Title: Operating method for ultrasound image system with field and/or array of converter elements
Inventor: SEYED-BOLORFOROSH MIR SAID
IPC: G01N29/44
Filed: 1997-12-19
Abstract: The method includes the step of emitting a first ultrasonic wave with a first frequency range centered around a first transmission frequency, by exciting selected converter elements during a first time interval, whereby the first ultrasonic wave is focused in a focus point. A second ultrasonic wave with a second frequency range centered around a second, different frequency, is emitted by exciting selected converter elements during a second time interval which follows immediately the first interval, whereby the second ultrasonic wave is focused in the same focus point. A first and a second complex signal pair are formed from a first and a second received ultrasonic wave which was derived from the respective share of the first or the second emitted ultrasonic wave which was reflected by strew elements in a focus zone to selected receiving converter elements. The first and second complex signal pairs are filtered through the same filter transmission functions, and are added to form a third complex signal pair. An envelope of the third complex signal pair is formed, and an image vector is displayed, which is a function of the envelope, as well as the third complex signal pair.

Patent DE-19817786-A1 (DE)
Inventor: FEILITZSCH FRANZ V
IPC: G01J5/06
Filed: 1998-04-21
Abstract: The invention relates to a microcalorimeter or a group of microcalorimeters, comprising a sensor component (1, 2) consisting of a thermometer (1) with a superconducting material and an absorber (2) which is thermally coupled to the thermometer, a cooling device (30), a heating device (20) and a read-out device. The cooling device and the heating device are thermally coupled to the sensor component separately from each other and at least the cooling device is thermally coupled to the sensor component across its surface. This design allows for the adjustment of a large dynamic area with minimum calorific output and for the cooling device and heating device to be optimized separately, resulting in improved energy resolution or signal acceleration. This type of microcalorimeter is used, for example, in material analysis or quality assurance by X-ray fluorescence analysis, preferably in the semiconductors industry, but is also suitable for the determination of molecules in biotechnology.

Title: Recovering PVC from contaminated waste is achieved by mixing with swelling agent followed by separation in cyclones and drying to recover pure plastic for re-manufacture, including useful pure non-PVC plastic stream
IPC: B29B17/02
Filed: 1998-08-21
Abstract: Swollen, softened and precleaned comminuted mixture enters a closed system under pressure and is transferred to hydrocyclones in series, dense materials, e.g. sand and metal, are centrifuged out. Swollen PVC particles and light contaminants flow over, to size classification.  The mixture enters a closed system under pressure and is transferred to hydrocyclones. Dense materials, e.g. sand and metal, are centrifuged out. Swollen PVC particles and light contaminants flow over, to size classification. The flow of smaller particles, including swollen PVC particles and other, smaller plastic particles, enters the second hydrocyclone where PVC particles are separated in the downward flow.  An Independent claim is included for the plant carrying out the process.  Preferred features: The mixture is supplied by a pump for dense materials (12) to the hydrocyclones, at 1.5-2 bar. The feed spins at differing rates in the hydrocyclones. Swelling time of PVC in the mixture is controlled. Precomminuted mixture first enters a screw conveyor (9) with the swelling agent. Residence time is controlled by screw speed. Additives, especially plasticizer in the PVC of the mixture, are evaporated and/or desorbed, and the separated pure PVC is sent on. The PVC passes through a series of drying screw conveyors (28a, 28b, 29a-n) for this purpose. One is heated, one evacuated. Heat is conveyed by a thermal medium, recirculated to a heat exchanger (19). A heavy fraction dryer is similarly heated. Swelling agent extracted from the evacuated or heated dryer, is condensed in a heating jacket of at least one of the evacuated screws. Pure PVC is collected in a closed gas-tight vessel (41), which is ventilated for complete desorption. A further variant of the process is described, involving fluidized bed separation. The process is continuous.
