Title: Method and apparatus for the separation of a material mixture and use of the apparatus
Inventor: WEBER HEINRICH
IPC: B07B13/00
Filed: 1990-07-26
Abstract: Abstract The invention suggests a new separating method and a corresponding apparatus and the use of the apparatus for the environmentally sound separation of different material mixtures, wherein, in addition to dynamic forces, the area pressure between the bodies to be sorted and an inwardly elastic sorting drum are made use of particularly.     Bodies which are heavy with respect to specific area pressure sink into the interior of the drum and are thrown out at a lower location.  Parts which are light with respect to specific area pressure, on the other hand, are rejected from the surface of the drum and guided away separately.  In so doing, it is possible for the first time using incomparably simple means to achieve a very high separating quality, even with bodies which until now could only be separated economically by hand.  The new invention is particularly effective for the separation of reclaimable material mixtures, so-called "recyclables", particularly with respect to fractions such as liftings which are otherwise difficult to separate.

Patent CA-2035380-A1 (CA)
Title: Abrasive granules
Inventor: BLOECHER ULRICH
IPC: B24D3/00
Filed: 1991-01-31
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an abrasive granule, and, in particular, one which comprises an agglomerate having individual abrasive grains coated on the periphery thereof.  Conventional coated abrasives typically consist of a single layer of abrasive grain adhered to a backing. It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece.  It follows then that about 85% of the grains in the layer are wasted.  To overcome this problem of waste, many attempts have been made to distribute the abrasive grains on the backing in such a manner so that a higher percentage of abrasive grains can be utilized, thus leaving to extended life of the abrasive product.  This invention provides an erodable abrasive granule comprising a plurality of first abrasive grains bonded together by a first binder to form an erodable base agglomerate and at least a partial coating of second abrasive grains bonded to the periphery of the base agglomerate by means of a second binder.  These abrasive granules can be incorporated into a wide variety of abrasive articles such as grinding wheels, coated abrasives, and non-woven abrasives.  The addition of these second abrasive grains dramatically increases the grinding performance over the base agglomerate by itself.

Title: Method of atomizing a liquid and apparatus for implementing the method
Inventor: SCHILLING SIEGFRIED W
IPC: F23D11/30
Filed: 1990-06-27
Abstract: ABSTRACT          Title:    Method of atomizing a liquid and apparatus for implementing the method The atomization or nebulizing of a liquid of a technical degree of purity in a carrier gas becomes difficult, par-ticularly if nozzles are employed, whenever relatively small mass streams (< 2 kg/h) are to be atomized at a high degree of fineness (<< 100 µm); that is, the smallest liquid droplets must be produced at low throughputs.    If one charges the liquid to be atomized onto an open-pored contact body and drives it through the pore channels by means of a gas, small, constantly bursting bubbles form on the surface of the contact body.  This produces ultrasmall droplets which are carried away by the carrier gas.  For liquid mixtures including fractions that have different boiling points, heating of the contact body causes the low boiling point fraction to be evaporated, with the vapor together with the still liquid fraction producing the bursting bubbles at the surface of the contact body.     With the aid of this method it is possible to ultra-finely atomize with comparatively low energy consumption even small mass streams.

Filed: 1991-03-05
Abstract: A method for creating a registered pattern on a metal coil includes providing a pattern applicator roll and a drive motor for rotating the roll, moving the coil into contact with the applicator roll to permit it to create a pattern sequentially on the moving strip from the coil, measuring the pattern length and comparing the same with the desired pattern length, and adjusting the speed of rotation of the pattern applicator roll if the measured pattern length departs from the desired pattern length by a predetermined amount.  Preferably, coil line speed is also monitored.  A microprocessor may be used to effect the comparison between the desired pattern length and the actual pattern length.      Apparatus for creating a registered pattern on a metal coil includes a pattern applicator roll which has the strip from the coil moved into contacting relationship therewith, an appropriate drive motor to drive the roll, and apparatus for monitoring coil line speed, pattern length and motor speed.  A microprocessor stores the desired pattern length and receives information regarding line speed, pattern length, and motor speed, and where an adjustment is desired, either speeds up the applicator roll where the pattern length is longer than the desired pattern length, or reduces the applicator roll speed, if the pattern length is less than the desired pattern length.
