Title: Shaft furnace for metal ore redn. - esp. iron sponge mfr. has separate concentric reaction zones
Inventor: WENZEL WERNER DR ING
IPC: C21B13/00
Filed: 1973-02-24
Abstract: In operation two zones are established axially of a shaft furnace fed at its top with ore and at its side walls transversely with reducing gases. A central zone has a charge which is less easy to reduce than the charge of a surrounding ring zone. This ensures a constant degree of redn. across the shaft furnace cross section. The central zone may be fed with a charge having a larger grain size than the ring zone charge. The centre zone charge may be of haematite ore and the ring zone charge may be of magnetite ore. The ring zone takes up about 2/3 of the cross section of the shaft furnace.

Title: Deep freeze cabinet modified for drying effect of airstream - by introducing open water reservoir between air cooler and goods display
Inventor: BROECKER FRITZ
IPC: A47F3/04
Filed: 1974-04-27
Abstract: Air circulated by a fan passes in a triple meander path first through the cooler, then back over a shallow water trough then forward again under the staging of the displayed goods containers, before passing over the goods. It then goes down, past an ultra-violet sterilizer to the fan again. Thus the circulating air is kept moist and the goods displayed do not suffer from surface drying. When it is desired to clean the cabinet, the staging can be moved up to a given position. The water used for this washing passes down through the gap and is conveniently collected in the deeper part of the water trough.

The door (11) in the side of the parallelogram is opened and four cows come through the entrance passage, and position themselves in the stalls, heads to the mangers (10), and are attached to the milking machine. The door (11) is closed, and the door (12) leading out of the third parallelogram where the cows have been fully milked, is opened. These cows leave, the door is closed and the whole unit turned through 120 deg. about its axis (2) before the cycle starts again.

Title: Core for small transformer used in toys - with lamination packets secured by taper fit and safety dowels
Inventor: KILIAN HELMUT
IPC: H01F27/245
Filed: 1974-12-09
Abstract: The core comprises a packet of U-shaped punchings (1) and a packet having a wedge shape (2). The taper of the wedge is chosen such that when the two packets are pushed together a self holding taper fit results.
