Filed: 1923-04-04
Abstract: 212,138. Ruths, J. K., (known as Ruths, J.). April 4, 1923. Safety-valves. - Steam from a locomotive boiler is passed into a storer through a non - return valve and an overflow valve, Fig. 3, containing a diaphragm a counterbalanced by a spring b and actuating a cone d on a spindle c so as to admit steam to the storer when the steam pressure passes a determined valve. When pressure in the storer is excessive, the steam actuates a diaphragm f, Fig. 4, spring g and valve h to admit steam from the storer to a piston i which operates a valve l in the pipe L<4> against the action of a spring k, so that live steam may pass through to an injector which forces water through a spray in the storer.

Title: Apparatus for use in investigating fatigue phenomena and damping capacity
IPC: G01N3/38
Filed: 1945-04-16
Abstract: 590,262. Apparatus for testiug physical qualities. HIGH DUTY ALLOYS, Ltd., HANSTOCK, R. F., and MURRAY, A. April 16, 1945, No. 9428. [Class 106 (ii)] Apparatus for use in investigating fatigue phenomena and damping capacity comprises essentially electromagnetic means for inducing mechanical oscillation accompanied by alternat-. ing stresses in a freely suspended specimen, electromagnetic means whereby the mechanical oscillation generates an electromotive force, and in circuit with both said means an amplifier such as to supply alternating current at the resonance frequency of the specimen to maintain substantial stability of the amplitude of vibration of the specimen at a selected value. As shown in Fig. 1, a specimen 1 is suspended freely within an electromagnetic exciter unit 2 and a similar electromagnetic detector unit 3 and the specimen 1 is subjected to torsional vibrations. The units 2 and 3 which may be constructed as described in Specification 576,275 are connected respectively to the output and input terminals of an amplifier 5 so that any E.M.F. induced in the detector unit 3 by the oscillation of specimen 1 is amplified to provide in the exciter unit 2 the current necessary to maintain vibration of the specimen. A calibrated amplifier voltmeter combination 7 measures the voltage generated in the detector unit 3 which voltage is a measure of the amplitude of the vibration and/or stress induced in the specimen.. In operation, an alternating torque of constant frequency is applied to the specimen by keeping the output current of the amplifier 5 stable and the relation between the produced stress and number of oscillations is a representation of the " fatigue " of the specimen. To obtain a measure of the " damping capacity " the energy dissipated per cycle is found by observing the relation between the output current from the amplifier and the stress it induces as indicated by the voltage of detector unit 3. If desired, means may be provided for measuring this ratio directly and such means is described in relation to the drawing (not shown) accompanying the Complete Specification. The amplitude of the pendulum may be observed by the spreading of a beam of light falling on a small mirror 6 instead of by measuring the voltage of the detector unit 3.

Weft-replenishing mechanism; shuttles, positioning for weft-replenishing; lays; beat-up motions; shuttle-boxes.-In looms provided with automatic spool-changing mechanism, the shuttlebox 4, Fig. 2, at the spool-changing end of the lay or both shuttle-boxes are stationary and are separated from the oscillating part 3 of the lay. Upon indication for weft-replenishment, a pin 22 is moved by link and lever devices from the weftfeeler into engagement with a groove 12 in a clutch member 11 splined on a rotating shaft 10. A cam on the clutch member 13 is thereby caused to operate the transferrer which is provided with a give-way device which operates when undue resistance is encountered. The weft ends from the cops in the magazine 26 are secured to holding means on a belt 32. The shuttle is positioned in the shuttle-box by cam-operated link and lever devices 37, Fig. 4. In order to prevent damage to the shuttle-box due to an improperly positioned shuttle, a portion 19 of the front of the shuttle-box is hinged and controlled by a spring. The movable portion 3, Fig. 3, of the lay is mounted on swords 1 linked to levers 2 and is operated by cams 5, 6 engaging bowls 7, 8 on the swords and levers 1, 2, the cams being designed to cause the lay to dwell while the shuttle is in the shuttle-box.

Title: Improvements in and relating to the distillation of water
IPC: C02F1/46
Filed: 1947-04-11
Abstract: <PICT:0641429/III/1> In the distillation of water by continuously circulating it through a heat-exchanger and a vaporizer, compressing the vapour from the vaporizer and passing the compressed vapour to the heat-exchanger; the water is treated for the precipitation of impurities as a slurry, and the rate of circulation of the water is maintained several hundred times as great as the rate of evaporation. Water is circulated by pump 4 through the tubes of heat-exchanger 2, vaporizer 1 and duct 3, at a rate which is 600 to 1000 times the rate of evaporation.  The steam evolved passes through dome 17 and duct 9 to turbo-compressor 6 which operates at a compression ratio of 1.1 to 1.4; and the compressed steam is supplied to heat-exchanger 2 through duct 10.  Electrolysis of the water in duct 3 is effected by passing an electric current between aluminium electrode 14 and the walls of the circulating system; and this causes the impurities to form, together with aluminium hydroxide, a loose slurry which is continuously withdrawn by draining off a small fraction of the circulating water through duct 18.  Raw water, preheated in heat-exchanger 13 by the steam condensate (i.e. distilled water) from heat-exchanger 2, is supplied to vaporizer 1 through line 15.  With an effective temperature difference of about 5 DEG  C., across heat exchanger 2, the increase in temperature of the water during its passage through the heat exchanger is 0.5 to 1 DEG  C.; and thus only a small hydrostatic head is required to prevent ebullition in the tubes. The plant is adequately heat-insulated.  The gases disengaged by condensation of steam in the heat exchanger 2 are withdrawn from vessel 11.  If non-corroding steel tubes are used for the heat exchanger 2, the thickness of their walls should not exceed 1.25 mm.
