Title: Steel mfr. in bottom blown oxygen converter - in which large amt. of solid scrap can be melted using gaseous, liq. and solid fuels
Inventor: BROTZMANN KARL DR ING
IPC: C21C5/56
Filed: 1977-07-02
Abstract: Steel is made from solid materials(a) contg. Fe, such as scrap, in a converter with tuyeres passing through the lower part of the refractory lining. Oxidant gas, e.g. O2, in a protective medium(b), is injected via the tuyeres for burning materials(c) contg. carbon, so hot gases flow up through chargena) for preheating, followed by melting and refining in the same converter. In preheating, materials(c) are pref. gases or liqs. burned in stoichiometric amts. to form CO and H2O, esp. using light or heavy fuel oil, petroleum derivs. such as residues, and/or crude tar; or CH4, C3H8, C4H10, and/or similar gases. The tuyeres pref. have an inner pipe with at least one outer pipe forming an annulus fed with liq. hydrocarbon(b). A high proportion of scrap and other solids(a) can be melted with high thermal efficiency.
Patent DE-2739106-A1 (DE)
Title: Mixing vessel for liquid-solid mixtures - with a circular mixing element fitted with scrapers
Inventor: GIUSTI RAOLO BENVENUTO
IPC: B01F7/04
Filed: 1977-08-30
Abstract: The vessel has vertical cylindrical sides and a hemispherical base and is open at the top. A drive shaft for the stirrer extends horizontally across the vessel and is driven by a motor mounted outside the vessel. The stirrer extends through a plane which includes the axis of the drive shaft and is of a shape to come in contact with the hemispherical base of the vessel. The stirrer is essentially circular and comprises two vanes. Within each vane a segment shaped piece extends across the plane of the vanes. Scrapers are fixed to the periphery of the vanes in such a way that they are capable of a certain pivoting movement. The edges of the scrapers are curved so that they conform to the inner surface of the base. A jacket may be added around the vessel base to allow cooling or heating of the contents. The vessel is partic. useful for the treatment of materials in the food, pharmaceutical and cosmetic industry. The scraping of the bottom of the vessel prevents the build-up of a sediment which could cause uneven temp. distribution. The manner of stirring prevents the breaking up of delicate solid particles.

Title: Distance and speed measuring instrument - is for track-bound vehicles and uses wheel-independent and wheel-dependent distance measuring systems
Inventor: MAYER HORST-HEINER DIPL ING
IPC: G01P1/12
Filed: 1977-09-17
Abstract: The distance and speed measuring instrument uses a correcting device in the vehicle which consists of a division circuit, a multiplication circuit and a low-pass filter. The division circuit divides the number of distance pulses delivered by a wheel-independent measuring system by the number of distance pulses delivered by a wheel-dependent measuring system. The division result is smoothed with the low-pass filter and is then multiplied by a distance increment in the multiplication circuit.

Title: Stepping drive for feeding sheet or strip to press - is achieved by oscillating brake blocks gripping brake discs
Inventor: CHRUBASIK PAUL
IPC: B21D43/09
Filed: 1977-11-14

Title: Headlamp washer control for car - has switching circuits for short cleaning pulse when lights switched on and subsequent manual selection
Inventor: ARNOLD KARL-HEINZ
IPC: B60S1/60
Filed: 1978-12-14
Abstract: A headlamp washer control has high pressure fluid jets to clean the lenses without wipers. The washers are only operative when the lights are switched on and operate for only short pulses. A switch provides manual selection of the cleaning pulses, with a multivibrator (34) and a monostable vibrator (25) providing two short jet pulses every time the switch is operated. The system provides the short pulses no matter how long the switch is operated. This saves fluid, without affecting the cleaning action unduly. The vibrator circuits are provided on simple integrated circuit chips and are readily included in the waher pump circuit.

Title: Compact conductor end=to=end coupler - has contact sleeve with U=shaped wire clip engaging conductor groove
Inventor: BUSCH WOLFGANG DIPL ING
IPC: H02B11/04
Filed: 1979-02-13
