Patent DE-2407183-A1 (DE)
Title: Electronic digital controller for ignition timing - applicable to reciprocating or wankel engines with external ignition
Inventor: HAPPE KARL
IPC: F02P7/067
Filed: 1974-02-15
Abstract: A toothed wheel driven by the engine, has an outer and inner set of teeth. The inner teeth generate impulses which are transmitted to a number of AND gates to the electronic speed counter. The outer teeth of the wheel generate and transmit impulses to the electronic ignition angle measuring device. The innermost track of the wheel generates a reference signal. The output from the speed counter and angle measuring device are transmitted to the multiplier which has five gates with a common output. The output signal determines the optimum angle of ignition timing to suit the engine speed.

Title: Converting speech frequencies into printed words - involves storing frequencies of individual sounds and then using them to make letters
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/26
Filed: 1974-03-05
Abstract: A frequency generator supplies a given frequency which is applied to a measuring apparatus, lamp or oscillograph and it is used to indicate the presence of an electrical value. A spoken letter comprises several frequencies one of which is a frequency which is similar to the given frequency. When the two frequencies of the spoken word are electrically identical or opposed the apparatus receives a change which is caused by the presence of frequency and serves as the signal for the printed letter. The process may be repeated many times for different letters and phonetic sounds.

Title: Hydrating sodium triphosphate in fluidised bed - for use in washing compsns.
Inventor: LIEDLOFF BERND
IPC: C01B25/41
Filed: 1974-03-16
Abstract: Fluidised bed, heated to 20-80 degrees C consisting of anhydrous triphosphate, is sprayed with water (or Na2SO4 soln) heated to 60-95 degrees C; to avoid caking. Na5P3O10 must have the following granular compsn.: 0.0-0.1% >3.15 mm; 0.0-0.3% 2.5-3.15 mm; 0 0-0.5% 2.0-2.5 mm; 0.5-4.0% 1.25-2.0 mm; 0.4-4.5% 1.0-1 25 mm; 1.0-10% 0.8-1.0 mm; 13.0-51.0% 0.25-0.8 mm; 19 0-53.0% 0.1-0.25 mm; 0.6-15.0% 0.05-0.1 mm. and 0.0-7% 0.05 mm. This granular compsn. prevents excessive evolution of heat and, hence, hydrolysis to the di- or monophosphate. Alternatively, 'inner cooling' can be applied by adding 10-30 wt % of Na2SO4 (opt. hydrated) to the fluidised bed; in this case, the granular compsn. of Na5P3O10 is no longer of importance (Na2SO4 is often used as a component of washing compsns. so that there is no need to subsequently separate the two cpds.).

Title: Semiconductor diode has electric surface field reduced to prevent brea - by suitably dimensioning high-resistivity N-type region below electrode
Inventor: KAUSOW SERGEJ FEDOROWITSCH
IPC: H01L23/485
Filed: 1974-03-18
Abstract: The semiconductor diode consists of an n-type region (1) sandwiched between a p-type region (2) and an electrode (6). The n-type region has a specific resistance greater than 100 times that of the p-type region (and for h.v. diodes, 1000 times greater). The depth (H) of the n-type region is equal to the width of the space-charge region at a voltage below the forward bias voltage. The distance (L) between the edge of the electrode and the edge of the n-type region is not less than twice the depth of the n-type region beneath the electrode. The structure reduces the electric field strength at the surface of the diode w.r.t. the field in the volume of the diode, and avoids surface breakdown.
