Title: Electrostatic air filter for removal of microorganisms
Inventor: EICHMEIER JOSEPH
IPC: B03C3/60
Filed: 1998-05-05
Abstract: The filter is used for the purification of environmental air, and particles are collected on denatured layer. A denatured layer is defined as one that not only contains no nutrients for microorganisms, but is treated with additives to destroy them. The denatured layers are applied to the collector electrode, here the inside of a tube along whose axis the discharge electrode, as wire with virtually radial spikes, is charged > 7000 kV. A tube is chosen as the simplest shape for integration in an air duct. Three layers, strongly acidic, strongly alkaline, placed on either side of a neutral layer, form collector.  The layers are made electrically conducting by the addition of graphite or activated charcoal. Also, layers are impregnated with monoclonal antibodies or substances to counteract endotoxin or to kill fungi. Layer is best composed of individual cells, like a chessboard, with different properties in adjacent cells, so good kill rate is achieved as microorganisms pass across, and through, layers. To keep layers moist, material is impregnated with hygroscopic substance and fine aerosol is dispersed into airstream during operation. Collectors are run in series.

Title: Method for winding a bobbin from a continuous running yarn
Inventor: WESTRICH HERMANN
IPC: B65H67/048
Filed: 1998-10-23
Abstract: The bobbin winding operation, for a running yarn, uses a sensor to register the position of a pressure roller as the winding bobbin diameter increases. The sensor is linked to a control for the spindle drive motor.  When the pressure roller reaches the nominal position zone for a full bobbin, and the sensor transmits no nominal position deviation signals, the spindle drive speed is altered to a slower rate then when winding and also smaller than or equal to the bobbin speed during a diameter increase time, while the pressure roller position is unchanged. The bobbin speed, during the diameter increase, is calculated in advance from values for the diameter increase over time and the bobbin diameter as a function of the bobbin diameter.  The bobbin diameter is measured by the ratio of the rotary speeds of the pressure roller and the bobbin spindle.  The value is registered during the winding cycle with a static bobbin spindle carrier. The reduced speed, when the pressure roller is in the nominal position range, steadily decreases as the bobbin diameter increases.  The speed ratios remain constant, independently of the bobbin diameter, with a faster winding speed than a final speed. After each speed control action, the winding speed is reduced so that the speed ratios remain constant independently of the bobbin diameter. An Independent claims are included for a bobbin winder with a sensor (19) at the pressure roller unit (5), linked to a control (10) for the spindle carrier (11) drive motor (40).  The control (10) has a speed change unit to control the motor (40) speed according to the pressure roller position, between a winding speed and a reduced speed rate. The control (10) is linked to a monitor control unit which registers the rotary speeds of the bobbin spindle and the pressure roller to give the bobbin diameter The carrier for the pressure roller is a rocker (8) mounted to the machine frame at one side.  The sensor (19) registers the angle of the pressure roller carrier (8).
