Patent number: 4798315Abstract: In a casting nozzle, tubes are placed between a bar-shaped mouthpiece and a distribution bar, which connect holes in the mouthpiece and the distribution bar to allow for the flow of the melt. Pulling rods which are under tension, are anchored to the mouthpiece and to the distribution bar and press these parts elastically against the ends of the tubes in such a manner that the nozzle components are elastically braced, yet remain flexible and can adjust freely to heat dilatations or inaccuracies which occur in fabrication or assembly. The nozzle components, particularly the tubes, are easy to obtain and to exchange. Due to the fact that the pulling rods enter the mouthpiece from its back side and are anchored therein, the mouthpiece can be very slender, thus allowing for thin casting.Type: GrantFiled: April 23, 1987Date of Patent: January 17, 1989Assignee: Larex AGInventor: Wilhelm F. Lauener

Patent number: 4795249Abstract: The contact lens comprises a central optical zone and a peripheral zone for fastening the lens. For centering said lens the peripheral zone comprises two stabilizing bosses which are disposed on the horizontal stabilization axis of the lens. For large palpebral openings it may be preferable to use two pairs of bosses, whereby each pair comprises two bosses, disposed symmetrically to said axis of stabilization. For multifocal corrections it is possible to use a third boss, disposed on the vertical axis of the lens. These stabilizers allow a perfect centering of the lens, hindering its rotation and the use of very thin lenses.Type: GrantFiled: August 28, 1987Date of Patent: January 3, 1989Assignee: Gerard MullerInventor: Gerard Muller

Patent number: 4789315Abstract: The machine comprises two plate-like supports (9, 12) each provided with a crown of displacement blades (10), respectively displacement chambers (11), engaged into each other, and displaceable into a relative circular translation motion. The drive is implemented by a gear (7-9) at the center of the supports (9, 12), which exerts a force (F.sub.N) on one of the supports (9) at a radially displaceable position, said force presenting a radial component (F.sub.R) and a tangential component (F.sub.T). The direction of the force and the arrangement of the chambers (11) are so selected as to provide for a predetermined static position of the blades (10) in the chambers (11) independently of the wear. Optimum operation conditions are thus obtained with simple design and fabrication. For producing said pump, the plate-like supports are lapped pair-wise when they are in the state of blanks in conditions similar to the operation conditions and are then mounted in the machine.Type: GrantFiled: December 1, 1986Date of Patent: December 6, 1988Assignee: Gutag Innovations AGInventor: Kurt Guettinger

Patent number: 4785873Abstract: Prior to reaching the nozzle's exit, the belt is pressed from outward against the nozzle by means of a rail supported by springs whereby the mould is reliably sealed off under all working conditions. Pressing the belt against the nozzle can also be achieved by means of pistons or the direct hydrostatic and/or hydrodynamic effect of the coolant from the outside or through various combined measures. In order to reduce friction and wear, the nozzle in the area of contact with one belt can be provided with a wear-resistant coating or wear-resistant inserts. This sealing method enables a casting process with high metallostatic pressure, consequently resulting in a high quality product.Type: GrantFiled: February 26, 1987Date of Patent: November 22, 1988Assignee: Larex AGInventor: Wilhelm F. Lauener

Patent number: 4785543Abstract: The ring-shaped sighting device comprises an annular ring-shaped space the axial height of which decreasing from a window provided in the annular space for observing the level of the liquid to the opposite side. Hence, the uneven bottom forms a displacer for the liquid present in the annular space, so that the volume of this liquid versus its surface can be maintained of a low value on the entire periphery of the annular space. In this way, thermal dilatation of the liquid has no significant importance on the level of the liquid which guarantees an indication largely independent of the temperature.Type: GrantFiled: July 28, 1987Date of Patent: November 22, 1988Assignee: Eidgenossische WaffenfabrikInventor: Weber Hans

Patent number: 4782640Abstract: A structural assembly includes a square trough-shaped stone having inclined external corner regions and a dovetailed groove formed in each wall side. The dovetail tongue of a connecting plate fits into the dovetailed groove. At the lower end of the internal surface of each wall of the stone, a shoulder portion may be provided for accommodating base elements. The height of the connecting plate is advantageously greater than the height of the trough-shaped stone, so that the plate projects beyond the stone in a vertical direction for connection to further stones.With such an assembly, it is possible to erect dry-stone type walls of various types. The individual elements of the assembly can be produced rationally and economically, and it is also possible to produce end elements and corner elements from the trough-shaped stones by cleaving the stones along grooves provided for such purpose.Type: GrantFiled: September 10, 1986Date of Patent: November 8, 1988Inventor: Rolf Scheiwiller

Patent number: 4780583Abstract: An electrical switch suitable for a miniature apparatus such as a wristwatch comprises a resilient contact plate which is mounted on a member capable of rotating about an axis. The contact plate has two arms which extend radially from a rigid or mounted central portion. The outer ends of the arms are supported on a contact member, the arms being elastically deformed by the action of the contact forces. The two arms have different lengths and they are weakened in a different manner by apertures at their mounting location. Consequently, it is possible to achieve ideal compensation for the couples produced by the contact forces. In addition, an ideal deformation of the arms of the contact plate is obtained, as well as a well-defined position for the bearing points of the contacts.Type: GrantFiled: October 3, 1986Date of Patent: October 25, 1988Assignee: Paolo SpadiniInventor: Norbert Perucchi

Patent number: 4775358Abstract: In a multi-bobbin machine for making paper booklets e.g. of interleaved cigarette paper, a multiplicity of strips from respective supply bobbins are interfolded and converged to form a booklet strand which is cut to length by a cutting station which reciprocates along the strand so that booklet lengths enter it and are cut. A rotating non-circular shaft passes through the cutting station and a sleeve in the cutting station slides axially along the shaft as the station reciprocates and rotates with the shaft. The sleeve is independently linked to a strand clamp and to a cutting knife which are separately timed and move along different paths, the strand clamp moving longitudinally towards and away from the strand while the knife makes a slicing movement across and through the strand.Type: GrantFiled: March 10, 1987Date of Patent: October 4, 1988Assignee: Rizla LimitedInventor: Stanley G.

Patent number: 4773468Abstract: Rods are placed into axially arranged grooves of the roll core. These rods protrude radially from the roll surface and the roll shell is shrink-fitted onto the rods. Due to the creeping movement of the roll shell which is a result of periodical heating and cooling thereof, the inside surface of the shell and the interfacing outside surface of each rod are subject to wear. Whenever this wear has proceeded beyond a tolerable limit the rods are replaced, whereafter a new shell with a normal inside diameter is again shrink-fitted onto the rods. Thereby the rod's and the shell's dimensions must never be changed. The roll core is not subject to wear. Stock-keeping and fabrication are particularly simplified due to the fact that the dimensions of the replacement parts never change.Type: GrantFiled: May 11, 1987Date of Patent: September 27, 1988Assignee: Larex AGInventor: Wilhelm F. Lauener
