Patent DE-2532210-A1 (DE)
Title: Optical cable has glass core enveloped in a mantle - comprising a fluoro polymer and having smaller index of refraction than the core
Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1975-07-16
Abstract: An optical transmission element features a glass core surrounded by a mantle comprising a material whose index of refraction is smaller than that of the core. Specifically, the core consists of a glass-fibre strand, and the mantle is loosely applied envelope of a fluoro polymer. The element is used in the transmission of communication signals and control impulses. It combines high optical quality with mechanical strength. Facilities simple and easy connection and coupling techniques. Occasional accidental, rupture of individual glass fibres is not critical for effective performance.

Title: Electronic dice for board games operated by pressing a button - with delays indicating result for a certain time after button release
Inventor: PETERREINS MANFRED RUDOLF
IPC: G07C15/00
Filed: 1975-08-23
Abstract: The dice consists of a six-position cyclic electronic counter (C) which receives pulses (from IG) only while a gate (SP) is open and a button (WT) depressed. This counts too fast to be controlled by the button. By the invention, the release of the button closes the gate and stops the counting, and also sets up a delay (T1) which must elapse before the result is indicated. The display is held for a further time (T2) before the gate is re-opned and the button again becomes operative. Thus the button cannot effectively be pressed twice during the same throw. A variant serves for games that use more than one dice. Another provides a button for each player and a relay circuit to make them operative only in proper sequence.

Abstract: Continuous prodn. of CaSO4.2H2O from spent H2SO4 (e.g. from organic synthesis) and a spent calcium cpd., esp. from carbide mud, with the use of nucleating crystals, is improved in that the nucleating crystals (CaSO42H2O or crystalline gypsum from chemical processes) are added only once, at the beginning of the process. Subsequently, the overflow (contg. suspended CaSO4.-2H2O crystals) is continuously withdrawn and filtered. The coarse CaSO4.2H2O crystals are removed, whilst the filtrate contg. fine CaSO4.2H2O crystals is returned to the reactor where these fine crystals act as nucleating crystals. The product can be dehydrated to CaSO4.O.5H2O and used for various purposes.

Title: Injection moulding thermosetting and elastomeric materials - preventing spew fin formation by delaying sec. press. until viscosity has increased
Inventor: MENGES GEORG PROF DR ING
IPC: B29C45/57
Filed: 1976-03-23
Abstract: During the moulding by injection of masses of elastomeric and other thermosetting materials, as soon as the mould cavity is filled volumetrically, the press. in the mould cavity is reduced. The sec. press. is only applied when the viscosity of the shot has reached the point at which the mass can no longer flow along the walls of the mould. The viscosity of the mass. dependent upon temp. and time is obtd. in separate tests by press. detecting instruments. Or the point in time at which the sec. press. is to be applied, is determined experimentally when spew ribs are not formed at the joining surfaces of the mould sections. The sec. press. may be raised to that of the melt in the worm chamber - 1,000 to 2,000 bars, and it may be a pulsating press. with a frequency of 1-10 Hz. It becomes possible to use elastomeric and thermosetting material generally without formation of ribs and webs at the joining surfaces of the mould details.
Patent DE-2620619-A1 (DE)
Title: Module lug soldering to connecting wires - by feeding bared wire ends into eyes of fused solder blobs on lugs
Inventor: HOEH DIETRICH DIPL ING
IPC: B23K1/08
Filed: 1976-05-10
Abstract: The connecting wires are soldered automatically to the connecting lugs of electronic modules by applying in a first stage an excess of solder to the lugs. After heating the solder when in the contact position, the bared connecting wire end are moved automatically forward into the lug eyes at a speed which causes no splashes. When cool, the assembled part is moved to the next station. This accelerates the soldering operation and eliminates several individual processes. The lug eyes need not be cleared by suction and the risk of splashing tin is eliminated.
