Abstract: The invention relates to a process for deactivating the inner surfaces of capillaries for capillary zone electrophoresis and capillary gel electrophoresis.      The deactivation is effected by coating said inner surface with polar polymers which initially are water-soluble, whereupon the polymers are subsequently thermally fixed by a formation of water-insoluble polymers.      The invention further relates to the capillaries thus produced and to the use thereof for the separation of oligonucleotides, peptides and proteins.

Title: Device for separating perforated sections of a tubular web
Inventor: ACHELPOHL FRITZ
IPC: B31B50/02
Filed: 1993-12-17
Granted: 2004-03-23
Abstract: A device for separating sections of a perforated tubular web includes a pulling mechanism and a tearing mechanism. Each of these mechanisms has opposing rollers positioned facing each other on either side of the tubular section being separated. Continuous conveyor belts run over these rollers. The rollers of the tearing mechanism can be moved by a control element toward the tubular web. To prevent slippage of the web within the pulling mechanism when the tubular sections are being torn, the pulling mechanism is also provided with a control element which moves the rollers or cylinders of the pulling mechanism in a direction perpendicular to the tubular web in order to increase the pressure on the tubular web. The control element of the pulling mechanism is synchronized with a control element of the tearing mechanism.

Abstract: A batting practice apparatus is made up of a vertical supporting structure, that has a horizontal arm at its top end, from which is suspended a slideable tether.  The slideable tether rests between two protrusions on the horizontal arm.  A first of the protrusions is located near the free end of the horizontal arm, a second of the protrusions is located intermediately on the horizontal arm.  A resiliently compressible element (the 'element') is located between the second protrusion and the slideable tether.  The element is attached to the arm in such a way that it can be compressed by the slideable portion of the tether when the slideable portion slides against it.  Attached with the free end of the tether is a second tether which has a ball suspended from its free end.    Attached with the attached ends of the first two tethers is a third tether, which at its free end is attached to an intermediate point on the vertical supporting structure.

Abstract: A process for applying a metal coating to a nonconductive substrate without an electroless coating is disclosed. The process includes the step of: a. contacting said substrate with an activator comprising a noble metal/Group IVA metal sol to obtain a treated substrate; b. contacting said treated substrate with a self accelerating and replenishing immersion metal composition comprising a solution of: (i) a soluble metal salt whose metal is more noble than said Group IVA metal; (ii) a Group I A metal hydroxide; (iii) a complexing agent comprising an organic material having a cumulative formation constant log K of from about 0.73 to about 21.95 for an ion of the metal of said metal salt. The Group IVA metal is employed in a stoichiometric excess compared to the noble metal, the excess Group IVA metal being in its lowest oxidation state.  Selfaccelerating and replenishing non-formaldehyde immersion metal compositions are also disclosed.  The composition is used in a two step process to electrolytically coat a nonconductive substrate. In the first step the conductivity of the substrate is increased by applying the composition to it. In the second step, the substrate treated with the composition is electrolytically coated with a metal.

Abstract: A furnace for melting and refining E glass comprises a melting and refining tank for melting and refining the glass batch materials into glass and a forhearth, downstream of the tank, for further refining the glass and delivering the glass to fiberizing means. The melting and refining tank is heated with oxygen fired burners. The oxygen fired burners in the melting and refining tank are located in the sidewalk at the upstream end of the tank and extend for about one-third the length of the tank. In one embodiment, burners are also located in the upstream end wall. This arrangement of the oxygen fired burners at the upstream end of the melting and refining tank moves the melter hot spot upstream for better refining of the glass and enables the furnace to produce a higher output of glass than can be obtained in a conventional E glass furnace of the same size.

Abstract: The usable range of incidence angles for electromagnetic wave polarizers using arrays of polarizer elements (10) is increased by introduction of a dielectric medium (18) having a dielectric constant large enough to reduce the angle of wave incidence upon the polarizer elements. For example, arrays (10, 11, 12) of 45 degree inclined meander-line polarizer elements (14) are encased in a dielectric medium (18) having a dielectric constant of about 3. The polarizer (16) includes impedance matching layers (24, 26) at the surfaces of the dielectric medium (18) to reduce reflections at those surfaces. The resulting polarizer is indicated to be usable to reciprocally convert an incident polarization to a desired polarization (e.g., from linear to circular polarization) for waves with incidence angles from 0 to 70 degrees in any play. Polarizers, antennas and methods for changing polarization are described.

Abstract: A feed conveying apparatus is disclosed for use in a poultry or livestock feeding system (10). The feed conveying apparatus has a housing (14, 203) having a feed inlet (I) which receives feed from a feed supply (12, BFT) and a feed outlet (O). The housing has a body (24) which generally converges downwardly and inwardly from the feed inlet toward the feed outlet. A feed conveyor (16, 207) extends through the housing. The conveyor has a conveyor tube (17, 209) with a feed auger (18, 211) therein. The feed auger has a multiplicity of substantially equally spaced flights (62) and is driven within the conveyor tube for picking up feed from the housing and for conveying it through the conveyor tube. A regulator (58, 300) is provided for regulating the amount of feed within the conveyor tube downstream from the housing to an amount less than will totally fill the conveyor tube so as to form a partial void (V) within the conveyor tube and to prevent overcompaction of the feed within the conveyor tube. An agitator weight (144a, 219) is positioned within the housing which is movable by the auger as the latter moves within the housing. The agitator weight has a rod (164, 221) attached thereto for breaking up bridging feed within the housing above the level of the agitator weight.

Abstract: Volatile compounds, such as methanol, are separated from secondary condensates formed in multi-effect evaporation of waste liquor (e.g. black liquor) from cellulose pulp processes.  The condensable secondary vapor is condensed into first and second condensate flows, the first of which, smaller in volume, contains the majority of the volatile compounds condensed in the evaporating effect. The first condensate flows from one or more first evaporation effects, and/or condensers of the evaporation plant, are directed for cleaning into a first steam stripping column.  At least some of the second flows are directed to a second steam stripping column to be recovered as very clean condensate, cleaner than the condensate flow from the first stripping column and typically have a methanol concentration of less than 25 ppm, preferably about 10 ppm or less.

Abstract: An anode bar is disclosed particularly for utilization during the production of molten metal by the Hall-Héroult process in which an elongated copper rod is slit partially along its length and bent to define a generally inverted ? -shaped member defined by a base end portion, a bridging arm and a pair of generally parallel legs. Each leg is received in a sleeve and inserted into a ring with a polygonal opening in the ring matching a polygonal exterior surface of the associated leg. A weld intimately welds each metal ring to each leg end and covers the latter. By this construction there is an absence of current arcing, consumption of an associated carbon anode or anode block is reduced, as is the consumption of the ring, sleeve and legs, but upon partial consumption of any of the latter restoration is achieved in an efficient and low cost manner.
