Title: A new and improved machine for applying powders to printed sheets
Inventor: GLADWELL DANIEL
IPC: B41F23/06
Filed: 1954-10-12
Abstract: 766,727. Bronzing and the like. SELWYN PRESS, Ltd. Sept. 28, 1955 [Oct. 12, 1954], No. 29368/54. Classes 100(1) and 100(2) A machine for applying powders, e.g. fusible thermosetting powders or bronzing or chalk powders, to printed sheets, comprises a device which collects the powder from a container situated below the travelling sheet and deposits it on the printed surface of the sheet in such manner that the deposited powder is distributed over the printed surface and surplus powder is returned to the container. Printed sheets are stacked, printed face down, on a platform 3, Fig. 2, and fed between conveyer bands 8, 10, thereupon passing in succession over a support 4 comprising a grid 4a, Fig. 3, having an upwardly inclined portion 5a, over a sloping grid 5b forming part of a support 5, and thence over a heated bed 6 and a cooled bed 7. A shaft 24, Figs. 2, 3 and 4, is driven by an electric motor through a belt drive, a shaft 19, and gears 28, 29, and carries a three-limbed spider 23, each limb of which carries a powder pick-up arm 26 of irregular polygonal form. Each arm moves down into a container 22 for a powder, such as a thermosetting resinous powder, bronzing powder, or chalk, and then rises through a gap 21 between the two grids, carrying powder on its upper surface. As the arm moves upwards, thereby tilting, the powder falls on to a sheet near its leading edge, and as the sheet moves up the grid 5b the powder is distributed by gravity over the surface of the sheet, surplus powder falling back into the container. To adjust the amount of powder applied, each arm 26 can be secured to its spider limb with any of its surfaces, which are all of different areas, in position to be the powder-carrying surface. The bed 6 is provided. with perforations aligned with suction openings in a suction box below the bed. Electric heating elements are located between the bed and the box. The air between the sheet and the bed is thus removed to facilitate heating. The upper surfaces of the sheets are heated by infrared lamps 34. The bed 7 is in the form of a box through which a cooling medium is circulated, and may have suction passages connected to an exhauster or suction fan. According to the Provisional Specification the sheets may be vibrated while passing up the grid to facilitate powder distribution. Feeding sheets. A suction tube 12, Fig. 2, having spaced suction-nozzles 13 is mounted on an axle 14, which is reciprocated horizontally from the shaft 19 by crank mechanism 17, 18; gears 15 at each end of the shaft running on racks 16 between which the pile of sheets rests, cause the shaft to oscillate as it reciprocates, whereby the top sheet is engaged near its left-hand edge, rolled over, and fastened upside-down to the. belts 8, 10.
Patent GB-760191-A (GB)
Title: Sulphur dioxide leaching of uranium containing material
IPC: C22B60/02
Filed: 1954-10-12
Abstract: Uranium is recovered from iron-free finely divided material containing uranium at least in part in the tetravalent form by leaching the material with an aqueous solution containing sulphur dioxide in the presence of a soluble ferric or ferrous salt, and/or a soluble manganese salt, the solution being aerated during the leaching.  The solution should contain 1-2 grams of iron per litre as a soluble salt or 0.5-1 grams of manganese sulphate per litre.  After separation from the undissolved residue the uranium may be precipitated from the solution by adjusting the pH to 1.25 and adding iron powder in the presence of a soluble phosphate, arsenate or fluoride.  The uranium material employed which may contain hexavalent uranium, such as pitch blende and may be constituted by uranium ore or mill tailings, is first freed of free iron by magnetic separation and thereafter formed into a pulp having a liquid solid ratio of from 1:1 to 2:1 with an aqueous sulphur dioxide solution made from water or barren recycled solution by introducing sulphur dioxide from a sulphur burner or roaster or from return processed gas, thereinto. The pulp is agitated with air at atmospheric temperature and pressure in the presence of the soluble iron or manganese salt preferably as sulphate, and the pH of the solution maintained at 1-2 by the addition preferably intermittently, of sulphur dioxide gas.  The aeration should be controlled to avoid excessive removal of sulphur dioxide.  If desired the leaching may be effected by percolating an aqueous solution containing sulphur dioxide with aeration through a bed of the material.  In either event the resulting solution, after filtration if necessary, is adjusted to pH 1.25 by the addition of sulphur dioxide gas, and the soluble phosphate fluoride or arsenate is added together with finely divided iron powder.  The precipitated slurry is treated to remove magnetically the excess metallic iron and the resulting slurry is vacuum filtered to recover excess sulphur dioxide which may be recycled to the precipitation step.

Patent GB-511032-A (GB)
Title: Method for the control of proteolytic activity in the manufacture of baked goods
IPC: A21D8/04
Filed: 1937-11-06
Abstract: 511,032. Food preparations ; enzymes. STANDARD BRANDS, Inc. Nov. 6, 1937, No. 29743. Convention date, Nov. 7, 1936. [Class 49] [Also in Group IV] In making baked products from dough ingredients containing proteolytic enzymes, the ingredients are placed in a container which is then evacuated and oxygen added in predetermined amount to control the activity of the enzymes during the formation of the dough which is then effected, the activity being decreased as the amount of oxygen added is increased. The dough formed is subsequently handled and baked in the usual manner. Substances, such as ascorbic acid, capable of taking up oxygen and transferring it to the enzymic material may be included with the dough ingredients. The dough may contain an added proteolytic enzyme material, e.g., papain. By the process a flour weak due to high proteolytic activity may be used in making baking products having the characteristics of a strong flour. The Specification as open to inspection under Sect. 91, comprises also the control of the activity of proteolytic enzymes generally, e.g., those present in malt products, flours and arising from the growth of various moulds, by regulating the oxygen content of their environment, the oxygen content being increased to decrease their activity. The oxygen content may be regulated by removing the surrounding air by evacuation to the desired extent followed by introduction of oxygen-containing gas, which may be oxygen or air enriched with oxygen. A pressure greater than atmospheric may be employed. The regulation may also be effected by adding to the materials being treated compounds containing loosely combined oxygen, e.g., innocuous halogen compounds such as chlorates, perchlorates, bromates, perbromates, iodates or periodates, persulphates, percarbonates, perphosphates, peracetates, or calcium, magnesiu, hydrogen and like peroxides. Preferably the sodium, potassium or ammonium salts are used. In making baked goods, a material containing proteolytic enzymes and a compound containing loosely-combined oxygen may be included and the release of oxygen may be facilitated by adding a catalyst such as sodium ortho- or metavandate, vanadyl sulphate or divanadyl chloride or other watersoluble vanadium coumpounds. Examples are given of the addition of papain and potassium bromate to dough, the proteolytic activity being diminished and the volume of the loaf increased as the amount of bromate is increased. Oxygen carriers, such as ascorbic acid, may be included to enhance the effect of the oxygen. In further examples, the effect of mixing dough containing papain in air is compared to that obtained by mixing in carbon dioxide or nitrogen. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in addressing and the like printing machines
IPC: B41L47/24
Filed: 1923-11-27
Abstract: 222,002. Marks, E. C. R., (Adrema Maschinenbau-Ges.). Nov. 27, 1923. Addressing a n d l i k e machines ; tripping-arrangements.-Relates to addressing and like printing machines in which the addresses are printed through stencils by an impression pad g carried by a lever d, and the impression pad is moved into and out of printing position by a cam roller l and springs 16, and consists in the provision of means where'by mechanism operated from the lever d for feeding a listing strip h is controlled from the cam roller l so that no feed takes place when the pad g is out of printing position. The end of the strip h is clamped to a slide 1 carrying a pawl o engaging a rack m adapted to be reciprocated by a segmental gear n operated from the lever d so as to feed the strip transversely to the path of the printing- stencils c. Oscillation of the gear n is obtained through a link r pivoted to a two-part member t, u<1> which is in turn pivoted at v to the lever d. The parts t u<1> are connected together to feed the strip or can slide one on the other so that no feed takes place according as the cam roller l in the impression head 9 is in position for printing or not. For this purpose, the part u<1> is tubular at u, and the part t can slide therein, the part u<1> carrying a pivoted member in two parts 52, 53 spring-pressed apart, and on which is formed a projection 32 normally kept out of engagement with a notch 33 in the part t by the fact that the part 52 is heavier than the part 53. Engagement of the projection 32 with the notch 33 is effected by means of a member 27 pivoted at 28 to the part u' and at 26 to a rod 21 attached to the cam roller l. When the roller l is turned to printing position, the member 27 is moved to the position shown in the Fig. 7 where it engages the member 53 and tends to force the projection 32 into the notch 33 in the part t, the spring 54 between the parts 52, 53 allowing the projection to snap into the notch 33 as the part u<1> slides relatively to the part t on the downward movement of the printing lever. When the parts of the link u<1>, t are so connected together, the upward movement of the lever d serves to actuate the stripfeed mechanism. As applied to a machine in which the cam lever l as automatically moved into printing position on depression of the lever d if a stencil is in printing position beneath it, the rod 21 is pivoted to an arm 66 which is connected by links 65, 64. 63 to the roller l, the link 64 being pivoted to the lever d. The arm 66 is mounted on the same shaft 67 as the lever d, and moves with the lever unless a stencil is in printing position, when its movement is prevented. On depressing the lever d when the arm 66 is locked, the links 63, 64, 65 rotate the cam roller l to printing position and the rod 21 throws the member 27 into position for connecting the parts of the link u<1>, t, so as to enable the strip to be fed.
