Patent GB-1473095-A (GB)
IPC: B22D11/04
Filed: 1973-04-30
Abstract: 1473095 Continuous casting ALCAN RESEARCH & DEVELOPMENT Ltd 25 April 1974 [30 April 1973] 20553/73 Heading B3F At least the long side metal (Al or Cu) walls 5, of an open-ended mould for the production of rectangular (Al or alloy) ingots, or all the walls of such a mould for producing square or nearsquare ingots, may be varied in curvature by flexing each of them outwardly about an axis parallel to the casting direction, e.g. manually or automatically by means of a turnbuckle 16, yoke 15 and links 12 or by hydraulic, pneumatic, mechanical or electromechanical means, so that the flexing can be progressively increased with increase of casting rate. The four walls may form a unitary structure so that end walls move towards and away from each other as the result of flexing of the sides. The side walls may converge slightly towards the outlet end of the mould. The end walls, however, may be of usual rigid form and movable so that there may be cast ingots of different widths and (by employing end walls of different width) ingots of different thicknesses. By progressive inward or outward movement of the end walls, a tapered ingot may be cast. The upper parts of the mould may be lined with flexible sheet insulation as in Specification 1,026,399. If reduction of casting speed should become necessary, bowing of the walls may be reduced. The mould may be fed by a float-controlled pouring tube, but instead of being vertical, it may be horizontal or inclined. To provide the bowing out of the side walls necessary to counteract the greater metal shrinkage which during solidification occurs near the middle of the ingot wide faces, and yet avoid undesirable convexity of the ingot butt portion, the bowing is increased progressively as the ingot withdrawal speed is increased, i.e. as the speed of a lowering stool (1) is increased. The mould may be supported by a surrounding frame 4 also constituting a water header. Water jackets 7 support the mould side walls 5 and have orifices (23) to direct water down on to the backs of the walls 5. The end walls 6 are rigid water boxes having an outlet slit for spraying the emerging ingot; a hose 9 connects a wall to the header 4. Rollers 20 restrain the ends of the walls 5 against outward movement. A spray pipe (27) directs jets through orifices (28) on to the ingot.  In a modification, a side wall 101, Fig. 8, is backed by a flexible abs or pvc conduit 112 for cooling-water, to flex with the wall, and having a tengential fin forming an envelope at the back of the wall 101 to define a water jacket space in which the mould wall is sprayed with water. A gap (124) at the bottom allows the water to pass on to the emerging ingot. Where lugs 106, 107 provide connections for applying the bowing force, apertures 130 emit the ingot-cooling water and there is an adjustable baffle 131 for cooperation with the apertures. A duct 115 is for lubricant. In Fig. 10, the envelope defining the water jacket space 207 is formed by a neoprene &c. membrane 206 around the supply conduit 204.

Patent GB-1584641-A (GB)
Title: Frequency-modulated data communications receivers
IPC: H04L27/14
Filed: 1977-06-28
Abstract: This device is suitable for use under propagation conditions severely affected by interference, in particular in mobile stations, in which propagation delay differences occur at the receive location due to the alternate routing differences of the reflected carrier waves. The information losses caused by phase and amplitude distortion are thereby automatically identified according to their cause in two arrangements which complement one another, i.e. in an equaliser for dynamic cancellation and an equaliser for static cancellation. The equaliser for dynamic cancellation has a frequency discriminator (3) with a device connected downstream for noise peak detection (DE) and the equaliser for static cancellation (SE) has an amplitude demodulator (9) with a polarity inverter (11) connected downstream and controlled by a polarity integrator (12). Depending on the type of interference detected, one or the other equaliser is through-connected on the output side via a changeover switch (13) to the common output. <IMAGE>

Title: Improvements in clamping devices
IPC: E04G7/30
Filed: 1954-07-17
Abstract: 765,360. Clamp fastenings. CROWTHER, F. June 8, 1955 [July 17, 1954], No. 20884/54. Class 44. [Also in Group XV] A clamping device comprises an open-ended member forming part of one (4) of two members 4, 13 adapted to be clamped together, the openended member being in the form of a channel adapted to embrace the other (13) of the two members, a stirrup member adapted to engage an abutment in the channel, and screw means 10 co-operating with the stirrup member to cause clamping pressure to be applied to the member embraced by the channel. As shown, the channel-shaped member has parallel sides 1, 2 and a V-shaped base 3, and it is secured by welding to the member 4 which forms part of a structure, e.g. a physical training structure for children. Each of the sides has a rectangular aperture 5, 6, one wall of each of which forms the abutment and the stirrup member is U- shaped and has legs 7 and 8. The stirrup member is passed through the aperture 6 so that it is anchored to the side 2. The legs 7 and 8 are spaced by a distance piece 9 which has a tapped hole for the screw means 10 which engages a member 13. The leg 7 has a bentover end 11 for engagement with the outer surface of the side 1 after passing through the aperture 5, the bent-over end 11 preventing the sides of the channel opening under load. The distance piece 9 is spaced from the closed end of the stirrup member sufficiently far to allow the end 11 to be withdrawn from the aperture 5. In a modification, the base of the channel may be provided with a hinge so that any load is transferred directly to the bent end of the stirrup member. Instead of having two apertures in the channel, one side may be turned outwardly to form a hook and the stirrup member is formed with an aperture which engages the hook. The other end of the stirrup member has a projection adapted to pass through an aperture in the other side of the projection being hooked at its end if desired. The side 1 may be extended to form a foot 12 when the member 4 forms the lowermost member of the built-up structure. The Provisional Specification describes a modification in which the channel-shaped member has a plurality of serrations in one side, one of which is selectively engaged by the stirrup member which does not engage the other side. The stirrup member has a lug extending away from the base of the channel which is tapped to secure the screw means which exerts pressure on the inside of the serrated side to force the stirrup against the member 13 to clamp it in the channel.
