Abstract: ABSTRACT                  BIOLOGICAL ANALYSIS    A particle agglutination assay for antigens, antibodies and other binding proteins such as rheumatoid factor, uses two different, microscopic or submicroscopic particulate reagents.  The first particulate reagent binds with the antigen or antibody under assay, and then the second particulate reagent is added which binds only to those first reagent particles which have bound to the antigen or antibody under assay, so causing agglutination. The free unbound first or second particles are assayed to indicate the presence and/or amount of the antigen or antibody under assay.  The assay of rheumatoid factor may be so conducted to reveal the fractions of each immunoglobulin class of RF present.  The assay is part-icularly useful for small quantities of antibodies present in human sera indicating allergy, infection or autoimmune diseases.

Abstract: PULL-BACK RAM CYLINDER APPARATUS                ABSTRACT OF THE DISCLOSURE      A pull-back ram cylinder apparatus in combination with a vertical mold clamping machine to be incorporated in a vertical molding or casting machine.  The pull-back ap-paratus comprises a hydraulic cylinder for actuating a hollow ram.  A ram extension consisting of the ram and a ram rod extending into the ram in a thread engagement is slidably fitted in the cylinder.  The ram rod extends downwardly from the cylinder and is connected to a movable platen of the clamping machine carrying a movable mold.          The cylinder has a lower throttle portion in which radial openings for discharging an operation oil are formed in an axially spaced arrangement.  The inner diameter of the throttle portion is slightly larger than the outer diameter of the ram.  The throttle portion having the axially spaced openings serves, in cooperation with the head end portion of the ram, as bufferring means by which the movable mold is allowed to come into contact gently with a stationary mold.  The thread engagement of the ram and the ram rod is advantageous in that the positional relationship between the movable platen and the ram can be easily adjusted according to the change of the thickness in molds.

Abstract: ABSTRACT OF THE DISCLOSURE:            An arrangement for separating a starter bar from a cast strand in a continuous casting plant has an arcuate strand-guide part and an approximately horizontal strand-guide part including a cutting device for the cast strand. The starter bar has a start-er bar head that is connectable with the cast strand in a direct casting connection and may be re-used, i.e. a socalled "permanent head". It is disconnectable from the cast strand by a separating device arranged in the strand guide. The starter bar is convey-able out of the strand guide by a lifting device. In order to be able to separate the starter bar from the cast strand even if the permanent head cannot be disconnected from the cast strand, the separating device is provided in front of the strand-guide part that includes the cutting device. The lifting device is arranged also in front of the strand-guide part including the cutting device, at a short distance behind the separating device, i.e. at a distance that is shorter than the length of the start-er bar. As the connection between permanent head and starter bar, a hook-shaped coupling is provided, which is open towards the upper side of the starter bar.

Abstract: TWO-CYCLE ENGINE WITH FUEL INJECTION               ABSTRACT OF THE DISCLOSURE       The invention contemplates electronically controlled fuel-injection for a single or multiple-cylinder two-cycle internal-combustion engine wherein each cylinder has its own independent crankcase region in which to receive and compress inlet air and fuel, prior to delivery of combustible mixture to the head or combustion end of the cylinder. Fuel is injected directly into each crankcase region during only a portion of the stroke involving induced intake of air therein, i.e., during only a portion of the rise of each piston in its approach to top-center position, and while pressure within the crankcase region is relatively uniform. The time-duration of actual injection is relatively short, to enable identical injections in each cylinder, each such injection being identically timed with relation to position and displacement of its associated piston.

Abstract: ABSTRACT OF THE DISCLOSURE A collapsible mold core comprises an inner core member defining opposed first and second ends.  The inner core member tapers transversely to a reduced diameter from the first to the second end.  A plurality of outer core members are attached to the lateral exterior of the inner core member in longitudinally slidable relation to it be-tween first and second sliding positions.  The outer core members define first and second ends corresponding in posi-tion to the first and second ends of the inner core member, with the outer core members tapering inwardly in transverse dimension from their second to their first ends to provide are opposite taper to that of the inner core member.  The mold core is of lesser transverse diameter in the second sliding position then in the first sliding position.  This permits the molding of an object such as a straight-walled bucket having an inwardly-projecting lip about the mold core while it occupies the first sliding position.  There-after, removal of the object from the core can be accompanied with the transfer of the mold core to the second sliding posi-tion, permitting the removal of the bucket from the core.
