Title: New compositions with a base of formophenolic resins and a method for their preparation
IPC: C08L61/10
Filed: 1969-12-30
Abstract: 1,259,724. Phenolic resin impregnated paper laminates. SOC. CHIMIQUE DES CHARBONNAGES. 30 Dec., 1969 [31 Dec., 1968], No. 63322/69. Heading B5N. [Also in Division C3] A composition suitable for preparing laminates comprises a phenol-formaldehyde resin and an ester of a monohydric alcohol and a carboxylic acid of formula R-Z(COOH) 3  where R is H or COOH and Z is a 5 or 6 membered ring. The phenol-formaldehyde resin may be prepared from a phenol, e.g. phenol itself, an ortho/meta/ para-cresol mixture or a meta/para-cresol mixture, and formaldehyde in the form of formalin or paraformaldehyde, in solution in isopropanol and benzene and in the presence of a basic catalyst, e.g. NH 3  or Na 2 CO 3 . Where Na 2 CO 3  is used it is afterwards neutralized-with H 2 SO 4  and the Na 2 SO 4  so formed filtered off. The carboxylic acid may be trimellitic, a cyclopentane tri- or tetracarboxylic or a cyclohexane tri- or tetracarboxylic acid. The ester groups, R 1 , R 2 , R 3  and possibly R 4  may be alkyl, cycloalkyl, aralkyl, aryl or heterocyclic groups. The ester may be added to the phenol and formaldehyde before or during reaction or to a liquid form of the resin. Alternatively the acid and alcohol or alcohols may be added and the ester prepared in situ. Butanol, benzyl alcohol and 2-ethyl-hexanol are added for this purpose. The composition may also include a filler, e.g. silica or sawdust and a diluent e.g. isopropanol or ethanol. Laminates are prepared by dipping sheets of Kraft paper in the composition, removing the solvent and heating and pressing them together.
Patent GB-647047-A (GB)
Abstract: 647,047. Overhead conductors for electric traction. WATSON, C. Oct. 11, 1948, No. 26474. [Class 104 (iii)] A conductor crossing for overhead trolley wires for electric traction vehicles has pivoted end brackets 1, Fig. 1, for the attachment of the ends of wires 16, which are clamped therein by screws 18, the brackets each having a lug 5 which is pivoted on a bolt 7 in the bifurcated end 6 of the crossing 3, and extends parallel with a coacting face 10 of the crossing, so that when a conductor wire 16 is tensioned and its end clamped in the bracket 1, the ensuing outward and upward swing of the bracket is countered by adjustment of a screw 11 which is screwed into the face 10 of the crossing in a position such that its head bears on a face 9 at the underside of the end of the lug 5. Vertical shoulders 4 on either side of the lug 5 are thus brought into close engagement with vertical abutment shoulders 8 on the bracket, thereby ensuring a continuous track for the current collector (not shown). Fig. 2 shows a modification comprising one end of a connector fitting wherein a bracket 1 for receiving and clamping one end of a wire 16 has a bifurcated vertical inner end which receives a lug 20 on the adjacent end of the connector and is pivoted thereto by a bolt 22. The pull of the wire tending to swing the bracket 1 clockwise about bolt 22 is countered by an adjustable screw 11 with its head in abutment with a vertical lug 23 on the bracket 1 and its other end screwed into a vertical face 24 on the connector.
