Title: Glucose-isomerase prepn using streptomyces
IPC: C12N9/92
Filed: 1970-04-13
Abstract: Micro-organisms of the genus Streptomyces are cultured in stages under submerted aerobic conditions in an aqueous nutrient medium, whereby in at least the last growth-stage a carbohydrate source is present, obtained from a hydrolysate of a xylan-contg. material. Pref. hydrolysate is an acid hydrolysate and micro-organisms used are pref. able to assimilate xylan. Pref. microorganisms are Streptomyces ATCC 21175 and ATCC 21176. The acid hydrolysate used may be a filtered, non-purified hydrolysate obtained by acid hydrolysis of cotton seed husks, rough fibres from wet-milled maize, etc. In the initial growth stages ca 0.05-0.25% of a non-nutrient material such as carboxymethylcellulose is pref. added to encourage the growth of a fibrous mycelium. The glucose-isomerase produced is used for the isomerisation of glucose in glucose syrup for the foodstuff industry. The process is economical and gives high yields.

Title: Windscreen wiper intermittent operation - has stop switch connected to vehicle mass and transistor emitter connection with stop switch contact leaf
Inventor: KOOB WERNER
IPC: B60S1/08
Filed: 1973-09-27
Abstract: The arrangement can be installed on any standard-make wiper motor. The capacitor is directly connected with the circuit of the wiper motor, ensuring t hat the capacitor has time to charge up during the operation of the motor. By connecting the contact leaves of the reversing relay and those of the stop switch it is ensured that there always exists a current passage for the wiper motor. When the stop switch stops the motor operation, the capacitor starts discharging and the base of the transistor receives an incr easing positive potential, which at some point makes the transistor conductive and a new starting impulse for the reversing relay follows.

Title: Switching cct. for defroster of vehicle rear window - uses single pole relay with coil in ignition loop
Inventor: KERSCHER MAX
IPC: H05B3/84
Filed: 1973-10-05
Abstract: The circuit is for switching the defroster element of the rear window of a motor vehicle into and out of circuit, with ignition switch override. The circuit incorporates a relay whose single pole contacts switch in the battery supply to the element circuit. The relay coil is in a control loop with the ignition switch. One branch of the control circuit is activated by a pushbutton which will energise the relay coil. Another pushbutton has its contacts on the element side of the relay contacts holding the relay in via its own contacts. This can break the current through the relay coil. The on switch is shunted by a diode or a transistor switching circuit.

Title: Connector for H.T. ignition cable - comprises a tubular cable insert and a contact pin
Inventor: HERRMANN GERHARD
IPC: H01R4/50
Filed: 1974-03-11
Abstract: The object is to simplify the connection, especially when the connecting pin is integral with the ignition coil. The contact sleeve has a pointed end with a circumferential recess and is pressed into the cable core until the cable end bears against a flange at the opposite end of the sleeve. The elasticity of the cable insulation holds the sleeve in position. The bore of the sleeve is practically identical with the pin diameter, thus when pushed over the latter a contact in the maner of a plug and socket is formed. To assist contact pressure the sleeve may have longitudinal slits extending from the flange to near the recess. The pin is typically surrounded by an insulation shroud.

The pref. device consists of a burner in a mounting which can be automatically rotated to maintain the angles (alpha t) and (alpha n). Cutting of complex shapes at high speed, viz. about 900 mm/minute depending on the thickness of the sheet. Accurate dimensions of the cut part with very little rounding of the edges and the flash is blown off the edges by the oxygen jet.
