Abstract: 850,199. Proportioning flowing liquids. MEDO APPARATEGESELLSCHAFT & CO. May 4, 1959 [May 2, 1958], No. 15240/59. Class 86 An apparatus for proportioning two liquid streams in flow measures the flow of each stream and varies one of them by means of a valve controlled by a differential circuit connecting the two flowmeasuring devices. The main flow actuates an impeller wheel 7 having a ring magnet 8 which deflects the beam from an electron tube 9. The supplementary liquid is supplied from a tank 10 by a pump 12 and actuates an impeller wheel 22 having a ring magnet 23 which deflects the beam of electrons from a tube 25. The impulses emitted by the two electron tubes 9, 25 are converted by the impulse converters 26, 27 respectively into voltages which are compared in the differential circuit 28, causing the motor 29 to rotate in one or the other direction according to which voltage is the greater; the motor actuates the diaphragm valve 17 to adjust the flow of the supplementary liquid accordingly. The support 5, the frame 6, the pipe section 21, the housing 24 and the impeller wheels 7, 22 are constructed of dia-magnetic material

Title: An improved lubricating arrangement for gas-storage installations, more particularly dry gas-holders
IPC: F17B1/04
Filed: 1953-06-03
Abstract: 733,520. Actuating reciprocating pumps. KLONNE, M., and KLONNE, A., [trading as KLONNE, A., [Firm of]]. June 3, 1953 [June 3, 1952], No. 15349/53. Class 102 (1). [Also in Group XXXIV] A lubricating device for use in gas storage installations, for lubricating the packing between the movable piston and the shell of a gas holder, comprises a lubricating pump or the like which receives intermittent impulses from the movement of the piston, this movement storing potential energy which is released at intervals. In the arrangement shown in Fig. 1, a gas holder 1 is provided with a piston 4, and packing 5 which slides along the shell 3 of the holder. A framework consisting of parts 6, 7, 27 supports a lubricating pump 25 with reservoir 24 and pulleys 14, 16 connected by a driving chain 15. The pulley 14 is engaged by a rope 9 which passes over pulleys 13, 12 and a weighted pulley 10 and is connected to the top of the gas holder. The pulley 16 is coaxial with a pulley 17 provided with a freely suspended arm 18 which has a grip pin adapted during rotation of the pulley to engage a driving lever 19 on the lubricating pump and raise it up until eventually the lever 19 is released and swings back aided by a counterweighted lever 21 to operate the pump and discharge lubricant to the packing. In a modification shown in Fig. 2, motion is transmitted to the pulley 17 by means of a roller 30 pressed against the shell 3 of the holder by a counterweight 28. The device is operated during both up and down movements of the piston, but ratchet-and-pawl means may be provided to cause operation of the device on movement of the piston in one direction only. During upward movement of the piston the grip pin 40, Fig. 4. of the arm 18 engages a rail 50 provided with a guide 51 which can be adjusted to vary the swing of the lever 19 before release. During downward movement of the piston the grip pin 40 engages an adjustable guide 41. In another arrangement the drive of the lubrication pump is effected by means of a rope provided at intervals with knots or balls which in turn, as the rope ascends, engage the enlarged end of a slotted driving lever on the pump, releasing the end after having traversed a certain distance.

Abstract: 609,204. Electric control systems. TUSTIN, A., MORRIS, D. G. O., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 17, 1940, No. 15387. [Class 40 (i)] In a system in which misalignment of the control member and a driven member as determined by a follow-up device causing operation of the driving equipment until realignment is effected, the element of the followup device associated with the driven member includes a damped oscillatory or resilient coupling arranged so that oscillary components of the movement of the driven member, e.g. in hunting movements, about the position of alignment, are applied with a phase lead to the associated element of the follow-up system. The driven shaft 1 carries a cylindrical casing 2 having fluid chambers' 8, 9 co-operating with vanes 10, 11 on the shaft which is torsionally connected to the casing by an annular indiarubber member 12 fixed to the shaft and to a ring 13 fixed to the cylinder. The shaft 1 has a fixed arm 18 linked or otherwise coupled to a crank 17 on a shaft 16 mounted in the cylinder and carrying a further crank 19 which extends beyond the axis of the cylinder and is linked to the disc 20 which constitutes the associated follow-up element. This element may be the rotor of the receiver of a selsyn distant control system or be one element of an electrical contact controller used in a local control system. The frequency of the oscillatory system may be such that there is substantially no phase lead at low frequencies so as to avoid interference with normal retardation effects. In systems employing low- and high-speed control for course and fine adjustment of the alignment, the invention is applied only to the high-speed fine control.
