Patent DE-2724867-A1 (DE)
Title: Colour improvement of organic liquid - by refining, hydrogenation and treatment with solid adsorbent followed by electrofiltration
Inventor: WAGNER OLIVER
IPC: C11C3/12
Filed: 1977-06-02
Abstract: A non-petroleum organic liq. is hydrogenated and purified by first refining it to remove gross impurities. The refined product is mixed with a finely divided hydrogenation catalyst and a finely dispersed absorbent. Hydrogenation occurs in the presence of hydrogen at an elevated temp. to produce a hydrogenated product carrying the entrained catalyst and solid absorbent. The mixt. is subjected to electrofiltration in an oxygen-free atmosphere for the complete removal of the hydrogenation catalyst and solid absorbent from the hydrogenated product. the resulting product is solids-free and colour improved. There is no mechanical filtration of the liq. and associated problems are avoided. The process gives substantially complete removal of even very small suspended solids.

Title: Composite gold and platinum jewellery - is made by heating gold on platinum as support until it melts and fuses
Inventor: EXNER GEB NIESSING URSULA
IPC: A44C27/00
Filed: 1977-07-26
Abstract: The jewellery such as a ring is made by applying the gold in the solid state onto the platinum which is the support metal and then heating the gold up to its melting temp. The finished ring then has the full lustre of gold without the need for any subsequent finishing such as polishing. The melted gold bonds tightly with the platinum.

Title: Monitoring system for programme operating cycle - uses monitoring counter to achieve specific state by end of programme cycle as determined by clocked time base
Inventor: SATTLER WALTER DIPL ING
IPC: G05B19/042
Filed: 1978-10-23
Abstract: The monitoring system is used to check for operational malfunction of the operating cycle of a programme used in teletype. A programme counter (PC) is cycled to provide addresses to identify programme steps. The programme counter is controlled by signals from a clock generator (Tg1) providing the time base of the system. A decoder (Dec) coupled to the output of the programme counter is set to identify specific counter states that are then used to set a flip flop (FF). The set condition of the flip-flop causes a switch (SWZ) to be open thus allowing pulses from a separate generator (Tg2) to operate upon the monitoring counter (Cnt). The state of the monitoring counter is continuously changed to attain a specific condition at the end of the programme cycle. This results in the switch controlling the programme counter signal generator being opened.
