Abstract: 440,826. Reproducing opaque originals by contact printing. NAAMLOOZE VENNOOTSCHAP CHEMISCHE FABRIEK L. VAN DER GRINTEN, Venlo, Limburg, Holland. Aug. 10, 1934, No. 23196 Convention date, Aug. 11, 1933. Drawings to Specification. [Class 98 (ii)] An original is covered with a sensitive sheet and a dividing screen combined with a covering screen is placed on the sensitive sheet and the combination illuminated, the light passing in turn through the dividing screen, the covering screen and the sensitive sheet. The dividing screen may comprise a lenticular or a prism screen made of glass, quartz, celluloid, cellulose, cellulose derivatives or gelatine. The covering screens may be made by providing the back of the lenticular or prism screens with sensitive layers such as a mixture of paradiazodimethylmetatoluidine chloride and resorcinol, a silver bromide emulsion, or a chromate gelatine layer and exposing through the lenticular or prismatic side of the screen. The lenticular screen may comprise a system of two crossed cylindrical lenticular screens. The chromate gelatine covering screen may be silvered or nickelled after preparation. In the reproduction of the original using the combination of screens, a band-like source of radiation may be employed, and the original, sensitive sheet and the screen combination may have the form of a circular cylinder or may be moved in the surface of a circular cylinder. A pointlike source of radiation may be moved in a straight line parallel to the lines of the screens. Specifications 425,186 and 440,868 are referred to.

Electrical roll condensers of the kind comprising a pair of metallized tapes of dielectric material each having a folded-in edge portion disposed at opposite ends of the condenser are wound by advancing a tape of dielectric material metallized on one face, folding in an edge portion of the tape, winding the tape into a supply roll containing a length of tape sufficient for a large number of condensers, and re-winding the tape together with a similar tape into a plurality of condenser rolls. As shown, two superimposed tapes 1, 2 having metallic coatings 3, 4 have folded-in edge portions. The coating at the curved outside edges may be re-inforced by a further coating applied by condensation of a metallic vapour at sub-atmospheric pressure. In a modification, the two similar tapes are superimposed one on the other before being wound into a supply roll. In a further modification, two pairs of tapes may form the condenser, one pair of tapes being metallized, while the other pair is non- metallized, one non-metallized tape being interposed between the metallized tapes.

Abstract: 1,146,287. Impedance matching. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 27 April, 1966 [1 June, 1965], No. 23361/65. Heading H1W. The probe 1 extends from a base 2 which forms with the interior of inner conductor 7 a short length of transmission line serving to transform the impedance of the end-face 5 of the base into a short circuit in the plane B. The dimensions of the probe and base are such that, as the probe is moved within the waveguide 13, the inductance and capacitance presented to the guide by the probe and base are mutually cancelled and a substantially pure resistive load is presented to the waveguide. The probe couples the waveguide to a coaxial line 10 via an elbow 8. Energy leaking past the base 2 propagates within conductor 7 and is attenuated by a coolant liquid which is fed through a tube 4 into a recess 5 in the base 2 and returns along the cylindrical space between tub s 3, 4.

Abstract: 244,552. Western Electric Co., Ltd., (Western Electric Co., hic.). Oct. 11, 1924. Addition to 243,088. Thermionic generators, amplifiers, and modulating systems.-In order to obtain an equal distribution of the load upon the tubes for all frequencies, and to prevent inter-tube '' singing," the various tubes in a combined high-power amplifying and modulating installation, are arranged in a symmetrical disposition with reference to the input and output circuits. As shown in Fig. 1 the power amplifiers 30, fed in parallel from a source 26, are arranged four at the vertices of a rectangle and the fifth at a point in line with one of the sides. The grid bus bar 41 forming the common input is substantially U-shaped, as are the filament supply leads 29, 31 fed by a source 17. The modulator tubes 20 are similarly arranged, the input from the microphone 11 being connected across the common grid bus-bar 40 and the filament supply. The common plate current is taken from a generator 18 through a choke 21 which contains a constant current supply. Inductance coils 24 and 36 are included in the plate circuit of each of the tubes to prevent " singing," as described in Specification 217,552. Similarly, a choke 22 prevents hgih-frequency oscillations in the output from the amplifiers 30 from being impressed upon the plates of the modulators 20. Fig. 2 shows an alternative arrangement in which six power amplifiers 30 are associated with six modulators 20. Here the grid bus-bars 40 and 31 respectively are in the form of a closed ring, and also one lead 27, 29 respectively of each filament supply, the other filament lead being arranged symmetrically as shown. Fuses 44, 47 and jacks 45, 48 are also inserted in each plate circuit to protect the tube' and to enable the insertion of an ammeter respectively. The plate supply is tapped off central bus-bars 25 and 37 from a common source 18. The filaments are fed in parallel from an alternator 17.
