A process for enamelling a metallic workpiece, e.g. a cast iron bath-tub, comprises conveying the workpiece from a supply station 1 to a loading station 2 by first conveying means, loading the workpiece on to a second conveying means 3 which conveys the workpiece through a first furnace 5, wherein the workpiece is heated to, e.g. 920‹ C., transferring the workpiece to a third conveying means at 6 and conveying to an enamelling station 9, where an enamel coating, preferably as powder, is applied to the workpiece, conveying, on fourth means 10, the workpiece to a second furnace 11 (preferably at 930‹ C.) for firing, and subsequently removing from furnace 11 for cooling. The second conveying means, which may comprise individual carriages, may move in a closed circuit from 2 through tunnel furnace 5 and back to 2 via return line 8. Preferably, the carriages are pushed by those following. Preferably, only a single door is provided in furnace 11. At the enamelling station 9 (Fig. 10, not shown), the workpiece is so supported that a " planetary " type of double rotation is imparted to the workpiece, while enamel powder is dredged over the workpiece through a screen. The temperature at the enamelling station may be 850-920‹ C. The upper edges (of the bath-tub) may be enamelled by hand. The workpiece may be coated with an enamel slip before heating in the first furnace.

Abstract: 953,314. Fuel injection pumps. LEYLAND MOTORS Ltd. March 24, 1960 [Dec. 29, 1958], No. 41928/58. Heading F1A. A fuel injection pump plunger 6 is hollow and has a valve 7 which seats on the head thereof. The plunger 6 carries a cam 11 engageable with rollers 12 on a member 13 the angular position of which is adjustable by means of a rack 15. The cam 11 is clutched to a further cam 17, engageable with rollers 18 on a fixed or angularly adjustable member 19, and connected through a flexible coupling to a drive shaft 24. A spring 27 holds the valve 7 in engagement with cam 17 and the plunger 6 in engagement with the valve 7. The arrangement is such that the cam 17 lifts the valve and plunger until the cam 11 engages the rollers 12 which stop further rise, or even cause a return movement, of the piston, whereby the valve 7 and plunger 6 separate and discharge is halted abruptly. The rack 15 alters the point of discharge and hence the output; adjustment of the member 19 alters the timing. The plunger 6 rotates and distributes fuel from the enlarged chamber 5 via a slot 9 to outlets 3. In a modification the pump has an outlet valve which feeds the discharge to a groove in the cylinder base which communicates with a slot in the piston for distributing to outlets; the cam 11 is axially adjustable by means of the rack 15 operating a screw and nut mechanism. The casing 1 is kept filled by a low pressure pump.

Crystals are obtained from a slightly supersaturated, aqueous solution of a salt by introducing the solution, at a temperature of 81 ‹C., through pipe 19 into an apparatus comprising two columns 1 and 3 connected to form a continuous circuit, and injecting liquid cyclohexane at 68‹C. through perforated ring 17 into column 1. The cyclohexane ascends rapidly through the solution, and vapours of the cyclohexane/water azeotrope at 69‹C. are formed. The salt solution cools to about 71 ‹C. with simultaneous separation of crystals of salt. The bubbles of vapour cause circulation of the solution through the apparatus; and the larger salt crystals are deposited in grading device 4. Vertical plates 18 ensure good dispersion of the bubbles of cyclohexane in the aqueous solution. The azeotrope vapours pass through chamber 2 and pipe 6 into mixing condenser, which is supplied with cooling water through pipe 8. The condensate and water flow into decanter 10, from which the separated cyclohexane is returned via pipes 11 and 12 to injector 17. The bottom of decanter 10 is provided with a conduit 13 leading to valve 14 controlled by level-regulator 15 for controlling the discharge of water from the decanter. An auxiliary fluid may also be applied to the separation of crystals from a saturated aqueous syrup of an organic compound; but in this case vapours of m-xylene are injected into the syrup contained in the circulation apparatus.
