Title: Radiometric measuring of humidity in granules - using probe calibrated and checked against already calibrated probe
Inventor: GRIESER FRANK
IPC: G01N23/09
Filed: 1972-03-30
Abstract: An appts. for calibrating and checking humidity detectors for granulate, operates by measuring the deceleration of fast neutrons caused by the presence of hydrogen nuclei. Between the granulate and the detector probe, a neutron-absorbing cadmium sheet of various wall thicknesses and/or different depths of penetration is inserted. The cadmium sheet forms a "humidity phantom", enabling an already calibrated probe to be used for the calibration and/or checking of other probes. Since the initial calibration is extremely tedious, involving many hundreds of readings giving a considerable scatter, the results of this work, once it has been done, can be transmitted to any number of probes.

Title: Sheet metal spiral coil for tubular heat exchanger - is produced and installed on continuous cycle processing machine
Inventor: WUERFEL ANTON
IPC: B21C37/26
Filed: 1973-12-05
Abstract: The tubular body of a heat exchanger is rotated and at-advanced through a fixed station where three roller units are placed in a common radial plane. The rollers perform the task of producing a spiral groove on the tube body, bend and locate the spiral fin plate in teh groove and with the third roller set, flatten the groove edges to form a firm location for the fin plates. The first roller set which is used to form the groove consists of three rollers with VEE-shaped radial edges. When they are pressed against the rotating tube, they produce a groove of progressive depth. Since no swarfs are cut, a ridge is formed. This ridge is forced back towards the groove after the fin spiral is located in it. This produces a firm joint between fin plate root and heat exchanger body, thus enhancing the heat flow.

Title: Switching device for pile driving machines - has vertically adjustable pulse generator acting in conjunction with hammer
Inventor: RODE WILHELM
IPC: E02D13/00
Filed: 1974-03-01
Abstract: The switching arrangement is used for pressurised fluid operated ramming machines which have a vertical guide for the ramming hammer and the vertical guide is enclosed by a noise absorbing sleeve. This sleeve prevents direct visual observation of the depth reached by the driven pile. The adjustable height pulse generator is used for providing information about the depth reached by the driven pile. The vertical guide of the pile driver carries a slide with a pressurised fluid actuated driving hammer. The pipeline which carries pressurised fluid has a valve and a manually actuated valve. The control valve is connected by a flexible pipe to the pulse generating valve which is held on the vertical guide. The whole assembly is enclosed by the noise absorbing envelope. The pulse generating valve is adjusted to the required driving depth on the vertical guide and locked into position. When the vertical slide comes into contact with this valve the control valve is actuated and the pressurised fluid supply is interrupted. The driving hammer is lifted into the top position and a new pile inserted.

Title: Epitaxial layer protrusions removal - by etch-resistant coating deposition, heat treatment and etching
Inventor: EMILI WALTER DIPL ING
IPC: H01L21/00
Filed: 1974-07-02
Abstract: Projections produced on the surface of epitaxially grown semiconductor layers on substrates can be removed by first coating the surface with thin etch-resistant layer. The coated substrate is then heated to a temperature near the point of liquefaction to eliminate any pin holes in the coating. Immersion into an etchant dissolves the projections; the final step is the removal of the etch-resistant coating. This is a simpler and less costly method than the coating with an SiO2 layer and a discontinuous etch-resistant film, followed by two etching processes.
