Title: Process for the manufacture of monoferro-dicalcium-citrate
Filed: 1951-11-21
Abstract: The invention comprises the new compound mono-ferro-dicalcium citrate of formula Ca2Fe(C6H5O7)2. It may be prepared by reacting citric acid in aqueous solution with ferrum reductum or a ferrous compound and a calcium salt in stoichiometrical proportions or with an excess of the calcium salt, the water being expelled after the reaction is completed until the completely anhydrous citrate remains.  Preferably a protective gas, for example hydrogen, nitrogen or carbon dioxide, is passed through the reaction mixture until all the water had been removed.  In the examples (a) citric acid is reacted with ferrum reductum to form an acid ferro citrate which is reacted with calcium carbonate to give mono-ferrodicalcium citrate; (b) citric acid is reacted with ferrous hydroxide to give an acid ferro citrate which is reacted with calcium carbonate to give mono-ferro-dicalcium citrate.

Abstract: 724,288. Treating charge ; preventing backignition. LANG, A. Nov. 3, 1952, [Nov. 6, 1951], No. 27587/52. Class 7 (2). A valve 46 Fig. 3, controls the transmission under engine suction of petrol vapours and crankcase fumes from diametrically opposed copper or other pipes 45 to the engine intake pipe 70 via an angularly adjustable nozzle 51 projecting thereinto and held in adjusted position, facing downstream, by a spring 55. The member 48 enters the intake pipe up to the shoulder 49 which is welded thereto, and leakage between the members 40, 48 is prevented by a preferably heat-resistant, e.g. copper or asbestos, washer 65 when a nut 63 is screwed up. That pipe 45 feeding petrol vapours communicates with the fuel tank filler tube via means comprising a connector 25, Fig. 1, to which the pipe is welded, a spring-loaded ball valve 18, a control valve 15 and a member 6 which passes through the curved surface of the filler tube (not shown), is clamped thereto by a nut 58 and yielding washers 56, 57, and communicates with the interior thereof via a filter 8. The ball valve 18 opens under engine suction but closes to seal off the fuel tank when the engine is inoperative or back-ignition occurs. That pipe 45 feeding crankcase fumes communicates with a valve cover or rocker casing or the crankcase oil filler pipe via similar means (Fig. 2, not shown) to that described above but without a ball valve and with the filter 8 replaced by a suction head having a plurality of radial inlets.

Title: Improvements in and relating to electron-emission microscopes
IPC: H01J37/285
Filed: 1962-07-19
Abstract: 966,442. Heavy-ion-beam tubes. TRUB, TAUBER & CO. A.G. July 19, 1962 [Nov. 9, 1961], No. 27750/62. Heading H1D. In an electron microscope for forming an electron-optical image of a surface, the surface is bombarded by both a beam of ions and a beam of electrons, either simultaneously or alternately. The tube T contains an ion source Ai and one or more electron sources Ke, all of which bombard the specimen O. The specimen O emits secondary electrons which are accelerated and focused by the control electrode S, anode A, diaphragm FB and lens Pr on to a luminous screen L or photographic plate P. The emission from the specimen may be induced either by the ion bombardment, with a soft electron beam, or by a hard electron beam together with the ion beam. Such simultaneous bombardment reduces space charge distortions and contamination of the specimen surface. Since the two beams curve differently as they approach the specimen, they may be made to strike the target in identical directions. The specimen may be heated by the resistance windings OH, or by electron bombardment from behind. The specimen may be moved laterally, or rotated. The specimen may also be irradiated by ultraviolet light, e.g. from a laser, and the tube may also contain a metal vapour source, to coat the specimen surface.

Abstract: 601,044. Electromagnets. MIDHAT, S. Oct. 22, 1945, No. 27774. Convention date, Feb. 6, 1941. [Class 35] [Also in Group XXXVI] The core of a solenoid is formed of at least one part of magnetized steel and one part of soft iron. In the ammeter or voltmeter shown in Fig. 3, a toroidal core is formed of a segment 1a of magnetized steel, a segment 1b of soft iron and a segment 1c of non-magnetic metal. The complete core is mounted by means of arms 13 on a freely rotatable spindle 2 carrying a pointer 7 and is rotatable within a toroidal solenoid 3. When a weak current flows in the solenoid 3, the magnetized steel segment 1a takes up a position in the centre of the solenoid, the soft iron segment 1b being only slightly magnetized. With stronger currents the segment 1b becomes more strongly magnetized and moves towards the centre of the solenoid.

Title: Improvements relating to compositions for the production of cores for use in metal casting
Inventor: RAYNER CLAUDE ALBERT ABBS
IPC: B22C1/22
Filed: 1951-11-28
Abstract: In the production of sand cores for metal casting the core binder is applied to the sand in the form of an emulsion of the water-in-oil type comprising a solution or dispersion of a thermosetting resin in a hydrophobic medium, e.g. hydrocarbon oil. A cereal binder, e.g. starch, may also be added.  Phenol-, urea-, melamine-formaldehyde resins reacted to the water soluble stage, e.g. soluble in dilute alkali, or dissolved in alcohol-water or acetone-water mixtures, or methylol compounds, which, on baking the sand composition, decompose to give resins may be employed. In the latter case small crystals of the methylol compounds are present in the emulsion.  Hydrocarbon oils boiling between 120 DEG  and 360 DEG C. are employed as the continuous phase.  In examples (1) 150 pts. of a 45 per cent. aqueous colloidal solution of a urea-formaldehyde resin are added to a mixture comprising 30 pts. kerosene, 4 pts. "Belloid F.R." (a fatty acid ester of an alkanolamine), 0.2 pts. "Nervan C.S." (a mixture of sulphated olefine and sulphated ester), 150 pts. water and the mixture stirred until a homogeneous emulsion is formed.  (2) 190 pts. 37 per cent. formaldehyde and 100 pts. urea are heated to 90 DEG C. and then cooled to 50 DEG C.  The methylol urea obtained is emulsified in a mixture of Belloid, calcium oleate, kerosene and water.  (3) As in (2) with the addition of 50 pts. starch.  (4) A phenolformaldehyde resin is emulsified in kerosene, with the aid of a heavy metallic soap of wood grease and calcium oleate.
