Title: Radiography with fast neutrons with the aid of recoil nuclei - uses etching traces of same for image production
Inventor: BAGGE ERICH
IPC: G01T3/00
Filed: 1974-06-14
Abstract: The parent patent describes radiography with the aid of fast neutrons comprising passing a beam of same through a test matl. to be investigated whereby that beam is differentially weakened proportionately to the concn. of hydrogen nuclei present in the test matl. Having passed through the test matl. the fast neutrons are used to split nuclei in a foil of swell-value matl. which then impinge on the actual detector foil. Changes in the foil brought about by the fission prods. are rendered visible by etching. In the addn. the radiation image of a test matl. to be studied is produced by using the etching traces of the recoil nuclei in the plastics detector, which are either released directly in the detector matl. or originate in a layer in front of same. In certain conditions, the swell-value foil may be dispensed with, and images of test matls. with differential hydrogen content may be obtd. with a suitable plastics detector foil alone.

Title: Preparing fly ash of inferior quality for use in concrete - by eliminating coarse fraction
Inventor: SCHOLZ HANS DR ING
IPC: C04B18/08
Filed: 1974-08-21
Abstract: Fly ash to be used as additive for concrete is processed to meet the requirements of the corresp. German Standard (DIN 1045), in particular by eliminating (a) components having a high calcination loss so that the calcination loss of the remaining fly as h is less than 5.0 wt. %; (b) components having a relatively small specific surfaces area so that the specific surface area (according to DIN 1164, Blatt 4) of the remaining ash exceeds 3000 cm2/g; and (e) coarse components so that the size of more than 50 wt. % of the ash particles is =0.04 mm. This is accomplished by eliminating particles larger than 90 mu as a high capacity sieving machine; the elimination of this fraction usually suffices to fulfill all the requirements listed above. The coarse fraction is returned to the furnace because it contains a considerable amt. of coke particles which can be burned. By this method, fly ash of inferior quality can be improved by a simple process and utilised as an additive for concrete.

Title: Separating device for tobacco waste - uses compressed air blast to separate lighter waste on vibrating conveyor
Inventor: WOCHNOWSKI WALDEMAR DIPL PHYS
IPC: A24B1/04
Filed: 1975-01-10
Abstract: The tobacco separating process relies on the waste material being lighter than the product itself. The material to be inspected is fed to a vibrator conveyor. Quantity and weight for the conveyor is controlled by a scale and spread evenly over the width of the conveyor by a rake. The sorting occurs when the conveyor vibrator enters an air shaft with a compressor below. A perforated sheet distributes the air flow evenly before it meets the openings in the conveyor. A throttle near the compressor controls the air pressure. The air flow lifts all material to travel on an air cushion. The light material is sucked up into a funnel and removed. This process may be repeated in a second shaft if necessary.
