Title: Guide catheter in the form of a flexible or rigid tube
IPC: A61M25/08
Filed: 1988-08-27
Granted: 1992-05-13
Abstract: A guide catheter (1) in the form of a flexible or rigid tube receives and guides a balloon catheter in order to expand the coronary arteries (9) of the heart. The catheter wall in the region of the catheter tip (5) recedes from the edge over part of the periphery (6). When the tip of the guide catheter is inserted for only a short distance through the opening (8) of a coronary artery, blood from the aorta can pass through the wide flow cross-section into the catheter and into the coronary artery. This ensures a supply of blood to the coronary artery. When the guide catheter is pushed further forward, the recess is closed off by the wall of the opening of the coronary artery, so that injected contrast agent enters the coronary artery but not the aorta.

Title: Gas supply fitting
IPC: F16K17/38
Filed: 1989-09-07
Granted: 1993-02-24
Abstract: The invention relates to a gas supply fitting for gas tubing having a plug for safeguarding a gas pipe in the event of fire, having a housing, in which a valve body preloaded against a spring is arranged. Gas supply fittings are standardised in DIN 3383. It is true that the gas supply fitting is provided with a valve mechanism which closes upon withdrawal of the plug fastened to the gas tubing, but if the gas tubing is damaged in the event of fire, gas can blow out freely. In order to create a simply constructed gas supply fitting with thermal release of a valve body, and keep its release time very short, it is proposed that a valve body has a retaining pin with an annular groove, that a blocking pin engaging in the annular groove is inserted in a longitudinally displaceable fashion into a housing bore extending transversely to the axis of the retaining pin and is, on the one hand, supported via a compression spring in the joint housing, and that, on the other hand, the blocking pin is acted upon by an axially moveable pin of an elastic cartridge, in order to displace the blocking pin, until a circumferential groove of the blocking pin releases the annular groove of the retaining pin. <IMAGE>

Granted: 1995-02-22
Abstract: At a first frequency (30), flux transitions are achieved which result in large excursions of the information signal. The first frequency approximates the maximum frequency at which such excursions can occur. A second higher frequency (89) is utilized to create small or no excursions. At this second frequency, a complete flux transition is not achieved. Information is represented by the presence or absence of excursions. An adaptive, self-compensating scheme, which is self-adjusting in real time and provides for recovery of the nominal flux transition independent of the information pattern, is utilized. Data recovery is qualified through the use of an excursion detection scheme which compares variations in the tracking peak (91) detect value with the input signal separated by an excursion threshold value. When the input waveform falls below the adaptive threshold voltage (94), a data transition is defined.

Abstract: 1. Safety valve which is replaceable under internal tank pressure. 2.1 Safety valves protect tanks and pipelines against unacceptably high overpressure. The function of the safety valves must be tested at specific time intervals. If a safety valve which is replaceable under internal tank pressure is screwed out in conjunction with a closing valve, the tank has no safety valve during this replacement phase, that is to say it has no overpressure protection. 2.2 If the valve closing cone 6 is provided with an acoustic warning and signalling device 3 on the side facing away from the flow, that is to say on the pressure tank side, this device is triggered as soon as the safety valve is screwed out and thus provides a penetrating and continuous warning to reinsert a new safety valve. 2.3 Especially for liquid gas tanks with a propane-butane filling, this device is suitable for recurrent testing of the safety valve, without having to empty the pressure tank. <IMAGE>

Abstract: A process for fabricating field effect transistors with lightly doped drain (LDD) regions having a selected width includes a method of optically detecting the width of spacers used to mask the LDD regions during the source and drain implant and a method of electrically determining (confirming) the width of the LDD regions. In the optical method, reference structures are formed concurrently with the fabrication of the gates for FETs, a spacer material is formed on the substrate, the gates and the reference structures, the spacer material is etched away and the width of the spacers is optically detected by aligning the edges of spacers extending from two reference structures separated by a known distance. In the electrical method, the width is determined by defining a test area with known dimension, forming both N<+> and N<-> regions in the test area, measuring the resistance across the test area, calculating the resistance of the N<+> and N<-> regions, and calculating the width of the N<->region from the resistance of the N<-> region.

Abstract: Les alliages d'aluminium et de lithium artificiellement vieillis reçoivent un traitement thermique auxiliaire à la fin du vieillissement, ou après celui-ci, afin d'améliorer les caractéristiques de leur section transversale courte, et notamment leur ténacité à la rupture. Le traitement thermique auxiliaire consiste à chauffer le matériau de façon régulière jusqu'à une température d'inversion supérieure à la température de vieillissement d'au moins 20 °C mais ne dépassant pas 250 °C, à maintenir le matériau à cette température pendant une courte période, puis à le refroidir jusqu'à la température ambiante. Normalement, le traitement consiste à chauffer le matériau jusqu'à une température d'inversion comprise entre 190 et 230 °C et à le maintenir à cette température pendant environ 5 minutes. Les caractéristiques intensifiées se dégradent lors de l'exposition prolongée aux températures égales ou supérieures à 60 °C, mais peuvent être restituées par une répétition du traitement thermique auxiliaire.
