Abstract: 1,225,597. Melamine. STAMICARBON N.V. 13 Nov., 1969 [16 Nov., 1968], No. 55700/69. Heading C2C. In a process for the production of melamine crystals by the conversion of urea to melamine in which the product gases are directly cooled in a pressurized cooling zone to provide under pressure a lean suspension of melamine crystals in a solution saturated with ammonia and carbon dioxide, the solution after separation of the melamine crystals being recycled to the cooling zone, the lean suspension of melamine is concentrated in at least one hydrocyclone to a concentration of 30-60% by weight of melamine crystals and the separated substantially melamine-free ammonia- and carbon dioxidesaturated solution is recirculated to the cooling zone, the pressure of the concentrated suspension of melamine crystals is reduced to atmospheric and the suspension, if necessary after diluting with a liquid medium to render it easily transportable, is transferred to a stripping column in which the ammonia and carbon dioxide present are stripped off and the melamine crystals are separated from the suspension.

Abstract: 1,225,765. Handle assemblies WILMOTBREEDEN Ltd. 18 April, 1968 [22 April, 1967], No. 18628/67. Heading E2A. A door handle assembly includes a mounting section 1 and a handle 7 pivotally supported by the mounting section and rotatably coupled through an overload clutch to a release element 23 arranged for connection to a release linkage of a door latch mechanism. In the construction shown the handle is mounted in the mounting section_on a shaft 18  which forms the output shaft of the clutch. The clutch is of the spring loaded dog type the handle being integral with the clutch input member and the release element integral with the output member; the input member is in the form of a toothed like projection 28 and the output member has a groove 26 with which the projection engages. The clutch spring 29 surrounds the shaft 17 as is compressed between the end portion 14 of the handle and a washer 30 which is axially located by a cross pin 32. If the door is locked so that movement of the release linkage and pins of the release element is blocked, any attempt to release the door by means of the handle 7 will merely overload the clutch so that normal handle movement will still occur. The handle is provided with the torsion return spring 33.

A process for manufacturing a decorative laminate comprises applying to a substrate a fibrous sheet impregnated with synthetic resin and including pigmented enamel and applying heat and/or pressure so that the sheet adheres to the substrate and presents a decorative face. The sheet may include fibres of cellulose, e.g. paper, and/or plastics, glass, metal or asbestos fibres. The impregnating resin may be melamine formaldehyde, a phenoplast, silicone, polyester, polyamide, polyurethane or a derivative thereof, epoxy resin, polyvinyl, polyolefine, polyfluoroethene, or cellulose derivative or rubber. The pigmented enamel may be added to glass paste before forming this into fibres for the decorative sheet, or metal fibres may be coated with enamel before forming them into the decorative sheet, or ground enamel may be added to a paper pulp, e.g. of cellulose, rayon polyester or polyamide fibres, prior to forming the decorative sheet, or the decorative sheet may be printed on at least one face using an ink containing ground enamel. The laminate may include, in the impregnating resin, a material which absorbs ultra-violet radiation, e.g. 2- hydroxy 4-methoxy benzophenone, to reduce ageing. The surface of the laminate may be formed with rounded pits and projections to give an abrasion resistant, non-reflective surface. The substrate may be a layer of plywood, mineral sheet, asbestos board, metal, or foamed plastics or impregnated fibrous sheet. It may be used as a weatherproof facing for buildings. The decorative sheet may be covered by a colourless paper or rayon sheet. The resins impregnating the various layers may be different.

Abstract: 1,258,656. Aerials. INTERNATIONAL STANDARD ELECTRIC CORP. 27 June, 1969 [22 Jan., 1969], No. 32629/69. Heading H4A.  In an aerial system, a turnstile aerial is symmetrically surrounded by a circular loop aerial, all elements of the aerials are flat, and they are arranged substantially in a plane. As described, the turnstile aerial consists of two centre-fed crossed dipoles (d 1 , d 1 ) and (d 2 , d 2 ), Fig. 1, and the loop aerial consists of four centrefed pairs of arcuate sections (r 1 , r 2 ), (r 3 , r 4 ), (r 5 , r 6 ), and (r 7 , r 8 ). The aerials are formed by printed circuit techniques on an insulating base a, Fig. 3, made, for example, of 1À5 mm. epoxyglass fabric, and each half-dipole of the turnstile aerial comprises four conductive strips arranged in spaced apart pairs on each side of the base, through which interconnections p are provided. Bridges B under the base connect together the two parts of each half-dipole and provide terminating points for feeder cables. The sections of the loop aerial are U-shaped, and are formed on the upper side of the base, with the closed ends of each pair adjacent each other. A central coaxial cable feeds each pair of sections individually through radially extending baluns T r , Fig. 4, and inductors L. Said inductors are formed on the lower side of the base under the sections, and their outer ends are connected to the legs of said sections by adjustable sliding bridges S. Tuning capacitors (6), Fig. 8 (not shown), may be connected across the outer ends of each balun, at points x, y, where the inner ends of the inductors L are also connected. The baluns T r  are of strip construction, and each comprises two paralleled radially extending tapered conductive strips (1), (1), Figs. 6, 6(a) (not shown), formed on each side of the base (a), two low-loss dielectric spacers (b), (c), over the strips (1), (1), which carry outer conductive strips (2), (3), and two low-loss dielectric spacers (d), (e) over the strips (2), (3), which carry screening conductive strips (4), (5). At the inner end of a balun the inner conductor (C) of the central coaxial feeder cable is connected to the strips (1), (1) and its outer conductor (M) is connected to the strips (2), (3). At the outer end of the balun the strips (1), (1) are connected to the strip (2) and the relevant inductors are respectively connected to the strips (2), (3). A metal housing under the insulating base of the aerial provides shielding, and means for attachment of the feeder cables. The aerials may be coated with protective lacquer and they may be enclosed in a radome. The aerial system may be fitted with a cage of the kind described in Specification 1,258,282, for reducing undesirably polarized radiation. The aerial system is stated to be suitable for use in a VOR beacon, or in a direction-finder with a manually-operated goniometer, or in an automatic direction-finder with a visual indicator.

Abstract: 1290916 Radar ESSO RESEARCH & ENG CO 17 Nov 1970 [19 Nov 1969] 56556/69 Heading H4D An apparatus for measuring the relative distance and attitude between a first object carrying two primary radars M1, M2 and a second object carrying two transponders T1, T2 does so by measuring M1T1, M1T2, M2T1, M2T2. In a system for berthing a ship S at a jetty J, Fig. 1, the primary radars are mounted in known positions on the jetty and are controlled by a computer C. The radars M1, M2 transmit on a frequency f 3  and the transponders T1, T2 are tuned to receive f 3  and transmit on frequencies f 1 , f 2 , respectively. The computer controls the radars to measure the four ranges R1-R4 in turn and then transmits the information over a V.H.F. radio link to the ship where the measurements are displayed on the bridge. Each master radar has switches for selecting the mode of range measurement. In the free run modes either range may be measured continuously and in the computer controlled mode the two ranges are measured alternately. To measure R1 a local oscillator ( 1 ) is employed, which tunes the receiver to f 1 ; for measuring R2 a different local oscillator (2) is employed. The ranges are measured by methods disclosed in Applications 56555/69 or 52795/70. The computer is also fed with information relating to the tides, jetty, ship and waterway to compute the actual position of the ship relative to its wanted position and the velocity and acceleration of the bow and stern. In other systems the positions of the primary radars and transponders may be reversed and the signals may be time coded instead of having different frequencies.
