[Class 59] In a mill in which the material is oscillated between the end walls of a perforated container the material is fed automatically in a continuous manner to the container which is filled for a substantial portion of its length by the load. As shown, an arcuate chamber 271 is suspended on arms 257 carried by a hollow boss 254 secured to a drive shaft 240 having an arm 238 connected by a rod 235 to a crank-pin on an eccentrically mounted disc which is movable to vary the throw of the crank. An extension of the crank-pin engages a shaft 332, the pinions 330 of which drive a rotary elevator 320. The chamber 271 is perforated at the bottom and may be perforated at the top and sides, it is connected to the boss 254 by a flared feed aperture 260 supplied with material through a feed shoot 297 in the drum 207 enclosing the reciprocating chamber 271. The elevator 320 is divided into three parts, the centre part 325 not communicating with the material discharged from the camber 271, this material passing through slots in the bottom of the cylinder 207 into the two side compartments of the conveyer. The disintegrated material raised by the conveyer is in part carried off by an air stream to a sifting device and the coarse material left passes through slots 306 in the top of the drum and reenters with the feed whilst the coarse material deposited by the sifter falls into the central part 325 of the conveyer and is moved round into the feed shoot 297 together with any coarse material left in the sides 323 of the conveyer. The walls of the chamber 271 may be made up of thin plates or plates with notched sides. The air discharge pipe to the separator may be divided by partitions forming separate outlets each controlled by a pivoted flap.

Oct.14, 1960 [Jan. 25, 1960], No. 35241/60. Heading H2A. The operation of a magnetohydrodynamic generator is improved by graduating the length of the electrode segments 14-18, 19-23, so that they pierce the boundary layers of cold non-conductive gas 17, 25 and are in good conductive contact with the ionized gas. Various connections are described, either as shown, where all segments are connected in parallel with the load, or having opposed pairs of segments connected through inverters to a transformer, Fig. 3 (not shown). The latter connection ensures that the current collected by each electrode is the same and eliminates hotspots. The whole cross-sectional area of the duct is used by having a number of paralleled segments, spaced apart in a plane transverse to the direction of fluid flow. The electrodes may be made from refractory metals, stainless steel or from copper, if internal cooling is provided. The principle may also be applied to a pump. Specification 966,968 is referred to.
