Title: Method and apparatus for transmitting data packets
Inventor: HAKENBERG ROLF
IPC: H04L12/56
Filed: 2001-07-17
Abstract: The invention relates to a method and apparatus for transmitting data packets over a channel wherein the data packets have compressed headers. After compressing a header using a context, a number of consecutive update packets are transmitted, each containing data indicating said context. According to the invention, the channel quality is determined and the number of update packets is set accordingly. The channel quality may be determined by measuring the block error rate or the signal-to- noise ratio. Alternatively, the channel quality may be estimated by evaluating whether a NACK message has been received. The total number of update and non- update packets transmitted during a context update phase may be set according to the Round Trip Time. The number of non-update packets may further be determined based on codec properties. The invention may advantageously be used over unreliable, e.g. wireless, channels.

Title: Twin delivery screws provided for installation in positive-displacement machines, especially pumps
Inventor: BECHER ULRICH
IPC: F04C18/16
Filed: 1999-12-07
Abstract: Prior art multithread twin delivery screws comprise point-symmetric profiles , small inclines, and very large angles of wrap and, due to the residual blow- hole losses between the working cells, have to be operated in a high-speed manner. Prior art single-thread embodiments seal-off work cells without the use of blow-hole connections and produce a good vacuum and a good level of efficiency when operated at average and low rotational speeds, but have a tendency to produce unwanted bending vibrations at high rotational speeds. D ue to geometric reasons, it is not possible to provide an effective inner cooli ng for any of these embodiments. The invention eliminates this deficiency and combines the advantages of both aforementioned embodiments. The invention provides a uniform solution for a broad range of rotational speeds by using delivery screws (1, 2) which are not point-symmetric and which comprises multithread front profiles with a centrical center-of-gravity. Delivery scre ws of this type function without blow-hole losses, are also suited for high-spe ed operation by virtue of the centrical center-of-gravity, and, due to the lack  of balancing cavities with average inclines, can be equipped with channels f or inner cooling. These favorable adaptations possibilities with regard to process control permit the invention to be used in the fields of medicine, chemicals and semiconductor technology.
