Patent DE-2904234-A1 (DE)
Title: IC engine fuel consumption saving - by converting intake oxygen in ozone in HT spark discharge zone
Inventor: FLOERING PAUL
IPC: F02M27/04
Filed: 1979-02-05
Abstract: The air intake (1) of an internal combustion engine (8) is taken, before it passes through a filter (3) into a carburetter (4), through a high-tension spark zone (2) where electrodes, fed by high-tension coils (5), produce spark discharges. These convert some of the oxygen in the air to ozone. The spark discharges are initiated by a revolving distributor (6) which is driven by V-belt from the engine. The current can be supplied by the car battery or by a separate dynamo (7). The result is a better combustion in the engine cylinders, a higher engine output, less toxic constituents in the exhaust gases and a saving in fuel consumption.

Title: Loss-of signal indication in portable transceiver - using threshold detector for monitoring movement of personnel and producing visual or audible indication
Inventor: HOLZER WALTER
IPC: H04B1/3827
Filed: 1979-04-04
Abstract: Portable battery operated miniature transmitter receiver sets are used for maintaining contact with a person whose movements are to be monitored, e.g. a VIP. The set carried by the VIP sends a pulse coded 'wireless' transmission, i.e. by radio, light or ultra-sound. The transmission is received on sets carried by monitoring staff. Each receiver demodulates and decodes the signal and compares it with a preset reference in a threshold detector. If the received signal falls below the threshold, a visual or audible indication is given, showing that the VIP has passed out of range or is shielded by an obstruction. The sets can also be used for two-way speech.

Title: Distortion and contact free determn. of foodstuff fat concn. factor - uses irradiation with soft X=ray or gamma rays and measures inelastic and elastic radiation dispersions
Inventor: KUEHN WILHELM PROF DR
IPC: G01N23/22
Filed: 1979-05-19
Abstract: Determination system is intended for continuous, or intermittent, testing of organic and/or inorganic substances of lower concentration factor number. It is particularly suitable for quality checking of meat and other food products, especially for determination of their fat, oil and/or water contents. The tested substances are irradiated by a soft X-ray, or gamma radiation. Irradiation produces inelastically and elastically dispersed radiation, both these radiation components being separately measured. The ratio of both components is representative for the lower concn factor number. Preferably the tested substances form a multi-component system and the effective concentration factor number is determined by the radiation ratios. The determination may be used both for industrial or medical purposes in a device containing a highly collimated 241-Am-source and a pure Ge detector with an energy resolution of 190 eV at 5.9 keV. The device contains an amplifier and a multi-channel analyser.

Title: Opto-electronic dimension measurement for semiconductor mfr. - using video scanning focal integration, and integral differencing
Inventor: DOEMENS GUENTER DR ING
IPC: G01B11/02
Filed: 1979-09-18
Abstract: The method for measuring microstructure dimensions optoelectronically is esp. for measuring marks and plates used in semiconductor technology. It enables rapid, automatic, objective and efficient measurements to be made under very low contrast conditions with reproducibility of measurements less than 0.1 microns. A video camera is used (e.g. a vidicon or semiconductor image converter) to perform a point-by-point optoelectronic scan in straight lines parallel to the edges being measured. Local intensity is integrated up by lines or line segments. Difference values are formed from the adjacent integral or collective integral values. The measurement value is formed from the extreme values thus measured. This corresponds to a section running perpendicular to the line direction.

Title: Recess printing plate with improved cell quality - produced by etch resist coating, electronic engraving and etching
Inventor: TAGUCHI YUKIO
IPC: B41C1/02
Filed: 1980-09-22
Abstract: A recess-printing plate is produced by (a) forming an etch resist layer of constant thickness on a plate, (b) producing cells, representing the original copy, in the plate by engraving through the etch resist layer using an electronic engraving machine and (c) enlarging the cells by etching. By coating the plate with the etch resist layer before engraving, filling of the cells with etch resist is avoided so that the depth and cross-section of the cells can be increased by etching. The etching step rounds off the shape of the cells so that ink transfer to the surfaces to be printed is facilitated. Thus, reproductions with the correct contrast are obtd.

Patent DE-3100835-A1 (DE)
Title: Drive for a heliostat
Inventor: SCHAEFER HEINRICH
IPC: F24J2/54
Filed: 1981-01-14
Abstract: The invention relates to a drive for a heliostat with two worm mechanisms arranged one above the other with their axes offset, which are installed as a complete drive unit in the self-locking worm wheel sets having adjustable backlash. The worm shaft is axially displaceable and lockable in any position and large shaft diameters in conjunction with short mounting bases serve to increase stiffness. The invention is a further development of patent application P3027962.0 and is characterised in that the self-locking worm wheel sets (9a, b) with adjustable backlash are additionally installed as a final stage in each mechanism and the worm shaft (9a) can be displaced axially and locked relative to the worm shaft (2a) and the shaft with the worm wheel (9b) is rigidly connected to the foundation, and the mechanism (2) with the flanged-on mechanism (1) rotates about the shaft, and large shaft diameters serve to provide stiffness. The heliostat of the invention is used as a drive unit with precise backlash adjustment by simply readjusting the reversal play without disassembling the entire heliostat. Its use is made technically and economically simpler by virtue of this fact and by virtue of the fact that any driving components, such as bevel gear mechanisms, can be used for the worm wheel sets. <IMAGE>
