Title: Procedure for drying particles of high surface area - by passing stream of heated gas to=and=fro through layer of material for drying without reaching temp. where additives are released
IPC: C02F11/13
Filed: 1990-04-28
Abstract: A procedure for drying granular materials contg. additives consists of placing the particles of the material in a layer (18) on a conveyor (14) which is porous to air and moving them through a drying device (24) inside which a drying gas stream is (26) is passed to and fro through the conveyor (14) and the material (18). It is proposed that the gas stream (26) should be of such a temp. that the max. temp. reached by the material (18) is below the temp. at which the additives in the material (18) would be removed and would pass into the surrounding atmospheric air. The gas stream (26) passes in contraflow to and fro through the conveyora (14). The material (18) pref. remains at all times below a temp. of 348 deg.K. USE/ADVANTAGE - This method is used for drying particles of relatively large surface area of pasty or granular materials which contain solids, water and additives. The materials are dried without removing the additives, which is of advantage in the mfr.  of sausages or noodles when it is required to retain  valuable additives during the drying procedure, and in the drying of contaminated sludges when it is required to prevent dangerous additive elements from being released into the atmos.
Patent DE-4023581-A1 (DE)
IPC: G05B19/406
Filed: 1990-07-25
Abstract: The worktool (7) to be measured is moved into a predetermined measuring position, in which it interrupts a measuring beam (15) of a measuring device. The measuring beam (15) is oriented at an angle alpha  to the x-y coordinate system of the machine tool. A multi-spindle head having a plurality of axially parallel worktools (7) is moved in such a way that the worktools (7) are moved into the fixed measuring beam (15) one after the other. It is thereby possible to sense and measure all the worktools (7) of the most commonly encountered multi-spindle heads (8), using a single measuring beam (15). Even if two worktools (7) are situated in a common horizontal or vertical plane, one behind the other, each worktool (7) is sensed due to the oblique position of the measuring beam (15) to the x-y coordinate system. It is thereby possible to check and monitor the worktools before and after use, for example as regards wear. <IMAGE>
