Patent DE-4137547-A1 (DE)
Title: Continuous furnace of reduced cost - has reduced or eliminated holding section for sepd. slabs
Inventor: BATHELT JUERGEN DR
IPC: C21D9/46
Filed: 1991-11-12
Abstract: The continuous furnace, to heat thin slabs, has at least two parallel sections to take separated slabs from two cast strands and a moving section to shift the slab into a holding section for rolling. The length of the shortened holding section (4) is smalller than the max. length of the slab (5) on the moving section (2) moving across the line of travel through the furnace sections. The reduced holding section (4) can be of a 0.00mm length, for elimination, so that the continuous furnace is composed only of sections to take the incoming sepd. slabs and the section to move the slabs (5) across the longitudinal direction of travel through the furnace. The total length of the furnace can be reduced by about 14%, with an increased speed through the furnace of about 20% and a reduction in the travelling time of the moving section (2) of about 4%. ADVANTAGE - The structured furnace sections give a reduced cost of the furnace.

Title: Cheese rind removal appts. - has cutter with linkage positioning to take set thickness from prod. surface to cut rind clear without cheese wastage
Inventor: KAUL DIETER ALBERT DIPL ING
IPC: A01J27/00
Filed: 1991-11-26
Abstract: The assembly to remove rind from cheese, with a cutting tool (1) and a linked and sprung cutting head (2) with controlled pressure, has a powered cutting shaft (11) in a housing (10) positioned by an adjustable distance plate (12) to pass along the product to take a given layer from the product surface, according to the set gap (12a). The prod. is moved parallel to the ring cutting tool to give an even material removal from the prod. surface, or the tool moves in parallel over the prod. Two forces (F1,F2) are applied to the centre axis of the cutter (M1), seen longitudinally, on the cutter housing (10) through transmission plates (13). The forces are transmitted from pressure-controlled pneumatic cylinders (14,15) through linkages (14a,15a) on a suspension mounting (3) to give reserve movement to compensate for variable prod. thicknesses. The forces (F1,F2) are structured to give a suitable low cutting head (2) pressure against the prod. and, on an even pressure, the cutting head (2) can follow the prod. contour with movement through the piston rods of the two cylinders (14,15). As the forces are transmitted through linkages (14a,15a), the cutting head (2) can be angled against the side contours of the prod. for an even removal of the rind all round it. ADVANTAGE - For cheese of all sizes and shapes with a rapid and effective rind removal action, with no waste of the cheese material.

Title: Infusion system which maintains constant volume flow - has spring arranged between holder and fluid container which, as fluid runs out of container, relaxes and fluid level is kept at constant height
Inventor: WEINHOLD WOLFGANG P DIPL ING
IPC: A61M5/168
Filed: 1992-04-23
Abstract: An elastic spring element (7) is arranged between the holder (6) and the fluid container (2) and is kept in a metastable condition. As the fluid runs out of the container, the spring becomes shorter and thus keeps fluid level in the container at a constant height. Alternatively, thr container can be directly attached to the holder, the holder being attached to the stand by a bearing. The spring in this case is compressed between the holder arm and a fixed part of the stand. As the fluid runs out, the spring relaxes and the fluid level is kept at a constant height. USE/ADVANTAGE - For use in hospitals, nursing homes etc. Provides constant control of the volume flow rate and thus repeated checks are not necessary.

Title: Guide key for automatic adjustment of gap between two parts - moves against given friction force to achieve setting of part in gap during first closure
Inventor: MEYER DIETER
IPC: B62D25/12
Filed: 1992-08-10
Abstract: A specific application relates to the gap between the bonnet and wing region of a car body. Fixed to the inside skin of the bonnet (1) is a self-adjusting guide key (4) bridging the gap (3) and bearing against an abutment surface (6) with a predetermined force. Attached to the face of the guide key and running parallel to the gap is an elastic pad (7) having a lower face (8) which is inclined to the closing direction of the bonnet. Thus as the bonnet approaches closure the face (8) first contacts the abutment surface (6), pushing the guide key to the right. The resisting force exerted by the guide key is determined by the adjustment of screw (11) which clamps a sawtooth serrated surface of the key against a corresponding serrated surface of the fastening plate (9). First closure of the bonnet provides the setting for the guide key, which can then be locked in placed by further tightening of the screw (11). ADVANTAGE - Provides optimum closing conditions. Simple, mass produced parts.
