Title: Solar heat collector - made of bonded embossed plastic foils (PT 16.9.80)
Inventor: HOELTER HEINZ ING GRAD
IPC: F24S10/50
Filed: 1979-05-15
Abstract: A solar heat collector consists of two plates of plastic foil which contact each other on the periphery by ribs. The area between the ribs carries projections and recesses of square base area and with a trapezoidal cross-section. The flat tops of the recesses and projections contact each other, like the ribs, and are bonded to each other, leaving clear passages for a heat carrier medium. Pref. plastic material is an ethylene-propylene copolymer, with an admixt. of bitumen to at least one wall. An insulating layer can be added to the side away from the incident radiation. This simplifies the mfr. and assembly of solar heat collectors.

Title: Shaper for interpolator signals in NC systems - uses shaping loop to provide ramped flanks on interpolator pulses
Inventor: SCHLEICHER SIEGFRIED DIPL ING
IPC: G05B19/416
Filed: 1979-05-16
Abstract: The interpolation pulses generated within a numerically controlled machine tool system are shaped to prevent positioning overshoot occuring. A compensating loop operates on both the interpolator command and the error between command and position feedback, to generate a function for the amplification factor, k, k = ko - k1 (Vc = V2) where Vc and V2 are the voltages at the signal pickup points. The compensator output operates on the integrated interpolated pulse in a multiplier to produce a square wave signal with ramped flanks to avoid overshoot occuring.

Patent DE-2941423-A1 (DE)
Inventor: LINDMAYER MANFRED DR ING
IPC: H01H1/023
Filed: 1979-10-12
Abstract: An oxide-free, solderable and weldable coating is applied to the actual contact coating of a contact material of silver/metal oxide. A readily adhering coating is obtained by a copper/silver alloy with 8 - 40% silver being applied to the contact material at a temperature of 779 - 960 DEG C in a protective-gas atmosphere. The method requires no additional operation to remove reaction products. The production costs are kept low due to a relatively low silver content of the coating. <IMAGE>

Title: Reinforced concrete bridge arch construction - involves holding guying anchor points at apex level while lowering halves
Inventor: FERLE STANKO
IPC: E01D21/08
Filed: 1980-04-25
Abstract: Two halves are erected from base points, each upright in its abutment, and then let down to final positions, with guying engaging only the apex, and with swivelling motion about base points in building a bridge arch from esp, reinforced concrete.
