  • Publication number: 20080207042
    Abstract: An electrical connector is described which comprises a first unit, a second unit, each unit bearing an electrical contact, the first unit comprising a protruding portion (103), the second unit comprising a receiving portion (102), wherein both the protruding portion and the receiving portion have substantially planar matching shapes, the protruding portion is arranged to be insertable into the receiving portion along an axis substantially perpendicular to each substantially planar matching shape, and the protruding portion and the receiving portion are arranged to be rotatable relative to each other about the axis thereby bringing the electrical contacts into alignment. The connector is particularly suitable for use in wearable electronics and solves the problem of how to arrange a connector which is easy to connect up, particularly by the old or infirm.

  • Patent number: 6574992
    Abstract: During a process for bending and quenching a window pane, the latter is bent to the desired shape using a forming frame. Next, by means of this same forming frame, the entire surface of both sides of the bent window pane is rapidly cooled, in a quenching station which follows the bending station, by blowing cold air using blowing boxes provided with blowing nozzles. While the entire surface is being rapidly cooled, the edge regions of the window pane which rest on the forming frame are subjected to a blast of additional cold air by the suitable supply of compressed air to the openings passing through the forming frame.

  • Patent number: 6318125
    Abstract: A process for shaping glass sheets with a surface-shaping mould, against which the glass sheets are pressed using a pressure drop produced by sucking out the air from the space lying between the moulding face and that face of the glass sheet on the opposite side from the glass sheet, in which the pressure drop is a maximum at the edge of the glass sheet and decreases towards the center of the glass sheet, because of fact that air is introduced via air-inlet apertures opening into the moulding face, the air is again extracted by subjecting suction apertures made in the moulding face inside the region covered by the respective glass sheet to a vacuum. Furthermore, pressure between the glass sheet and the moulding face also in the region where the air is introduced is set to a value at most equal to the pressure beyond the glass sheet, in order to avoid any formation of bulging. A shaping mould suitable in particular for implementing this process is also described.

  • Patent number: 5974836
    Abstract: A device used for the bending of plate glass sections (3) includes an oven (1), a bending chamber (6), an upper bending mold installed in the bending chamber (6) in such a manner as to be able to be raised and lowered, a duct producing a flow of hot gas in order to raise the plate glass sections (3) against the upper bending mold, a lower bending mold in the form of a frame that works together with the upper bending mold to ensure bending by compression of the plate glass that is held by the flow of hot gas against the upper bending mold, as well as a movable transport frame (20) which is used to pick up the bent plate glass from the upper bending mold and to transport it to a cooling station located downstream.
