Abstract: 1,126,655. Valves. BELL'S ASBESTOS & ENG. Ltd. 9 Feb., 1967 [22 Feb., 1966], No. 7646/66. Heading F2V. In a fluid flow control valve, rotation, as by a hand wheel (4, Fig. 1, not shown), of an externally screw-threaded spindle 2, causes the spindle to reciprocate and hence a valve closure member 5, carried at the free end of the spindle, to move towards or away from its seat 10, there being a certain degree of radial play between the closure member and the spindle. Both the closure member and the seat are shaped, as at 8, 13 and 9, 14 respectively, so that the closure member is guided by the co-operation of parts 13, 14 to its correct position before final closure is effected by contact of parts 8 and 9. Interposed between the end 11 of the spindle 2 and closure member 5 is a disc 12 consisting of, or incorporating, polytetrafluoroethylene or other suitable fluorocarbon material, or alternatively either one or both of the spindle and closure member co-operating surfaces may be formed from such material. In either case, the disc serves to minimize rotation of the closure member with respect to the seat when pressed against it by the rotating spindle.

Title: Improvements in synchronising arrangements for use in telegraph or like systems
IPC: H04L7/00
Filed: 1926-03-19
Abstract: 273,371. Automatic Telephone Manufacturing Co., Ltd., Harrison, H. H., and- Smith, S. R. March 19, 1926. Synchronous movements.-The shaft of a telegraph instrument in a Baudot or like system is driven by a friction clutch whose action is automatically adjusted when phase differences arise between transmitter and receiver. Control of friction clutch. In the system illustrated, which is of the Picard type, the receiver shaft S2 tends to run slightly faster than the transmitter : it is driven from a shaft S1 through a friction clutch which acts as a centrifugal governor, the arms B flying out so as to relax their frictional grip if the speed increases. The arrangement is such that so long as strict synchronism obtains the relay armature CRT remains in the position shown, but as soon as the phase of the shaft S2 leads that of the signals, the armature CRT short-circuits the resistance RR and so increases the current through the fixed magnet C, which encircles the shaft S2. The armatures A, which are pivoted on the disc D2 revolving with the shaft S2, are consequently attracted, so as to relax the frictional grip of the clutch pads FP; the shaft S2 therefore slows down until the armature CRT again makes contact. Arrangement of distributor and relays. The brush CBA passes over two segments a, b in succession during the receipt of each signal element. The segments a, a are for controlling the armature SRT of the relay SR, while the segments b, b are for charging the condenser CN through one or other of two oppositely wound coils of the relay CR. A negative current from a segment a sets the armature SRT to the left, so that the following negative current from a segment b charges the condenser CN through the upper coil of the relay CR, the effect being to keep the armature CRT closed. Similarly a positive current from the segment a sets the armature SRT to the right, so that the current from the next segment b passes through the lower coil of the relay CR, but since this current is positive and the relay coils are oppositely wound, the armature CRT is still kept to the left. So long therefore as synchronism obtains this armature is closed, but when the distributor leads so much that a change in the sign of the current occurs after the brush CBA has left a segment a, the relay CR is reversed, and the resistance RR is short-circuited so that the shaft S, is slowed down.

A method for the on-stream measurement of a parameter correlated with the flash point of a flammable liquid, comprises establishing in a chamber 13 which is maintained at a constant temperature, liquid/vapour equilibrium between a stream of sample fed to an inlet 11 and a stream of a carrier gas fed to an inlet 14, separating excess liquid by allowing it to leave via an exit line 15 burning the vapourised sample at a burner 17 with an auxiliary gaseous fuel which is preferably the carrier gas and measuring a property of the flame, e.g. its temperature, this property being related to the flash point of the sample liquid. The apparatus shown is formed from a single metal block and is maintained at a constant temperature by a thermostat (not shown). Oil to be tested is led to a riser 12 from which it issues into the chamber 13 from two holes 20, 21 below a cap 19, the oil running down the outside of the riser 12. Hydrogen is used as the carrier gas and auxiliary fuel and the gases from the chamber 13 pass through a mixing chamber 16 on the way to the burner 17 to ensure uniformity of the sample. A thermocouple 18 may be used to measure the temperature of the flame, but in cases where the sample is highly involatile, the parameter measured is preferably the electrical conductivity of the flame.

In a method of zone-melting a metal oxide rod, the molten zone is heated by the passage therethrough in an atmosphere of air of an arc discharge between two electrodes consisting initially of the metal. During zone-melting, a molten tip of metal oxide may form on one or both electrodes. As shown in Fig. 1, a molten zone 4 is formed in a rod of sintered nickel oxide by the passage of an arc between cooled nickel electrodes 5 and 6 with the formation of molten tips 15 and 16. As shown in Fig. 2, a molten zone 23 is formed in a rod of sintered alumina by the passage of an arc between cooled aluminium electrodes 26 and 27. Electrode 26, which is surrounded by cooled copper tube 33 and alumina tube 31, forms a molten mushroom-shaped end 38, the portion 37 of which becomes oxidized. Electrode 27, which is surrounded by alumina tube 34 and cooled copper tube 35, is intensively cooled so that substantially no melting takes place and the aluminium is only slightly oxidized.
