Patent GB-607104-A (GB)
Title: Improved phenol formaldehyde condensation resins
IPC: C08G8/28
Filed: 1946-01-25
Abstract: A synthetic resin is produced by reacting under alkaline conditions 1 mol. of phenol and/or m-cresol, 0.2-2.0 mols. of 3.5-xylenol and more than one mol. of formaldehyde for each mol. of phenol or cresol and each mol. of 3.5-xylenol.  In place of m-cresol a mixture of cresols containing at least 40 per cent m-cresol may be employed.  The products are useful as adhesives especially for plywood.  They may be cured by baking at 90-120 DEG  C. or at room temperatures by use of a weak acid.  Fillers or extenders may be incorporated with the resins. The pH of the reaction medium is preferably 8.5-9.5 and the initial temperatures should be kept at 25-75 DEG  C., or if precise control of the reaction is possible, it may be allowed to rise to 100 DEG  C. When the proportion of 3.5-xylenol employed is relatively high, it is desirable first to react the phenol with formaldehyde and thus add the 3.5-xylenol if desired with further formaldehyde.  In a typical example, phenol, 3.5-xylenol and formaldehyde solution were mixed in a vessel with stirrer and reflux condenser, caustic soda solution was added to adjust the pH of the mixture, and the whole heated until a sample showed a satisfactory viscosity.  The mixture was then cooled, the reflux condenser removed and water removed by vacuum distillation until a sample of the mixture had a desired viscosity.  The resin was mixed with wood flour and used to make plywood from beech veneers. Figures are given for the shear strength of the plywood, both dry and after immersion in boiling water.  If the distillation under vacuum is continued until the resin has a higher viscosity, the product after addition of wood-flour and an acid catalyst, e.g. p-toluene sulphonic acid may be used as a gap-filling adhesive.  In other examples, the phenol and formaldehyde are partially condensed before addition of the xylenol, or m-cresol takes the place of phenol. Specifications 520,828 and 558,745 are referred to.

Title: Convertible ladder
IPC: E06C1/18
Filed: 1956-01-26
Abstract: 834,228. Ladders. NICHOLAS, M. G. M. Jan. 25, 1957 [Jan. 26, 1956], No. 2574/56. Class 20(2) [Also in Group XXV] The two sections X, Y, of a convertible ladder pivoted together at c are held in alternative positions by means of three arms pivotally connected together at e, the arms A and B being pivoted at their other ends to the sections X, Y, respectively, at points spaced from the pivot c, and the third arm being connected at its other end to the pivot c and being made in two parts C<SP>1</SP>, C<SP>2</SP> joined by a pivot d controlled by a stop device which limits the relative movement of the two parts when they are in the aligned position. In the closed position of the ladder the arms A, B, are in alignment and the third arm is upwardly folded. To use the ladder as a step ladder (Fig. 2). the arms are made to lead the section Y as it opens by first pulling a thumb-piece g on the arm A away from the ladder which can then open until the parts C<SP>1</SP>, C<SP>2</SP> of the third arm are in alignment. A lug f bent over from the part C<SP>2</SP> abuts the part C<SP>1</SP> at slightly past the aligned position and the third arm then holds the ladder open, closing being possible only after the pivot d has been lifted. To use the ladder as an extension ladder (Fig. 3), with the section Y turned through 180 degrees, the arms are made to follow the section Y as it opens by initially pulling the thumb piece towards the section X, the ladder being held open as before by the alignment of the parts C<SP>1</SP>, C<SP>2</SP>, of the third arm. In the closed position of the ladder the pivot e is situated slightly below the pivot c so that the arms do not foul the pivot c when the ladder is being opened to the extension position.

Patent GB-393023-A (GB)
Title: Improvements in or relating to the manufacture of goods of or containing rubber or similar material
IPC: C08J9/28
Filed: 1932-01-29
Abstract: Articles of microporous rubber and the like which are free from surface markings and easily removable from the mould are made by a modification of the known process in which dispersions are gelled and vulcanized under such conditions that evaporation of the liquid contained in the pores is prevented, characterized in that the mould surfaces are treated before the introduction of the dispersions with certain non-oily metallic soaps of the higher fatty acids.  The soaps promote gelling of the latex in contact with the mould surface and cause even distribution of the gas which collects between the metal plate and the surface of the latex.  The soaps are those of zinc, cadmium, magnesium, aluminium and ferric iron, and the preferred example is zinc stearate.  The salts are applied by spraying in an aqueous, or preferably in a methylated spirit dispersion.  The latter has the advantage that a dispersion is easily obtained, has good wetting qualities, and easily evaporates, leaving a film of lubricant on the mould surface, which may be warmed to assist evaporation.  The invention is particularly applicable to the processes described in Specifications 346,810, 351,937, 366, 120,377, 751, and 393,022. Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], also are referred to.
