Patent GB-906010-A (GB)
Title: Methods of treating fusible materials by zone-melting
IPC: C30B13/00
Filed: 1959-02-23
Abstract: In a zone refining method a molten zone is moved simultaneously along solid material in each of at least two distinct traversal paths from one material transfer path to another, each transfer path connecting one end of one traversal path to the adjacent end of the other traversal path, while material being refined is fed into one end of each transfer path and removed from the other. More than one molten zone may be moved through each traversal path at the same time.  More than two traversal paths may be employed in parallel with adjacent or staggered transfer paths.  The traversal paths may be separated by infusible partitions, by maintaining portions of the material solid, or by staggering the moving molten zones.  The traversal paths may be rectilinear (Figs. 3 and 7) or arcuate (Fig. 9).  There may be one or more intermediate transfer paths.  The quantity of material in each of the two terminal feed streams may be 2% of that of material in a single intermediate feed stream.  The two terminal feed streams may be in the same or opposite direction.  The material may be fed <PICT:0906010/III/1> <PICT:0906010/III/2> <PICT:0906010/III/3> continuously or intermittently and may be solid or liquid.  It may be transferred from one traversal path to the next as a liquid by passage through a valved or unvalved orifice under gravity or by laddling or as a solid by means of a conveyer belt.  The ratio of volume transferred per unit time to volume traversed per unit time may be up to one or above, e.g. 0,01-0,5.  The refining may take place in a protective atmosphere or vacuum.  Resistance or induction heating may be employed.  Lead or naphthalene may be refined in an apparatus of stainless steel and germanium may be refined in an apparatus of graphite.  Specifications 769,673, 769,674, 786,170 and 786,171 are referred to.
Patent GB-589833-A (GB)
Title: Improvements in or relating to gramophones
IPC: G11B17/02
Filed: 1945-03-12
Abstract: 589,833. Automatic gramophones. INDUSTRIAKTIEBOLAGET LUXOR. March 12, 1945, No. 6115. Convention date, March 20, 1944. [Class 40 (ii)] In a gramophone provided with an automatic record-changing mechanism in which the traverse of the pick-up arm is controlled by a cam disc, and in which provision is also made to prolong at will the interval between successive playings, the traverse of the pick-up arm during the delay period is suspended by means of an alternative motion-action provided by the cam-disc. The drawing shows an underside view of the cam disc 1 and links 5 and 4 connected to a spindle 3 on which the pick-up arm rotates. During a normal record-changing operation the lever 12 rests in the position shown by chain-dotted lines. The cam disc 1 revolves counterclockwise, and the pin 8 eventually comes into contact with the inner edge of the lever 12, is moved towards the centre of the cam disc 1 and takes up such a position that the pick-up arm, when lowered by mechanism, not shown, enters the first groove of the record, after which the cam disc 1 comes to rest in the position shown. When the engagement of the pick-up with the record is to be delayed, the rod 18 is moved towards the centre of the cam disc 1 to the position shown by chain-dotted lines, so that when the cam disc 1 revolves, the lever 12 is urged to the position shown by full lines, owing to contact of the pin 14 with the sloping face 20. At each revolution of the cam disc 1 the pin 8 contacts the heel of the lever 12 and moves it back to the position shown by the chain-dotted lines, but the lever 12 is almost immediately returned to the fullline position, owing to further contact of the pin 14 with the sloping surface 20. As the pin 8 therefore receives no motion towards the centre of the cam disc 1, no traverse of the pickup arm will occur until the rod 18 is withdrawn.

[Class 39 (i)] An artificially cooled high-pressure mercury - vapour tube has a filling of a gas such as neon and a mercury vapour pressure greater than 6 atmospheres and is furnished with solid incandescent electrodes which protrude only slightly from a quantity of mercury or amalgam whichpartlysurrounds the electrodes. Cadmium or zinc may be added to the mercury in the form of an amalgam. The correct quantity of mercury may be added by furnishing a quantity of mercury in an auxiliary tube, for example, the exhaust tube, and sealing off the end of this tube so as to expel small quantities of mercury into the main tube whilst observing. the electrical characteristics. In one form, the leads 2 are sealed into the quartz bulb 1 by coatings 3 and caps 4 of the glass described in Specification 431,923. Thin tungsten wires 5 are wound on the ends of the tungsten wires 2 and the combined wires are then oxide-coated. Mercury 6 is added until the electrodes 5 protrude about 1.3 mms., and until the seals between the caps 4 and the tube 1 are covered. In a modification for ultraviolet light production, the quartz tube is narrowed adjacent the electrodes. The mercury pressure in operation is between 6 and 32 atmospheres, for example, 20 atmospheres. The invention is applicable to tubes of the kind described in Specification 431,923.
