Filed: 1963-06-14
Abstract: 1,041,373. Electrically tripped switches. TELEMECANIQUE ELECTRIQUE. June 14, 1963 [June 15, 1962], No. 23865/63. Heading H2B. An overload relay comprises a bimetal 5 connected in parallel with a conducting rod 6 surrounded by a conducting ferromagnetic mass 7. On overload the bimetal is heated, both directly by the current through it and indirectly by the mass 7 heated by currents induced in it, and bends, tilting a bar 20, common to several phases, to release a latch 22 and open contacts 23, 24. The mass 7 is also shaped to form poles 37, 38 (Figs. 1, 3, not shown), which attract a pivoted armature 33 to slide the bar 20 against a spring loading 28 and thus release the latch 22 instantaneously on heavy overload. The contacts are reclosed by depressing and then releasing a push-button 40 (Figs. 4, 5, not shown). The sensitivity of the relay can be altered by exchanging the rod 6 for one of a metal of different conductivity (e.g. steel, brass, copper) thus changing the portion of the current passing through the bimetal.

Title: Improvements in and relating to gun turrets
IPC: F41A27/06
Filed: 1944-12-01
Abstract: 587,026. Turret guns. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. Dec. 1, 1944, No. 23979. [Class 92 (i)] A rotatable gun turret of the kind in which the gunner is accommodated between two guns or two groups of guns capable of elevation and depression relative to a plane parallel to the plane of rotation of the turret, is provided with means for sliding the guns to the rear when depressed and forwardly when elevated so as to reduce the obstruction by the guns of the gunner's view to the sides. In the construction shown, the gun cradle 2 pivots on a slide 3 movable in guideways 5 and carries a slotted quadrant 7 whose slot 8 engages with a pin 9 fixed to the turret structure. The slot 8 is eccentric with respect to the pivot on slide 3 with the result that the pivot moves relatively to the fixed seat 6 when the gun is elevated as at A or depressed as at B. In a modification, Fig. 2 (not shown), the gun is elevated and depressed by a hydraulically controlled plunger, the fluid supply source for which is connected also to a cylinder housing another plunger which is connected to the slide 3, thus imparting to the slide the appropriate forward and backward movements when the gun is elevated and depressed. The Provisional Specification which refers to the mounting of the guns on aircraft also states that the relative movement between the guns and gunner's seat may be effected by causing the gunner's seat to move when the guns are elevated or depressed.

Title: Improvements in or relating to process for concentrating an ore
Inventor: LAWVER JAMES E
IPC: B03C7/00
Filed: 1952-09-30
Abstract: Ores containing non-silicate minerals are concentrated by an elecrostatic process, the ores having been comminuted to liberate desired components from gangue, dried, heated to between 105 DEG  and 550 DEG  F. and contacted while in this temperature range with a source of electrons, e.g. a grounded conductor of carbon, aluminium, zinc or brass.  In the treatment of silica-containing phosphatic ore the ground ore may be sized into coarse and fine fractions, e.g. a fraction between 14 and 325 mesh and a fraction less than 325 mesh. The coarse fraction is treated according to the invention to yield a concentrate, a silica-containing middling and a tailing, the middling being recycled through the treatment.  The taining may also be subjected separately to a further concentration treatment.  The concentrates obtained from these separate treatments may then be combined with the originally obtained concentrate.  Sylvinite may be treated, being crushed, dried, separated into a coarse fraction between 24 and 200 mesh and a fine fraction less than 200 mesh, the coarse fraction being heated to 180 DEG -380 DEG F., contacted with the source of electrons and separated electrostatically into concentrate, middling and tailing, the last two being separately and similarly treated to obtain further concentrates.
