Title: Appliance for sanitising large-volume furniture articles and items of clothing stored on racks for ready-made clothing, which are contaminated with chemical substances and emit these
Inventor: GERISCH ROLF
IPC: F24F8/26
Filed: 1993-02-17
Abstract: The pollution of the air in rooms by chemical substances is often caused by individual emittants such as writing desks, chairs upholstered in leather, couches and pieces of furniture. In clothes department stores, hundreds of men's suits and ladies' dresses are stored on clothes racks. These materials emit numerous chemical substances which were used during the dyeing and finishing of the materials. Persons who are exposed in rooms containing such items of furniture or who wear clothing thus contaminated must be prepared for possible deleterious effects on their health and wellbeing, especially if they are allergic. The invention relates to a device for disposing of such organic substances. The pieces of materials to be sanitised are introduced into a flexible tent-like construction. The closed tent is injected with prefiltered air, predried over silica gel (humidity +/-1%), and heated to 100-110 DEG C. In the process, the inflowing air passes an ozone zone generated by means of 2 Hg high-pressure vapour lamps. The chemical pollutant molecules of varying resistance thus liberated are destroyed or eliminated by the action of the heat and/or by the ozone. At the opposite side of the air inlet there is situated a multi-stage absorption unit with an upstream fan and microfilter.

Title: Method for calibration of randomly elliptical, orthonormal (orthogonal) polarization bases
Inventor: ZIEGLER VOLKER DIPL ING
IPC: G01S7/02
Filed: 1993-09-15
Abstract: In the case of a method for calibration of randomly elliptical, orthonormal polarization bases, power is taken from a received radar transmission pulse and the pulse is sent back to the transmitting radar, with a delay. Three measurements are subsequently carried out at different rotation angles to the horizontal of a linear-polarized channel-horn antenna (groove-horn antenna) of the radar calibration equipment, the first rotation angle ( PSI I) being determined by the orientation angle ( phi ) of the major half axis of the first base vector of the orthogonal base to be calibrated, the second rotation angle ( PSI II) being determined by the orientation angle ( phi ) of the major half axis of the second base vector of the orthogonal base to be calibrated, and the third rotation angle ( PSI III) being determined by half the difference between the first and second rotation angles. Finally, the relative system transfer characteristics are determined with the aid of three scatter matrices, which can be evaluated by the three rotation angle configurations, of the radar calibration equipment, with the criteria which are to be implemented being converted, in that defined, relative matrix elements are evaluated.

Title: Device for the ordered clearing of cross-wound bobbins from a conveyor band running along a machine producing cross-wound bobbins
Inventor: REISING REINER
IPC: B65H67/06
Filed: 1993-10-20
Abstract: The object of the invention was to propose a device of this type which has a simpler design and higher reliability in relation to the state of the art. According to the invention, the conveyor band is assigned means which monitor its position in the direction of transport. An information memory stores the depositing of the cross-wound bobbins on the conveyor band by a change device, with the depositing point being assigned. The means for monitoring the position of the conveyor band and the information memory are connected to a comparator device which compares the correspondence between the depositing point and the position of the conveyor band in the region of the point where the cross-wound bobbins are taken off from the conveyor band. A sorted take-off of cross-wound bobbins from the conveyor band is guaranteed in this way, even when cross-wound bobbins of different batches are deposited on this conveyor band. Moreover, incorrect occupancies of the band, which can occur, for example, after the extraction of cross-wound bobbins by hand, can be detected. <IMAGE>
