Title: Hydrocarbon conversion processes using mixed phase feed-streams - where heating to reaction temp. is effected in indirect heat exchanger
Inventor: GEWARTOWSKI STEVE ARTHUR
IPC: C10G49/00
Filed: 1980-01-22
Abstract: Hydrocarbon conversion processes are claimed in which a mixed-phase feed stream is heated to reaction temp. and partially vaporised by passage through an indirect heat exchange zone prior to passing to the reaction zone. The reaction effluent is separated into vapour and liquid phases and the liquid phase is heated by passage through a direct-fired heating zone to a temp. >=15-20 degrees F above the temp. of the reaction zone inlet. Thereafter, the heated liquid phase is cooled by passing it through the indirect heat exchanger used in heating the original feed stream. Pref. at least part of the vapour-phase effluent is recycled to the reaction zone as part of the feedstream. The technique is claimed for use in the isomerisation of 7-9C aromatics or 4-7C n-paraffins, in hydroprocessing and in the hydrogenation of olefins, but is also disclosed to be applicable to non-catalytic conversion processes, such as the thermohydrodealkylation of toluene or visbreaking, and other processes, such as the dehydrogenation of 8-18C n-paraffins, etc. The problems associated with the maldistribution of mixed-phase feed stream in fired heaters are reduced.

Patent DE-3028476-A1 (DE)
Title: Monitoring knitter yarn - using laser beam which can register partially damaged yarns
Inventor: LUDWIG CHRISTOPH
IPC: D04B35/16
Filed: 1980-07-26
Abstract: A thin laser beam is directed along the knitting zone of the knitter, to monitor the yarns. The alarm or stop mechanism is triggered by an impulse developed by a signal proportional to the registered intensity of the beam within a given amplitude range in a preset time span. The laser beam is aligned to pass directly in the zone between the knitting surfaces of the sinkers and the eyelets of the leading guide needle row in the extended position. The edges of the knitted fabric are held down. The light beam is received and focused with the intensity established at or directly behind the point of focus. The unfocused laser beams are deflected to a plane vertical to the monitoring laser beam, which is then selectively filtered. The DC component is removed from the signal, proportional to the laser beam intensity, and the AC component forming the pulse is observed through an amplitude and a time window. The alarm/stop action is triggered by a logic AND connection to both windows and a final pulse signal. Designed for knitters and warp knitters, the thin laser beam gives accurate detection of partially damaged yarns.
