Abstract: A trench drain connection interface for connecting a first trench drain to a second trench drain. The trench drain connection interface comprises a male end, a female end, and at least one protrusion. The male end of the first trench drain has a flange. The female end of the second trench drain has a flange-receiving recess. The at least one protrusion is on at least one of the male end and the female end. The male end of the first trench drain is configured to engage the female end of the second trench drain and when the male end engages the female end, the at least one protrusion prevents at least a portion of the flange from contacting an inner surface of the flange-receiving recess, thereby providing clearance between the flange and the inner surface of the flange-receiving recess.

Abstract: A method and a device are provided for contamination-free and/or sterile sealing between two interconnectable connecting elements having opposing openings. Interconnection allows transfer of a fluid between the openings. Sealing elements are arranged on the connecting elements around the openings, and protective films are provided, covering the sealing elements and the openings and adapted to be removed in the final interconnection.

Abstract: An illumination system having spatially separate horizontal and vertical intermediate image planes. A beam expander is used to expand a laser beam and direct the light to a lens array. A condenser projects and concentrates the light from the lens array into a spatially separate vertical and horizontal intermediate image planes. A relay re-images the spatially separate vertical and horizontal intermediate image planes at a single plane at a reticle. The image of the reticle is thereby projected onto a wafer. Width adjusting means and height adjusting means are located at the respective horizontal and vertical intermediate image planes. The zoomable beam expander is used to change the partial coherence independently in both planes without loss of light. The changeable lens array is used to independently change the two-dimensions of the field of view of the illumination system without loss of light.

Abstract: A brake hose coupling for coupling to a glad hand body. The glad hand body has a primary port and a pair of primary flanges bordering and angularly spaced about the primary port. The brake hose coupling has a coupling body with a complementary port and a pair of complementary flanges adapted to rotate coaxially into engagement with the primary flanges of the glad hand body The complementary flanges border and are angularly spaced about the complementary port. The brake hose coupling also has a lock with a latching member mounted to reciprocate on the coupling body adjacent and transversely to one of the complementary flanges, between a release and an engage position. In the release position the latching member has clearance to allow passage of a corresponding one of the primary flanges. In the engage position the latching member blocks passage of the corresponding one of the primary flanges. Thus the latching member is operable to lock the coupling body on the glad hand body.
