Abstract: 1288276 Casting processes; moulds VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT ELEKTROTERMICHESKOGO OBORUDUVANIA 19 Nov 1969 56639/69 Heading B3F [Also in Division H5] In a mould for casting a hollow ingot, molten metal (from the melting of consumable electrodes or poured in through hollow electrodes 2 or around solid electrodes) passes through molten slag for refining; the wall 3, bottom 4 and a mandrel 5 are water-jacketed for cooling and electrodes entering the mould are mounted in holders 7. The slag, melted elsewhere, is kept molten by the electrodes. The mould cavity and mandrel 5 taper upwardly. The electrodes are raised as the mould fills, or the mould may be lowered. After solidification the wall 3 is raised and the hollow ingot lifted. In a modification, the mandrel (9) has a spigot base for insertion into the mould bottom (8) and the mould wall and mandrel, being interconnected, are raised off together to provide access to the ingot.

Abstract: 1305207 Semi-conductor devices NATIONAL RESEARCH DEVELOPMENT CORP 28 April 1970 [2 May 1969] 22482/69 Heading H1K [Also in Division H3] In an acousto electric oscillator including a body of semi-conductor material P in which the interaction between free carriers and lattice waves is sufficiently strong to give round trip amplification of the lattice waves, the body has a pair of opposite plane parallel surfaces and a resistivity close to the high resistivity limit of operation of the oscillator and means is provided for applying across the body a voltage whose value is close to the cut-off voltage, whereby the oscillator is mode locked to the lowest present harmonic of oscillation. A piezoelectric semi-conductor body P with the above biasing and resistivity conditions generates many modes of oscillation. The amplitude of each mode is constant and the modes have a fixed phase relationship to each other so as to be self mode-locked. The oscillator generates pulses (Figs. 2 and 4, not shown) and may be used as a clock pulse generator or an ultrasonic pulse generator (Fig. 3, not shown), which may be used for pulse echo measurements. The body P may be of photoconducting cadmium sulphide. The resistivity of the body P can be controlled, by illumination by some external source, to vary over a wide range by means of a photoconductive effect so that the resistivity required to satisfy the above conditions is selected. It is thought that the self locking is produced through modulation of the gain and/or velocity. Some frequencies which are not harmonics may be suppressed internally and in some cases an external filter may be required. The repetition frequency depends on the frequency separation between modes which may be controlled by variation of the resistivity, bias voltage or application of stress. Changes in pulse repetition frequency can be obtained by a frequency selective load such as a comb filter.

A bottle is pushed through a flap 13 and the cap 18 is forced between plate members 16, 21, whereupon the arm 6 returns for another bottle and the flap 13 closes. A jack 23 is then activated to force a piston-rod 24 on to the cap 18, which removes the cap from the bottle and ejects the bottle rearwardly until it engages the closed flap 13. The bottle then tilts forwardly and slides down a guide track 14 into one of a series of bottle supporting tubes 27. These tubes rotate in a step-wise manner, and in doing so the contents of the bottles held therein fall into a trough 31. The empty bottle, prevented from falling out by a plate 29, is then deposited on a conveyer 5. An electric motor 32 furnishes the drive to the various parts of the apparatus. The arm 6 is pivoted at 7 and reciprocates back and forth by means of a cam 53 driven by chain 49, and bottles are fed on to a platform 2 on the arm 6 by a hook 9 operated by cam 55, also driven by chain 49, and a rod 67.

In Fig. 1, the piston of the cylinder 5 and the eccentric 3 are connected by an arm 4. In Fig. 2 (not shown), the cylinder 5 acts on two arms 4 connected to two eccentrics 3 and the cylinder 9 acts on two toggle lever systems 12.

This reduces the deflection of the strip 12 and after some oscillation the valve 13 assumes an intermediate equilibrium position under its spring bias and the force of the strip 12. If the pilot flame is extinguished there is sufficient delay in the strip 12 cooling for the pilot to be relit by the main burner. If however the main flame also fails the valve 13 returns to its seat to shut off the gas supply to the main burner. The pilot is lit by a glow-coil and may have a separate gas supply.
