Title: Improvements in or relating to radio receivers for use in television
IPC: H04B1/26
Filed: 1953-10-07
Abstract: 753,509. Radio receiving sets. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 7, 1953 [Oct. 10, 1952], No. 27543/53. Class 40 (5). In a superheterodyne radio receiver comprising means for switching the receiver to any one of a plurality of television channels and of wave ranges (e.g. for V.H.F. frequency-modulated sound broadcasting), the switching means so controls the connection of a variable condenser in the local-oscillator circuit that, when reception is taking place on one of the television channels operation of the condenser provides a fine tuning control, while when reception is taking place on one of the wave ranges operation of the condenser serves to tune the receiver to any one of a number of channels within the range. In the preferred embodiment the receiver, preferably employing turret tuning, is designed to receive on any one of a plurality of television channels within the frequency bands 44-67 Mc/s. and 174-216 Mc/s. and also to receive over two ranges within the V.H.F. band from 86.5 to 100 Mc/s. The receiver comprises the switched coils 1, 2 and 4, 5 in the aerial and R.F. amplifier circuits respectively and also a switched coil 11 in the circuit of the local oscillator valve 9. The coil 11 is tuned by a variable condenser 12 and a further fixed condenser 13. In television reception the condenser 13 in series with the condenser 12 restricts the effective tuning range of the latter which is then used as a fine-tuning control; for V.H.F. sound reception additional switch contacts on the switching means effect the closing of the switch 14, thereby short-circuiting the condenser 13 so that the condenser 12 provides an increased tuning range. In the circuit shown, valve 6 is the mixer and the coils 7, 8 comprise the first I.F. transformer.

Title: Improvements relating to the production of gases containing sulphur dioxide and sulphur trioxide
IPC: C01B17/76
Filed: 1951-11-30
Abstract: The working fluid of a gas turbine plant is heated indirectly in a heat exchanger by the heat set free in a plant for the production of gases containing sulphur dioxide by roasting sulphuric materials and of gases containing sulphur trioxide by catalytically oxidizing the roaster gas after purification and drying.  The source of heat may be the roasting plant, the sensible heat of the hot impure roaster gas or the sensible heat of the reaction gas leaving the catalytic plant. The working fluid is preferably compressed to about 4 to 10 atmospheres pressures and heated in 700 DEG C.  This fluid is heated to about 250 DEG C. by indirect heat exchange with the gases leaving the catalytic plant so that the surfaces in contact with the hot impure roaster gases cannot be over-cooled.  The turbine may drive a blower for compressing the working fluid together with blowers for the air and gas of the roaster plant.  The working fluid is preferably purified roaster gas in which case the turbine discharges into the catalytic and absorption plant and the temperature of the exhaust corresponds to the temperature at which the catalyst initiates the reaction.  If desired, the working fluid may be expanded to a lower temperature and then heated to the reaction temperature by the gases leaving the first reaction stage of the catalytic plant or by mixing with hot gas which is passed around the turbine.  In another arrangement, the gases are expanded to a temperature which is higher than the reaction temperature and cooled to the reaction temperature by cold air or roaster gas purified at low temperature.
