Abstract: A polymer capable of forming an anisotropic melt characterised in that the polymer chain includes residues of cross-linking reactants at a concentration sufficient to give a polymer with a melt viscosity of not greater than 10<sup>7</sup> Nsec/m<sup>2</sup> measured by capillary rheometry at a shear rate of 10' N/m<sup>2</sup>. The polymers exhibit favourable shear dependent viscosity characteristics in that the viscosity is high under low shear conditions and is low under high shear conditions, as judged by the viscosity characteristics of polymers of the same composition but not containing the residues of cross-linking reactants.

Granted: 1988-10-13
Abstract: The device includes two driving circuit (C1, C2) each of which includes six power transistors (T11-T16, T21-T26) that are connected in pairs into three parallel circuit branches. A first coil (B11) of one of the motors and a first coil (B21) of the other are, on the one hand, both connected to the junctions of the transistors of one of the branches of one of the driving circuits (C1) and, on the other hand, respectively connected to the junctions of the transistors of the two other branches of this circuit. The same applies for the second coils (B12, B22) of the motors and the other driving circuit (C2). The various transistors are controlled so that the two coils of the same motor simultaneously receive the current pulses which are needed to make it turn but by preventing the simultaneous application of current pulses to a coil from one of the motors and to a coil from the other. This arrangement makes it possible to save four transistors and two output terminals on the integrated circuit used to control the motors.

Abstract: The present invention refers to a method for controlling the vertical adjustment of a levelling and compacting plank drawn by a road-construction machine. During the working procedure the level of the plank, which is in floating contact with the material, is adjusted automatically. The present invention aims at preventing undesirable lifting of the plank caused by material which is located ahead of the plank and the flowability of which was changed due to an interruption in the motion of the machine. Hence, the invention employs the feature that, when the travelling mechanism is switched on, lifting of the plank, which is blocked against lowering when the machine is standing still, is blocked as well and that the blocking is eliminated only after a predetermined period of time.
