The molar ratio of lutetium silicate to yttrium silicate is larger than 0À05 but smaller than or equal to 4. The phosphor exhibits short afterglow and luminesces from U.V. to shorter visible wavelengths as in the Fig. (not shown). Emission may be electrons or U.V., e.g. 3650 and 2537. The phosphor material is prepared by mixing lutetium oxide, silicic anhydride and yttrium oxide with cerium compounds (e.g. cerous chloride, CeCl 3 .7H 2 O, hydroxide or nitrate), baking in a reducing or oxygen free atmosphere, followed by a second baking after quenching. Specific mixing proportions and baking temperatures and times are given. Carbon powders may be spread on the surface of the mixed mass during baking. Excitation by a 10 KV, 1 ÁA/cm<SP>2</SP>. electron beam is exemplified. Table II indicates peak luminescence and long wavelength limits.

Abstract: 776,838. Pipe couplings. SHELL RESEARCH, Ltd. Oct. 24, 1955 [Nov. 11, 1954], No. 32665/54. Class 99(1) In a pipe union, wherein one pipe 2 is provided with a valve 3 normally closed by pressure fluid and/or a spring 4 and the other pipe 1 carries a projecting plunger 14 that is adapted to open the valve 3 on or after connecting up the pipes, comprising a quick-release device for coupling the pipes and a manually - operable member 13 capable of movement into one of two positions so that (1) coupling and uncoupling can only be effected when the member 13 is in one of the two positions and is otherwise prevented by the member 13 impeding manipulation of the quickrelease device, and (2) on coupling the pipes the member 13 when in the first position renders inoperative the plunger 14 but in the second position causes or allows the plunger to open the valve. The pipe 2 connected to a gas container houses a resilient gasket 6 whilst the valve 3 has a washer 5 and an extension 22; the pipe 2 is formed at its upper end with bayonet slots 18. The other pipe 1 carried by a pressure-reducing valve accommodates the plunger 14 which has an extension 23 disposed in a passage 15; bayonet pins 17 are carried by the pipe 1. The plunger 14 is retained within the pipe 1 by shoulders co-operating with a corresponding part, in the passage 15 and a spindle 7 passing transversely across the passage 15, the spindle embodying a flat 12 and a handle 11 with the lug 13 thereon. The bayonet connection may be replaced by quick-pitch threads or devices depending upon spring-urged catches or bolts or interengaging members moved by cam action, not shown. The lug and spindle may be carried by the pipe 2 whereupon additional cam and spring means, not shown, are provided for the actuation of the plunger; the positions of the bayonet pins and slots may be interchanged. With the handle 11 transverse to the pipe 1 the flat 12 is opposite the end of the plunger 14 and the lug 13 is remote from the bayonet pins 17 so that the latter may be engaged with the slots 18 to connect the two pipes whereupon the pipe 1 will seat in the gasket 6 whilst the extension 22 abuts the extension 23 and causes the plunger to approach or engage the flat 12, the valve 3 remaining closed. Upon turning the handle 11 through 90 degrees the curved surface of the spindle 7 adjacent the flat 12 acts as a cam and forces the plunger 14 downwards hence opening the valve 3; the gas path through the pipe 1 is comrpised by the space between the passage 15 and both the plunger 14 and spindle 7 in the area of the flat 12. To close the path through the coupling the handle 11 is turned back through 90 degrees. With the handle 11 in the position shown it is impossible to couple the pipes since the lug 13 will engage the outer edge of the pipe 2 and prevent the pins 17 from fully entering the slots 18; similarly the lug 13 prevents the valve being opened until thepipes are completely connected.

Projections 20 on the hub limit the inward movement of the links 12. The material is fed from a hopper 16 at the side of the casing, and the leading ends of the stones 7, 8 are cut away or bevelled at 18 to admit the material between the grinding-surfaces. The cover 17 may be connected to a fan, and the aperture 4 may be covered by a screw instead of by the plate 5.

Abstract: 752,641. Exhaust silencers.CALABRESI, G.. Nov. 12, 1954 [Nov. 13, 1953], No. 32901/54. Class 7(2) Exhaust gases are admitted to an expansion chamber 1 and discharged therefrom through a valve 11, or a movable baffle which is opened by the pressure of the exhaust gases, the valve being subject to the action of two springs 14, 18 which act in opposition to one another and the strength of at least one spring being adjustable. As shown in Fig. 1, sleeves 5, 6 of the same or different diameters and partly inserted in the exhaust pipe 3, are provided with cross-bars 7, 8 each apertured to receive a freely movable rod 10 carrying the valve 11 and a spring-actuated valve 12. The valve 11 is guided in the sleeve 5, the spring 14 bearing against an adjustable abutment 15 on the rod 10 and the springs 17, 18 bearing against the cross-bar 7. The valve 12 is rigidly connected with the rod 10 and acted upon by a spring 20. Since the springs 14, 17 and 18 overcome the pressure of the spring 20 the valve 12 closes the sleeve 6 when the engine is at rest and the valve 11 is slightly open. The valve 12 is opened by gases flowing into the expansion chamber 1 while the valve 11 is moved by the rod 10 and the action of the spring 14 to the closed position, the valves subsequently returning to the initial positions thereof so that the gases escape through the valve 11. Baffles 21 are arranged in the casing 2. In a modification, perforated baffles 39. 41 and 42, Fig. 4, are attached to a rod 35 movably guided in a cross-member 28, attached to a widened part 24 of a connector 22 secured to a chamber 26, and a sleeve 29 carried by the cross-member encloses opposed springs 37, 38 separated by a perforated disc 36. The compression of the stronger spring 38 is adjusted by the cap 31 which is locked by a ring 32.
