Title: Improvements in and relating to electric switches
IPC: H01H71/48
Filed: 1949-11-07
Abstract: 659,719. Controllers. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 7, 1949, No. 28482. Convention date, Nov. 10, 1948. [Class 38(iii)] Relates to a combined line switch, starting switch, and overload protective device for single-phase induction motors having starting and running windings. When a manual actuator member 16 is depressed to stop the motor it moves a deflector plate 17 so that a portion 23 thereof engages a bimetallic spring strip 6, causing separation of line contacts 5, 7. Release of the member 16 effects its return, under spring- action, to the neutral position 'shown, the bimetallic member 6 remaining in its lower over-centre position. Actuation of the member 16 for starting the motor causes a portion 24 of the plate 17 to engage the strip 6 and close contacts 5, 7. In this position starting contacts 26, 27 are closed, and a spring 34 engages a contact 15 to short-circuit a heater resistor 32. The circuit to the motor is made through terminal 3, contacts 5, 7, strip 6, and contacts 15, 34. From thence the main winding circuit is completed through the plate 17, supporting member 20, and terminal 22, the starting winding current passing through contacts 26, 27, supporting member 30, and terminal 31. When the member 16 is released contacts, 26, 27 open to de-energize the starting winding and the short-circuit is removed from resistor 32, the strip 6 remaining in its upper over-centre position with contacts 5, 7 closed to maintain the energization of the motor running winding. An overload during the starting period will produce sufficient current in the strip 6 to cause it to deflect, open contacts 5, 7 and stop the motor. During the normal running period the overload control is rendered more sensitive by the effect of the heater resistor 32. The contacts 26, 27 are preferably closed before the contacts 5, 7 during the starting operation. If the member 16 is retained in the starting position for an excessive period, the overload control will protect the starting winding from over-heating.

Title: Improvements in or relating to liquid measuring apparatus
IPC: G01F15/00
Filed: 1930-09-23
Abstract: 363,722. Zeroizing-mechanism. KENT, Ltd., G., 199, High Holborn, London, and HANDFORD, R. E., Biscot Road Works, Luton, Bedfordshire. Sept. 23, 1930, No. 28498. [Class 106 (i).] The pointer (or pointers) of a liquid measuring and delivering apparatus is zeroized by operation of a control device which releases a fork member to allow it to move under spring action to effect the zeroizing, the speed of the zeroizing and return strokes of the control device being under control to prevent too rapid operation. The flow of liquid through the pipe 2 operates a gyratory piston 45 (s u c h as is described in Specification 213,061, [Class 110 (ii), Rotary engines &c.]), the rotations of which are transmitted by a disc 51 and reduction &c. gearing 30, 33 to a spindle 4 carrying the pointer 6 and also to a spindle 40 driving at a reduced rate the pointer 7. On the spindles of the pointers are two cams 8, 9 for engagement by a fork member 10 carried by a rod 11 enlarged at 15. The rod is normally restrained against downward movement by detents 13 engaging a groove 12 but when the control knob 17 is depressed the detents are released and the rod descends under pressure of the spring 16 stressed by the depression of the knob. The latter is restored by a further spring 19 and violent movements in either direction are prevented by a dashpot piston 22 sliding in an annular oil chamber formed by the coaxial tubes 21, 24.

Filed: 1921-10-29
Abstract: 170,859. Constan, P. A. J. M. Oct. 29, 1920, [Convention date]. Hulls.-A method of determining the contours of the ships' sterns which will offer the least resistance to propulsion having regard to the remaining dimensions of the hull and the proposed speed consists in considering the trajectories of liquid elements located at selected distances below the water line at the midship section of the hull, assuming that the elements move laterally with velocities which are functions of their respective depths of immersion and of the speed of the ship. The resulting form of the stern is one in which its water lines are, as shown in Fig. 5, substantially straight, and from this figure the longitudinal and vertical sections of the vessel can be deduced by the usual processes.

Abstract: 601,352. Fluid-pressure servo motor-control systems. GRAVER TANK & MFG. CO., Inc. Nov. 1, 1945, No. 29001. Convention date, Nov. 27, 1944. [Class 135] [Also in Group I] In apparatus for removing the sludge from the bottom of a settling tank 10, the outlet valves 21, 16 are automatically closed when the viscosity of the sludge passing reaches a predetermined low value. The outlets from different parts of the tank join and pass to a drain 24 through an orifice 25 the pressure difference across which, controls a diaphragm switch 29. The diaphragm, switch is arranged to energize a latch-out coil which is part of an electrical circuit for controlling, through pilot valves, the valves 21, 16. In series with the diaphragm switch is a time-lag relay which ensures that the valves 16, 21 shaft remain open for a predetermined minimum period e.g. one minute. In operation a switch in the electrical circuit is momentarily closed, either by hand or at regular intervals by a repeating device, to energize a latch-in relay which opens the valves 16, 21. The flow then starts and continues until the sludge becomes so thin that the pressure difference across the orifice 25 is sufficient to close the diaphragm-switch 29. This causes the closing of the outlet valves 21, 16 to interrupt the flow. The period of flow may be four or five minutes. The different parts of the tank 10 may be emptied separately or simultaneously according to the setting of the manual valves 22, 17.

Title: Improvements in the production of artificial filaments and other shaped articles
IPC: D01F2/28
Filed: 1945-11-02
Abstract: Artificial filaments, films and other shaped articles are produced by extruding or otherwise shaping by the application of pressure a gel comprising an organic derivative of cellulose dispersed in an organic liquid which is a solvent for the cellulose derivative when hot, but a non-solvent at lower temperatures and subsequently removing the liquid from the shaped articles.  The gel is obtained by dissolving the cellulose derivative, e.g. cellulose acetate, particularly unhydrolysed acetate, cellulose propionate, butyrate, acetate - propionate, acetate-butyrate and ethyl benzyl cellulose, in the liquid at a temperature of, for example, 50-70 DEG  C., and cooling this solution to a temperature of 35 DEG  C. or below.  Suitable organic liquids are mixtures of propylene chloride or trichloroethylene with ethyl, propyl, isopropyl, butyl or isobutyl alcohol, mixtures of hydrocarbons such as benzene or toluene with methyl alcohol or any of the aforementioned alcohols and mixtures of ethylene chloride with propylene or butylene chloride.  The gels are shaped by extruding them under pressure, by moulding or by passing them between rollers and the organic liquid is removed from the shaped articles by passing them through an evaporative atmosphere or through an extraction bath of e.g. carbon tetrachloride. Filaments may be stretched simultaneously with their formation and films may be combined under pressure with paper, leather or cloth. Examples are given.
