Patent DE-2701615-A1 (DE)
Inventor: HIGASHIDE CARLOS S
IPC: G06F3/12
Filed: 1977-01-17
Abstract: To be able to transmit the data to be printed out by a number of printers at the one time, the central processing unit outputs addresses which are allocated to the printers selected for the printing; furthermore, it transmits the data to be printed to the printers via a common transmission line. Each printer exhibits an address field identifying it. When an address is received via the transmission line, the received address is compared with the printer's own address field in order to determine whether this printer is addressed by the central processing unit. If this is so, a latch is set which enables the printer control circuit for the data reception and the data printout to process the data transmitted by the central processing unit. When the latch is set, the printer waits for transmitted data. This latch remains set even when the central processing unit is addressing other printers for printing out data so that the printer already addressed continues to wait for the reception of data. If all selected printers are addressed, the central processing unit transmits data which are received and printed out simultaneously by each printer addressed.

Title: Fibrous fleeces on carriers for absorbent disposable(s) - transferred by compressed air cushion from gauze to carrier
Inventor: SCHULZ HANS
IPC: D04H1/732
Filed: 1977-02-01
Abstract: For the production of materials to be used as adsorbent, disposable underlays in hospitals, etc., the webs of fibres laid on a carrier, are deposited first of all with the help of a current of air, on to an endless gauze belt. This web is then transferred to a moving band of tissue, fleece material or film supported by an endless belt; the fibrous web being released from teh gauze with the help of a current of gas or air. The plant comprises an endless running gauze on driving and guiding rollers, a depositing station for the fibre and can ancillary belt close to the gauze, on to the surface of which a continuous band of paper, fleece or film runs. Close to the transfer point there is >=1 guide cylinder for the gauze, having a perforated mantle revolving on a fixed core. In the core there is a chamber aligned towards the transfer zone for the web of fibres, connected by a line to supply of compressed air or gas, whilst the parts of the mantle which are not directed towards to transfer zone are covered. Makes the transfer of the fibres which are laid down in the dry state, esp. when there is a large proportion of short fibres, much more efficiently.

Title: Control circuit for induction motor torque and rotation - has windings supplied directly by operational amplifiers which can be operated in inverting or non-inverting mode
Inventor: HEIDE JOHANN VON DER DIPL ING
IPC: H02P23/24
Filed: 1977-04-27
Abstract: The induction motor is esp. an eddy current motor with n windings, where n is at least two. Motor windings (33, 34) are directly supplied from power operational amplifiers (21, 24).

Patent DE-2719668-A1 (DE)
Title: Low compression ratio four stroke Diesel engine - has two groups of cylinders one of which is used for precompression at part load
Inventor: RINSUM CORNELIS VAN DIPL ING
IPC: F02D23/00
Filed: 1977-05-03
Abstract: The cylinders of a four stroke diesel engine are divided into two groups (21-23, 24-26). At low loads the air from the turbocharger compressor (14) passes through one group (25-26) in which it is compressed and is delivered from this to the second group (21-23) in which combustion takes place. The air enters the first group through the inlet manifold (21) and leaves through the exhaust manifold (19). At full load, air from the turbocharger compressor (14) enters all cylinders and combustion takes place in all of them. The change in flow from part to full load is obtained by three way valves (27, 28) in the inlet and exhaust pipes. The system enables a low compression ratio engine to work at part load without complicated valve timing controls.

Title: Telecommunication pulse length detector - uses single timing member for indicating pulses which are too short and too long
Inventor: NIELSEN ANDERS KOLDBY DIPL ING
IPC: H04Q1/32
Filed: 1977-06-29
Abstract: The multivibrator is effective for the duration of a pulse is connected to a first decadic counter which detects a pulse of too short duration, and via a first flip-flop circuit halving the oscillations of the multivibrator to a second decadic counter which detects a pulse of too long duration. A second flip-flop circuit evaluating the outputs of the counters is connected to follow the first and second decadic counters via respective junction members. This enables one timing member to be used for pulses which are too short and too long, whereas previously individual timing members were required. The timing member may be made from commercially available components which require little supervision of their adjustment.
Patent DE-2730095-A1 (DE)
Title: Pumped laser for anti-aircraft defence - utilises neutrons for pumping to minimise risk to human life
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H05H1/22
Filed: 1977-07-02
Abstract: The parent Patent relates to a weapons laser for aircraft and rocket defence. In this Patent of Addn., an enveloping and controlled fission reactor generates neutrons and these are used, instead of optical light, for the pumping process; this means that the laser gas casing need not be transparent. This non-transparent casing for the gas is surrounded by an annular space of great axial length, with an energy pellet mounted to receive the incoming laser beam coaxially placed at one end of the assembly. The effect of the pellet is to generate a rapidly expanding and cooling plasma in the annular space; the laser gas chamber is thus exhausted and the laser beam is pumped. By carefully metering the emission of neutrons the risk to human life around the appts. is elimianted.

Title: Prodn. of wire wound HF chokes and other components - involves automatic insertion of two tinned metal pins in core blind holes and insertion of coils in series without gaps into drying oven
Inventor: SILLNER GEORG RUDOLF
IPC: H01F17/04
Filed: 1977-07-09
Abstract: The coils have each axial leads and a former. Two short cylindrical thinned metal pins are automatically inserted into and fastened by, e.g. glueing, in blind holes of the former. Individual coils are automatically, and without gaps between them, placed in a drying oven. Being close together they cannot move and the pins cannot fall out. The formers are automatically fed to a winding station. During winding they are aranged next to each other without gaps and continuously passed through the winding position. The wound wire is fastened to the pins during the components passage through a further drying oven. The endless series of coils so produced is cut into individual ones. A copper lead is fastened at each end of the individual coil immediately after the winding process, or later.
