Abstract: Procedure for fastening HSS-cutting edges (3) or the like to a tool support of metallic material, in particular the saw plate (2) of a circular saw blade (1) or the supporting band of a saw band for a band saw with the arrangement of intermediate pieces between support and cutting edges, in the course of which the HSS-cutting edges (3) are first of all in each case welded onto an intermediate piece (4) individually and in the soft or unhardened state, and then the intermediate piece (4) together with cutting edge (3) is heat-treated with age-hardening of the cutting edge (3) and at the same time hardening and tempering of the intermediate piece (4) in order to then weld the intermediate piece (4) together with cutting edge (3) onto the support (2). Tools produced according to a process of this type are thus distinguished by HSS-cutting edges (3) which are welded via an intermediate piece (4) onto a tool support (e.g. the saw plate 2) of a circular saw blade (1).

Abstract: An improved molded hinge assembly is disclosed and is particularly adapted for pivoted vehicle window applications. The assembly allows for the pivotal mounting of a vehicle window in a window opening in a vehicle body panel while requiring little or no bonding or other affixation of the window gasket or hinge assembly to the outer surface of the window panel. Furthermore, the present invention provides a molded hinge assembly that is relatively simple and inexpensive to manufacture and to install in a vehicle window application. Such a hinge assembly can also be manufactured by reaction injection molding techniques from multi-constituent materials, such as urethane, for example, which allows molding at relatively low pressures to prevent or minimize glass breakage and provides for secure bonding and sealing between the window gasket and the window panel.

Abstract: In order to enable the drawing-off of residual vapours of a low-boiling liquid from a pressure system (1) into a storage vessel (2), the pressure between said system and the storage vessel is first equalized, whereafter the presure in the storage vessel is reduced and the pressure in the pressure system increased, enabling thus passage of the low-­boiling liquid with its vapours in the liquid state into the storage vessel. This process can be repeated in order to draw-off liquid with its vapours from the pressure system.

Abstract: A previously isolated hepatitis B virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC) was used as a probe to clone the corresponding complemen­tary DNA from a human liver cDNA library. Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named  hap , is similar to that of the DNA-­binding hormone receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb  hap  mRNA species which is undetectable in normal adult and fetal livers, but pres­ent in all non-hepatic tissues analyzed. Low stringency hy­bridization experiments revealed the existence of  hap  related genes in the human genome. The cloned DNA sequence is useful in the preparation of pure  hap  protein and as a probe in the detec­tion and isolation of complementary DNA and RNA sequences. The  hap  protein is a retinoic acid (RA) receptor identified as RAR-β.

Abstract: A partition, more particularly for a corner shower, contains two door-elements mounted displaceably in an upper guide-rail. In the vicinity of the entrance, the upper guide-rail is curved like the edge of the tub and is connected to two lateral wall elements which are secured to the room and are flat. The purpose of the invention is to achieve reliable sealing and equally reliable guidance combined with a simple design. It is proposed that the guide-rail be curved over its entire length and comprise curved end-parts behind the flat wall-element. No lower guide-rail is provided. Instead, small narrow guide-elements are located outside the entrance.

Abstract: The invention relates to a digital distortion generator (pre- distortion or post-distortion generator) for the transmitting/receiving devices of a digital communication system with complex amplitude modulation. A distortion generator of this type, particularly as a pre-distortion generator when a digital pulse- shaping filter  disposed in front of it is used, is intended to permit effective compensation for the non-linearity of the transmission amplifier and other components and should at the same time be inexpensive to implement. For this purpose, the invention provides a device (6) for conversion of the signal location-indicating data I0 and Q0 of both channels from cartesian into polar coordinates a0 and  phi <9>0, and a memory (7), to which only the a0 quantity component of this data is supplied and which contains the distortion values (the difference between the ideal signal location and the distorted signal location) belonging to each addressed quantity, according to quantity and phase. These are added as correction values (distortion values) to the data a0 and phi 0, obtained from the I0 and Q0 data, of the signal location in polar coordinates. A device (10) is connected downstream for conversion of these pre-distorted or post-distorted values for the quantity and phase of the distorted signal location in polar coordinates into the distorted data for the I and Q channel into corresponding cartesian coordinates. <IMAGE>

Abstract: An arrangement in connection with a water bag (1) for a water mattress, comprising a mattress base (2) of a flexible material with a recess (3) in its top face for receiving water bag (1) which is designed with a flat top (1a) and a at least in filled condition downwards curved bottom (1b) consisting of two sheets (1a′, 1b′) which are joined by welding or glueing along their lateral edge portions. Said two joined sheets (1a′, 1b′) form a reinforcing framelike edge portion (4) around water bag (1) which is intended to sit in contact with the top face portions (2a) of mattress base around recess (3), thus, to reduce folding when there is a load on the water bag and to prevent ruptures due to fatigue and water leakage.
