Title: Arrangement for frictional fastening
Inventor: BRANDENSTEIN MANFRED
IPC: B23P11/00
Filed: 1988-03-12
Abstract: To fasten a bolt 5 in the hole 2 of a sheet-metal part 1 by pressing it into place, a zinc layer 4 is provided on the hole surface 11. The bolt 5 has a tapered edge reduction 6 at the free end. The tapered edge reduction 6 causes considerable compression of the zinc material 14 in the recesses 12, caused by geometrical inaccuracy, at the contact surfaces 9, 11 and conveys excess zinc material 15 out of the hole 2. An annular groove 7 made in the circumferential surface 9 at a distance from the tapered edge reduction 6 and having sharp edges 19 scrapes further zinc material 15 with the aim of achieving an ideal cylindrical shape of the hole surface 11 and produces in the area of the recesses 12 a radial surface pressure adapted to the neighbouring zones. Further strengthening of the seating is achieved by cold-welding effects when the bolt 5 is pressed into place and in the area of the zinc sections 12, 13. <IMAGE>

Patent DE-3903170-A1 (DE)
Title: Storage rack with detachable clamped connection
Inventor: WEIGL GERHARD
IPC: A47B57/52
Filed: 1989-02-03
Abstract: Until now, for this application predominantly screwed connections have been used, and hung-in components, which have disadvantages, have also been used. The clamped connection presented here is possible on commercially available I-sections. The simple handling consists in the fact that the horizontal component (1) is pushed over the vertical component (2) without lifting, tilting or turning and both parts are locked by the pin (3). As a result of the inclined position of the holes (4) and (5), a clamping action between (1) and (2) is obtained, which, in the event of loading of (1), is even increased and leads to further frictional locking. In order to prevent the pin (3) from bending under heavy loads on (1), two-piece wedges are inserted between (2) and (3). <IMAGE>

Patent DE-3912612-A1 (DE)
Inventor: HORVATH LAJOS
IPC: B01J47/10
Filed: 1989-04-17
Abstract: The invention concerns a process and apparatus for the countercurrent contacting of solid materials with liquids in which an amount of liquid less than that required for ensuring the minimum rate of fluidisation, is caused to flow from below upwardly through a bed of a particulate solid which is either continuously or intermittently fed and discharged. The liquid flow is of varying direction and/or 'broken down' into pulses. The maximum velocity of the upwardly flowing liquid from time to time exceeds the minimum fluidisation velocity. The liquid is finally discharged by overflow 20 above the bed. The solid is charged at the top of vessel 1 and discharged from its bottom. The liquid is added at 6 into auxiliary vessel 4 and the pulses are provided by air under pressure supplied via valve 9a and relieved via valve 9b. Throttles 22, 23 govern the rate of air flow, and hence the shape of the pulse. <IMAGE>
