Abstract: The invention relates to a method for calendering paper, especially with so-called glassine calendering. The calender comprises press rolls arranged successively in the paper advancing direction whereby, at least between some of rolls, there are formed press nips for passing paper therethrough. Each press nip is preferably formed by a pair of rolls, one of which is hard and the other elastic. Paper is advanced into the calender at an initial moisture X within the range of 12 % </= X </= 25 %, at least one of the press nips having a calculable line pressure arranged higher than 250 kN/m. In operating conditions, the ratio X/LP between paper moisture X and calculable line pressure LP is maintained in the press nips within certain limits in a manner that the maximum value of ratio X/LP divided by the minimum value of ratio X/LP gives a reading Y, which is Y </= 2.15, whereby X refers to the moisture percentage of paper and LP is a line pressure at a particular press nip expressed as a quantity kN/m (kilonewton/meter). The invention relates also to a paper manufactured according to the method.

Abstract: The invention has as its object the provision of a method and an apparatus for the generation of smoothness and gloss on paper which essentially precludes a re-erection of the surface fibers after the smoothing process. This is achieved in that the surface of a paper web (1) to be smoothed is heated to a temperature above the glass transition temperature of the fibers at the surface of the web without subjecting the web to a press nip, and then these fibers are deformed and fixed in the deformed state in a subsequent process step under the simultaneous action of pressure with shock cooling. Accordingly, there is associated with each surface of the paper web (1) to be smoothed a heating device (2) and also a subsequent cooled body (5, 9, 10) which presses against the surface.

Abstract: The invention provides a process for the preparation of formic acid by hydrolyzing methyl formate with water at high temperature and pressure in the presence of a formic acid catalyst. Methanol is also formed. The reesterification of the reaction products to methyl formate (a reaction favored by high temperatures) is minimized by flashing the reaction product at relatively low pressure and temperature and thereafter distilling the residual liquid. Thus procedure separates the methyl alcohol from the formic acid with a minimum contact time and at a low temperature which does not favor the reesterification reaction. High purity formic acid may be obtained by subjecting the bottom from the vacuum distillation of further distillation. 
<??>In a preferred embodiment of the invention, prior to the main hydrolysis, the methyl formate is partially hydrolyzed to form the small amount of formic acid needed to accelerate the main hydrolysis step. Accordingly, the necessary formic acid catalyst is formed in situ, thus eliminating the need to add formic acid or to recycle product formic acid.

Abstract: This invention relates to a telecommunication system including a conference information system including a number of participants each equipped with a separate node (2, 4, 8), which conference nodes may be interconnected via a switching network (1) such as a public switched telephone network, and where each participant node (2, 4 , 8) is including means for receiving a sum conference information signal from the other participating nodes, means for adding the signal generated in each conference node to the sum signal, and means for controlling the conferencing functions. According to this invention all of the nodes (2, 4, 8) in the conference connection are interconnected in a complete conference ring (11) by means of one single connection (12) in which the information signals are transmitted from node to node in one single direction (arrow 12). Some of the advantages of this system are   a conference may be established even if the possibly centrally arranged exchange is not provided with a conference facility. The conference facility is introduced by equipment distributed in each node terminal. The line requirement is reduced to the half, but still the same traffic capacity may be handled by the system. all the nodes now get identical status in the ring, and therefore all of the nodes may be designed as quite identical circuits.   <IMAGE>

Abstract: Method and device for monitoring a downstream transmission medium which comprises a multiplicity of virtual, asynchronously time-shared transmission channels via which a data flow can be transmitted.  The data flow is composed of data cells comprising a control word group (header) and an information word group.  The header is read out in a monitoring device.  On the arrival of a data cell, a number of variables is incremented and processed to produce a corresponding number of assessment signals.          Each data cell header gives an indication of those variables which have to be incremented and processed, and of the mutation (incrementation) and assessment algorithms to be used in doing so.          Furthermore, one or more of the assessment signals are processed in accordance with a combination algorithm, deduced from the data cell header too, to form a control signal.

IPC: C07K19/00
Filed: 1990-06-14
Granted: 2000-08-29
Abstract: The invention includes novel fusion DNA sequences encoding fusion polypeptides which when expressed in a filamentous fungus result in the expression of fusion polypeptides which when secreted result in increased levels of secretion of the desired polypeptide as compared to the expression and secretion of such polypeptides from filamentous fungi transformed with previously used DNA sequences. The fusion DNA sequences comprise from the 5' terminus four DNA sequences which encode a fusion polypeptide comprising, from the amino to carbonyl-terminus, first, second, third and fourth amino acid sequences. The first DNA sequence encodes a signal peptide functional as a secretory sequence in a first filamentous fungus. The second DNA sequence encodes a secreted polypeptide or portion thereof which is normally secreted from the same filamentous fungus or a second filamentous fungus. The third DNA sequence encodes a cleavable linker polypeptide while the fourth DNA sequence encodes a desired polypeptide.      When the fusion DNA sequence is expressed either in the first or second filamentous fungus, increased secretion of the desired polypeptide is obtained as compared to that which is obtained when the desired polypeptide is expressed from DNA sequences encoding a fusion polypeptide which does not contain the second polypeptide normally secreted from either of the filamentous fungi.

Abstract: In a DC type C-shaped welding gun apparatus having a transformer mounted thereon, a center tap of the transformer is communicated to a movable gun arm via an ounce metal plate.  A rear end portion of a stationary gun arm is pressingly held between a pair of terminal plates via rectifiers.  Both terminal plates are disposed such that their center line is offset to one widthwise side of the transformer.  The stationary gun arm is thus disposed to one widthwise side of a projected area of the transformer.  The ounce metal plate for supplying electric power to the movable gun arm is disposed to the other side of the projected area.          In an X-shaped welding gun apparatus, a first gun arm is rotatably supported by a supporting shaft provided on a gun bracket.  A second gun arm is directly connected to one of feeder terminals of a transformer to constitute the second gun arm and the transformer into a unit.  This unit is rotatably supported by the supporting shaft via a supporting arm, and the other of the feeder terminals is connected to the first gun arm via the supporting arm.  The supporting arm is used as a feeder member.  The feeder member can thus be disposed within the width of the gun bracket.  A pressurizing cylinder is supported on the supporting arm along the transformer.  The vacant space around the transformer is utilized as a space for disposing the cylinder to thereby minimize the size of the welding gun.
