A device for facilitating the ventral screwing together of dens fractures with compression screws, characterized by a guide tube assembly comprised of two guide tube casings which are pivotably joined near one end by means of an articulated joint, and which are adjustable within a predetermined range of angles by an adjusting means. Bore wires, milling tools and compression screws can be introduced into the dens via the guide tube assembly at precise spatial and angular relationships set by the aiming tube assembly.

In carrier-free continuous deflection electrophoresis problems are encountered in the collection of fractions and it is necessary to use hose pumps with a number of channels corresponding to the number of fractions desired. This arrangement is not only elaborate and susceptible to disturbance, for a great variety of reasons, but even more importantly it necessitates a certain minimal flow velocity within the separation chamber. To improve the effectiveness of separation it is proposed by the present invention to adjust the outflow rate from the separation chamber in the region of its outlet end by introducing an additive medium with a predetermined flow rate in countercurrent to the flow direction of the separation and sample media. In this way the time the sample spends in the electric field and hence the corresponding separation effect is considerably increased.
摘要:
A method and apparatus for determining the fluidity of a liquid such as blood or serum having the steps of drawing the liquid from the source through a capillary tube measuring cell into a reservoir unit and returning the liquid back through the tube at a constant flow velocity while measurements are made. The pressure difference between the ends of the capillary tube are directly related to the viscosity of the liquid.
摘要:
The invention relates to a method and apparatus for carrier-free deflection electrophoresis, in which a separating media and a sample to be examined flow through a separating chamber between a pair of electrodes in a series of reversing bulk fluid flow along the direction of the electrodes, thereby separating the sample into zones which are to be collected into fractions for analysis or further processing. Among other things, the apparatus and method enable high-resolution separation of particles that can be performed in miniaturized chambers in electrophoresis modes including isoelectric focusing, zone electrophoresis, and isotachophoresis.

Method of designing a tooth replacement part, which is intended to be mountable on a residual tooth area and in which a spacing (1) is provided between the tooth replacement part (2) and the residual tooth area (3), and the subsequent step of examining whether one or more undercuts (4) exist in the tooth replacement part. Method of processing a designed tooth replacement part having one or a plurality of undercuts, wherein a spacing is provided between the tooth replacement part and a residual tooth area and wherein a shape of the spacing is modified so as to remove the undercut or undercuts from the tooth replacement part. Method of avoiding the formation of undercuts originating from the provision or the modification of a spacing. Tooth replacement part having a spacing, wherein the spacing of the tooth replacement part has first and second spacing areas and an intermediate transition area, said transition area being free from undercuts. Computer-readable medium with instructions for said methods.
