Title: TV camera for monitoring late night pharmacy services - is actuated by push-button and is remotely monitored
Inventor: JANSEN WALTER
IPC: G08B13/196
Filed: 1974-11-06
Abstract: Pharmaceutical services are supervised through use of an additional television camera operating in conjunction with the already provided prescriptions box, and emergency information units. The television camera can be actuated by a pulse produced by a push button and then operated without being noticed from outside. On being so operated it may then be monitored by a person in a room remote from the pharmacy. The length of each successive operation may be preset so that the respective television receiver monitor can then revert to normal television reception operation. The system is used for pharmaceutical dispensing after closing hours, and instead of bell contact actuation of the supervising television camera use may be made of a selenium photocell.

Title: Ergosterol and ubiquinone 9 prodn - by hydrolysing a biolipid fraction from the biomass of yeast strains
Inventor: TARASOWA NINA WASILJEWNA
IPC: C12P33/00
Filed: 1974-12-18
Abstract: Simultaneous prodn. of ergosterol (E) and ubiquinone 9 (U9) comprises hydrolysis of the biolipid fraction separated from the biomass of E- and U9-producing yeast strains with alcoholic alkali (pref. methanolic KOH) in the presence of an antioxidant which inhibits the oxidation of E and U9 (pref. pyrogallol); extraction of unsaponifiable components of the hydrolysed mixture (pref. with Et2O); evaporation of the extract until crystals of E are formed; separation of the crystals from the mother liquor; adsorption chromatography of the oil prod. remaining after the removal of the extraction solvent; and pptn. of U9. Ergosterol is used as a starting material in the prodn. of vitamins of the D group (including their metabolites) and of steroid hormones. Ubiquinones (including U9) are active in cardiovascular insufficiency and have a heating effect in alimentary and genetic dystrophy in animals; they also have an effect in human anaemias involving protein metabolism disorders. Simultaneous production of high-purity E (yield 10-15 g/kg biolipid fraction) and U9 (yield 1.2-1.7 g/kg biolipid fraction) may be obtd. from industrial yeasts used in the production of fodder or food protein. Removal of the E- and U9- contg. biolipid fraction from the yeast biomass improves the quality and stability of the protein fraction.

Title: Frequency divider for binary input signal - has repetition frequency specified and pulse width equal to half period
Inventor: KUHN WOLFGANG HANS DIPL ING
IPC: H03K21/10
Filed: 1975-04-21
Abstract: The frequency divider delivers an output signal whose pulse repetition frequency is equal to one n-th part of that of the input signal. It has two counters (Z1, Z2) to which the first input signal (E), and an inverted input signal (E1) are applied. They count from a specified starting number up to the counter capacity. They generate a signal (S1, S2) when the maximum capacity is reached, which resets the other counter to its initial number. A bistable flip-flop (K) is tripped by these signals (S1, S2) to its first or second state respectively. It delivers the divider output signals.
