Abstract: The machine has a horizontal opening roller which possesses a roller body (1) and beating pins (3) projecting from the circumferential surface (4) of the roller body (1). Bar grids are arranged below the underside of the opening roller (13). Textile fibres in flock form are fed in a stream of conveying air through an inlet (7) which is arranged at a first end of the opening roller (13). At the other end of the opening roller (13) is arranged an outlet for the stream of conveying air. The radial length of the beating pins (3) decreases from the inlet (7) to the outlet, whilst the diameter of the roller body (1) increases from the inlet (7) to the outlet. This results in an improved opening of the fibre flocks and a more complete separation of impurities through the bar grids. …<IMAGE>…

Abstract: A gear defect analyzing system records the interaction of each tooth of a gear system until the interaction begins to repeat and then processes the information in such a way as to identify defective gear teeth. Signals from a gear box are detected by an accelerometer and a shaft encoder and fed to an interface circuit and then to an analog signal preprocessing circuit. The preprocessing circuit conditions the signal so that it can be analyzed by a microcomputer. The system has the capability of identifying the class of incoming signals, determining the optimal time domain average, eliminating unwanted spectral components and interference, computing specific measurements relating to gear wear and then performing analysis of time history within a given system operating state to determine which gears and gear teeth are defective. By recording each tooth-to-tooth interaction over a period of time, and then processing the recorded matrix of data, it is possible to locate individual tooth defects. The system is also capable of detecting, classifying, and analyzing other types of hard- to-find defects.

Abstract: The oil-collecting funnel (1) is fastened to the bottom end of the rail (3) by means of a clamp (2) and serves to collect the lubricating oil running down the rail (3). It is provided with a cover hood (5) which corresponds to the cross-section of the rail (3) and in the top area is at a small distance from the rail (3) all round the same and thus forms a gap which serves as "oil inlet" for the oil running down the rail (3). The oil-collecting funnel (1) has a base sloping away from the rail (3). Provided at the deepest point of the base is an opening (6) to which a tube (7) can be connected which leads into a container for collecting the oil flowing off. It is essential here that the oil-resistant seal (4) in the sloping base of the oil-collecting funnel (1) fills the entire intermediate space between the base recess of the oil-collecting funnel and the surface of the rail (3). The oil-collecting funnel is made of oil-resistant and impact-proof plastic. <IMAGE>
