摘要:
A method for operating a tissue processor is described. During the operation of a tissue processor a reagent is fed from a container into a retort of the tissue processor, which retort does not contain any tissue samples. Thereafter, the reagent is returned into the container. During feeding, returning and/or in between feeding and returning a measured value is detected by a sensor of the tissue processor. This value is representative of a concentration of the reagent. During this feeding, this returning and/or in between no tissue sample is placed in the retort.
摘要:
The present invention relates to mixtures of substances based on organopolysiloxane polyethers and at least one further substance or component, preferably a polymer obtained from aqueous suspension, particularly preferably crosslinked functionalized polystyrene polymer beads, and also to the use of such mixtures of substances based on organopolysiloxane polyether together with crosslinked functionalized polystyrene polymer beads as free-flowing ion exchangers or free-flowing adsorbers, particularly preferably free-flowing monodisperse or heterodisperse anion exchangers or cation exchangers, but also free-flowing mixtures of anion and cation exchangers.

摘要:
An industrial truck has a vehicle frame (1) with a frame portion (2) having a lateral frame opening (2b) for receiving a battery block. A door (3) covers the frame opening (2b) and may be pivoted outwardly about a substantially vertical axis of rotation (A1). To allow the door (3) to be opened approximately 180°, the door (3) is connected to the vehicle frame (1) by a double hinge (5). A second axis of rotation (A2) is set apart and parallel to the first axis of rotation (A1) and is alterable in its position when the door (3) pivots about the first axis of rotation (A1). A device for obstructing a rotational motion of the door (3) about the second axis of rotation (A2) can be provided, which device can be active in the pivoting range between the closed position and an open position that is approximately at right angles.

Metal complexes of metals of the scandium group with an azo compound which conforms to the formula (I) or to one of its tautomeric structures where R is OH, NH2, NH—CN, arylamino or acylamino, R′ is NH2, NH—CN, arylamino or acylamino and R1 and R1′ are independently —OH or —NH2.
摘要:
The invention relates to a new process for the preparation of electrically conductive polyheteroaromatics by electrochemical oxidation of oxidatively polymerizable monomeric heteroaromatic compounds; according to the invention, an electrolyte system which consists of monomeric compound, water, polyhydric alcohol and sulphonic acid and/or sulphuric acid half-ester and in which the electrical conductivity displays a minimum is used.
摘要:
A method and an apparatus are described for infiltrating tissue samples with carrier material, preferably paraffin. A supply of carrier material is kept ready for use in a supply station. From there, the carrier material can be delivered into at least a first and a second container. In these first and second containers carrier materials of differing degrees of purity are kept ready for use, respectively, for performing various infiltration steps on tissue samples. By means of the described method and apparatus the tissue processor can be operated with as little interruptions as possible and an ease in operation is achieved.
摘要:
A hydraulic steering device (1) of a mobile machine, in particular of an industrial truck, includes a steering angle transmitter (2) in mechanically functional communication with a steering valve (4). As a function of the actuation of the steering angle transmitter (2), the steering valve (4) controls the connection of a steering drive (13) with a pressure fluid source (6) and a reservoir (11). To vary the translation ratio of the steering device in a simple manner, a bypass device (20) is operationally associated with the steering drive (13). By activation of the bypass device, the quantity of pressure fluid delivered from the pressure fluid source (6) to the steering drive (13) can be diverted to a reservoir (11).
