Abstract: 298,296. Mavrogenis, A. July 21, 1927. Vacuum tubes.- A three electrode valve, a rectifying valve, and a smoothing valve are contained in a single envelope so as to enable an alternating current supply to be rectified for energizing the anode of the three electrode valve, the cathodes for all the valves being heated by current from the same mains. All the connections betweern the valves are mounted in the envelope, and a condenser and resistance are arranged in the neck. As shown in Fig. 1, the three electrode valve consists of an anode 33 and a grid 37 surrounding a cathode 22, the rectifying valve consists of a U-shaped anode 27 surrounding a cathode 21, and the smoothing valve has a U-shaped anode 26 surrounding a cathode 20. The cathodes 20, 21, 22 consist of oxide-coated nickel or tungsten tubes mounted on quartz tubes 18, Fig. 2, and spaced by enlargements 19, and the heater consists of a single V-shaped helical filament 16. The anodes 26, 27 are carried by fork-shaped supports 28, 29. The grid consists of a wire wound around double rods 38. A condenser 6 is mounted in the neck, and consists of rectangular sheets 7, 8, Fig. 4, of 'metal foil separated by mica and with alternate ends pressed or folded together, the edges of the sheets being bevelled to facilitate mounting in the neck. The outer edges are insulated by mica 12. A carbon resistance 'block 13 is mounted on one side of the condenser. The valve has four contact pins. The circuit arrangement is shown in Fig. 6. The filament 16 is connected through contact pins 44, 51 and a resistance 60 with alternating current mains 61, 62. The pin 51 is connected with the anode 27 of the rectifying valve, the cathode 21 of which is connected with the anode 26 of the smoothing valve. The condenser 6 is connected between the anode 26 and the pin 44. The cathode 20 of the smoothing valve is connected with the anode 33, and the resistance 13 is connected between the anode 33 and the pin 44. The input circuit is connected through contact pins 49, 47 with the cathode 22 and grid 47, and a transformer 58 is inserted in the output circuit. The minimum rectified voltage supplied by the rectifying valve is greater than the saturation voltage of the smoothing valve, so that unvarying current is supplied to the anode 33 and resistance 13. In a modification the supply voltage to the anode 27 is increased by a transformer.

Title: Improvements in friction drive screw presses
IPC: B30B1/22
Filed: 1951-08-21
Abstract: 705,710. Screw presses. TAYLOR & CHALLEN, Ltd., and CHALLEN, J. B. Aug. 18, 1952 [Aug. 21. 1951], No. 119652/51. Class 87 (2) A friction-drive screw press comprises a flywheel 6 adapted to be driven alternately by friction wheels 8, 9, arranged on a movable shaft 10, means being provided for bringing the flywheel to rest at the top of the upstroke. When lever 12 is depressed friction disc 8 is moved to contact the flywheel 6 through the action of links and levers 15, 19, 21, 23, 24, 25, 27. The lever 12 is held down against its bias until the end of the downstroke. When released it rises and causes the other friction disc 9 to engage the flywheel and thus initiate the upstroke. At the end of the upstroke the flywheel 6 strikes a brake shoe 28 which, through the medium of levers 29, 31. 15, disengages the friction wheel 9 and forces the lever 12 down against a stop 43, Fig. 4, which prevents the lever descending an extent sufficient to cause engagement of the friction disc 8. Levers 31 and 15 interengage by means of a pin-and-slot connection 33 whose setting, adjustable by means of hand wheel 32 determines the point of contact between the flywheel and the brake shoe. A certain amount of lost motion, against springs 38 is permitted between the brake shoe and the lever 219 in such a manner that, after the lever 29 has been locked by the action of the step 43, the shoe 28 may continue to rise until the flywheel 6 has been brought to rest The lever 12 is in two parts hinged about a vertical pin 40 which enables the outer part 12a to swing outwardly and released from the step 43 when it is desired to start the press by depressing the lever.

IPC: E05F15/00
Filed: 1968-04-26
Abstract: 1,206,881. Pressure-actuated sensitive door edge safety device. COMPAGNIE GENERALE FRANCAISE DE TRANSPORTS ET D'ENTREPRISES. 26 April, 1968, No. 19902/ 68. Heading E2M. [Also in Division H1] An electrically controlled door for e.g. a tube train has an edge sensitive to the pressure exerted on it by an obstruction during the closing of the door, thereby causing the door to open and reclose only after a predetermined time. The sensitive edge consists of a resilient cushion 19, attached to the door 18 so as to define a tubular inner cavity 20 sealed from the atmosphere. Both ends of the cavity are sealed by resilient plugs 21 and 22. A pressure sensing device 23 is sealed in a bore in the plug 21 and comprises a body 24 containing a bore 25 in which a piston 27 slides. As the doors close, if the sensitive edge comes into contact with an obstruction it undergoes deformation and the air in the cavity drives the piston towards the top of the bore thus forcing contact blade 31 into contact with blade 31a and thereby closing contact 32 in the electrical circuit (Figs. 1 or 2, not shown) which controls the door operation. This re-establishes supply to the electrically operated valves, (15) which control the admission of hydraulic fluid to the cylinders which actuate the doors, through a timed relay (48) so that the door opens but closes again after a predeterminedtime. The control system for the doors may be linked to the braking system and gearbox of the vehicle to which they are attached. The vehicle doors can be brought under the manual control of the driver or conductor of the vehicle.

Title: Improvements in or relating to the manufacture of materials comprising artificial resins
IPC: C08L1/02
Filed: 1936-07-20
Abstract: Consists in employing as binder a dispersion e.g. aqueous, or dispersions of components which together produce artificial resin formation, one component giving resin formation with aldehydes, e.g. phenol or a homologue, aniline, urea, casein, gelatine or glue, and the component reacting therewith having a higher evaporation point than the dispersing agent, the binder and fibrous material being brought together in the open atmosphere, followed by condensation and polymerization.  The second component may be a compound splitting off aldehyde, e.g. hexamethylenetetramine or aldehyde-ammonia, or a compound such as sulphur adapted to produce resin formation with phenol &c.  The dispersion may consist of a solution, emulsion, or fine or coarse suspension; water is advantageously employed as dispersing agent and the components may be separately dispersed in which case different liquids, e.g. water and alcohol may be employed. Condensation may be assisted by addition of alkalis or catalysts. In examples, (1) dry mechanical wood pulp is introduced into and well suspended in an aqueous solution of formaline and ammonia neutralized, e.g. with aluminium sulphate, cresol is added and the mixture well stirred and formed into a web on a paper machine; the web is heated to 80-100 DEG  C. and slowly dried and is finally hardened in hot presses, the pressure being insufficient to destroy porosity; (2) dry paper sheets are immersed in an aqueous solution of hexamethylenetetramine and phenol, heated to 80-90 DEG  C., slowly dried, superposed and pressed at 120-140 DEG  C.; (3) porous shaped bodies of feltable organic fibres are immersed in an aqueous suspension of cresol and sulphur, heated to 80-90 DEG  C., slowly dried and heating continued to 120-140 DEG  C.  The Provisional Specification refers also to the impregnation of porous shaped bodies of asbestos fibre or slag wool. Specification 6363/12, [Class 2 (iii)], is referred to.
