Title: Column for the magnetic separation of cells, cell aggregates and cellular constituents
Inventor: MILTENYI STEFAN
IPC: G01N33/50
Filed: 1987-06-24
Abstract: The invention relates to a novel column for the separation of magnetically labelled cells, cell aggregates or cellular constituents in aqueous suspension. For the fractionation, the column is exposed to an external magnetic field while the suspension runs through. Unlabelled elements pass through the column, while labelled elements remain suspended in the matrix. They can be eluted after removal of the magnetic field. The plastic coating on the inner wall of the column results in medium and cell or cell constituents being separated from the ferromagnetic matrix, which protects the constituents to be separated from damage. The coating stabilises the ferromagnetic matrix, and non-magnetic trapping sites are filled with plastic. Hitherto unattainable speeds and quality of separation can be achieved therewith at low expense.

Patent DE-3729971-A1 (DE)
Inventor: WUENNING JOACHIM DR ING
IPC: F27B9/36
Filed: 1987-09-08
Abstract: To provide for energy-efficient non-polluting heat treatment of workpieces (W) which, during heat treatment, emit oxidizable or combustible substances, hot gases are generated in a hot gas generating chamber (2) by a jet burner (5) emitting a flame jet. The hot gas generating chamber (2) is connected through a hot gas outlet (7) with a processing chamber retaining the workpieces, and a recirculating inlet (8) to receive the gases from the processing chamber, after they have been contaminated or received polluting combustible components. The hot gas generating chamber is, additionally, in communication through a duct or gap (4) with an after-burner chamber (3). The process is so controlled that the temperature in the after-burner chamber is maintained sufficiently high to provide for complete combustion of any oxidizable components, and the volume of the after-burner chamber, including the gas passed thereto, is so controlled that a dwell time of the gases therein will obtain which is sufficiently long to provide for said complete combustion. Typical dwell times are 1-2 seconds. A closed gas circulating loop (9) between the hot gas generating chamber (2) and the processing chamber (1) is established, the throughput to which can be controlled, for example by a throttling arrangement (13, 130), based on sensed temperature by temperature sensors (12, 15) which then control the throughput of hot gases in the closed loop and the fuel and air supply to the burner.

Patent DE-3828856-A1 (DE)
Inventor: BREITENSTEIN OTWIN
IPC: G01R27/26
Filed: 1988-08-25
Abstract: For detecting small variations in capacitance in a specimen 3 under test, a HF generator 1 supplies HF current through a quadruple balun transformer 2 to a parallel resonant circuit including the specimen 3, a capacitance diode 5 and an inductor 7, and a pre-amplifier 9 is connected to a phase sensitive rectifier (not shown) to produce an output representing capacitance variation of the specimen 3. Bias voltages U1, U2 are applied to the specimen 3 and the capacitor 5 and a compensating HF current is applied to the pre-amplifier 9 with 180 DEG phase shift via FET 8 controlled by a voltage U3. A gate 11 under the control of U4 switches the input of pre-amplifier 9 to compensate for relaxation time effects of the specimen 3. Balance of the apparatus is achieved by firstly applying a control voltage U4 to FET 11 to reduce the gain of pre-amplifier 9. Control voltage U5 is then adjusted to achieve balance. <IMAGE>

Title: Symbol clock and carrier phase synchronisation method for coherent digital signal receivers with multi-dimensional signal representation
Inventor: WEILING LIU DIPL ING
IPC: H04L27/233
Filed: 1989-02-10
Abstract: For carrier-modulated digital signal transmission methods, a novel method for joint estimation of the carrier and symbol clock in receivers of this type is proposed, in which receivers the received signal and all possible received user data signals are represented as linear combinations of a plurality of pairs of time-limited sine and cosine functions with different deviations from the carrier frequency. For this purpose, angle differences between the received signal and the user data signal estimated in the receiver detector are calculated for the individual base function pairs. Their mean value represents an optimum estimation of the carrier phase angle difference, while, in order to estimate a symbol clock shift, only these individual phase angle differences need to be weighted with the reciprocal values of the intervals between the associated base function pairs in the mean value formation. Instead of the angle differences, it is also possible to use complex quantities whose angles represent these phase differences. To determine the symbol clock shift, these complex, conjugated quantities are then to be brought into the mean value formation for one direction of the deviation of the frequency of the base signal pairs from the carrier frequency.
