Patent EP-0036577-A1 (EP)
Inventor: SACHS BERTRAM
IPC: G10K11/34
Filed: 1981-03-12
Abstract: Die Erfindung bezieht sich auf ein Ultraschall-Array, mit einer Anordnung der Wandlerelemente in Zeilen und Spalten, wobei die Wandlerelemente beidseitig an gegenüberliegenden Kontaktflächen kontaktiert und sowohl den Kontakten der einen Kontaktfläche als auch den Kontakten der anderen Kontaktfläche Schalter zugeordnet sind, die zur Einstellung vorwählbarer Sende- und/oder Empfangsflächen aus Wandlerelementen während eines Sende/Empfangs-Zyklus, insbesondere zum Zwecke der dynamischen Fokussierung, dienen. Ziel der Erfindung ist es, ein Ultraschall-Array aufzubauen, das mit optimal niedrigem Aufwand an Schaltern auskommt und das dadurch gegebenenfalls auch den Übergang auf kontinuierlich variierte Apertur zuläßt. Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß Wandlerelemente (2) mit ihrer einen Kontaktfläche in Richtung der Zeilen (Z1 bis Z3) und mit ihrer anderen Kontaktfläche in Richtung der Spalten (SP1 bis SPN) zu Gruppen zusammenkontaktiert sind und daß jeder Zeilengruppe höchstens ein einzelner gemeinsamer Zeilengruppenschalter (ES1 bis ES3 bzw. ES) und jeder Spaltengruppe höchstens ein einzelner gemeinsamer Spaltengruppenschalter (SS1 bis SSN) zugeordnet ist. Ein Übergang auf kontinuierlich variable Apertur ist auf einfachste Weise möglich, wenn als Sende- und/oder Empfangsschalter kontinuierlich änderbare Schaltelemente, wie steuerbare Widerstande od. dgl., eingesetzt werden.

Abstract: A defatted meal originating from oil-bearing seeds such as soybean, rapeseed or cottonseed is treated with an aqueous solution to solubilise protein present in the meal. If desired any insoluble carbohydrates present can be removed. The pH of the resulting slurry or clarified solution is lowered to between 2.0 and 3.0 and maintained to dissociate the protein into its subunits. The slurry or clarified solution is heated to cause aggregation of the subunits and its pH is then raised prior to ultra-filtration. A membrane is employed which retains the proteinaceous material and yet allows salts and low molecularsugarto permeate.

Abstract: The invention concerns the detection of cantaminant in a stream of gas. Previous methods have either been insufficiently sensitive or have been slow and needed skilled opera-- tives. The present invention allows speedy operation with relatively unskilled operatives. 
     A piezo electric crystal oscillator (1) is allowed to oscillate for a known period of time and the number of oscillations is counted. For a known time the crystal is exposed to contaminant, and is then allowed to oscillate again for the same period of time as before and the oscillations again counted. The difference in number of oscillations is a measure of the mass of contaminant deposited on the crystal (1). The period of oscillation of the first crystal is determined by a second matched crystal oscillator(2) in which the crystal is exposed to the same environment but not to contaminant. 
     The apparatus has the advantage of being self-zeroing, and the exposed crystal (1) does not need cleaning after each use. The invention has special application to the testing of medical gases, for example oxygen and nitrous oxide.

Abstract: This invention relates to a structure for supporting a power lead (3) connected to a superconductive field coil (2,6) and refrigerant supply and discharge pipes (7, 11) in the hollow shaft (14) of the superconductive rotor. A plurality of spacers (15) for holding the power lead (3) and the refrigerant supply and discharge pipes (7,11) are fitted in a supporting sleeve (16), and fixed (at 19) from the outer peripheral side of the supporting sleeve, the supporting sleeve itself being fixed in the cavity of the hollow shaft (14) r by centering screws (17). Since the fixing work can be made from the outer peripheral side by means of the structure stated above, it is possible to fix the leads and pipes to the inside of the shaft easily and rigidly, and to avoid the generation of vibration so as not to seriously damage the stability of the superconductive state of the rotor.

Abstract: A thin film light modulator (50) for use in an electro- optic line printer (11). A light valve utilizes a thin electro- optic film (54) on a substrate (52) with the index of refraction of the film being higher than the substrate so that the light can be guided in it. A laser beam (48) is caused to be guided in the film, the beam expanding sideways so that a sheet of collimated light is provided. This light is guided beneath an array of electrodes (58), consisting of an extended set of individually addressed metal fingers. The light diffracted by the electrode set is reimaged onto the recording medium (14), with the zero order diffracted light blocked out, so that each electrode pair acts as a light modulator for one picture element on the output. Alternatively, the zero order is reimaged and the higher order diffraction components are blocked out. By applying each bit of a serial stream of data to the corresponding electrode, a line recording is achieved.

Abstract: An ultrasonic Doppler flowmeter is disclosed in which a received signal processing part (20) includes a reference signal generator (210,212) for generating a reference signal corresponding to the magnitude of a received signal, and a comparator (214) for comparing the received signal with the reference signal. The reference signal varies in accordance with the magnitude of the received signal, and further may possess a hysteresis width corresponding to the output of the comparator. Therefore, a noise signal is effectively removed from the received signal at the comparator, and only a Doppler shift frequency is detected.

Abstract: An arrangement for extended sedimentation basins and similar installations for removing deposited sediment or other sludge from the bottom of the basin, comprising a traverser (9) which is arranged to be moved from a starting position, normally in conjunction with one short end of the basin, to a receiving end, for example to a sludge hopper or the like, on a path (8) arranged in the basin (1) at such a depth below the water surface (2) that the traverser (9), transported along the path is also located completely below the water surface (2). At the front end and rear end the traverser has one or several scrapers (19) and (20) respectively, or corresponding cleaning devices which extend essentially across the width of the basin (1) and which in the effective cleaning position, when the traverser is moved towards the said sludge hopper (7) or the like, are positioned essentially vertical in respect of the bottom (3) of the basin. The said scrapers (19, 20) are furthermore arranged so that they can be swivelled upwards from the said essentially vertical operating position by means of a cable (25) to an essentially horizontal transport position (19', 20'), when the traverser is to be moved back in the opposite direction towards the starting position. The same cable is also employed for pulling the traverser to and fro in the basin. The arrangement can also be supplemented by a unit for surface scraping, in that an upper scraper (60) mounted on the bridge is arranged to adopt a working position in the surface layer of the basin by causing the bottom scrapers to change their working position. A safety device is so designed that the cable drive ceases if the cable tension drops considerably and if the cable tension does not revert to its normal value within a certain period of time.

Abstract: The invention relates to a process by means of which disturbing interference phenomena can be suppressed in optical systems. Such phenomena occur whenever two adjacent components, for example a mask (8) and a substrate (9) of an alignment apparatus, are struck by monochromatic radiation and deflected or reflected radiation interferes. The process is based on the principle of moving the mask (8) and the substrate (9) relative to one another in such a way that the interference pattern at the location of the detector arrangement (12) is "smeared" on average in space and/or time and forms only a non-disturbing background. Furthermore, a process and device are described for aligning a mask (8) and a substrate (9) using devices (13 to 16) for carrying out a rapid, periodic relative movement of a substrate (9) with reference to the mask (8) (Fig. 1). <IMAGE>
