Abstract: 915,358. Packaging-machines. FMC CORPORATION. April 24, 1961 [April 28, 1960], No. 14699/61. Class 94(1). A machine for forming batches of containers and loading them into cartons by means of a reciprocating pusher having short and long strokes, the latter for thrusting a batch into a carton, is controlled automatically by pneumatic means including air pressure relief valves operated by the containers and cartons. Containers C, fed by a conveyer 11 on to a platform 12 operate through a lever 81a bleed valve B5 which causes the pusher 14 to make a short stroke, in which a roller 14a engages a valve B4 to initiate its return. After two short strokes, the containers contact a lever 87 operating a slide valve B5 which renders inoperative the valve B4 so that the pusher makes a long stroke to sweep six containers into a carton. Empty cartons are placed on a support 19, originally vertical. A carton flap F operates a bleed valve B1 by engaging a lever 55 whereby the support is pivoted to the horizontal position. In this position a bleeder valve B3 is operated so that the long stroke may take place. During this stroke, bleeder valves B6-B8 are engaged to restore the pneumatic system to the starting condition. The machine may be adjusted for various sizes and numbers of containers by altering the position of the valves and contacts.

Abstract: 196,203. Wriedt, F., and Milo Machinery Co. Proprietary, Ltd. May 29, 1922. Stationary drum and internal centrifugal crushing- blocks; roller - and - ring mills; disc and like mills.- A grinding or crushing mill for granular materials comprises a stationary cylindrical surface, one or more series of grinding- elements movable over the surface, means for facilitating the entry of material between the grinding-elements and the cylindrical surface, and means on the surface of the grinding-elements for displacing the material transversely to the direction of motion of the grinding-elements and from one end of the cylindrical surface to the other. As shown in Figs. 1 and 2, the grinding pads or shoes 22 are pivoted upon pins 21 fixed in spiders 20 carried by the shaft 15, and are pressed against the inside of the casing 10 by springs 23 secured to pins 24 on the spiders. The leading portions of the pads 22 are chamfered or bevelled to form spaces 25 into which the material can readily enter, and grooves or channels 26 may be formed in the chamfered portions of the pads. The grooves are preferably set obliquely to the leading edges of the pads so as to move the material transversely to the direction of motion of the pads. Fig. 5 shows a pad 22 formed with tapered grooves 27 instead of having its leading edge chamfered. The pads are arranged in series in parallel planes, and the pads of each series are positioned opposite to the spaces between adjacent pads of each adjoining series, and preferably the ends of each pad of a series project into the spaces between the pads in the adjoining scries. The grooves 26, 27 can be varied in form and extent in the different series. The material passes from a hopper 30 carried by the end-cover 11 into a supply chamber 31, whence it is fed into the pulverizing-chamber by oblique or helical vanes 32 on the shaft 15. The material may undergo a preliminary crushing between discs 33, 34 which are dished on their sides and provided with radial bars or ribs, the disc 33 being secured to the cover 11 and the disc 34 to the shaft 15. Thrust bearings 19 are provided for the shaft 15, and the distance between the discs 33, 34 is regulated by means of nuts 35 on the ends of the shaft 15. The crushed material is delivered through an outlet 28 in the cover 12 into a delivery shoot 29. Tapered or conical rollers 38, Fig. 7, may be used instead of, or in addition to, the pads 22. The rollers are rotatably mounted on arms 39 pivoted on collars 40 fixed to the shaft 15, and are pressed against the casing 10 by springs 23. The rollers may be arranged in line with, or obliquely to, the axis of the pulverising-chamber.

Abstract: 514,978. Iron. SACHTLEBEN AKT.-GES. FUR BERGBAU UND CHEMISCHE INDUSTRIE. May 20, 1938, No. 15166. Convention date, July 16, 1937. [Class 72] In the production of low carbon iron, iron ore is reduced with solid reducing agents in a rotary drum or tube furnace in which the charge is heated until the iron is molten so as to produce a pig iron containing 3 per cent. and over (e.g. 4-4.8 per cent.) of carbon, less than 0.2, and preferably below 0.1, of phosphorus and silicon and then blowing said pig iron in a sideblow acid or basic converter. The iron ore may be heated by means of pulverized coal burners arranged to function with an inert or a slightly reducing flame. Low-carbon iron obtained by this process may be mixed with high-carbon iron produced in the rotary furnace and adjusting the carbon content to that desired. In an example, a pig iron containing 5.10 of C., 0.031 of P., 0.015 of Si, 0.01 of S and 0.3 of Mn was produced in a rotary furnace and was cast into ingots which were melted in a cupola. 1,500 kg. of molten iron was then blown for 10 minutes in a basic converter with an addition of 25 kg. of quicklime and the product containing 0.1 of carbon C, 0.006 S, 0.03 P, 0.03 Mn and 0.02 Si.

Abstract: 583,203. Reciprocating pumps. TURNER MANUFACTURING CO., Ltd., and GROVES, W.R. Aug. 9, 1944, No. 15172. [Class 102 (i)] A revolving radial-cylinder reciprocating pump comprises a rotor 6 in which are mounted pistons 15 connected by pins 16 to shoes 17 bearing on an eccentric race 12 that loosely engages a bolt 33 passing through the housing and pivots on a knife edge 36. The race 12 is connected by a rod 35 to an abutment 44 for springs 46, 48 arranged within a housing 41 arranged tangentially to the pump housing 3. The springs 46, 48 hear against an abutment 45 guided by splines in a cap 50 and threaded on a spindle 51 so that spring pressure on the abutment 44 urging the pump to minimum output can be adjusted by the handwheel 56. The pump delivery is connected to the underside of the piston 43 to reduce the output as the delivery pressure rises. The driving shaft 5 is provided With a collar 20 that is slotted to engaged projections 22 on rotor 6 to transmit the drive. A valve 10a is secured to the end cap 1 and projects into the rotor 6 that is fitted with a steel sleeve 13 coated with cadmium or tin to provide a bearing surface. Suction takes place through the pump inlet 32, around the coupling collar 20, bores 25 and 26 in the valve to the port 27 cooperating with the cylinders. Delivery takes place through the port 28 and bore 29 in the valve. The inlet 32 is fitted with a scoop 57 having an opening 60 in a part of its circumference so that when the pump is idling the rotation of the slippers tends to force the liquid in the casing back into the inlet and therefore tends to create a surge to promote cooling of the ports.
