Title: Verfahren und einrichtung zum synchronisieren eines mobilfunkempfängers
Inventor: BECKER BURKHARD
IPC: H04B1/707
Filed: 2003-08-08
Abstract: Bei einem Verfahren zum Synchronisieren eines Mobilfunkempfängers mit einer Zeitschlitzstruktur eines von einer Basisstation erhaltenen Funksignals über das Auffinden mindestens einer bestimmten Zeitschlitzgrenze wird ein von dem Mobilfunkempfänger empfangener Datenstrom in einem Filter gefiltert. Das Filter stellt nach der Filterung eine Entscheidungsfolge (Y) von Empfangsdaten als Menge der maximal möglichen bestimmten Zeitschlitzgrenzen bereit. Die Entscheidungsfolge (Y) wird in einem zweistufigen Verfahren derart weiterverarbeitet, dass in einer ersten Verfahrensstufe eine Untermenge (Ysub) aus der von dem Filter bereitgestellten Entscheidungsfolge (Y) ausgewählt wird und danach in einer zweiten Verfahrensstufe eine zeitliche Mittelung der Elemente der genannten Untermenge (Ysub) erfolgt, als deren Ergebnis die zur Synchronisation dienende Zeitschlitzgrenze erhalten wird. Dabei erfolgt die Auswahl der genannten Untermenge (Ysub) unter Ausnutzung statistischer Eigenschaften von solchen Signalabtastwerten, die zu einer Zeitschlitzgrenze gehören, und von solchen Signalabtastwerten, die nicht zu einer Zeitschlitzgrenze gehören.

Title: Emulsifiers for white bread dough
Inventor: WIXFORTH BRUNO
IPC: A23P10/47

Title: Drying air by freezing - esp for compressed air with continuous removal of precipitated ice
Inventor: ZIMMERMANN GERHARD DR ING
IPC: B01D53/26
Filed: 1971-05-19
Abstract: A continuous method of drying humid gases, esp. compressed air, operates by freezing out the moisture the air is cooled to a temp. below the freezing point of its required residual humidity in a coolar; the moisture is removed as ice or frost from the cooling surfaces by mechanical or pneumatic means as it is deposited and the dried air and ice are separately removed. Preferably, the air is precooled to just above the freezing point for the moisture, the negative heat energy from the dried air being optionally used in part of the pre-cooler. The humidity is partially removed as condensate. In the preferred apparatus, the precipitated ice is continuously removed from the cooling surfaces pneumatically, e.g. by pellet-bombardment, by mechanical scrapers or by having the cooling surfaces themselves elastically deformable.

Title: Circular knitting machine - with electro magnetic needle selection
Inventor: KNOUREK JAROSLAV
IPC: D04B15/78
Filed: 1971-10-08
Abstract: Circular knitting machine has electro magnetic needles selection for knit, no knit and tuck positions. There is a permanent magnet inside a pair of pole shoes. This in turn is surrounded on three sides by an electro magnet. In the opening of this unit the steel selecting jack fits. As the jacks approach selection they are attracted to the permanent magnet. This position is the knit. As the cylinder moves further, an impulse can be fed to the permanent magnet, which overcomes the force of the permanent magnet and moves the jack or selector out. This is the tuck position. The magnets can be fitted with sapphire insert to reduce wear.
