Patent DE-2345034-A1 (DE)
Title: Manufacture of multi-track magnetic heads - head surface is finished off with precision machine tool using diamond cutters
Inventor: WALDKIRCHER FERDINAND
IPC: G11B5/187
Filed: 1973-09-06
Abstract: The finished facing of the head of a magnetic head, particularly the type used in multi-track players, needs to have a particularly smooth surface and a predetermined profile e.g. cylindrical section. Fine finishing of the head surface is achieved by the present process on a precision machine tool with linear working stroke by means of diamond cutting tools. Pref. the machine tool has a holder in which four diamond tools with overlapping cutters can be set. The desired form for optimum reproduction is assured by four diamond cutting angles overlapping each other. The given best angle of tension is held and the pressure of cutting is reduced to a minimum so that influences on the magnetic qualities of the core material are also minimal and requires only a small expenditure of time to carry out the cutting process is required.

Patent DE-2408242-A1 (DE)
Title: Beer filling procedure in bottling factory - involves introducing small amount into empty bottle and allowing it to foam
Inventor: PETERSEN HEINZ
IPC: B67C3/26
Filed: 1974-02-21
Abstract: Filling beer and other frothy drinks requires a small amount of beer to be filled into the container before this has been pressurised for the filling operation. The relaxation of pressure which the beer immediately undergoes causes it to foam, and it is at this point that the genuine filling operation commences. The container is pressurised with air and then is filled so as in this way to avoid any direct contact between the air and the beer being filled. This has a pronounced effect on the taste of the beer, undiluted as it now is by the air which otherwise inevitably gains access to the container during filling. The foam drives this contaminating air out of the bottle.

Title: Convertible bed settees for single and double beds - using frames with concealed adjustment mechanisms, leaving no gaps
Inventor: GREINER OTTO
IPC: A47C20/04
Filed: 1974-03-04
Abstract: The box bed or double bed is designed so that the seat and back sections are connected together by hinges so that they can be raised and lowered by the pressure of the user and in the case of a box bed the side parts of the box are recessed so that the larger upper part of the crossbeams of the back section rests on the upper edges of the side parts. This means that when changing into the sitting position there is room for the lower sections of the crossbeams and for the seat section as they drop down. In the case of a double bed a board is attached to the centre of the top part of the bedstead so that the lower edge of the board rests on the transverse support and protrudes slightly so that the adjustment mechanisms can be attached on each side. The size of the front end of the board is such that when the back sections of the bedstead are raised they are not obstructred by the lower parts and seat parts which drop down.

Inventor: HOELZEL KLAUS
IPC: B29B17/00
Filed: 1974-05-28
Abstract: Waste accumulating in carpet mfr. is recovered/re-used by comminuting it to give a flowable matl.; adding stabilisers, seeding agents, metal soaps and pigments; charging to an extruder to de-gassing; and granulating so as to obtain thermoplastics malt. suitable for injection-moulding.

Title: Blast furnace slag spout made from water-cooled metal pipe - so layer of solidified slag acts as spout lining
Inventor: BLOCK F R DR RER NAT
IPC: C21B7/14
Filed: 1974-06-10
Abstract: Blast-furnace slag spout or furnace spout is preformed from metal parts and water-cooled using an outer channel formed by either placing a pipe round the spout or using a second external wall, i.e. so the water flows through the resulting annular channel, thereby causing a covering layer of slag to form which functions as the actual slag spout or runner. The metal spout is pref. made of several overlapping metal parts and cooling may also be achieved using air. A tunnel for exhaust gas may also be located over the spout to reduce heat losses. Eliminates the time and cost involved in making a new spout or runner from sand after each tapping operation. Working conditions are improved.

Title: Disc damper for tracked vehicles - with interspaced moving and fixed friction discs in staggered coupling to damper
Inventor: ZENZ WILHELM
IPC: B62D55/112
Filed: 1974-10-19
Abstract: The friction absorbing bearing of the tracked vehicle has inner (5) and outer shells (1) which rotate relative to each other as the suspension moves. The outer surface of the inner shell, and the inner surface of the outer shell are provided with keyways parallel to the axes of the shells. The keyways serve to locate friction discs with alternate discs coupled to the inner shell, and the remainder to the outer shell. The relative movement of the shells causes the friction discs to rub over each other to absorb the suspension forces. The coupling to the keyways is arranged in a staggered manner so that progressive movement of the bearing brings progressively more friction discs into effect.
