Abstract: Arrangement for bridging expansion joints in carriageways, especially bridges Abstract of the Disclosure An arrangement for bridging expansion joints in carriageways, especially bridges.  One or more parallel plates run at right-angles to the direction of the carriageway adjacent at the top to the surface of the carriageway.  The plates are supported at the bottom on bars which run at right-angles to the expansion joint and transmit loads directly or indirectly into the edges of the joint adjacent thereto.  For controlling the spacing of the plates, control cables are provided.  The plates are connected to the cable runs of the control cables.          The cable runs run parallel to the bars and are attached either to the load-transmitting bars themselves or to separate control bars.

Abstract: ABSTRACT OF THE DISCLOSURE           Halides of alkali and alkaline earth metals ("metals") are reduced with gallium, indium or thallium ("reducing metals") at temperatures below their boiling points at vapour pressures at which the gaseous monohali-des of the reducing metals are formed.  The quantity of the reducing metals is chosen such that it is sufficient both for the reduction of the metal halides and for the simul-taneous solution of the metals formed, e.g.:            MgCl2(s)+2Ga(l) = ??(l)+2GaCl(g);    900°K, 0.02 torr.            The metal is distilled off from the melt formed and is con-densed; the metal-free reducing metal is recycled for the reduction of the metal halide.  The reducing metal is re-covered from the monohalide for reutilization in the halide reduction; this is effected by reduction of its oxide which is formed either by oxidation of the monohalide, or by oxi-dation of the trihalide resulting in the disproportionation of the monohalide in addition to elemental reducing metal.          The continuous process design, the loss-free recycling of the reducing metal, the utilisation of the heat of exother-mal processes, and a minimum consumption of electric power permit a high profitability of producing alkali and alkaline earth metals according to the invention.

Abstract: TITLE OF THE INVENTION    An Adaptive Digital Filter ABSTRACT OF THE DISCLOSURE    An adaptive digital filter has been found which can be used, in a prediction filter residing in an ADPCM modulator and an ADPCM demodulator, providing stable operation and minimum phase shift response.  The filter (Fig.4, Fig.5) has three parallel branches (A,B,C), two (A,B) of them have a plurality of series connected non-recursive filter elements (A1-An, B1-Bn) each of which has a degree not larger than three relating to an operator (Z-1) with the third branch (C) being merely a con-ductive line.  The tap coefficients (c1, c2, ....,d1, d2,...) of non-recursive filter elements change according to solutions of the transfer function of the filter.  A numerator and/or a denominator of the transfer function of the present filter is a Chebychev polynominal relating to an operator (Z-1), and has a zero point and/or a pole. The solutions (wi, vi) of a numerator and a denominator are located alternatively on a unit circle (Fig. 6) in the Z-1 plane.  When the solutions of the transfer function do not locate alternatively on said unit circle, tap coefficients (c1, c2, ...., d1, d2....) are not updated  since non-alternate solutions do not assure the stable operation and/or minimum phase shift response of the filter.

Abstract: Abstract A mobile target system where anti-armour weapons training is disclosed.  The target system includes a driverless, self-propelled tractor vehicle on relatively low profile and a low prorile, wide track trailer with a long drawbar articulately connected to the tractor.  Projectile targets are carried by the trailer.  The control for the tractor controls the vehicle to drive along a selected path.  This may include a ground wire that the tractor follows and a radio control unit for initiating an excursion of the target along the path.  The separation of the traction and the target stability functions allows the use of a relatively small, easily steered tractor vehicle, while the target carrying trailer may be a relatively easily steered single axle trailer with a high stability wide track.  Separation of the target from the tractor provides some modest protection for the tractor.

An approximately 0.25 to 4 percent molar excess of aromatic hydroxyl monomer and/or aromatic amine monomer and/or an esterified and/or amidated derivative thereof is provided in the polymerization zone during the polymerization reaction.
