Filed: 1969-03-27
Abstract: 1,243,152. Digital transmission systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 March, 1969 [11 April, 1968], No. 16081/69. Heading H4P. In a binary data frequency shift receiving system in which the received shift frequencies are separated by band-pass filters which feed full-wave rectifiers whose outputs pass to threshold units which develop the demodulated binary signals, the rectifier outputs are also connected to a summing circuit which feeds further threshold units which give an output when noise in the transmission channel exceeds a certain level. In an embodiment the two rectifiers give binary signals in which Marks and Spaces are positive and zero and negative and zero respectively. When these signals are summed the resulting signal has zero amplitude except for a small positive or negative pulse at each bit transition, such pulses being less than the threshold levels. Noise results in a pulse which exceeds the threshold levels.

Abstract: 789,977. Furnace atmospheres. MINNEAPOLIS - HONEYWELL REGULATOR CO. June 1, 1954 [June 29, 1953], No. 16207/54. Class 51 (2). [Also in Group XXIX] Apparatus for controlling the composition of the hydrogen containing atmosphere of a heat-treating furnace 10 includes means 25 for measuring the heat treating potential of a heat treating constituent of the atmosphere, e.g. carbon, means 34 supplying a gas enriched with the heat treating constituent to the furnace, means 1 measuring the hydrogen concentration of the enriched gas, and means 37 controlling the supply of enriched gas in response to the measurement of the heat treating potential and the measurement of the hydrogen concentration. A basic neutral atmosphere is supplied through conduit 20 and a carburizing gas enriched in carbon, containing either carbon monoxide or methane or both, through conduit 34. A hydrogen partial pressure element 1 comprising a platinum or palladium tube gives a partial pressure output to recorder 4 and a total pressure output to recorder 5, while recorder 8 gives an output pressure proportional to the ratio of these pressures. The carbon potential element 25, taking the form of a fine iron wire whose electrical resistance varies with the carbon absorbed, is connected to an instrument 26 giving an output proportional to the carbon potential which may be fed to an instrument 27 for measuring the rate of change of the carbon potential. An instrument 23 having a manual setting means 30 gives an output pressure in conduit 29 proportional to the ratio of the rate of change of carbon potential to the amount of hydrogen in the enriched gas, and this output, together with a signal derived from a differential pressure sensing element 32 connected across an orifice plate 33 in the enriched gas line, is applied to an instrument 31 which produces an output pressure regulating the valve 37. The supply of basic atmosphere at 20 is controlled by a valve 19 in response to total pressure of the furnace atmosphere detected via element 12 and instrument 17. Instruments 15 and 21 respectively indicate the hydrogen partial pressure and the ratio of total to partial pressure. The furnace is electrically heated at 11. In a further embodiment, a programme controller replaces the manual means 30 and an output pressure from the instrument 21 regulates a valve controlling a basic atmosphere generator. Specification 568,204, [Group XIX], is referred to.
