Patent PT-93731-A (PT)
IPC: D06M23/12
Filed: 1990-04-11
Abstract: An effective amount of perfume/cyclodextrin complex is applied to fabric that is preferably at least partially wetted. A preferred method applies said complex to said fabric in an automatic laundry dryer. The perfume/cyclodextrin complexes are preferably incorporated into solid, dryer-activated, fabric treatment (conditioning) compositions, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials, including those materials that are commonly associated with "freshness" can be applied to the fabrics in an effective way. Clay provides protection for said perfume/cyclodextrin complexes, especially when certain materials like some nonionic fabric softeners and/or fatty acids are present and in contact with said perfume/cyclodextrin complexes.

Inventor: DUNNE STEPHEN TERENCE
IPC: B05B15/00
Filed: 1991-03-21
Abstract: A metered dose inhaler comprises a piston (3) which is mounted in a cavity (2) within a body (1), and is urged by a pre-loaded spring (6) into a reduced cross-section pressure chamber (4). The piston (3) may be loaded by means of an actuating rod (31) having a handle (32), and may be latched in a loaded position by a latching means (33). A liquid drug (e.g. in aqueous solution) is contained in a collapsible bag (10). Metered quantities of the drug are successively presented in the pressure chamber (4), and then subjected to a sudden and great increase in pressure, to eject the liquid drug through an atomising head (22), to reduce it to a fine atomised spray of small mean particle size - for example, less than 30 micrometres. Non-return valves (13 and 23) control the flow of liquid through the device. The sudden pressure pulse is caused by releasing the spring loaded piston (3), upon depressing an actuating button (35) connected to the latching means (33). <IMAGE>

Abstract: 1,225,951. Handling radioactive material. EUROPEAN ATOMIC ENERGY COMMUNITY. 10 Jan., 1969 [12 Jan., 1968], No. 1691/69. Heading B4Q. Radioactive samples (not shown) are stored in tubes 8 closed by plugs 10 provided in a concrete block 9. A hot cell 1 made of lead is open at its lower side and movable on tracks 2, 3 having roller bearings 11 over the mouths of the tubes 8, the cell being driven by cables 23, 24 by a motor-gear unit 20, 21 so that the desired tubes may be located within the space enclosed by the cell. The cell 1 has a window 5, a crane 18 controlled by hand wheels 6, a pair of manipulators 4, an airlock 7 for introducing samples and an air filter 17. In use, the crane 18 lifts the plug 10 and attached sample from the selected tube 8, a manipulator 4 removes the sample and the crane replaces the plug.

Abstract: 1,226,228. Electro-deposition of alloys. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 2, 1969 [May 7, 1968], No.22553/69. Heading C7B. An alloy consisting of two metals having standard electrode potentials which differ by at least 0À6 volts is electro-deposited from an electrolyte to which ions of the metal having the lower cathode potential are continuously added from a separate vessel which contains a suspension of a sparingly soluble salt of said metal, the salt having a solubility product in water at 25 C. of not more than 10<SP>-6</SP>. The suspension of the sparingly soluble salt may be separated from the electrolyte in the cell by a porous partition, e.g. it may be contained in a porous vessel submerged in the electrolyte, so that diffusion takes place therethrough, or the electrolyte may be cycled through the vessel containing the suspension, to become replenished thereby. The present method may be used to deposit a nickel/silver alloy using an electrolyte of nickel sulphate or nickel sulphamate, which may also contain an amidosulphonate, and a suspension of silver thiocyanate; which coating may be applied to parts to which semi-conductor crystals are to be attached by means of lead-tin or lead-tinsilver solder.

Abstract: 1,226,942. Gas turbine plant; engine stop gear. JOSEPH LUCAS (INDUSTRIES) Ltd. May 16, 1968 [March 2, 1967], No.9878/67. Headings F1G and F1K. [Also in Division F2] Series connected throttle valves 19, 20 in an automatic fuel control system feeding a gas turbine, each comprise a spring-loaded body 33 having a closure member 32 co-operating with seat 31, and a piston portion 34 subjected on its upper and lower faces respectively to outlet pressure and the pressure existing in pipes 36, 39 which are connected to the input side of pump 10 by a pressure drop unit 21 and speed responsive valves 26, 27, the piston 34 being provided with a restricted passage 35 whereby the pressures at opposite sides of the piston can be equalized, to permit the valve to close under the action of spring 38, when the pressure in pipe 36 or 39 is cut off by operation of speed sensitive valves 26, 27 or emergency stop valve 40.

Abstract: 1,232,258. Delimbing and topping trees. BELOIT CORP. 2 Oct., 1968 [25 Oct., 1967], No. 46744/68. Heading B5L. [Also in Divisions A1-A3] Apparatus for delimbing trees comprises a head 50, Fig. 1, delimbing blade means 52, 54 mounted on the head for movement relative thereto, means for moving the head along a tree to be delimbed, means connected to the head and the moving means for developing a fluid pressure due to movement of the moving means, and means responsive to the fluid pressure to move the blade means. In the apparatus described a tree T which has been gripped by jaws 32, 34 and cut by blades 36 is lifted by a boom assembly 16 on to a platform 14 where it is held by jaws 40, 42. The head 50 is then drawn upwardly along the length of the tree to delimb it, the movement being effected by a cable 72. As shown in Fig. 6 the cable 72 is connected to rods 104, 106 provided with a piston 108 which slides within a cylinder 110 carried by the head 50. As the head 50 is pulled downwardly by cable 72 pressure is exerted on a fluid in the lower part of the cylinder 110 so that a fluid flow is created in conduits 112, 116, 120, 122 and 134. Such flow results in withdrawal of pistons 63 in cylinders 62, 64 so that the delimbing blades 52, 54 are pivoted away from each other. The flow in conduit 134 causes tree topping blades 86, 88 linked to the piston 139 of a cylinder 136 and also carried by the head 50 to be moved to their inactive position shown. The movement of pistons 63 and 139 also causes fluid flow in conduits 130 and 140 which results in the storage of fluid energy in accumulators 132, 152. When the head 50 is subsequently pulled upwardly, the piston 108 is raised in the cylinder 110 so that the fluid energy stored in accumulator 132 is released to move the delimbing blades towards each other as they move up the tree. When the blades reach a certain position, corresponding to a predetermined tree diameter they actuate a roller 146 thus opening a valve 142 and releasing fluid energy from the accumulator 152. This causes the blades 86, 88 to be pivoted towards each other to top the tree.
