Title: Alarm apparatus
IPC: B64C13/00
Filed: 1977-05-26
Abstract: 1532344 Automatic control and alarm systems SPERRY RAND CORP 26 May 1977 [4 June 1976] 22206/77 Heading G3N A rudder control system includes a simulator with an integrator which provides a signal corresponding to the expected movement of a ships rudder and is compared with a signal derived from the actual movement of the rudder so that an alarm indication can be given if the result of the comparison exceeds a given threshold. The rudder in the particular application described is moved by hydraulic pistons whose individual pump rates are monitored by potentiometers 25, 27 in simulator circuit 19. Integrator 31 introduces a time lag corresponding to that present in the mechanical system so that an output signal which is an electrical analogue of the rudder motion is produced. The output signal is sealed and inverted at 33 and applied to amplifier 13 to give a closed loop. The simulated signal from sealing potentiometer 35 is compared with the actual rudder angle signal in comparator 39 and the output is applied to the threshold circuit 49, which may comprise a Schmitt trigger, and supplies alarm signals if the simulated and actual rudder angle signals differ by more than a predetermined amount.

Abstract: 479,691. Centrifugal separators. AKT.-GES. BROWN, BOVERI, & CIE. Aug. 14, 1936, No. 22480. Convention date, Aug. 16, 1935. [Class 23] Liquids and gases are separated from a mixture by centrifugal force, and the kinetic energy of the whirling mixture is utilized for bringing the separated liquid to a pressure higher than that prevailing at the entrance to the separator. The mixture is introduced tangentially by the inlet branch 1 to the casing 2 from which it passes to the passage way 3 and the cylindrical separating space 4. The length of the passage 3 is at least four times its minimum width. The mixture whirls in the space 4 and the separated gas or vapour passes upwards to the outlet 6. The liquid flows outwards and its pressure increases through the passage 7 to the spiral casing 8, and the outlet 9. The passage 7 may have guide vanes or widening passages as arranged in a diffuser. Where the separator is installed in the path of a circulating liquid, the pressure at its discharge end gives relief to the circulating pump.

Abstract: 949,010. Heating granular material; preheating cement raw materials. F. L. SMIDTH & CO. A.S. June 14, 1962, No. 22941/62. Headings F4B and F4U. In a heat exchanger of the kind for transferring heat from hot gas to a pulverized material, which comprises a riser pipe 4 for the upward flow of gas and which contains an inlet through which particles of material may enter the pipe, the upper end of said pipe communicates through a separator with a dust collector which in turn communicates with a collecting chamber 17, a direct connection 16 being provided between the separating chamber and the collecting chamber to allow coarser particles separated from the gas to by-pass the dust collector and fall direct into the collecting chamber 17. As shown, hot flue gas, e.g. from a cement kiln 1, passes through connection 3 into riser pipe 4. Pulverized material is fed by a worm feed 18 into pipe 4 and the hot gas with the pulverized material entrained in it passes through pipe 6 which leads into two curved branch pipes 7 (not shown) and 9. These together with the wedge-shaped space 12 in the casing 10 form the separator. Coarse particles are thrown outwards against the walls of branch pipes 7 and 9 and pass downwards through space 12 and through gap 16 into the collecting chamber 17. The gases with the finer particles pass horizontally between the plates 11 of an electrostatic precipitator arranged in the casing 10, being sucked through by fan 20 which discharges into a chimney 22. The fine particles are deposited on the plates 11 which are vibrated periodically, and the particles dropping down into collector chamber 17 from which they are withdrawn by a worm conveyer 23. If one of the electrostatic precipitators needs servicing it can be closed down and the heat exchangers can work on the other electrostatic precipitator alone. To prevent overheating, an inlet 24 in the pipe 6 may be opened to dilute the hot gases with atmospheric air.
