Title: Trolley-mounted instrumentation for testing air filters
Inventor: HEINDL ERICH
IPC: G01N15/08
Filed: 1996-12-19
Abstract: The unit tests filters used for air cleaning. It passes a flow of ambient air (3) containing impurities through a test filter, taking a sample before and after so doing. An instrument measures and records physical data from the air stream. A novel feature is a trolley (1) carrying the equipment.  Also claimed is the method, of which an essential feature is the use of only ambient air in the test, which is therefore only contaminated with naturally-occurring impurities (or those peculiar to the specific environment). Preferably, each typically has a concentration below 1  mu g/m<3>. The section taking the samples comprises two separately-operated air scrubbing stations. The trolley has rollers (2), mounted for pivoting and braking. The test filter is fixed by standardised fastenings in a filter chamber.

Filed: 1997-03-13
Abstract: A conventional circuit for blocking a semiconductor switching device (7) on overcurrent, the semiconductor switching device (7) having at least one continuously driven semiconductor switch (9), comprises a driver circuit (11), which has a driver stage (12) for each semiconductor switch (9), a control pulse generator (10) for producing control pulses (P1 to P6), which are fed in operation to a control input of the semiconductor switching device (7) via the driver circuit (11), and a monitoring device (34), which measures the current (I) flowing through the semiconductor switching device (7) and, when an overcurrent occurs, generates a fault signal (E), which initiates blocking of the semiconductor switching device (7). When the semiconductor switching device is being blocked, a high overvoltage can occur therein, possibly leading to destruction of the semiconductor switching device. In order to reduce, with little outlay, the overvoltage in the semiconductor switching device during blocking thereof, provision is made such that the operating voltage (U) of the driver circuit (11) is arranged to be switched over briefly by the fault signal to a lower, interim value corresponding to a lower current (I) through the semiconductor switching device (7) and then, within the maximum permissible duration for loading the semiconductor switching device (7) with an overcurrent, to be switched off completely.

Title: Flow stirrer for pipe carrying highly viscous fluid
Inventor: GOOSSENS GUNTER DIPL ING
IPC: F15D1/02
Filed: 1997-03-20
Abstract: The system reduces the range of residence times of laminar flowing media. It is used especially with highly viscous fluids, e.g. molten mixtures of polymers. The system uses a flow stirrer and divider which brings fast-moving fluid from the centre of a pipe into contact with the walls. The flow stirrer moves slow-moving fluid in contact with the walls into the centre of the pipe. The mixing device consists of a ring (5), which may be welded into the pipeline, and which carries integrally-formed vanes to mix up the laminar flow and promote turbulence.
Patent DE-19718652-A1 (DE)
Title: Liquid chromatography apparatus with improved separation
IPC: B01D15/08
Filed: 1997-05-02
Abstract: This original apparatus improves separation in liquid chromatography. A novel feature is the continuous taper in the direction of flow, over the lower section of the separation column. Flow is accelerated here, compressing and stabilising the packing (matrix MX). There are connections at either end of the column, each with two openings, but which differ in construction. That on the inlet and distribution side has a large dead volume, expanding conically. In this, a sieve plate is mounted to allow movement, this being held against gravity by retaining springs during operation. The connection at the outlet side has a fixed sieve plate with funnel collecting eluate. This has an outlet, with at least one further opening at the upper edge, which can be closed.

Title: Through-gas return channel in cylinder head and block of engine
Inventor: KASAHARA SATOSHI
IPC: F01M13/00
Filed: 1997-10-29
Abstract: Through-gas entering between the piston (12) and cylinder lining (52) is fed into a venting chamber (80) formed by a deflection plate (74) within the cylinder head cover (26) in a continuous passage completed by a channel-forming element (84) without interruption.

Patent DE-19754482-A1 (DE)
Inventor: OLEK ALEXANDER
IPC: C12Q1/6886
Filed: 1997-11-27
Abstract: The invention relates to a method for characterising, classifying and distinguishing tissues and cell types, for predicting the behaviour of tissues and groups of cells, and for identifying genes which have altered in their expression. Said method is characterised in that the base cytosine (not 5-methyl-cytosine) in a genomic DNA taken from any tissue sample is converted into uracil through treatment with a bisulphite solution. Fractions of the genomic DNA which has been treated are amplified by using very short or degenerated oligonucleotides, and the remaining cytosines of the amplified fractions are detected by means of hybridisation or polymerase reaction. The data generated from the analysis and automatically transferred to a processing algorithm is then used to draw conclusions as to the phenotype of the cell material which was analysed.
