Title: Continuous drying process - decrease in flow velocity increases product thickness during desorption drying
Inventor: KESSLER HEINZ-GERHARD DR ING
IPC: F26B3/00
Filed: 1971-12-21
Abstract: In a method for the continuous drying of granular product, initially dried by evaporation of the adhesive bound water, the product is moved over or along heated platens, followed by a desorption drying stage in which the sorptive bound water is removed, the product being moved over special heated platens and with a greater product thickness than that of the earlier stage. The increase in product thickness is obtained by decreasing the average product flow velocity and/or a step-back flow method. The special desorption drying platens are of hollow construction with perforations to allow the circulation of a gas. This method increases the plant capacity and reduces plant size.

Title: Drive for borehole making plug - has flexible hoses to hydraulic power source for actuating reciprocating mass within plug
Inventor: HAENCHEN SIEGFRIED
IPC: E21B4/14
Filed: 1973-08-10
Abstract: The tapered plug used for driving boreholes into the ground is operated hydraulically. The reciprocating mass within the borehole making plug can be changed over to produce impacts for forward driving and for reverse direction driving. The reciprocating mass is a hollow body with polygonal outside profile. The tubular reciprocating mass houses a concentric piston and this piston has channels which are connected to the flexible hydraulic hoses. These channels have radial openings and the piston arrangement has guide rings and seals.

Title: Simple two channel multiplexing system - is used to modulate two sound frequency signals onto single channel
Inventor: DAVIDSON JOHN R
IPC: H04S3/00
Filed: 1974-06-14
Abstract: A coder comprised of a local oscillator and a diode matrix is inserted at the transmitter.
