Title: Method and apparatus for the treatment of refuse for conversion into fertilizers
IPC: C05F17/02
Filed: 1963-03-15
Abstract: <PICT:0963804/C1/1> Refuse is passed continuously to a rotary crusher and ejected tangentially in countercurrent to a stream of air, thereby being separated into heavy non-fermentable material (pieces of glass, earthenware, &c.) and light fermentable material.  The fermentable material is allowed to ferment for a period and is then recycled to the rotary crusher with further refuse.  The refuse may be moistened with water in the crusher or before or after passage thereto.  As shown, iron, paper and bottles are first removed from refuse on a sorting belt 2 and conveyed away by belts 4, 5 and 6. The remaining refuse is conveyed to a pit 7 in a bunker 11 and then conveyed by an elevator 8 to a swing hammer crusher 9 and ejected at a desired angle by a guide plate 10 in countercurrent to a stream of air (not shown).  The stream of air may be produced by a blower which draws air in at sorting belt 2 and emits near the rear end of bunker 11. The air may be withdrawn from bunker 11 through a cyclone for the removal of entrained particles.  The heavy material is projected to a catch plate 12 and passed out of bunker 11, while the fermentable material falls on to a slowly moving bed of fermenting material on a plate conveyer 13.  The fermenting material passes to pit 7 and thence is returned to crusher 9 together with fresh refuse.  After sufficient build-up of fermenting material, bunker 11 is emptied by interposing a catch plate 17 between plates 10 and 12 and deflecting the material to a conveyer belt 18.

Abstract: 1286702 Tool-changing apparatus; multispindle drilling machines VERO NC DEVELOPMENTS Ltd 1 June 1971 [4 March 1970] 10476/70 Headings B3B and B3C A drilling machine comprises a hollow spindle 10 (Fig. 1) having a drill-retaining collet 18 at its forward end, a motor 13 for rotating the spindle, a magazine 21 (Fig. 2) arranged to feed drills 20 in succession to a loading station opposite the rear end of the spindle, a reciprocable plunger 30 aligned with the loading station, and means for actuating the plunger to cause it to move into the spindle from the rear end thereof to eject a used drill from the collet and place a new drill therein. In operation, each new drill may assist in ejection of the old drills, or, alternatively, the plunger may execute alternate longer ejection strokes and shorter insertion strokes. However, in the preferred embodiment, as shown, the plunger executes strokes of equal length, and blanks 22 alternate with new drills 20 in the magazine. The blanks have a diameter smaller than that of the collet so that they fall freely therethrough to eject the old drills. The machine embodies a number of such spindles, each with its individual drive motor and tool-changing gear. Each spindle 10 together with its motor 13 can undergo vertical feed motions along columns 16. A shoe 17, which is spring-loaded, acts to press the workpiece, such as a printed circuit board 11, against table 12. The latter is traversed clear of the spindle nose prior to tool change, and a collector placed there instead. The motor 13, normally driven by A.C., can be injected with D.C. to brake it quickly prior to tool changing. Plunger 30 is pneumatically reciprocated under the control of a solenoid-operated valve. Drills 20 and blanks 22 are urged into alignment with plunger 30 by a pair of springs 25 acting on a stirrup 27 which bears upon a bar 26. A spring-urged pin 33 retains each drill or blank at the loading station until the plunger is moved. Each new drill is retained by an 0-ring 19- until the motor 13 rotates the spindle whereupon the collet grips the drill centrifugally. The magazine may be movable and arranged to present new drills under tape control.

Abstract: 946,293. Brazing; abrasive tools. CINTRIDE Ltd. April 1, 1960 [April 1, 1959], No. 10961/59. Headings B3D and B3R. In brazing an abrasive material to a metal base a brazing medium, a liquid holding medium and an abrasive material are applied to the base to be coexistent thereon, at least some of the brazing medium being so applied as to form before and on fusion or diffusion at least a part coating over or on the upper surface of the abrasive material away from the base and the holding medium being such as to be effective during brazing and until the brazing medium is capable of retaining the abrasive in position. In making an abrasive disc a paint like mixture of copper in polymethacrylic ester, xylol and propyl glycol is sprayed on one or both sides of a mild steel disc, tungsten carbide or cobalt alloy granules are sprayed thereon and a coating of the paint like mixture is applied over the abrasive. The disc is heated to 1150‹ C. in hydrogen to vaporize the adhesive and melt the copper. An abrasive file with the tungsten carbide grit on one side possibly of different size from that on the other is similarly produced. An abrasive carbon steel sheet is made by spraying the sheet with gum resin or shellac and then with copper coated tungsten carbide grit, the assembly being heated in a protective atmosphere to effect brazing. A continued holding and brazing medium may be sprayed over the grit before heating. In another embodiment a carbon steel disc is sprayed with, in order, gum resin, copper powder, gum resin, tungsten carbide grit and gum resin and copper separately or mixed and the dried disc is heated in a furnace. A carbon steel slitting disc is produced by spraying the disc with a mixture of gum resin, copper powder and tungsten carbide, the mixture being such that at least most of the tungsten carbide is covered by resin and copper and the dried disc is heated to effect brazing. The materials may be applied by brushing, dipping, sprinkling or rolling, the abrasives may be carbides, oxides, nitrides or silicides of tungsten, tantalum, titanium, niobium, aluminium, chromium, vanadium, molybdenum or boron with or without bonding metals cobalt, nickel or iron and the brazing medium may be nickel, brass or iron.
