Title: Conversion of picture patterns into electric signals - uses original which is heated to form thermal image which is taken by pyro-vidicon camera
Inventor: YOSHIDA MASAFUMI
IPC: H04N1/10
Filed: 1977-06-16
Abstract: The picture pattern on the original copy is esp. characters and figures. The picture pattern is converted into electric signals used for copying, transmission or storage. The original copy with characters and figures is heated to form a thermal image corresponding to heat absorption. This image is then photographed by a pyrovidicon camera which delivers corresponding electric signals. An infrared lamp (13') is used. It has a reflector and the infrared radiation passes through a slit (28) onto the original copies (16')which are carried on a conveyor belt (26). The pyro vidicon camera (14) is mounted in a chamber (19) separated from the lamp chamber (18) by a wall (20).

Title: Moulded articles of controllable porosity - obtd. by blending rubber tyre and thermoplastic resin particles
Inventor: TURNER JAMES EDWARD
IPC: C08L19/00
Filed: 1977-07-01
Abstract: A heat and press. moulded prod. comprises a mixt. of particalized rubber tyres, including their fibrous cord content, and a lesser amt. of synthetic resin thermoplastic material bits. The prod. comprises a homogeneously incomplete rest mixt., including portions of a reset mixt. of melted resin and tyre particles and portions of tyre particles alone in a bonded relationship.

Patent DE-2846207-A1 (DE)
Title: Input signal level control for digital receiver - uses closed loop feedback for setting level limit
Inventor: SCHALLER WOLFGANG DIPL ING DR
IPC: H03G3/20
Filed: 1978-10-24
Abstract: The proposed control optimises the level of the input analog signal to a digital receiver having an analog first stage. The control of the input level prevents saturation of the front end components and thus give linear response. One channel of a multichannel digital output is used as the level setting feedback in conjunction with a level reference signal. The normal application is to receivers with multichannel output because here no extra control channel has to be added. The system makes use of fast Fourier transform circuits, and where these do not exist in the receiver they have to be added. No ensor for actual input level is required.
