Title: Ball or tube mill - has grid-like lining for increased wear resistance in grinding vessel
Inventor: DEMEL GERHARD
IPC: B02C17/14
Filed: 1974-04-30
Abstract: Ball or tube mill comprises, in the grinding vessel, a wear lining with screen-like or grid-like openings disposed adjacent to the vessel wall or spaced from it, with no material outlet between the lining and vessel wall. This allows the grinding products to penetrate through the openings and into the space between lining and wall and block them, protecting the lining from wear in the region of the openings. Alternatively the openings may be smaller than the abrasive bodies, so that the spaced between lining and wall and/or the openings can only become blocked with ground material, and the abrasive bodies in the region of the openings can only come into contact with the material to be ground.

Title: Folded boxes prodn. of synthetic crease resistant film - from blanks pressed by punch and die, ready for welding
Inventor: ORDOWSKI EUGEN
IPC: B65D5/02
Filed: 1975-09-22
Abstract: Folded boxes are produced with a closed bottom formed by flaps extending inwards from the box sides. When flat film is used a blank is stamped out to form e.g. the four sides of a rectangular box with four alaps overlapping each other to fill in the bottom and having well-defined creases to the corners between sides and bottom. This is welded into a rectangular section and held in a frame by vacuum while the flaps are folded using a tool with a series of inclined flutes, semicircular in section, on its upper surface, which turn the projecting edges of the flaps inwards, upwards and against the sides of the frame, giving them a permanent pleat. The inclined flute contacts one corner of the flag first and extends its action across the full width. The pleat similarly is effected gradually as the tool lifts, and its inclined edges close the gap and press the flap against the box sides and the frame. Eliminates the band work previously necessary.

Title: Resistance root welding process for tube ends - of copper and aluminium alloys, giving uniform penetration by use of chloride flux and direct current, negative pole
Inventor: SCHLEMPER HANS
IPC: B23K11/18
Filed: 1976-06-24
Abstract: Resistance root welding process with protective gas for joining tube ends of Al and Cu alloys, such that the tube ends to be joined together, after preparation without bevelling, are coated with a predominantly chloride-contg. flux, then butted together without an air gap and welded by D.C. negative pole with bare electrodes. Used in mfr. of condensers and economisers. Lower heat input gives uniform penetration and improved joint properties. Chloride flux removes oxide and allows use of D.C. negative welding instead of A.C., lowering heat input to the joint. Smooth end faces of the tubes are coated with flux, pressed together and brought into concentricity and welded to give uniform and clean penetration, not requiring further treatment.
Patent DE-2628858-A1 (DE)
Title: Sausage fillings prepn. - with addn. of water contg. carbonic acid to the mincing stage
IPC: A23L13/60
Filed: 1976-06-26
Abstract: In the prodn. of sausage fillings, a metered amt. of water contg. carbonic acid is added to the material before or during the mincing stage. Pref. the water contains 8-14 g carbonic acid/l. The CO2 may be fed into the water feed line e.g. from a CO2 bottle, using a suitable mixing device. The addn. of water improves the binding properties of the meat, while the CO2 overcomes discolouration of the prod. due to oxidn. and also has a bacteriostatic effect. This eliminates the need for additional acidification agents, sugars and binders so that the meat has an improved flavour, red colour and keeping properties. Over pacification of the prod. is prevented by the limited solubility of CO2 in the water feed.

Title: Rotating cylinder lock with flat tumbler components - has split flat tumblers with inclined faces for sliding and rotating
Inventor: HANHS KARL DIPL ING
IPC: E05B29/00
Filed: 1976-09-10
Abstract: The rotating cylinder lock has simplified tumbler system in which the number of tumbler elements used is reduced. The tumbler spring has a strength such that the tumblers are in close contact with their guides and they are still able to slide in greased and dusty condition. The tumblers cannot be sensed for unauthorised opening. The tumblers slide on each other by their contacting flat faces and the flat tumblers are arranged at angle to the cylinder rotating direction. The tumblers project in a guide gap, under spring force, from the housing up to the key channel. Each tumbler consists of two plate halves with preferably sloping dividing lines. Hence the tumblers are moved along straight line in guide gap and they also rotate.
