Abstract: ABSTRACT         Chromatographic  procedures  are  individually and jointly applied to the rapid and efficient isolation of biologically active proteins and especially glycoproteins such as recombinant erythropoietin present in the medium growth of  genetically transformed mammalian host cells. Illustratively,  recombinant EPO is isolated from culture fluids by reverse phase chromatography employing a C4 or C6 column and elution with ethanol.   Practiced serially with purification  by  anion  exchange  chromatography,  the  two chromatographic  procedures  allow  for  high  yields  of biologically active recombinant erythropoietin from mammalian cell culture media.

Abstract: A method and apparatus for minimizing the visual degradation of a typeface wherein the need for the manual input of skilled technicians is eliminated and the important visual components of each character and the relationship of the visual components of each character with the other characters of the typeface are preserved. The characters are analyzed to determine the visual components in the horizontal and vertical direction which comprise each character and the priority of adjustment. Using the visual components determined, starting with the highest priority component, the coordinates describing each character are adjusted according to rules which are dependent upon whether the strokes formed are oriented in the horizontal or vertical direction. The adjustment of the lower priority visual components isdependent on the previously aligned components. The important visual components in the diagonal direction are subsequently adjusted in accordance with similar sized visual components in the horizontal and vertical direction wherein the dimensions of the adjusted horizontal and vertical components are maintained.

Abstract: The invention relates to a mower comprising a chassis which is provided with an engine. The chassis consists of a front and a rear section each section being provided with a pair of wheels and the front section supports a cutting attachment. The front and at least a part of the rear section are pivotally connected to each other so that they can be turned mainly about a vertical steering axis and about a mainly horizontal swinging axis. The steering axis (29) and the swinging axis (42) is placed considerably closer to the wheel axis of the rear section (13) than the wheel axis of the front section (12) preferably so that the distance (a) between the steering axis (29) and the wheel axis of the rear section (13) is less than ⅓ of the distance (b) between the two wheel axis.

Abstract: An arrangement for sealing the gap between two mutually concentric machine parts (52, 56), which move with respect to one another, comprises a sealing ring (53) which is inserted in the slot (51) of a first machine part (52) and consists of tough elastic plastic, and which rests with sealing edges (57, 58) arranged close to its ends on a second machine part (56), and a clamping ring (54) which is arranged between the sealing ring and the base of the slot, stresses the sealing ring radially and consists of an elastomer material whose axial expansion is less than that of the sealing ring. In this case, fixing the clamping ring (54) in the centre of the sealing ring (53) causes difficulties. 
<??>In the sealing arrangement according to the invention, the sealing ring (53) has an annular slot on its surface facing the slot base (63), which annular slot holds the clamping ring (54) and has an essentially trapezoidal cross-section, and the sealing ring (53) moreover has a least one radial hole (67) connecting the space (71) between the sealing edges (57, 58) and the base of the annular slot. In consequence, the clamping ring (54) is not only fixed correctly with respect to the sealing ring (53) but also ensures good stress relief of the sealing ring (53) while at the same time avoiding the sealing ring lifting as a result of excess pressure building up between its sealing edges (57, 58).

Abstract: Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.

Abstract: A polyfunctional reaction product having functional phenolic OH groups is made available by reacting a phenol and an alkoxylated amine-aldehyde condensation product in the presence of a solvent and of an acid catalyst. This method makes it possible to prepare a polyfunctional phenolic reaction product which is soluble in organic solvents at a low ratio of phenolic OH groups to alkoxy groups without gelling. The reaction product is particularly useful as a curing agent for epoxy resins.

Abstract: Pivotable adjustment mechanism is provided for the connection of two mutually moveable members. Such members can be a seat portion and a base support portion of a chair, two cooperating, shaft forming members of an apparatus, a machine, etc. The adjustment mechanism includes two concentric rings suspended according to the cardan principle. The two rings each have a torsion bar disposed along a diameter of and securely fastened to its ring for adjustment of the latter, the two torsion bars being arranged at right angles to each other. A first member is fastened to the outer ring which is suspended by rotatably mounting the ends of its torsion bar in brackets secured to the inner ring which is axially displaced of the outer ring. The inner ring is suspended by rotatably mounting the ends of its torsion bar in a bracket secured to a second member of the chair, apparatus, machine, etc. The torsion bars of the outer ring are secured at their centers against rotation relative to the inner ring and the bracket secured to said second member respectively. This provides a more robust construction with the use of torsion springs which provides a longer lifetime for the springs and less noise in the springs during use.

Abstract: A means for measuring milk drawn with a pipe milking machine, particularly in systems according to the Patent F1 65697, in which the milk is pumped from a centrepiece (2) by a vacuum pipe (4) with the aid of a pump (6) into a milk pipe (12) under normal pressure. The pump of said Patent operates under control by the pulsator of the milking machine. Hence follows that the piston strokes are different in length, and therefore their number does not give the exact milk quantity. As taught by the present invention, the operation of the pump takes place under control by vacuum so that the extreme positions of the pump's piston control a control valve (24, 24'). The control valve admits the vacuum alternatingly on either side (8, 10) of the upper part of the pump piston (7). The piston stroke length thus obtained is accurate enough, whereby the piston stroke with the aid of the readings of a counter (25) yields an accurate enough milk quantity measuring result. The means also enables a sample quantity of desired magnitude to be taken.

Granted: 2000-01-11
Abstract: A take-apart tire and wheel assembly including a mufti-piece wheel rim having axially spaced bead flanges, a rim base, and a pneumatic tubeless tire, preferably adapted to removably receive in its tire inflation chamber a safety runflat insert. The wheel assembly also includes a safety vent for preventing inflation of the tire cavity in the event of improper assembly or disassembly of the safety tire and wheel assembly, including an O-ring seal disposed between opposing portions of rim segments of the wheel assembly, and mounting studs and associated nuts that releasably clamp the rim segments together with the O-ring captured in compression therebetween. The outboard wheel rim segment includes a wheel mounting disc and also a safety inflation valve coupling fixed to the outboard rim segment. An interior air passage of the coupling communicates with the tire cavity and has a maximum cross sectional dimension less than the minimum exterior cross sectional dimension of an air inflation valve provided on an inner tube of sufficient size to fit within said tire cavity and capable when inflated of rendering said wheel and tire assembly normally operable for supporting its normal vehicle load in a run-mode of the vehicle.      The safety inflation valve coupling is thus operable to prevent insertion of such an inner tube valve through the interior air passage of the wheel safety inflation valve coupling.
