Filed: 1986-02-26
Granted: 1989-12-28
Abstract: A precious stone setting, especially for diamonds, is achieved without adversely affecting the value of the stones, and in an essentially invisible way, by forming slight notches at the angles of the culet in such a way that the depth of the notches is small and the distance separating the bottom of two opposite notches is very much greater than the width of the table of the stone. A metal matrix is used to hold the stone, the metal penetrating into the notches.

Abstract: A process for quantification of cell populations or subpopulations, by incubating a sample with labelled antibodies directed against characteristic surface antigens of the cell population to be quantified to form labelled antibody/antigen complexes. Standards with known, differing particle concentration and having comparable sedimentation behavior to the cells to be determined and further, carrying molecules which are directed against the labelled antibody or a part hereof are also incubated with the labelled antibodies. The cells of the sample solution, as well as the particles of the standard solution, are separated off from the excess labelled antibodies and the amount of the labelling is measured not only on the cells but also on the particles. By comparison of the measurement value from the sample with the measurement values from the standard solutions, there is ascertained the number of cells to be determined in the sample. The standard and a reagent kit for carrying out the process are also the subject of this application.

Abstract: A mould-changing arrangement is applied to a gp. of injection moulding machines with their moulds clamped in the closure units, each injector unit being withdrawn from the mould and having a disconnecting extruder. The arrangement has mould-change tables at the rear of the machines and mould guides for two mould positions; the tables are moved parallel to the axes of injection so that their guides alternate in the clamping space and form a conveyor path at right angles to the axis of injection; a mould transporter moves a mould to the clamping space along that path from the changing table and vice versa; the system has a mould store to hold a number of moulds, a conveyor to move moulds between the changing tables, and the store. This last conveyor has a device to move the moulds, a guide and a position which can be turned through at least 180 deg. in a guide parallel to the axes of injection it alternates in the connecting position. The conveying device is adjustable in height; one mould guide forms a conveyor path with one mould guide of the changing table or with one of one storage position; the injection moulding machines on the two sides of the guide are arranged symmetrically to them.
