Title: Electronically controlled suction wheel for sheet feed - uses photodiode and phototransistor for input to delay travel of sheet to conveyor
Inventor: KISTNER HERMANN
IPC: B65H3/00
Filed: 1976-01-10
Abstract: The sheet feed arrangement in which the top sheet (6) on a stack (1) is collected by a suction wheel (5) and advanced towards a belt conveyor (2) for delivery to e.g. a folding machine, has a suction box (7) inside the suction wheel, with its air supply controlled by an electronic circuit. The leading edge of the sheet passes between a photo-diode (13) and a phototransistor (14) connected to the input of the control circuit. These are respectively in series with a further photodiode and phototransistor forming a path controller. The arrangement provides a delay signal, followed by a release signal after a present time, to allow the sheet to travel onwards to the conveyor. The distance travelled is evaluated and the delay signal is generated in a digital form.

Title: Nitric acid pickling of metals - where nitrogen oxide fumes are converted to nitric acid in an enclosed scrubbing system
Inventor: SUBAT GERHARD DIPL CHEM DR
IPC: C23G1/36
Filed: 1976-01-13
Abstract: Metals are pickled with nitric acid or its solns., and the NO and NO2 gases evolved are fed to a scrubbing liq. and converted to HNO3 in the presence of O2. The novelty is that the nitrous gases travel in a closed circuit contg. the scrubbing liq. and also supplied with an adjustable dose of O2 or a gas contg. O2 so that the NOx are removed. The O2 is pref. supplied as air, and the scrubbing liq. is pref. water or dil. HNO3, possibly with the addn. of absorbents or adsorbents for removing NOx. The pref. plant consists of a closed chamber contg. two pickling tanks and two rinsing tanks, and fitted with a fume extn. channel leading to the scrubbing liq. which is also located in the chamber. The chamber also has an air removal duct which causes air to be drawn into the chamber where it is used to aid the conversion of NOx into HNO3. Method is used e.g. for pickling brass or stainless steel. A simple and inexpensive pickling plant is obtd. which avoids environmental pollution.

Title: Sulphur contg. amino acids prodn. - by incubating substd. amino acids with methioninase and sulphur cpds.
Inventor: SODA KENJI
IPC: C12P13/04
Filed: 1976-06-16
Abstract: In prodn. of substd. S-contg. L-amino acids in which the sulphur is bound to the beta or gamma carbon atom of the amino acid, (a) a beta- or gamma-substd. L-amino acid is contacted with an S-contg. cpd. in a methioninase-contg. aq.reaction medium in order to accumulate the substd. S-contg. L-amino acid in the reaction medium; and (b) the substd. S-contg. L-amino acid is recovered from the medium. The beta- or gamma-substd. L-amino acid must be one which is converted into pyruvic acid or alpha-ketobutryric acid when it is held in an aqueous medium with methioninase. The S-contg. cpd. is one which contains an active H-atom and in which at least one free electron pair is assigned to the S-atom. The substd. S-contg. L-amino acid obtd. as prod. is a cpd. in which the original beta- or gamma-substitution is replaced by the entire nucleophilic moiety of the S-contg. cpd. remaining after removal of the active H-atom. Certain of the prods. are physiologically active, while others are used as additives for foods on account on their nutrient effect or their aroma properties. Further prods. are useful as intermediates for therapeutic agents or as experimental or analytical cpds. In an example, various amino acids are incubated with n-propyl mercaptan in a culture of a methioninase- produsing microorganisms. Incubation of L-homocystein with Pseudomonas taetrolens 1FO 3460 gives S-propyl-L-homocystein in a molar yield of 20%.

Title: Providing precise dosage at fluctuating pressures - by keeping pressure differential across metering pump constant
Inventor: GROETECKE KARL HEINRICH DIPL I
IPC: G05D11/03
Filed: 1977-12-03
Abstract: To admix doses of a component B to a high-pressure flow of a component A, an intensifier pump raises the pressure in the mass flow of B to the maximum possible pressure of A. A side stream, diverted upstream of the metering pump, is controlled to equalise the pressure of B upstream of the metering pump with that of A and to keep the pressure drop across this pump to a constant minimum. This ensures constant dosages of the component B over long periods, even when the pressure in the supply line of the component A is high and/or fluctuates.
