Title: Improvements in or relating to liquid thermosetting phenolic resin adhesives
Inventor: BUTTREY DOUGLAS NORTON
IPC: C09J161/06
Filed: 1954-05-31
Abstract: A thermosetting adhesive comprises an aqueous solution of a resol and 0.5-10 per cent of weight of the solution of a novalac. The adhesive may be used for bonding paper, fabric or wood.  The novalac preferably has a melting point of 85-100 DEG  C. and is in the form of particles passing through a 100 B.S.S. mesh sieve.  In examples (1)-(3) Novolacs were prepared by refluxing 1 mol. of phenol and 0.87-0.90 mols. of formalin for 3 hours in presence of oxalic acid and thereafter dehydrated under vacuum.  A water-soluble resol was prepared by refluxing 1 mol. of phenol with 2.2 mols. of formalin for 45 minutes in presence of caustic soda; the resulting solution was stabilized by adding aqueous caustic soda solution and methanol.  To 100 parts of the stabilized resol solution was added 3 parts of novalac (if desired in admixture with hexamine), 5 parts of coconut shell flour and 12 parts of china clay.  Chalk may also be used as a filler.

IPC: B26D7/22
Filed: 1934-06-11
Abstract: 422,398. Machinery guards. JOHNEWERKE GRAFISCHE MASCHINEN-AKT.- GES., Bautzen, and STEGMANN, K., 37, Schafferstrasse, Bautzen, Germany. June 11, 1934, No. 17284. [Class 80 (iv)] A safety device, for paper-cutting machines or the like, has two guard members which are swung outwards in front of the knife during the descent thereof and which are supported while the machine is at rest in a raised inoperative position so as to leave a clearance below for the insertion of the pile of paper or the like. In the outward swing of the guard members, following the starting of the machine, one of the guard members becomes operative to remove obstructions, and is succeeded by the other, which becomes operative to prevent insertion in the machine of the operator's hands when the first mentioned guard reaches an outward position, in which it is no longer fully operative. The guards shown comprise rods 15, 19, extending across the front of the machine. Rod 15 is connected by links 14 to a spindle 12 and the rod 19 is carried by a bell-crank lever 16<a>, 16b, to a link 17. The latter is pivoted at 18 to the machine frame. In the position of rest, the rods 15, 19 are in the full-line position. When the machine is operated, a cam 2 on a rotating shaft tilts a beam 7<a>, 7<b> to turn the spindle 12 in the direction of the arrow b and swing the guard members outwardly. During the preliminary movement the rod 15 prevents the operator from moving his hands towards the cutting knife. The bell-crank lever 16<a>, 16b, moves in the direction of the arrow c, so that towards the end of the swing the guard rod 19 is in its operative position.

Abstract: 815,119. Honeycomb paper &c. BLACKBURN & GENERAL AIRCRAFT Ltd., and CLARK, F. M. May 24, 1957 [June 8, 1956], No. 17834/56. Class 96. A honeycomb or like hexagonal cell material is formed of paper or paper-base sheet material, e.g. resin-impregnated paper, by so arranging the constituent sheets and sticking them together by parallel lines of adhesive that when expanded there are complete cell edges along both sides. As shown, this may be done by turning in both edges of each sheet to an extent substantially equal to the width of the glue line. The first sheet 1 is laid with its inturned edges uppermost and is then glued in the usual parallel lines of which the outermost fall on the inturned edges 2, 3. The next sheet 4 is placed with its inturned edges downwards so that they are stuck to the inturned edges of the first sheet. The second sheet 4 is then given glue lines staggered between those of the first, and the third sheet 5 positioned in the same way as sheet 1, and so on until the required number of sheets has been built up. After adhesion of the sheets the stack is expanded and, if necessary the resin-impregnated paper is cured. In a modification, alternate sheets only have the inturned edges, the remaining sheets being narrower by the width of these inturned edges. Panels according to the invention may be joined together by nesting their complete cell edges and sticking them together.
