IPC: C04B35/01
Filed: 1938-10-28
Abstract: 520,889. Agglomerating mineral substances; artificial stone. DITERICHS, W. Oct. 28, 1938, No. 31233. Convention date, Oct. 30, 1937. [Classes 22 and 70] Granular crystalline mineral substances are agglomerated by a binder which yields on firing crystals which are identical, isomorphous or compatible with the crystals of the substance being agglomerated. The granular substances may be abrasives such as emery, corundum or other forms of alumina, silicon, horon or other carbides or nitrides, bauxite, magnesite, chromite, zirconia, iron or chromium oxides, or oxides of beryllium, molybdenum, tungsten titanium, vanadium or thorium, or natural or artificial silicates. The binder consists of silica gel or other mineral gel with water and metallic oxides or salts. In an example, a product consisting of granular rhombohedral alumina agglomerated by crystalline rhombohedral magnesium tourmaline is prepared by mixing a solution containing magnesium chloride, aluminium hydrate mixed with phosphoric acid, sodium silicate, silica gel and boric anhydride. The mixture is ground, moulded, dried slowly up to 260‹C., heated slowly to 1260‹C., and then to 1370‹C. at which it is kept for some time and then cooled slowly.

Title: Improvements in printed circuit and method of making the same
Inventor: GREENMAN NORMAN LAWRENCE
IPC: H05K3/38
Filed: 1961-08-31
Abstract: 964,349. Printed circuits. ROGERS CORPORATION. Aug. 31, 1961, No. 31365/61. Heading H1R. A method of producing a printed circuit assembly is characterized by the steps of die-citting an electrically conductive pattern, adhesively securing the pattern to a surface of a mouldable fibrous base sheet embodying a curable resin, and subjecting the assembly to a moulding operation at temperatures and pressures which cause the base sheet to assume a predetermined shape and the curable resin impregnate to flow to cause a moulded skin to be formed upon and to cover all the surfaces of the base sheet. As shown in Fig. 2, a pattern blanking and embedding die 10 is used to secure the conductors to the base. A mouldable fibrous base member 14 impregnated with a curable thermosetting resin is fed under the die unit 10, and an elongated strip of metal foil 20, having its underside provided with a coating of thermosetting adhesive, is fed at right angles to the base member between male and female blanking dies 22, 24 respectively, the cutting portions of the male die 22 extending within corresponding openings in a stripping plate 30. When the movable member 12 of the punch press is lowered an indexing punch 40 first pierces the base 14 and then the heated male blanking die 22 cuts and blanks the metal foil pattern through the female die, the metal foil being embedded in the surface of the base and adhered thereto. The base member 14 is then moved along to position 44 where required holes are pierced through the base and conductors. After cutting the base material to the desired shape the individual circuit assemblies 61 are placed in a flash mould 53, Fig. 3, which is provided with pins 60 corresponding to the holes in the base member and which are preferably of smaller diameter. The assembly is then subjected to heat and pressure to effect curing of the mouldable fibrous material and to result in the formation of a resin skin 72, Fig. 6, covering the exterior surface of the base and the walls of the holes so as to render the base waterproof. During the moulding process the adhesive on the metal foil is cured and effects secure bonding of the conductors 62 to the base. Electrical conductors may be provided on both sides of the base, Fig. 8 (not shown), and a sandwich type unit, Fig. 9 (not shown), having intermediate conductors as well as conductors on the outer surfaces may be produced by placing several different sheets in superimposed relation in the mould and subjecting the assembly to heat and pressure to form a unitary member.

Abstract: 796,231. Resilient mountings. METALASTIK, Ltd. Aug. 31, 1956 [Nov. 8, 1955], No. 31955/55. Class 108(3) The invention relates to vibration absorbing mountings of the kind comprising a ring-like mass (e.g. a complete ring or a plurality of angularly-spaced blocks) of rubber 11 disposed between a base member 5 and a supported member 9. According to the invention, the mass 11 has a plurality of circumferentially-spaced pockets 17 and the support and/or base member 5 has a plurality of projections 16 each to enter one of the pockets 17. The projections 16 serve to limit downward deflection of the member 9. Upward deflection is limited by a conical shaped head 14 which is rigid with the projections 16. As shown, the mass 11 is in the form of a continuous ring in which is embedded a frusto-conical portion 7 of the base member 5. The projections 16 are carried by a plate 24, to which is threaded at 23, a column 12 carrying the head 14. The position of the latter and of the projections 16 axially of the mounting, may be adjusted by the insertion of shims 27. The object to be supported by the mounting may be secured to a peripheral series of threaded holes 28 or to a central bore 29. In a modification (Figs 1 and 2, not shown) the head 14 and projections 16 are carried on a member which is mounted in screw threaded engagement with a member which is normally secured by further screws to the supported member 9. In order to adjust the position of the head 14 and projections 16, the screws are released and the member is rotated relatively to the supported member 9. The head 14, and the screws are re-engaged, when the desired degree of adjustment has been achieved. In a further construction (Fig. 3, not shown), the head 14 and projections 16 are carried by a member which rests on adjustment screws carried by the member 9. The position of the head 14 and projections 16 is thus adjusted by rotation of the screws.
