Abstract: For assembling and finishing cable sleeves, for example, use is often made of two-component insulating material. Such materials usually fall within the provisions of environmental legislation. The liquid remnants left over after assembly of the cable sleeve are chemical waste and the individual components are harmful, irritant and/or flammable during processing so that these substances have to be dealt with extremely carefully. 
     The invention now offers a system for filling with a mixture of two components a cavity (15) enclosed by a housing, for example a cable sleeve 1, and having a filling opening 8 for placing the mixture in the cavity, characterized by a flexible packaging 19 having three compartments (17, 23, 24) which are mutually separated by two removable dividers (21, 22) and two of which compartments are adjoining and contain the two respective components and the third of which serves as a filling tube (17) for insertion in the access opening (8), which two compartments containing the components can be placed in open communication with one another by removal of the divider, whereafter through kneading of the packaging the two components can form the mixture, whereafter the filling tube can be inserted into the filling opening, the second divider can be removed and the mixture can be carried into the cavity via the filling tube by pressing out the packaging.

Abstract: In an axle suspension device for a vehicle with gas spring suspension (6) and roll stabilisation an essentially rigid stabilizer body (15) is used which is hingedly connected in two points (14, 16) to the axle (2) to be stabilized, each near one end thereof, and in two points (17, 18) to the vehicle frame (1), which latter connections are formed by substantially vertical hydraulic cylinders (31) with piston rods (30), having a sliding bearing (34) in the cylinders, which can absorb transverse forces, the cylinders (31) or piston rods (30) thereof being connected to the frame (1) by rigid connections (35). 
     A control system for such cylinders has a pressure transformer (40) with a larger surface (41), which is directly or indirectly under the pressure of the gas in the gas spring system (6), and has a smaller surface (42), on which the hydraulic pressure in said cylinders (31)acts in the opposite direction, said surfaces (41, 42) being connected for common movement, a control pressure (through 47) exerted by a fluid acting on the other side of said larger surface (41) in the same direction as said hydraulic pressure being variable to control this system depending on one or more parameters on the basis of driving or road conditions. 
     All this allows a simple and reliable design, safety and adaptation of roll stabilizing to different conditions for maximum comfort.

Abstract: A periodontal probe (10) includes sequentially disposed, normally connected sensor (12), shaft (14) and tip portions (16), and a longitudinally extending fiber element (18) in the tip (16) and shaft portions (14). The fiber element (18) is retractable into the tip portion (16) to measure the depths of periodontal pockets in the mouth of a patient, and the sensor portion (12) is operative for generating electrical signals which cumulatively provide indications of the relative positions of the tip portion (16) and the fiber element (18). The shaft portion (14) , the tip portion (16) and the fiber element (18) are preferably disposable and detachably connected to the sensor portion (12) so that they can be discarded after a single periodontal examination. The shaft portion (14) and the tip portion (16) preferably have a combined length of at least approximately 4 1/2 inches so that only the disposable portions of the probe normally come into contact with the hands of a dentist or the mouth of a patient during a periodontal examination. The terminal end portion (66) of the fiber element (18) perferably has a series of different colored annular bands thereon so that a dentist can visually observe the position of the fiber element (18) relative to the gingival margin during a periodontal exmaination.

Title: Methods for activating polymeric carriers and compositions prepared therefrom for use in affinity chromatography.
Inventor: NGO THAT T
IPC: A61K39/00
Filed: 1989-11-27
Abstract: A novel class of compounds, methods for the preparation thereof and the use thereof in chromatographic methods for binding various biologically active materials non-covalently are disclosed. The class of compounds comprises the reaction product of a polymeric gel with a pyridine base, such as 4-dimethylaminopyridine (DMAP), and a halogen-substituted pyridine, such as 3,5-dichloro-2,4,6-trifluoropyridine (DCTFP), which reaction product may in turn be optionally reacted with hydroxyl ions or specified low-molecular-weight compounds. These compounds are capable of selectively and efficiently binding proteins and other organic materials of interest non-covalently to a degree comparable or superior to the heretofore preferred natural affinity ligands, such as Protein A gels. The novel compounds find particular utility in purification and recovery of proteins such as serum albumin and immunoglobulins of various classes from crude sources, such as diluted serum samples from various species.

Title: Device for coating substrates by cathode sputtering.
Inventor: LEYENDECKER TONI
IPC: H01J37/32
Filed: 1990-06-22
Abstract: The invention relates to a device for coating substrates by cathodic sputtering in which the anode is specially designed. The effective anode area is limited by a shutter which is metallically conductive and preferably connected to the inner wall of the chamber and thus is at its potential. The effective anode area is matched to the cathode power so that there is an optimally high ion concentration within the entire chamber. This results in good adhesion of a coating even in those regions which are coated only by means of cathode or substrate movement at a later time.

Abstract: An array [10] of photodetecting active regions [16] includes a layer of photoresponsive material [14] differentiated into a plurality of photodetecting active regions. The layer has a composition which varies across a thickness of the layer from a first surface of the layer to a second surface [14a] of the layer such that a magnitude of an effective energy bandgap of the layer decreases from the first surface to the second surface. A resulting crystal potential field constrains photoexcited minority charge carriers to exist within a region of the layer which is substantially adjacent to the second, narrower energy bandgap surface. The array further includes a plurality of groove structures [18] formed within the second surface of the layer and extending into the layer to a depth less than the thickness of the layer. A groove is interposed between at least two adjacent active regions for substantially preventing minority carriers from laterally diffusing between active regions. The grooves may be combined with ground plane or guard diode structures, each limiting the diffusion of minority charge carriers along a respective axis. The photodetecting active regions may each comprise a reduced area p-n junction.
