Abstract: 880,978. Indicating liquid level. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 3, 1959 [Jan. 27, 1959], No. 2988/59. Class 40 (1). A conducting probe 4 carried by a wire from a drum 1 driven by a reversible D.C. motor 6 is controlled to heat at the surface of a liquid 5 with the aid of a relay such as an A.C. excited thyratron 19 which is normally non-conducting and conducts when the probe makes contact with the liquid surface and so grounds the control grid. When the thyratron conducts, the effective field of the motor is reversed by winding 15 and the motor drives the probe clear of the liquid, the extent of the hunting excursions being governed by an eddy current brake 13. Motor 6 also drives an indicator 27 through a selsyn link and a lost-motion coupling 24 which prevents the indicator from following the hunting movements of the motor. To ensure that the lost motion and hunting motion have the same extent, a rheostat 14 adjusts the excitation of the eddy current brake. The indicator pointer 26 makes a number of revolutions indicated by a counter 28. With the aid of reversing switches, the probe may be made to locate a datum position 29.

Abstract: 228,898. Gosselin, B. J. X. Feb. 6, 1924, [Convention date]. Electric clocks. - An electrically-controlled pendulum arranged to give periodic emissions of current comprises a pendulum A provided with a metal needle E which at each oscillation cuts the meniscus of a mercury bath F. The pendulum carries a steel armature C in close proximity to an electromagnet D-D, while the bath F is connected at G to an electromagnet A and an armature I, as shown in Fig. 1, and at each oscillation of the pendulum the needle E contacts with the mercury and gives rise to a current in the circuit M, S, H, G, A. The movement of the pendulum is maintained by a derived current which traverses the circuit J, K, D, D, M, B, but, upon the passage of the first current, the magnet H attracts the armature I and breaks the circuit through the electromagnet D-D. The mercury F<2>, Fig. 2, is carried in a receptacle X having flexible walls, and the meniscus F<1> is maintained as desired by the pressure of a piston Y on the receptacle X, the said piston being controlled by a screw W. The electromagnet D-D may be carried on a screwed support permitting fine adjustment of the air gap between the electrodes and the armature C.

Filed: 1964-01-24
Abstract: 1,058,991. Filter press openers. MANOR ENGINEERING CO Ltd. Jan. 22, 1965 [Jan. 24, 1964], No. 3071/64. Heading B1D. A filter press has a reversible electrically driven carriage 11 mounted on a girder 10, which carriage carries a sprocket wheel 21 which is rotated when it contacts abutment 28 on the first plate 14 on moving from A to B in Fig. 1. The rotation of wheel 21 causes cams 26 to trip switches 29 which apply an electro-magnetic or mechanical brake 30 (Fig.3, not shown) to shaft 20 carrying sprocket wheel 21 thus preventing rotation, and which reverse the electric drive and direction of travel of carriage 11. The first plate 14 is thus entrained and moved towards position C where, when the plate comes to rest, the carriage continues in the same direction, the brake 30 being preadjusted to allow sprocket 21 to slip until the rotation of sprocket 21 caused by engagement with abutments 28 causes cams 26 to trip switches 29, thus releasing brake 30 and reversing the direction of travel of carriage 11, which returns to pick up the next tray. In an embodiment in which it is required to move more than one tray at a time, the carriage is provided with an additional third switch (34) (Fig. 2, which shows reverse side of Fig. 1, not shown) which is tripped by abutments 33 provided on certain plates only, which switch is so wired in conjunction with switches 29 that switches 29 are inoperative during travel of the carriage towards B until switch 34 is tripped, whereupon brake 30 is applied and the travel is reversed.
