Abstract: The present invention relates to a solid catalyst suitable for polymerising olefins in a heterogeneous process, the catalyst being obtainable by a process comprising in a first stage contacting an electron-donor D2 containing labile hydrogen, e.g. alcohol, with a spheroidal MgCl2 support containing an electron-donor D1 free from labile hydrogen, e.g. ether, and in a second stage contacting the resulting support with a zirconium metallocene, at least one titanium or vanadium halide and optionally with an organoaluminium compound, preferably an aluminoxane. The solid catalyst may be used as such or in the form of a prepolymer in a polymerisation of olefins, the prepolymer being obtained by contacting the solid catalyst with ethylene or a mixture of ethylene with C3 to C8 alpha-olefin in the presence of an organo-aluminium compound, preferably an aluminoxane. The solid catalysts and the prepolymer consist of spheroidal particles preferably having a narrow particle size distribution. <IMAGE>

Abstract: An apparatus for discriminating information signals from noise signals within a communication signal. The preferred embodiment comprises a first signal level detector, a second signal level detector, and a comparing circuit. Each of the signal level detectors comprises a digital low pass filter which employs a comparator for comparing current signal samples with previous samples and generating a representative comparator output. Each low pass filter has an attack time and a decay time, each of which characteristics is determined by an operational coefficient, the coefficient being responsive to the comparator output. The first signal level detector receives the communications signal as an input and generates a detection signal as an output; the second signal level detector receives the detection signal as an input and generates a noise detection signal as an output. The comparing circuit compares the detection signal and the noise detection signal and produces a speech burst detection signal. The operational coefficient is valued in the first signal level detector to establish a fast attack time and a slow decay time, and the coefficient is valued in the second signal level detector to establish a slow attack time and a fast decay time.

Abstract: An at least partially spent Zn-alkali slurry for use in zinc-air batteries is, after optional dilution with aqueous Group Ia metal hydroxide(s) and water, regenerated by: (i) optionally separating the dissolved and undissolved phases; (ii) electrolyzing the at least partially spent slurry and/or the separated dissolved phase from step (i), in a cell with a corrosion-resistant anode and a non-Zn-adherent cathode such that the Zn which deposits thereon self-detaches or is removable by a method selected from brushing, scraping, vibrating and the use of liquid jets, until no more than a preselected amount of Zn remains in the solution, the current density at the cathode being preselected so that in conjunction with the non-Zn-adherent characteristic of the cathode, the electrowon Zn will have, after consolidating into particles, a density of 0.2-2.0 g./cc and a surface area of 0.5-6.0 m<2>/g.; (iii) removing Zn from the cathode and consolidating it into particles; (iv) combining Zn from step (iii) with additional aqueous Group Ia metal hydroxide, and if desired other makeup components such as the optionally separated undissolved phase from step (i), thereby reconstituting charged slurry; (v) optionally analyzing the reconstituted slurry from step (iv) in order to ascertain whether at least the amounts of Zn (and of other constituents of the slurry) and the amount and concentration of the Group Ia metal hydroxide(s), lie within predetermined limits; (vi) optionally adjusting the amounts of reconstituted slurry ingredients. The invention includes also a similar process for the preparation of a Zn-alkali slurry for use in batteries comprising particulate zinc.

Abstract: The apparatus serves for treating workpieces by means of a plasma torch in a gaseous, preferably in an inert gaseous atmosphere. For this purpose, there is provided a gas-tight container and, in the interior of the container, a plasma gun as well as a cooling member for cooling the treated workpiece by a gaseous cooling medium stream. The cooling medium is a gas circulating in a closed circuit. Thus, the cooling gas can continuously used because heat is removed from the gas in a heat exchanger. A cooling operation can be realized in this way in temperature regions which are much higher than if liquefied gas is used.

Abstract: A device is described for producing hollow and solid mouldings from plastic by rotation casting, in which device an electroplated mould in the form of a double-walled hollow body (1) is heated and cooled by means of a heating and cooling medium respectively. A box (26), which contains plastics material, can be placed on the mould (1). The mould (1) and the box (26) can be jointly pivoted, so that the plastics material can run into the mould (1) and fuse on the mould wall. The double-walled hollow body (1) has a plurality of inlet and outlet openings (14, 15), for the heating and cooling medium, on its rear wall (7) directed away from the shaping inner contour (6), so that the heating and cooling can each be carried out selectively and quickly. The overall outlet cross section is greater than the overall inlet cross section, so that the hollow body (1) remains substantially unpressurised. The mould can simultaneously execute a rotation (28) about an axis, a pivot movement (5) about a second axis and translatory movements (20) in the direction of the axis of rotation in a freely programmable manner.

Abstract: A low-recoil firearm (10) is proposed, especially a compressed-air weapon or a hand firearm, comprising a stock assembly (25) and a barrel assembly (20) which can be displaced relative to the stock assembly (25) in the longitudinal direction (B) of the firearm (10). In the event of firing, the barrel assembly (20) can be moved counter to the firing direction (A) from a firing-readiness position. The recoil of the barrel assembly (20) caused by firing is constrained by a latching device (40) which can be overcome by the recoil energy of the barrel assembly (20). When the latching device (40) is overcome, work is carried out by the barrel assembly (20), which work is extracted from the recoil energy so that the recoil which is finally transmitted to the person firing the weapon is at least significantly reduced. In the case of the firearm according to the invention, the axial force required to overcome the latching device (40) is adjustable in the barrel longitudinal direction (B). <IMAGE>

Abstract: Molecular complexes can be used to target a gene encoding an immunogenic protein or polypeptide to a specific cell in vivo. The gene is incorporated into the target cell, expressed and the gene-encoded product is secreted and an immune response against the immunogenic protein or polypeptide is elicited. The molecular complex comprises an expressible gene encoding a desired immunogenic protein or polypeptide complexed with a carrier of a cell-specific binding agent and a gene-binding agent. The cell-specific binding agent is specific for a cellular surface structure which mediates internalization of ligands by endocytosis. An example is the asialoglycoprotein receptor of hepatocytes. The gene-binding agent is a compound such as a polycation which stably complexes the gene under extracellular conditions and releases the gene under intracellular conditions so that it can function within a cell. The molecular complex is stable and soluble in physiological fluids and can be used to elicit an immune response against a variety of immunogens in an organism for the purpose of vaccination or for the production of antibodies.
