Title: Improvements relating to phosphors and methods of manufacture thereof
Inventor: MCGILL ERIC FREDERICK GEORGE
IPC: C09K11/56
Filed: 1964-02-27
Abstract: A method of preparing a phosphor comprises heating a finely ground phosphor base, e.g. zinc sulphide, with an activating agent, e.g. silver or silver nitrate, and at least 5 w./o. of a flux, e.g. magnesium ammonium chloride, for a sufficiently short time, e.g. up to 3 minutes and preferably 90 seconds, to produce a phosphor composed predominantly of particles not exceeding 1.5 micron in size, the phosphor base and the activating agent being composed of particles less than 1 micron in size.  The heating may be carried out in a thin-walled silica boat or tube, containing only a thin layer of phosphor, and inserted in a 1000 DEG  C. furnace in a nitrogen atmosphere.  The phosphor is then washed with water and finally sieved through a 200 mesh silk.

Abstract: 550,982. Electrically wound clocks; partlyelectromagnetic switches. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., RUSSELL. V. J. S., and MOSS, E. B. June 30, 1941, No. 8239. [Class 38 (v)] [Also in Group XVIII] When a clock runs down, a centrally-pivoted two-pole armature 10, which moves with the main driving spring 31, causes by means of a projecting part 26 the closing of contacts 14, 15 in the circuit to an electromagnet 11 which thereupon attracts a secondary armature 19 to maintain the contacts 14, 15 closed while the main armature 10 is attracted so as to restress the spring 31. At the end of the movement of the main armature 10, a projection 27 on it opens contacts 16, 17 in the electromagnet circuit so that the spring 31 again drives the armature 10 which in turn, through a ratchet mechanism 35, drvies the clock. A maintaining spring 30 keeps the clock running while spring 31 is being stressed. One of the contacts 16 may be carried by a bimetal strip 28 the heating coil 33 of which is in the electromagnet circuit, so that should the armature 10 fail to open the contacts 16, 17 they will open owing to the bending of the bimetal strip.

Abstract: 472,271. Sluice valves. ATELIERS NEYRET-BEYLIER & PICCARD-PICTET. March 19, 1936, No. 8291. Convention date, Jan. 4. [Class 68 (ii)] A sluice valve comprises a curved surface 1, the axis o of which is the axis of oscillation, and a platform 2 moving with it ; the pressure beneath the platform counterbalances the weight of the valve, and raises it as the upstream level rises, so increasing the flow in the downstream section. In modifications, a partition extends horizontally beneath the part 2 from the axis o to the inner surface of the part 1, forming a shallow chamber from which water may flow to a spill-chamber on the part 2. Alternatively, water may be led into it from a channel in the wall of the water course, or this channel may lead from the stream above the wall 3 to a weir in the downstream section. The part 2 may be sloped to prevent the lodging of mud &c. and in one modification its upper surface is exposed to atmospheric pressure only. A counterweight may be used with the platform.

The connections consist of a gear wheel 22 fixed to each type-wheel, a wheel 29 having the same number of teeth fixed to each setting-wheel, and intermediate gears 24. The wheels 27 are adjusted by hand, and indicia corresponding to the characters in printing position are viewed through apertures in a sighting bar 30. The type and setting wheels are aligned and locked in adjusted position by a bar 46 engaging the teeth on the wheels 24, the bar 46 being carried by blocks 45 adjustably fixed by screws 41 to a frame 38 secured to a manually rotatable shaft 34.

Title: Improvements in or relating to press-fitted, shrunk or like joints and to methods ofassembling and separating them

Abstract: 599,304. Assembling force fits; jointing. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Dec. 24, 1943, No. 8559/46. Convention date, Dec. 31, 1942. Divided out of 599,251. [Class 83 (iv)] Force and shrinkage fits are assembled or separated by forcing fluid from a narrow channel, between the joint surfaces under pressure sufficient to relieve metallic contact during relative displacement of the members. A sleeve 5, Fig. 1, for coupling shafts 1, 2 is first shrunk on the end of the shaft 1 in the position shown by dotted lines. The turned-down ends 3 of the shafts have a thin sealing ring 4 applied to prevent pressure fluid, such as oil, from penetrating between the shaft ends. A screwed connection is made at 8 of a source of pressure oi[ that is conveyed by a duct 6 to a channel 7 and the pressure is such as substantially to relieve metallic contact between the parts permitting the sleeve to be moved easily into the required position. As applied to a built-up crank-shaft, the pin 12, Fig. 2, has a taper surface somewhat shorter than the hole in the crank and an axial duct 6 in the pin leads to a central groove 7. The bore for the crank-shaft has an inclined groove 15 near one end forming a sealing lip 16. The whole assembly in this case is effected with the aid of the pressure oil. The inner race of a roller bearing may be similarly mounted on the tapered end of a shaft.

Abstract: 1479995 Valves KRAFTWERK UNION AG 28 Feb 1975 [1 March 1974] 8591/75 Heading F2V [Also in Division G3] A combined stop and blow off valve in a steam line from a steam generator has a valve member 6<SP>1</SP> connected to a piston 11 which is subjected in use to pressure from upstream of the valve seat via line 17 and throttle 16 on its upper surface 11 and from downstream of the seat via line 20 on its lower surface 13, the chamber above the piston being provided with a relief valve 15. Loss of downstream pressure in the line 5 causes a reduction in the force acting on piston face 13 so that the valve is closed by pressure on face 11. An increase in upstream pressure above a set valve causes relief valve 15 to open reducing the pressure on face 11 so that the valve is reopened by the pressure on the closure 6. In any embodiment valves 18 are opened momentarily to effect initial opening by pressure on the lower piston face 13. A restricted steam supply via valve 19 is provided to compensate for possible loss of pressure on piston face 13 by leakage. A three way valve (not shown) and a pressure drop measuring device (not shown) are described as being co-operative to open line 20 on detection of a major pressure drop in line 5. The valve 6 may form part of a pressurized water, nuclear reactor, steam generating system contained in a safety vessel 1 and concrete shielding 2 through which the live steam line 5 passes from the steam generator 4. External stop and safety valves 9, 10 are provided. The valve 6 shuts off line 5 if leakage occurs therefrom. If subsequently steam generator pressure becomes excessive valve 6 is reopened as the result of pressure release by valve 15. A container 23 is provided for collection of pressurized water in the event of a steam generator tube leak.
