Abstract: Paper and paperboard of high dry strength are produced by adding a dry strength enhancer to the paper stock and dewatering the paper stock with sheet formation by using as the dry strength enhancer a mixture of a cationic polymer which contains as characteristic monomers copolymerized units of (a) diallyldimethylammonium chloride, (b) N-vinylamine or (c) a substituted or unsubstituted N-vinylimidazoline and has a K value of not less than 30, and natural potato starch which is converted into a water-soluble form by heating in an aqueous medium at above the gelatinization temperature of natural potato starch in the absence of any oxidizing agents or alkali.
Patent EP-0285838-B1 (EP)
IPC: G04C13/02
Filed: 1988-03-10
Granted: 1991-10-09
Abstract: In this clock (11) an energy storage device (25) charged with energy derived from ambient irradiation - preferably by solar cells (26) - is used as the operating power supply. The storage capacity can be made relatively small if all parts providing optional functions, such as additional functions not essential for the time-keeping function (especially those which are in any case hardly effective in the dark or could even be a nuisance) are temporarily disabled until, as the irradiation again increases, there is again an adequate reserve of energy for all functional parts. If, in fact, the drive for one of the time-indicating hands (17) is switched off when the energy reserve is low, it is advisable prior to this to move the hand concerned to an angular position which indicates that it is temporarily out of action. Switching off can be arranged by means of either radiation-controlled and/or voltage-controlled disconnecting switches (29); or, in addition to the main storage device (25) used for functions critical to the time-keeping function of the clock (11), a supplementary storage device (25) of very low capacity which does not place a load on the main storage device can be charged from the radiation generator (solar cell 26) to operate the optional additional functions. <IMAGE>

Abstract: Animal derived cells, especially erythrocytes, have been artificially modified (and referred to as engineered erythrocytes or RBCs) so as to incorporate in their plasma membranes an antigen, CD4 protein derived from lymphocytes, which will cause them to selectively seek out and fuse with other cells that are infected with a virus, especially the AIDS virus. These modified cells can be further altered so as to contain in their cytoplasm a cytotoxic agent which, after the cell has fused with a target cell, will result in the pooling of their respective cytoplasms and the death of both cells, with subsequent removal by the reticuloendothelial system. The invention also includes the production and use of similarly modified liposomes. The present invention can be used as a treatment of Acquired Immune Deficiency Syndrome (AIDS).

Title: Device with a cable drum for lifting or lowering a person under his own control
IPC: B66D1/04
Filed: 1988-12-16
Granted: 1992-05-20
Abstract: The carrying line (5) on which a person can be suspended by means of a safety harness is lowered or raised in a controlled manner via the cable drum (1). The endless drive cable (16) running over the drive wheel (15) serves to control the movement. The lifting is effected by the suspended person pulling on one side of the cable, by the control and drive mechanism (12) via the reduction gearing (14), whereas the friction coupling between the drive wheel (15), the notched wheel (21) with the friction linings (210, 211) and the flange sleeve (20) of the main shaft (2) is released by pulling on the other side of the drive cable (16), and the controlled and braked lowering is effected by the drive cable. When the person lets go of the drive cable (16), full braking is immediately effected. The catches (24) engaging in notches (22) provide a safeguard against return travel during lifting. The device can be used for any activity on perpendicular walls or masts where secured suspension from the topmost part is possible. The advantage consists in the fact that the person fastened to the device can move up or down without an additional aid and can be secured and can work with both hands when stopped. <IMAGE>

Abstract: Bei der diskreten Wafer-Scale-Integration, kurz WSI genannt, werden vorgetestete Chips (C1-C16) auf einem vorverdrahtetem Wafer (W) montiert und gebondet. Als Wafersubstrat dient meistens Silizium, weil die Waferverdrahtung kostengünstig mit einem Standard-Mehrlagenprozess erzeugt werden kann. Die Leitungseigenschaften einer solchen Wafermikroverdrahtung verbieten den Gebrauch langer Zuleitungen bei hohen Zeittakten, so dass Zwischentreiber (Tr1-Tr4) eingesetzt werden müssen. Bisherige Lösungen bedienen sich separater Treiberchips, die zusätzlich zu den eigentlichen Funktionschips plaziert, gebondet und getestet werden müssen. In einem nach der Erfindung vorgeschlagenen WSI-System werden die Zwischentreiber nicht als separate Chips realisiert, sondern auf dem Funktionschip selbst implementiert.

Abstract: A loudspeaker enclosure (1) operates in accordance with the acoustical band-pass principle and exhibits an external housing (2) in which an internal baffle board is provided with preferably two loudspeaker chassis attached thereto. The two loudspeakers (4, 4a) enclose a coupling volume between themselves and are located in chambers (5, 5a) which are sealed against one another. These chambers are connected to the external area via reflex openings (7, 7a). The loudspeaker chassis are acoustically connected in series and operate in phase acoustically. Having the same frequency response compared with a reference loudspeaker enclosure with one loudspeaker, this results in an approximate halving of the housing volume. In addition, distortions of the individual loudspeaker chassis are largely compensated for. The load-carrying capability of the loudspeaker enclosure is increased in accordance with the number of loudspeaker chassis, the use of two loudspeaker chassis resulting in approximately a doubling of the load-carrying capability. More than two loudspeaker chassis can also be arranged acoustically in series and operating in phase. <IMAGE>

Abstract: An encoder encodes a plurality of bit sequences of a digital signal into data codewords having improved signal characteristics, i.e., limited maximum run lengths and limited cumulative DC-offsets. Then, the encoder performs error protection encoding on the data codewords using a forward error correction ("FEC") code to form an FEC code block from a number of the data codewords. Preferably, the FEC code block is formed by generating a number of check or FEC bits equal to the number of data codewords in the block, and then concatenating one FEC bit and its binary complement with each data codeword so that one FEC bit and its complement are interposed between each successive codeword. In a preferred embodiment, a 96-bit FEC code block is formed from eight 10-bit data oodewords (formed by an 8b/10b data encoder), eight FEC bits, and eight FEC complement bits. In another preferred embodiment, each 16-bit input sequence (DATA 0, DATA 1) is encoded into a 20-bit data codeword pair made up of a 9-bit codeword and an 11-bit codeword. An implementation of this embodiment uses a precoder and 8b/9b and 10b/11b sub-encoders, which collectively perform 16b/20b encoding. Then, an 8-bit FEC word is generated from an 80-bit block consisting of four of the 20-bit codeword pairs. One FEC bit and its binary complement are concatenated to each 9-bit and 11-bit data codeword, resulting in a 96-bit FEC block. Preferably, the data codewords in the FEC blocks are 3/4/3 codewords. Also, the complementary FEC bit pairs can be used at the receiver to obtain proper framing of the FEC code block prior to decoding.
