Abstract: The electrical plug for flat cables has three rows (A, B, C) of terminal contact pieces (1), which are supported at a specific distance from one another in retaining holes (20) in a longitudinal dielectric material body (4). The said contact pieces (1) are in each case connected via a central connecting section (2) to cutting contact pieces (3), having a different spacing with respect to one another than the terminal contact pieces (1). A conductor (8) of the flat cable (9) can in each case be pressed into the cutting contact pieces (3), penetrating the insulation surrounding the conductor. A structurally and functionally particularly satisfying embodiment comprises cutting contact pieces (3) which are distributed on two parallel rows which are located essentially in planes between the three planes which govern the position of the three rows (A, B, C) of terminal contact pieces (1). A square dielectric material block (6), which is provided with holes (7) for the cutting contact pieces (3), can be inserted in a cut-out (5) formed on the top of the dielectric material body (4). Two channels (13, 14 or 34, 35), which are separated from one another, extend in the longitudinal direction, and are defined by the dielectric material block (6) or the dielectric material body (4), are provided for holding the central connecting sections (2). <IMAGE>

Abstract: What is illustrated and described is a method for automatically detecting faults in moving textile webs, especially fabrics, by the use of a light source and an optoelectronic sensor, by means of which the light flux transmitted or reflected by the textile web is picked up and the luminous intensity values determined are transferred for evaluation to evaluation electronics. The hitherto existing problem of sensing structured sheet-like formations for faults continuously and with a high degree of accuracy at high speeds of the textile web is solved, in principle, in that a textile-web strip oriented in a line along fault events to be expected and essentially transversely relative to the direction of run of the textile web is sensed by means a plurality of sensor elements, the associated surface elements of the textile web are detected essentially independently of one another and simultaneously and signals corresponding to the grey values of the surface elements are formed, in that the imaging scale of each sensor element is selected so that a plurality of identical structural elements of the textile web are detected at a time, and in that signals from the individual sensor elements are stored intermediately for column comparison with further detected strips, and in that the signals of longer-lasting deviations in the grey value are compared, if appropriate after amplification in a filter circuit, with reference values which were determined before the measurement by means of the values of a textile sample considered to be fault-free.

Abstract: In the method, the linseed is coarsely ground in order to break open at least the seed casing. Most of the linseed oil is pressed out of the coarse linseed meal. The linseed cake is finely ground. The linseed meal is treated, in order to extract the remaining oils and fats, with an extractant which is suitable for this, and which is subsequently removed again. In addition, either at the same time as the oil and fat extraction or separate therefrom, the water content of the linseed meal is also expediently reduced.

Abstract: A seal assembly for closing the end of a bearing includes a seal (40) and a shield (42) to which the seal is bonded. The shield has an axially directed mounting portion (50), an axially directed overhang (56) and a radial end wall (54) between the mounting portion and overhang. The seal has a pumping labyrinth (70) presented toward the mounting portion, yet spaced from it, a dirt lip (72) directed obliquely toward and contacting the mounting portion, and a secondary lip (74) directed obliquely toward but normally spaced from the overhang. The labyrinth is exposed toward the interior of the bearing and has pumping cavities (86) which impel lubricant back into the bearing. Between the dirt and secondary lip is an annular groove (78) containing a ring of lubricant grease which extends up to the radial wall and forming a barrier to the ingress of contaminants. If the ring of lubricant becomes temporarily pressurized, it deflects the secondary lip (74) against the overhang (56) to prevent excessive leakage, the pressure being relieved through vent notches (112) in the contacting edge of the lip.

Abstract: Slack waxes and synthetic wax (1) are isomerized and processed into high viscosity index (VI) and very low pour point lube base stock oils and blending stocks (11) by the process comprising the steps of optionally hydrotreating (3) the wax, if necessary, to remove heteroatom and polynuclear aromatic compounds and/or optionally deoiling the wax , if necessary, to an oil content between about 5-20% oil, isomerizing (5, 7) the wax over a catalyst of Group VI-Group VIII metal on a halogenated refractory metal oxide support, said isomeriza­tion being conducted to a level of conversion such that about 40% or less unconverted wax remains in the 330°C+ (preferably the 370°C+) fraction sent to the dewaxer. The total isomerate from the isomeriza­tion unit is fractionated (8) into a lube oil fraction (9) boiling at 330°C+, preferably 370°C+. This oil fraction is solvent dewaxed (10), preferably using MEK/MIBK at 20/80 ratio, and unconverted wax (12) is recycled (12A, 12B) to the isomerization unit. Operating in this manner permits one to obtain isomerate oil (11) of very high VI (in excess of 130) possessing a low pour point (-21°C, preferably -24°C, most preferably -27°C).

Abstract: A wafer clamping mechanism includes a clamp ring having a central opening corresponding to the geometry of a conventional semiconductor wafer. An overhang located about the opening engages the corresponding semiconductor wafer when in place on an electrode of a plasma reactor. The clamp ring is resiliently mounted on a housing which holds a second electrode. The clamp ring is automatically engaged against the wafer as the spacing between the two electrodes is adjusted to a desired gap width. A raised annular barrier on the lower electrode circumscribes the wafer and engages a mating surface on the clamp ring in order to enhance alignment of the clamp.

Abstract: An electrohydraulic proportional valve (10) in a two-stage type of construction is proposed in which control means engaging in the pilot circuit (42) influence the pressure build-up in a control space (27) at the main control spool (17) and thus its deflection in order to meet preset safety requirements. An auxiliary connection (C) provided on a standard valve is connected via a longitudinal groove (47) at the main control spool (17) to the control space (27), to which pressure can be admitted by the pilot valve (13), and can be relieved of load to the tank via an additional manipulating valve (14). Even when the pilot valve (13) is performing a regulating function, unintentional deflection of the main control spool (17) in certain directions can thus be prevented, so that only desired pressure-medium connections can be produced by the main control valve (12). <IMAGE>

Abstract: Synthesis gas is produced by the partial oxidation of a feedstock comprising a high silicon and sulfur-­containing heavy liquid hydrocarbonaceous fuel and/or petroleum coke or tar sands having nickel and vanadium-­containing ashes in admixture with a silicon and manganese-­containing ash fusion temperature modifying agent in a vertical free-flow unobstructed reaction zone lined with a refractory which comprises in wt. %: silicon-containing material about 95 to 99.8, iron oxide about 0.1 to 1.0, Al₂O₃ about 0.1 to 1.0, CaO about 0 to 0.4, and others about 0 to 1.2. In the reaction zone separate portions of said silicon and manganese-containing additive (i) combine with a portion of said Fe, Ni, and S to generate a first liquid phase washing agent which washes a portion of the high melting vanadium and oxide phases from the reaction zone, (ii) combine with a portion of said Ni, Ca, Si, Al, Mg and Na and/or K to generate a liquid oxide-silicate phase that fluxes and washes substantially all of the remaining vanadium and other ash components, and (iii) combine with a portion of the molten ash from the fuel and a minor portion of the refractory lining said reaction zone to increase the amount of said liquid oxide silicate phase and thereby enhance the removal of the vanadium from said reaction zone. By this method molten slag having a reduced viscosity and containing the nickel and vanadium-containing impurities from the feedstock and refractory components are readily removed from the gas generator.
