Abstract: 723,151. Aerial coupling arrangements; combined transmitting and receiving systems; duplex radio signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 22, 1953 [June 9, 1952], No. 14511/52. Class 40 (5). Two similar transmitter output stages T1, T2 are driven in phase quadrature and connected to a hybrid unit H through paths P1, P2, differing in length by an odd number of quarter wavelengths so that their outputs are in phase at one common output C of the hybrid unit connected to an aerial, and in phase opposition at another output R connected to a receiver or an absorber load. The hybrid unit may comprise lengths of coaxial cable dimensioned as shown and connected to form a rat-race, or a waveguide magic-T, or a centre-tapped transformer unit as shown in Fig. 2. Signal waves received by the aerial, or reflected back from it due to any mismatch of the transmitter feeder with the aerial, being in phase cannot pass direct to the receiver R or absorber load but first pass to and are reflected at the output stages T1, T2, and being then in anti-phase after return to the hybrid unit are directed to the receiver R or absorber load. The system suppresses ghost images in television transmission, or cross-talk due to reflection from an aerial in multiplex communication systems, and preserves the pulse shape in a pulsed radar or other system. Moreover, when R is a radar receiver, a T-R switch is unnecessary, or, if one is provided between the hybrid unit H and receiver R in a high-power system, only a fraction, say one tenth, of the transmitted power is used in energizing the T-R switch.

Abstract: 1,146,604. Radar; measuring radio wave velocity. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 1 April, 1966 [2 April, 1965; 16 April, 1965], No. 14618/66. Heading H4D. In a method of, and apparatus for, geophysical prospecting by electromagnetic waves of radio and infra-radio frequencies, the received echo may overlap the transmitted wave and to avoid the effect of the transmitted wave on the receiver the transmitted waves are cylindrical and the receiving aerial is a movable frame. In one embodiment the transmitting aerial comprises a top plate connected to the outer of a coaxial cable and a bottom plate connected to its inner conductor, the receiving system being two frame aerials connected in series and movable together (by remote-control) around the inner conductor; the whole aerial arrangement is in a device lowered into a bore-hole. For measuring the distance to a discontinuity (direction being determined by rotating the frame aerials for minimum signal) pulse radar with a cathode-ray tube display of two traces triggered simultaneously, one depicting the pulse transmitted and the other echo pulse, is utilized. Alternatively, an F.M.C.W. radar technique may be utilized, the beat frequency (proportional to range) being determined by a Lissajous figure method and the frequency sweep of the transmitted wave being non-linear to allow for variation of wave velocity with frequency; swept gain may be added to the receiver. The invention also comprises apparatus for measuring wave velocity in which the time for pulse transmission (at various frequencies) horizontally between known well points in a geological formation of interest is measured utilizing an oscilloscope synchronized by a pulse transmitted through the air, Fig. 5 (not shown). The transmitting aerial may be two in-line rods inserted subterraneously.

Title: Improvements in method of making sulphur trioxide
IPC: C01B17/79
Filed: 1930-05-13
Abstract: A catalyst for the manufacture of sulphur trioxide from sulphur dioxide and oxygen consists of a mixture of a vanadium and a caesium compound.  The amount of caesium in the mass may be increased until it is atomically three times that of the vanadium: a preferred composition is one in which the amounts of the two components are atomically equal.  According to an example, a carrier, such as celite chips calcined at about 1000 DEG  C., is immersed in an aqueous solution of ammonium metavanadate.  When saturated, the carrier is removed and dried at 110 DEG  C.  This operation is repeated until all the solution has been absorbed. An aqueous solution of caesium chloride is then applied by sprinkling, and after saturation, the carrier is again dried at 110 DEG  C.  It is preferable to heat the catalyst thus prepared to about 500 DEG  C. in an atmosphere containing sulphur dioxide before use.  Other soluble caesium and vanadium compounds may be used, together with salts such as caesium vanadate, and the solutions may be applied to the carrier either separately or mixed together. In the manufacture of sulphuric acid, the heat evolved in the converter is removed, so that the temperature of the gas in contact with the catalyst is about 420 DEG  C.
