Title: Improvements in systems for the automatic regulation of power factor
IPC: H02J3/18
Filed: 1944-11-03
Abstract: 592,622. Automatic control systems. HATHAWAY, R., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov.3, 1944, No. 21591. [Class 38 (iv)] Power factor.-In an automatic power factor correction system, progressive connection or disconnection of condensers is under the control of a relay-controlled rotary switching apparatus which, if the power supply fails, is prevented from exercising control of power factor until it has returned to its zero position. In Figs. 1 and 2, the power factor of a supply BB1, BB2 is automatically corrected by the progressive connection or disconnection of condensers C1, C2, C3 ... through contacts NJ2, NJ3, NJ4 ... of a drum switch (not shown) controlled by a reversible electric motor. One of the motor fields M1 is connected in series with the supply while the other M2 is energized in one sense or the other through contacts LL from a potential divider PR across'the supply. Contacts LL are controlled by a relay responsive to power factor having a voltage winding VC and a current winding CC, the arrangement being such that when the power factor is lagging, the motor rotates in one direction to connect the condensers progressively until the power factor is unity, while if the power factor is leading, the motor rotates in the opposite direction to disconnect the condensers progressively until the power factor is unity. Contacts NJ1 are closed by the drum switch at its " off " position to energize a relay RR which is normally maintained energized at other positions of the drum switch by self-holding contacts RR1. Should the supply fail when the drum switch is at a position other than its " off " position, however, relay RR is deenergized and is not re-energized on restoration of the supply. On restoration of the supply, therefore, (a) contacts RR4, 5, 6 are open so that the condensers are disconnected and a possible dangerous surge prevented ; (b) contacts RR3 are closed so that the motor rotates the drum switch to its " off " position at which relay RR is re-energized. Rotation of the motor in the opposite direction during this resetting is prevented by open contacts RR2. Limit switches LS1, LS2 limit travel of the motor in each direction. Operation of contacts RR1 may be delayed so that relay RR is not responsive 'to a momentary drop in' supply voltage. The drum switch contacts may control the connection of the condensers through relays.

Title: Improvements in writing instruments
IPC: B43K8/16
Filed: 1934-07-26
Abstract: 440,823. Fountain pens. KENT, A. F. S., Holm Ray, Iron Acton, near Bristol. June 26, 1934, No. 21828. [Class 146 (iii)] The writing-member A of a self-filling stylographic fountain pen, made up of a number of wires or the like arranged side by side, is arranged for longitudinal movement in one or more cores of wire D, and is also associated with a feed-bar B and a point-section C connected with the reservoir. The member A carries a valve E and a pressure plate F adapted, under the influence of a spring G, to seat on the end of the feed-bar B or a portion of the point-section C so as to interrupt the flow of ink when the pen is not in use, pressure on the point during writing causing'the valve to be lifted. The rear end of the spring may rest against a part of the section C or a plug H secured therein, or on a second valve P which acts to close the passage from the reservoir in case too great a pressure is applied to the point. The action of the spring can be controlled to suit the needs of different writers by adjusting the position of the feed-bar relative to the point section. The cores D may be arranged concentrically, in which case one or more of the coils may be secured to the point A and arranged to move with it while the other or others remain fixed. The flow of ink to the point may be facilitated by the introduction into the channel through the feedbar of fibrous or porous material so as to provide a number of capillary channels serving to draw ink from the reservoir. The movement of the member A during writing prevents choking of the channel and acts to clear away any solidified ink. The passage through the plug H may be continued by a coiled wire and a tube extending into the self-filling sac to facilitate filling. The exposed end of the writing-member may be partly enclosed by a shield in order to reduce evaporation, and an aperture may be formed in the feed-bar to equalize pressure inside and outside the reservoir.

Abstract: 1,069,866. Purification of oxygen. AIR REDUCTION CO. Inc. May 25, 1965 [June 2, 1964], No. 22105/65. Heading F4P. Commercially pure oxygen is freed of low boiling impurities by compressing at (106), Fig. 1 (not shown), cooling to saturation temperature in a pass (110c) of a heat exchanger (110), condensing at (115) at the base of a rectification column (113), withdrawing hydrogen, helium and nitrogen impurities from the condenser (113) through a duct (116), expanding the partly purified liquid oxygen through a valve (120) into the upper end of column (113), withdrawing argon and nitrogen gas from the head of the column through a duct (126) and after passage through a pass (110a) of exchanger (110), returning at least a portion to the inlet of the compressor (106) and withdrawing product gas from above the pool of liquid oxygen collecting at the base of the column (113) and serving to cool condenser (115) through a duct (122) provided with a motor operated valve (134), and leading to a liquid nitrogen cooled condenser (128) from which product liquid oxygen is withdrawn through a valve (130). Nitrogen for cooling condenser (128) and a condenser (118) at the head of column (113) is supplied from a reservoir (124) and the resulting nitrogen vapour traverses a pass (110b) of exchanger (110). The valve (134) is controlled by a servo device (107) responsive to the argon content of a sample withdrawn from the column (113) at a point (114a), to the flow of saturated feed oxygen entering the column through a duct (112) and to the composition of product gas in duet (122). The methane content of the feed gas is removed by a conventional catalyst chamber (103). In a modification methane is removed from feed liquid oxygen in a preliminary rectification column (351), Fig. 3 (not shown). In a further modification the gaseous oxygen leaving the base of the column (413), Fig. 4 (not shown) through valve (434) is freed of methane in a catalyst chamber (426) prior to liquefaction in a condenser 428.

Filed: 1955-08-02
Abstract: 788,873. Selective pipe-coupling devices. SIMON HANDLING ENGINEERS, Ltd. July 10, 1956 [Aug. 2, 1955; April 3, 1956], No. 22126/55 and 10105/56. Class 99(1). In a device for selectively connecting pneumatic pipe lines 17, 18 and 19, the latter are fixed in a rigid casing or frame 1 within which is disposed at least one pipe 2 arranged in such a way that the pipe can, by rotation or sliding thereof, be caused to interconnect the selected pipe lines, there being sealing means comprising hydraulically or pneumatically-expanded, hollow, elastic rings 8 at the joints between the pipes. As shown in Fig. 1, the flanged pipe 2 is carried by a disc 3 and a bearing 5 and is rotatable about an axis X-Y, the disc having gear teeth which are engaged by a pinion 6 driven by an electric motor 7 mounted on the frame 1. The pipes 17, 18 and 19 are fixed in the frame by collars 9 recessed to accommodate the rings 8 connected by metal pipes to a piston-cylinder device 11 the piston 13 being depressed by a weighted arm 14 releasable by an electro-magnetic solenoid 16. Energization of the latter relieves the piston of pressure thereby releasing the fluid pressure in the rings 8 and the motor rotates the pipe 2 to the desired position when a limit switch is operated thus simultaneously stopping the motor and releasing the arm 14 so that the rings 8 are again expanded to form a seal with the face of the disc 3 and the pipe flange. The arm 14 may be raised manually, and the rings 8 may be accommodated in collars fitted to each end of the pipe 2. In modifications, (a) there are four pipes 20, 21 and 22, 23, Fig. 4, attached to the frame 1 and a rotatable unit comprising two straight pipes 24, 25 and two pipes 26, 27 which cross over from one side of the unit to the other, and (b) a straight pipe 32, Fig. 6, and a curved pipe 33 are carried by a frame 31 which is slidable to selectively connect the pipe 28 with the pipe 29 or 30.

Patent GB-152490-A (GB)
Title: Improvements in or relating to electric-motor control-systems
IPC: H02P7/288
Filed: 1919-09-11
Abstract: 152,490. Zweigbergk, T. Sept. 11, 1919, Master control systems. -In a control system of the type described in Specification 141,816, the master controller and extensions on each motor controller have series of contacts connected by relays which are arranged to short-circuit the auxiliary motor of the motor controller when it successively reaches the various positions corresponding with the positions of the master controller. The windings M<1> - - M<4> of the relays are connected between the contacts a' - - a<4> of the master controller A and the contacts l<1> - - l<4> of the motor controller extension L. The solenoid B<5> operates the main contactor B<2> and also a reversing-switch J for the auxiliary motor. When the master controller is moved to the first notch, the contactor B<2> closes the circuit of the working motor E through the starting-resistance D. The switch J makes connexions at the same time for the forward rotation of the auxiliary motor F but the rotation does not occur, since the armature is short-circuited by the contacts m<1> of the relay with a winding connected between the contacts a<1>, l<1>. When the master controller is moved to the second notch, the contacts m<1> fall open and the motor F rotates the motor controller to cut out the first section of resistance. The auxiliary motor F is then stopped by a shortcircuit through the contacts m<2> closed by the second relay with a winding M<2> between the contacts a<2>, l<2>. Further movement of the master controller produces a similar action. In a modification, an interlock prevents the contactor B<2> from being closed again after being opened until the master controller has been returned to zero. An additional relay is arranged with its contacts in series with the auxiliary motor and operative in the latter positions of the master controller. This enables each of the short-circuiting relays M<1>, M<2>, M<3> to be used twice.
