Title: Monitoring instrument for mark-space ratio of pulse generator - transistor and voltage divider generates negative or positive voltage
Inventor: HERTEL HANS-JOACHIM ING GRAD
IPC: G05B23/02
Filed: 1974-12-28
Abstract: A simple instrumentation package enables a continuous check to be made of the mark/space ratio of the output signal from a pulse generator of the type used in industrial sequential control systems. The pulse generator (1) is coupled to a supply source (2) and the output is connected over voltage dividing resistors (8) to the base of a transistor (7). A voltmeter is coupled between the transistor and the junction of a voltage divider (4, 6). When a pulse is generated the transistor impedance is low and a current flows over resistor (4). When the pulse goes low the impedance is high and current flows over the resistor (5). With the pulse generator operating continuously the voltmeter adopts the zero condition.

Title: Cast iron inoculation - during pouring operation from tiltable inoculant container with oxygen blast nozzle
Inventor: CASPERS KARL-HEINZ
IPC: C21C1/00
Filed: 1975-12-05
Abstract: Molten cast iron is inoculated with an additive which is added at a uniform rate to the iron as it flows from a taphole or spout during a pouring operation. Oxygen is blown against the pouring irong during, and also before and after, the inoculating process. This results in favourable conditions for the formation of extraneous seed crystals and for the pptn. of oxide particles in the jet and in the ladle. The oxygen blast intensifies this effect. The container for the inoculating agent is equipped with an oxygen spray nozzle. The inoculant is pref. added to the pouring iron at 200mm. from the ladle spout.

Title: Acylase enzyme immobilisation - on lamellar aluminium hydrosilicates modified with amino-silanes
Inventor: HUELSMANN HANS-LEO DR
IPC: C12P41/00
Filed: 1976-05-04
Abstract: In a new process for immobilizing acylases to silicaceous carrier masses by linking via cpds. contg. amino gps. as the silicaceous carrier mass there are used Al hydrosilicates having a lamellar lattic structure which are modified with silanes contg. amino gps. Immobilized N-acyl-L-amino acid amidohydrolases (amino-acylases) are useful for optical resolution procedures involving selective deacylation of the L-isomer of a racemic N-acyl-aminoacid. The immobilized acylases obtained by the new process retain practically constant activity after prolonged (>1000 hrs) use, whereas preparations obtained in exactly the same way but using porous glass instead of aluminium hydrosilicates are inactive or lose their activity after only brief use in enzymatic optical resolution.
