Patent WO-03017523-A1 (WO)
Inventor: ECKERT MICHAEL
IPC: H04B7/26
Filed: 2002-07-09
Abstract: The invention relates to a method for adapting uplink signaling during multicasting, according to which the user devices of a multicast group receive a multicast message from a network control unit via a radio channel (PMcCH) in a downlink connection. Said radio channel is adapted with respect to its power by transmitting information in an uplink connection via a corresponding radio channel (UL-DPCCH). According to the invention, said radio channel (UL-DPCCH) is power-controlled via at least one associated common radio channel (DL-PMcCH) that is associated with one or more of the user devices by transmitting corresponding information in the downlink direction from the network control unit to the user devices. Said information is then processed by the receiving user devices to adapt the power of the respective associated radio channels (UL-DPCCH) in the uplink direction.

Title: Fluids mixing tube - spacing and setting of internal mixing blades related to reynolds number
IPC: F15D1/02
Filed: 1971-04-21
Abstract: In a fluids mixer of the type in which a tube is fitted with internal curved blades to mix a fluid passing through the tube, the leading edge of a second and any succeeding blade is substantially spaced from the trailing edge of the preceding blade. Spacing and angular displacement of successive blades is a function of the Reynolds number of the fluid for optimum mixing, e.g. spacing may be three times tube diameter for "Re" = 10, up to six time sthe diameter for "Re" = 200 to 300. Fewer blades for adequate mixing result in cheaper mixer which also offers reduced flow resistance as an in-line mixing tube.

Title: Beer barrel cleaning appts. - spray pipe incorporates gas vent valve
Inventor: SCHAEFER MANFRED
IPC: B08B9/093
Filed: 1973-07-09
Abstract: The cleaning fluid enters the container by a pipe which passes through the upper end surface of the container. The lower end of the pipe carries a spray head or nozzles. An opening in the side of the pipe forms a valve seat which cooperates with a spherical valve the travel of which is restricted by a support. The ball normally rests on the support so that when the container is full of beer the fermentation gases can escape through the open valve and out through the pipe. When cleaning fluid is introduced the pressure closes the valve ensuring that fluid flows through the spray head.
Patent DE-2336604-A1 (DE)
Title: Spring loaded lever pivot for data handling machine - eliminates play and achieves constant reproducible motion
Inventor: MUGRAUER HUBERT
IPC: F16C11/04
Filed: 1973-07-18
Abstract: The lever is provided with a hole slightly larger than the pivot bolt so that there is a small clearance between hole and bolt. A wire spring which surrounds the bolt has a hook bent at right angles which fits into a small hole in the lever near, and parallel to, the bolt hole. The action of the spring pulls the lever hard against one side of the volt so that when a turning moment is applied to the lever it pivots about the bolt surface avoiding lost motion and preventing accumulation of solidified lubricant which also causes variable output motion.
