Abstract: A locking member for an open roof construction for a vehicle.This open roof construction is provided with a panel, which in the closed position closes an opening in the roof of the vehicle and which is movable from this closed position or to this closed position by means of at least one push-pull cable. This push-pull cable is displaceable by means of a driving wheel, which is rotatable in two opposite directions, while a locking member at least substantially prevents a rotation of the driving wheel by the push-pull cable. This locking member comprises two cooperating locking parts, the first one of these locking parts being stationary and the second locking part, when at rest, being maintained in the locked position, while this second locking part can first be brought from its locked position into its released position with respect to the stationary locking part by means of an actuating member and can thereafter be rotated in the two opposite directions, which rotation is followed by the driving wheel.

Abstract: Structures to serve as selective magnetic sorbents are formed by dissolving a cellulose derivative such as cellulose triacetate in a solvent containing magnetic particles. The resulting solution is sprayed as a fine mist into a chamber containing a liquid coagulant such as n-hexane in which the cellulose derivative is insoluble but in which the coagulant is soluble or miscible. On contact with the coagulant, the mist forms free-flowing porous magnetic microspheric structures. These structures act as containers for the ion-selective or organic-selective sorption agent of choice. Some sorbtion agents can be incorporated during the manufacture of the structure.

Abstract: An apparatus and a method destined for the production of metal powder, wherein inert gas, especially argon is admixed to a metal melt rising in a riser, thereby forming a metal froth which is pressurized likewise by inert gas, especially argon of high pressure in a pulverization chamber, at the same time, forming metal droplets. These are displaced from the pulverization chamber by the gas blown into the same, to enter an expansion chamber in the form of a collecting vessel, the metal droplets being accelerated in the passage from the pulverization chamber to the collecting vessel, at the same time, forming the finest metal powder.

Abstract: The disclosed invention relates to a counterflow type heat exchanger composed of plural heat exchange units characterized by unique inlet and outlet headers. Each header has an end face providing an opening to the header interior and a closed end face, both of which extend obliquely from the tube sheet to join at an apex and which are symmetrically arranged with respect to each other. Such a construction enables the flow of fluid passing through each heat exchange unit to be uniform across the width of the heat exchange unit.

Abstract: This invention provides an apparatus and a method for sanitizing beverage dispensing systems of the type using a pump that draws the beverage from a single port collapsible container which is otherwise air tight. The system consists of a manifold having a main manifold chamber with one input and at least one output, and a secondary manifold chamber having an input and an output. The drink dispensing hoses are attached to the outputs of the main manifold chamber, and either a sanitizing fluid or water is attached to the input of the main manifold chamber. The water may be provided through the secondary manifold chamber. Before connecting to the sanitizing fluid, the main manifold chamber is opened to the atmosphere, and remaining beverage in the dispensing hoses is drawn out by the pumps to the dispensing heads. Afterward, sanitizing fluid and water are drawn through the manifold and the dispensing hoses and heads, sanitizing the system.

Abstract: Elastomers are plasticized with a polymerizable monomer, in homogeneous admixture therewith, by adding the monomer to a latex of the elastomer, free of polymerization initiator, followed by coagulation of the monomer and polymer solids. The coagulated solids recovered from the latex may be compounded with a polymerization initiator for the monomer and a vulcanizing agent for the polymer and, optionally, an inorganic filler, and shaped into the desired product form. Polymerization of the polymer and vulcanization of the elastomeric polymer are initiated after shaping.
