Title: Cement slurry batcher apparatus and process
Inventor: BROWN RONALD O
IPC: B28C5/00
Filed: 1988-08-09
Granted: 1992-05-12
Abstract: CEMENT SLURRY BATCHER APPARATUS AND PROCESS        ABSTRACT          A novel process and apparatus for discharging, on a batch basis, cement and water as a slurry or in the form of separate discharges of slurry and cement,  where the materials so discharged contain a predetermined amount of water and a predetermined amount of cement, is disclosed.  A major quantity of water and all or a major quantity of the cement is mixed in a slurry mixer to produce a primary slurry.   A major portion of the primary slurry is then discharged, and the remaining slurry mixed with the remaining quantity of water for discharge as a second slurry.  A minor portion of the cement can optionally be added to a dry chamber for discharge therefrom.   The slurry mixer and dry chamber, which are substantially closed systems,  can be vented together, and then vented to atmosphere, so that air in the slurry mixer which is displaced during water and cement charging flows through the dry chamber.   While the normal discharge is from the slurry mixer in slurry form, in situations where the discharge is to be mixed with wet aggregate having a known water content, a minor portion of the predetermined amount of cement required for a concrete mix can be charged in the dry chamber so that it can be separately discharged with the discharge of the slurry from the mixer.  The predetermined amount of water and cement for a given batch can be determined by weighing the amount of water and cement separately introduced into the slurry mixer, and in cases where the dry chamber is charged with cement, the weight of cement added to it.

Title: Multiple fluorescence labelling with europium chelators
Inventor: DIAMANDIS ELEFTHERIOS P
IPC: G01N33/60
Filed: 1988-08-11
Granted: 1992-09-29
Abstract: ABSTRACT A conjugate for use in a labelling system comprises avidin or streptavidin linked to a carrier particle, having more than fifteen amino groups on its surface, which are individually capable of being labelled with an operable label.  The carrier particle is capable of being linked to the avidin or streptavidin to form the conjugate.  The conjugate is particularly useful in forming a fluorescent reagent system.  The carrier particle is labelled with a plurality of ligand moieties forming with a lanthanide metal ion, fluorescent chelates attached to the plurality of amino groups to provide at least fifteen labels.  The fluorescent reagent system, when excited to fluoresce, emits fluorescent radiation with an intensity amplified compared to intensity of fluorescent radiation emitted by the plurality of fluorescent lanthanide metal ion chelate moieties in a solution whereby the fluorescent reagent is void of any quenching effects due to multiple labelling in the fluorescent reagent system.  The fluorescent labelling system is particularly useful in binding assays.

Abstract: ABSTRACT OF THE DISCLOSURE            INTRAGASTRIC BALLOON WITH IMPROVED VALVE LOCATING MEANS     An intragastric balloon has an ellipsoid or like configuration so that the balloon implanted in the stomach tends to rotate or rock only about one axis when a surgeon attempts to manipulate the balloon, for example, for the purpose of finding a filler valve and inserting a filler tube into it.  For easy location, the filler valve is disposed on the equator.  A retrieval tab is mounted to the exterior of the balloon, to permit capturing of the balloon and retrieval from the stomach, after the balloon has been deflated and is no longer desired for weight control purposes.  Visual and X-ray opaque markers are located in the proximity of the valve and of the retrieval tab to facilitate their visualization with an endoscopic light when the balloon is in the stomach.

Abstract: ABSTRACT OF THE DISCLOSURE      Shift mechanism is provided for a gearbox, such as a transmission or transaxle, of a small vehicle.  The shift mechanism has three functions.  It shifts or changes the gear-engaged condition of the gearbox.  It moves a clutch between engaged and disengaged positions.  It also actuates a brake of the vehicle to move it between a braking position and a release position.  Further, the shift mechanism achieves all three of these functions through a single shift lever which is manipulated by an operator. The shift mechanism also causes the brake to be moved to its braking position at any time the gearbox is moved between a forward speed condition and a reverse speed condition, to avoid extreme, lurching movements of the vehicle.

Abstract: Determination of the effectiveness of endothelial cell seeding upon a vascular graft surface within the operating room environment would be desirable to maintain quality control in any clinical trial. In this study, five fluorescent stains, mithramycin, Hoechst 33342, sulfofluorescein diacetate, Nile red, and rhodamine 123 were evaluated for their ability to fluorescently label endothelial cells on graft material and subsequently allow determination of seeded cell number and cell spreading. Of these agents, rhodamine 123 produced the most desirable characteristics. It allowed excellent cell visualization after a 30 minute incubation. Unlike the other four stains, using rhodamine 123 caused the cellular cytoplasm to fluoresce bright orange at a 510 nm excitation wavelength while the underlying dacron or expanded polytetrafluoroethylene demonstrated minimal autofluorescence. No inhibitory effect on cell attachment to plastic or subsequent cell growth in culture was observed. This technique can be utilized in the operating room to visualize part or all of an endothelial cell-seeded graft and to permit a quantitative as well as qualitative evaluation of the seeding process.
