Patent DE-4019942-A1 (DE)
Inventor: GENG MANFRED
IPC: A01B73/04
Filed: 1990-06-22
Abstract: The invention is intended to improve the functioning of a two-rotor windrower which can be suspended on a tractor and the windrowing rotors of which are arranged in a staggered manner. The feature of such windrowers is that they do not pick up a strip of crop when they go round a bend in one direction. This defect is eliminated in that a two-wheeled undercarriage (1) is provided in such a way that one of its running wheels (6) is arranged in the interspace between the two windrowing rotors (10, 12). This position of the undercarriage (1) makes it possible to articulate the leading windrowing rotor (12) laterally on the undercarriage (1) and the trailing windrowing rotor (10) on the rear side of the undercarriage (1). This arrangement allows the windrowing rotors (10, 12) to be brought into an especially favourable transport position. <IMAGE>

Inventor: SCHULMEYER HANNS-LUDWIG DIPL I
IPC: B61L5/18
Filed: 1991-04-05
Abstract: A device for cold filament testing signal lamps (L) which are located in the exterior system of a signal box and are fed via lamp transformers (LT). For the purpose of testing, the inductive resistor of the primary winding of the lamp transformer is evaluated. The primary winding is connected for this purpose in a measuring circuit which extends from a measurement voltage source (QM) via the cable conductors used for feeding lamps, and contains an inductive measuring resistor (W). The current flowing in the measuring resistor or the voltage dropping across the measuring resistor is evaluated by comparison with the corresponding measurement variable occurring when the measuring resistor is fed directly with the measurement voltage. <IMAGE>

Title: Affinity chromatography for heterogeneous immunoassay or preparative purificn. - using lyotropic liq. crystalline stationary phase, and organic solvent or reverse micellar mobile phase
Inventor: MIETHE PETER DR
IPC: G01N33/558
Filed: 1991-04-09
Abstract: In an affinity chromatography process using an organic solvent mobile phase, a lyotropic liq. crystalline (LLC) system (or a microemulsion gel, i.e. an LLC/microemulsion gel, or its mixt. with an inert carrier) is used to immobilise binding-active substances (A). This system coexists with an organic solvent or reversed-micellar phase in which the binding partner is dissolved or solubilised. Quantification or further processing is carried out in this mobile phase, or after release from the stationary phase, or in the stationary phase (after this has been converted to liq. form by addn. of other substances, application of pressure and/or by heating). USE/ADVANTAGE - The method is used for (1) performing heterogeneous immunoassays (esp. ELISA) or other binding tests or (2) preparative purification. Suitable (A) are antibodies, antigens, ligands, receptors or other biological binding partners and their conjugates, esp. those of poor water solubility. Analytes are selectively sepd. from the solvent phase with high binding capacity, simply and reproducibly, then converted back to a highly conc. mobile phase without an elution stage (so the detection limit is improved).
