To remove a contact, split tool 60 is slipped along the cable to dilate the collet. After all contacts have been inserted, cover 56 is screwed into the rear of the metal shell 10 round each pair of inserts and a cable clamp (not shown) is fitted. Alternative designs include a contact with parallel waist or with a retention collar instead of a waist: the contact may carry lugs to fit behind the collet to prevent forward movement, in which case tool 60 is slotted to pass the lugs.

[Also in Division F2] A tape cassette contains a drive roller 27 having an axial cavity adapted to be frictionally engaged by a driving shaft 37 having a smaller diameter than that of the cavity. The cavity and/or shaft are preferably lined with elastomeric material 38. As shown, an endless magnetic tape 3 is guided from a storage 8 to an operational compartment 9 where it is pressed against a fixed guide cylinder 12 by a braking pad 13 mounted for pivoting movement about axes 15, 16 and 21 before passing over head 74 then a roller 27 co-operating with a pressure roller 29 mounted for limited rocking movement about an axis perpendicular to pin 32, to feed the tape.

Abstract: 1,188,680. Refining molten metal. KAYSER INDUSTRIES CORP. Nov.22, 1967 [Nov. 25, 1966], No.53250/67. Heading C7D. Molten metal, particularly steel, is deoxidized in a furnace chamber by passing a H 2  - containing atmosphere into contact with the metal surface to react with the O 2  in the metal to form water vapour, and stripping water vapour from the atmosphere, e. g. by circulating over water-cooled condensing coils at the chamber walls or through gettering or stripping columns, to maintain the volume percentage ratio of H 2  O:H 2  in the atmosphere not more than 0À14. When the O 2  content of the molten metal is reduced to the desired level, the H 2  content of the atmosphere may be lowered to not more than 4% by volume and the water vapour content lowered to not more than 0À1% by volume to reduce the H 2  content of the metal to not more than 0À0005% by weight. A metallic deoxidizer such as Al may be passed below the metal surface to complete deoxidation. The atmosphere may be pure H 2  or a gas mixture of H 2  and an innocuous gas such as an inert gas, CO and CO 2  or steam and partly burned natural gas. The melting furnace may be induction heated.
