Title: Cold-track pick-up device in continuous casting - with combined cable hoist and drive for controlled feed-rate
Inventor: HOFFMANN RUDOLF
IPC: B22D11/08
Filed: 1973-04-11
Abstract: A device for lifting a chain-type cold-track, on a continuous casting plant, where the track, after leaving the sec. cooling area, is lifted off a roler conveyor by a cable-hoist and deposited on a horizontal track on the casting platform so that it is ready for the next casting operation. The result is safer working conditions and the need for a crane is eliminated. A hook, attached to a pair of cables is positioned at the end of the bottom roller-conveyor along which the cold-track travels. The hook engages the front end of the cold-track and lifts it vertically then pulls it round a curve onto the horizontal track on the casting platform, after which it can be driven down into the mould at a controlled rate, the cable acting as a break. The hook is designed to engage the track with no mechanical assistance.

Title: Carburizing and core hardening of steels - using a continuous belt furnace supplied with pressurized gas
Inventor: KIEFERLE WOLFGANG
IPC: C21D1/74
Filed: 1974-12-05
Abstract: A process is claimed whereby steels may be carburised and quenched to give surface and/or core hardening in a single appts. The work is placed on a continuous belt which passes first through a furnace. Purified air and gas (pref. propane) are heated by heating coils to 1120-1140 degrees C and passed under pressure through ducts to emerge through several orifices very close to the work. The work is therefore subjected to high carbon potentials giving efficient carburization. The belt then carries the work into a cooling zone, up to twice as long as the furnace, which is also filled with furnace gas. This cools the work under controlled conditions to give surface and/or core hardening. It then needs no further heat treatment. Steels can be treated cheaply and continuously in one appts. Higher surface hardnesses can be obtd. than with conventional processes.

Title: Alkali aluminosilicates used as builders in detergent compsns - treated with pentaerythritol to improve wettability
Inventor: REOBKE WOLFGANG DIPL CHEM DR
IPC: C11D3/12
Filed: 1975-03-12
Abstract: Surface of ion-exchanging crystalline alkali aluminosilicates used as builders in washing, cleaning and rinsing compsns. is rendered hydrophilic by mixing the alkali aluminosilicate with up to 30 wt. % of pentaerythritol, drying and grinding. The pentaerythritol can be introduced in the form of an aq. soln. Suitable alkali aluminosilicates are zeolites of the A, X and Y types; the alkali can be Na, K or Li. Alkali aluminosilicates are capable of exchanging the alkali ions for Ca2+ and Mg2+ thus exerting a water-softening effect. They can be used for this purpose in washing, cleaning and rinsing compsns. instead of the objectionable phosphates, under the condition that their wettability is improved by a surface treatment such as described above (otherwise their action is too slow, esp. for use in washing machines, and they tend to form encrustations on the walls of the washing vessel at the air-liquid boundary).
