Abstract: 1,203,351. Continuous casting machine PROLINZENZ A.G. 22 Aug., 1968 [7 Sept., 1967], No. 40244/68. Heading B3F. In a continuous casting machine of the type having a mould cavity defined by a co-operating pair of endless sets of mould blocks which are driven at the same speed so that over a portion of their run they engage with each other and define between them a moving mould cavity, the rear surfaces of the mould blocks 10 are connected to but spaced from a guide member 11  by supporting means constructed so that the blocks 10 are thermally insulated from the member 11 to the extent that the heat conductance from the casting wall to the rear surface of the blocks is at least 200 times the conductance of the path provided by the supporting means between the rear surface and the member 11. The mould blocks 10 are fastened to the guide member 11 by a steel bolt 15 which is pulled against the member 11 by means of a nut 16 with interposed cup springs 17, and are spaced from the member 11 by steel bolts 12 which have rounded ends and rest on hardened steel backings 13. Guide pieces 21, (22) and (23) fixed to the member 11 are slidably received in grooves 18, [19) and (20) in the block 10 and maintain a fixed point H of each block in a fixed position relative to the guide member 11 whilst allowing expansion and contraction of the block. The thickness of the mould blocks 10 is such that the rear portions of the blocks remain cool and thus restrain the casting wall from appreciable expansion or contraction. A reflective metal sheet 24 is arranged between each mould block and guide member. In another embodiment, Fig. 10 (not shown), the mould blocks are made from a number of plates (44) held together by tie rods (45). The plates may be made of different materials e.g. steel and copper, and may be spaced from each other by layers of heat-resistant material.

Abstract: 1,072,819. Transistor pulse circuits. SOCIETE INDUSTRIELLE BULL-GENERAL ELECTRIC. Sept. 21, 1965 [Oet. 19, 1964,], No. 40265/65. Heading H3T. In a circuit for detecting slowly rising signals such as asynchronous data pulses from a slow store, the signals are gated to an. integrator by clock pulses having a repetition period much less than the rise time and the output of the integrator sets a bi-stable circuit when the signal amplitude exceeds a given level. In Fig. 1, terminal E1 receives positive-going signal pulses (waveform E1, Fig. 3, not shown), and terminal E2 receives the clock pulses (waveform E2). These terminals are connected to an AND gate D1, D2 so that during clock pulses an integrating capacitor charges to an extent dependent upon the amplitude which the signal pulse has reached allowing the potential at point A to rise (waveform A). At the end of the clock pulse point B goes negative by an amount dependent upon the charge (waveform B) and if this is sufficient, transistor T is cut off. Accordingly a bi-stable tunnel diode circuit DT is switched to its high voltage state causing T2 to conduct and T3 to be cut off (waveform F). This allows clock pulses to be passed through a gate diode D4 (waveform S1). When one of the clock pulses has been used coincident pulses are applied to the input of a transistor gate (Fig. 4, not shown) to earth point 17 so as to restore the tunnel diode to its low voltage state and thus terminate the output pulse train. In an alternative circuit (Fig. 2, not shown) the tunnel diode (DT) is normally in its high voltage state and is controlled directly by the input gate D1, D2 and integrating circuit R1, C2, transistor T1 being omitted.

Abstract: 1,218,909. Electron microscopes. COMPAGNIE D'APPLICATIONS MECANIQUES A L'ELECTRONIQUE AU CINEMA ET A L'ATOMISTIQUE. 14 Aug., 1969 [14 Aug., 1968], No. 40722/69. Heading H1D. A device for adjusting and changing the specimen, in e.g. an electron microscope, comprises a first mechanism 3, 5 for imparting movement to the stage 1 of the microscope within two degrees of freedom and for removing the stage to a position opposite the aperture of an air-lock chamber 30, and a second (ejection) mechanism 20 for translating the stage 1 to a position (Fig. 2) where it obturates this aperture. The microscope shown comprises a gun 53 and an electron-optical system 54 for focusing secondary ions from a specimen E along an axis y-y (Fig. 1). For adjustment of the position of the specimen whilst under examination (Fig. 1), the stage 1 is supported by a rod 5 slidable within a rocking cradle 3 which together determine its angular position about an axis 4 and its distance from this axis. The cradle 3 is also capable of rotating the stage 1 to a second position (Fig. 2) where the sliding stem 55 of the stage lies opposite an ejecting rod 20. This rod urges the stage 1 into a position in which it seals the chamber 30 and ejects the specimen E into the chamber. The vacuum in chamber 30 may be released by opening valves 13 and 41. Angular and linear movements of the stage 1 whilst in the operative (Fig. 1) position are respectively controlled by motors M## and M#R, the first of which actuates the cradle 3 through gears 62, 63 and the second the rod 5 through lead screw 68. A manual locking mechanism 7 carried by the lower end of an arm 8 fixed to the shaft 4 of the cradle enables the gear-wheel 63 to be connected to the shaft (position A) or the shaft to be locked in a given position (position B). The motor M## is also used to rotate the stage 1 to the ejection position (Fig. 2) and the mechanism may be locked in this position by a pin 19, which engages a hole in the arm 8. The movements of motor M#R are controlled by a servo mechanism and a pair of limit switches 25, 26. Valve rod 60, ejection rod 20 and locking pin 19 are all controlled by cams on the output shaft of a motor 32 and energization of this motor is governed by a switch-actuating cam 17. The various motors, switches and valves are connected in a manner not described in detail to a programmer 90. The apparatus may include an optical microscope 80 for examination of the specimen E.

Abstract: 1,245,573. Frictionally controlled pivots. ARTHUR SHAW MFG. Ltd. 9 Dec., 1968 [7 Sept., 1967], No. 40874/67. Heading E2F. A hinge has two relatively rotatable components 1, 2, each of which has a flange 3. The component 2 consists of a cylindrical housing 5 of which one end is open and the other end is spanned by a wall having a circular aperture 6 concentric with the open end. The component 1 consists of a cylindrical portion 7, whose diameter is the same as the external diameter of the housing 5, which has a coaxial and tapped bore 8. One end of this bore opens into a groove 9 which extends diametrically across the end face of the cylindrical portion 7. A bearing member 11 of resilient and deformable material e.g. polyurethane has at one end a rib 12 which fits into the groove 9 and a peripheral shoulder 13 of diameter the same as the housing 5 and the cylindrical portion 7. The bearing member extends into the housing 5, its initial dimensions being slightly less than those of the interior of the housing, and is formed with a frusto-conical and coaxial pocket 14. The smaller end of the pocket coincides with the bore 15 which extends through the rib 12 and into the tapped bore 8, the larger end opens to the apertured wall of the housing. A frusto-conical, axially bored sleeve 16 fits inside the pocket 14 and the shank of a bolt 17 extends through the sleeve and the bore 15 to screw into the tapped bore 8, while the head of the bolt rests upon the large end of the sleeve; so that when the bolt is rotated in the appropriate direction the sleeve is forced into the pocket thereby expanding the bearing member and increasing the frictional resistance to rotation of the components 1, 2.
