Patent WO-2005027432-A1 (WO)
Inventor: MENTH MICHAEL
IPC: H04L12/54
Filed: 2003-11-21
Abstract: The invention relates to two methods which improve the load of a link with access control and/or a communication network with access control. According to the invention, overbooking according to the ratios of the measuring values of transferred aggregated traffic is determined according to the face values of aggregated transferred traffic. The ratios of measuring values in relation to face values are weighted according to the variable of either the measuring value or the face value such that with smaller measuring values and/or face values the ratios thereof have a slightly lower effect on the determination of overbooking than the ratios of greater measuring values and face values in relation to each other. The invention provides systematic access for the improved use of wave bands. Representative situations, wherein a high charge of the wave band is predominant, are taken into to account to a greater extent during the determination of the overbooking factor than by phases characterised by a small load.

Patent DE-2125522-A1 (DE)
Title: Centrifugal separator - with by-pass chamber esp for machine tool coolant with swarf
IPC: B04B1/14
Filed: 1971-05-22
Abstract: As the centrifuge chamber becomes filled with swarf the entry to it from the main inlet becomes narrowed and the liquid is diverted through the bypass chamber which forms part of a resonant ultra sonic circuit with sensors which detect falling away from resonance as the liquid in the bypass exceeds a threshold value. These signals are used to actuate an axial door at the base of the centrifuge through which the swarf falls undfer gravity. This door at the same time closes the inlet to the centrifuge proper so that the liquid flows either through the bypass or into a second centrifuge chamber. Automatic self cleaning is achieved.

Title: Flash socket for miniature camera - is fitted to built-in extension arm for increased objective-bulb distance
Inventor: LERMANN PETER DR
IPC: G03B15/04
Filed: 1973-08-01
Abstract: The extension arm carries a rotating flash socket for multi flash cubes at one end. The arm is pivoted to the camera body so that it fits flush when not in use. In an alternative construction it is made to slide in and out of the camera body. The extension arm encloses transmission spindles which link the rotating drive mechanism in the camera with the socket and the percussion firing impulse from the striker to the bulb socket. The greater spacing between the flash unit and the camera objective improves the parallax and close-up colour rendering. The design avoids the use of separate small attachments which are tedious to fit and can get lost.

Title: Moisture level control in potted plant containers - anode and cathode provide capillary action to transfer moisture and voltmeter indicates moisture level
Inventor: HAMPEL GEORG
IPC: G05D22/00
Filed: 1973-11-09
Abstract: A copper strip which serves as an anode is located in the mineral particle base layer and a zinc strip is embedded in the peat based top layer. Connections from both anode and zinc cathode are coupled to a voltmeter than records a potential difference dependent upon moisture level. A central tube of plastic acts as a support for the anode and cathode. Due to electro-osmosis moisture accumulated in the base layer will be transferred by capillary action to the top layer.
