Patent number: 6129894Abstract: A device is provided for taking swab samples and sample dilution. The device has a plug made of a porous, absorbent material, which projects from a sleeve and is used to take a swab sample. The plug is located in one end of the sleeve. A piston, which can be moved in the sleeve by means of a piston rod, is located in the other end of the sleeve. A closure, which can be opened by means of pressure, is located between the piston and the plug, so that a liquid arranged between the piston and the plug moves through the closure to the plug and wets same on actuation of the piston rod.Type: GrantFiled: April 30, 1999Date of Patent: October 10, 2000Assignee: Drager Sicherheitstechnik GmbHInventors: Horst Rabenecker, Rainer Polzius, Gero Vornbaumen, Andreas Manns, Thomas Wuske

Patent number: 5312593Abstract: A detecting device in the form of a testing tube or dosimeter having a carrier indicating a color reaction requires a reagent liquid for carrying out a measurement. The reagent liquid is contained in a separate reagent supply vessel and the carrier is impregnated with a color indicator. For carrying out a measurement, the reagent supply from the supply vessel must be brought into contact with the porous carrier. A uniform wetting of the surface of the carrier subjected to the reagent solution is achieved after the reagent solution is emptied from the supply vessel. This is achieved by providing a reagent collection chamber between the carrier and the reagent supply vessel into which the reagent solution pours when the supply vessel is opened and wherein the reagent solution is accommodated and into which the carrier extends so that its end face is subjected to the reagent solution so that this end face can be wetted at the same time.Type: GrantFiled: June 1, 1993Date of Patent: May 17, 1994Assignee: Dragerwerk AktiengesellschaftInventors: Horst Rabenecker, Klaus-Peter Rindt, Stephan Scholtissek, Wolfgang Breithaupt

Patent number: 5139746Abstract: The present invention pertains to a multiple holder for test tubes, which receives a plurality of individual test tubes for the simultaneous flow-through of a gas sample with the gas entering the tubes through at least one opened end, from a connection piece which has a flow outlet. The multiple holder of the invention receives commercially available test tubes with fused tips and includes an arrangement to simultaneously open all the test tubes introduced. To achieve this, the multiple holder 1 is designed such that at least one section 6, 6a can be tilted down, as a result of which the tips 8 of all the test tubes 2 introduced can be broken off simultaneously at least at one end.Type: GrantFiled: December 11, 1989Date of Patent: August 18, 1992Assignee: Dragerwerk AktiengesellschaftInventor: Horst Rabenecker

Patent number: 4896649Abstract: A method and device for the opening of breakable ampules, especially glass test tubes, includes a scoring tool for scratching the end which can be removed by a break-off device. A clean scratching of the ampule end can be executed, producing a smooth fracture by applying an ever constant force exerted on the ampule ends, in order to avoid lengthwise scratches in the body of the ampule from internal stresses. For this, an ampule receiver is provided, into which the ampule can be introduced as far as a stop. It is then rotated while lodged herein with the end of the ampule against the scoring tool. The scratched end of the ampule can be broken off when the ampule is advanced beyond a breaking step.Type: GrantFiled: June 30, 1988Date of Patent: January 30, 1990Assignee: Dragerwerk AktiengesellscaftInventor: Horst Rabenecker

Patent number: 4856818Abstract: A folded record medium for two to four different, segmentally arranged information portions is configured so that the interrelated segments of the information portions are easily accessible in a meaningful arrangement. According to the invention, this is achieved by the fact that the record medium comprises square sheets, which are joined together along a first fold line, and the connected pairs of sheets are joined together, stairway fashion in the unfolded state, along a second fold line, perpendicular to the first fold line and having the length of one side of a sheet.Type: GrantFiled: March 25, 1988Date of Patent: August 15, 1989Assignee: Draegerwerk, AGInventors: Horst Rabenecker, Jurgen Kruger

Patent number: 4528160Abstract: A housing contains a diffusion indicator tube provided with a predetermined breaking point and the housing has an upper part and a lower part joined together by a film hinge. To open the inserted diffusion indicator tube its predetermined breaking point is positioned opposite the film hinge. By bending the housing parts, the break-off end breaks off the test tube at the predetermined breaking point, thereby opening the reaction section. The parts of the test tube are removed, and then the reaction section is pushed into the upper part, now with its closed end first, whereupon it is snapped into the lower part. Its opening at the bottom shoulder of the lower part is exposed to the ambient atmosphere which diffuses into it. In the presence of the gas to be monitored there will be discoloration due to reaction. The discoloration can be observed continuously through the open side of the holding means.Type: GrantFiled: May 31, 1984Date of Patent: July 9, 1985Assignee: Dragerwerk AktiengesellschaftInventors: Wolfgang Eckstein, Kurt Leichnitz, Karl-Heinz Pannwitz, Horst Rabenecker, Gunter Wolff

Patent number: 4298010Abstract: A breathing alcohol testing device comprises a tube for blowing expiration air therethrough which has a first air entrance end and an opposite second end with means for accommodating a testing tube containing a gas detection substance. A pump is connected to the tube for moving expiration air through the tube and pressure sensing means are associated with the tube for sensing the pressure adjacent the entrance end for regulating the pump in accordance with the sensed pressure. In addition to the sensing of pressure, velocity may also be sensed and a control device is connected between the sensors and the pump so as to regulate the pump to start after the tube is engaged in a person's mouth and he begins expiring his breath into the tube and a certain pressure is generated at a certain velocity. The pump may be provided directly in the line ahead of the gas testing device for forcing the breathing air through the tube and through the testing device or it may be provided downstream of the testing device.Type: GrantFiled: October 30, 1979Date of Patent: November 3, 1981Assignee: Dragerwerk AktiengesellschaftInventors: Wolfgang Eckstein, Horst Rabenecker
