Abstract: ABSTRACT OF THE DISCLOSURE A warning circuit particularly suited for indicating that an intermittently operated device has been operated for a predetermined cumulative length of time.  The circuit utilizes a coulometer as a current integrator that accumulates the intermittent periods of time during which the device operates.  At the end of the predetermined cumulative length of time, the impedance of the coulometer changes from a low level to a relative higher level.  This change in impedance renders a first transistor conductive and results in a warning indication.  A second transistor is latched into a state of conductivity that causes a feedback current to flow through the coulometer to maintain it in its high impedance condition.  The warning indication is controlled by an amplifier circuit which, in turn, is controlled by the second transistor.  Once the high impedance of the coulometer is achieved, the second transistor at all times retains its state of conductivity indicative of this condition, but the amplifier circuit is operative only when the intermittently operated device is in operation.

Abstract: (Abstract of the Disclosure) A fluid filter including a filter body having in-let and outlet passages communicating with an open ended chamber on opposite sides of a tapered seat area.  A cup-shaped fluid filter or strainer element is located in the chamber through the open end thereof and is adapted to be closely received in the seat area.  A bonnet assembly covers the open end of the chamber, is threadedly mounted to the body and is comprised of a bonnet, a bonnet nut and biasing means.  The biasing means is employed to exert a biasing force against the filter or strainer element to continuously urge it toward the seat area. At least the bonnet and bonnet nut are themselves interconnected in a manner that permits both rotational and limited axial movement therebetween. The disclosed structure facilitates access to the chamber and filter or strainer element without the necessity for removing the entire fluid filter structure from a service installation.  The interconnection between at least the bonnet and bonnet nut permits the bonnet assembly to be removed from the filter body as a single unit and the tapered seat area is configured such that the filter or strainer element is thereby retained in the chamber when the bonnet assembly is removed from the body for subsequent separate removal therefrom by hand.

Abstract: ABSTRACT OF THE DISCLOSURE      A multichamber cuvette for maintaining in independent and separate condition at least two reactants one of which may be a sample, until such time that it is desired to mix them for reaction with each other for photometric analysis in the cuvette.          At least one of the chambers has a pair of optical quality windows which windows are aligned with one another for analysis of the then liquid contents extending between the windows.  The uvette body is of upright construction, defining at least two such chambers laterally of one another, open at the top for filling separately or simultaneously, and interconnected adjacent their lower extremities by a passageway of inverted U shape.  The passageway is of an effective height exceeding the highest filling level of each chamber by a distance at least as great as any capillary rise in the passageway beyond such level of the particular liquid in that chamber.  Accidental mixing of the-chamber contents is prevented by entrapment of air in the passage-way by the respective liquids in the chambers and partially filling the legs of the passageway.  The resistance of the entrapped air to such mixing through the passageway mar be over-come at the time mixing is desired by the forced flow of fluids therethrough from one chamber to the other while one of the chambers is vented to the atmosphere at the top.  The passageway is so configured and also dimensioned in cross section as to allow for the free flow of liquid between the chambers once the entrapped air within the passageway has been removed.

Abstract: ABSTRACT OF THE DISCLOSURE    In a method of moulding articles in synthetic plastics, plasticised plastics material is fed by a screw within a cylinder, along the cylinder to a nozzle from whence the material is injected into the mould cavity.  The feeding of the material into the mould cavity is however effected by rotation of the screw almost in its forwardmost position instead of by longitudinal movement of the screw from its rearwardmost to its forwardmost position.  The longitudinal position of the screw is adjusted during filling of the mould cavity by biasing means acting axially on the screw and controlled by means sensing the position of the screw.    The temperature distribution throughout the cylinder, the nozzle, the screw and the screw tip is controlled by separate cooling circuits for the various zones, the various cooling circuits coming into operation at various times during a moulding cycle, as determined by timing means.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved selective adsorption process is provided for the separation of gaseous mixtures.  The process includes a number of steps.  The first step includes passing a feed gas mixture containing components A and B successively at a first pressure through two adsorption beds selective for com-ponent A until the evolving adsorption front of component A substantially reaches the outflow end of the first adsorption bed or has only insubstantially penetrated into the second adsorption bed; discharging an A-free product gas from the outflow end of the second adsorption bed; then interrupting the feeding of the feed gas mixture to the first adsorption bed.  The second step includes expanding both adsorption beds in the adsorption direction to a lower pressure sufficient so that proportions of unadsorbed component A emerge from the first adsorption bed, and so that such emerged proportions from the first adsorption bed are adsorbed in the second ad-sorption bed; and withdrawing an A-free gas from the second adsorption bed.  The next step involves at the same pressure as in the second step, conducting a further gaseous mixture in the adsorption direction through both adsorption beds, the partial pressure of component A in the further gaseous mixture being higher than in the feed gas; interrupting the feeding of the of the further gaseous mixture before the breakthrough of component A through the second adsorption bed; and withdrawing an A-free gas from the second adsorption bed.  The next step involves disconnecting both adsorption beds from one another, and expanding the first adsorption bed loaded substantially completely with component A to recover component A; and substantially simultaneously expanding the Abstract ... (cont'd) second adsorption bed, partially loaded with component A, in a countercurrent direction to the adsorption process and passing a purge gas in that countercurrent direction through the expanded second adsorption bed to desorb compon-ent A.  The final step includes reconnecting both adsorption beds with each other and charging the same to the first pres-sure of the first step.  This improved process provides for the separation of gaseous mixtures into at least two com-ponents in a purity and in a yield not attained by means of the prior art processes.
