Abstract: ABSTRACT OF THE DISCLOSURE: A method of incorporating glass fibres into thermoplastic plastics, in which the glass fibres are continuously mixed into molten thermoplastic plastic and the resulting mixture is moulded into a shaped product and optionally reduced in size. The method is characterised in that the glass fibres are preheated to a temperature below or approaching the fusion temperature of the plastic, the preheated glass fibres and the molten plastic are supplied separately to a premixing dome and are mixed therein, and the preliminary mixture thus obtained is continuously supplied directly to a two-stage degasification screw extruder for homo-genization. An apparatus is also disclosed for carrying out the above method, which includes a two-stage degasification screw extruder having a feed inlet and an outlet provided with an ex-trusion tool. The apparatus of the invention comprises a pre-mixing dome having a first inlet connected to a device for feed-ing preheated glass fibres, a second inlet connected to a fusion extruder for supplying molten thermoplastic plastic and an out-let opening directly into the feed inlet of the degasification screw extruder and mixing means in the premixing dome to effect a preliminary mixture of the preheated glass fibres and molten thermoplastic plastics. The invention enables one to carry out the incorporation of the glass fibres in the thermoplastics with as much care as possible, i.e. to avoid excessive breaking of the glass fibres and at the same time to reduce the mechanical abrasion, in particular as a result of the friction with the glass fibres, of the mixer parts concerned.

Abstract: CANADIAN ABRIDGEMENT     The invention principally concerns marine radar systems and seeks to reduce "sea clutter".  The radar transmitter is arranged to transmit a set of four pulses forming two pairs of pulses in which the pulses of a pair are time spaced by the radar interpulse period and frequency spaced by the reciprocal radar pulse length.  The pairs of pulses are frequency and time spaced by several times the frequency and time spacing of the two pulses in a pair.  Transmission takes place from a rotatable antenna which exhibits squint and the antenna is rotated at a rate which having regard to the squint effect and the time separation of the pulses is such that all of the four pulses irradiate the same areas in the plane of rotation of the antenna.  This renders possible signal processing in the radar receiver to achieve both frequency and time decorrelation of clutter.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a method for removal of excess of a liquid metal coating from a substrate, such as a hot dip coated metal substrate, and in preferred embodiments, for control of metal coating thickness.  The method involves moving the substrate through a stationary pulsating or alternating magnetic flux.  The flux is directed in a path which enters the coating at an entry zone and exits from the coating at an exit zone, those zones being on the external surface of the coating and spaced apart in the direction of advance of the substrate. The frequency and intensity of the flux are controlled so as to exert on the coating surface a force opposing the viscous drag forces exerted in the coating by the moving substrate. Apparatus for use in performing the method is described.
