Abstract: The invention relates to a calibration and cooling apparatus for extruded plastic tubes. In a run-through cooling chamber 1 which is under negative pressure and has spray nozzles 3a, 3b, which are for a cooling fluid and are directed at the through-running tube 8, there extends from the inlet to the outlet of the tube 8 a guide element 2a, 2b, which is arranged slightly outside the operationally required position of the through-running tube 8. The guide element 2a, 2b is provided with a plurality of openings, through which spray nozzles 3a, 3b arranged behind them spray the cooling fluid onto the through-running tube 8. Provided at the inlet and at the outlet of the run-through cooling chamber 1 there are calibrating and sealing rings 7a and 7b, which comprise part-rings and can be opened out for the purpose of easier introduction of the beginning of the tube into the run-through cooling chamber 1. <IMAGE>

Abstract: The invention relates to a longitudinal laminate board (1) of binder fixed mineral wool, which is suitable as a core of a sandwich element having surface layers of e.g. thin sheet metal. The laminate board consists of adjacently disposed longitudinally oriented rods (2), whose fibre plane forms a right angle to the plane of the laminate board. The rods are shorter than the laminate board and jointed to each other. The joints are distributed over the laminate board so as to eliminate their weakening effect on the resistance of the board. The total joint surfaces of the laminates form, within an interval (a) of the board, in which (a) depends on the length of the board and the number of laminates in the width, maximally one third of the cross-section of the board. As to areas of the length (a) next to the end faces and next to the support lines of multi-field boards, higher requirements of absence of joints are then posed on interposed areas.

Abstract: Corruption of communication signals on a telephone line (32, 33) by the direct (low impedance) interfacing of test equipment (20) to the line is precluded by a protective interlock circuit, which prevents the test set from seizing the line if data traffic is present. The interlock circuit is coupled between the line circuit to be accessed and the test equipment, and includes a multiple band frequency detector (31), which monitors the line for signals lying within (in and out-of-audio) frequency bands. Should the detector identify any traffic within its sensitivity range (out of the audio band) during the interval of a timing pulse produced by the closure of a switch (51), the logic level applied to combinational logic will change state and prevent the generation of a test set enabling signal.

Title: A process for producing pentapeptides and intermediates for use in the synthesis
IPC: C07K16/06

Granted: 1993-06-09
Abstract: Pentapeptides having the formula H-Asp-Ser-C-Pro-Arg-OH, where Asp, Ser, Pro and Arg may have L- or D-configuration, and C denotes Asp or Asn in L or D configuration, are synthesized by reacting in an aqueous medium Y2-Pro-OH, wherein Y2 is a protective group, with Arg-Ro, wherein Ro is OH or is as defined below for R1 below, to form Y2-Pro-Arg-Ro, which is deprotected, if necessary under conversion to Pro-Arg-R1, wherein R1 is an enzymatically cleavable  alpha -carboxy substituting group selected from esters, amides, anilides, hydrazides or L-amino acid esters, and thereafter reacting Y3-C(Z3)-OH with Pro-Arg-R1 to form Y3-C(Z3)-Pro-Arg-R1, which is deprotected to C-Pro-Arg-R1, and then reacting Y4-Ser-OH with C-Pro-Arg-R1 to form Y4-Ser-C-Pro-Arg-R1, which is deprotected to Ser-C-Pro-Arg-R1, and reacting Y5-Asp(Z5)-OH with Ser-C-Pro-Arg-R1 to form Y5-Asp(Z5)-Ser-C-Pro-Arg-R1, which is deprotected to the intermediate Asp-Ser-C-Pro-Arg-R1, and finally removing the group R1 with an enzyme, preferably trypsin to form Asp-Ser-C-Pro-Arg, or removing R1 from Y5-Asp(Z5)-Ser-C-Pro-Arg-R1 before deprotection to Asp-Ser-C-Pro-Arg-OH. The groups Y2, Y3, Y4, Y5, Z3 and Z5 are protective groups which apart from Y2 are removable by catalytic hydrogenation. The employed synthesis strategy based on the combination hydrogenation/enzyme, both proceeding under mild conditions, leads to the peptides, in particular HEPP, in good yield without risk of formation of  beta -aspartyl peptides and cleavage of Asp-Pro bonds.

Abstract: A process for thermically recovering old sand obtained in casting plants and for treating dust containing combustible organic components and incombustible inorganic components is disclosed. Dust obtained by mechanical preparation of the old sand is separated from the sand. The sand is used to form a fluid bed in a fluid-bed kiln having a post-combustion space and an outlet for releasing combustion gases. Dust containing combustible organic components and incombustible inorganic components is introduced into the fluid bed, the combustion of the organic components being used to maintain reaction temperature in the fluid bed. The heat of the fluid bed and the post-combustion space deactivates inorganic components of the dust, which are transported by released combustion gases to effectively separate the inorganic components of the dust from the thermically recovered old sand. These deactivated inorganic components of the dust can be separated from the released combustion gases for easy disposal.

Abstract: A composition for removing organic contaminants, such as flux residues, from a solid substrate comprises: (a) hydrogen peroxide in the amount of about 3 to 5 percent by weight of the composition; (b) an alkaline compound in sufficient amount to provide a pH of at least 10,5 in the composition; (c) about 0,1 to 0,3 percent by weight of a chosen wetting agent which is unreactive with the hydrogen peroxide and the alkaline compound; and (d) purified water as the balance of the composition. Optionally, the composition may further comprise about 0.5 to 2.0 percent by weight of a chosen metal protective agent. The solid substrate having organic contaminants thereon is exposed to the above-noted composition whereby the organic contaminants are removed from the substrate and are converted into non-toxic and non-hazardous products. Thus, negative environmental impact is avoided by the present process. In an alternative embodiment, the organic contaminant removal is further enhanced by exposing the composition and the organic contaminants on the substrate to ultraviolet radiation.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by casting a photosensitive resinous material over and through the reinforcing structure while the reinforcing structure travels over a textured surface, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
