Title: Improvements in or relating to low pressure gas filled thermionic valves
Inventor: ALGAR LESLIE ERNEST
IPC: H01J17/56
Filed: 1958-03-20
Abstract: 855,998. Thermionic valves. M-O VALVE CO. Ltd. March 20, 1959 [March 20, 1958], No. 9028/58. Class 39(1). A low pressure gas-filled thermionic valve includes an anode, having a substantially planar portion 9, and a box-like second electrode 3 which effectively encloses the planar portion of the anode except for an opening through which passes the anode lead. The gap between the periphery 22 of this opening and the adjacent part 18 of the anode is closed by an electrical insulator 5, 6, at least part of which is an accurate fit with respect to the contiguous parts of the anode and electrode 3, the connections at 7 and 8 being such as to permit relative movement between the insulator and the anode and electrode 3 while still maintaining closure of the gap. The arrangement is such that in operation the lengths of the electric lines of force between the anode and electrode 3 are all of the same order of magnitude and that an appreciable movement of the insulator relative to the anode and electrode 3 may occur without altering the lengths of the lines of force in the vicinity of said connections. As shown the molybdenum anode disc 9 is soldered to a copper boss 10 which is in turn bolted and soldered, by means of a tin washer which melts and resolidifies during processing of the valve, to a disc 12. A cooling fin may be screwed on to the tube 14. Three sleeves 4, 5, 6, two of which constitute the aforementioned insulator and the third of which serves to support the box-like control electrode 3 by means of a steel wire ring 30 threaded through lugs 28, are formed integrally with the envelope 1 of borosilicate glass. Shields 31 and 32, in contact with the control electrode and anode respectively, inhibit the possibility of long path discharge breakdown occurring between the control electrode and anode through the sleeves 5, 6 or the envelope. The control electrode comprises cup-shaped portions 19, 20 formed with radial slits 27 and a central aperture 25, respectively, through which the discharge passes, the slits 27 being too small to allow penetration of electric lines of force therethrough. Parts of the side wall of cup 19 are formed by metal gauze to permit gas to enter the interior of the cup. The thyratron is filled with hydrogen at a pressure of 0À4 mm. of mercury.
Patent GB-596875-A (GB)
Title: Improvements in or relating to the manufacture of magnets
IPC: C04B35/26
Filed: 1945-04-11
Abstract: A permanent magnet having high coercive force and remanence, is made by the agglomeration of a fine powder obtained by the simultaneous precipitation of iron and cobalt salts from a solution, the decomposition of the salts into oxides by heat at a temperature less than 600 DEG C and their oxidation in contact with an oxidising atmosphere.  The magnet or the powder may be reheated to temperatures less than 400 DEG C, if desired, in a magnetic field.  To facilitate mixed crystallization, salts, such as formates, acetates and oxalates, are selected in which the iron is in a ferrous condition. To prevent the salts assuming a ferric condition, oxidation is stopped by oxidizing the outer layer before decomposition.  In one example a boiling solution of iron and cobalt formates containing iron and cobalt in the ratio 2 : 1 in dilute formic acid, is cooled so that a compound formate is precipitated.  It is dried, heated to 400 DEG C to achieve decomposition and the beginning of oxidation and air is passed over first at 1 litre/gm/hr and then at 4 litres/gm/hr and the powder obtained is agglomerated under pressure.  In other examples formates having a Fe, Co ratio of 6 : 1, and oxalates and acetates having Fe, Co ratios of 2 : 1 were treated as in the preceding example.  Figures of remanence and coercive force before and after heat and magnetic treatment are given.  Specification 590,392, [Group XXXV], is referred to.

Filed: 1941-07-18
Abstract: 549,741. Purifying water. STERN, R. July 18, 1941, No. 9079. [Class 46] [Also in Groups XVIII and XIII] A boiler 1 is connected by pipe 2 to an injector 4 operated by the feed water so that deposited sludge is drawn from the boiler and forced through spiral passages 8 into a vessel 6. The sludge is deposited in the bottom, from which it may be withdrawn, and water returns through pipe 10 and steam condenser I to the boiler. Steam is discharged from a nozzle 21 against a plate 1-7 which thereby receives a positive electric charge. The plate is connected through, a condenser 18 to earth, and through a spark gap 15, 16 to an electrode 14 from which the charge passes into the water and modifies the character of the contained salts that they are deposited in the boiler as sludge and not as scale. Instead of the spark gap 15, 16, a neon tube may be used. A modification is described in which current is obtained from a rectifier valve for treating the water, and the sludge is deposited by electrophoresis.

Abstract: 1,224,434. Ventilators. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 21 Feb., 1969 [27 Feb., 1968 (3); 21 Aug., 1968; 1 Nov., 1968], No. 9608/69. Heading F4V. A ventilator having a motor driven fan has movable shutters and control mechanism for opening and closing the shutters. Clutch mechanism is provided in the drive between the motor and the shutters whereby motor operation sensing means causes the clutch to engage to open the shutters and the clutch is disengaged when the shutters are fully open whilst the motor continues to drive the fan. The shutters remain locked in the open position. On stopping of the fan motor the sensing means causes release of the locking means and the shutters close under spring action. In all embodiments described, shutters 212, Fig. 16, are pivoted to a bar 213 and urged by a spring 214 to their closed position and are opened by a sheathed cable 215 wound upon a reel forming part of a gear mechanism driven from the motor via the clutch. The motor operation-sensing means may comprise an electromagnet which in one embodiment, Fig. 16, attracts a lever 208 thereby inserting a pinion 219 between a driving gear 217 on the motor shaft and gear which winds up the cable 215. A ratchet member 229 engages a projection 224 to retain the shutters open and is withdrawn by the lever 208 when the motor is stopped. In another embodiment (Fig. 3), the electromagnet attracts spring fingers (27), (28), one of which interposes a clutch member into the drive between the motor and a gear train which winds up the cable attached to the shutters and the other forms locking means retaining the shutters in open position. In another embodiment, (Fig. 12), energizing the electromagnet (118) causes levers (131), (124) to swing anticlockwise and an intermediate gear to be interposed in the gear train driving the shutters so that the latter are opened. When the shutters are fully open the levers and associated pawls are tripped to lock the mechanism in the shutter open position. When the fan motor is switched off the mechanism is again tripped and the shutters close by spring action. In an embodiment which dispenses with the electromagnet, Fig. 21, the motor operation sensing means comprises an element 316 coaxial with the motor shaft 308 and having an inclined slot 317. engaged by a pin 320 in shaft 308. Rotation of the motor shaft 308 causes axial movement of element 316 whereby a pinion 318 on the element engages a gear train which winds up the shutter cable 312. Lever and pawl mechanism lock the shutters in the open position and the locking mechanism is released when the motor stops. The pinion and intermediate gears could be replaced by friction wheels.

Abstract: 1449971 Telescopic actuators H JUNGHEINRICH & CO MASCHINENFABRIK 4 March 1974 [17 April 1973] 9648/74 Heading F1D To expand the double-acting telescopic actuator shown in Fig. 1 pressure fluid is admitted through an inlet 4 to push out piston 6 and cylinder 5 relative to cylinder 1. This causes fluid to be displaced by piston 6 from a chamber 10 through ports 36 into a chamber 35, thus pushing out piston 21 and piston-rod 20. Fluid displaced by the piston 21 from a chamber 26 flows out through ports 34, the interior 31 of the piston-rod 30 and a port 29. Contraction of the actuator is effected by admitting fluid through the port 29 and exhausting through the port 4. Chambers 10 and 35 contain a constant volume of fluid, any losses being made up through a spring-loaded check-valve 16. Venting devices 32, 33 allow the escape of air during initial charging of the actuator. This arrangement ensures that all sections of the actuator expand simultaneously. Fig. 2 shows an embodiment in which fluid admitted through a port 4' acts on pistons 6', 21', to move them to the left and fluid is exhausted from chambers 10' and 26' through a port 29' via ports 43, 44, 34'.
