Abstract: 1,213,606. Moulding magnets. MAGNETFABRIK BONN G.m.b.H. 10 March, 1969 [19 March, 1968], No. 12545/69. Heading B5A. [Also in Division H1] A permanent magnet is moulded by feeding magnetic powder from a hopper 9 into a mould cavity 5, producing a magnetic field in the cavity by an electromagnet 6 energized with D.C. and compressing the powder during such energization by a punch 8. The electromagnet is de-energized during lateral movement of the hopper towards the cavity filling position, and an electromagnet 12 at the front of the hopper is supplied with A.C. during such movement to demagnetize that area surrounding the cavity to allow free powder flow. The cavity is formed between a die 2, core 3, and a lower punch 4 which is raised to discharge the moulded magnet which is then moved laterally by the front of the hopper. The powder may include a binding agent.

Abstract: 1,226,982. Constant-tension pipe support. PIPE SUPPORTS Ltd. 30 May, 1969 [4 June, 1968], No. 26378/68. Heading F2S. In a constant tension lever-type pipe support, the spring 15 acts on the lever 31 through one or more links 38, 39, the position(s) of which relative to the lever may be adjusted to alter the spring lever arm for different loads. The lever 31 is pivoted to a bracket 11 at the fulcrum 32 of the system. The load (i.e. the pipe) is connected to the lever 31 by an eye-bolt 51, and tends to rotate it in an anticlockwise direction. The spring 15 is mounted on the bracket 11 by a pivoted block 20, and acts on the lever 31 through a draw-bar 25. One end of the draw-bar 25 is fastened to the spring retaining plate 16 and the other end is pivotally connected by a chain link 39 to the link 38. Thus the spring tends to rotate the lever clockwise. Adjustment of the spring lever arm (i.e. the perpendicular distance from the line of application of the spring to the pivot 32) is effected by a screw 43 acting on the link 38, and thus adjusting the line of application of the spring force in the range (66, 67). The load lever arm can also be varied, by moving a pin 54 in a slot 60. In the support of Fig. 2 (not shown) the spring (72) is arranged to act in a generally vertical direction, and there is only one link (87) interconnecting the draw bar (79) and the lever (83). Adjustment of the spring lever arm is effected by a pin (91) having a flange (94) which co-operates with an indicator scale (95).

Abstract: 1,239,063. Electric selectors. GENERAL ELECTRIC CO. Ltd. 6 Nov., 1969 [8 Nov., 1968], No. 53060/68. Heading H1L. The crossbar switch generally described in Specification 1,216,186 is modified by making the interposers of magnetic material instead of nylon whereby repeated movements of a select bar do not strain the coupling between the bar and an operated interposer since this coupling is now only magnetic and not mechanical. In Fig. 1 the interposers 205 consist of hollow ferromagnetic boxes which normally rest on magnetized portions of the select bars 208. Operation of a select magnet 193 (in fact two such magnets since the switch provides a 10 x 30 matrix with level switching) causes the associated bar 208 and interposers 205 to move longitudinally below a set of combs 4 whereupon operation of a bridge magnet 183 causes an interposer to lift the required comb so as to close the selected cross point. The bridge magnet holds the crosspoint on, the select magnet being released so as to restore the select bar 208. At the end of the call the bridge magnet is turned off and the interposer returns to its home position by magnetic attraction. Either (but not both) the interposer or the bar portions may be magnetized. The portions may be permanent magnets embedded in a non-magnetic bar or magnetized stripes of a magnetic bar. Mechanical stops for the interposers may be provided on the bar. If the interposers are of dumb-bell shape, the neck, of the dumb-bell maybe trapped in a slot in the bar thereby providing a mechanical stop without hindering the essentially magnetic coupling.

Abstract: 1,251,100. Extruding; billet piercing. SCHLOEMANN A.G. 27 Nov., 1969, No. 58115/69. Headings B3H and B3P. A tube forming press comprises a movable mandrel crosshead 7, 8, 9 carrying a rotatable nut 19 for adjusting the position of a screw threaded spindle 16 connected to a mandrel holder 15 and a coupling member 25 which is movable in a longitudinal direction between one position in which it couples with the nut 19 so as to allow rotation of the spindle 16 and another position in which it couples with the mandrel crosshead so as to allow longitudinal movement of the spindle 16. A billet is pierced by moving the mandrel crosshead 7, 8, 9 and attached mandrel 18 by a piston and cylinder device 5, 6. After the billet has been pierced, the tube is extruded by a hollow ram 4 which is attached to a crosshead 3 moved by a ram 2. The movement of the mandrel crosshead 7, 8, 9 during extrusion is prevented by bayonet members (41) (Fig. 2, not shown) fixed to the press engaging hollow bayonet members (42) on the crosshead 7, 8, 9, the members (42) having been moved into an abutment position by a lever (43) (Fig. 3, not shown). The ram crosshead 3 and mandrel crosshead 7, 8, 9 are retracted by piston and cylinder devices (47, 48) and (35, 37) respectively. If a different size mandrel 18 is to be used, the spindle 16 and attached mandrel holder 15 are moved longitudinally by rotating the nut 19 by a worm 22. The spindle 16 is prevented from rotating by a spline connection 30 between it and a sleeve 29 integral with the coupling member 25 which is connected to the mandrel crosshead 7, 8, 9 by a dog connection 26, 27. The mandrel 18 may be rotated when non-circular tubes are to be extruded by moving the coupling member 25 to the left so that dogs 24 thereon engage dogs 23 on a sleeve 20 which is attached to the nut 19. When the nut 19 rotates the spindle 16 and mandrel holder 15 are also rotated.

Abstract: 1,251,269. Valley tiles. REDLAND TILES Ltd. 26 May, 1970 [23 May, 1969], No. 26493/ 69. Heading E1B. A concrete valley tile 11 has along either side of its upper concave surface a mortar retaining ridge 15 and a plurality of mortar holding ribs 21. The next overlying tile up the valley is adapted to rest on projections 16 which project slightly further than a ridge 17 which acts as a barrier to wind blown water but is spaced from the tile above so that no path for capilliary flow exists. The tiles of the side surfaces meeting at the valley rest on the plane surfaces provided by ribs 14 and 15 which define a water drainage channel therebetween.  (For Figure see next column)
