Abstract: Large tanks are built by welding pre-formed plates in operations near the ground. An annular concrete base with extended lifter pads is poured. Floor plates are lifted using lifting nuts, are placed on compacted sand and river gravel and are welded laterally. Peripheral templates are welded to the floor. Nested pre-curved plates are transported vertically. Forklifts move the plates using cleats, yokes and turntables. Pre-curved plates are welded vertically, forming a first ring. A roof is built on and welded to the first ring. The first ring and roof are lifted with self-climbing hydraulic lifters on lifting pillars. Additional rings are assembled in sequences of plate positioning, vertical welding, lowering the above structure using guides and spacers, horizontal welding, lifting, repeating the steps, and finally welding the bottom ring to the floor.

Abstract: The present invention relates to a method and an apparatus for wrapping bundles of printed matter by placing a folded film sheet around such bundles when these are conveyed to and through a wrapping station. The apparatus includes a lower, through-going belt conveyor with mutually separated conveyor straps and a couple of overhead band conveyors in line with each other creating a transverse gap between them. Below the spaces between the lower conveyor straps and just below the gap a transverse row of compressed air nozzles directed upwards is arranged.

Abstract: A pipe fitting element comprises a tubular fit-in sleeve (1) which can be fitted into an end of a pipe (2) to be connected, and a clamping ring nut (10), coaxial to the sleeve (1). The pipe (2) is arranged to be clamped by tightening the ring nut (10) on the sleeve (1) and translating it towards the pipe (2) while drawing two clamping surfaces (5, 13) mutually closer. One of the surfaces is situated on the outer surface of the sleeve (1) and the other situated on the inner surface of the ring nut (10). These clamping surfaces (5, 13) consist of progressive widening (105, 113) of the outside diameter of the sleeve (1) and of the inside diameter of the end of the ring nut (10) turned towards the pipe (2). A pipe joint, which has at each end a pipe fitting element of the above described type is also provided.

Abstract: A device for rapidly collecting tissue samples from organisms serves as a reaction chamber. It includes a solvent used to extract the analyte, a filter, and optional bioconcentrators. The filtered suspension is irradiated with a predetermined wavelength and the emitted, scattered, or reflected photons transmitted to a detector that identifies and quantifies the analyte. The bioconcentrators may consist of antibodies and colloidal metal nanoparticles that enhance emission of Raman signal frequencies by analytes bound to the antibodies. Alternatively, the device may contain only the extraction solvent and a filter.

Abstract: The invention relates to a transport vehicle which serves to transport objects having large dimensions, especially glass stands. The transport vehicle is provided, as a low-platform railway car, with a traversal loading area. This loading area and the loading ramps assigned thereto form a travelling surface for so-called Osila glass transport vehicles, whereby the loading area is protected against soiling in an overall manner by a structure, and the load is secured on the loading area by stand fixing devices and load securing devices.

Abstract: A window operator, particularly, operators for venting casement windows is provided. The base housing of the operator is of a plastic polymer, which is a non-corrosive and non-thermal conducting material. The top and bottom base components are then sonic welded with a heat-treated steel worm gear welded inside of the plastic base of the window operator creating a one-piece assembly. The worm gear and pinion gear with attached operator arm are placed within the base body before fusion welding the top body. The use of the plastic polymer for the base housing eliminates the possibility of corrosion of the base material. Also, the polymer does not require finishing or painting to protect it from corrosion.

Abstract: Excitations from engines of the launch vehicles and the aerodynamics of flight produce large vibrations which are very detrimental to spacecraft during launch. Whole-spacecraft vibration isolation systems that greatly reduce the transmitted structure-borne vibrations to the spacecraft are disclosed. The disclosed devices, when combined together into an isolation system, provide vibration isolation for the complete spacecraft and are the only connection between the spacecraft and the launch vehicle. Devices that provide isolation in the axial (thrust) direction are disclosed. These devices consist of an arrangement of damped metallic flexures and machined springs, which provide relative flexibility in the desired direction. Passive damping is provided by compressing and shearing viscoelastic materials.

Abstract: A method for the face-to-face weaving of a pile fabric whereby on a weaving machine in successive insertion cycles in each case two weft threads (1), (2) are inserted almost simultaneously between binding warp threads and pile threads, so that two backing fabrics are woven, pile threads (3), (4), (5) have parts which form pile according to a two-shot weave and have other parts which are inwoven in a backing fabric, and two married pile threads (3), (4); (4), (5) perform a pile change. The successive positions (B=bottom; M=middle; T=top) of each pile thread (3), (4), (5) are predetermined in relation to the weft threads (1), (2) in a series of successive lift plans, of which every lift plan determines the positions in relation to the weft threads (1, 2) of two successive insertion cycles.
