Title: Continuous lubrication of extrusion dies - pref. using ring groove in die inlet so lubricant flows onto billet
Inventor: WAGNER ALFRED
IPC: B21C23/32
Filed: 1976-01-23
Abstract: The working surface of an extrusion die are continuously lubricated, the novelty being that the surface of the blank is locally lifted from the working surface to form a dead zone into which the lubricant is fed. The lubricant then flows onto the surface of the blank, and onto the working surface of the die, and is carried through the die. The pref. device employs >=1 projection and >=1 channel to feed a liq. or pasty lubricant onto the blank, esp. using a ring channel at the die inlet. Alternatively, several sickle-shaped projections may be used contg. holes leading to the working surface of the die. When a ring channel is used, it is pref. formed by an inner- and an outer- ring at the die inlet. The lubricant can be supplied without using very high pressures similar to the extrusion pressure, and extrusion speeds are increased, e.g. with Al alloys.

Title: Briquetting sponge iron dust for steel mfr. - where dust is mixed with aq. emulsion of bitumen binder
Inventor: AUSTIN LAWRENCE J DR
IPC: C21B13/00
Filed: 1976-04-03
Abstract: The water in an aq. bitumen, emulsion does not react with the iron dust, because the bitumen and/or the emulsifier apparently covers the surface of the dust and makes it inactive, even when the emulsion contains up to 75% water. In an example a hard, high vacuum bitumen, softening point R + B = 85-95 degrees C., is used in an aq. emulsion contg. 25 wt.% of the bitumen. 6 wt.% of the emulsion is used with the iron dust which therefore contains 1.5 wt.% of the bitumen. The briquettes obtd. met the required compression strength of 150 kp. Due to the low amt. of bitumen used, the briquettes only contained 0.09% sulphur.
Patent DE-2615938-A1 (DE)
Title: Gas-permeable plugs put in vents of mould for foamed plastic - are of cigarette-filter or sponge material
Inventor: BISCHLIPP KLAUS
IPC: B29C33/10
Filed: 1976-04-12
Abstract: The gas permeable plugs readily permit the escape of air or other gases from the mould during foaming but at the same time are not permeable to the plastics itself. This avoids the need to close the vents at some ill-definable time during the moulding process. The filters are pref. of cigarette filter material or of sponge. The moulds are partic. long, narrow moulds, such as are used for making door - and window-frames; the filtered vent is put in the small end-plate of such a mould.

Title: Article packed in rigid box with plastics foam spacers - formed by plastics foamed into flexible bags surrounding article
Inventor: OERTEL ALEXANDER
IPC: B65D81/32
Filed: 1976-10-29
Abstract: Packing articles in containers, esp. rigid boxes for transportation, consists of filling the space around the article inside the box with a plastic foam. The plastic material is foamed inside >=1 flexible bags and these bags are then packed into the space around the article to fill the box. There is no direct handling of the foam plastics, which is extremely difficult on account of its stickiness. Where the article to be placed in the box has a tendency to adhere to the foam, this eliminates the necessity for previously wrapping the article i.e. double packaging operation is eliminated. As a result the entire foam surround is produced much more easily.
