[Also in Division F2] The valve body 1 of a tank filling nozzle 5 houses an automatic cutout valve 4 which operates when the level of liquid in the tank closes the nozzle mouth; the valve is carried by a stem 3 which is retracted from a valve seat 2 by a pistol grip 7 against a spring 3A and held open by a catch 11 controlled by a diaphragm 10. One side of the diaphragm is connected to a passage 15 leading to the valve seat, and also to a detector passage 12 leading to the nozzle mouth. When the liquid level in the tank reaches and closes the nozzle mouth, the mouth of the passage 12 is also closed, whereupon the diaphragm is raised and the catch 11 withdrawn and the valve closed. A ball valve 20 is located within the valve body and in the passage 12, and the ball drops on to its seating to close the passage 12 if the nozzle should fall from the tank, thereby causing the retraction of the catch 11 and closure of the nozzle valve 4. In a modification, Fig. 5, not shown, a ball valve 29 is associated with a timing device 35 adjacent the diaphragm and including a magnet 36 which attracts the ball to its seating after a predetermined time.

Patent GB-638196-A (GB)
Title: Improvements in or relating to the preparation of hydroxy aromatic carboxylic acids
IPC: C07C51/15
Filed: 1948-05-08
Abstract: Mono-hydroxy mono-carboxylic acids of the benzene and naphthalene series are obtained by the action of carbon dioxide on a dry solution of an alkali metal phenolate or naphtholate in a dialkyl ketone which is liquid at ordinary temperatures and has a boiling point of at least 75 DEG  C.  Various substituents may be present in the nucleus but at least one of the positions ortho to the hydroxy group is preferably unsubstituted.  Methyl isobutyl ketone is the preferred solvent for naphthols and di-isobutyl ketone for phenol itself, these being substantially immiscible with water.  The reaction is preferably carried out at least 10 degrees below the boiling point of the ketone, carbon dioxide being passed in and the di-salt of the hydroxy acid being precipitated.  This is filtered off and a further portion of alkali and phenol or naphthol added, giving after dehydration a solution which may be again reacted with carbon dioxide.  The free hydroxy-acid is liberated from the salt and isolated in various ways.  Examples show the preparation of 1-hydroxy-2-naphthoic acid, 2-hydroxy-1-naphthoic acid, salicylic acid and 5-benzyl-salicylic acid.  Specifications 384,619, 460,282, 483,795 and 511,393 are referred to.  Solutions of alkali phenolates or naphtholates in dialkyl ketones are obtained by mixing a solution of the phenol or naphthol in the ketone with alkali metal, or concentrated aqueous alkali; in the latter case the water is removed by distillation.  If the ketone is substantially immiscible with water, e.g. methyl isobutyl ketone, the distillate is separated and the ketone layer returned to the reaction vessel.  When using water-soluble ketones such as methyl ethyl ketone, an azeotrope distils and fresh dry ketone must be added to replace that removed.

Patent GB-371172-A (GB)
Title: A process for the preparation of 2-mercaptobenzothiazole
Filed: 1931-04-30
Abstract: 2-Mercaptobenzthiazole is prepared by heating molecular quantities of aniline, sulphur, and carbon bisulphide for about 24 hours in an autoclave at a temperature of about 200 DEG  C. and under a hydrogen sulphide pressure of about 50 atmospheres.  The product is obtained in a yield of about 95 per cent and requires no purification by reprecipitation with acid.  The hot contents of the autoclave can, however, be obtained in one operation in a state of high purity by discharging them into a mixture of benzene hydrocarbons having an initial boiling-point of about 135-140 DEG  C. The greatest purification is obtained by using a mixture of hydrocarbons of suitable boiling-point (such as unwashed solvent naphtha II of boiling-point 150-180 DEG  C., or a mixture of middle runnings from a benzol distillation), containing about 5 per cent of phenolic bodies and 1 per cent of pyridine bases. Specifications 283,661 and 283,679, [both in Class 2 (iii), Dyes &c.], are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) relates to the production of thiazoles generally by the above process; this subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electronic control circuitry for delivering a control signal output in response to ionising radiation
IPC: G01T1/18
Filed: 1959-04-16
Abstract: 922,717. Control systems for Geiger tubes. MINNEAPOLIS - HONEYWELL REGULATOR CO. Aprli 16, 1959 [April 17, 1958], No. 12976/59. Class 38 (4). [Also in Groups XL (b) and XL (c)] A non-self-quenching Geiger tube 10 is quenched by connecting the collector (anode) and cathode electrodes 11 and 12 respectively to the anodes of two valves 13 and 14 forming a monostable multivibrator such that normally V13 is non-conducting and V14 is conducting so that when the Geiger tube 10 is ionized it becomes conductive and connects the control grid of V13 to the anode thereof thereby triggering the multivibrator into its unstable state (V13 conducting, V14 non-conducting) and hence making the cathode 12 of the Geiger tube positive relative to the collector 11 thereby quenching the tube. A positive output pulse is derived from the anode of V14. The cathode heaters 21, 22 of the valves 13 and 14 are connected in series and the heater 22 is shunted by a resistor 90 so that when the equipment is switched on the cathode of V13 heats up before that of V14 thereby ensuring that the operating voltage is not applied to the Geiger tube 10 until the valve 13 is capable of being triggered. In a modification, Fig. 2 (not shown), the multivibrator comprises a double triode with a common cathode connected to a cathode resistor, the anode of each triode being R.C. coupled to the grid of the other triode. The Geiger tube may be used for monitoring the flame of a fuel burner.
