Abstract: An analyzer has a horizontally disposed baseplate on which primary containers and secondary containers are disposed, a pipetting needle, a transport device, and a control device. The pipetting needle is formed of an electrically conductive material and is connected to a metering device by a tubing, and is for transferring a predetermined volume of liquid each time from a primary container to a secondary container. The transport device is for the controlled transport of the pipetting needle in three directions at right angles to one another, two of the transport directions extending horizontally and the third transport direction extending vertically. The control device is for controlling the metering device and the transport device.

Abstract: Vitamin E acetate, C.sub.3 -linked triesters, glycerin, t-butanol, and transesterified oil/polyethylene glycol are effective dispersing agents for use with hydrofluoroalkanes. Effective amounts of the above are effective in suspending medicaments which are useful in inhalation aerosols, and especially meter-dose inhalers.

Abstract: A processing station for making a fluorescence polarization measurement on a sample in a cell under examination in a device for chemical and biochemical analysis, the analytical device containing a conveyor for conveying cells. In order to make fluorescence polarization measurements outside the conveyor, the processing station is separated from the conveyor and contains a measuring device means for making fluorescence polarization measurements on a sample in a cell, and an automatically controlled change-over and positioning device for removing individual cells from the conveyor, transferring a removed cell to a measuring position in the measuring device, and returning the cell to its original position on the conveyor after the measurement.

Abstract: An analytical device incorporating a system for suspending particles includes a conveying device for positioning a pipetting needle at a distance from the central longitudinal axis of the reaction vessel. Particles are suspended by delivering amounts of liquid reagent to two different positions at a predetermined distance from the central longitudinal axis of a reaction vessel, such delivery generates a flow in the reaction vessel which suspends particles exclusively by injection of liquid, thus avoiding the need for subsequent shaking.

Abstract: A conveyor is useful for conveying cuvettes to one or more processing stations. The conveyor has a plate-shaped rotor magazine with a number of resilient retaining elements for releasably holding cuvettes along the periphery of the magazine. This allows the cuvettes to be inserted and removed by a simple linear motion. Preferably, the retaining elements are constructed to cover the openings in the cuvettes while they are being held along the periphery of the magazine.

Abstract: Polymeric coatings having optically non-linear or optically anisotropic properties in selected areas and of any arbitrary shape including a pattern. These zones are sharply defined from surfaces having centro-symmetrical or isotropic configurations or from surfaces with different optically non-linear or anisotropic properties. The polymeric coating has optically non-linear and/or mesogenic side chains, selected surface areas of which are cross-linked by the action of light, the zones which have optically non-linear or anisotropic properties being subjected to the influence or orienting fields or forces during the cross-linking process. The distances between optically different zones are limited to typically about 1 .mu.m.

The compounds of formula 1 are potent inhibitors of phospholipases A.sub.2 (PLA.sub.2 's) and are therefore useful in the treatment of inflammatory diseases, such as psosiasis, inflammatory bowel disease, asthma, allergy, arthritis, dermatitis, gout, pulmonary disease, myocardial ischemia/reperfusion, and trauma induced inflammation, such as spinal cord injury.

Abstract: A pipetting device contains a pipetting needle connected to metering device for transferring a volume of liquid from a primary vessel to a secondary vessel. Primary vessel and secondary vessels are disposed on the same or different vessel carrier units, and each vessel has a clearly defined position relative to the vessel carrier unit. Additionally, a device is provided for controlling conveyance of the pipetting needle in three directions. The controlling device controls the metering device and the conveyance device. The pipetting device independently determines coordinates of the pipetting positions for each vessel carrier unit. For each vessel carrier unit at least one reference member, which is part of the vessel carrying unit or is directly and permanently connected thereto, may be provided. These vessel carrier units have flat surfaces which are accessible to sensing the pipetting needle.

Abstract: An apparatus for use in depositing and staining cytological material on a microscope slide has an elongated hollow tube, a base member, at least one flange, and a base plate. The base member is attached to the bottom end of the tube and projects outwardly from the tube perpendicular to the longitudinal axis of the tube. At least one flange is connected to the base member and outwardly-extends from the base member perpendicular to the longitudinal axis of the tube. The base member has a recessed area configured to receive the microscope slide, and slots configured and dimensioned to receive the flange. A passage in the base plate extends from each slot to releasably secure the respective flange when the tube is rotated. As designed, this apparatus advantageously allows individual staining of a slide, thereby preventing false-positive results due to floater cells which can translocate between slides in a common bath.
