Title: Improvements in or relating to the low temperature reduction of oxidic iron ores
IPC: C21B13/00
Filed: 1955-10-12
Abstract: 792,926. Reducing iron oxides. HAKEN,K. VON, and HAHN, J. B. Oct, 12. 1955 [Oct. 13, 1954; June 10, 1955], No. 29111/55. Class 72 A process for the production of pure iron from brown magnetic iron oxide comprises intimately mixing the finely divided oxide with a carbonaceous reducing agent while both oxide and reducing agent are maintained in suspension in a current of carbon monoxide containing reducing gas at 350-540‹C. As shown, fine magnetic iron oxide is injected by a reducing gas from a hopper 15 through nozzles 14, situated above the lowest layer of a series of dust separators 13, on to the topmost layer of a series of channels 16. Carbon dust from hoppers 22 is injected into pipes 24, through valves 20 which are opened intermittently by means of a chain gear 21, lying in the channels 16. The ore and reducing agent fall on to the lower channels and finally, after falling from the lowermost channel, pass through a zone heated to 700‹C. and into which are injected soda and lime dust from a hopper 31, to form a thin skin of clinker and gangue on the iron particles. The material passes through a cooler 25 to reduce the temperature to 100‹C. and is removed from the furnace through a pipe 26. The iron oxide may be pelleted with reducing agent and iron compounds other than brown magnetic oxide may be added in amount double that of the magnetic oxide; in the latter case the product from the furnace is subjected to further reduction without cooling at a temperature up to 640‹C.

Patent GB-789566-A (GB)
Title: Polyol alcoholates
IPC: C22B3/26
Filed: 1955-10-14
Abstract: The invention comprises the polyol alcoholate reaction product of a water- or acid-soluble compound of a metal of Group IVa of the Periodic Table, including cerium, with a polyhydroxy organic compound containing at least four carbon atoms and at least four hydroxyl groups per molecule, in proportions to provide more than one hydroxyl group for each valence charge of metal.  The preferred polyhydroxy alcohols are hexitols derived from various monosaccharides, e.g. sorbitol, mannitol and dulcitol, monosaccharides such as glucose and mannose, other aliphatic polyols such as 1,2,3,4-butanetetrol, arakitol and pentaerythritol, and alicyclic polyols such as inositol. The polyol alcoholates may be prepared by various methods.  For example, polyol titanates may be prepared by mixing an aqueous solution of the polyhydroxy alcohol with a slurry of titanium orthohydrate produced by the hydrolysis of a water-soluble titanium salt such as titanyl sulphate or titanyl chloride.  An alkalizing agent, such as ammonia, may be necessary in the reaction mixture. Alternatively they may be prepared by adding the polyol to an orthotitanic ester of a simple alcohol, e.g. isopropyl titanate, if desired, in the presence of an alkalizing agent.  In the examples, (a) a solution of isopropyl titanate in tetrahydrofuran is added to a solution of sorbitol hemihydrate in methanol to give sorbitol titanate; (b) titanium chloride solution is mixed with mannitol solution at boiling-point; sodium hydroxide is added and a solution of mannitol titanate is obtained; (c) an aqueous solution of adonitol is added to titanium sulphate solution to give adonitol titanate; (d) isopropyl titanate is heated with sorbitol to give a partially polymerized sorbitol titanate; (e) a slurry of titanium orthohydrate is added to a solution of sorbitol hemihydrate and sodium hydroxide is added; sorbitol titanate is obtained; (f) a mixture of zirconium and hafnium tetrachloride in water is added to an aqueous solution of sorbitol hemihydrate; a solution of mixed sorbitol zirconate-hafnate is obtained; (g) titanium chloride solution is mixed with dulcitol solution to give dulcitol titanate; (h) titanium chloride solution is mixed with inositol solution to give inositol titanate; (j) titanium chloride solution is mixed with pentaerythritol to give pentaerythritol titanate; and (k) ceric sulphate solution is mixed with mannitol solution to give mannitol cerate.  Specifications 755,728 and 759,570, [Group IV (c)], are referred to.ALSO:Equimolecular proportions of isobutyl titanate and sorbitol are heated together to give a partially polymerized sorbitol titanate which is slowly soluble in water but readily soluble in aqueous ammonia or gluconic acid solutions.

Title: Testing logic circuits
IPC: G11C29/56
Filed: 1972-06-23
Abstract: 1340157 Testing logic circuits INTERNATIONAL BUSINESS MACHINES CORP 23 June 1972 [2 Aug 1971] 29418/72 Heading G1U A logic circuit is tested by applying a sequence of parallel words to its input, accumulating its parallel output words and comparing the resulting sum with a number produced by performing the same test on a standard or simulated reference circuit. As described the sequence of test words may be generated using a pseudo-random number generator as described in Specification 1291522 and outputs from the circuit under test that are subject to 'race' conditions may be detected as described in Specification 1294280 and omitted from the subsequent accumulation. A block diagram is described in which a sequence of test words is applied by a generator 40, Fig.4, to a circuit 41 which may be either the reference circuit 41A or the circuit to be tested 41B, and the resulting output words are entered via gates 45 into a parallel accumulator 44, the gates 45 being controlled by the contents of a store 43 sequentially read by a counter 42, in such a way that for each test word those outputs that are known to be subject to race conditions - these being identified beforehand by the method described in Specification 1294280, are inhibited. An arrangement is also described Fig. 5 (not shown) whereby when the logic circuit under test has only a few outputs, these may be 'proliferated' on to a larger number of leads by means of shift registers, thereby according to the Specification, reducing the risk of mutual cancellation of errors.

Filed: 1933-10-24
Abstract: 427,421. Cooling cylinders. ILLSLEY, F. P., Lake Harbor Road, Muskegon, Michigan, U.S.A. Oct. 24, 1933, No. 29452. Convention date, Oct. 24, 1932. [Class 7 (ii)] [See also Group XXIX] A closed cooling system in which circulation of the cooling liquid takes place at superatmospheric pressure includes a pressure-release valve 15, the operating member of which has a pressure area substantially greater than that of the release port. The valve may be attached to, or formed by pressing down the edge of, a port in a corrugated brass, or bronze, diaphragm 13 constituting the operating member. The cooling liquid is circulated through the radiator r by a pump p ; a non-return valve g and a valve v, closed by a thermal element u, cut off the radiator at starting, and ensure quick warming up. The top tank t of the radiator constitutes a large vapour space, the level of liquid therein being regulated by a float valve 33, which is held closed, until the cooling liquid is hot, by a bimetallic strip 39 ; the level is made up from a tank 25, vented to the system by a pipe 42. Alternatively a simple filler cap may be arranged at the desired level in the tank t. A ball-valve 3, or a valve controlled by a bimetallic strip and arranged at the side of the valve 15, allows air to enter the system when the liquid cools on stoppage of the engine. In an alternative arrangement the ball-valve 3 is replaced by a spring-pressed plug-valve arranged at the axis of the base of the casing of the valve 15, which is detachably mounted in the top of the tank t. The filler-cap of the tank may be held by pins working in bayonet slots having stops which resist opening movement when considerable pressure exists in the tank. A flexible diaphragm 22 enables the pressure in the tank t to be used for operating accessories, e.g. radiator shutters, which are connected to an attachment 24.

Multiple sheet glazing units are made by supporting a pair of glass sheets 31, 32, Fig. 8, in spaced face-to-face relation in a substantially vertical position, heating tne edge portions of the sneets and bringing these edges together into fusion contact with one another. At a loading station 39, Fig. 5, the sheets are caused to adhere to spaced-apart vacuum platens 56, 57 and, after passing through a preheating zone 163, pass through four fusing zones A, B, C, D in each of which the opposed edge portions at the bottoms of the sheets are subjected to local heating and bending and are caused to fuse together. In passing from each fusing zone to the next the platens and sheets are rotated through 90 degrees (and locked in their new positions) so that each of the four pairs of opposed edges become fused together in turn. The localised heating in the fusion zones comprises burners 164 ; these are followed by pairs of shaping rollers 165, Fig. 8, and by finishing burners 166. The various burners and rollers are adjustable vertically and horizontally and, according to the shape or spacing of the rollers, the fused edges may take any of the forms shown in Figs. 2-4. After passing the annealing zone 227, Fig. 5, the completed units are unloaded at the station 40.

Title: A novel acetoacetate and a process for the manufacture thereof
IPC: C07C69/145
Filed: 1955-02-18
Abstract: The invention comprises di-hydro linalyl aceto acetate and a method for its preparation comprising reacting 6-methyl heptanone-2 with an alkali-metal derivative of acetylene in liquid ammonia solution, treating the product with a non-alkaline hydrolysing agent, such as water, dilute aqueous acid or a non-alkaline ammonium salt, as such or in aqueous solution, partially hydrogenating the resulting 3,7-di-methyl - octin - (1) - ol - (3) in the presence of a palladium or nickel catalyst which selectively catalyses the reduction of a triple bond to a double bond and reacting the so-formed 3,7-dimethyl - octen - (1) - ol - (3) with diketene.  In an example an ethereal solution of 6-methyl heptanone-2 is added dropwise to a liquid ammonia solution of sodium acetylide while passing acetylene therethrough, then the ammonia is removed and the product treated with dilute sulphuric acid and the resulting dihydro dehydro linalool is isolated and hydrogenated in petroleum ether at about 20 DEG  C. using a Lindlar lead-palladium-calcium carbonate catalyst; the so-formed di-hydro linalool is recovered and reacted in petroleum ether with diketene in the presence of minor amounts of pyridine and acetic acid to yield the desired aceto acetate.  The pyridine and acetic acid may be replaced by any other weakly acid agent, e.g. a mixture of choline and acetic acid.  The dihydro linalyl acetoacetate may be used in the production of 6,10-dimethyl-undecanone-2 as described in Specification 788,301.
