Abstract: A connector for securing the ends of a pair of optical waveguide fibers in optical alignment comprises a resilient base having a U-shaped groove adapted to receive the ends of the fibers and a clamp for deforming the base in a manner such that the sidewalls of the groove are brought into compressive engagement with the fibers. The compressive forces exerted by the walls of the groove bring the fibers into optical alignment and also secure the fibers against axial and lateral displacement.

Abstract: An attachment tool for a vacuum cleaner hose is disclosed comprising an elongate tubular housing having one end (12) adapted for connection to such hose and the opposite or working end flattened and providing an air intake opening insertable into crevices. Adjacent the flattened or working end, the housing is formed with single elongate opening (18) with means such as a sliding panel (19) being provided selectively to cover the elongate opening and control the admission of air therethrough. An elongate strip brush (22, 23) is mounted along each opposite elongate side of the elongated opening, the bristles of the brushes being preferably formed of short nylon and boar's hair bristles. By selectively opening or closing the cover for the elongated opening, the tool is readily converted from one which is suitable for cleaning crevices to one which is suitable for cleaning between relatively closely spaced surfaces such as, for example, venetian blinds, the strip brushes providing an improved and effective cleaning action in the latter mode.

Abstract: Die Schmelze wird unmittelbar im Anschluss an den Frischprozess im hierfür verwendeten metallurgischen Gefäss weitgehend abgeschlackt und es werden ihr sodann ausschliesslich durch den Gefässboden Gase und in Gasen suspendierte Feststoffe mittels feuerfesten Gefässbodensteinen zugeführt. Diese sind mit orientierten Durchgängen solcher Art versehen, dass sie gleichzeitig gasdurchlässig sind, ohne den Durchtritt flüssigen Metalls zu gestatten. Sowohl die Gaszufuhr als auch die Feststoffzufuhr wird je nach Bedarf eingeschaltet, mengenmässig gesteuert und unterbrochen. Zum Erzielen einer schützenden Deckschicht wird der Schmelze reiner Kalk zugeführt, wobei das Trägergas ein neutrales Gas ist. Anschliessend wird ein Deckel dicht auf das Gefäss aufgesetzt. Dann wird der Schmelze bis zum Erreichen einer Sauerstoffkonzentration von höchstens 35 ppm ein Gemisch aus metallischem Aluminium und aus Kalk im Mengenverhältnis von 1:1 bis 1:5 zugeführt. Nach dem Desoxydieren führt man ein Gemisch, das einen Anteil von 0-30 Gew.-% an metallischem Aluminium, einem Anteil von 0-20 Gew.-% an Flusspat und einen Anteil von 5-100 Gew.-% an Kalk aufweist, in die Schmelze ein.

Abstract: Press for the manufacture of frames, such as for example window frames or the like, having a press frame possessing adjustable transverse and longitudinal members. The basic framework consists of fixed uprights (5, 6) and fixed transverse members (2, 3). The upper pressing devices are arranged on an auxiliary member (20) which is displaceable parallel to the transverse members (2, 3). The two ends of this auxiliary member (20) are each connected to a chain drive (9, 10), so that this auxiliary member (20) can be moved up and down uniformly and in parallel. As a result, the upper pressing devices for the longitudinal pressing and the transverse pressing, including a transverse supporting device (43), are then set quickly, reliably and accurately at the desired frame height. The frame width is set in a known manner by displacing the movable longitudinal member (4) in parallel. This movable longitudinal member (4), as well as additional longitudinal members (44, 45 and 46) along which the longitudinal pressing devices (24, 25 and 26) are displaceable and lockable, is indirectly displaced in parallel and in the transverse direction by means of corresponding bearings (41, 42, 47, 48). <IMAGE>
