Title: Improvements relating to the conditioning of grain
IPC: B02B1/04
Filed: 1929-12-12
Abstract: 344,538. Conditioning grain. HALL, J. A., 66, Goldington Avenue, Bedford, and GEORGE, W. F. C., Wilby, Welling- borough, Northamptonshire. Dec. 12, 1929, No. 38108. [Class 58.] Grain while falling from a hopper b through a conditioning tower a in which it is subjected to the action of air circulated by a fan f through chests communicating with superposed rows of ducts c, d, open at their lower sides so that the air passes from the ducts of one row to those of another, is also subjected to the action of chemical media or gases such as chlorine, ammonia, formaldehyde or compounds of chlorine, sulphur and ammonia which are introduced into the circulating air. Solutions may be added to the grain in the hopper, such solutions being vaporized by warm circulating air. In the form shown the chemical medium is injected into the circulating air by nozzles j. In another form the medium may be fed from a cylinder through a measuring device to the air circuit or it may be vaporized from a trough as the air passes ; steam may also be injected to add moisture to the air. In a further modification the grain while falling down a shoot to the hopper actuates a pump supplying liquid to the grain.

Abstract: 1,262,910. Pneumatic cleaning device. NORTECH. CORP. 31 July, 1969 [21 Nov., 1968], No. 38534/69. Heading F2N. A device for cleaning a pneumatic tool includes a pneumatic circuit that is used, selectively, to pressurize the cleaning solvent reservoir of the device and force solvent through the tool, and to supply air through the tool to clean it during its normal operating cycle. The pneumatic tool 8 is placed on a shock-absorbing support in a cabinet mounted on a partitioned base structure 20. Compressed air is directed by a 3-way control valve 48 into a cleaning solvent reservoir tank 22 via conduits 38, 46, 50. Solvent is forced along a conduit 58 and directed by a control valve 36 through a hose 42 and into the air inlet of the pneumatic tool 8. The solvent flushes from the exhaust opening of the tool to collect in the cabinet sump 26 and flows through a ball valve 35 into a drain tank 24, from which air escapes through a bleed valve 56. Valve 36 is then adjusted to block off the flow of solvent and direct compressed air through the hose 42 and the tool 8 to switch the tool on. The reservoir 22 can be replenished by adjusting valve 48 to direct compressed air through conduit 52 into the drain tank 24, to force the dirty solvent through a filter 62 and back into the main reservoir 22.

Compounds of the formula wherein Ac represents an aryl group, X represents the disubstituted carbon atom of the thiazolidine ring and R a  represents the residue of an alcohol, and isomers and tautomers thereof, may be obtained by reacting an N 1 -unsubstituted 4,4 - disubstituted 3 - acyl - azetidino- [3,2-d]-thiazolidine-2-one of the formula with a diformylmethylene-methane carboxylic acid ester of the formula The reaction is suitably effected in such a manner that decomposition of the olefin is avoided, e.g. at room temperature or by heating to temperatures up to 180‹C., optionally in the presence of a diluent and/or condensing agent and optionally in an inert gas atmosphere and/or under superatmospheric pressure, and the starting materials may be prepared in situ. The products may exist in tautomeric forms and the mixture of isomers obtained from the reaction may be resolved by conventional methods, e.g. fractional crystallization, adsorption chromatography or by forming a mixture of diastereoisomeric salts with optically active salt-forming agents and subsequently breaking down said salts and converting the isolated salts into the free compounds. The specific examples relate to the preparation of 3-tert-butyloxy-carbonyl - α - diformylmethyl - 4,4 - dimethyl - 2 - oxo - 1 - azetidino - [3,2-d] - thiazolidine acetic acid 2,2,2-trichloroethyl ester and the separation of isomers thereof.

Abstract: 1,085,801. Vulcanizing. W. SCHELKMANN. Sept. 22, 1964, No. 38687/64. Heading B7C. A profiled pre-vulcanized tread strip 2 is vulcanized on to a tyre carcass 1 with the interposition of an unvulcanized rubber bonding plate 3 by enclosing the whole in a sheath 4 and then subjecting the assembly to pressure and heat, the pressure within the sheath being of the order of 1 atmosphere lower than that exerted on the outside of it. As shown in Fig. 2, a wire mesh 5 is inserted between the sheath 4 and the strip 2. An airtight closure of the sheath is effected by a lipped sealing element 9 which is as shown integral with the sheath, or may be vulcanized to the sheath or separate therefrom. The vulcanizing of the plate 3 and strip 2 to the carcass 1 takes place in a pressure chamber 14 subjected to an hydraulic pressure by means of a valve 16, the liquid being heated by a source 18, the pressure within the sheath 4 being controlled through pipes 15 which are connected by a two-way valve 42 to a suction pipe 43 and a pressure pipe 44. The pressures may be equalized after the marginal regions of the strip are firmly bonded to the tyre. The pressure within the chamber 14 may be provided by gas under pressure. The effect of the pressure differential is stated to reduce the tendency of buckling of the tread strip 2 and plate 3 due to action of the outside pressure on the profiles of the strip 3.

Title: Crystalline zeolite
IPC: C01B39/46
Filed: 1958-12-11
Abstract: A synthetic, zeolite aluminosilicate molecular sieve, designated zeolite E, of general formula: <FORM:0905194/III/1> having a characteristic X-ray powder diffraction pattern and wherein M is at least one metal of Group I and II of the Periodic Table, hydrogen or ammonium and n is the valence thereof, is prepared by first forming a sodium/potassium zeolite E wherein <FORM:0905194/III/2> in the above formula is xK2O:(1-x)Na2O, x being 0,5 to 0,8, and thereafter producing the desired zeolite by ion exchange of the potassium/sodium form so produced.  The potassium/sodium zeolite E is prepared by dissolving sodium aluminate and sodium and potassium hydroxide in water and adding this solution to an aqueous sodium silicate solution, preferably at least in part derived from an aqueous colloidal silica sol. Such a mixture preferably has a composition such that Na2O/(K2O + Na2O) is 0,5, (K2O + Na2O)/SiO2 is 0,8, SiO2/Al2O2 is 2 and H2O/(K2O+ Na2O) is 20.  The mixture is heated from 75 to 120 DEG  C. until crystallization of the zeolite occurs, a preferred temperature being 100 DEG  C.  The zeolite crystals are washed until the effluent wash water pH is about 10. According to Examples, (I) alumina trihydrate was dissolved in a mixture of potassium and sodium hydroxides and the solution added to an aqueous silica sol, the mixture was sealed in a glass jar and heated at 100 DEG  C. for 64 hours and the crystalline product which settled was filtered; it had an analysis of 0,61K2O: 0,25Na2O:Al2O3:2,03SiO2:3,5H2O and was in the form of cubes having 2 to 4 microns particle size. Reference is made to ion exchanging with a solution of calcium, lithium, magnesium zinc and ammonium chloride, sulphate or nitrate solutions, preferably at pH of 5-12.  The zeolite may be employed as an adsorbent after partial dehydration at about 130 DEG  C. under vacuum.  Absorption data are given for the absorption capacity of zeolite E for water vapour, oxygen, carbon dioxide, ethylene and sulphur dioxide, the absorption of water being improved by calcium, magnesium or lithium exchange.  The zeolite may be employed in powder form or may be pelleted with a binding agent such as clay.
