Title: Colour image formation by reversal process - with non diffusable coupler in silver halide layer
IPC: G03C7/30
Filed: 1973-11-07
Abstract: In a reversal process for forming a colour image in which an Ag halide colour photographic film is exposed and subjected to a black and white development followed by selective re-exposure of each colour forming layer and development with a chromogenic developer contg. a diffusible, colour coupler to give a non-diffusible dye image with a complementary colour relative to that to which the particular Ag halide layer is sensitive, the improvement comprises incorporating a non-diffusible colour coupler in one or more of the Ag halide layers, the colour being complementary to that to which the Ag halide layer is sensitive. The colour density in a partic. Ag halide layer is improved for a given concn. of Ag thus allowing the Ag concn. to be reduced and resulting in improved image sharpness. Chromogenic development time can also be reduced without altering image quality and grain size of image dyes is improved.

Title: Central drawgear for railway wagons - has load transmitting yokes with spring on ends of arms
IPC: B61F5/42
Filed: 1973-11-08
Abstract: The patent considers, for example, a rigid axle wagon coupled to one with bogies. The traction effort is transmitted from the coupler (A) to a point on the wagon (K), usually the underframe. There may be a spring controlled sub-structure, in yoke shape, to transmit force to the underframe. When on a curve, the centre line of the wagon and that of the coupler gear are not in the same line. The geometry of the yoke assembly is such as to apply different forces at either side, due to the control of the two springs. The springs assist in re-aligning wagons and drawgear once they regain straight track.

Title: Org. substances recovered from pulp mill waste water - using column of phenolic resin ion exchanger
IPC: C02F1/42
Filed: 1974-06-10
Abstract: Organic matter is recovered from waste water from pulp mills by means of a layer of a powder resin in a column The resin is eluted after being satd. by coloured substances, pref. using the method used in centralising the colour of waste water from pulp bleacheries. The resin is activated by an acid soln. whereafter waste water having a higher pH-value than liq. phase of the activated resin and pref. on the alkaline side, is passed through the layer of activated resin. This results in change of the volume of the resin due to pH-value change being counteracted by adding the acid soln. batch-wise while treating the waste water. The addn. should take place in that part of the cycle which is between the activation stage and the elution and in such a way that the pH-value of the resin layer is lowered several times during the treatment of the waste water.
