Title: Phosphor devices
IPC: C09K11/77
Filed: 1975-03-07
Abstract: 1525303 Luminescence and electroluminescence DEFENCE SECRETARY OF STATE FOR 5 March 1976 [7 March 1975] 9664/75 Heading C4S A device includes a visible light emitting phosphor formed of a pentaphosphate compound XP 5 O 14 , where X is a trivalent metal ion, and luminescent sites in the matrix. The luminescent sites may be the sites of the ions X for X ions of Eu or Tb, or X may be non-luminescent in the visible region, and the sites provided by dopant ions, in which case X ions may be Y, Yb, or Pr, and the dopant ions may be Tm, Er, Eu, Tb, or a mixture of Mn and Sb. The matrix may be single crystal, polycrystalline or glass form, and the luminescent ion sites may be in high e.g. stoichiometric, concentrations. Preparation is detailed utilizing heating of oxide(s) with orthophosphoric acid. The phosphor may be a coating 11 on epoxy encapsulant 9 around an infra-red emitting PN device. The coating comprises a solid solution of about 80 to 99% by wt. of, for example, ytterbium pentaphosphate which absorbs the infra-red energy which is transferred by one or more transfer mechanisms to a second visible light emitting pentaphosphate. Coating 11 may be applied as a paste of pentaphosphate powder and a solvent such as nitrocellulose in butyl acetate. The phosphor may be used as a c.r.t. screen layer (13b) (Fig. 2, not shown) deposited as above and covered by alumina layer (13c), or a phosphor (15a) (Fig. 3, not shown) such as TbP 5 O 14  or EuP 5 O 14  may be used in an inert gas discharge tube, low or high vacuum. Phosphor (15a) may be a mixture to produce white emission. The phosphor may be used in a dot matrix display panel having Ne filling for example. An electroluminescent device (Fig. 4, not shown) includes EL layer (22) of a pentaphosphate phosphor in a binder such as p.v.c., between tin oxide and Al electrodes, to which a 500 to 1000 Hz voltage is applied. The phosphor may alternatively contain conducting particles such as Cu, without a binder, and be formed to produce a narrow light emitting region energizable by unidirectional voltages. In an infra-red image converter using several stages of photocathodes and phosphors, the final screen may be the pentaphosphate phosphor. In an X-ray image intensifier using a photocathode both phosphor screens may be a pentaphosphate. In an infrared quantum counter, the pentaphosphate is simultaneously exposed to a D.C. laser output and the infra-red beam to be detected. The infra-red beam may be modulated and the output phase detected. Internal excitation mechanisms in the pentaphosphate are discussed.

Title: Improvements in fluid transmission gears
IPC: F16H39/36
Filed: 1944-05-23
Abstract: 586,522. Rotary engines. BEST, W. G. May 23, 1944, No. 9912. [Class 110 (ii)] [Also in Group XXIX] Internally-meshing engines and pumps of the type shown are used in a fluid transmission with liquid or gas as the working medium. Fig. 5 shows a mechanism for driving a motor cycle and includes a pump W, driven by an engine, supplying oil to a gear X coupled to the driving wheel of the cycle. In starting up, a valve 20 is closed and a valve 19 opened so that oil circulates from a reservoir 14x, through a pipe 17 and passages to and from the pump W. The oil flow to the gear X is regulated by the opening and closing of valves 19, 20. To use the gear as a brake, the valve 19 is fully opened and 20 gradually closed. The valve port 18x is triangular in section. Figs. 9. 10, 12 show a motorvehicle driving mechanism in which gear motors drive each half-axle 23 splined to tubular extensions 24 provided on discs 25. These discs have extending teeth 10 meshing with teeth 11 on the pinions, the two motors being separated by a diaphragm 31 carrying arcuate members 32. Power is supplied by a shaft 33 to a pump Z which is connected to oil ducts 35, 36. The admission of oil, or release thereof, from the circulatory system, is controlled by a valve 38, and running control by valves 38, 39. For reversing the direction of rotation of the drive, a valve 40, Fig. 12, is turned through a right angle to disconnect through passages 41, 42. When rotated to its new position, spiral passages 43, 44 cross connect ducts 35, 36. Any means may be used to actuate the valve spindles. The invention may be applied to other drives.

Title: Improvements in or relating to steroids and the preparation thereof
IPC: C07J75/00
Filed: 1952-04-21
Abstract: The invention comprises a sterol containing the nucleus <FORM:0726919/IV (b)/1> wherein X represents an aliphatic hydrocarbon radical, and the esters and ethers thereof, and a process for isomerizing a sterol containing homoannular conjugated double bonds with one of the double bonds at the 5,6-position, or an ester or ether thereof, which comprises heating said sterol in the presence of sulphur dioxide to form an isomer having rearranged double bonds in the nucleus.  It is preferable to carry out the above process in the presence of an organic base, e.g. pyridine, dimethylaniline or quinoline.  The reaction may be carried out at a temperature between 75 DEG  and 200 DEG  C. and/or in the presence of an organic solvent, e.g. an aromatic hydrocarbon such as benzene or toluene, a petroleum fraction such as hexane or a saturated cyclic compound such as cyclohexane.  At least 0.1 mole. each of sulphur dioxide and organic base based on the quantity of steroid reactant used, and at least 1 to 10 per cent by weight of steroid reactant used of a polymerization inhibitor may be employed in the above process.  Suitable polymerization inhibitors are hydroquinone and 4-t-butylcatechol. The process may be applied to form 6,8(14),9(11)-triene sterols from the corresponding 5,7,9(11)-trienes, and 6,8(14)-diene sterols from corresponding 5,7-dienes.  Suitable sterol reactants are ergosterol and dehydroergosterol and the esters and ethers of either compound. Isolated double bonds not within the cyclic structure of the steroid do not effect the course of the above process.  The C17-side chains attached to the ergosterol or dehydroergosterol type steroid nucleus may be varied in addition to variations at the C3-position, e.g. the 3-hydroxy group may be esterified with propionic or benzoic acid. The C17 position may contain a carboxyl, an acetyl or a saturated alkyl group or an oxygen atom.  In the examples isodehydroergosteryl acetate is prepared from dehydroergosteryl acetate, and isoergosteryl acetate is prepared from ergosteryl acetate and may be hydrolysed to ergosterol.  A maleic anhydride adduct is prepared by refluxing isodehydroergosteryl acetate and maleic anhydride in benzene. Ergosta-8(14)-en-3b -ol acetate is prepared by the hydrogenation with 3 moles. of hydrogen of isodehydroergosteryl acetate at low pressure in the presence of platinum oxide.  Specification 726,920 is referred to.

The fins may be mechanically clamped to the base portion at the other end. The terminals may be carried by a carrier strip and the fins may be preferably formed by punching a portion of said carrrier strip and bending it around said base portion of the terminal to form parallel fins extending on opposite lateral sides of the base portion. A process for manufacturing the electrical terminal is also disclosed.
