Abstract: The working cylinder without piston rod is designed as a band cylinder, the band (3) in the cylinder covers (8) passing through a location chamber (10) for a sealing member and a guide member. The sealing member consists of a strip-like sealing element of elastic material on either side of the band, which sealing element can be designed as a lip seal on the piston side. The sealing elements (12, 13) are inserted into the location chamber (10) with elastic tensioning towards the band (3). The guide member arranged remote from the piston relative to the sealing member has a web-like guide element (23, 24) on either side of the band (3), which guide element (23, 24) is likewise pressed elastically against the band (3) by the tensioning of the sealing elements (12, 13). By means of stop surfaces (28), the guide elements (23, 24) end with a clearance gap (29) in front of the wall (15) of the location chamber (10). The result of this is that the band (3) can be elastically deflected from its desired position only by the clearance gap (29), positive-locking support of the guide elements (23, 24) on the cylinder cover (8) is then effected, and thus no further band deflection is possible.

Abstract: Use of a lithium salt, particularly lithium thiocyanate, as an agent for lysing red blood cells and denaturing hemoglobin in the performance of an immunoassay to detect the relative amount of a hemoglobin derivative in a blood sample. The method is particularly useful in the determination of hemoglobin A1c. The method provides a rapid means for releasing hemoglobin from red blood cells by lysis and for exposing the epitope that is characteristic of the A1c form. Low concentrations of the lithium salt provide rapid release and denaturation of hemoglobin without the need for dilution prior to the performance of the immunoassay.

Granted: 1992-12-23
Abstract: An actuating device preferably consisting of only two parts, namely a rotary member (1) and a device housing (2), can, because of the cross-sectional shape of its device housing (2), be installed in a lock, door, window or the like instead of a conventional lock cylinder of the same housing cross-section, so that the bolt of this lock can be transferred from the release position into the effective locking position, and vice versa, by means of the locking bit (13) of the actuating device. A 90 DEG -rotation of the rotary member (1) in the device housing (2) is sufficient for a complete stroke of the lock bolt. During assembly, the rotary member (1) assumes a rotary position in which, in the same way as with a lock cylinder, the locking bit (13) does not project laterally beyond the contour of the device housing (2). In a rotary position different from this, namely the working rotary position of the rotary member (1), and of course also on the way to this, the locking bit projects beyond the contour of the device housing (2). <IMAGE>

Abstract: Edible spreads are prone to microbiological spoilage by a number of organisms, including molds and bacteria as well as by physical changes occurring on storage. While the growth of these organisms and consequently the onset of spoilage can be inhibited by the use of preservatives, some consumers find preservatives unacceptable. We have determined that in edible fat products wherein the fat phase comprise a homogeneous dispersion of fine crystals and in which the fat phase is essentially free of crystalline aggregates spoilage is greatly reduced. Anhydrous products can be produced by melting the fat, substantially in the absence of an aqueous medium, cooling the melted fat to a temperature at which partial crystallization occurs, homogenising the partially crystallised fat, and, cooling the homogenised fat to further crystallise the fat. By means of a modified process it is possible to produce comprising 50-60% fat phase, 40-50% water phase, 0.1-1% lecithin, 0.01-1% salt, being essentially free of monoglycerides, proteins and sorbate salts, which are stable on storage.

Abstract: R- and S-1-Phenyl-1,3-propanediol, each of high optical purity, were prepared by a chemoenzymatic sequence starting with ethyl benzoylacetate. The first step was a catalytic hydrogenation of the β-ketoester conducted at room temperature. The enzymatic hydrolysis of the resulting hydroxyester proceeded in a facile manner using a commercial preparation of the lipase from Pseudomonas fluorescens. The enzymatic hydrolysis proceeded at a moderate rate (350 mg lipase/0.10 mol of racemic ester required a 20-hour reaction time with an enantiomeric rate ratio (E value) of 36). The hydrolysis was run to 45-50 % conversion to afford isolated S-3-phenyl-3-hydroxypropionic acid of 85-90 % ee after separation from the residual ester (aqueous base extraction). The optical purity of the hydroxy acid was determined by conversion to the methyl ester (CH3I, KHCO3, acetone), and derivatization with S-MTPA-Cl, and 1H NMR analysis. A single recrystallization of the isolated acid afforded optically pure (>98 % ee) S-3-phenyl-3-hydroxypropionic acid in an overall 36 % yield from the racemic ester. The acid was reduced with borane in THF to afford optically pure S-diol in 97 % yield after crystallization. The overall sequence proceeded in 34 % total yield from racemic ester with an additional 45-55 % recovered as the antipodal ester. This antipodal ester is obtained in 85-95 % ee, and the corresponding hydroxy-acid was readily obtained (NaOH, CH¿3?OH/H2O) and recrystallized to optical purity. Reduction then afforded R-1-phenyl-1,3-propanediol in 30 % to overall yield from racemic ester.

Abstract: A process for making foamed metal bodies is described, in which a mixture (17) of a metal powder (15) and a gas-evolving blowing agent powder (16) is thermocompacted to form a semi-finished product (19), at a temperature at which the bond of the metal powder particles predominantly takes place by diffusion and at a pressure which is high enough to prevent the decomposition of the blowing agent, in such a way that the metal particles are in a solid bond with one another and represent a gas-tight seal for the gas particles of the blowing agent. The foamable metal body may also be produced by rolling. Furthermore, use of the foamable metal body (19) thus produced for making a porous metal body (21) is proposed.

Abstract: The invention relates to a method and an apparatus for nondestructive testing of superficial layers, in particular of large construction pieces having complicated shape. Objects to which the invention relates are mechanical engineering, and plant and equipment construction pieces. In the method, the laser pulse is split, according to the invention, into two spatially separated subpulses of approximately equal intensity and the focal lines of both subpulses are located on the surface of the construction piece. The spacing between the two focal lines is adjusted by moving the beam splitter or individual components of the beam splitter or the like along the optical axis to an extent which depends on the geometry of the construction piece, the frequency of the ultrasonic waves and the attenuation and is kept constant for subsequent measurements. The method is carried out in an apparatus in which, according to the invention, a beam splitter is situated between the cylindrical lens and the surface of the test piece, an adjustable spacer is situated at the position of the two focal lines to fix the spacings between the beam splitter and the surface of the test piece and the ultrasonic test head is arranged on the continuation of the connecting line between the centres of the two focal lines.
