Title: Improvements in or relating to the maintenance of urinals, water-closet basins and the like conveniences
Inventor: MAUDE EDWARD
IPC: E03D9/00
Filed: 1963-05-28
Abstract: 1,069,213. Disinfecting closets &c. CALMIC Ltd. May 13, 1964 [May 28, 1963], No. 21196/63. Heading A5G. [Also in Division El] A method of maintaining a flushed convenience such as urinals and water-closet basins in a sanitary condition comprises forming, between flushes, a concentrated aqueous disinfectant solution from a viscous slowly mobile disinfectant composition, and diluting the solution during a flush before discharging it into the convenience at the end of the flush. The composition may be a paste, emulsion or jelly and may incorporate a bactericide and a detergent, one of which is in solid form. It may contain about 50 per cent of a solid quarternary ammonium compound dispersed in a liquid detergent compatible with it and in a concentration of 35 to 40 per cent. The dispersion may be diluted with a liquid, e.g. propylene glycol to give it the appropriate viscosity. The composition may comprise a liquid detergent and a liquid bactericide and may then include a water-soluble thickening agent, filler or like substance. The bactericide may comprise a suitable phenolic derivative. The diluted solution finally discharged into the convenience contains 2 to 15 parts per million of ammonium compound. The concentrated aqueous solution may contain approximately 2 per cent of the amonium compound and may be formed by holding the composition in contact with one face of a layer, wad or plug of a network or perforated material, e.g. sponge, the opposite face thereof contacting a quantity of still water. A device to carry out the method comprises an outer container 1 having a pipe connection 10 at its base to feed water thereto from a flushing system during a flush and to return it into the convenience at the end; an inner container 20 for the composition open at its lower end and spaced above the base of the container and closed by a layer of sponge 22, on the upper face of which the composition can rest; and a baffle or weir, e.g. a projection 13 of the connection 10, between the countairier 1 and the pipe connection 10 to retain a quantity of water beneath the container 20 in contact with or to submerge the lower face of the sponge. The container 1 may have a compartment 4, having a pad 28 on the back 29 dipped in deodorant therein from which a draught emerges as the result of displacement of air from the container 1 by the ingress of water during a flush. A float 17 connected by a stem 16 to a valve 15 ensures that the water does not rise too high. The compartment 4 is closed by a grille 5 and in it is a tube 30 communicating at one end with the container interior and terminating at the other end 31, having holes 32, behind the grille 5.

Abstract: 889,841. Cathode-ray tube circuits. FERNSEH G.m.b.H. June 22, 1959 [June 20, 1958], No. 21315/59. Class 40(7). In a three-beam shadow-mask cathode ray colour reproducing tube the deflection correction magnets 13, 14 (Fig. 7) for the two beams which are not in the vertical plane of symmetry have supplied thereto, in addition to the normal correction currents from generators G, R, further correction currents derived from voltages produced by modulating in circuits 5, 6 respectively, a frame frequency sawtooth voltage 7 by a parabolic, line frequency, voltage 8 and a line frequency sawtooth voltage 9. The output of modulator 5 comprising the waveform 10 is supplied, via amplifier 11 and transformer 12, in anti-phase to the generators G, R resulting in currents, additional to the normal correction currents, of the form shown in Fig. 4. By adjusting the normal correction currents so that, instead of having errorfree positions along vertical and horizontal central lines as shown in Fig. 1. (the lines 1, 1<SP>1</SP>, 2, 2<SP>1</SP> and 3, 3<SP>1</SP> of which show the green, blue and red raster lines respectively), such positions occur at the upper margin, as shown in Fig. 2, the additional correction currents (Fig. 4) reduce the registration errors at the lower edge to the same small amount present at the centre. The remaining errors (parallelogram errors), i.e. at the side edges where, as shown in Fig. 5, the ends of the lines of the green raster (broken lines) are skewed in relation to those of the red raster (full lines) are compensated by the output of modulator 6 (waveform 22) which is supplied to the generators G, R, via amplifier 15 and transformer 16 and gives rise to currents of the form shown in Fig. 6c. Suitable circuits for the modulators 5 and 6 are described in connection with Fig. 8 (not shown).

Abstract: 1,172,006. Producing rotating polarization. COMMISSARIAT A L'ENERGIE ATOMIQUE. 9 May, 1967 [11 May, 1966]. No. 21533/67. Heading H1W. A wave of continuously rotating polarization is produced by means of a bend in a circular waveguide. An H 11  wave propagating in bend 3, Fig. 5 (which extends in a plane perpendicular to the plane of the drawing), may in general be decomposed into two waves having directions of polarization respectively E and H. For the E component, the bend behaves as an E-plane bend and for the H component, as an H-plane bend. The components therefore suffer different phase-shifts and, in general, the result is an elliptically polarized wave at the output. If the bend is such that the phase difference amounts to #/2 and the input wave lies at an angle #/4 to E and H, the result is a circularly polarized wave. The direction of polarization of the incident wave may be varied by adjusting the angular position of a rectangular-to-circular transistion 4 which is joined to the bend 3 by a rotatable joint.

Title: Improvements in the catalytic destructive hydrogenation under pressure of solid carbonaceous materials
IPC: G09F21/06
Filed: 1934-07-24
Abstract: In the destructive hydrogenation of solid carbonaceous materials the catalyst is distributed in the initial material in the presence of so much water that a homogeneous paste is obtained from which the water is removed before the destructive hydrogenation.  Sufficient water is added that the paste contains 57--80 per cent by weight of water calculated on the solid material and oils may be added to the paste before the removal of the water.  The basic constituents of the coal are preferably neutralized by the addition of acids or acid salts. 100 kgs. of finely ground crude brown coal are mixed in a mixing worm with 32 kgs. of an aqueous solution containing 1100 gms. sulphuric acid and 13,6 gms. ammonium molybdate.  The paste is ground in a ball mill, with 50 kgs. heavy oil and then heated to 140 DEG  C. in a stirring vessel provided with steam coils whereby the water is removed.  The dry paste is subjected to destructive hydrogenation and 97 per cent of the coal is converted into an oil containing only 4,2 per cent asphalt.  Catalysts comprising the oxides, hydroxides, sulphides, halides or carbonates of the metals of Groups 3--8 may be used in colloidal condition or they may be absorbed by the solid materials and then converted into colloidal condition.  Specification 332,246, [Class 32], is referred to.
