Title: Data communications network linking processors via single highway - functions by each processor sending own address and address of next processor due for access
Inventor: FUNK GERHARD DIPL ING
IPC: H04L12/417
Filed: 1978-02-10
Abstract: The data network links several data processors via a shared data highway. Each message states the sender and the type of message and is sent to all processors. All processors acknowledge the correct receipt of the message, check bits being included in the message. The messages are sent as blocks of constant length or a multiple of such a length. When no messages are being sent the processors are polled cyclically, whereby each is given access to the data highway. Polling occurs by each processor emitting a data packet containing its own address and the address of the processor next due for access to the highway.

Title: Identification circuit for incoming signals in telephone exchanges - briefly interrupts signal and recognises it number of signal appearances after interruption
Inventor: HOETH JUERGEN ING GRAD
IPC: H04Q3/00
Filed: 1978-05-17
Abstract: The signals have different lengths and are received by connecting line translations. They are recognised by a preliminary processing unit with a group of translations, and evaluated by a central processing unit. The beginning of an incoming signal inserts through the preliminary processing unit time marks in a central time mark store. After the time determined by these time marks has elapsed, a test pulse is applied to the translation receiving the signal. It briefly interrupts the still present signal, so that the preliminary processing unit senses a change of state and the central processing unit identifies the signal by the number of signal reappearances depending on the signal length.

Title: WC flushing cistern disinfection bottle - has relatively thick section in neck to maintain stable configuration in use when floated in water
Inventor: HOFE DIETER VOM
IPC: E03D9/03
Filed: 1978-11-16
Abstract: Plastic bottle with an open top to dispense a disinfectant or a cleansing agent into the flushing cistern of a W.C. is made of a material which pref. has a density 1% less than that of water. Pref. polyethylene or polypropylene with a density of 0.99 are mixed with a few wt. % of a chalk filler to produce a mix with a density of 0.99. The neck of the bottle has a greater wall thickness than the rest to ensure that the bottle always stands upright. A small hole in its wall halfway up ensures that every time a cistern has been flushed and the water level rises from zero to that hole, an amt. of soln. equal to the vol. in the bottle above the hole is dispensed in the water. The floating bottle can be produced at low cost and ensures an even dispensing at each flushing operation.

Title: Solar energy collecting system - vaporises fluid in collector, and uses liq. falling from condenser to drive turbine
Inventor: REIS AUGUST PROF DR MED
IPC: F03G6/00
Filed: 1979-05-11
Abstract: The solar energy collection system uses a working fluid which is vaporised and after condensation drives a liq. turbine. The vaporising device consists of solar heat collection plates set at a low level, and the vapour leaving this device flows upward to the condenser which is at a considerable distance above the vaporiser. The liq. leaving the condenser falls downward to drive the turbine which is approx. at the same level as the vaporiser. After giving up the kinetic energy acquired during its fall, the liq. then returns to the vaporiser. The turbine drives a generator in the usual way. The liq. is pref. either phenol or alcohol.
