Title: Dual fuel control system for a gas turbine kneading and mixing machine
IPC: F02C9/40
Filed: 1973-02-14
Abstract: 1425230 Automatic control of turbines GENERAL ELECTRIC CO 14 Feb 1973 [1 March 1972] 7234/73 Heading G3N [Also in Division F1] A dual fuel control system for a gas turbine, adapted to burn two fuels simultaneously, is arranged to give preference to a first fuel which is subject to varying availability. As shown, Fig. 1, a gas turbine 1, adapted to drive a vessel, is fuelled through nozzles 3 burning gaseous fuel from a manifold 4 or liquid fuel from supply pipes 5. The liquid fuel is supplied from a distillate oil tank 6 or a residual fuel tank 6 selected by a transfer valve 8. The selected liquid fuel is withdrawn through a stop-valve 9 by a shaftdriven pump 10 at a flow governed by a by-pass valve 12. The liquid fuel is fed to the pipes 5 through a flow divider 11 and monitored by a sonic wheel sensor 13, 14. The gaseous fuel is provided from the "boil off" in the spaces 20 above a LNG cargo in tanks 2.  The flow rate availability of the gas is primarily dependent on temperature and the gas is supplied under pressure to an accumulator 21 via a separately regulated cryogenic system 22. The gas in the accumulator 21 is passed through a filter 31 and a stop-valve 32 to a control valve 33 for the manifold 4, and is monitored by a pressure sensor 35. A regulator 30 within the system 22 is set so that the gas flow through the valve 33 is above sonic velocity, thereby ensuring that the stroke of the valve is proportional to the actual flow of gas through the valve. The position of the valve is sensed by a transducer 34. The solid-state analog dual fuel control system 36 receives a signal from a fuel command control 37 representative of turbine requirements and operates in a mode determined by a selector switch 38, a fuel ratio for one mode of operation being set by a selector 39.  The control system 36, Fig. 2, comprises a summer 40 comparing a gas-pressure set point signal with the actual pressure signal derived from the sensor 35 to provide an error signal which is applied to a proportional plus reset amplifier 41.

Title: Mechanically stabilized shapes of polystyrene and the like and method of producing such shapes
IPC: C08L27/00
Filed: 1944-04-19
Abstract: Mechanically stable articles of given shape made of polystyrene or like plastic material are produced by heating the shaped article to at least its transition temperature for a time less than permits unmoulding of the article and then cooling it at a rate less than that determined from formul  based on the shape of the article to give a finished article having a residual maximum tensile stress less than the tensile strength of the material forming the finished article.  The cooling rate m for (1) a rod of radius c cms. and (2) for a slab of thickness c/2 is determined from the formul <FORM:0595667/IV/1> <FORM:0595667/IV/2> where Sa is axial stress in lbs. per sq. in., a  is linear coefficient of expansion per degree Centrigrade, m is rate is temperature drop in degree per second, v is Poisson's Ratio, r is distance of point of stress from centre of rod, A is coefficient of diffusivity (for derivation of formul , see Journal of p  Franklin Institute, volume 190 (1920), pp. 597-631 and 835-870). The transition temperature is defined as the temperature at which internal stress is relieved and is for polystyrene 180 DEG  F. approximately (see "Transition Temperature and Cubical Expansion of Plastic Material," Industrial and Chemical Engineering, Sept., 1942, pp. 1052, et seq.).  In an example, an extruded polystyrene rod 1 inch diameter was heated in a liquid bath at 184 DEG  F. for 30 mins., cooled for 55 mins. at a temperature drop of 1/4 DEG  F. per min. to 170 DEG  F., for 20 mins. at 1/2 DEG  F. per min. to 160 DEG F., for 10 mins. at a drop of 1 DEG  F. per min. to 150 DEG  F. and finally cooled in air.  The sample on drilling and application of test liquids, e.g. kerosene, showed no sign of cracking.

Patent GB-1210625-A (GB)
Title: Improvements in or relating to teleprinter receivers
IPC: H04L25/40
Filed: 1969-02-11
Abstract: 1,210,625. Telegraphy. SIEMENS A.G. 11 Feb., 1969 [12 Feb., 1968], No. 7303/69. Heading H4P. A teleprinter receiver which can receive characters at selectable speeds includes a shift register to which each serial-bit character is passed. Stepping of the register is stopped for a period longer than one bit when the character fills the register so that the printer can operate during this period. Speed selection.-High frequency pulses are divided by a selected amount by bi-stables T1, T2, T3, the resulting signal passing to divider FT via bi-stable T4 to generate shift pulses ST. When operating at 100 Bd. T1 is by-passed and T2, T3 set to divide by 3. At 50 Bd. T1 is not by-passed, so dividion is by 6. At 75 Bd. T2, T3 are set to divide by 4, so T1-T3 divide by 8. Speed selection is by switch Gw. When the printer is used in local operation it operates at 100 Bd., and this speed is selected automatically by switch LK whatever the state of Gw so that the system reverts to the previously selected speed automatically when reverting to line operation. To reduce phase error in the pulses ST divider FT, which normally divides by 40, divides by 39 in its first cycle after reception of a Start bit. Normal operation.-5-bit Start-Stop signals from line L pass to the register KSp, KAn, K1-K5 under control of the shift pulses ST. When the Start bit reaches KAn, the output of KAn passes via gate G22 to prevent further shifting. Upon occurrence of the next pulse ST the state of KAn is read in to KSp, whose output passes to gate G16. Upon occurrence of the next pulse of pulse train ST2 (which has twice the frequency of ST1) G16 passes a pulse to bi-stable KL which develops a signal SLo to reset all stages of the register prior to reception of the next character. When the register is reset the output of G9 maintains KL generating SLo until a Start bit is received. Short Start suppression.-When a marking pulse arrives it passes via G15 to G17 to reset KL and end SLo, with consequent releasing of divider FT. When FT generates a first pulse ST2, which occurs a quarter bit period after the start of the Start bit, bi-stable KE is set to the current state of the line. If this state is spacing potential KE passes a signal to gate F10, resulting in renewed generation of SLo and so no stepping of the register in response to the short Start pulse. On the other hand, if the Start pulse lasts longer than “-bit period KE passes a Start signal via G15 to be read in to K5 irrespective of the state of the line at the instant of read-in.
