Patent DE-2344248-A1 (DE)
Title: Laminating resin-impregnated webs or films onto wooden panels - using metal fibre fleece as pressure pad (or pressure equalising plate)
Inventor: SCHAEFER WERNER
IPC: B27N3/20
Filed: 1973-09-01
Abstract: The webs or films are laminated onto wooden panels using a metal fibre fleece as pressure pad (or pressure equalising plate). In the parent patent, a compressible metal fibre fleece was used which resumed its original thickness when pressure was removed. The fleece now comprises several layers where the predominant fibre orientation of each or some layers subtend an angle to one another. This gives longer service life of the pad, even mass distribution and improved mech. strength. The fleece may be surrounded by a thin-mesh metal or glass-fibre nety which may be needed to the fleece. The pref. angle mutually subtended by the fibres is 90 degrees.

Title: Machine tool numerical control connection - embodies adaption and time controlled interpolator determining coordinate feeds
Inventor: MEYER JUERGEN DR ING
IPC: G05B19/416
Filed: 1973-09-13
Abstract: Connection arrangement for a numerical machine tool control, partic. of the lathe type, in which a time-controlled interpolator determines the co-ordinate fees in the controlled axes, the calculating time of which forms a time generator dependent upon an adaption incorporation in the connection arrangement. The frequency of the calculation time is limited by means of a dimension proportional to the speed of the spindle or the rotating tool. A limiter connected between the adaption and the time generator derives its limiting voltage from a tachogenerator which is coupled to the rotating spindle, the drive motor or the rotating tool. The output voltage of the tacho-generator is conducted over switchable resistors whose values are staged in relation to the gear transmissions. The time generator incorporates a digital calculation time adjuster, whereby the frequency of the calculation time is limited by the frequency of an impulse transmitter connected to the spindle and rotating tool.

Title: Circuit producing signal according to relative amplitude difference - to distinguish between two signals in two different channels
Inventor: FIXLER JON SCOTT
IPC: H04Q1/44
Filed: 1973-12-17
Abstract: An inverter inverts one of two input signals and a switching matrix combines algebraically the inverted signal with the other of the two input signals in order to produce a third signal. A gate responds to a predetermined polarity relation between the third signal and the first of the two signals in order to produce an output signal. The second of the two signals can be inverted and a third signal is formed as an algebraic sum of first signal and second inverted signal multiplied by a predetermined value. The gate can have a first and second input and an output, the third signal being led to the first input and the second signal to the second input.

Title: Complete or partial hydro-therapy device - has stacked sections each with controllable fluid jets
Inventor: WICHMANN HANS A DIPL ING
IPC: A61H9/00
Filed: 1974-07-04
Abstract: A device for hydrotherapy in which bodies or body sections, partic. extremities are subjected to bombardment by a large number of aimed water jets, is constructed such that closed component parts with apertures allowing outflow of water in certain directions only are built up to give coverage of the areas to be treated.

Title: Travelling wave detector for HF light demodulation - barrier layer capacitance creates no lateral limits
Inventor: MUELLER R PROF DR
IPC: G02F2/00
Filed: 1974-09-04
Abstract: The light is incident on an optical waveguide of low absorption in which charge carriers are produced by absorption as a result of the light wave generated in the wave guide. The resulting currents excite an electromagnetic wave which travels with the light wave. The waveguide is pref. intrinsically conducting. The electromagnetic wave travels between conducting plates (M) in synchronism with the light wave so that the demodulated electrical signal corresponds exactly to the light modulation independently of the distance travelled by the light in the detector.
