Filed: 1974-03-18
Abstract: 1405082 Automatic control AMF Inc 18 March 1974 [10 April 1973] 11848/74 Heading G3N [Also in Divisions H 1 and H3] Means for controlling the defrosting cycles of one or more refrigerating units comprises means whereby the defrosting cycles are controlled according to an ambient parameter such as humidity. A refrigerating unit RU 1 comprises a compressed motor CM1 and a defrosting heater DH 1, controllable by switches SC 1, SD 1 which are operable by a timing motor TM1 so as to be energized alternatively. Energization of the timing motor TM 1 is normally controlled by a switch SA1 which closes upon the initial movement of a cam device MCC 1 which is driven by a variable speed motor VSM, the speed of rotation of which is determined by the humidity of the atmosphere surrounding the refrigerating unit RU1, the humidity being sensed by a resistive transducer HS. Initial rotation of the motor VSM moves the cam device MCC1 to close the defrost initiate switch SA1 momentarily thereby energizing the timing motor TM 1. Rotation of this motor moves a cam FIA to close a self maintaining contact SB 1 for the motor, opens switch SC 1 to stop the compressed motor CM1 and closes switch SD1 to energize the defrosting heater DH1. When sufficient defrost has been achieved a switch TP1 closes to energize a solenoid TS 1 which operates the switches SC1, SD1 to the normal positions so ending the defrosting operation and resuming the cooling operation. The timing motor TM 1 will however continue to run until the cam FIA reopens the self maintaining switch SB 1. If a timed defrost period is required a further switch SBP1 is closed to energize the motor TM1. The system may comprise a plurality of refrigerating units RU1-RU4 controllable, if situated in the same ambient atmosphere, by a single humidity sensor and variable speed motor driving a series of cams, the cams being displaced relatively to one another, so that the respective defrost periods are initiated singly and in succession so as not to overload the electrical supply system.

Title: Gas turbine fuel control
IPC: F02C9/32
Filed: 1975-03-27
Abstract: 1498664 Automatic control of gas turbine engines GARRETT CORP 27 March 1975 [1 April 1974] 12949/75 Heading G3N [Also in Division F1] In a fuel control system for a gas turbine, a compressor bleed valve is opened if a surge schedule is limiting, and closed if the turbine fuel flow is a predetermined amount below the surge schedule. In a control system for a double spool aircraft turbofan gas turbine engine, the engine inlet temperature Tt 2  and pressure Pt 2 , compressor discharge pressure P 3 , inter turbine temperature Tt 5 , and speeds N H , N L  of high and lowpressure spools respectively, are measured. Schedules are derived for engine starting, acceleration, surging, minimum fuel and deceleration. A lowest wins logic 113 selects the lowest value from the start, acceleration and surge schedules, the inlet temperature Tt 5  and information dependent upon the position of a power lever, as set by the pilot. A highest wins logic 118 is fed with the output of logic 113, minimum fuel and deceleration schedules, the highest of which is used to control the engine fuel flow. A surge valve, which bleeds air from the engine low-pressure compressor, is controlled in accordance with the output of the surge schedule, power lever position and the desired fuel flow i.e. the output of highest wins logic 118. During engine acceleration, the fuel flow is limited by either the acceleration schedule, according to N L  and Tt 2 , or by the surge schedule, according to N L , N H  and the surge valve position. When the fuel flow is limited by the surge schedule, the surge valve is opened and the fuel'flow increased after a suitable delay. If the fuel flow is less than the surge schedule by the predetermined amount, the surge valve is closed and the fuel schedule reduced. The compressor bleed is thus continuously adjusted as the engine speed changes, and the fuel flow-surge valve position relationship prevents compressor surge and excessive bleed with its associated loss of engine efficiency.
