Patent DE-4128713-A1 (DE)
Inventor: MUELLER ANDREAS DIPL ING
IPC: H04L27/26
Filed: 1991-08-29
Abstract: The invention relates to a method and an arrangement for determining, at the receiver end, the carrier frequency offset between transmitter and receiver which is needed as controlling variable for the automatic frequency control of the receiver. In this method, a test signal is regularly radiated at the transmitter end and analysed by an arrangement at the receiver end. A class of test signals is set up which are suitable for determining the carrier frequency offset and at the same time allow the channel step response to be estimated which allows the synchronisation achieved with the zero symbol to be improved. <IMAGE>

Title: Plastic parts prodn. from thermoplastics - involves treating the thermoplastic powder or granules with low-temp. plasma before the final moulding process
Inventor: LIEHR KLAUS-DIETER DIPL ING
IPC: B29B13/08
Filed: 1991-12-18
Abstract: Prodn. of moulded thermoplastic prods. comprises: treating the plastic powder or granules (I) with low-temp. plasma before the definitive moulding process. Also claimed is an appts. for this process, comprising a vacuum chamber connected with a vacuum pump via line, a rotating drum inside the chamber with holes, at least near the drum axis in the end faces to enable gas exchange, and a gas feedline. Pref., (I) is subjected to plasma activation, esp. to increase hydrophilicity for painting, bonding, printing, foaming or flocking, using O2, N2, O2/N2 mixts., N2O, CO2, NH3, H2, CF4, SF6, NF3, or mixt. of CF4, SF6 or NF3 with O2 and/or inert gas (pref. He or Ar) as discharge gas. Or the hydrophobic nature of (I) can be increased to make it unreceptive to the above processes, using F-contg. gases, esp. CF4, SF6 or NF3. Treatment is carried out in low-pressure plasma at 1-300 Pa and power density 0.3-30 W/dm3, for 1 second - 15 minutes Plastics with little or no chain branching, e.g., polyethylene (PE), can be pref. crosslinked using N2, H2 or inert gas low-temp. plasma. The crosslinked material is pref. embedded to improve notched impact strength, heat resistance, etc., and the process is carried out at pressure and power density as above for 1-120 minutes Layers of polymer can be pref. deposited on (I) from low-temp. organic plasmas, or mixed with (I) to produce composite materials. The mechanical stability of PE can be pref. improved by using ethylene or other volatile hydrocarbon as discharge gas, pref. with addn. of oxygen to improve hydrophilicity (see above), or a mixt. of 2-chloroacrylonitrile and I2 can be used to confer antistatic properties. Process conditions are 1-200 Pa and 1-100 W/dm3 for more than 1 minute. USE/ADVANTAGE - The process enables the effects normally obtd. by low-temp. plasma treatment of plastic mouldings (e.g., improved thermal, mechanical and other properties, surface modification to improve paintability, printability, adhesion and metallising properties, etc.), to be standardised for final mouldings of any shape or size, without specially adapted plasma treatment plants. The effects of plasma treatment are retained after subsequent injection moulding, blow moulding or other processing.

Patent DE-4203202-A1 (DE)
Inventor: KRAUSE FRIEDEMANN DR
IPC: G01N21/359
Filed: 1992-02-05
Abstract: A process for analysing a medical sample, especially of a bodily fluid, using an analysing device, in which a test fluid containing an aliquot part of the sample and reagents is in a cell and the temperature of the test fluid in the cell is determined. In order to determine the temperature of the test fluid contactlessly and directly, the optical absorption of a calibration fluid is determined in a temperature calibration stage at at least two wavelengths in the near i/r range at various temperatures in order to obtain a set of calibration data concerning the temperature dependence of the optical absorption and in a temperature measurement stage the optical absorption of a test fluid of unknown temperature is measured at the same wavelengths and its temperature found by comparison with the absorption data obtained in the measurement stage.

Title: Relay with vibration damper between spring stirrup and contact bridge - maintains contact by max. compression of damping wire cushion which allows practically no acceleration of spring
Inventor: ELSNER NORBERT
IPC: H01H50/30
Filed: 1992-02-10
Abstract: The moving contacts (5, 7) arranged at opposite ends of a bridge (8) cooperate with fixed contacts (4, 6).

Title: Process and apparatus for dewatering sludges
Inventor: RUMOCKI ANDRZEJ DR ING
IPC: C02F11/12
Filed: 1993-05-06
Abstract: In order to achieve a higher dry matter content in sewage sludges with lower expenditure in terms of apparatus and energy in comparison with long-time driers, it is proposed to heat externally the sewage sludge within a conventional sewage sludge centrifuge in a region between inlet zone and discharge zone. The sludge temperature within the centrifuge and the magnitude of the mechanical load of the organic cells of the sludge within the centrifuge are matched to each other in such a way that on the one hand the viscosity of the capillary water stored in solids capillaries of the sludge is reduced by the heating and on the other hand the organic cells of the heated sludge which are filled with cell water still remain closed. <IMAGE>
