Patent DE-19516262-A1 (DE)
Title: Photonic time cell selector apparatus for digital optical time multiplex signal
Inventor: SCHNABEL RONALD DIPL ING
IPC: H04J14/02
Filed: 1995-04-27
Abstract: The apparatus includes a semiconductor laser amplifier (SOA), and a switching circuit provided with an input light wave conductor connection (IN) and a coupling circuit (CC). The amplifier acts as a four wave mixer into which two function operated light waves are radiated. The light waves are of a consistent polarisation and in a mutual frequency band. The switching circuit is connected to the input of the laser amplifier. Two pump light generators are also provided with the switching circuit.  OTDM signals (S(OTDM)) are fed to the input conductor connection and the two pump light generators supply respective time correlated pulses. One generator (P1) supplies an optical pulse whose duration is at least equal to that of the OTDM signal to be selected and the duration of the other generator (P2) supplies a sensing pulse synchronously with the selected time cell.

Title: Automotive camshaft lubricating system
Inventor: PAUL MICHAEL DIPL ING
IPC: F01M9/10
Filed: 1996-05-30
Abstract: The bearing covers (2-5) are connected up into a stable bridge piece by means of struts (6), using a channel in the strut as cam oil line. Bearing oil line (9) parallel to line (18) is linked via channels (15) to the inside of the shell (12) of the respective bearing cover.

Bearing covers and one or more struts are integrally cast so the two channels can be drilled out in a subsequent pass.  In addition to the two channels, the strut or struts are fitted with a bearing cover stabilising stay. The groove (14) on the inside of each bearing shell can combine to form a ring oil channel linked in turn by the connecting channels to the bearing lubricating channel. The cam lubricating line has nozzles facing the cam to spray the lubricant onto these in service.

Title: Emergency call signalling method in trunked radio network
Inventor: SCHUMANN HARTMUT
IPC: H04W4/90
Filed: 1996-06-25
Abstract: The signalling method involves associating a location dependent emergency call contact with the hand held radio device of a mobile radio apparatus. The emergency call contact automatically triggers an emergency call with a time delay after a predetermined angle of inclination is exceeded. An emergency call button may be arranged parallel to the emergency call contact.  A direct mode channel of the radio frequency range may be used for the emergency call transmission between the hand held radio and the mobile radio apparatus and a stationary car radio. Alternatively, instead of a hand held radio, a portable emergency transmitter with an alarm and an emergency button may be used.
