Title: Inter-rivetting of metal sheets - entails driving of rivets through sheets onto female matrix whence rivet nose expands radially
Inventor: FUHRMEISTER RALPH
IPC: B21J15/02
Filed: 1975-10-15
Abstract: Inter-rivetting of metal sheets, entails driving of rivets through the sheets onto a female matrix and the rivet hose expands radially to secure the connection. The matrix design permits its removal after nose expansion, and the process reduces prior multi-stage operations into a single operation. Rivet shafts effectively punch the rivet holes, nose enlargement is contrived by pressure against an anvil and an enlarged female matrix permits its abstraction. Pref. a matrix displacement occuring after a rivet traverses the sheets clamps the sheets against the rivet head, whence the rivet nose is expanded radially by continuing press. against the anvil, and the matris, by virtue of its enlargement is finally removed.

Patent DE-2704541-A1 (DE)
Inventor: SILBERMANN ERICH
IPC: H02G5/00
Filed: 1977-02-03
Abstract: In the case of the described busbar coupling, parallel end surfaces (15) of busbars (13) form fixed-position contact pieces. The latter can be bridged by a helical spring (5) as a moving contact link. The helical spring (5) simultaneously takes over the supply of power and ensures a suitable contact pressure. The surfaces of the turns of the helical spring (5) which is used are already tilted laterally to a certain extent in the unstressed state, and this tilting is increased when the helical spring is pushed in between the fixed-position contact pieces (13). It is thus possible to achieve a soft spring characteristic, to compensate for large tolerances and to achieve very good material filling when bridging the separating gap. The helical springs (5) can be replaced without effort and cost-effectively, as the single component which is subject to wear. Use of the described busbar coupling makes available an extraordinarily cost-effective separating element for electrical installations. <IMAGE>

Title: Tube for sepn. by centrifugation - is made of synthetic material and contains moving cylindrical separator preventing subsequent remixing
Inventor: BALLIES UWE DR MED
IPC: B01L3/14
Filed: 1977-08-02
Abstract: A tube for the sepn. by centrifuging of the heavier components from the lighter components of a liq. e.g. blood, and preventing subsequent mixing of the components, contains a cylindrical body, the density of which is between that of the components, and the external dia. of which is equal to the internal dia. of the tube. The tube is made of a synthetic material. During the centrifuging, the cylindrical body slides along the tube. The lighter component flows past it in the space formed between the body and the tube by the slight expansion of the tube, so that the body is always at the interface between the heavy and light phases. A suction piston may be attached to the cylindrical body and the tube may have a ferrule for an injection needle so that a sample can be drawn into the tube. The suction piston shaft is removed before centrifuging. Problems associated with excessive friction between glass tubes and plugs of elastomeric material, diffusion of mixt. through filter discs, and complicated methods of introducing the sample are avoided. The appts. is simple to make, e.g. by injection moulding. Mixing or diffusion of dissolved components is prevented, even during transport or prolonged storage. Filling is simpler, partic. when the appts. is used for sampling blood.
