Patent GB-484037-A (GB)
Title: Method of producing dicalcium phosphate and calcium nitrate solution
IPC: C05B11/06
Filed: 1937-05-25
Abstract: In the production of dicalcium phosphate and calcium nitrate solution by dissolving phosphate rock in nitric acid and neutralizing the solution by lime or limestone, the addition of the neutralizing agent is regulated so that the dissolved iron and aluminium are to an essential part precipitated from the solution before precipitation of the dicalcium phosphate occurs, this latter being effected by continued addition of the neutralizing agent.  Easily filterable crystals of dicalcium phosphate are thereby obtained.  Unless a pure product is required, the iron and aluminium precipitate need not be removed prior to the precipitation of the dicalcium phosphate.  The solution to be neutralized should have a free P205 content not exceeding 8 grms. per 100 cc., and preferably below 7 grms. per 100 cc. solution, the concentration being adjusted by adding calcium nitrate solution and/or water at or after the dissolving of the rock. The first stage of the neutralization should be effected by supplying the acid solution and lime or limestone simultaneously to a reaction vessel.  After the first stage, the free P2O5 content should be at least 1 grm. per 100 cc.  Small portions of lime or limestone are then supplied to batches of the partly neutralized solution until the remaining impurities are precipitated, whereupon the addition of the neutralizing agent may be accelerated to precipitate dicalcium phosphate.  The ratio of H2SiF6 to Al2O3 should be from 2 : 1 to 3 : 1.  If the ratio is too low, a fluor compound is added on or after dissolving the rock; if too high, a complex salt containing aluminium and fluorine is precipitated from the solution according to the method disclosed in Specification 467,843.  Reaction is conveniently effected at 30-35 DEG  C., a temperature up to 40 DEG  C. being however permissible at the beginning.  The limestone used is preferably mixed with calcium nitrate solution.  The last precipitation may be made with lime or ammonia if the limestone is not sufficiently finely ground.  Four examples are given, one demonstrating that small needle-shaped badly-separating crystals of dicalcium phosphate are obtained when the first neutralizing stage is carried so far that the solution then contains less than 1 grm. free P2O5 per 100 cc. solution.

Abstract: 1505223 Cathode replacement in shortcircuited cells OUTOKUMPU OY 9 April 1976 [10 April 1975] 14580/76 Heading C7B In an electrolytic cell having alternate cathodes and anodes e.g. for Cu electrowinning, individual cathode currents are measured via a parameter dependent thereon and any cathode showing excess current is removed and replaced by means of a device movable along the tank. The current may be measured by magnetic field or voltage drop in the cathode bar, or by thermal detection e.g. I-R photography. As described, a device on rails above a set of tanks has a row of gaussmeters (one per cathode) which are reciprocated in turn adjacent each set of cathode bars. A fault signal actuates a conveyer device which collects a new cathode from a store and removes the faulty cathode to a second store. The anode contact voltage losses may be simultaneously measured for warning of necessary contact cleaning.

Title: Improvements in synthetic resins and process of making the same
IPC: C08G16/00
Filed: 1924-06-17
Abstract: Synthetic resins in three stages of condensation, fusible and soluble, fusible and insoluble, and infusible and insoluble, are obtained by condensing together a ketone, a coal tar oil boiling above 224 DEG  C., and formaldehyde, paraformaldehyde, hexamethylenetetramine, or furfural.  Alkaline or acid condensing agents may be employed, but alkaline hydroxides or carbonates are preferred.  The resins may be used for varnishes, electric insulation, for translucent articles such as tobacco pipe mouthpieces, or may be mixed with fillers such as sawdust or asbestos at any intermediate stage of the condensation.  Light or heavy acetone oils may be employed as the ketonic body.  An example shows the condensation of coal tar oils boiling between 224 DEG  C. and 300 DEG  C. with acetone and paraformaldehyde in presence of caustic alkali.

Title: Improvements in multi jet carburettors for variable speed internal combustion engines
IPC: F02M3/045
Filed: 1945-06-12
Abstract: 593,288. Spray carburetters. ELLIS, R. G. June 12, 1945, No. 1'4851. [Class 7. (iii)] In a carburetter wherein an automatic device prevents fuel issuing from the pilot jet during over-running, a manually operated control is added to suspend operation of the device during manoeuvring of the vehicle and also to economise fuel when running under light loads by cutting off the pilot jet. In Fig. 1 a tappet 14 is actuated against a spring 22 by a solenoid 17 connected to an engine-driven dynamo 5 to close the pilot jet 8. The manual control comprises a master switch 24 with contacts 25, 26, 27. When set at 26, release of the accelerator pedal 3 closes the contacts 29, 30 to complete the circuit and the jet 8 is closed if the engine speed is sufficiently high; when at 27 the circuit is aways completed and the jet 8 permanently cut out to economise fuel; and when at 25 for manoeuvring the circuit is broken and the jet 8 remains open. The solenoid 17 may be separate from the carburetter and operate the tappet 14 through a Bowden wire. Instead of closing the jet 8, the tappet may close the idling passage 11, or it may be replaced by a piston which uncovers ports-at over-running and admits excess air to destroy the suction in or near the idling passage. In a modification a Bowden wire operating any of the above devices is connected to a centrifugal govenor driven by the ignitionhead shaft. The manual control used with this modification comprises a knob 77, Fig. 12, controlling through levers 76, 74 and a pulley 72 round which passes a bight of the Bowden wire 41 from which the casing has been removed. With the knob 77 in the middle position shown and with the accelerator pedal pressed, the wire 41 is slack and the over-running device is inoperative, but on releasing the pedal the lug 80 on the rod 4 contacts the end of lever 74 and moves the pulley 72 backwards, tightening the wire 41 and allowing the over-running device to operate. For economy at high speeds the knob 77 is pushed in which raises the lever 74 to clear the lug 80 and maintains the wire 41 tight at all throttle openings. During manoeuvring the knob 77 is pulled right out, again raising the lever 74 to clear lug 80 but maintaining the wire 41 slack at all throttle openings so that the idling jet is left in operation. The idling passage may have a two-hole outlet-52, Fig. 15, excess air being admitted to a hole 83 to destroy the suction by a solenoid operated piston uncovering the ports 80, 82. The single hole 83 may be replaced by three holes 84, 85;.86, Fig. 20. Two modified forms of the electrical circuit are shown which expedite the release of the armature of the solenoidoperated devices.

Filed: 1946-05-17
Abstract: 630,429. Hot-gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 17, 1946, No. 14979. Convention date, Nov. 12, 1941. Drawings to Specification. [Class 7 (i)] In a hot gas engine in which a heat-conveying medium is provided between the source of heat for the' engine and the heater which heat-conveying medium receives through a wall heat from the source and delivers the heat through a wall of the heater to the working medium in the engine the temperature in the hot space exceeds 400‹ C. in operation of the engine the heat is conveyed from the source of heat to the heater by the circulation of the heat-conveying medium which is continually in the liquid phase during operation of the engine and the heat-conveying medium is constituted by a liquid metal or a liquid metal alloy. The medium consists of a metal or metal alloy which is liquid at the operating temperature and is referred to as a liquid metal or liquid metal alloy. The liquid metal may be sodium or potassium and the liquid metal alloy may be an alloy of these metals or Woods' metal. A burner heats the heat-conveying medium in a chamber and it is then circulated through a conduit to a jacket around the engine heater in which it gives up heat to the working medium in the engine. The medium then flows under the action of a pump back to the chamber where it is reheated by the burner. Although the heatconveying medium may be brought into circulation due to the heating effect of the burner it is preferable that it should be brought into circulation or held in circulation by artificial means. By the introduction of a gas or vapour e.g. argon gas into the heatconveying medium at a suitable point gas or vapour bubble lift may be obtained. Where a pump is used to circulate the medium it may be a centrifugal or diaphragm pump and may be driven from the outside for example by means of an electromagnetic coupling. It is possible to act on the heat-conveying medium by a magnetic field passing through the liquid. This may be done by use of a rotating magnet. It is stated that the medium may be subdivided at the source of heat or the heater into a number of parallel channels. The Specification as open to inspection under Sect. 91 comprises also arrangements in which a gas for example, sulphofluoride or salts for example zinc chloride or cadmium iodide are employed for the heat-conveying medium. This subject-matter does not appear in the Specification as accepted.
