Patent CH-687694-A5 (CH)
Inventor: NUSSBAUMER BENNO
IPC: B65D39/00
Filed: 1993-06-18
Abstract: The composite totally synthetic plug (stopper) for wine bottles and drinks bottles of the same generic category is intended to help compensate for the shortage of qualitatively perfect natural cork. The plug is formed by a base body (1) made of plastic. Arranged on the top or bottom face (6, 7) or inside the base body (1) is a barrier layer (2) made of microfilter laminate which is impervious to liquid and greatly inhibits the passage of gas. Supplying and discharging gas ducts (5) with a variable cross-sectional area are caused to open out on the surface of the barrier layer (2), and thus a desired gas exchange between the bottle interior and the outer atmosphere can take place. The invention is based on the principle of metering an intentional gas exchange by using barrier layers (2) with different permeability or else changing the cross-sectional area at the barrier layer (2), through which the gas exchange is channelled. The barrier layer (2) may have a disc- or rod-shaped, also wedge- or cone-like form. To facilitate attachment of a corkscrew (10), a corkscrew bore (4) with a helical groove (11) is provided, in which case the gas duct (5) and the corkscrew bore (4) can merge into one another. <IMAGE>

Title: Method and device for removing a loose-fitting rivet from the rivet hole
Inventor: BREU HANSPETER
IPC: B21J15/50
Filed: 1982-04-05
Abstract: Sharp teeth are arranged in the form of a ring as adhesive means (2) on one end of a tubular drill guide (1). The drill guide (1) is inserted through a hole of a handle (3) and is clamped there by means of a screw (4). The adhesive means (2) or the sharp teeth are pressed onto the rivet head (5) by hand via the drill guide (1) and the handle (3), so that the rivet cannot co-rotate during the drilling. The drill (6) is then guided through the drill guide (1) up against the centre of the rivet head, and a hole reaching as far as the rivet shank is drilled in the rivet head (5). The rivet shank can then be pushed out of the rivet hole. A new rivet, expediently a pop blind rivet or Chobert blind rivet, is then fitted in the rivet hole which has remained undamaged. <IMAGE>
Patent CH-670076-A5 (CH)
Inventor: HUNZIKER WERNER
IPC: B24C3/10
Filed: 1985-06-19
Abstract: Apparatus for deburring or other surface treatment of workpieces has a tubular housing with a set of axially parallel flexible, elastic or rigid rod- or wire-like components which define gaps and whose end portions are separately affixed to driven rotary end walls. The end walls wobble in synchronism with one another so as to move the components longitudinally while the components orbit about the axis of the receptacle. The workpieces which are admitted into one end of the receptacle are agitated and rotated as a result of rotation of the receptacle and move toward the other end of the receptacle due to reciprocation of components in parallelism with the axis of the receptacle. One or more nozzles admit jets of flames, solid, liquid and/or gaseous media which penetrate through the gaps between the components of the receptacle and treat the workpieces.

Title: Spaced disc magnetic gearing - has magnetic peripheral poles with pitch different for respective discs for non uniform angular velocity
IPC: F16H13/12
Filed: 1973-11-27
Abstract: The magnetic gearing comprises two discs (1, 2) each having around its periphery a succession of alternately positive and negative magnetic regions (N, S). The discs are supported for rotation with their peripheries slightly spaced apart. As one disc rotates its magnetic regions attract the opposite poles of the other disc and cause it to rotate. The pitch (t1) of the poles of the one disc is different from that (t2) of the other disc. This makes it possible to impart to the driven disc a predetermined non-uniform angular velocity. Natural or electromagnets may be used. For natural magnetization the discs may be of a platinum-cobalt alloy.
