Title: Verfahren sowie mikroorganismen zur mikrobiellen herstellung von pyruvat aus kohlenhydraten sowie alkoholen
Inventor: GERHARZ TANJA
IPC: C12P7/40
Filed: 2003-04-17
Abstract: Die Erfindung betrifft ein Verfahren sowie Mikroorganismen zur mikrobiellen Herstellung von Pyruvat aus Kohlenhydraten sowie Alkoholen. Die nach dem Stand der Technik bekannten chemischen Verfahren zur Herstellung von Pyruvat sind technisch aufwendig und kostenintensiv. Die bekannten biologischen Verfahren sowie Mikroorganismen weisen den Nachteil auf, daß die Substrate nicht zu 100 % in Pyruvat umgesetzt werden und dadurch die Produktausbeute verschlechtert wird. Außerdem ist bei der mikrobiellen Pyruvat-Produktion aus Glucose eine aufwendige Steuerung der erforderlichen Vitamin-Konzentration notwendig. Mit dem erfindungsgemäßen Verfahren und den Mikroorganismen ist es möglich, mikrobiell Pyruvat mit einer nahezu 100%igen Umsetzung des Substrates herzustellen. Durch Verwendung von Mikroorganismen, die genetisch verändert wurden, d.h. Deletion, Insertion bzw. geringere Expression der 1dhA-Gensequenz, die für die Lactat-Dehydrogenase kodiert, konnte eine erhöhte Pyruvat-Produktion erreicht werden.

Title: Water-cooled housing for hot blast slide valve - using two pairs of water channels for high heat transfer
Inventor: WOLTER HEINRICH
IPC: C21B9/12
Filed: 1973-12-28
Abstract: A water-cooled housing for a hot-blast slide valve, esp. a valve working in a blast duct provided with a refractory lining, uses four annular, concentric water-cooling channels in two pairs, one pair being located on each side of the slide, the four channels being connected one behind the other in the same cooling circuit. Alternatively, the inner cooling channels of each pair may be connected together and may also contain dividing walls to direct the water flow. The water can flow in various ways through the channels and two separate water circuits may also be used; the system can also be applied to several slide valves, i.e. where water travels between the channels in each valve. Used on both high temp. e.g. 1500 degrees C and low temp. e.g. 650 degrees C blast ducts, the flow of cooling water being altered to suit the application.
Patent DE-2405281-A1 (DE)
Title: Drive for automatic door opener - has single or multiphase motor whose speed is varied by phase angle shift
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: H02P27/02
Filed: 1974-02-04
Abstract: The system is used for swivelling hinge doors or for sliding doors. The door is rapidly opened and its last stage in the opening movement is relatively slow. The speed is controlled by using a single or multiphase alternating current motor whose rotating speed can be adjusted by supplying direct current components and alternating current components. The direct current proportion can be varied by a phase angle shift actuating system. This arrangement simplifies the actuating system and a small number of electrical components eliminate the use of a braking cylinder. The motor has a pole change arrangement for changing the rotating direction. Separate phase angle shift control systems are used for determining the basic speed on opening and closing and for establishing the damping speed at the end of the opening and closing movement. The phase angle shift control systems are connected to different phases of the three phase current supply.
Patent DE-2407663-A1 (DE)
Title: Sieving extruded plastics on way to mould - using sieve which is continuously back flushed one hole at a time
Inventor: WENDE PETER DIPL ING
IPC: B29C48/11
Filed: 1974-02-18
Abstract: A sieve for plastics processing machines, esp. extruders is fitted between the extruder and the mould. A moving assembly comprising sieve frame, sieve and sieve support plate has a number of parallel rows of holes which constitute the sieve for filtering inhomogeneities out of the plastics. During the extrusion process, this assembly slides slowly relative to the fixed housing so that each row of holes in turn becomes aligned with a row of discharge passages in the fixed housing, which discharge to atmosphere. These passages are on the upstream side of the sieve which, in this region, is cut off from the supply coming from the extruder; thus the flow is reversed through the sieve holes aligned with the passages, causing these holes to be back-flushed. A control valve enable the individual holes of a row to be connected to atmosphere one at a time.
