Abstract: 1445311 Detecting overheating axle boxes SERVO CORP OF AMERICA 7 Jan 1975 [6 March 1974] 645/75 Heading B7H In a system for detecting overheated axle boxes on: railway vehicles in: which a pair of heat detectors, one on each side of a track, scan the axle boxes of opposite wheels of each passing axle and. in which each detector output signal, proportional to axle box temperature, is compared with a series of voltages representing absolute temperature values and in which the difference between the detector output signals is compared with a further series of voltages representing axle box difference temperature values, a multiplex arrangement is provided to reduce the number of comparators required.. Inputs from the detectors associated with rail 1 and. rail 2 are applied on lines 12, 14 to multiplex switch 10 which is activated by a free running multivibrator 32. The switch output is applied to the inputs of differential amplifier 36 which provides in the first position of the switch an output which is a function of the difference between the signals (rail 1 - rail 2) and in the other position of the switch the opposite difference (rail 2-rail 1). The output of the amplifier 26 is applied as one input to a second differential amplifier 38. In addition the individual detector signals are applied in turn via the switch to one input of a third differential amplifier 64. The output of the multivibrator 32 is also connected to a "divide by two" circuit 54 which supplies control signals at half the multivibrator frequency on lines 58 and 60 to control second and third multiplex switches. 40, 66 such that during a first, and subsequently odd, complete cycles of switch 10 the two differences are compared in turn in amplifier 38 with a "warm" difference voltage level provided via switch 40 and the two individual detector signals are compared in amplifier 64 with a "warm" absolute value level provided by switch 66, and during the second, and subsequent even, complete cycles of switch 10 the two difference voltages are compared in turn with a "hot" difference voltage level supplied via switch 40 and the two individual signals are compared in turn with a "hot" absolute voltage level supplied via switch 66. Demultiplexing logic 80 including AND gates controlled by the multivibrator signals and by the divide by two circuit output signals derive alarm signals on lines 102, 104, 106 and 108 from the outputs of the differential amplifiers. In a second arrangement the "hot" and "warm" levels provided via the switches 40, 66 are replaced by hot signals associated respectively with friction and roller bearings and the divide by two circuit is replaced by a circuit which discriminates the type of bearing.

Abstract: 524,986. Gas washing processes. UNIVERSAL OIL PRODUCTS CO. Jan. 10, 1939, No. 856. Convention date, May 31, 1938. Drawings to Specification. [Class 55 (ii)] [Also in Group IV] Hydrocarbon mixtures containing three and/ or four carbon atom olefines and derived from the cracking of petroleum oils are purified by washing in the liquid phase with water to remove basic impurities and with aqueous alkali for the removal of acidic impurities. Sulphur and nitrogen compounds are thereby removed which would otherwise have a poisoning effect upon the catalysts, particularly those containing phosphoric acid, employed for the subsequent polymerization of the olefines. The treatment of cracking plant receiver gases to give a purified butane-butylene fraction suitable for polymerization is described. The gases are passed to a high-pressure absorber in which all four carbon atom hydrocarbons and a major portion of the three carbon atom hydrocarbons are absorbed in debutanised naphtha; the product is then mixed with unstabilised cracked gasoline and after heating, passes to a depropaniser in which propane and lighter gases are removed; the bottoms from the depropanizer containing the butanes and butylenes are cooled and treated with an aqueous alkaline solution, usually caustic soda, and then subjected to fractionation in a debutanizer to a butanebutylene distillate which is washed first with a stream of water, preferably slightly acidulated, and finally with aqueous alkali. The unabsorbed gaseous products from the high - pressure absorber are subjected to further absorption in a low-pressure absorber wherein the absorber oil is an intermediate fraction of cracked naphtha which is returned to the cracking plant fractionator.
