IPC: H01J17/44
Filed: 1991-04-25
Abstract: The gas-discharge switch for a low-pressure gas discharge contains at least two main electrodes. The distance d between the main electrodes and the pressure p of an operating gas are selected such that the starting voltage reduces as the product p x d increases. According to the invention, a hollow electrode (10) which is connected to a triggering-voltage source (17) is allocated to the discharge path (8). This hollow electrode (10) is connected to the anode (3) via an anode resistor RA. The hollow electrode (10) can preferably also be connected to the cathode (2), via a resistor RK. This design of the starting device results in pre-ionisation within the hollow electrode (10), and corresponding simplification of the starting device. …<IMAGE>…

Abstract: An absorbent disposable sanitary product such as a disposable baby diaper has an absorbent core and a multi-ply body-contacting topsheet. The construction of the diaper reduces raw material consumption and hence reduces at source and, therefore, is environmentally attractive. One of the plies (25) of the topsheet contacts the body but not the core, and another (12) contacts the absorbent core, as well as the body, with a space between the plies (33). The non-core-contacting ply has a plurality of upstanding cuffs (27,28) which improve fecal containment, and the space between the plies reduces wet-back. The thickness of the multi-ply topsheet is less than the thickness of conventional, single ply, topsheets.

Abstract: A bathroom cabinet is known, in which two opposite side mirrors are arranged at an obtuse angle to a front part and are fixed to one part of the cabinet so as to be swivellable by means of a vertical swivel axis. This results in awkward handling for the case of the user wishing to look at himself from the rear using the side mirrors. The object of the invention is to increase the possible functions of the bathroom cabinet and to improve handling of the side mirrors. For this purpose, provision is made for each side mirror (2) to be hinged to the part (3) of the cabinet by means of at least one swivel arm (5) and to be mounted at the upper and lower sides so as to be displaceable in a guide path of the part (3) of the cabinet in the region facing the front part (1). This enables each side mirror to be swivelled on a defined path, a relatively stable position of the side mirror in a swivelled position being achieved due to the forced guiding.

Abstract: A high precision composite amplifier for use in a data acquisition subsystem of a Computerized Tomography (CT) scanner provides enhanced high speed response in terms of reduced settling time. The speed improvement is due to a novel compensation network in which a high frequency pole and a zero in the open loop response characteristic for the composite amplifier are forced to cancel despite component and temperature variations. The resulting amplifier exhibits a simple, higher speed, single pole response. An adjustable circuit is provided for adjusting the placement of the zero to assure optimum pole/zero cancellation.

IPC: A61B17/00

Abstract: A technique for treatment of plaque deposits (120) on the arterial wall (110) of a patient. The technique employs a high pressure jet (126) of sterile saline solution directed at the plaque deposit. The high pressure jet is located at the distal end of a guide wire or catheter (12) which is advanced through the vascular system to the site of the plaque deposit. Optional removal of the debris is via an evacuation lumen within the catheter. 
     This particular technique directs the high pressure jet of fluid distal to the distal tip of the guide wire or catheter. This permits treatment of arteries, which are totally occluded, because the device need not transit the lesion to be effective. Some applications will use the high pressure jet of fluid to open a sufficient passage within the occlusion to permit further dilatation using a balloon (58) integral to or passed over the device. 
     An ultrasonic transducer array located adjacent the high pressure jet permits the attending physician to monitor the procedure. This may be particularly important for those embodiments for which the high pressure jet of fluid may be inadvertently directed toward the vessel wall at short range. The ultrasound device ensures that the jet of fluid is directed at plaque, rather than the native vessel.

Abstract: A method of producing a damp-proofing and/or corrosion-protecting membrane (M) on building structures (1), such as roofs, bridges or pipelines, and where the membrane comprises at least one material layer (2, 4). A layer of cold flow, damp-proofing and/or corrosion-protecting, reaction-setting, bitumen-based adhesive mixture (3) is layed in situ on a first material layer (2) already placed on the building structure (1), optionally merely directly on the building structure, said layer of adhesive mixture being layed in a thickness ( t ) corresponding to 10 to 80% of the total thickness ( d ) of the membrane (M). The latter thickness is in the range of 2 to 16 mm, and the adhesive mixture (3) is of a thick pasty consistency. Before the adhesive layer has set, a second material layer (4) is subsequently layed on the top side of said adhesive layer (3). As a result, the security risks are reduced as well as it is possible to improve the working environment in connection with the production in situ of the membrane, i.e. a reduced release of possible injurious vapours or fumes is provided. In addition, the membrane is very resilient and resistant to formation of cracks.

Abstract: In a machine for centreless cylindrical grinding, the grinding wheel (2) located opposite a control wheel (5) is offset sideways relative to the control wheel and is adjusted radially towards the control wheel (5) by an amount to be ground off on a workpiece (1). The workpiece (1) to be machined is placed on a workpiece support (6) and pressed up against the rotating control wheel (5) by a pressure roller (9) and thereby set in rotation. The rotating workpiece (1) is advanced in the axial direction towards the rotating grinding wheel. The advance is produced either by the control wheel inclined in the vertical direction or by the pressure roller inclined in the vertical direction. During the entire grinding operation, uniform axial and radial forces act on the workpiece (1) virtually independently of the length of the workpiece and of the length and diameter of the concentric tenon to be formed by grinding. The method and apparatus are characterised in that it is possible to grind long concentric tenons of extremely small diameters down to a few hundredths of a millimetre on workpieces having extremely high length/diameter ratio.   <IMAGE>

Abstract: A high pressure, fluid level sensor and seal includes a body supporting a removable end cap and housing a trunnion bearing comprising a pivot disk that is pivotable about a pivot axis formed by a pair of pivot pins that are secured to the base of the end cap. The pivot disk is connected to a control arm that freely passes through the end cap. The pivot disk is also connected to a displacer arm that engages a float or displacer in communication with fluid in a high pressure tank. A compression spring acting between the control arm and the end cap biases the pivot disk against the pivot pins. The control arm engages an operating mechanism in a controller that includes a relay. The body is secured in the wall of a high pressure tank. A high pressure seal is formed by a spacer that forms a slip fit with an annular recess on the pivot disk and which engages the end cap and O-rings. The O-rings couple the spacer to the pivot disk and couple the spacer to the end cap. Small pivotal movement of the pivot disk about the pivot pins does not disrupt the high pressure seal. The entire assembly is readily removable from the tank for servicing without requiring removal of the body.
