Title: Filter bank for frequency multiplexing or frequency demultiplexing of channel signals
IPC: H03H17/06
Filed: 1988-10-22
Granted: 1989-12-07
Abstract: The invention relates to a filter bank for the frequency demultiplexing or multiplexing of L channel signals, consisting of L transversal filters (non-recursive filters, finite impulse response filters (FIR)), with complex-valued coefficients, for real-valued input signals and with complex-valued output signals or conversely, with a sampling rate which is reduced or, respectively, increased by the factor M at the output, the L filters being implemented by a cascading of a number of filters, the sampling rate being reduced or, respectively, increased by factor Mq in each cascade stage, and is characterised by the fact that a complex multiplier is in each case inserted in front of the same cascade stage in the individual filter cascades, which multiplier multiplies the complex-valued output signal of the filter of the preceding cascade stage with the complex signals of a complex carrier oscillation. Such filter banks are predominantly used for multiplexing or demultiplexing single FDM channels in transmultiplexers, for example in satellite engineering. The aim of the invention is a unification of the overall arrangement of the filter bank by reducing the multiplicity of different filters or different filter coefficients. The result is an improved characteristic with respect to design, test, production and better possibilities for introducing redundancy (especially important in the satellite application). In many cases, a ... is additionally ... Original abstract incomplete.

IPC: B23Q1/25
Filed: 1992-05-09
Granted: 1993-07-29
Abstract: A circular saw with a saw blade (12) angularly adjustable in a rotatable supporting table (13) is to be equipped with a tilting suspension which works trouble-free and does not displace, as a function of the tilting, the chord (15) of the saw-blade working section (14) projecting through the supporting surface (16). For this purpose, a triangular link (21) hangs with its base angles on pendulum bars (24, 25) at a distance below the supporting surface (16). In the vertex angle (34) of the triangular link (21), a stay (30) rigidly connected to the bearing (19) of the saw blade is suspended in an articulated manner. The stay (30) at the same time serves as a parallel bar of a parallelogram guide (35), the longitudinal bar (36) of which is the rigid extension of one (24) of the two pendulum bars (24, 25). The connecting leg (32) from the end of this pendulum bar to the vertex angle (34) of the triangular link (21) is at the same time one of the two transverse bars of the parallelogram guide (35). The latter, during lateral displacement (under pendulum-induced lifting) of the triangular link (21), causes pivoting of the saw blade (12) about the vertex angle (34) and thus tilting of the working section (14) about the chord (15) immovable in the supporting surface (16). <IMAGE>

Title: Immunoassay using test strip with immobilised antibody - based on displacement of tracer from antibody by analyte, esp. for determn. of pollutants
Inventor: BEHNKE ANDREAS
IPC: G01N37/00
Filed: 1992-09-04
Granted: 1994-03-24
Abstract: Immunoassay for determn. of an analyte (5) in a sample, using a test strip (1) of absorbent material with a zone in which an analyte-specific antibody (3) is immobilised, comprises (a) binding a 'tracer' (4) to the antibody, where the tracer is an analyte conjugate (6) capable of binding a labelled reagent, and where the antibody has greater affinity for the analyte than for the tracer; (b) contacting one end of the strip with a test soln. contg. the sample and the labelled reagent (9); (c) allowing the test soln. to migrate along the strip under capillary action, so that the labelled reagent binds to the tracer and the tracer is displaced from the antibody by the analyte; (d) washing the strip; (e) contacting the strip with a developer soln. contg. a signal-producing system capable of producing a detectable signal in the presence of the label; and (f) comparing the signal with standards. Also claimed is an assay as above comprising (a) binding a tracer to the antibody, where the tracer is an analyte analogue which is linked to a dye or is capable of binding a dye present in the test soln., and where the antibody has greater affinity for the analyte than for the tracer; (b) contacting one end of the strip with a test soln. contg. the sample (and opt. the dye); (c) allowing the test soln. to migrate along the strip under capillary action, so that the analyte displaces dye-labelled tracer from the antibody; and (d) comparing the signal produced by the dye with standards. Also claimed is a device for performing the first assay. The antibody is immobilised by covalent, adsorptive or hydrophobic/hydrophilic interaction. The strip is made of paper or a membrane material, opt. with a plastics support. The detectable signal is a colour change in the antibody zone, produced by a chemical or enzymatic reaction or by a coloured particle or molecular complex present in the labelled reagent. The test strip may have a second antibody zone downstream from the first, in which the immobilised antibody has greater affinity for the tracer than the first antibody or has affinity for another component of the reaction system. USE/ADVANTAGE - The assays may be used for determn. of low-molecular-wt. analytes, esp. pollutants (e.g. pesticides or their metabolites) in soil, water or air samples. Only one antibody is required; the strip has only one antibody zone (no capture zone is needed); the antibody is, in many cases, stabilised by the tracer, so strips with preformed antibody-tracer complex may be stored for long periods; no reactions take place in the test soln., so controlled conditions are not required; only the amt. of antibody needs to be fixed (other reagents may be used in excess).

Abstract: The invention concerns the manufacture of hollow plastic articles by inflating a preform (4) in a blowing mandrel. The aim of the invention is to reduce the so-called cycle time - the time interval between a preform (4) entering the blowing mould (1, 1') and the next preform (4) entering the same blowing mould (1, 1') - compared with prior art methods in which the initially open mould encloses the preform along the appropriate length when the preform is extruded from the blow-moulding nozzle, the mould then being transferred to a second station, adjacent to the tubular body receiving station, where the preform is inflated by insertion of an inflation and sizing mandrel. This aim is achieved by introducing the inflation gas into the preform, received by the mandrel, while the preform is being transferred from the first station, in which the tubular body is received, to the second station, in which release is effected.
