Patent DE-3687232-D1 (DE)
IPC: C12Q1/34
Filed: 1986-12-19
Granted: 1993-01-14
Abstract: The presence or absence of a predetermined target microbe in a sample is determined by adding a testing medium to the sample, or vice versa. The testing medium provides a selective growth medium for the target microbe and includes a specific nutrient which only the target microbe can metabolize. This specific nutrient is modified by attaching a sample-altering moiety thereto, thereby converting the nutrient to a nutrient-indicator. The sample-altering moiety is activated to alter the sample only if the specific nutrient is metabolized by the target microbe. The sample-altering moiety can be a material which changes the color of the sample (visible or non-visible) or changes an electrical characteristic of the sample, or alters some other detectable characteristic of the sample. The testing media does not have to be kept sterile, and the testing procedure does not have to be performed in a sterile environment.

Abstract: A process for separation of the mineral components of a copper/molybdenum sulfide ore by flotation including (a) crushing and grinding the ore to liberate the minerals; (b) in a primary flotation circuit, adding a molybdenum collector selected from the group of hydrocarbon oils, and a frother; (c) floating a primary (molybdenum) concentrate in the primary circuit in the absence of a copper collector; (d) directing the primary molybdenum concentrate to an upgrading separation circuit to produce a final molybdenum concentrate; and (e) directing the non-float of the primary circuit to a secondary scavenger circuit for recovery of copper and additional molybdenum with addition of a copper collector, the process being conducted at a natural pH essentially determined by the ore composition and the quality of the water used to form the pulp, without addition of substantial amounts of alkaline or acid pH modifiers sufficient to change the pH.

Abstract: A process which is especially useful for effecting magnetic separation of magnetically attractable impurities from an aqueous clay slurry or suspension includes passing the suspension (42) through a porous, ferromagnetic matrix while applying a magnetic field to the matrix (10), on which impurities are collected, and thereafter regenerating the matrix by flushing collected impurities therefrom with a flush liquid (26), e.g. water. The improvement comprises, after discontinuing the passage of the suspension through the matrix, but before passing flush liquid therethrough, admitting a pressurized gas (68) e.g. compressed air, into the separator to displace suspension retained therein, and recovering the displaced suspension. In addition, flush liquid retained in the matrix after the flushing step may be displaced therefrom by the compressed air. By displacing the retained suspension from the matrix with compressed gas instead of flush liquid the retained suspension is not diluted and is recovered instead of sewered as in the prior art processes.

Abstract: The circuit carrier plate (4), typically part of a p.c.b. flat pack module (3), has a contact wire (5) soldered to its earth conductor. The length of the wire is determined by the distance between the module edge and the screening housing (11). The wire is at an acute angle to the screening housing wall, and pref. has a sharp edge at its free end. The screening housing is typically made of aluminium. The angle at which the wire is mounted ensures that when the module (3) is inserted (6) into the housing (1,2), the sharp edge of the wire end scrapes along the screening housing to give a good electrical contact. This is esp. necessary if the screening housing is protected by an insulating lacquer.

Abstract: An impact flowmeter utilizes a part cylindrical impact plate (6) mounted by a parallelogram strain gauge (14) from the top of a cylindrical housing (2) with which it is coaxial. Material to be metered enters the flowmeter through an inclined inlet tube (4) so as to impact the inner surface of the impact plate, and the horizontal reaction force from the plate is measured by the strain gauge. The flowmeter is simple to construct and can be made very compact, whilst the cylindrical surfaces of the principal components minimizes disturbances of the flow of material through the unit and thus provides good linearity.

Abstract: The invention aims to compensate for tolerances which occur in the interior construction of rail vehicles, using a floating floor construction and to allow a force-reducing relative displacement between the installation components which are permanently mounted onto the construction shell, such as seats, back panels, cupboards etc. and the floor, whilst excluding the penetration of moisture between the permanently mounted attachments or installed sections and the floor, which can be displaced in relation to each other. This is achieved by a corner profile (12), located between the floor plate (5) and the attachments or installed sections (18) that are permanently mounted onto the construction shell. Said corner profile runs both longitudinally and transversally in relation to said attachments and sections, forming a bearing surface (11) for the floor covering. One limb (13) of said corner profile forms the edge of the floor plate (5) which is to receive the floor covering and the other limb (15) is positioned so that it can be displaced in a longitudinal and transverse direction, in relation to the construction shell. The horizontal tolerance compensation can be absorbed by a flexible seal (17) which is fixed to the limb (15) and lies against the construction shell.

Abstract: The invention relates to a method and a device for producing oligomers and arrays of oligomers, whereby the synthesis procedure is expanded by an additional neutralisation step. This allows the protecting groups to be split without any carry over, enabling the oligomers to be de-protected in precisely defined positions on the support material. A novel microelectromechanic device is used for said method, which enables exact addressing on a support material in the form of mono or multi-dimensional arrays by the integration of reaction chambers (13) and several liquid metering elements (1, 4, 5, 7, 8) in a chip. The invention aims to provide a method of creating oligomers or arrays of oligomers which are positioned in a precise manner in a small area, which has a minimal error rate during the creation of oligomer sequences as a result of the neutralisation step and its corresponding prevention of the distribution of the de-protection agent to positions which do not require de-protection. In addition, the device aims to permit the rapid production of oligomers and arrays thereof in a cost-effective manner.
