    Abstract: In the fractional crystallization process such as are described in Figs. 6-8 (not shown) wherein the crystals are separated out in each stage by means of a trough similar to that of Fig. 1. The crystals are melted and at least partially returned to a preceding stage. The fused mixture is contained in trough 1 while internally cooled disc becomes coated with crystal layer 4 which is melted in device 5 and the purified melt is withdrawn through pipe 6. The heating and cooling of the disc may be by electric means or by using hollow constructions with heat exchange liquids.

The condensate discharger disclosed in the parent Specification, is modified by forming a plurality of equisized and spaced holes in the valve plate, in the neighbourhood of the valve sealing surface, to reduce vibration of the valve caused by discharging very small quantities of condensate.

    Abstract: 1,087,432. Slitting apparatus. BADISCHE ANILIN- & SODA-FABRIK A.G. Jan. 15, 1965 [Jan. 18, 1964], No. 1817/65. Heading B4B. Apparatus for slitting a plastics sheet wound on a spool 55, Fig. 1, into a number of strips, e.g. as recording tape, which is drawn off on to take-up spools 119 comprises a cutter head 52 in which cutters 51, Fig. 2, e.g. razor blades, are clamped together between plates 29 ... 31, Fig. 6, the head being secured to a swinging arm 60 and driven by a motor via an eccentric and connecting rod. A co-operating grooved roller 53 is mounted in bearings on an eccentrically displaced shaft 39 secured on a swinging arm 2, so that it may move backwards and forwards in an arc, and is swung in, by a lever 44, for cutting to commence. A lever 7 effects the cutting movement of the grooved roller, and a lever 12 the swinging movement of the cutter 54 head, the levers being controlled by a disc 14 carrying push-rods 15, 16 in a double eccentric arrangement, driven by a pulley 21. The oscillations of the grooved roller are 90 degrees out of phase with those of the cutter head, so that the cutters in operation move in an endless curve in continuous relative movement with respect to the sheet being slit, so that the point of cutting on the cutting edge is continuously being changed. The take-up apparatus for the spools 119 comprises a hollow shaft 121, Fig. 5, and a main shaft 101 arranged so that when the thickness of the tape to be severed is constant the shafts run at the same speed, but may be compensated for different thicknesses of tape by changing the speed. Both shafts are driven by a pulley 101 via clutches 108a, 108b by belt drive from a variable-speed motor. Up to four tapes may be wound simultaneously on each shaft. The tape is cleaned before being wound up, by duster rollers, blowing or suction.
