Filed: 1964-01-20
Abstract: 1,041,294. Voltage stabilizers. DANJOSS A/S. Jan.20, 1964 [Jan. 19, 1963 ], No.2462/64. Heading G3X. A voltage stabilizer having both an A.C. output and a D.C. output comprises a transformer having a primary winding 2 for connection to an A.C. source 1 over a series impedance 13, preferably a choke coil, a secondary winding 3 for the D.C. output, and a tertiary winding 5 associated with rectifiers 10, 11 and a voltage stabilizing element 12 e.g. a Zener diode, a glow lamp or a voltage dependent resistor, for the D.C. output. The impedance 13, by virtue of which the output has a rectangular wave form, may be dispensed with if the transformer is of the type having a leakage path between the primary and other windings. In operation, the D.C. output at terminals 6 is stabilized in the normal manner by the element 12. The A.C. output is also stabilized by the element 12 which breaks down, to complete a circuit through the winding 5 and one of the rectifiers 10 or 11, when the voltage in the winding 3 exceeds the stabilizing voltage of the element 12, whereby the amplitude at A.C. output terminals 4 is maintained at a constant value.

Filed: 1971-01-19
Abstract: 1380582 Continuous casting DAVY-INTERNATIONAL Ltd 18 Jan 1972 [19 Jan 1971] 2536/71 Heading B3F  Metal, e.g. steel, is cast in a stationary horizontal mould 1, Fig. 1, and intermittently withdrawn by at least one pair of pinch rolls 20, 21, Fig. 2, at least one roll of the pair being driven by a motor and, after each withdrawal phase, the motor is reversed so that a push-back force is applied by the rolls to urge the casting back towards the mould with a force large enough to allow contraction of the casting back towards the mould but not so large as to cause displacement of the casting at the mould inlet, there being adjustable means, e.g. a pressure relief valve 39, operable only when the motor is reversed, for limiting the maximum torque applied by the motor.  As shown, rolls 20, 21 are driven by hydraulic motors 22, 23 connected in series (they may be in parallel) to be actuated in one or the other direction according to the position of a reversing valve 26. In the position shown, fluid from a pump 31 is passed to the motors 22, 23, by a line 27 (and returned by a line 28) to withdraw the casting. On switching the valve 26, pump 31 is by-passed through a coacting valve 30, and fluid from a pump 35 and a line 29 rotates the motors for push-back of the casting. A valve 38 may by-pass a flow control valve to increase the reverse speed of the rolls 20, 21 for driving a dummy bar to the mould. The rolls could be driven by electric motors and the push-back limited by adjusting the current in an eddycurrent coupling circuit. The copper mould 1 in a copper or steel coolant jacket has at its inlet an apertured silicon nitride plate 4 to which is sealed a refractory nozzle 10 of a tundish 11 by means of cement. The mould is separated from the pinch rolls by a secondary cooling zone.

Abstract: 1,089,511. Mixing proportionately flowing fluids. P. G. TACCHI. Jan. 15, 1965 [Jan. 22, 1964], No. 2808/64. Heading B1C. [Also in Divisions F1 and F2] In apparatus for mixing two fluids in constant proportions, e.g. cold water and steam, to form hot water, cold water is admitted at 12 to a high pressure chamber 10 and passes through a restrictive by-pass 18 to a lowpressure and mixing chamber 13. A pressure responsive element such as a bellows 35 separates the two chambers and operates a valve member 31 to admit steam from the inlet 27 to the chamber 13, hot water passing out at 46. An additional fluid (e.g. detergent) may be dosed into the hot water through passage 62 by a pumping device comprising a piston 47 attached to the bellows, a dose being injected every time closure of the outlet control valve, e.g. a spray lance, causes equalization of pressure across the bellows. The stroke of the pump at the size of the by-pass restriction are both adjustable; the latter may be done by a thermostatic capsule. The valve member 31 and its seat 63 may be replaced by others of different sizes. In a modification, (see Figs. 3-6, not shown) the pressure-responsive element is a spring-loaded piston and the pumping device comprises a cylinder attached to the piston and cooperating with a fixed plunger.

Title: Automatically resetting timing mechanism
Inventor: JONES GEORGE SHAPLEY
IPC: G04F3/06
Filed: 1963-01-23
Abstract: 1,059,721. Time switches. EASTMAN KODAK CO. Feb. 5, 1964 [Jan. 23, 1963], No 2816/63. Heading H2B. An electric timer motor drives a shaft via gearing and a clutch such that when the motor is de-energized the shaft is free to rotate, under action of a spiral spring, back to its starting position which is determined by a fixed stop being engaged by a projection on the periphery of a disc mounted on the shaft. The disc also carries on or near its periphery timing indicia and a further projection which engages a bell crank to actuate a two-position switch when the disc has been rotated for a time equal to, or somewhat greater than, the maximum marked on its periphery. This switch is in the circuit of the motor and is closed by manual operation of a retractive lever of a photographic copying apparatus with which the timer is associated. This lever also operates a series micro-switch which breaks the motor circuit only while the lever is in the operated position. Thus successive operations at intervals less than the maximum marked on the timer disc cause the micro-switch to momentarily de-energize the motor and allow the disc to return to its starting position and recommence a timing run. After a final run of a sequence the lever is not operated and the disc therefore rotates until it restores the twoposition switch which leaves the motor in a de-energized condition.

Filed: 1941-03-07
Abstract: 550,750. Metallic and silicon halides. CLEVELAND, F. J. (Pittsburgh Plate Glass Co.). March 7, 1941, No. 3140. [Classes 1 (ii) and 1 (iii)] In producing liquid halides of silicon or of a metal such as titanium, tin or vanadium, the volatilized halide is washed with a metallic halide or with silicon tetrachloride, carbon tetrachloride, difluoro dichloromethane, dichlorobenzene, benzyl chloride, dichloroethyl oxide, methylene dichloride or chloroform, introduced from an internal source. In one example, material containing iron and tin titanium or silicon is chlorinated to form the tetrachloride of the latter element, this is vaporized and then washed as above described, whereby suspended iron chloride may be substantially completely removed. A second washing with cold liquid halide to condense the tetrachloride may be utilized. In producing titanium chloride, preheated briquettes of titanium ore, carbon and molasses were treated with chlorine, the heat of reaction maintaining the reaction temperature and the gaseous mixture produced introduced into the apparatus shown, iron chloride being condensed in chamber 11, and a washing halide being introduced if desired through a sprayhead 25. Thereafter the gases are sprayed from head 17 with titanium tetrachloride, and finally cooled by a titanium tetrachloride spray from head 22. In producing tin halide, the iron may be converted to oxide by means of oxygen which is then removed by washing with, e.g. stannic chloride.
