Patent DE-2335197-A1 (DE)
Title: District heating system heated by steam condenser - is maintained at pressure by injection of condensate in a closed cycle
Inventor: KUENKLER ALFRED
IPC: F24D9/02
Filed: 1973-07-11
Abstract: Steam from a power plane in a closed cycle heats the district heating water which flows to e.g. a radiator and returns to the condenser. The condensate returns to the power plant through a condensate pipe. The flow of condensate is regulated by a valve controlled by the temperature of the heating water flow. A connection links the condensate return to the heating water flow so that loss of water from the heating system is made good by the addition of condensate. The condensate is kept at the pressure of the heating system by a pressure regulating valve which is controlled by the pressure in the heating system.

Title: Sonic wave powered aircraft - which burns any fuel and has vibration valve plate to generate thrust
Inventor: MUELLER MAX FRIEDRICH
IPC: B64C39/00
Filed: 1973-07-11
Abstract: A variety of fuels can be burnt to generate a fast gas flow directed downwards through a pipe. A plate is loosely held at a spacing from a fixed plate fitted to the bottom of the pipe, and secured by lips on the rim of the fixed plate. The gas stream spreads outwards over the loose plate and lifts it by a venturi effect until the pipe is momentarily closed. The airstream then pushes the plate down and sets it vibrating. This generates a pattern of sonic waves on which the craft rides at a controlled height. Vents in the lip of the fixed plate are directed outwards and downwards to trim and steer the craft. The system can be used for hovercraft and require no roadbed.

Title: Adaptive control of linear motor drive - uses analogue model to provide information for adjustment of system dynamics
Inventor: SENATORI LUCIANO DR ING
IPC: G05B13/04
Filed: 1974-03-19
Abstract: An adaptive control system is employed to control a linear motor drive for transportation systems. The controller has a number of inputs representing reference data and a feedback relating to the air gap between the electromagnetic field devices and the rail. A control signal is generated to regulate the strength of the field. Due to the high transportation velocities employed and the small air gaps and adaptive dynamic model of the system is coupled in to provide adjustment of the control unit. The analogue model describes the dynamic of the electro-magnetic field in terms of voltage, current, air gap, magnetic field strength and output force. The unit ensures that the air gap is maintained within a predetermined permissible range.
Patent DE-2414746-A1 (DE)
Title: Clearing circuit for telephone PBX - has delay line operated by extension which disconnects it when given time from loop closing is exceeded
Inventor: SCHMIDT PETER
IPC: H04M3/12
Filed: 1974-03-27
Abstract: The disconnection is performed if the number is no dialled during the given time. The delay line breaks the holding circuit of the extension relay, and short-circuits its winding by a switch parallel to it operated by the delay line; this switch is a thyristor ignited by the delay line and the delay line opens a switch in the holding circuit, or alternatively the delay line blocks a transistor in the holding circuit. The system ensures that the PBX always returns to a cleared state if dialling of numbers is interrupted and not resumed, thus preventing permanent jamming of numbers.

Title: Digital time multiplex method - designed for transmission and storage of signals esp. speech and pictures
Inventor: GERHAEUSER HEINZ L DIPL ING
IPC: H04N7/52
Filed: 1974-06-27
Abstract: Transmission or storage capacity is for at least one scanning point distributed by prediction circuits between individual signal sources with variable word length in accordance with past signal behaviour. Greater word lengths are allocated to greater absolute or relative difference values of signal amplitudes to be transmitted, and words allocated to individual signal sources are used for transmission of coded differences from the estimated value, or from the signal coded absolute values. The sum for variable word lengths is the same for every scanned value. The word length is determined on grounds of expected difference values.

Title: Artificial oxygenator for blood - being rotating spiral of film over which blood is trickled
Inventor: WOLTER HANS KARL PROF DR
IPC: A61M1/32
Filed: 1974-07-17
Abstract: Gas exchange, absorption, solution or degassing into a liq. surface is carried out by covering a coiled film with the liq. and this then presents a large surface area to a gas or gas mixt. The spirally coiled film is rotated, drawing liq. up into it and passing it down its length by the rotation. A liq. or gas can be used as catalyst. The liq. can be blood, for which the gas should be O2 or an O2 contg. mixt. The device can serve to exchange CO2 and O2 in blood e.g. as an oxygenator in a heart and lung machine. For major heart surgery, a substitute pump and oxygenator is reqd. Commonly used systems have problems. wire mesh systems generally present inadequate surface area and thus poor oxygenation. Similarly rotating discs are inadequate for adult requirements. Using a film across which transfer occurs generally gives different transfer rates for CO2 and O2. Direct O2 injection results in haemolysis. The method described improves on all these methods by distributing the blood over both sides of the film surface. Froth formation is low.

Patent DE-2459976-A1 (DE)
Title: Open end spinning device fed with fibres from opening roll - has deflector surface against which waste is flung from opening roll
Inventor: SRAITR STANISLAV
IPC: D01H4/36
Filed: 1974-12-18
Abstract: A spinning rotor of an open end spinning device is fed with discrete fibres passing through a feed duct connecting with a cavity of a housing in which an opening roller is mounted, the discrete fibres being produced on the periphery of the opening roll by opening a sliver fed to the opening roll. Heavier waste in the sliver is flung from the opening roll against the cavity wall and passes across the mouth of the feed duct and strikes a deflector surface downstream of the feed duct. The deflector surface directs the waste into a waste removal duct through which it is exhausted. Arranging the waste removal duct downstream of the feed duct provides a more compact arrangement. The deflector surface ensures that the waste passes into the waste removal duct and doesn't stay in the cavity in which the opening roller is mounted.
