Title: Improvements in or relating to automatic power factor control
IPC: H02J3/18
Filed: 1946-03-26
Abstract: 627,213. Automatic control of power factor. ORR, J., and TELEGRAPH CONDENSER CO., Ltd. March 26, 1946, No. 4306. [Class 38 (iv)] Automatic power factor control in an A.C. circuit is effected by applying to a fixed capacitor associated with the circuit a voltage which is modified directly by an induction regulator or equivalent device under the control of mechanism directly associated with the circuit wherein control is to be effected. The controlling device may be actuated by means directly sensitive to variation in power factor or reactive K.V.A., or responsive to a quantity such as voltage, current, or power, which is dependent on the power factor. As shown in Fig. 1, the stator windings 4 of an induction regulator are connected across the A.C. mains 1 by leads 6, and the rotor winding 8 is connected in series with a condenser 2 across the same leads. The angular position of the rotor relative to the stator is adjustable in either direction by a reversible motor 15 energized from supplementary mains 16 or from the supply- 1 and provided with alternative terminals 22, 23 connected to contacts 20, 21 respectively which co-operate with a contact 19 on a movable arm 14. The arm 14 is connected by a lead 18 to one supply line 16, the other being connected to motor terminal 17. Movement of the arm 14 is effected in known manner under the simultaneous control of a voltage coil 9 and a current coil 11 fed from a current transformer 13. In a modification, Fig. 3 (not shown), a movable armature 36 arranged similarly to the arm 14 is controlled by a solenoid 34 which is connected across the mains and subjected to variations in the effective mains voltage. A similar arrangement controlled by a current transformer is also described. In a further modification, Fig. 2 (not shown), the induction regulator comprises two series - connected oppositely wound windings 26, 27 spaced on the same limb of a closed magnetic core 28 and connected across a condenser 2. A short-circuited coil 29 located between the windings 26, 27 and movable relative thereto along the core is carried by a block 33 in screw-threaded engagement with a rod 32 which is rotated under the control of mechanism similar to that of an integrating wattmeter and comprising a rotating disc 30 which is responsive to the effect of current and voltage coils as in the other examples. A torque magnifier may be interposed between the shaft carrying the disc 30 and the screw-threaded rod carrying the shortcircuited coil.

Title: Improvements in or relating to the purification of adrenal cortical hormone
IPC: A61K38/22
Filed: 1937-02-12
Abstract: Adrenal cortical hormone is purified by treating a solution of the crude or partly purified hormone in an organic solvent with a strong acid, separating the acid layer, diluting it with water, extracting the diluted solution with a water-immiscible solvent, and removing the solvent.  After the dilution the acid solution may be neutralized before the final extraction, or the final extract may be treated with sodium bicarbonate to remove traces of acid.  The starting material may be the intermediate alcoholic solution obtained before the treatment with a zeolite according to the process described in Specification 383,992; this solution is evaporated in vacuo, the residue taken up in benzene, extracted with strong sulphuric acid, the acid layer diluted with water, extracted with ether and the ether extract shaken with sodium bicarbonate, dried with anhydrous sodium sulphate and evaporated. According to another example the starting material is an ether solution of the hormone prepared according to Specification 383,992, including the step of purification with a zeolite, and this solution is extracted with strong hydrochloric acid.
Patent GB-696842-A (GB)
Title: Improvements in gas discharge tube circuits
IPC: H03K17/52
Filed: 1951-02-22
Abstract: 696,842. Valve circuits. GENERAL ELECTRIC CO., Ltd., CHUBB, A. A., and SCOWCROFT, J. Jan. 18, 1952 [Feb. 22, 1951], No. 4329/51. Class 40 (vi). A multi-stable state circuit comprises a number of gas-filled discharge tubes having their cathodes (or anodes) and trigger electrodes connected respectively in parallel, the cathodes (or anode) circuits being connected via a common impedance to one side of a supply voltage source, the other side of which is connected via electro-magnetic switching devices to the anode (or cathode) circuits so that a single tube fires on applying a triggering voltage to the common trigger electrode lead. Fig. 1 shows three cold-cathode gas discharge tubes GA, GB, GC having their cathodes connected in parallel to a cathode load resistor RZ, and their trigger electrodes connected in parallel via resistors to starter-switch st. The positive and negative voltages P and N are such that normally all of the tubes are non-conductive but when the starter-switch ST is closed and then opened again the increased voltage on the common trigger electrode causes one tube, for example tube GB, to fire. The associated relay B is operated, thus closing the " work circuit " at contact b2 and disconnecting the relay from the tube at contact b1, the relay being held operated over contact kb and tube GB being extinguished. During the period when tube GB is firing the voltage drop across resistor RZ reduces the trigger-electrode/cathode/voltage of tubes GA and GC so that neither can fire. A subsequent operation of the starter-switch ST causes either tube GA or GC to fire in dependence upon the differences in their characteristics and the action is repeated until all relays have been operated. The circuit may be restored to its normal condition by momentarily opening the contact, for example kb of each operated relay. In a modification, Fig. 2 (not shown), the operation of a relay disconnects the relay from the circuit of the respective discharge tube and also opens the trigger-electrode circuit of the tube. In a further modification, Fig. 3 (not shown), resistor-capacitor time constant circuits are associated with the trigger electrode circuits of the discharge tubes so that successive triggering actions cause the tubes to fire in a pre-determined sequence. Fig. 4 shows a further modification in which the discharge tubes have a common anode load resistor RZ and the relays are included in the cathode circuit, the firing of a tube disconnecting the relay from its respective cathode circuit. Each relay is shunted by a capacitor CA, CB, CC so that the inductance of the relay coil does not delay the rise in anode current in the discharge tube circuit.

Title: Hydraulic or pneumatic actuators of the cylinder and piston type
IPC: F15B15/14
Filed: 1972-02-01
Abstract: 1387475 Fluid operated actuators SOC D'APPLICATIONS DES MACHINES MOTRICES 1 Feb 1972 [3 Feb 1971] 4727/72 Heading F1D An hydraulic or pneumatic actuator comprises an output rod 3 carrying pistons 5a, 5b slidable thereon, the pistons 5a, 5b being reciprocable in a main drive rod 1 having pistons 7a, 7b which are themselves reciprocable in a cylinder 2, and the rod 3 being normally pulled along with the main rod 1 but being displaceable relative to the rod I upon experiencing a predetermined external force. An annular chamber 6 between pistons 5a, 5b is connected via passage 10 in rod 1 to a further annular chamber 8 between pistons 7a, 7b which is in turn connected to a source of pressure via a passage 9 in cylinder 2. Passages 11a, 11b convey fluid into cylinder 2 for reciprocation of main rod 1. The pressure in chamber 6 urges pistons 5a, 5b apart against stop collars 3a, 3b on the rod 3 and against abutments la, 1b formed internally of rod 1. Thus it can be seen that rod 3 will normally follow all movements of rod 1. However, if an external force on rod 3 in either direction exceeds the force separating the pistons 5a, 5b due to the pressure in chamber 6, then a respective piston 5a, 5b will be moved by its associated collar 3a, 3b towards the other piston which will be held against its respective abutment 1a, 1b, Fig.3. The pressure in chamber 6 will remain constant and only when the external force F3 falls below the predetermined value will the original configuration, Fig.1, be restored. Applications of such an actuator are described Figs.4 to 6 (not shown) and an actuator in which the rod 3 is sensitive to an external force only in one direction is also referred to Fig.7 (not shown).
