Title: Improvements relating to Structural Units.
IPC: D04H3/16
Filed: 1967-05-03
Abstract: A structural unit, e.g. for use in walls or partitions, comprises one or more sheets formed of molecularly oriented organic continuous filaments arranged at random in a non-parallel manner throughout the or each sheet, the sheet or sheets being impregnated with a thermosetting resin. The filaments may be of polyethylene terephthalate, isotactic polypropylene, polycaproamide, polyhexamethylene adipamide, PVC, polyvinylidene chloride, cellulose acetate, polyacrylonitrile or polyvinyl alcohol and the impregnating resin may be a phenoplast or aminoplast. In one method of making the sheets, polyethylene terephthalate is extruded as filaments from a spinneret and advanced by means of a drawing injector nozzle supplied with compressed air, the filaments being cooled during such advance. The bundle of filaments so formed is fed via a reciprocating guide on to a conveyer belt to form a non- woven sheet, which sheet is passed between heated calender rolls to bond the filaments where they cross. Two sheets formed as described, i.e. " spunbonded," are superposed and needled before impregnation with a solution of phenolformaldehyde resin in a mixture of alcohols. The impregnated sheet is allowed to dry, then dried under heat at one temperature before heating at a higher temperature to cure the resin. The resulting sheets are sound insulating, rot resistant and fireproof. In a second embodiment a structural unit comprises a core of rigid polyurethane foamed in situ between two of the impregnated sheets. An alternative unit comprises an undulating one of said sheets between two plane said sheets.

Filed: 1968-10-18
Abstract: A combined amplifier and mixer or separator comprises a field effect transistor 12 (Fig. 2) having a low voltage rating and high gainbandwidth product having its source-drain path in series with the emitter collector path of a bipolar transistor 20 having a high voltage rating and dissipation whereby transistor 20 provides across its load a voltage swing larger than the rating of the F.E.T. The circuit shown is used for the video stage of a television receiver, the sound carrier being selected by a timed circuit 45, 46 and the video signal being passed by way of series and shunt peaking chokes 23, 25 to the C.R. tube 41. In Fig. 3 the circuit is used to amplify the R-Y, B-Y and G-Y and Y signals in a colour television receiver and to mix the colour signals with the Y signal. The Y signal is applied at 51 to a preamplifier FET 50 having a negative feedback gain control 53 and a brightness control 57 which varies the voltage on a second gate, the control voltage being obtained from a horizontal scanning pulse H. The output is derived via a peaking and matching circuit 60- 64 via a delay line 52 and matching circuit 70, 73 and is applied to the gates of F.E.T.'s 75, 76 and 77. The R-Y and B-Y signals are supplied to F.E.T.'s 95 and 99 connected in parallel with 75 and 77 to effect mixing. The R-G signal is derived from the outputs of 95 and 99 and applied to an F.E.T. 106 in parallel with 76 to effect mixing, feedback through resistor 102 effecting correction of the signal. The outputs from the parallel pairs of F.E.T.'s are fed to three bipolar transistors 90-100 to form series circuits basically of the Fig. 2 type. The R, Y and G signals are fed to the CR tube via peaking circuits such as 91, 92, diode 132 serving to protect the gating circuit. It is suggested that the mixing with the luminescence signal could alternatively be effected at the CR tube control electrode.
