摘要:
This invention relates to a device for machining the corner area (1) of frames welded together out of profiled pieces (2, 3) such as, for instance, window or door frames, comprising at least one machining tool (4, 5, 6) that can be moved by means of a tool carrier (7) into the appropriate machining position at the corner area (1) of the frame along an axis (y) extending diagonally to the frame corner (3) and along an axis (z) perpendicular thereto. In order to allow machining of the corner area of a window or door frame as well as machining of the profile section itself, it is proposed according to the invention that the tool carrier (7) can move another tool carrier (8) arranged laterally thereto for at least one machining tool (9) configured for machining the profile section (2, 3), whereby the second tool carrier can be moved at least along an axis (x) extending at an angle α relative to the axis (y) in the diagonal direction of the frame corner (1).

The invention relates to a method for producing window or door elements that have a profile frame made up of profile pieces, and that have at least one glass pane attached thereto. The profile pieces are pre-affixed to each other in order to form corner joints, and subsequently, the at least one glass pane is glued to the pre-affixed profile frame, so that the corner joints attain their stability from the glued-in glass pane.

摘要:
A bearing assembly for a cylindrical device, which is capable of assuring rapid exchange of the cylindrical device, comprising a bearing housing surrounding an antifriction bearing cage provided with roll bodies, wherein a circular opening remains open, through which the roll bodies protrude in order to be supported at the cylindrical device to be borne. The bearing housing is subdivided into two parts or housing members in a plane passing through the axis, so that one of the parts or housing members can be swiveled against the other. Also, the antifriction bearing cage is subdivided, namely into individual cages loosely joined together.

A nozzle of a dyestuff applicator has a cylindrical valve housing formed with an orifice obstructable by the tip of an electromagnetically displaceable needle which controls the outflow of dyestuff from a chamber in that housing. The chamber is sealed by a rubber diaphragm which is penetrated by the needle whose shaft is engaged by a pair of parallel membranes of spring steel peripherally clamped in an extension of the housing. Each membrane comprises a narrow outer ring with an inwardly projecting tongue split into two diverging branches which are interconnected at their free ends, near the diametrically opposite side of the outer ring, by a re-entrant web extending radially between these branches and terminating in an inner, needle-supporting ring concentric with the outer ring.

The invention relates to the printing of sheet-heavy-pile textile materials, especially carpets, characterized in that powdered dyestuff preparations are applied to the sheet of textile material in consistency with the pattern, preferably by the screen- printing or film-printing techniques, the dye is subsequently fixed by the action of heat and any constituents of the dye preparations which are not fixed are removed by suction or by washing. The new method is economical and causes no or little pollution.

Methods and apparatus for a structure function monitor provide for generation of parameters characterizing a refractive medium. In an embodiment, a structure function monitor acquires images of a pupil plane and an image plane and, from these images, retrieves the phase over an aperture, unwraps the retrieved phase, and analyzes the unwrapped retrieved phase. In an embodiment, analysis yields atmospheric parameters measured at spatial scales from zero to the diameter of a telescope used to collect light from a source.
摘要:
A group of cylindrical printing screens, rotatable about parallel axes, are journaled on a machine frame and carry coaxial gears in mesh with driving pinions on the frame. A bed, designed to support a substrate to be imprinted, is supported underneath each screen on the frame through the intermediary of elevation-adjusting wedges interlinked by a control rod. The sceens can be axially tensioned by mounting units, slidable on axially extending guide rods, which carry spring-loaded thrust bearings acting in an axially outward direction upon their coaxial gears.
