Patent DE-2533946-A1 (DE)
Title: Traffic information pilot signal - is used in radio transmission and pilot signals are used to modulate carrier also modulated by transmit gating signal
Inventor: MAETZOLD UWE ING GRAD
IPC: G08G1/09
Filed: 1975-07-30
Abstract: A radio signal recognition system allows anyone of 6 regional characteristic signals to be detected for the purpose of transmitting traffic information. The characteristic signals in the range 20 to 60 Hz provide amplitude modulation of a 57 kHz carrier. The input signal is amplified (1) and demodulated (2) before transmission to a 20-60 Hz bandpass filter. The filter output is converted (4) to a d. c signal amplified (5) to activate a display (6) indicating the presence of an area signal. The carrier is also modulated with a 125 Hz information transmission signal. A band pass filter (7) with a 125 Hz centre frequency is coupled to a phase locked loop (8) and a VCO. Once the 125 Hz signal is detected the traffic information is transmitted through the receiver.

Title: Antimycotic antibiotic mycoheptin prodn. - using selected steptoverticillium mycoheptinucum strain USSR-LIA-1514
Inventor: SCHUKOWA RIMMA ANDREEWNA
Filed: 1975-08-19
Abstract: The process comprises cultivation of the microorganism Streptoverticillum mycoheptinicum on a nutrient medium contg. N- and C-sources and mineral salts, with subsequent sepn. of the mycellium from the culture fluid and isolation of the end-prod. The novel feature is that the strain of microorganism used is Streptoverticillum mycoheptinicum USSR-LiA-1514, which was selected from strain 44 B/1 by inoculation of its spores onto Czapek starch-agar medium contg. mycoheptin Na salt. Mycoheptin is active against the causative organisms of deep and systemic mycoses and against yeast. It is used for the treatment of coccidiosis, histoplasmosis, cryptococcosis, chromomycosis, aspergillosis, sporotrichosis, and candidiasis. Mycoheptin is produced in improved yields, since the new strain of S. mycoheptinicum is 1.5 times more active than the parent strain in producing mycoheptin.

Title: Determining the amt. or detergent required for washing textiles - by using marked vessel and tablets contg. sequestering agents and indicator to measure water hardness
Inventor: ILC VLADO DIPL ING
IPC: D06F33/37
Filed: 1975-09-29
Abstract: Means for measuring out detergent in function of water hardness consists of a combination of (1) a measuring vessel, e.g. a beaker, having vol. 100-300(150-250)ml. and provided with a marking for the quantity of water to be poured in and opt. a graduation for powdered and/or liquid detergent quantity, and (2)>=3 tablets. Each tablet weighs 0.1-3g. and contains, by wt., (a) 1-30% water-soluble sequestering agents forming soluble complex salts with alkaline earth ions; (b) 0.001-0.5(0.01 0.1)% indicator and (c) 69-98.99% standard pelletising agents, disintegrating agents and fillers, which dissolve in water without causing turbidity. Sequestering agent quantity/tablet is measured so that 3-7mg. Ca ions/100 ml. water are completely bonded after dissolving one tablet. Water hardness is determined by filling measuring vessel up to mark with water to be tested. Tablets are then added, with mixing, until a permanent colour change is set up. Each tablet is added after complete dissolution of preceding tablet. Quantity of tablets is directly proportional to water hardness and to detergent quantity to be used.

Title: Gas envelope for moving underwater body - has liq. natural gas stored in Dewar flasks and recovered
Inventor: BELSEN JACOB N
IPC: B63B1/38
Filed: 1976-03-12
Abstract: Natural gas is used for the envelope, stored in liq. form in Dewar flasks. The body tapers towards the tail, the dia. reducing at such a rate that the consequent loss of speed, compared with that of the point of gas emission of the surrounding water due to hydrodynamic causes is the same as that of the gas due to surface friction. To ensure that the body follows a strictly vertical path on release from its airborne carrier provision is made to accelerate it progressively but rapidly immediately before release, to a horizontal velocity equal but opposite to that of the carrier.

Title: Doppler vehicle speed measurement - uses transmission line carrying two phase locked signals and onboard receiver
Inventor: AFFOLTER PETER DR
IPC: G01S11/10
Filed: 1976-04-24
Abstract: One signal is generated at each end of the line, and an on board receiver detects the Doppler induced phase or frequency difference between the two received signals. A transmission line (L) is fed at one end by a crystal oscillator signal generator (S1) with a signal of constant frequency. This is received (E) at the other end of the line and used to generate a second signal at half the received frequency, and this is transmitted (S2) back down the line (L). A vehicle (F) travelling along parallel to the line (L) has an onboard receiver which picks up signals from both transmitted signals but shifted in phase and frequency in both cases by the Doppler shift produced by the vehicle velocity.

Title: Zinc extraction from zinc oxide and/or sulphide ores - by leaching and volatilising leach residue metals for max. recovery
Inventor: WEIGEL HORST DIPL ING
IPC: C22B19/04
Filed: 1976-04-28
Abstract: Zn is extracted from Zn oxide ores and/or roasted ZnS concentrates by leaching and volatilising the leach residues. After neutral leaching, the leach residue contg. a large amt. of undissolved Zn, is dried and contacted in a fluidised state and in a reducing medium, with hot gases. Zn as well as other easily volatilised metal cpds. are evaporated and pptd. as their oxides. The non-volatilised cpds. are recovered as a slag and the mixt. of oxides is subjected to neutral leaching. Ores with high impurity contents may be treated to give high Zn recovery without requiring treatment of the residues to avoid pollution. Cyclone melting furnaces can be used with a consequent reduction in the space occupied.
