Patent number: 4236566Abstract: An external venetian blind is disclosed having a plurality of slats (10) which in the closed position overlap each other and at least two flexible lifting elements (14) extend through openings (20) in the slats (10). One edge (12) of each slat is offset along a bend line (15) to help in guiding the slats during opening and closing of the blind. In one embodiment shown in FIG. 1 the offset edge portion (12) lies substantially parallel to the lifting elements (14) while in the preferred embodiment of FIG. 3 the offset edge (12) lies at an angle of up to 10.degree. with respect to the lifting elements (14). This angle is preferably 3.degree. to 6.degree. with 5.degree. being the most preferred. The lower edge (17) of the slats (10) is rolled inwardly and has secured thereto a resilient sealing strip (18) to bear against the next lower slat in the closed position to insure quietness of operation and the secure elimination of light penetration through the blind.Type: GrantFiled: November 22, 1978Date of Patent: December 2, 1980Assignee: Hunter Douglas International N.V.Inventor: Erich E.

Patent number: 4237370Abstract: A pulse generator for metal machining by electric discharges, comprising a primary current circuit for producing and transmitting pulse forms to a pair of electrodes. A voltage and/or current source is arranged in the low-ohm and low-loss primary current circuit, the voltage of which has a value which is only that much greater than the operating voltage of the pulses flowing through the spark gap as is needed to positively overcome the voltage losses occurring in the primary current circuit. A signal generator produces a signal corresponding to the desired current pulse shape or form. A comparator, which has a switch arranged in the primary current circuit for regulating the current flow in such primary current circuit, controls the current flowing through the primary current circuit, as a function of the desired pulse form produced by the signal generator and a magnitude of the current flowing in the primary current circuit which is tapped-off by a measuring feeler.Type: GrantFiled: June 2, 1978Date of Patent: December 2, 1980Assignee: Elmapa N.V.Inventor: Werner Ullmann

Patent number: 4236567Abstract: This invention relates to a fastening member for securing the slats of a venetian blind onto a flexible support element and to the method of assembling such slats to the support elements. The fastening member comprises a generally "U" shaped member in which the legs of the "U" have at their outer ends laterally outwardly extending abutments for engagement on one side of the slat while the remainder of the fastening member extends through an opening through the slat. A loop on the flexible support element passes between the legs of the "U" thus tending to hold the abutments in engagement with the surface of the slat. On the opposite side of the slat cam locks are provided such that upon flexure of the legs toward each other the cams will pass through the opening in the slat and then upon release when the legs resume their normal position the cams will engage and lock the slat in position between the cam locks and the aforesaid abutments.Type: GrantFiled: June 2, 1978Date of Patent: December 2, 1980Assignee: Hunter Douglas International N.V.Inventor: Kurt H.
