Title: High ortho etherified resole resin coating compositions
IPC: C08G8/36
Filed: 1979-06-28
Abstract: A coating composition comprises (A) a high ortho etherified phenol-formaldehyde resole resin, and (B) 1 to 95% wt. of a coreactive resin, said resin (A) being characterized by having (1) partially etherified methylol groups, 90 to 100% of which are ortho oriented; (2) condensed phenol-formaldehyde linkages comprising 25-90% essentially ortho oriented benzyl ether linkages and 10-75% methylene linkages of which 70-90% are ortho oriented and 10-30% are para oriented; and (3) an average degree of polymerization of less than 4, said resin (A) being prepared by reacting phenol and/or a m-substituted phenol with formaldehyde in an aqueous medium under reflux in the presence of a divalent electropositive metal ion while maintaining the pH at 4 to 7 using an organic acid, etherifying the resulting resole with a monohydric alcohol, then dehydrating.
Patent GB-2025546-A (GB)
Title: Transmissions for motor vehicle
IPC: F16H61/02
Filed: 1979-07-09
Abstract: A transmission for a motor vehicle comprises a gearbox and printed circuit cards 1-7 for controlling the gearbox. The output card 6 produces electrical output signals which actuate electropneumatic or electrohydraulic elements which cause respective gear ratios to be selected. A two-gear protection card 7 senses the electrical output signals and, if signals for more than one gear are present, actuates a disabling means to disable all the output signals for a predetermined period. After that predetermined period, if the signals for one of the gears was spurious, the genuine signal reappears and the gear is engaged. If signals for two or more gears re-appear, the disabling means operates for a further disable period. Since the output gear-selecting signals are sensed, as opposed to input signals from, for example, a gear selector, faults in the circuitry for producing the output signals as well as faults in the input circuitry will be detected. <IMAGE>

Title: Partitioned cartons
IPC: B65D5/489
Filed: 1979-11-26
Abstract: A carton e.g. for light bulbs has a bottom wall 10 from a central region of which are cut out two flaps 22. These flaps hinge about lines 24 and have nose portions 28 which engage behind each other so that the flaps stand up to form a partition between two light bulbs 42. The hinge lines 24 are parallel but not in line with each other so that the flaps do not lie snugly against each other but can be pressed resiliently together. This cushions the light bulbs and prevents them coming into direct contact with each other, and also holds them firmly in the carton. <IMAGE>

Title: Devices for supporting a structure such as a ladder against a surface such as a wall
IPC: E06C7/48
Filed: 1980-04-24
Abstract: A main plate 12 is pivoted to a mounting plate 10 by a bolt 14. A spring biassed dowel 26 on plate 10 engages in one of two holes 30, 32 in plate 12 to lock the plates in an operative position (Fig. 3) or an inoperative position.

Title: Shoe stiffeners
Inventor: LESTER R
IPC: D06N3/12
Filed: 1981-07-31
Abstract: Shoe stiffeners are known comprising a textile fabric impregnated with a stiffening composition. In the past certain of these have been made by impregnating textile fabric with a solution of stiffening composition. Others have been made by impregnating textiles with an aqueous emulsion of stiffening composition but these have not been as stiff or creep- resistant in wear as corresponding weights of solution impregnated materials. In the invention a plasticiser (solid at wear temperatures and melting at temperatures commonly used in activating shoe stiffeners e.g. above about 50 DEG C) and an aminoplast resin 3 to 30% based on dry weight of composition are included in the stiffening composition. The stiffeners are sufficiently stiff and creep- resistant to be satisfactory as replacements for many solution- impregnated stiffeners and may be stuck to the upper with hot melt adhesives or latex (if primed).
