Inventor: HASLER D J
IPC: B41M5/165
Filed: 1976-11-25
Abstract: A method of encapsulating finely divided particulate material, such as minute droplets of a water-immiscible liquid, to produce microcapsules in which the particulate material is surrounded by polymeric shells, comprising the steps of forming a dispersion of the particulate material in an aqueous medium containing a water-soluble ureaformaldehyde precondensate, a water-soluble melamineformaldehyde precondensate and a water-soluble polymer which is capable of being cross-linked by said precondensates, and condensing said precondensates by acid catalysis with resultant cross-linking of the polymer about the particulate material so as to form the polymeric shells. The polymer may be a cellulose derivative, starch, a starch derivative, a polyacid, a polyester, a polyanhydride copolymer, a polyacrylamide or a polyacrylamide copolymer, and is preferably an acrylamide/acrylic acid copolymer.

Abstract: This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particular fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins. The titanate-phosphite adducts serve to reduce the viscosity of filled epoxy resins, thereby permitting higher filler loading, to enhance the tinctorial power of pigments, and to render casting resins water-extendible. The titanate-phosphite adducts are the reaction products of one mole of a compound having the formula (RO)4Ti and two moles of di-substituted hydrogen phosphite, (R'O)2P(O)H, where R and R' are monovalent alkyl, alkenyl, aryl, aralkyl or alkaryl. Both R and R' may be alkoxy, aroxy, bromo or chloro-substituted derivatives of the aforesaid groups. R may have from 1 to 18 carbon atoms, preferably 3 to 12, except where the titanates are used for water-extension, where R is preferably 6 to 12. R' may be from 3 to 18, preferably from 6 to 14.

Abstract: An axially elongated ball bushing is inserted into a bore in a housing. The ball bushing includes an axially elongated cage having a plurality of ball loops each extending in the axial direction of the cage and containing a number of balls located in a loaded ball duct and an unloaded ball duct of the loop. Each loaded ball duct is open through the radially inner and outer surfaces of the cage. The ducts of the loops are arranged so that, in each loop, its loaded ball duct is adjacent the loaded ball duct in one adjacent loop and its unloaded ball duct is adjacent the unloaded ball duct in the other adjacent loop. A joint race insert formed of a thin hardened sheet steel bridges each pair of adjacent loaded ball ducts and the race portions of the inserts are bent radially outwardly against the surface of the bore by the loaded balls, however, the inserts do not yield in the thickness direction.

Abstract: A combined X-ray fluoroscopy and radiography device includes an X-ray image-intensifier 4, video apparatus 24, 26, means for disposing a photographic film 27, dispensed from feed-spool chamber 28 to take-up chamber 29, in the optical path directly adjacent the intensifier output screen 14, and a ring 30 urging the film against the intensifier exit window during an exposure. The exit window comprises a fibre optic plate 6. To prevent damage, a replaceable fibre optic plate 15 is applied thereto. Exposure is sensed optically via the film, and exposure or video input intensity is adjusted by controlling intensifier gain, e.g. by varying the intensifier accelerating voltage in conjunction with a metal film covering the fluorescent screen 14, whose electron permeability varies by 1:10 for a 1:2 accelerating voltage change. Auxiliary optical means project identification symbols onto the film 27 and/or camera 24. The film image can be secured in a window in an indexed card of an addressable indexed-card information storage and retrieval system for addressable retrieval and automatic projection. <IMAGE>

Abstract: The invention is a method of localising a source of radiation using a radiation detector (4) in a known field (1). This method can be used for example with a plane's (5) radar warning device to locate radar stations. With this invention, one selects a number of determined locations (A, B) to the position in the space. With the radiation detector one observes how the locations (A, B) are radiated from the radiation source (4). For each location, the field is divided partly into areas of which all points are in the line of sight of the location, the clear sight area (8, 9), and partly into extraneous areas. Assuming that the chosen locations are illuminated, logical operations are used to combine their clear sight area and only those parts of the field which are covered by some part of each location's combined area for formation of the new areas are observed. These areas, which are more delimited than any of the clear sight areas of the locations are the possible places where the radiation source is situated.<IMAGE>
