Title: Stereoscopic colour TV system compatible with existing equipment - uses two luminance and two chrominance signals and third differential luminance and chrominance signals
Inventor: ATHANASE TRAPALIS DIPL ING
IPC: H01J29/32
Filed: 1980-04-29
Abstract: The t.v. signals of the syste- consist of luminance and chrominance signals. For stereoscopic colour t.v. two luminance and two chrominance signals are generated, i.e. one for each observer's eye. The first chrominance and luminance signal is transmitted to the receiver. In addition a third luminance or chrominance signal is transmitted, these signals representing the h.f. difference between the two luminance and chrominance signals. In the receiver the second luminance and chrominance signals are recovered from the first and third luminance and chrominance signals. From the first two derived chrominance and luminance signals are formed signal trains for each observer's eye and applied to the electron guns (red, blue, green) of a colour c.r.t. Through excitation of the phosphor particles of the colour image screen two partial images are generated, each consisting of a half image.

Title: Pasteurising or sterilising foods and pharmaceuticals - by short term contact with very hot air
Inventor: LUDEWIG HEINZ
IPC: A61L2/00
Filed: 1980-09-26
Abstract: Method for pasteurising (Sterilising) granular and powdered foods and pharmaceuticals comprises treating with hot air for a very short time at extremely high temp. Pref. the hot air stream is at 100-200, esp. 150-170 deg.C and the contact time is 1-10, esp. 2-4, sec. The process is carried out in equipment conventionally used for drying moist substances, esp. using air which has been sterile filtered. Opt. the material is sprayed with water to replace water lost during the process. The method achieves almost complete disinfection of cereal flour or other materials contaminated by fungi and bacteria. The very short contact times and the use of a turbulent air stream minimises denaturation of starch and protein, and loss of initial prod. quality. The low moisture content (5-7%) of the treated flour facilitates transport esp. in tropical countries.
