Title: Support vehicle for artillery gun weapon
Inventor: BECKER WILFRIED DIPL ING
IPC: F41A23/34
Filed: 1997-03-27
Abstract: The vehicle has a sprung movement mechanism (3) and at least one support device (5) arranged in a battle position between the vehicle (1) and the ground (4). The support device incorporates at least one support (6) which transfers to the ground at least a part of the recoil forces acting on the vehicle during firing and this via a floor-side foot part (10). The support of the support device is displaceably arranged by means of a positioning motor (15) in the direction of its longitudinal axis (7).

Inventor: KRUMBIEGEL PETER PROF DR
IPC: G01N33/497
Filed: 1997-12-03
Abstract: The invention relates to a device which can be used in conjunction with a conventional analysis system for diagnosing the metabolic capacity of the respiratory tracts. The device enables specific quantities of suitable diagnostic agents to be added to the inspired air and after a certain time span, can be used to collect metabolites of the diagnostic agents present in the expired air and/or the diagnostic agent itself if still present. Conventional analysis systems are then used to identify the substances which have been expired and collected and determine the quantities present (e.g. using mass spectrometry, gas chromatography, GC-MS-MS, HPL-MS, isotope analysis). Conclusions can then be drawn as to the state of health of the respiratory tract organs. The invention also relates to diagnostic agents which can be used for determining the metabolic capacity of the respiratory tract epithelium, and which are used especially advantageously in conjunction with the inventive device, and to an analytical chemical method for determining the metabolic capacity of the bronchial epithelium.
