Title: Improvements in or relating to silica-magnesia catalyst for hydrocarbon-oil conversion
IPC: B01J21/14
Filed: 1951-04-10
Abstract: A catalyst, particularly for hydrocarbon conversion consists of up to 25 per cent. of MgO, dry basis, in the form of catalytically active magnesium silicate and is prepared by mixing a magnesia-affording substance with reactive silicia, converting the mixture to magnesium silicate and free silica, drying the mixture and deactivating uncombined silica contained therein.  The silica may be in the form of a hydrogel, hydrosol or xerogel and the magnesia may be added as calcined magnesite, magnesium hydroxide or as a soluble salt precipitated by a base.  The presence of alumina is avoided.  After comingling the silica and magnesia the mixture may be digested for 2-100 hours at 120-300 DEG  F. to form magnesium silicate (3MgO.4SiO2. H2O) and the deactivation of the excess silica may be effected by culmination at 800-1400 DEG  F. for 2-24 hours in steam. Alternatively the mixed silica and magnesia may be digested for 2-100 hours at 120-300 DEG  F. with an aqueous solution of ammonia or a water soluble amine.  The MgO content is preferably between 10 and 25 per cent.  The catalyst may be used in hydrocarbon cracking processes at 80-950 DEG  F. and 1-5 atmospheres absolute pressure, or for reforming gasoline at 900-1025 DEG  F., pressures of 5-25 atmospheres absolute and liquid space velocities of 0.1 to 2 V / V / hour, in the prescent of hydrogen. p

Title: Improvements relating to the coupling of electromagnetic energy
IPC: H01P1/32
Filed: 1956-03-16
Abstract: 834,412. Waveguide directional couplers. GENERAL ELECTRIC CO. March 16, 1956 [March 17, 1955], No. 8322/56. Class 40 (8). A non-reciprocal directional coupler comprises a magnetically-polarized member of ferromagnetic material, e.g. nickel-zinc ferrite, extending between a pair of wave transmission lines and coupled to at least one of the lines in a region where the magnetic component of the wave is circularly polarized. As shown in Fig. 4, rectangular guides 23, 24 are coupled by a ferrite member 26 situated at a distance X0 from the narrow sides of guides where the magnetic field of the H10 mode has a circularlypolarized component which rotates in a plane parallel to the broad face of the guide. By choosing a particular value of polarizing field H0 applied at right-angles to the rotation r.f. field the gyromagnetic resonance frequency of the ferrite may be made equal to the frequency of the propagated energy under conditions of resonance transfer of energy through the ferrite takes place for only one particular sense of rotation of the microwave field vector. For the opposite sense of rotation the energy is absorbed. Since the sense of rotation of the vector is determined by the direction of propagation of the energy, coupling is effected for one direction of propagation only. Thus energy will be coupled from terminal A to terminal D but not from B to C. Hence, if terminal B is terminated by a reflective load no energy reflected at B towards A is coupled into the guide 23. Reversal of the direction of coupling may be effected by reversing the direction of the polarizing field H0. Since the degree of coupling depends upon the strength of the field H0 a variation in the field may be used to produce amplitude modulation of the coupled energy. A number of ferrite coupling elements spaced apart in the direction of the longitudinal axis of the guide may be used. The invention may be applied to circular waveguides transmitting energy in the H10 mode. An application to a measuring circuit (Fig. 7, not shown) is described. In this circuit the reversible directional coupler is used to switch energy in turn to a known and an unknown load.

Abstract: 678,584. Frequency and phase modulation. SOC. FRANCAISE RADIO-ELECTRIQUE. April 5, 1950 [April 20, 1949], No. 8593/50. Class 40 (v). A sinusoidally frequency modulated wave fs is converted to a different mean frequency and frequency deviation by applying it to one end of an unmatched delay line producing a T delay - where it is frequency changed by a 2 rectifier 5 across a circuit 6 tuned to an applied heterodyne frequency fh and after reflection and return to the input end of the line frequency changed again by the incoming wave and rectifier 3 to produce across a wide-band tuned output circuit 4 an F.M. wave of maen frequency 2fs - fn whose frequency deviation now is where F = #/2# is the modulation frequency, i.e. the modulation index has been multiplied by 2 cos ##/2 = 2 cos #F#. The end of the line 2 may be matched to the modulator 5, 6 by a quarter-wave line, and a filter excluding unwanted frequency may be included in series with or in the line. The system may be embodied in a receiver for a 100-channel multiplex phase modulated wave having the modulation frequencies transposed to a band 100-500 Kc/s, and in which the frequency deviation is therefore proportionately greater for the higher than the lower transposed frequencies. The delay line system approximately reduces the I.F. frequency deviation to a range having a frequency deviation about Œ200 Kc/s. for all channels before application to the discriminator so that distortion due to unequal frequency deviation " loading " of the latter is avoided.

Title: Improvements in or relating to recording the relationship of one physical quantity with another
IPC: G01D9/38
Filed: 1959-03-13
Abstract: 935,085. Recording-apparatus. W. G. BIRD. June 13, 1960 [March 13, 1959], No. 8686/59. Class 106 (4). In apparatus for recording the relationship of one physical quantity with another, e.g. the position of the pointer 2 of an ammeter 1 in relation to time, the record sheet 4, provided with sprocket holes to engage with rollers 5, 6 is wound on to a spool 9 driven at constant speed by clockwork or a synchronous motor and passes between a plate 14 and the rounded edges of a plurality of parallel laminations 12. The laminations 12, each of the shape shown, are mounted on a shaft and insulated from one another. Thin-pointed ends lie along an arc of a circle having a radius one and a half times the distance of the centre of the arc from the axis of rotation of the pointer 2. It is stated that this arrangement produces a substantially linear relationship between the angular movement of the pointer 2 and the transverse position of the corresponding mark on the record sheet. The position of the pointer 2 is recorded by passing an electrical discharge from a strip 61 through the pointer 2 and the lamination 12 which is immediately opposite it at that moment, through the lamination and thence through the recording sheet to the plate 14. The paper is marked electrolytically by the passage of a current or may be punctured by the passage of a spark. The discharges may be continuous or periodic. The apparatus may be used to record pressure, temperature or electrical voltage in relation to time. In a second embodiment, Fig. 5, for recording elapsed time, e.g. in echo-sounding, the indicator is constituted by a helical wire 34 located in a fine groove cut in a rotating hollow cylinder 33 formed rotating hollow cylinder 33 formed of insulating material. The laminations 30, in the form of elongated parallelograms are slightly spaced from the surface of the cylinder. In this case an electrical pulse is applied to the helical wire when a sounding pulse is created and a further pulse applied to the wire when the echo is received. Thus, marks are produced on the graph paper representing the depth or altitude being measured. Various arrangements of the helical wires are described to enable measurements in different ranges or on different scales to be made. The cylinder may be rotated uniformly or may be driven in relation to the speed of the strip carrying the echo-sounding apparatus.
