Patent DE-4111720-A1 (DE)
Title: Triggering identification unit responding to specific frequency signal
Inventor: CACCIAMI ERCOLE
IPC: G07C15/00
Filed: 1991-04-10
Abstract: An electronic trigger unit of the type used in games has a microphone supplied from a remote transmitter. The receiver module has a fitter input stage that eliminates background noise in the signal transmitted to a signal decoder.     The decoder outputs coupled to exclusive-OR logic gates. Other inputs are provided by switches that allow a particular signal code to be set.

Title: Appts. to convert manure to gas and ash - has roof shaped guide to feed combustion air from the side with gas moving down in horizontal planes for removal
Inventor: EICHLER DIETRICH DR
IPC: C10J3/26
Filed: 1991-04-26
Abstract: Appts. to convert fuel into gas and ash, in a generator with increasing gasification and the passage of the gas through a hot zone at about 1200 deg.C., has the air required for combustion fed in from the side at the level of the combustion zone, through a roof shape which is angled to be open at the bottom to move horizontally through the fuel to be gasified. It then passes with the gas through a channel in the opposite side to the next lower level within the roof shape on a horizontal plane, and then through side channels into the underlying plane within the roof shape for extn.. Pref. the gap between the levels in the roof shape is structured so that, at each plane, the dominating pressure difference moves part of the gas through side channels into the next lower plane while another part of the material passes directly through. Each lower level within the roof shape is displaced to break down the fuel flow. The channels at the ashes level have a large cross section to reduce the gas flow speed, with intermediate walls open to the top to form a chicane to separate out dust particles in the gas channels. The amt. of ash removed is controlled through the temp. at the combustion zone, and a vibrator assembly assists with ash removal. USE/ADVANTAGE - The system is to vaporise fine grain fuel material, where low temp. gas is passed through a hot bed at about 1200 deg.C to be given a pyrolitic conversio into CO, H2CH4, such as in agriculture where manure with a solid content of about 75% can be converted into a non-hazardous gas which can be used to generate electricity.

Title: Cellular time division radio system - carries out automatic synchronisation of radio transmitters using received data telegrams
Inventor: SCHWARZ GOTTLIEB DIPL ING
IPC: H04B7/26
Filed: 1992-05-13
Abstract: The system has at least one radio centre (FZ), addressable radio transmitters (FS) and addressable single channel signal receivers (FE).

The receiver (FE) intercepts the telegram (DT) directly or via one or more transmitters (FS) and analyses it. Each telegram (DT) includes a time division criterium (K1) which characterises the current time slot (ZS1) of the transmitting centre (FZ) or repeater (FS). The time division criterium (K1) evaluated by the transmitter (FS1, FS2) within range synchronises the transmitters. The transmitter (FS1) addresses by a route address (W) of the telegram (DT) temporarily stores the telegram data, inserts its own criterium (K2) instead of that (K1) of the centre (FZ1) and transmits the new telegram (DT2) in its allocated time slot (ZS2). ADVANTAGE/USE - Reduces cost of and simplifies synchronised transmission stations operating at same frequency. Esp. for radio alarm systems, etc.
