Abstract: A method of detecting defects present at the surface and/or internally in transparent materials, particularly of detecting included foreign bodies or bubbles in glass, is disclosed. The test material is scanned with an electromagnetic radiation of a single wavelength which is set to the penetration depth in the test material. The intensity reflected by the defects is picked up and analyzed. By this method only defects located up to a specified depth in the material are detected. Visible light as well as UV- or IR radiation may be applied. The associated test rig comprises a tunable Laser (2), a conveyor belt (6) carrying the test material (5), a fast rotating mirror-wheel (3) which directs the light beam (4) at high speed over the test material (5), and an optical sensor (7) connected with an analyzer unit (8).

Abstract: In order to decrease the number of different structural elements required and to expedite the assembly of a rapid-construction framework as a support structure for ceilings and wall plates of a building, modular connections are used, each having four shaped guide bars, for connection of supports with tie bars of the rapid-construction framework, which are brought into force- and form-locking engagement with the hollow spaces of the supports or hollow main elements at the ends of the tie bars, for the assembly of the framework. Main elements, which are hollow on the tie bar side, are of the same dimensions and are welded in the same manner to the ends of the tie bars. A leveling member 40 is of diameter to that of the supports.

Abstract: A process for the preparation and immediate use in situ of ready to use blends of structural material, such as plaster, mortar, stucco, tile adhesive or similar blends, which, in contrast to the usual methods does not use as a raw material a dry mixture of the three main components binder, filler and additives. Instead a dry mix of binder and filler is prepared at the building site, and an aqueous solution of the additives is added in a separate mixing operation, immediately followed by the application in situ of the finished blend. This method avoids the difficulties associated with the use of dry mixtures containing all three components. The invention includes an apparatus for mixing and immediate application of the blends as defined by the process claims.

Abstract: The insect trap of the present invention comprises a conical shell having a downwardly and inwardly tapered sidewall and an upstanding annular rim provided at the top of the sidewall. Baffles are positioned within the conical shell and extend upwardly therefrom. An insect receptacle is provided into which the bottom of the conical shell opens. The baffles of the insect trap preferably comprises four fins, each fin having a slot and an aperture formed therein. Flat insect lures which extend through the slots in the fins are provided in the baffles and a plug-like insect lure is positioned in the aperture in one of the fins of the baffles. The two types of insect lures effectively attract insects into the insect trap such that insects like the baffles, fall downwardly through the conical shell and are captured in the insect receptacle.

Abstract: With a lifting and depositing device for portable box-like articles, in order to be able to operate their rack and pinion jacks manually and with ease by crank assemblies, each crank assembly has a haft-like crankcase, which has at one end a rotatable crankshaft and at the other end a rotatable drive shaft, which can be connected with an adjacent rack and pinion jack having a winch housing. The crankshaft and drive shaft are operatively connected with each other so that the latter is driven by the former. The crankcase can be connected with an adjacent winch housing and be pivoted into different work positions as well as fixed in such positions on the winch housing. Thus, the operation of the rack and pinion jacks is especially simplified in their top and bottom end positions on the uprights of the lifting and depositing device.
