Containers of all sizes can be emptied into the vehicle container which remains sealed against dust loss.
Patent DE-3924129-A1 (DE)
Inventor: KRAUTER IMMANUEL DIPL ING
IPC: F02P3/055
Filed: 1989-07-20
Abstract: A monitoring device for an ignition end stage in an internal combustion engine comprises a make time limiting device for the ignition end stage (5), which is supplied by a supply voltage (UBATT). The make time limiting device is set in operation by a control signal when the make time is determined, and controls the ignition end stage for ignition in the event that ignition does not occur before the limiting time expires. According to the invention, the duration of the limiting time (t = f (UBATT)) can be varied, in function of the supply voltage (UBATT), so that it decreases with increase in the supply voltage (UBATT). This prevents thermal damage or destruction of an ignition end stage due to excessively long make times. In addition, overdimensioning of an ignition end stage is unnecessary.

Title: Correcting attenuation-dependent ultrasonic medical imaging appts. - determining sound damping between reflecting boundary layers and individual transducer in adapting phase
Inventor: HASSLER DIETRICH DIPL ING
IPC: G01S7/52
Filed: 1989-10-23
Abstract: The image display with an ultrasonic imaging appts. involves irradiation of the examination object with inhomogeneous attenuation properties by focussed ultrasonic beams.  The echo signals, reflected from the examination region, are received by an ultrasonic array with a preset active aperture.  In an adaptivee phase, the sound reduction on the sound paths between reflecting boundary layers and each transducer element of the array is determined. From the values of the sound attentuation of the individual transducer elements, correction values are formed for the adaptive phase of the subsequent imaging phase.  Thus the loss at the local resolution in the examination region is considerably compensated, as it was caused by the inhomogeneous attenuation properties. USE/ADVANTAGE - For laparoscopic sonography, with compensation of losses caused by body tissue.

Title: Washing and spin drying system - with external measuring and recycling container, used for drum type washing machine
Inventor: HAUGK JUERGEN
IPC: D06F33/46
Filed: 1989-11-07
Abstract: A domestic washing machine has a drum (1) but no suds container.  It has instead a separate measuring and recycling container (14) in which the washing and rinsing media (17) are mixed with fresh water (16). The washing process begins with a precleaning and measuring phase, when the suds (25) are passed by a pump (13) in the drum (1) and after a certain action time at washing drum speed the suds are pumped back in the container (14). The washing is dewatered at 80-250 rev/min. A pressure sensor (18)  determines the difference in the amount of suds in the container (14). This difference is used to establish the water and washing agent needs for the main wash and for the number of rinsing stages. ADVANTAGE - Minimises the consumption of water,energy and washing agents and produces excellent results in a short time.

Inventor: MASSEN ROBERT PROF DR ING
IPC: D04B35/18
Filed: 1990-05-08
Abstract: For the purpose of the optical control of the quality of needles (10) of a knitting machine, an image sensor camera (20) is used to take a test picture of each needle (10) when the needle is moved out of its rest position in order to form a mesh. The analog image signals read out from the image sensor (26, 30) are converted into digital pixel signals, and the digital pixel signals of the test picture or of individual test zones of the test picture are processed in order to obtain information on the state of each needle. By using a coarse-resolution image sensor (26), coarse defects can be detected at full working speed during normal operation of the knitting machine. Wear phenomena or fine defects in the needles can be determined by using a high-resolution image sensor (30) at special inspection times at a reduced operating speed of the knitting machine. <IMAGE>

Filed: 1990-06-07
Abstract: To print a multi-colour design in succession on textile fabrics, partic. T-shirts, using an assembly with a number of holding points each with a sliding printing screen extending outwards at right angles from a recirculating path, the contours of the pattern are applied or stitched to a reference piece as an original, and the screens are placed over it in succession for alignment in register as its pallet is moved through in successive steps. The printed original is then moved to a register station, and the original pattern is projected on to it to bring the projection and the printed pattern in register. The garments to be printed are then initially passed to the register station, to be aligned, and then moved through the colour stations for the pattern to be printed.
