Title: Apparatus for Extracting an Ingot from a Curved Mould of a Continuous Casting Plant.
Inventor: BYKOV VLADIMIR ALEXANDROVICH
IPC: B22D11/128
Filed: 1967-04-13
Abstract: 1,188,816. Continuous casting. ORDENA LENINA, ORDENA KRASNOGO ZNAMENI I ORDENA TRUDOVOGO KRASNOGO ZNAMENI ZAVOD TYAZHELOGO MASCHINOSTROENIA IMENI S. ORDZHONIKIDZE. 13 April, 1967, No. 16967/67. Heading B3F. A cast strand is extracted at a constant speed from a curved-axis mould (and simultaneously cooled) by the added weight of curved, moving bars which clamp on the strand at intervals of time, the bars being arranged in two groups, the bars of one group being interdigitated with those of the other, each group comprising two sets 1, 1<SP>1</SP> or 2, 2<SP>1</SP>, one set on each side of the strand. A lever 10 moves the bar group 1, 1<SP>1</SP> down the strand path so that it attains the strand speed before the bar sets 1 and 1<SP>1</SP> clamp together on the strand and a lever 11 does the same for the group 2, 2<SP>1</SP>, starting a little later. When both groups are gripping the strand, the sets of bars of one group move apart and the corresponding lever returns them back along the strand path. The groups travel (on tracks 5) on wheels 4 the axles of which are driven by crankshafts 3 by which the bars are moved together and apart. Tie-bars 7, 8, 9 connect the crankshafts 3 to cranked axles 6 on which the bars of the upper sets 1<SP>1</SP>, 2<SP>1</SP> are pivoted. The strand is cooled by the clamping surfaces behind which are coolant ducts (12) in the bars. Reference has been directed by the Comptroller to Specification 842,358.

Title: Improvements in apparatus for controlling mechanism by means of light
IPC: H01H47/24
Filed: 1928-06-12
Abstract: 312,508. General Electric Co., Ltd., and Eden, E. M. June 12, 1928. Light radiations, control of apparatus by.-A photoelectric cell in series with a current-limiting device and a source of potential greater than its sparking potential and so adjusted that incidence of light on the cell stops or diminishes the frequency of a series of discontinuous discharges passing through it, as described in Specification 288,783, is combined with a relay comprising an unstable system retained within part of its range by discontinuous forces, controlled by the cell, which decrease rapidly as the system approaches the limit of its normal range, and departure of the system from this range closes or opens an electric circuit or otherwise sets further mechanism into operation. The relay comprises an unbalanced beam 1 pivoted on an axis 3, of which the inclination to the vertical is adjusted by an adjustable foot 17 on the base 8 so that an armature 9 on the beam tends to swing away from an electromagnet 15. The electromagnet is energized by the discharges from the cell (Fig. 4, not shown), and if these cease owing to light falling on the cell, the beam swings until contact studs 10 on its underside meet spring contacts 11 on the base.

Title: Improvements in or relating to winding-machines for yarns and threads
IPC: B65H67/056
Filed: 1945-07-05
Abstract: 602,001. Winding yarn &c. COMPTOIR DES TEXTILES ARTIFICIELS, SOC. A.R.L. July 5, 1945, No. 17240. Convention date, Oct. 26, 1944. [Class 120(ii)] The bobbins B, B' of a thread &c. winding machine are rotatably mounted on axes a, a<SP>1</SP> attached to frames s, s<SP>1</SP> pivotally mounted on a shaft 2. The bobbins are driven by the frictional contact of rollers R, R<SP>1</SP> driven by belts 11, 11<SP>1</SP> from pulley 12, 12<SP>1</SP> on a shaft 8, the rollers being urged into contact with the bobbins by the weights P, P<SP>1</SP>. Stops limit the movement of the frames b, b<SP>1</SP> which carry the driving rollers. The thread &c. after passing over a fixed guide pulley 17 is traversed by a guide 18 reciprocated by a bar 19 carried on rollers 20 and actuated by a cam 27 and pivoted rod 22. The cam 27 is feathered to its driving shaft 28 and is moved by a cam 37, rotating at slower speed, when bobbin B is completely wound, to traverse the thread on to B<SP>1</SP> (or vice versa), the unwanted thread between the two bobbins being severed by a knife (not shown). A manually operated bolt V is withdrawn when a bobbin is wound, in order that the frame S, S<SP>1</SP> may be swung outwards to a doffing position and an empty bobbin replaced. To effect uniform tension of the feed yarn, (Fig. 4), it is led from the pulley 17 about a roller S carried at the mid-point of an arm 43 oscillated about a fixed pivot 44 by a slotted connection 45 with the reciprocating bar 19, and then about a roller t on an arm 41 attached to the bar. The effect of this arrangement is to keep the length of thread between the roller 17 and the guide 18 constant at all times.

Title: Improvements in or relating to chemical balances
IPC: G01G23/02
Filed: 1961-05-11
Abstract: 905,530. Weighing apparatus. METTLER, E., [trading as METTLER, FABRIK FUR ANALYSENWAAGEN E.]. May 11, 1961 [Nov. 18, 1960], No. 17251/61. Class 143. A chemical balance having an asymmetrical beam supporting a counterweight at one end and having a support knife-edge for the beam and an end knife-edge for the scale pan and balance weights is provided with arresting mechanism, to relieve the knife edges of load, which comprises means located adjacent to the support knife edge 11 to lift the beam 4 from the position in which it is supported by the knife edge, means located adjacent to the end knife-edge 12 to lift the members supported thereby and stop means located adjacent to the end knife-edge 12 to limit rotation of the beam about the beam lifting means under the action of the counterweight 7 when the beam is in its arrested position. The scale-pan is suspended through a tie-rod 18 from a member 17 at the end of the shorter arm 5 of the beam. The knife-edge 11 is lifted off its thrust-block 22 by vertical pins, only one of which, 34, is shown and the member 17 is lifted off its knifeedge 12 by vertical pins 31, 32, 33. All these vertical pins project from the top 30 of a sliding member 27 which is raised and lowered by a cam 36 on rotation of a shaft 38. The support 9 of the knife-edge 12 also has a bearing 13 on which a pin 26 is caused to press downwards when the knife-edge 11 and member 17 are lifted, so counteracting the tendency of the counterweight 7 to tilt the beam. The pin 26 is mounted on a sliding member 23 which is raised and lowered by a cam 37, on the same shaft 38 as the cam 36 but so arranged that the same rotation of the shaft which raises the member 27, lowers the member 23. The members 23, 27 are guided by flat springs 24, 25 and 28, 29 respectively. In a modification, the means 23 could be dispersed with and the lifting means 27 given a longer stroke, the pin 26 then being stationary. In another modification there could be separate sliding members for lifting the knife-edge 11 and the member 17. 8 is a graduated dial to read the inclination of the beam.

Abstract: 1,175,404. Semi-conductor devices. THOMSON-C.S.F. 17 April, 1967 [25 April, 1966], No. 17609/67. Heading H1K. A semi-conductor device comprising a series arrangement of a dielectric and a semi-conductor body is biased via electrodes on the dielectric and body. The relationship between the dielectric constants of the layers, the breakdown field of the dielectric and the avalanche field of the semi-conductor is such that the avalanche field is obtained before the dielectric breaks down, and the bias is such that the field in the semi-conductor is near the avalanche field. Suitable semi-conductors are silicon, germanium and gallium arsenide, used in conjunction with the dielectrics barium titanate and tantalum pentoxide. A photodetector of this type is biased so that the avalanche field is exceeded at the insulator-semi-conductor interface and has a transparent electrode on the insulator through which incident photons or alpha particles are received. In an oscillator diode the semi-conductor comprises P, #, and P+ layers with the P layer directly abutting the dielectric.
