Abstract: ABSTRACT OF THE INVENTION      The present invention relates to a simple and accurate method to be applied in immunoassay technique for separating the free ligand from the antibody-bound ligand.    The method involves the use of a solvent extraction operation which freezes the equilibrium between the free- and bound-fraction.  The solvent to be utilized should be slightly water miscible or completely water immiscible, having the properties of marked selective extraction power towards the antigen.  The method is applicable in a liquid-liquid system, a solid-liquid system and solid-solid system.    The method is useful for radioimmunoassay, free radical assay or metallo-immunoassay, being most versatile having also the advantage that as a result of the free ligand being extracted into the solvent, the determination of the free and/or bound fraction compares very favourably with the known prior are methods in immunoassays.

Abstract: -- A B S T R A C T --A sedimentation basin for purifying waste water includes first and second basins separated by a baffle and a tube settler mounted substantially horizontally in the baffle.          The tube settler comprises a plurality of individual tubes which communicate liquid between the two basins.  A mechanism is provided to flow unclarified liquid into the first basin and slowly through the tube settler, whereby particles suspended in the unclarified liquid settle onto an inner surface of the tubes, and the resultant clarified liquid flows into the second basin.  A tube cleaner is mounted on the device for intermittent registry with an upstream end of the tubes, and creates a suction backwash therein during the registry which reverses the direction of fluid flow with sufficient velocity to dislodge and draw the settled particles from the inner surface of the tubes, and flush the same into a sludge disposal duct.

Abstract: ABSTRACT The invention relates to a change-under-load transmission having an input shaft (1) and an output shaft (6), each carrying a pair of gearwheels (2,3; 4,5). A composite layshaft comprises two pairs of coaxial shafts (7,8; 9, 10) which are aligned axially with one another. At their adjacent ends these shafts carry friction coupling elements (25,31 and 25, 30) which have effective coupling faces (25', 31'; 26' 30).  At their remote ends each of the coaxial shafts carries a gearwheel (23, 27; 24, 28) which is in permanent mesh with an associated one of the gear wheels on the re-spective input or output shaft. Between the adjacent ends of the two pairs of coaxial shafts a central friction coupling element (32) is positioned so as to be freely slidable axially with respect to the coaxial shafts. Corre-spondingly positioned ones (7, 9 in Figure 1; 8, 10 in Figure 2) of the two pairs of shafts are supported so as to be axially inwardly slidable inde-pendently of one another out of a rest position into which they are biased by springs (21, 22 in Figure 1; 45, 46 in Figure 2), and the other shaft (8, 10 in Figure 1; 7, 9 in Figure 2) are axially immovable. In the rest position of the shafts the effective coupling faces (30' 31' in Figure 1, 47' 48' in Figure 2) of the coupling elements on the slidable shafts are nearer the central coupling disc than the coupling faces (25' 26' in Figure 1 and 49', 50' in Figure 2) of the coupling elements on the axially immov-able shafts.

Abstract: Control System for Sequentially Actuating Fluid Actuators Abstract The heretofore known transmission control systems providing automatic sequential engagement of the fluid clutches have valves directly controlled by the operator and are not readily convertible to be pilot operated.  The present invention has a selector valve movable between first and second positions for communicating a supply line with first and second fluid clutches respectively.  A fluid actuated valve is moved to a first position communicating a third fluid clutch with a drain line when the fluid pressure in a fluid chamber threof drops below a preselected value and to a second position communicating the supply line with the third fluid clutch when the fluid pressure in the fluid chamber exceeds the preselected value.  A dump valve drops the fluid pressure in the chamber below the preselected value in response to a momentary pressure drop in the supply line upon moving the selector valve between the first and second positions.  An orifice delays filling of the fluid chamber until the selected one of the first and second clutches is engaged.  The elements of the control system are fluid actuated and are, in effect, pilot operated.
