Patent DE-2646385-A1 (DE)
Title: Increasing the protein content of starchy prod. - esp. maize and manioc, by fermentation with yeast having no hydrolytic activity
Inventor: AZOULAY EDGAR ELIE YVES
IPC: A23K1/00
Filed: 1976-10-14
Abstract: The protein content of starch-rich products such as maize kernels or manioc slices is increased fermenting a suspension of the communited prod. (particle size 1 mm) to which has been added mineral salts, an N-source, trace elements and growth factors to give a complete medium. Fermentation is continuous or batchwise using a strain of yeast which causes no chemical or enzymatic hydrolysis of the starch e.g. a strain of Candida tropicalis grown on soluble starch. The fermentation is at pH 4-6 and 30-39 degrees C with vigorous stirring and aeration, then the biomass is centrifuged off, dried and the enriched product is suitable for immediate use. Masize and manioc flour enriched to >=15 wt. % protein prepd. by this method are claimed. The prod. is suitable for human or animal consumption. The yeast used has higher protein content and grows more rapidly than the mycelial fungi previously used.

Title: Hearing aid combined with pair of spectacles - has horns mounted on temples with length chosen according to desired amplification frequency range
Inventor: RENATUS GUSTAV DIPL ING
IPC: H04R25/00
Filed: 1978-05-13
Abstract: Hearing-aid spectacles have horn-shaped tubes (T1, T2) on one or both temples leading to microphones (M). The horn length is related to the desired frequency range. Further variations also use tubes giving a delay effect selective to chosen frequencies and/or directions, thus supplementing the effect of the horns. It is considered that the lowest speech frequencies are not essential for comprehension but that 2000 to 3000 Hz is of special importance. This impairs sound quality but allow conversation with an individual e.g. in a crowded room. The devices may be mounted elsewhere on the wearer, or carried.
