Title: Blood pressure measuring system - has flow sensitive converter in passage between two chambers in sleeve and electronic processing system
Inventor: NEUSEL ROLF
IPC: G01H11/06
Filed: 1978-03-03
Abstract: The blood pressure measuring system preferably uses a two-chamber sleeve. In a connecting passage with low flow resistance between the two chambers is a flow-sensitive converter, whose upper frequency limit allows conversion of flow modulation in the Korotkoff Tone frequency range. The converter output signal has electronically selected from it according to amplitude, phase, frequency, relative time, and absolute time duration those portions caused by the patient and attributable to heartbeats, opening and closing of arteries, and alteration of the volume of the part of the body below the sleeve on occurrence of the Korotkoff Tones. These signal portions are selected and compared for sorting into true blood pressure signals and unusable ones, which are re-processed to stop signal emission and emit a fault signal. Electronic equipment selects typical fault surge signals occuring for pulse duration, amplitude and group number and emits a gating signal.

Title: Burner for TIG, MIG, or MAG welding - where protective gas nozzle with special profile and/or stream of air is used to reduce formation of toxic ozone
Inventor: FLORIAN WOLFGANG DR RER NAT
IPC: B23K9/29
Filed: 1978-12-19
Abstract: The formation of ozone is avoided or minimised by either (a) employing a protective gas nozzle with a specific profile on the burner, or (b) blowing air or another gas into the stream of protective gas so the latter forms a vortex. The protective gas nozzle is pref. a separate accessory used on the burner, and partial or complete screening of the ultraviolet radiation in the arc is pref. employed to reduce or suppress the formation of ozone created by the ultraviolet radiation. Arc welding produces noxious gases such as O3, and NOx, but the O3 is most harmful to human health and must therefore be removed.
