Abstract: In the preparation of a supported procatalyst intended for the polymerization of olefins, particles are formed of magnesium dihalide and alcohol. The particles are reacted with an organic compound of a metal from the groups I-III, and the resulting particulate product is activated by means of a titanium and/or vanadium compound and optionally a donor, and optionally a prepolymerization is carried out for the activated particles. A problem of such a method is how to form particles of magnesium dihalogenide and alcohol having a structure advantageous for the polymerization of olefins. The problem has in the present invention been solved so that the particles are formed by spray crystallizing (spray freezing) a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol. The hydroxyl content of the particles so obtained is much greater than earlier, which results in a much more active procatalyst than the preceding ones.

Abstract: A linear amplifier includes a feed forward circuit which is operative to eliminate distortion of the amplified signal by utilizing a second circuit path (103,115,117,122,124) parallel to the amplification path (101,105,110,113,119,127,130) to generate a distortion cancellation signal and combine it with the output of the amplification path to cancel the distortion. The gain and phase of the feed forward circuit is automatically adjusted by discrete steps through the operation of a stored program controller (140). The initial adjustment step is set at some minimum discrete value and its effect on the cancellation level of the feed forward circuit is evaluated. If the cancellation level does not change by a specified amount the adjustment step is increased by a discrete amount. Adjustment of the cancellation level is continued by discrete steps under control of the stored program control until a desired cancellation level is achieved. The number of step adjustments permitted is preset at some value. If the allotted number of step adjustments fails to achieve the desired response, the stored program control checks for the existence of possible fault conditions in the feed forward circuit.

Abstract: Image data compression is implemented by partitioning an image into relatively small blocks of pixels, matching each block to an orthogonal icon, and extracting attributes associated with the icon. A table of these orthogonal icons and attributes represents a data compressed image. Each block is processed separately from all other blocks. Orthogonal processing is used to preserve orthogonal features while attenuating non-orthogonal features. An optimum set of orthogonal icons and an optimum set of attributes for each icon further improves data compression and fidelity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a ribbon icon, a corner icon, and a spot icon. An optimal set of attributes includes average intensities, intensity transition position and separation, and angle of the principal axes.

Abstract: A process is described for the production of a dynamically loadable, crosslinkable composite material comprising an elastomer matrix with an embedded strengthening support layer of woven textile fabric. Before embedding in the elastomer matrix, the fabric is prepared using an aqueous dispersion of synthetic resin and latex and is dried. An adhesion-promoter layer of a crosslinkable, polar rubber in organic solution is applied to the dried fabric. The dried fabric provided with the adhesion-promoter layer is coated with a thin layer of rubber blend and embedded in the elastomer matrix. In order to produce a composite material which ensures good adhesion between the strengthening support layer and the elastomer matrix even under high flexural fatigue stress, an organic solution of toluene containing chlorosulphonated polyethylene (CSM) as crosslinkable, polar rubber is used to apply the adhesion-promoter layer.
