Patent DE-4140440-A1 (DE)
Title: Nematode extracting appts., e.g. for obtaining worms from natural soil with sifting drums - uses soil samples of 5-10 grammes wet wt. in sifting drum 3.5 cm dia. and 3 cm high and soil samples of 50-100 gramme wet wt. in rectangular sieve 3.5 x 12 cm x 3 cm
IPC: G01N33/24
Filed: 1991-12-04
Abstract: The underside of the sieves is covered with plastic gauze, having a pore width of 0.5 mm, and on their outer sides, 1 cm distance from the under edge. A platinum wire is incorporated functioning as a cathode whilst the anode, with the sifting drum is fitted on a plastic pin, which is adjustably located in a clip spanning the drum and projects 1.5 cm deep in to the sifting drum. The rectangular sieves are positioned on a plastic strip, which runs longitudinally along a centre line in the sieve, and also can be lowered until it is 1.5 cm above the sieve base. With the insertion of the sieve in a funnel filled with water, a beaker glass or a petri dish, a current flows between the electrodes and through the soil sample. A transformer produces a voltage which is rectified to give 45 - 70 volt DC and a pulse generator with regulator produces a variable frequency between 5 and 100 Hz. The current flow forces a nematode migration from anode to cathode and in reaction time of 30 - 60 mins, 80 - 90 per cent of animals are found in collection vessels and can be supplied to evaluator. ADVANTAGE - Gives quick determination of free living nematodes for stock taking purposes. In period of 30 - 45 min., 80 - 95 per cent of nematodes have left soil sample.

Title: Determination of layer modulus of roadway construction materials - two loading plates of different sizes and at least three different loads are used with oscillating force device and sensors which detect response of roadway material
Inventor: EHRLER CHRISTOPH DR ING
IPC: G01N33/42
Filed: 1992-06-24
Abstract: Two loading plates of different sizes (32,46) and at least three different loads are used. A number of weights (14,16,18,20) are used to vary the force on the loading plates. Force is applied by an oscillating mechanism, and the resulting vibration is sensed by one or more sensors. A plate (30) forms the end wall of a housing (12) and contains the first loading plate (32). A second plate (42)  forms the opposite end wall of the housing and contains the second loading plate (46). A centrally-located magnet (54) exerts force pulses on one or other loading plate (32,46). The elasticity modulus E8 is defined as follows: E8=Ek + E0(10p)0.38 where Ek is the pressure-independent component, E0 is the pressure-dependent component and p is the pressure, the values of the components being derived from two or more measurements of the modulus. The loads on the plates are chosen such that the pressure-independent component is considerably larger when using the smaller plate than when using the larger one and the pressure-dependent component is the same for both plate sizes. A coupling medium, and especially fine sand or grit, is used between the plates and the road surface. USE/ADVANTAGE - For determining the layer modulus of roadway construction materials, deformation of roadway, or dynamic values characteristic of its load-carrying ability in the evaluation of road construction materials. High accuracy.

Title: Method for processing a serial digital data signal
Inventor: EBNER ANDREAS
IPC: H04N5/93
Filed: 1993-03-11
Abstract: To provide for reliable correction of quasistatic errors in serial digital data in television signals, the data signal separated from the television signal is compared with a data pattern corresponding to its data frame. When differences are found, a one- or n-step correction cycle is initialised in which the television signal with the data signal contained therein is equalised step by step in the analog signal domain. The data signal from each equalised television signal is separated and again subjected to a comparison. The said method steps are repeated until no further differences are found in the comparison step, but maximumally n times.

Patent DE-4310799-A1 (DE)
Inventor: MANG HARALD DR MED
IPC: A61M16/04
Filed: 1993-04-05
Abstract: An artificial respiration tube (10) which, at its lung end, has a pressure sensor (5) with electronic signal processing is used for continuously measuring the central respiratory tract pressure during assisted and controlled artificial respiration. Unlike the respiratory tract pressure measured in the artificial respiration equipment, the continuously measured central respiratory tract pressure allows artificial respiration to be better adapted to the mechanical properties of the lungs and thorax. In addition, the resulting pressure signal is suitable for controlling various functions of the artificial respiration equipment. As a whole, artificial respiration by means of a tracheal tube with an integrated electronic pressure sensor is safer and more confortable for the patient, without being more expensive.
