64 may be connected to the heaters in column 56 instead of to valve 62. As shown, clay pieces C are delivered to moulds M of a cup-making plant.

Patent GB-456973-A (GB)
Title: Improvements in or relating to the manufacture of bottle caps from cellulose esters
IPC: B29D99/00
Filed: 1935-04-18
Abstract: Shrinkable cellulose ester bottle caps are obtained by dissolving a fully esterified cellulose ester in an organic compound that is a non-solvent at ordinary temperature but acts as a solvent on heating, forming the cap by solidification of a layer of the solution on a former, and removing the bulk of the organic compound.  Diacetone alcohol, benzyl alcohol, furfuryl alcohol, tetrahydrofurfurylalcohol, ethyllactate, glycerol mono-acetate, benzyl acetate, methyl ether of ethylene glycol, methyl or ethyl salicylate, and butyrolactone are specified liquids which may be used as solvents on heating. Plasticizers, fillers, and colouring matters may be added to the solutions.  The former may be a test-tube or similar tube closed at one end. Cooling of the layer of solution on the former may be effected by cooling the former internally and immersing it with the adherent film in a cold bath such as cold water, or water and ethyl alcohol or other organic liquid miscible with the organic compound employed as solvent.  If desired, the solidification may be carried out in one bath, and removal of the organic compound in a second bath.  In examples, cellulose triacetate, including esters having acetic acid content above 60 per cent, is dissolved in hot tetrahydrofurfuryl alcohol with or without amyl stearate, or in diacetone alcohol and tricresyl phosphate, or ethyl lactate and tributyl citrate, or ethyl lactate and dilauryl phthalate, together if desired with pigments such as titanium dioxide, aluminium powder, or dyestuffs.  Caps are produced by dipping cold formers such as water-cooled test-tubes, into the solution or successively into two different solutions, and then immersing in water, aqueous alcohol or aqueous diacetin.  The caps are removed from the formers and preserved in water or in wet or damp p  condition until ready for use.  They are applied wet and shrink on to the corks or stoppers as they dry.  In another example, a fully esterified mixed cellulose ester containing acetyl, crotonyl, and butyryl radicles is employed. It is dissolved in hot tetrahydrofurfuryl alcohol and butyl oleate, and to the solution, talc and chrome yellow are added.  The solution is formed into caps.
