Title: Electrical contacts for fuseholders
IPC: H01R13/68
Filed: 1979-02-27
Abstract: A panel mounting electrical fuseholder for cartridge fuse elements has an electrical contact (4) comprising a first annular portion (7) a second portion (8) which extends, substantially perpendicular to the plane of the annulus, outside the body (1) of the fuseholder and a third portion (9) which extends substantially perpendicular to the plane of the annulus on the same side of the plane as the second portion (8). The second portion (8) has a projecting tongue (10) which engages behind a shoulder (11) on the fuseholder body (1) to retain the contact (4) in the fuseholder. 
<??>The third portion (9) resists the tendancy of the contact (4) to tip and become dislodged when the terminal portion (12) of the contact is bent away from the body (1) to facilitate soldering of a lead to the terminal portion (12). A skirt (17) is provided on the body (1) to prevent release of the latching tongue (10) from the shoulder (11) without the use of a tool.
Patent GB-2016986-A (GB)
Title: Method of arc welding
IPC: B23K9/167
Filed: 1979-04-06
Abstract: There is disclosed a method of all-position welding a full penetration, root or complete, weld bead between components (particularly tubular), without the use of filler metal, by traversing a non-consumable electrode, e.g. thoriated tungsten, over the components. A direct arc current which is pulsed is used. The shielding gas is helium or a mixture of two or more of the gases helium, hydrogen and argon in which helium is a major ingredient or in which hydrogen is a minor ingredient. The components at the butting weld faces have a thickness of no greater than 3 mm. Example component materials are stainless and carbon steels, titanium, nickel and nickel-copper alloys and aluminium bronze. The resultant weld bead 11 has a back face 12 which is flush with or slightly proud of the adjacent surfaces of the components instead of forming a shallow depression as can form when using prior methods for all positional welding. Welding of tubular components may be effected externally or internally. In external orbital welding, a gas backing, e.g. of helium, argon or a mixture thereof, may be provided. <IMAGE>

Patent GB-2078425-A (GB)
Title: Improvements in or relating to bells
IPC: G10K1/064
Filed: 1980-06-10
Abstract: A volume control for a bell, e.g. of a subscriber's telephone, consists of a pad 34 of friction material which is urged against a clapper rod 18 by a movable cam 40 to vary the amplitude of vibration of a clapper 19. The volume of the bell can thus be adjusted whilst both bell gongs remain operative if there two such bell gongs. The clapper rod may be relatively stiff, in which case the amplitude of vibration is controlled by the friction pad only, or the clapper rod may be flexible so that the clapper is lifted relative to conical bell gongs. In the latter case the distance between the bell gongs increases upwardly due to their shape and so little friction is required between the friction pad and the clapper rod. <IMAGE>
