IPC: A61J3/06
Filed: 1927-01-17
Abstract: 282,994. Linebarger, C. E. Jan. 17, 1927. Casting-apparatus; moulding - machines. - Pellets or balls of substances melting at fairly low temperatures, such as a mixture of chlorinated naphthalene, stearic acid, and carnauba wax, are manufactured by melting the substance and allowing streams of the molten substance to flow through a liquid which is at a temperature higher than the melting point of the substance, thus forming drops of the substance, then passing the drops through a liquid which is at a lower temperature, and finally through a third liquid which is at a temperature lower than the melting point of the substance. As shown, the substance is melted in a vessel 8, Fig. 2, heated by steam or a hot liquid passing through a coiled pipe 9, and runs down through a valve 10 into a vessel 5 where the level of the molten substance is kept constant by means of a float 11 controlling the valve 10. The level can be adjusted by raising or lowering the vessel 8. The vessel 5 is heated by means of a coiled pipe 6, and the coiled pipes 6, 9 are surrounded by insulating covers 7. The molten substance passes from the vessel 5 through short tubes 15 fitted with nozzles 28 and regulating valves 31, and falls in small streams into the top layer of liquid in a vessel 13, Fig. 1. This vessel is heated by a bath 21 containing water at about 80‹ F. up to the level of the bottom layer of low temperature in the vessel 13, and the, upper part of the vessel 13 is further heated to about 212‹ F. by a coiled pipe 26. The liquid in the vessel 13 may be a solution of calcium chloride, and its density is adjusted as well as its temperature to produce the desired drop formation and size and shape of pellet or ball, which results also depend on the size of the nozzles 28 and the adjustment of the valves 31. Liquid may be run off the vessel 13 and bath 21 by taps 25, 22 ; and fresh liquid may be added to the vessel 13 by funnels 23, 24, 33. The level of the liquid in the vessel 13 is determined by an ovexflow outlet 34, which car be adjusted by sliding the funnel 33 up or down the tubular stem 20.

Abstract: 733,504. Counting-apparatus.MEASUREMETERS CO., Ltd., and MORRIS, Ltd., R. Jan. 18, 1964 [Jan. 17, 1953]; No. 1426/53. Class 106 (1). An apparatus for registering and displaying details of multiple-item sales involving, for example, bags of coal, volumes of liquid or lengths of fabric, comprises a trip counter for the items in the form of a pointer D<SP>1</SP> rotatable over a graduated dial D<SP>2</SP> and adapted to be reset at the conclusion of each transaction, a total counter G and a counter H actuated each time the pointer D<SP>1</SP> is reset and so registering the number of sales. The pointer D<SP>1</SP> and total counter G are both actuated from a shaft A which is adapted to be oscillated at each item delivery. The counter H is actuated by the reset shaft F for the pointer. The shaft A oscillates an intermediate shaft B through a link a<SP>1</SP>, the shaft B actuating the total counter G through a further link g<SP>1</SP>. The oscillations of shaft B step forwardly a pinion b<SP>1</SP> which drives a shaft C connected through bevel gears c<SP>1</SP>, d with the pointer shaft D. The shaft C is displaceable axially against a spring c<SP>2</SP> to disengage the bevel gears for resetting the pointer. This movement of the shaft is effected by an arm e of a three-armed lever adapted to be rocked by a cam f on the reset shaft F. The three-armed lever also actuates the counter H through a link e<SP>2</SP> and, in order to prevent more than one advance of this counter should the reset shaft F be'repeatedly rotated, a spring-actuated locking lever K snaps behind and holds the three-armed lever when moved by the cam f, and the threearmed lever is not released for further actuation until the lever K is reset by a cam a<SP>2</SP> on the shaft A at the next item delivery. Resetting of the painter D<SP>1</SP> is effected by a torsion spring d<SP>5</SP> and a gear train d<SP>2</SP>, d<SP>3</SP>, d'. A track gap in the gear d<SP>2</SP> prevents overwinding of the spring by advance of the pointer through more than one revolution.

Title: Grinding and pulverizing method and apparatus
IPC: B02C19/00
Filed: 1947-01-17
Abstract: 639,050. Impact pulverizers. MACARTNEY PATENTS, Ltd. Jan. 17, 1947, No. 1620. Convention date, Jan. 18, 1946. [Class 59] In an impact pulverizer, portions of the material to be pulverized are rotated about a common vertical axis so that under the action of centrifugal force two streams of material are formed, one of which is caused to move in a substantially horizontal plane and the other upwardly in a path intersecting the first stream to bring about a collision of the two streams. In the apparatus shown, material is fed from a hopper 56 to the apex of a rotating inverted hollow cone 6 located within an inverted frusto-conical shell 18, open at its lower end, which is rotated at a lower speed in the opposite direction, the cone and shell defining a grinding chamber 17 which is closed at the top by a plate 23 secured to the shell and formed with apertures 61, 66 communicating with a collecting chamber 51 fitted with a delivery outlet 57 containing a suction fan 58. The cone 6 is formed with a lip 14 so that a lining of material is retained to minimize wear, and its edge 16 is so shaped that the material is flung outwardly and substantially horizontally against the wall of the portion 21 of the shell. The latter is formed with a flange 22 to retain a lining of material in the shell, and particles of material from this lining are urged upwardly by centrifugal force assisted by the draught created by the fan 58 and impeller vanes 59 formed on the cone so as to flow in a stream intersecting the horizontal stream of particles flung outwardly from the cone. Pulverization thus takes place partially by impact with the wall 21 and partially by collision between the streams of particles. Each aperture 61 is surrounded by flanges 63, having a higher leading edge than trailing edge so as to create a lift, and is covered by an inclined sieve 62. The apertures 66 may be opened or closed by a movable plate 67, and when these apertures are open the apertures 61 may be blanked off. The shell 18 is located and guided by rollers and is driven by a pinion 38 meshing with a ring gear 37. In a modification, Fig. 6 (not shown), suitable for grinding wet material, the top of the grinding chamber is completely closed, and delivery apertures fitted with sieves are formed in the wall of the shell below the level of the top of the cone. The impellers on the cone are omitted.
