IPC: G01N35/10
Filed: 1990-07-09
Abstract: An apparatus for processing liquids comprises a hollow reactor compartment (1) which is open on both sides and which is detachably connected to a receptor end (3) of a tube system (4,9). A portion (3,4) of the tube system is fixed to a rotor arm (5) which can be rotated in a circle and moved up and down. Another portion of the tube system is coupled to a metering syringe (12) which serves for drawing in or ejecting fluids into or from the reactor compartment (1) and/or the tube system (4). A plurality of process stations such as bottles (23) containing reagents or solvents, or waste containers, or ovens (24), or a park device for receiving the reactor compartment (1) are arranged on a circular tray (22) such that they can be accessed by the reactor compartment (1) or, if the reactor compartment has been detached and is parked in the park device, by the receptor end (3). The invention can be used, for example, for automatic protein sequencing, whereby the proteins to be sequenced are held in place by a matrix (2) in the reactor compartment (1).

Abstract: The support member for end windings (9') is used for electrical wire windings (9) in small transformers and inductors. The iron jacket (8) which encloses and holds the winding is arranged on a mounting plate (10). The mounting plate (10) and iron jacket (8) are thermally conductively connected to one another. The support member has an I-shape when viewed from the end and a U-shape when viewed from the side. The side pieces (2, 3) which are connected by means of the web of this support member hold the end winding (9') between them. The side pieces (2, 3) and web of the support member are produced integrally from plastic. A temperature-sensitive switching element (12) is arranged in the region of the winding (9), a side piece (2, 3) of the support member having a box-like cavity (4) which is open on one side. The temperature-sensitive switching element (12) is arranged in this box-like cavity (4) and is thus close to the mounting plate, whose temperature is critical to reliability and whose temperature may not be exceeded when the apparatus is in use. <IMAGE>

Abstract: The process involves coating on both sides of an endless track of a base material consisting of inorganic fibers, preferably a glass fiber fleece, with aqueous ceramic slips, and drying of the coating. The base material with a weight per unit area of 30-200 g/m2 is coated with a slip, at least 500 g/m2, preferably 1000-2000 g/m2, without the use of an additional support, preferably on one side with a paste and on the other side with a glaze slip. The slips contain 3-20% by weight organic binders that decompose uniformly and without residue between 250 DEG  and 600 DEG  C. The dried, unfired veneers in free suspension may be coiled and uncoiled and subjected to continual decoration and firing processes.

Abstract: An optical scanning device comprises an optical system for imaging a part of the surface (10) to be scanned on the detection system (22-25; 122-125). The optical system comprises an objective system (43) and two cylindrical lenses (41, 42) and/or two systems of cylindrical mirrors (141a, 141b, 142a, 142b). In the direction in which the cylindrical lenses (41, 42) have their optical power, the objective system (43) functions as an imaging lens so that a light-intensive and spatial image of the surface is formed at the detection system (22-25). Due to the achieved large numerical aperture, the image formed can also be observed three-dimensionally so that information about the profile of the surface can be obtained by means of the scanning device.

Abstract: Apparatus for determining engine exhaust backpressure in a crankcase scavenged two-stroke engine (10) comprises means (48) for determining a period in the engine cycle during which the inlet and exhaust ports (34,26) of a cylinder (14) of the engine are both open and the pressure in an associated crankcase chamber (18) is substantially equal to engine exhaust backpressure due to airflow between the respective crankcase chamber (18) and exhaust port (26) during said period; a pressure sensor (46) and associated processor (50) for deriving a plurality of values (CCP) indicative of the air pressure in the crankcase chamber during the period, the procesor (50) calculating an average crankcase pressure from the plurality of derived values, and thereby obtaining a value (EBP) indicative of the average backpressure at the exhaust port and determining the amount of air trapped in the cylinder therefrom. An accurate measure of engine exhaust backpressure can thereby be obtained without exposing the pressure sensor (46) to the harsh environment of the engine exhaust.

Abstract: The contact block (1), intended to ensure the passage of a current for therapeutic or aesthetic treatment of the skin of a subject (5) from a cable (2) connected to a suitable generator in an electroconductive cast (6), comprises a plate (3) of elastomer charged with a conducting powder in contact with the core of the cable (2), and an insulating lining (4) cast onto a first face and the edge of the plate (3) lying flush with the second exposed face (3b). The block (1) rests via its lining (4) on a first layer (6a) of the cast (6), which is applied to the skin of the subject (5). A second cast layer (6b) is applied on top of the first layer (6a), in electrical continuity with the latter, and covers the second exposed face (3b) of the plate (3). Thus, the current cannot pass directly through the first layer (6a) of the plate (3) to the underlying skin of the subject (5), which avoids burns due to excessive current density.

Abstract: The slay mechanism for a loom has a shaft (1) which is eccentric relative to the pivot axis (R), for the purpose of affording a partial compensation of mass with respect to the pivoting movement. Slay levers (3), which each have a clamp part, are fastened releasably on the shaft (1). The screw (7), by means of which the clamping effect is generated, is arranged on the same side as the reed, thus making it possible to have a smaller space requirement for the pivoting movement of the slay mechanism than in the state of the art. Components serving as bearing surfaces (9) for intermediate bearings can be fastened to the slay shaft (1) in the same way as the slay levers (3).

On laisse ensuite évaporer le solvant ainsi que les substances liquides ou gazeuses résultant de la réaction chimique. Les valences entrant en ligne de compte pour les réactions chimiques sur la surface du substrat sont saturées après passivation par des radicaux (CH3)3Si.

Abstract: La régulation de la fréquence d'un récepteur miniature s'effectue par un synthétiseur (42) qui est actionné de manière brève pour fournir une tension de syntonisation à un oscillateur local (85) à tension régulée. Un condensateur est shunté à travers la sortie du synthétiseur et il est chargé jusqu'au niveau de la tension de syntonisation. Lorsque le condensateur est chargé, le synthétiseur (42) est désexcité; la tension en diminution fournie à l'oscillateur par le condensateur de décharge est complétée de manière correspondante par une tension de régulation automatique de la fréquence qui trace la déviation du signal reçu dans la bande passante IF. La désexcitation du synthétiseur élimine le bruit du synthétiseur et réduit la consommation en courant du récepteur.
