Abstract: 734,411. Malt-turners. FAWCETT, Ltd., E., and WHITE, H. May 20, 1953 [Feb. 21, 1952; Aug. 13, 1952], Nos. 4566/52 and 20312/52. Class 86. A malt-turner consists of one or more inclined pick-up devices arranged to scrape the grain off the floor as the machine is propelled forwards, and a driven feeder-beater device rotatable about a horizontal axis and having blades arranged to co-operate with the pick-up device without touching the floor so as to assist in picking up the grain and to feed the picked up grain through or into the machine and turn and beat it before it is deposited behind the machine. The machine shown in Fig. 1 is supported upon the floor by the pick-up device which comprises a scraper 6, and is manually propelled by means of a draw-bar 3 and handle 4. The feeder-beater 7 which assists in picking up and beats the grain and deposits it behind the machine, is driven by a motor 11 in a clockwise direction, the reaction between the grain and the feeder-beater blades 8 being such as to assist in propelling the machine forwardly. In alternative embodiments, Fig. 4 (not shown), and Fig. 5, the machine is mounted on wheels 21, 22 and is mechanically propelled, and the feeder-beater 29 feeds grain from the pick-up device 24 at the front of the machine to a clockwise driven beater distributer 36 having blades 37 which deposit the grain behind the machine. An angularly-adjustable discharge guide 41 is provided whereby the angle of discharge and hence the distance of throw of the grain may be varied. Compressed air jets 46 may be directed down on to the floor in advance of the wheels to blow out of their path any grain to prevent crushing thereof. The pick-up device, 6 or 24, may be a single scraper blade, or may be built up from a number of individually movable segments 25, Fig. 6, urged against the floor by springs 28. The feeder beater 7 of Fig. 1 and the beater distributer 36 of Fig. 5 may be driven at speeds variable at will, when the thickness of the layer of grain deposited behind the machine may be increased or decreased respectively, by increasing or decreasing this speed during traverse of the machine. In the machine described in the second Provisional Specification the grain is thrown behind the machine by a rotatable beater which co-operates with an inclined pick-up device, and the machine is mounted on wheels which may or may not be mechanically driven. In the machine described in the first Provisional Specification, a first rotary beater co-operating with an inclined pick-up device feeds grain to a second rotary beater at the rear which discharges the grain rearwardly, but means are also provided for causing the grain to pass from the machine before it reaches the second beater so that the grain may be deposited back on the same part of the floor from which it was taken. The pick-up of grain may be assisted by brushes or by pneumatic means, and the path in front of the wheels may be cleared of grain by means of brushes. 734,459. Centrifugal separators. STAMICARBON N.V. June 18, 1953 [June 19, 1952], No. 16880/53. Class 23. Froth is separated into liquid and gas in a radially symmetrical chamber 6 having a gas inlet 7 arranged to form a gas vortex within the chamber, a froth inlet 5 for introducing the froth to the core of the gas vortex, and an axial outlet 8 for discharge of the separated components. The chamber is glass and, as shown, the gas inlet is a tangential pipe, but chambers having axial inlets with rotation inducing vanes
