Abstract: Die Erfindung bezieht sich auf eine Kammer für die Behandlung von Zellen im elektrischen Feld. Derartige Kammern besitzen einen Raum zur Aufnahme der Zellsuspension mit einer zwischen zwei Elektroden liegenden Zone, innerhalb der die Zellen im elektrischen Feld ausgesetzt werden. Das Ziel der Erfindung, eine leicht handhabbare Kammer zu schaffen,wird durch eine Kammer gelöst, bei der die Zone - bis auf eine Einfüll- bzw. Ausfüliöffnung für die Zellsuspension - von äquidistant einander gegenüberliegenden, koaxial oder konzentrisch angeordneten Oberflächen der Elektroden begrenzt ist. Bei einer besonderen Ausführungsform der Kammer ist die erste Elektrode als Innenelektrode mit zylindrischer und die zweite Elektrode als Außenelektrode mit nach innen gerichteter zylindrischer Oberfläche ausgebildet; so daß die Zone ein zylindrischer Ringraum ist. Die eine Stirnseite des Ringraumes ist nach außen offen, während die andere Stirnseite des Ringraumes in einen axialen Kanal mündet, der in der Innenelektrode verläuft und in die Einfüllöffnung mündet. Diese besteht in einem sich nach außen hin erweiternden Innenkonus, dessen Abmessungen so gewählt sind, daß in ihn eine Pipette eingeführt werden kann.

Abstract: This invention relates to a non-intumescent, non-char farming, endothermic. essentially inorganic, flexible, fire- protective sheet material. The flexible sheet is made of a compositon comprising:
     a) an inorganic fiber, such as fiberglass and alumino-silicate refractory fibers;   b) an organic polymer binder, such as an acrylic resin; and   c) an inorganic endothermic filler, such as alumina trihydrate.   
     The weight ratio of organic to inorganic constituents is less than about 0.10, and the weight ratio of inorganic endothermic filler of part (c) to inorganic fiber of part (a) is in the range of just greater than 5.0 to 50. This sheet is a useful fire barrier wrap for conduits and cable trays in building construction, which provides excellent fire protection, and the current capacity derating of cables is significantly less with this new fibrous sheet than it is in the case of known fire barrier sheet materials.

Abstract: A method for the manufacture of cored construction products from dry particulate materials is proposed which involves feeding the materials into a vibration mould so as to bring the same into pre-compacted condition, and subjecting the materials when in such condition to pressure so as to effect compaction thereof. After compaction, a free standing surface of the material is impregnated with a setting liquid.The vibration is of such frequency and amplitude as to bring the individual particles into substantially uniform closely spaced disposition, the subsequent application of pressure bringing the material into a compacted state without any substantial re-arrangement or crushing of the particles.Apparatus for use in practising the method is disclosed.

Abstract: An alignment apparatus wherein a wafer having a wafer target thereon and a reticle having a reticle target therethrough are aligned to each other. An alignment image is formed on the wafer, and the wafer and reticle are scanned relative to the alignment image. The alignment image has a linear extent normal to the scanning direction which is longer than the wafer target so that a portion of the alignment image is reflected by the wafer. The portion of the alignment image reflected by the wafer is reimaged onto the reticle target. Collecting means are provided to collect light from the alignment image that is backscattered by the wafer target as the wafer target is scanned past the alignment image. Two detectors are provided: one to detect the backscattered light, the other to detect light which passes through the reticle target. The output from each of the detectors is compared to determine any misalignment.

Abstract: An electronic air-fuel ratio control apparatus in an internal combustion engine provided with an oxygen sensor emitting an output voltage in response to an oxygen concentration including oxygen in nitrogen oxides in an exhaust gas from the engine controls an air-fuel ratio of an air-fuel mixture by a feedback correction-control based on a fuel injection quantity in an on-off manner. By using the oxygen sensor having the nitrogen oxides-reducing catalytic layer, the detection of a theoretical air-fuel ratio is performed on a richer side comparing with the output on the detection of a theoretical air-fuel ratio by an oxygen sensor without the nitrogen oxides-reducing function and is not changed even though the nitrogen oxides concentration changes. Accordingly the feedback air-fuel ratio control effects to decrease the amount of nitrogen oxides so as to stabilize the air-fuel ratio control. A first target air-­fuel ratio for the air-fuel ratio feedback control is changed to a second target air-fuel ratio which is richer than the first target air-fuel ratio when the high nitrogen oxide concentration in the exhaust gas is detected or which is leaner than the first target air-fuel ratio when the incompletely burnt component concentration in the exhaust gas is detected.

Abstract: The invention relates to a securing device for assembled tubular scaffolding joints, together with a level-regulating means. For reusable scaffolding units it is a desirable aim to be able to relocate units which are as large as possible in order to minimise setting-up and shuttering times. Sleeve joints in scaffolding units have to be secured during relocating, for which purpose the invention proposes a universal solution for a securing device. The securing device according to the invention is distinguished in that it is fitted in the inaccessible, protected area of the hollow cross-sections and the individual parts, such as insertable end plates, spindles, butt joint connectors and the like are held together resiliently in one unit, so that infinitely variable adjustments can be made even under load. <IMAGE>
