Title: LF heart beat and biological signals audio generator - uses frequency amplification or input signal squaring to provide signals in audio range
Inventor: BLEICHER WILFRIED DIPL ING
IPC: A61B7/04
Filed: 1979-03-21
Abstract: The process concerns transformation of infra-sonic signals into the hearing range of human ear, i.e. into a range of 20 to 1600 Hz. The heart beat contains frequency components between 10 to 800 Hz. These components cover various heart tones whose frequencies overlap. The detection and differentiations of the 3rd and 4th tones are of particular importance for accurate diagnosis. The transforming system uses a frequency multiplication in order to convert l.f. heart beat and other biological signals into the range perceptible by the human ear. A full wave rectification may be used for this frequency multiplication. Alternately, the squaring of the input signal is used for this purpose.

Title: High melting esp. metal coating hot sprayed onto plastics - using intermediate layer and graded contents of high and low melting metals and plastics
Inventor: HUBER HEINZ
IPC: B05D1/36
Filed: 1980-11-14
Abstract: The Parent Patent describes a composite article or sheet produced by thermal spraying of a surface coating of high-melting substances such as metals and/or metallic oxides, carbides etc. onto a plastics base layer, using an intermediate layer between them to avoid direct effect of the high temperature on the plastics. This intermediate layer is composed of the same plastics material as the backing layer, which can also be thermally sprayed, and of a varying quantity of the same high-melting substance, which is graded in its content either by layers or continuously so that the plastics content decreases from the plastics backing layer through the intermediate layer until there is virtually no plastics content in the intermediate layer immediately adjacent to the high-melting surface metal or similar coating. In the Patent of addn. the intermediate layer also contains a low-melting metal, as follows: starting from the plastics backing layer there is first of all only plastics and low-melting metal further out, the quantity of plastics and low-melting metal decreases and the proportion of high-melting substance equivalent to the surface coating increases.
