Title: Improved method of preparing Ground Cereal Grains in the production of Brewery Mash
IPC: C12C7/01
Filed: 1967-02-17
Abstract: 1,172,552. Hulling and grinding cereal grains. JOHN LABATT Ltd. 17 Feb., 1967 [18 Feb., 1966], No. 7797/67. Heading A2Q. [Also in Division C6] In a process for producing brewer's wort in which cereal grains e.g. malt or unmalted barley, are ground to form a grist, a mash of the grist is formed, the starches in the mash are converted to sugars and the liquid in the converted mash is filtered out as brewers' wort, at least part of the grain is dehulled and the dehulled grain is finely ground. Part of the hulls removed before the grinding may be added to the mash, according to the sharpness or tanginess desired in the finished beer. The dehulling is carried out on a centrifugal scourer - aspirator, the grinding in a roller or impact mill. During the dehulling of malted grains, the acrospires formed just beneath the hull during germination are knocked from the kernel and pulverized and appear in the hull fraction. The proteinaceous acrospire dust can then be separated from the hulls by simple screening.

Title: Preparation of uranium trioxide
IPC: C01G43/025
Filed: 1956-03-13
Abstract: Uranium trioxide is prepared by evaporating an aqueous uranyl nitrate solution to dryness and calcining the dry residue to form the trioxide, wherein a sulfur-containing material from the group consisting of sulfur, thiourea, sulfamic acid, sulfuric acid, ammonium sulfate and hydroxylamine hydrogen sulfate is added to aqueous uranyl nitrate solution, preferably in amounts between 0.1 and 0.5% by weight of the uranyl nitrate hexahydrate.  The uranium trioxide so produced may be reduced with hydrogen in known manner, thereby producing uranium dioxide of increased reactivity with regard to hydrogen fluoride, and so effecting a quantitive conversion of the uranium dioxide to uranium tetrafluoride. According to an example, uranyl nitrate hexahydrate solution containing 0.2% of sulfuric acid in the form of uranyl sulfate, was heated on hot plate at 350 DEG  C. to form solid uranium trioxide. The latter was reduced with hydrogen and hydrofluorinated to obtain a 100% yield of uranium tetrafluoride. The bulk density of the uranium trioxide was 3.69.

Title: Improvements in address-printing machines
IPC: B41L47/46
Filed: 1922-03-20
Abstract: 199,448. Strawn, E. E. March 20, 1922. Pile tables and supports for sheet feeds; sheetseparators.-An addressing-machine of the type in which address plates are removed from a magazine and conveyed to printing position by a rotary carrier is provided with a guide on the frame of the machine coacting with the carrier to hold the plate thereon during conveyance, and with a positively-actuated device for removing the plates from the carrier after printing. An electrical device is also described for preventing the supply of plates to the carrier on breakage of a web of paper passing through the machine. As shown in Fig. 6, curved plates each bearing an address in embossed characters are stored in a magazine 29, the lowest plate resting on two fixed curved strips 30. The rotary carrier consists of a rectangular member 22 mounted on an axle 21 and provided on its sides with oppositely disposed U-shaped magnets 20, which assist in feeding the plates from the magazine and retain them on the carrier during conveyance. The plates are carried on the ends of the member 22 by projections 25 which have shoulders 27, Fig. 11, for detaching the lowest plate, unintentional detachment being prevented by a spring- pressed pivoted finger 31, which also prevents more than one plate being carried forward. The plates are retained on the carrier 22 by circular guides 37, and are carried past inking-rollers 38 and into position to co-operate with an impression roller 16 in printing on a web 18. Stripping-guides 39 direct the plates into concave recesses 43 in rotating discs 40 fixed on an axle 42, on which are also cams 44 adapted to actuate ejectors 45 which remove the plates and stack them in a horizontal magazine 46. Inwardly inclined springs 48 fixed on the sides of the magazine retain the stacked plates vertically. To render the machine inoperative, segmental members 33, mounted on a cross-rod 34, are adapted to raise the address plates out of the path of the plates 25. Projections 36 on the member 22 engage grooves 35 in the members 33 to prevent their upward movement whilst a plate is being detached. A device for automatically raising the members 33 when the web breaks or ends comprises an arm 66, Fig. 14, fixed to the shaft 34 and carrying a core 67 attracted by a solenoid 68 which is energized when a roller 70 normally resting on the web 18 is allowed to engage a contact 71. A releasable pawl 69 retains the arm 66 in the attracted position. In an alternative arrangement, the contact 71 is dispensed with and the motion of the roller arm makes and breaks contact. The rotating parts are driven by gearing from the impression roller 16, the gear wheel from which the shaft 21 is driven being slidably keyed to its shaft to allow for lateral adjustment of the whole machine. The machine normally prints at 11 inch intervals but, to print at intervals of 24 inches, one of the plates 25 is dispensed with and the required retardation is effected by using elliptical gears for driving the shaft 21.

Title: Improved method of making methyl carboxyalkyl ethers of cellulose
IPC: C08B11/12
Filed: 1949-03-28
Abstract: Cellulose fibres are immersed in a 5 to 27.5 per cent aqueous solution of a carboxy alkylating agent, pressed to bring the amount of retained carboxy-alkylating agent within 0.05 to 0.22 parts by weight per weight of cellulose, immersed in a 40 to 55 per cent aqueous sodium hydroxide at a temperature not exceeding 60 DEG  C., pressed to bring the alkali-cellulose ratio within 0.7 to 1.3, then methylated with 1.2 to 1.4 parts by weight of methyl chloride per part of cellulose under pressure below 80 DEG  C., the methylation being stopped before the methylation exceeds 2.1 methoxyl groups per anhydro-glycose unit, the so-formed mixed ether being recovered by treatment with acidified water.  Ethers containing 0.02 to 0.3 carboxyalkyl groups and 0.7 to 2.1 methyl groups per anhydro-glucose unit are so obtained.  The products behave like carboxymethyl cellulose in media having a pH above 6 (i.e. they remain in solution at temperatures up to 90 DEG  C. or higher), and like methyl cellulose when in acid aqueous media of pH 4-2 (i.e. gell at temperatures above about 55 DEG  C.).  Specified carboxyalkylating agents are choroacetic, chloropropionic and chlorobutyric acids and their salts.  In an example a sheet of cotton linters is saturated with a 25 per cent aqueous solution of sodium chloroacetate at room temperature, and pressed to remove excess.  It is then dipped into 50 per cent aqueous sodium hydroxide at 25 DEG  C. and again pressed. After shredding the treated sheet into a pressure vessel, 1-33 times its own weight of methyl chloride is added and the methylation carried out for 10 hours at 60-80 DEG  C.  Excess methyl chloride is driven off, 300 g. of the reaction mixture are stirred into 1700 c.c. of water containing 50 c.c. of concentrated hydrochloric acid at 90 DEG  C. Filtration is carried out in a basket centrifuge and the solids washed with hot distilled water at 75 DEG  C.  After drying, the acid product is spread in a thin layer on a steel pan and sprayed with just enough 25 per cent caustic soda to neutralize the carboxyl groups present.  The product contained 1.45 methoxyl groups and 0.14 carboxymethyl groups per anhydroglucose unit.  Example 3 describes the production of an ether containing 1.83 methoxyl and 0.10 carboxyethyl groups per anhydroglucose unit.

Abstract: 944,639. Indicating clogging of filters. MORRIS MOTORS Ltd. Nov. 8, 1962 [March 6, 1962], No. 8525/62. Heading BID. [Also in Division F2] In a lubricating system for internal combustion engines which incorporate a lubricant filter therein, the clogging of the filter causes a lubricant pressure differential which closes an electrical switch whereby an indicator gives the necessary warning. In an embodiment, a pressure-responsive switch unit 1 is mounted on a filter 4, having a replaceable filter element therein. The filter 4 has lubricant inlet and outlet passages therein and additional passages 11, 13 which connect with passages 10, 14 respectively in the unit 1. A diaphragm 8 of nylon-reinforced nitrile rubber is mounted in the unit 1 and is abutted by a switch-member 18, which is urged by a spring 17 mounted on a spigot 20. Both the spring 17 and the spigot 20 are insulated from a fixed switch-member 21. In use, oil is supplied from the engine by a pipe 12 and a quantity is by-passed into an annular channel leading to the passages 11, 10 so as to impinge against one side of the diaphragm 8. Filtered oil enters the passages 13, 14, passes through a hole 15 in the diaphragm and impinges on the other side of the diaphragm. When the filter element 5 is clogged, the pressure in the passages 13, 14 is lowered and the diaphragm is deflected, thus allowing the switch-members 18, 21 to make contact so that current can pass through a terminal 22 and light a warning lamp on the instrument panel of the vehicle.

Abstract: 390,945. Safety razors. LONG, J., 355, Rattray Street, Dunedin, Otago, New Zealand. March 23, 1932, No. 8640. [Class 30.] The clamping plate 1 of a safety-razor is hinged about one of its longitudinal edges to a corresponding edge of the usual toothed guard 6 in such a manner that both cutting edges of the usual flexible blade are available for shaving at any one time. The hinging means comprise pins passing through lugs on the ends of the clamping plate and lugs 8 on the guard. The clamping plate has a central threaded stud 2 which passes through the blade and guard and engages a member 19 rotatable and slidable within a sleeve 13 on the handle 12. A pin 22 passing through a spindle 17 engages a slot 21 in the member 19 so that limited relative longitudinal movement between the members 17, 19 is permitted. Additional lugs on the remaining corners of the clamping plate 1 assist in positioning the blade. A shoulder 23 on the member 19 abuts the sleeve 13 when the blade is clamped. The spindle 17 passes through a bearing 16 and is prevented from falling out of the handle by a collar 30 or alternatively by a flange on the upper end of the member 19. The guard 6 may have a series of long narrow slots instead of the usual teeth. In a modification, the spindle 17 is integral with the member 19 and the bearing 16 is replaced by an integral enlargement of the spindle 17 near its base which either slides or screws in the handle 12. In a further modification, the spindle is omitted and the handle 12 which is pinned to the member 19 rotates relatively to the sleeve 13. In this case, the member 19 does not move longitudinally. The hinging lugs on the clamping member 1 may have slots to permit slight vertical movement of the clamping plate.
