The container is mounted for rotation in the upper part of a -housing 10 above an impeller 28 having blades for shot received from a hopper 42 upwardly towards the container, the impeller being driven by a belt 36 from a motor 38. The container consists of end plates 50 which are mounted by couplings 80 on shafts 82 and interconnected by rods 52. The wall 54 consisting of expanded metal or wire mesh extends around the rods to form the container. Inner rods 56 and divider walls also of expanded metal or wire mesh divide the container into compartments, and each compartment has its own hinged door 62 for permitting loading and unloading of articles into the compartments; the workpieces loaded into one compartment may be of a different size to those loaded into another so that heavy workpieces do not damage lighter workpieces during tumbling. According to the size of the workpieces, the rods 54, 56 may be spaced to prevent passage of workpieces therebetween in which case the expanded metal or wire mesh 54, 60 maybe dispensed with. The container is driven by a belt 90 from a motor which also drives an air lock 95 of a cyclone tank 94 having an inlet conduit 96 for receiving shot and dust from the housing 10 and a conduit 98 for returning shot to the housing. Dust is passed to a collector 102 by a fan 104 in a conduit 100 connected to the upper end of the cyclone. In another embodiment, the rods between the discs of the container are easily adjustable to form compartments of different sizes and wire mesh screens may be placed in radial planes of the container to form smaller axially arranged partitions.

Title: Method and apparatus for separating materials by continuous liquid thermal diffusion
Inventor: JONES ARTHUR LETCHER
IPC: B01D17/00
Filed: 1953-06-04
Abstract: <PICT:0733580/III/1> <PICT:0733580/III/2> In the continuous separation of liquids by thermal diffusion, the liquid is passed through a narrow uniform slit formed between two walls spaced equidistantly apart at about 0.01-0.15 inch and maintained at different temperatures, a liquid-permeable membrane being arranged intermediate and parallel to the wall faces; liquid is fed into the space between the membrane and one of the walls, and one fraction is withdrawn from a point remote from the inlet on the same side of the membrane, and another fraction from the space on the other side of the membrane.  In Fig. 1 the membrane 16 is arranged between two wall faces 17, 24 which are cooled and heated respectively by jackets 31, 36.  Inlet and outlet ports 21, 22, 29, 30 are provided at the ends of the slit or at an intermediate point 40.  In Fig. 28 (not shown) two slits have their hot walls arranged back to back and heated by an electric resistance element.  Fig. 29 shows apparatus in which the slit-forming surfaces are in tubular form, membranes 52 being interposed between the surfaces of tubes 46, 47; the liquid treated and the fractions withdrawn flow through lines 61, 62, 64, 66, and heating or cooling media are circulated via lines 67, 69, 70, 71. The walls are made from material which is liquid impervious, heat conductive, and unreactive with the substances being separated; suitable materials are stainless steel, copper, aluminium, glass, brass and other alloys.  Membranes may consist of paper (e.g. duplicator or tracing), a film of bentonite clay, a thin sheet of porous stainless steel, or a laminate of fibre glass impregnated with a clay filler.  The slit may be in a vertical, horizontal, or inclined position; one of the fractions withdrawn may be passed to a second slit for further separation, and so on. A series of diagrams show various arrangements of input and withdrawal ports, and flow patterns for multiple slit operation. The directions of introduction and withdrawal are preferably such as not to interfere with thermal circulation within the slit; the rate of flow of liquid may, however, be greater than that of thermal circulation.  Graphs show the relationship between the degree of separation and the feed rate, with different wall face areas, membranes and flow patterns; results obtained using slits without membrances are included for comparison. Examples relate to the separation of mixtures of cetane and methyl naphthalene, benzyl alcohol and ethylene glycol, and a petroleum lubricating oil into fractions of different viscosities.  Reference is also made to the separation of isomeric hydrocarbons, vegetable oils, fats, and waxes, hormones, viruses, antibiotics and vitamins.

Class 123(1) A device for automatically indicating the critical oil level in oil sumps of engines comprises a metal tube 12 which is vertically secured by a screw 20 to a crank-case oil sump 22 and accommodates a freely movable metal float 24 in an upper cage-like portion formed by rods 10 and an end plate 11. An electrical contact nipple 13 is fitted within, and electrically insulated by a sleeve 16 from, the lower end of the tube 12 which is secured to the sump 22 by the screw 20. The latter, engaging a thread in the nipple 13, passes through a hole in the sump 22, from which it is electrically insulated by members 17-19, and carries a plug contact 21 leading to a battery and a signalling apparatus, not shown.

In use when the oil drops to a critical level the float 24, resting upon the nipple 13, leans on the rods 10 and closes the circuit from the battery to the signalling device. Passages 15 through the nipple 13 and the tube 12 prevent oil suction below the float 24 when the oil rises.

An apparatus deposits articles such as tablets into the recesses of a horizontal moving web by agitating the articles on the web surface to cause them to fill the recesses. As described, tablets from a hopper (19) (Fig. 3, not shown) are fed into a filling station (3) through grooves (16) (Fig. 4, not shown) of a rotating brush (14) on to a moving web surface (1), where the tablets are agitated by revolution of flexible fingers (11) attached to a horizontally revolving plate (7) to cause the tablets to fill the recesses in the web (1). Revolution of the plate (7) also laterally moves the side walls (13) of the filling station (3), the tablets being prevented from leaving the filling station by means of a rotating brush (15). The web (1) is moved forward an increment at a time by the movement of a yoke member (2) (Fig. 1, not shown) which operates pneumatic grippers (not shown). During the web movement, the filling station (3) is also moved forward at a slower speed and a smaller distance than the web (1) by means of a chain (21) passing round a sprocket (20), one end of the chain attached to the yoke member (2) and the other end to a fixed member (23). During the return stroke of the yoke (2) the station (3) is returned to its initial position by means of a spring (24). The side walls (13) may alternatively be secured to the filling station (3) and not actuated by revolution of the plate (7). Longitudinal walls, aligned with the grooves (16) of the brush (14), may also be attached to the side walls (13) to form separate tablet lanes.
