Title: Printed circuit layout transfer system - uses flexible slightly yieldable support with etch-resistant layer only soluble in solvent
Inventor: KEPETS PETER
IPC: H05K3/06
Filed: 1979-02-27
Abstract: The board is coated with copper, and is selectively covered by the mask directly prior to etching the exposed surfaces of the Cu. The mask consists of a flexible substrate (3) which is only slightly stretchable, and which is covered by a homogeneous, dense layer (5) of acid resistant material. Layer (5) is insol. in water, but soluble in solvents and removable by pressure. Layer (5) is pref. wax, fat, plastics, or micro-encapsulated lacquer, and pref. contains pigments. Substrate (3) is pref. polyester foil sepd. by a silcone or wax layer (4) from layer (5), so the adhesion of layer (5) to foil (3) is reduced. Layer (5) is pref. covered by a pressure sensitive adhesive, which only functions above a specific pressure and bonds layer (5) to the Cu to form a mask which does not include layers (3,4). The advantage is that only a single masking operation is required, and a ball-point pen can be pressed onto the stack (3-6), so layers (5,6) stick to the Cu.

Title: Impulse radar for measuring wind speeds - receives HF EM waves reflected from inhomogeneities in atmosphere to determine drift velocity
Inventor: ROETTGER JUERGEN DIPL PHYS DR
IPC: G01S13/95
Filed: 1980-07-11
Abstract: The transmitting antenna, emits a series of high frequencies oscillation impules (12), directed vertically above it, which are reflected from the turbulence (14) of the atmosphere. The reflected impulses are collected by two receiving antennae (16,18) and fed to high frequency receivers (20,22). The receiving antennae (16,18) are receptive to different parts of the turbulence (14a,14b) and after a certain period, one part of this turbulence (14a) reaches the position previously occupied by a former part (14b). If the configuration of the turbulence (14) does not change considerably, the receiving antennae (16,18) are receptive to the same turbulence profile only in a time interval which corresponds to the speed of the turbulence from one field of view to the other, this time difference being provided by a correlator (24). The height window (H) in which the displacement speed of the turbulence (14) is measured, is determined by the travel time range of the high frequency impulses. By sampling a number of bordering height fields, a height profile of the drift speed is built up, and can be displayed visually.

Patent DE-3103018-A1 (DE)
Title: Time switch
Inventor: HUSS HANS
IPC: H01H43/12
Filed: 1981-01-30
Abstract: An electromechanical time switch for parked-vehicle heating systems in motor vehicles is proposed, in the case of which a control shaft is caused to rotate by a drive shaft (which surrounds it concentrically) and drives a clock hand, the various switching functions being achieved by axial displacement of the control shaft and hence operation of various contacts. This axial displacement is achieved using a sampling element which is moved along a stationary control cam while the control shaft is rotating. A special switching position provides that a spring latches in a circumferential groove on the control shaft, which decouples the sampling element from the control cam, so that the time switch is blocked after one complete switching process.
