Title: Manufacture of dihydropyridazinedione
Inventor: REED RONALD ARTHUR
IPC: C07D237/14
Filed: 1953-06-19
Abstract: 1 : 2 - Dihydropyridazine - 3 : 6 - dione (maleic hydrazide) is made by reacting hydrazine hydrate with an excess of maleic anhydride and/or maleic acid in an aqueous medium.  Preferably the mol. ratio of hydrazine hydrate to maleic anhydride and/or maleic acid is initially 1 : 2.  After the reaction the product is filtered off the filtrate may be refluxed with a further one mol. portion of hydrazine hydrate and one mol. of maleic anhydride or maleic acid.  Successive filtrates may be treated in this manner 4-5 times.  Where maleic anhydride is a reactant a neutral water-soluble salt of a metal such as sodium chloride is preferably added to the reaction medium. Examples are given.

Title: An improved counting device for over voltages
IPC: G01R19/165
Filed: 1943-10-16
Abstract: 566,645. Thermal instruments. LANDIS & GYR SOC. ANON. Oct. 16, 1943, No. 17042. Convention date, Nov. 7, 1942. [Class 37] In apparatus for counting current impulses of short duration, such as those resulting from atmospheric effects or switching operations on long lines, a fraction of the diverted current flowing through a diverting resistance is passed through a resistance arranged in a vessel filled with gas, the gas expanding under the influence of the heating which takes place and actuating a counting device through a flexible diaphragm. A heating resistance 1 is supported by current leads 12 passing through a glass foot 11 to which is fused a flange 10 connected to a corrugated metal extensible diaphragm 3. The extensible chamber thus formed is filled with an inert gas of low specific heat and is supported by a socket 13 with connecting pins 14. On the cover of the corrugated metal tube 3 is arranged a pin 15 which transmits the movement of the diaphragm through a lever 16, toothed segment 17, and gear-wheel 18 to a counting mechanism 19. A second diaphragm 20 compensates for the effect of ambient temperature on the diaphragm 3. The pin 15 may, alternatively, close a contact in the circuit of a relay which operates the counter. In another arrangement the counter is operated by clockwork, operation of the pin 15 releasing a wheel in the train and permitting it to make one revolution, which causes the counting train to be advanced by one figure. A protective surge diverter 6, Fig. 1, is connected between the overhead line 5 and earth. In the earth lead is a resistance 8 across which the heating resistance 1 is connected. The resistance 8 may be such that the voltage across it does not rise with the current strength according to a straight line law, so that the heating resistance 1 is protected against excess current. A choking coil 9 is connected across the resistance 8, its inductance being so chosen that its impedance is high for the surge discharge, but small for the follow current. The apparatus may be combined with a recording arrangement for the determination of the approximate strength of the diverted current, the movement of the diaphragm being utilised for measuring the current.

[Class 39 (i)] A device for producing X-rays in great quantity for short periods comprise a mercury or other cathode liquid at the operating temperature and means capable of supplying current to the device at a greater rate than it can be transmitted by the cathode during the initial discharge period, thus producing a high potential drop between the cathode and anode. Fig. 1 shows an arrangement in which a condenser 17 can be charged to a high potential and is discharged through the tube 10 when the starting-electrode 22 in the latter is activated by the condenser 23 and switch 27. The tube 10 is provided with a mercury pool cathode 14, which is preferably cooled to or below 0‹ C. by a coil 35, and a tungsten anode 11 on a molybdenum lead 12. The starting-electrode 22 may be replaced by a spark gap in series with the condenser 17 and tube 10, or the starting-electrode and spark gap may be combined. Fig. 6 shows a tube in which the cap 56 through which the anode lead passes is screened from the cathode by a cylinder 62 forming part of the lead. A shield 68 is interposed between the starting-electrode and the anode. To prevent darkening of that part of the tube through which X-rays pass by sputtering from the anode, the tube is formed with an extension 71 with a window 70 for the rays at the end of it.

Abstract: 497,845. Bushes for bung holes. MYERS, J., and WILLIAMS, M. W. June 25, 1937, No. 17766. [Class 21] [Also in Group XXII] The overlapping portions of a flanged bushing and the apertured wall of a container, such as a drum, are secured together throughout an annular zone surrounding the opening by a single continuous weld confined between the opposed surfaces of the overlapping portions and produced in one operation. One or more annular current localizing projections 52 may be made in the flanges 51 and the edge of the opening in the wall 48 may be turned up at 55. Alternatively, the projections may be formed on the container wall or on both parts. The projections may be formed either on the inner face of the parts only or by stamping so that a ridge is formed on the inner face and a corresponding depression in the outer face. In a further modification, an annular strip or wire ring may be placed between the parts. In another form, localization of the current may be effected by turning down the periphery 82, Fig. 6, of the flange and bending up the edge of the opening of the container wall at 85. The wall may be embossed round the opening either above or below the flange, or the flange may be formed as at 101, Fig. 8, on the upper end of the bush. The projections may be of polygonal form when polygonal flanges are used. The bushes are formed at their upper ends with a beaded edge 53 or 103. Welding is effected by a pair of ring electrodes 26, 27. Specification 391,050 is referred to.
