Patent number: 8517905Abstract: A device and a method for accurate dispensing of a radioactive liquid are disclosed. A source of a radioactive liquid and a source of a flushing liquid are selectively connected to a fluid delivery path by way of valve means. An activity metering unit is operable to determine a level of radioactivity in a metering section of the fluid delivery path downstream from the valve means. The device is operated by transporting a first amount of radioactive liquid to the metering section, using the activity metering unit to measure a reference level of radioactivity, calculating a second amount of the radioactive liquid still to be delivered such that the first and second amounts of radioactive liquid together have some predetermined level of radioactivity, and delivering the first and second amounts of radioactive liquid to the destination.Type: GrantFiled: July 14, 2005Date of Patent: August 27, 2013Assignee: University of ZurichInventors: Alfred Buck, Bruno Weber

Publication number: 20090131862Abstract: A device and a method for accurate and remote dispensing of a radioactive liquid are disclosed. A source of a radioactive liquid (1) and a source of a flushing liquid (5) are selectively connected to a fluid delivery path (7, 8, 10) by way of valve means (V1). An activity metering unit (9) is operable to determine a level of radioactivity in a metering section (8) of the fluid delivery path downstream from the valve means (V1). The device is operated by transporting a first amount of radioactive liquid (1) to the metering section (8), using the activity metering unit (9) to measure a reference level of radioactivity, calculating a second amount of the radioactive liquid still to be delivered such that the first and second amounts of radioactive liquid together have some predetermined level of radioactivity, and delivering the first and second amounts of radioactive liquid to the destination (11).Type: ApplicationFiled: July 14, 2005Publication date: May 21, 2009Applicant: UNIVERSITAT ZURICHInventors: Alfred Buck, Bruno Weber

Patent number: 5571298Abstract: To prevent damage to an electrical resistance heater (13-16) which, when energized by electrical energy, for example in the order of 100 A at 12-24 V, a heat reservoir substance is included in the filter, positioned in heat transfer relation to the electrical resistance heater (13-16) and located, with respect to the flow direction of the gas stream through the filter, upstream of the filter material (15). Preferably, the electrical resistance heater is a perforated, tubular sheet-metal structure, axial ends of which are electrically connectable by connecting bolts (21, 25) to an electrical energy supply. The heat reservoir substance (14) is either wrapped at the outside over the tubular resistance heater (13-16), applied as a layer (14a) at the inside of the tubular resistance heater, or filled into the hollow interior thereof in form of a wire wool (14b).Type: GrantFiled: August 9, 1995Date of Patent: November 5, 1996Inventor: Alfred Buck

Patent number: 4940476Abstract: A soot filter for Diesel engines has a housing (2), in which filter material (11) of mineral fibers or yarns is arranged on a support (7). To prevent the filter material from losing its three-dimensional structure necessary for the filtration in the event of yarn breakage, it is formed at least partly or completely of knitted fabric (12), which maintains its internal coherence in the vicinity of individual loops even in the event of yarn breakage because of the interlacing of the yarns in the adjacent loops.Type: GrantFiled: May 17, 1989Date of Patent: July 10, 1990Assignee: Alfred BuckInventor: Alfred Buck

Patent number: 4688401Abstract: A yarn feeding and guide device for knitting machines has at least one yarn feeder, which delivers the yarn arriving from a yarn package and being supplied as needed at a predetermined tension by a yarn delivery unit or fournisseur to the needles of a row of needles. The yarn feeder is disposed in a stationary manner on the machine such that it does not contact the needles of the needle row, and yarn guide elements located in the path of the yarn are associated with it.Type: GrantFiled: June 28, 1984Date of Patent: August 25, 1987Assignee: Memminger GmbHInventors: Falk Kuhn, Alfred Buck

Patent number: 4608841Abstract: In a knitting machine having at least one needle bed, the needle bed is equipped with needles located beside one another, which are guided in a longitudinally displaceable manner under the control of a needle cam race. Combined hold-down and knock-over sinkers that are movable both in the longitudinal direction of the needles and transversely thereto are pivotably supported between the needles, their longitudinal and transverse movement being controlled by sinker cam race surfaces.In order to attain satisfactory, relatively low-friction guidance of the needles and sinkers while operating at high speed, the apparatus is designed such that the needles are disposed on longitudinal ribs disposed spaced apart on the needle bed, and the sinkers are disposed between these ribs.Type: GrantFiled: July 26, 1984Date of Patent: September 2, 1986Assignee: Memminger GmbHInventors: Alfred Buck, Falk Kuhn

Patent number: 4550577Abstract: To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12).Type: GrantFiled: December 8, 1983Date of Patent: November 5, 1985Assignee: Memminger GmbHInventors: Falk Kuhn, Alfred Buck

Patent number: 4546623Abstract: To permit independent adjustment of movement of knock-over bit - jack sinker elements (3) having knock-over or casting-off heads (7), a cam box (22, 23) has an individually adjustable raising and lowering cam track (26, 28), engaging a butt (6) on the sinker element. The shaft (4) of the jack or sinker is formed as a double-arm lever (16, 17) with an intermediate fulcrum or pivot point projection (18), engaging a surface of the knitting machine, for example a cylinder groove, and two individual cam tracks (34, 35) are provided, formed on cam carriers (36, 37), of which, preferably, at least one (36) is adjustable, to provide for rocking movement of the knock-over bit - sinker jack element about the fulcrum or pivot projection independently of sliding longitudinal raising and lowering under control of the customarily provided cam structure (26, 28).Type: GrantFiled: December 8, 1983Date of Patent: October 15, 1985Assignee: Memminger GmbHInventors: Falk Kuhn, Alfred Buck
