Title: Improvements in or relating to surface coated phosphor particles
IPC: H01J29/32
Filed: 1966-11-30
Abstract: 1,175,040. Luminescent materials. DAI NIPPON TORYO K.K. 31 Aug., 1966 [12 July, 1966], No. 27877/69. Divided out of 1,168,074. Heading C4S. Rare earth oxyacidate phosphor particles have a surface coating of acidic oxide of B, Al, V, Ga, Ge, As, Nb, Mo, Sn, Sb, Tn or W. The coating may be applied by mixing preferably in a liquid medium the phosphor and the oxide or a compound which on heating forms the oxide, e.g. hydroxides, carbonates, sulphides and NH 4  oxyacidates. The mixture is heated causing the oxide to melt, some of the oxide may diffuse on to the surface of the phosphor particle reacting to form an adhering intermediate layer. The particles may be coated by mixing the oxide suspended in an aqueous or non-aqueous dispersion and the particles and then drying. An hydroxide can first be deposited by adding a solution of the salt to a phosphor suspension and adjusting the pH value then heating to convert the hydroxide to oxide. A further method is to add the oxide to a slurry comprising an aqueous phosphor suspension and PVA. YVO 4 : Eu is coated with GeO 2  by heating a suspension of YVO 4 : Eu in GeS 2 , water and HC1. Slurries containing the coated particles were prepared using PVA and NH 4  bichromate sensitizer for photoprinting colour TV screens.

Abstract: 1299560 Voltage multiplying rectifiers; systems depending on two sources FRANKE & HEIDECKE GmbH 15 June 1971 [2 July 1970] 27975/71 Heading H2F and H2H A power supply for an electronic flash apparatus comprises a pair of diode pump voltage doubling rectifiers having their output capacitors 9, 10 connected in series and their inputs connected directly to the supply mains 1, 2 and including a switching device (such as triac 22) connected between the common point of the output capacitors 9, 10 and the supply mains and arranged so that the apparatus may be operated from either high or low voltage supply mains depending on whether switching device 22 is open or closed. As described, when terminals 1, 2 are connected to 110V. A.C. mains, Zener diode 18 and transistor 21 are not conductive so that triac 22 is triggered on each half cycle, connecting the common point of capacitors 9, 10 to terminal 2 of the supply mains and giving a D.C. output of 622V. across terminals 11, 12. If terminals 1, 2 are connected to 220V. A.C. supply mains, Zener diode 18 breaks down, turning on transistor 21 which prevents triggering of the triac 22 and thus halving the multiplication factor of the circuit so that the output voltage remains unchanged. Triac 22 may be replaced by a relay or, as in Fig. 1 (not shown), by a manually operated switch.

Filed: 1925-11-09
Abstract: 259,782. Hunt, W. Nov. 9, 1925. Clutches, friction. -In a centrifugallyengaged clutch having manual means for preventing engagement, one or (preferably) more segmental shoes 5, carried by a transversely - divided spider or frame 2, coact with a driven drum 24, the pivot 4 at one end of a shoe being circumferentially guided, as by a slot 3 in the part 2, while the other end is acted on by a toggle-link 6, the length of which can be varied by an eccentric 8 or cam, crank &c., carried by a pivot 7 offset from the driving-shaft 1. Theeccentric &c. is turned to lengthen the link and apply the shoe by an arm 9, carrying a centrifugal mass 10, and normally held inwards by a spring (not shown), relative movement of the parts 9, 6 being restrained by a stop 16 when the eccentric &c. has reached its dead-centre position, further rotation of the arm 9 then. moving the shoe bodily in a circumferential direction, so that the link 6 increases the pressure by toggle action, this movement being assisted by the clockwise driving-torque and delayed by a dashpot 13. Except when the linkage or the clutchshoe facing is inherently elastic or the facing is spring-borne, sufficient range of shoe-movement for the dashpot to be effective may be allowed by giving radial play to the pivot 11 of the link 6 and interposing a spring 12 between the shoe and link. When the shaft speed falls, the arm 9 turns to withdraw the link 6 and disengage the shoe 5, further circumferential motion of which. tending to maintain engagement, is limited by a stop, e.g. the end of the slot 3. The shoe is finally withdrawn by a spring, which may be incorporated in the dashpot. A collar 19, provided with an incline 20, can be slidden manually to turn a lever 21 and block the arm 9 when it is desired to interrupt the automatic engagement.

Patent GB-445468-A (GB)
Title: Improvements in or relating to the manufacture of arsenic acid
IPC: C01G28/00
Filed: 1934-10-03
Abstract: Arsenic acid is obtained by reacting arsenious acid with oxygen or air in an aqueous medium at an elevated temperature under pressure in the presence of specified soluble or insoluble catalysts or mixtures thereof.  The insoluble catalysts are active carbon, silicic acid gels, a vanadium compound precipitated on a carrier, or platinum upon an asbestos or other inert support, whilst the soluble catalysts are iodine, iodides, or iodine compounds which yield free iodine in the reaction mixture, and salts of metals capable of existing in two valency stages such as copper, vanadium, manganese, iron, and chromium salts.  A mixture of an insoluble and soluble catalyst, for instance of active carbon and potassium iodide, is preferably used, and the reaction may take place at 130--140 DEG  C., under a pressure of 60--70 lbs. per sq in.  The process may be carried out as a batch process in a steam-heated pressure vessel or continuously by pumping a suspension of arsenious acid which may contain a soluble catalyst over an insoluble catalyst in a reaction tower into the base of which steam and compressed air are continuously introduced.  The aqueous medium may contain a wetting agent and/or a foam abating agent such as a sulphonated oil.  Specification 255,522, [Class 1 (iii)], is referred to.  According to the Provisional Specification, any catalyst may be used.

Abstract: 777,737. Statistical apparatus. ADRACTAS, J. Dec. 31, 1954 [Oct. 6, 1954], No. 28787/54. Class 106 (1). In card sorting apparatus wherein the cards have projecting teeth on their lower edges which rest on resiliently supported selector bars, selection is effected by depressing a combination of selector bars equal in number to the number of teeth per card (three in the embodiment shown), so that the selected card or cards move downwards under gravity. The selected cards are then ejected upwardly by spring biased ejector bars when they are suddenly released by snail cams. The Figures show a device for selecting any card numbered 0-999. Selector buttons 4, Figs. 5, 6 for units, tens and hundreds, respectively, are adjusted along a guide shaft 11 to the card number desired, whereby corresponding eccentrics 13 movable with the selectors 4 are positioned over the forward ends of corresponding selector bars 2. Each selector bar 2 is pivoted at its rear end at 5 and is linked at 6, at its mid point, to an upper bar 1 spring supported at both ends as at 3, the cards resting transversely across the upper bars 1. After the buttons 4 have been adjusted, as above described, the shaft 11 is rotated through one revolution, e.g. by a crank-handle, Fig. 8 (not shown), whereby the three selected selector bars 1, 2 are depressed by the three eccentrics 12 and the cards so selected move downwards under gravity. The outer pairs of bars 1-2, Fig. 7, which function as ejectors, are depressed by snail cams 16 on shaft 11 as the selection is made, and when the selected cards reach their lowermost position, the snail cams suddenly release the ejector bars which under the action of their springs 3 eject the selected cards above the remainder of the stack, the selected cards being held in their raised position by spring detents secured to the casing, Fig. 12 (not shown). Instead of two outer ejector bars, a single ejector bar centrally disposed of the selector bars may be used. The cards may be held in individual metal frames, in which case the frames are provided with the teeth.
