Filed: 1990-02-03
Abstract: Autoclave for vacuum steaming of yarn package has an independently driven conveyor for loading, unloading, and processing, and has automatic control of steam vacuum, with screen protection of packages to avoid saturation, or drying. The yarn package (23) preferably has a perforated centre core for steam entry, and to sit on a stub spindle on the conveyor band (6), which is driven by a controlled motor around the wheels (7,8). The passage of a cone (23) across the sensor (29) commences the action of the machine. The cone is guided on to the conveyor by a funnel shape passage (24) and a further sensor (30) checks the loading. Steam enters the system at each side by piping from a condenser and entry valve (2). The steam circulates in an outer chamber (5) which has insulation on the outside (12), and a perforated (4) screen (3) inside. This prevents the cones from receiving excessive treatment by the steam, and additionally there are buffer screens in the initial sector (10), which has flexible doors to allow entry of the cone, mounted on the conveyor. ADVANTAGE - The manual loading and unloading, with heavy consumption of time and energy is avoided. The control system avoids condensate in the package, and a cooling  chamber enables the yarn to be taken direct to winders.

Title: Raising power and using drive forces acting on one side - alternately changing EM fields in time produced by mechanically coupled field generators
Inventor: FRISIUS OLIVER
IPC: H02N11/00
Filed: 1990-04-18
Abstract: Electromagnetic fields are produced by at least two field generators firmly coupled mechanically and or applied so that the field produced by them can be produced as often as required by h.f. switching on and off of a control current.
