Patent DE-19601786-A1 (DE)
Title: Pneumatic audio graph linearisation for music reproduction
Inventor: SCHAEFER WALTER
IPC: H04R3/12
Filed: 1996-01-19
Abstract: The method involves feeding the music signals from a music source (1) which are passed to an amplifier to a reproduction unit (6,7) consisting of at least one loudspeaker (8,9) under gain control. A separate signal is tapped from the amplifier without regulation and processed as an auxiliary bass signal for a low tone frequency range. The auxiliary bass signal is fed to an additional low tone loudspeaker unit (12) where it is reproduced with an adjustable level. The auxiliary bass signal cab be fed to the low tone loudspeaker unit via a separate regulator.

Title: Urn burial by raising urn to extreme height
Inventor: GUENTHER HARRY H
IPC: A61G17/08
Filed: 1996-01-24
Abstract: The filled urn (1) is lifted to a great height and there opened to liberate the ashes, using a balloon (3), rocket or model aircraft to raise the urn. The urn bursts or splits open due to the extreme underpressure at this height, or else is exploded at this level by an explosive charge (4). The urn can also open by combustion charge triggered by a delay fuse or pressure fuse. When a rocket is used to raise the urn, the propellant charge can be used on expiry to open the urn. The urn can open up automatically and has an ideal break point or is sealed shut against pressure and can be equipped with charge or made of pretensioned glass or combustible material as appropriate to its opening mode. The fuse (5) is impregnated against wind or moisture and is of pre-set length to determine firing height.

Patent DE-19608652-A1 (DE)
Inventor: STRAUS ANDREAS DIPL ING
IPC: F01L1/344
Filed: 1996-03-06
Abstract: In a device (1) for modifying the opening and closing times of gas exchange valves of an internal combustion engine, high-frequency knocking of the regulating piston at one of its end positions when the engine is started again is to be avoided by simple means. For this purpose, a slide (18) secured against rotation in relation to a section (19) of the housing connected to a driving wheel (2) is mounted in one of the pressure chambers (15, 16). This slide (18) can be positively coupled to a driven unit (12) by the force of a compression spring, against the falling pressure of the hydraulic medium. This prevents the regulating piston (8) from moving further in the axial direction immediately after the internal combustion engine is started and until the device (1) is filled again with hydraulic medium, thus preventing the high-frequency knocking of the piston at its corresponding end position.

Patent DE-19651126-A1 (DE)
Title: Serial, bi-directional data transmission method
Inventor: MEYER WOLFRAM DIPL ING
IPC: H04R25/00
Filed: 1996-12-09
Abstract: The method involves using a programming device to transfer data as well as clock pulses to a usage instrument, such as a hearing aid, for the individual adjustment of application-specific data of the usage instrument. A single signal line is used for the data transmission, whereby differently formed clock pulses are put on the signal line. The digital information is recovered at the receiver side by use of clock pulse variation, and is subsequently processed with the transmitted clock. A clock pulse variation is performed by the usage device on the clock pulses send by the programming device at an occurrence of a receive signal. The information encoded in the clock pulse variation is recreated in the programming device for the return path of the data transmission between the programming device and the usage device.
