Title: Process for preparing powdered yeast product
Inventor: PARKER RICHARD BENNETT
IPC: C12N1/00
Filed: 1959-02-04
Abstract: 889,979. Yeast food preparations. GENERAL MILK CO. Feb. 4, 1959, No. 3912/59. Classes 14 (2) and 49. A method of manufacturing a yeast product comprises moistening the individual particles of dried yeast to an extent sufficient to render them sticky, causing the sticky particles to adhere together in the form of random aggregates of a size substantially greater than the size of the individual particles and then removing the excess moisture, the product flows freely and can be readily dispersed in water when required. In the apparatus shown dried yeast powder, which may first be mixed with dried milk, is fed through an inlet 14 into a chamber 13. The chamber is heated by warm air passed through a jacket 18 and air is removed through a conduit 15 to induce a flow through the opening 16 between the chamber and the discharge cone 17. In the zone 19 the yeast meets atomized water from a nozzle 20 and wet steam from nozzles 21. The moistened and aggregated yeast particles are discharged from the cone 17 on to a conveyer 22 which removes them for drying. Specification 753,600 is referred to.

Title: An improved machine for classifying, according to weight, thin sheets of all kinds of materials
IPC: B07C5/18
Filed: 1926-02-11
Abstract: 261,957. Etablissements J. J. Carnaud et Forges de Basse-Indre. Dec. 28, 1925, [Convention date]. Sorting by weighing.-In a machine for automatically classifying thin plates according to their weight the plates are fed successively to the pan of a balance which positions a finger in front of a series of slides according to the depression of the pan, and means are provided for causing the finger to pull out the selected slide and thereby open a path to a corresponding shelf to which the plate is transferred. The machine is driven by an electric motor and its operation is controlled by cams on a shaft O<1>. The plates, resting on a table A, are fed forward singly, by hand or by automatic means, as far as a stop 1 which is withdrawn as a roller F, on rising beneath the plate, presses it against a continuouslyrotating roller B. The plate is thus fed on to a grid T which then sinks and deposits the plate upon the scale pan U. The scale pa.n descends until counterbalanced by weights picked up by the weigh beam. A hooked finger V suspended from the pan is thus positioned vertically in relation to a series of superposed slides X, and is drawn back by a pulling member Y so as to draw out the selected slide. The slide in turn actuates a bell-crank S' and pulls down a corresponding rod Z. The rod Z trips a catch and thereby allows a spring C<1> to rotate a corresponding shutter D' so that the curved under surface of the shutter crosses the path of the plate as it is subsequently fed upwards between a series of continuously-rotating rollers I<1>, I<2>, thus causing the plate to be deflected on to the corresponding shelf k. The shutter is afterwards returned to its normal position by the rise of a camoperated rod P<1>. The plates are fed from the weigh pan to the rollers I<1>, I<2> by a vertically-reciprocating roller G' and a continuously-rotating roller F', assisted by a curved guide H<1>.

Abstract: 114,204. Gill, H. A., [Jobbins, Inc., W. F.). March 26, 1917. Ammonia; aluminium nitride. - Aluminium skimmings, dross, slag, &c., after first separating the larger metallic particles, are mixed with a reducing agent such as tar, asphalt, petroleum, resin oil or like hydrocarbon material and heated with exclusion of nitrogen to a nitride-forming temperature (1200‹ C.) after which a nitrogenous gas such as air is admitted when nitrogen is absorbed to some extent and the temperature rises. On cooling, the smaller metallic particles will be found to have fused together so that they can be removed.

[Class 138 (ii)] The roller 14 is loosely mounted on a tubular arm 13 so as to be movable transversely. It is normally maintained by springs 26 in an elevated position with respect to the arm whereby an internally toothed gear wheel 30 formed within its periphery is held out of engagement with a driving pinion 31. When the concave bed 35 is moved into operative engagement with the roller the initial contact overcomes the force of the springs and depresses the roller above the arm 13 whereby the gear wheel 30 is caused to engage the driving pinion. The bed is moved by an arrangement of toggles 38, 41 operated by a lever 43 pivoted about an arm 33. When it is desired to move the bed into contact with the roller without causing the roller to rotate, the latter is held in elevated position with respect to the arm 13 by means of a slide 50 actuated by a handle 50a so that it may be pushed inwards so that a blank 53 carried thereby is inserted between the arm 13 and the sleeve 22 on which the roller is supported. The arm 33 is made sufficiently resilient to compensate for varying thicknesses of goods being ironed. The toothed gears 30, 31 may be replaced by friction wheels.
