Abstract: A stirring arrangement including an accessory for selective stirring of the base colors contained in hanging paint pots in paint stirring machines. The stirring machines have racks for suspending the pots and devices for stirring the colors therein, with the stirring arrangement including a further rack receiving at least one stirring lid with an associated paint pot, suspended between cantilever slides on the rack, the lid and a stirrer which is attached thereto being rotated by a chain extending along the length of the further rack and actuating a drive pinion thereon. A drive unit for driving the chain connected to a drive shaft of the stirring machine disengages the machine in the operating condition of the stirring lid on the further rack without the racks on the stirring machine being activated, and in the inoperative condition of the further rack intermittently activating the racks of the stirring machine.

Abstract: A lid with an adjustable "guillotine"-type pouring arrangement, which is especially adapted for mounting on the primary color or paint containers intended for car bodywork and which are employed in stirring machines. In this lid, a flat spring which is fastened with a rearward portion to the lid, in front of a stirring shaft of the stirring machine includes at its front side, a flange pressing against a sliding element and, at a distance from the fastening location, two vertically flanges arranged on either side of and proximate each of the longitudinal edges of the sliding element. Two helical coil springs are each connected, at the one end, to each of the flanges on the flat spring and, at the other end, to the rearward portion of the sliding element.

Abstract: The invention relates to a controllable flow pourer mechanism.This pourer mechanism comprises a valve mounted on an actuating device, of such construction that in closed position, the valve is kept in fluid-tight contact upon the lip of the pourer spout and that, from this position, in a first phase, the valve slides upon the lip of the pourer spout and, in a second phase, the valve carries out a rocking movement.The invention is applied especially to effect mixtures of liquid products.

Abstract: This invention relates to a weight measuring balance especially adapted for the proportioning of a liquid product mixture from cumulative formulas expressed in weight.The balance comprises a pan borne by a centrally fixed stress gauge captor, mounted upon a fixed frame and which furnishes a signal representative of the load's weight, whatever may be the position of the load on the pan, to a measuring device carrying out the display of the weight thus detected on a first display device.The invention is especially applied to the formulations of paints used in automobile body shops from cumulative formulas expressed in weight.

Abstract: Apparatus is provided for the preparation of mixtures in variable quantities from a single formulation giving the mixture in parts thereof. The apparatus includes a gauge, the vertical displacement of which, along a variable course, is obtained by a transformation, either amplification or reduction, of the displacement of an object along a predetermined path. Additionally the path can be divided into equal parts, such that at each instant the object and the gauge are positioned dividing respectively the path and the course in the same ratio. In one embodiment the object consists of a carriage which is translationally displaced along an approximately horizontal track, and the transformation is obtained by means of a ramp upon which is positioned a running wheel. The invention is particularly useful for providing mixtures of paint.
