Title: Telephone switching system with central data carrier - has logic circuit combining request signals to produce free signal only when one request signal is present
Inventor: OSCHLIESS ARNOLD DIPL ING
IPC: H04Q3/545
Filed: 1977-04-07
Abstract: The telephone switching system has devices of a first kind (data carrier drives) arranged centrally w.r.t. devices of a second kind (central drives). The latter are provided with request lines. The devices of a first kind have inputs equal in number to the number of request lines. The inputs are connected to the inputs of logic network that combines simultaneous request signals with one another in such a way that only when one single request signal is present does a 'free' signal appear at the output of the logic. This 'free' signal is passed to all the devices of a second kind via a shared line.

Title: Atomising light oil burner - has secondary air outlets in inner wall of fire tube in front of flame baffle
Inventor: DOLFEN HANS-PETER
IPC: F23D11/40
Filed: 1977-09-15
Abstract: The light oil burner of the pressure atomisation type ensures improved operation for small boilers using a double-walled fire tube insert (2). The air outlets (7) of the inner wall (4) are in front of the flame stabilizing baffle (13), while inside the wall (13) is the adjustable air control valve. Improved mixing and stable flame are achieved with secondary air supplied through outlets (7) while the primary air is fed through the inside of the fire tube. The air control valve allows lower pressure of primary air to be used for atomization of the fuel, and a short flame allows installation in combustion chambers with a length of 20 cm to be carried out. The intensity of mixing is controlled by the shift of the nozzle (10).

Title: Gas stream control valve system - has three annular housing sections with common camshaft actuating valves
Inventor: INDREHUS DAGFINN
IPC: B01D53/04
Filed: 1978-04-26
Abstract: The valve system changes gas currents between two vessels to direct gas under pressure into the first one and a smaller current at lower pressure in the opposite direction into the second one, also periodically shutting off the discharge from the second vessels and equalising the pressure in the two. The gas current is then diverted from the first to the second and the outlet from the first opened, to allow a reduced current at preduced pressure through it. Three annular valve housing sections in a row (4, 10, 18) contain a common rotary camshaft (22) for the valves in each. The first section (4) incorporates the inlet (12) for the gas to be processed and outlets (11, 14) to each vessel (1, 2), together with a plug (7) shutting off one or the other of the outlets.

Title: Sliding support arm for hinged furniture flap - is twisted at top, for braking action inside guide slot at end of travel
Inventor: ZERNIG ERNST
IPC: E05C17/22
Filed: 1978-10-06
Abstract: The sliding arm (5) which acts as a stay to support a hinged flap in a horizontal position, for e.g. a cupboard, passes through a guide at the top which also acts as a brake as the flap nears its horizontal position.
