Title: Air conditioning system
IPC: F24F11/75
Filed: 1960-12-29
Abstract: 923,277. Ventilators. WARREN WEBSTER & CO. Inc. Dec. 29, 1960 [March 10, 1960], No. 44559/60. Class 137. Air-flow control apparatus comprises a damper 11 so pivoted at 12 that flow of air over the damper from the leading edge 11a to the pivot 12 produces a " lift " component of force that tends to swing the damper in an anti-clockwise direction as shown in Figs. 1 and 2. This force is substantially counterbalanced by a mechanical torque which varies according to the angle of tilt of the damper. As shown, the torque is produced by a counterweight 13 carried by an arm 13a rigid with the pivot 12. Spring arrangements may be used instead. The damper may be constructed to prevent it completely closing either by giving it a twist or providing a spacer on one edge. The limit stop member 14 can be rotated about the pivot 12 so that the damper can be adjusted within certain limits. The air flow apparatus is designed to produce a constant volume affresh into a unit air-conditioner, Fig. 5, which includes a heat transfer unit 30 embodying cooling and dehumidifying means and a filter 26.

Title: Refrigeration apparatus
IPC: F25D21/02
Filed: 1973-09-25
Abstract: 1399063 Supply circuits for defrosting apparatus CUTLER-HAMMER EUROPA Ltd 25 Sept 1973 [29 Sept 1972] 44891/73 Heading H2H [Also in Division F4] A control circuit for a frost sensor device 10 in a refrigerator comprises A.C. supply lines L1 and L2, bi-directional thyristors Q1 and Q2, a programmable unijunction transistor Q3, a semi-conductor device such as a N-P-N transistor Q4, a thermistor PTC, a relay RC, a power transformer T, half wave rectifier diodes D1, D2, D5 and Zener diodes D3, D4. D6. Connected into the circuit are the compressor motor CM, a defrost heater H, an electric thermostat TH, and the frost sensor device 10 which comprises a photo-conductive cell 24 and a lamp 22. In operation of the compressor motor CM, frost builds up on the refrigerator cooling element 12. This results in increased illuminance in the housing 20 and consequently cell 24 decreases in resistance thereby decreasing the magnitude of voltage Vg to which gate G3 of Q3 is subjected. When voltage Vg decreases in value to Va, Q3 is turned on. Conduction of Q3 brings the potential of its anode A3 close to ground, and the potential drop across D4 exceeds its breakdown voltage to cause current to flow through relay coil RC3. Opening of contacts RC1 and closure of contacts RC2 then results. Consequently, Q1 is rendered non-conducting to de-energize motor CM, if previously energized, and Q2 is rendered conducting to energize defrost heater H. As the defrost cycle proceeds, when the temperature of thermistor PTc reaches its curie point, a sharp rise in voltage at the cathode of D6 occurs. When its voltage exceeds the breakdown voltage across D6, current will then flow from conductor 33 through resistance R8, and diode D6 into Q4. When transistor Q4 is conducting, current flowing through resistor R7 is shunted through the collector-emitter circuit of Q4 to ground, thereby shutting off current flow through relay coil RC3 and Q3- and resistors R4 and R5. Consequently, coil RC3 is de-energized and contacts RC1 reclose and contacts RC2 reopen. Accordingly, defrost heater H is de-energized and the gate circuit of Triac Q1 is again readied to effect conduction of the latter whenever the thermostat TH functions to complete the gate circuit.

Title: Temperature rate control for a gas turbine
IPC: F02C9/28
Filed: 1970-09-25
Abstract: 1328356 Automatic control of temperature GENERAL ELECTRIC CO 25 Sept 1970 [27 Oct 1969] 45893/70 Heading G3R Also in Division F1] To avoid thermal shocks in a gas turbine when starting from cold the fuel input to the turbine is controlled to control the rate of increase in temperature of the turbine. The exhaust gas temperature is sensed and the control system is effective to cause the sensed temperature to follow a time varying reference signal significant of the allowable temperature increase rate (e.g. 5 degrees/sec) during the start-up period and until the turbine is up to its final running temperature (i.e. maximum allowable exhaust gas temperature) and predetermined operating speed. During this warm up period the temperature control over-rides all other controls of the turbine, to limit the fuel input thereto. For this latter purpose the control system includes a minimum value gate Fig. 1 (not shown) which responds to the lowest input control signal (start-up, temperature, speed) and controls the fuel accordingly. When the turbine is up to speed, the speed control assumes responsibility for the running of the turbine. The exhaust temperature is sensed by a sensor 52 (Fig. 2) which feeds a positive temperature dependent signal to a summing junction 54 (or comparator). The comparator also receives a negative polarity reference signal significant of the maximum allowable temperature and set up by a variable resistor 47. The output of junction 54 is the algebraic sum of these signals and is fed via amplifier 45 and the said gate to control the fuel supply. A third input to the junction 54 is the time varying reference signal in the form of a linear ramp of positive polarity and from a rate control circuit 25. This input signal opposes and is substracted from the maximum allowable temperature reference signal. Thus at startup, a switch 43 is closed and a positive voltage from a pot 33 is applied via R39 to the summing junction 54 the output of which tends to assume positive polarity resulting in less fuel to the turbine. When the turbine fires, the switch 43 is opened and C41 begins to charge negatively and linearly via a constant current circuit including a transistor 45 and at a rate which may be increased by closing a switch 59. As C41 charges negatively, the potential at the cathode of diode 35 reduces toward zero linearly so that the output of 54 becomes gradually more negative resulting in increased fuel supply and an increase in the instantaneous allowable turbine temperature.
