Title: Process and follow-on tool arrangement for the production of a slotted plate, in particular a selector gate plate for motor-vehicle gear boxes
Inventor: KELLER MANFRED
IPC: F16H61/24
Filed: 1985-07-23
Granted: 1986-12-11
Abstract: The invention proposes a process for the production of a slotted plate, in particular a selector gate plate, in which, starting from a strip of material, both those gate slots which have vertical boundary walls and those with oblique boundary walls are cut in successive work stages by fine blanking, the strip of material being divided into uniform segments by means of separating cuts, although the segments remain connected to one another by deformable residual webs. In the individual work stages, the segments are clamped in a horizontal or oblique position before the respective fine blanking operation, depending on the alignment of the boundary wall surfaces of the gate slots to be cut, the residual webs adjoining the segment in question being deformed several times in an essentially plastic manner. In this way, it is possible to achieve even complex gate-slot configurations at an economical price by fine blanking. A suitable follow-on tool arrangement is indicated for carrying out the process.

Title: Quick-action closure screw system
Inventor: JUERGEN NORD KLAUS
IPC: F16B35/04
Filed: 1985-09-05
Granted: 1987-05-07
Abstract: A quick-action closure screw system in order significantly to shorten the time-consuming screwing-in process. A system is proposed here which, by means of a variable screw area and variable threaded jaws, ensures that the screw and nut can be pushed over one another without any significant loss of strength. It is always possible to use each part independently as a screw or nut. The advantages which occur in the case of this system are a reduced labour cost, and overtightening of the respective element is also prevented.
Patent DE-3642032-C1 (DE)
Title: Lathe for the machining of workpieces which tend to sag
Inventor: STRATE HANS
IPC: B23Q1/76
Filed: 1986-12-09
Granted: 1988-05-11
Abstract: Accurate machining of rolls which are clamped in between a headstock and a tailstock of a lathe is not possible with the required degree of precision if the rolls, owing to their dead weight or owing to an unfavourable ratio of diameter to length, tend to sag, thus causing the axis line to diverge from the horizontal. These disadvantages are avoided in that the roll is subjected to a tensile force acting in the axial direction. By virtue of the resulting tensile stressing, the sagging of the roll is counteracted.
Patent DE-3722022-C1 (DE)

Title: Overburden drilling device
Inventor: KLEMM GUENTER DR-ING
IPC: B25D17/16
Filed: 1987-08-25
Granted: 1988-09-15
Abstract: In an overburden drilling device, flushing medium is fed through a flushing pipe (26) to the inner pipe string (11). The flushing pipe (26) runs through a bore (27) in the hammer piston (17) of the hammer drill. A rotary drive (14) rotates the drill strings (10, 11), which are connected to the shank end (13) projecting into the rotary drive (14). The flushing medium is directed through the flushing pipe (26) into the shank end (23) and from there into the inner pipe string (11). The outside diameter of the flushing pipe (26) is less than the inside diameter of the bore (27) in the hammer piston (17) and of the flushing bore (23). The sealing between flushing pipe (26) and flushing bore (23) is effected by a widened head piece (33) at the end of the flushing pipe. The head piece (33) contains a seal which passes along the cylindrical flushing bore wall when the hammer piston (17) performs blows on the shank end (13). An annular space (35) at the head (33) forms a choke point in order to reduce pressure surges which act on the seal. <IMAGE>

Title: Merchandise stand for plate- or card-shaped objects
IPC: A47F5/11
Filed: 1988-07-14
Granted: 1990-01-11
Abstract: The invention relates to a merchandise stand (1) for plate- or card-shaped objects, in particular a display of a sales stand for blister packs with a card-shaped backing (21), the merchandise stand (1) having holding slots (2) for inserting the plate- or card-shaped objects. In this arrangement, at least two material plies (4a, 4b) are arranged one above the other in the region of the holding slots (2) of the merchandise stand (1) and in each case one slot edge (5a, 5b) of a holding slot (2) is provided in one of the material plies (4a, 4b) and the other slot edge (5a, 5b) is provided in the other material ply (4a, 4b), respectively. These slot edges (5a, 5b) are formed by approximately slot-shaped cutouts in the material plies (4a, 4b), which are arranged offset from one another in such a way that the neighbouring edges of the cutouts of material plies (4a, 4b) lying one above the other form the edges (5a, 5b) of the holding slots (2). As a result of this offset of the cutouts, it is possible to produce holding slots (2) whose slot width even approaches approximately zero. Such a slot width cannot be produced, in practice, with simple punched-out areas or in deep-drawn plastic parts (see Fig. 3). <IMAGE>

Title: Chain-coupling element with fixing point
IPC: F16G15/00
Filed: 1988-10-05
Granted: 1990-03-08
Abstract: In order to connect the individual lengths (3) of rubbish chutes, use has been made, up until now, of load-bearing chains which exhibited in each case a carbine hook and a fastening eyelet at their free ends. Consequently, the production of the load-bearing chains is complicated and expensive. By using a chain-coupling element having an upper, open retaining eyelet (7), for receiving a free chain link (9) of the upper chain, and a lower hook finger (8) for receiving the free chain link (11) of a lower chain, which is fastened in the upper region on the wall (2) of the length (3) of the chute, the load-bearing chains can be designed as simple chain pieces. The opening width (13) of the retaining eyelet (7) is of a smaller dimension than the chain-link thickness, with the result that the free chain link (9) is secured after having been inserted. A securing clip (4), subjected to prestressing, secures the lower chain link (11) against falling out unintentionally. <IMAGE>
