Abstract: 738,624. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. Sept. 22, 1953 [Oct. 14, 1952], No. 26095/53. Class 114. A control for a propeller having adjustable pitch blades 12 and means for moving the blades to increase and decrease their pitch comprises a rheostat 56 connected with the blades for producing a signal proportional to the pitch, a rheostat 50 connected to a control mechanism 48 for producing a signal proportional to the position of the control mechanism, signal comparing means 54 connected to both rheostats 50, 56 for providing a resultant signal dependent on the preponderence of one signal over the other which is used to cause increase or decrease of the pitch. The resultant signal is used to operate a switch 80 which either connects a battery 64 to line 82 and to a switch 60 which is closed by the mechanism 48 when set to a pitch angle below 7 degrees. whereby current is supplied to a pitch decreasing valve 28, or to line 94 whereby current is supplied to a pitch increasing valve 38, the valves 28, 38 disabling the governor 16. The switch 80 is connected to the battery either through a switch 84 actuated by the propeller in accordance with its pitch and a switch 86 closed by contact of the aircraft with land or water/or through a switch 96 closed by a "start-run" lever 118. A feather control button 106 is pushed to energize a hold and timer device 108, 110, to close switch 114 which starts the feathering pump 44 and to supply current to the pitch increase valve 38. Pulling button 106 supplies current to operate the feathering pump 44 and to the pitch decrease valve 28, through a switch 116 controlled by the "startrun" lever 118. The mechanism 48 is also connected to and controls the engine throttle control 102 which during movement of the mechanism 48 in one direction closes the throttle then opens it again as the blades are reversed. In order to prevent stalling of a turbine when the blades are moved to reverse pitch the circuit may be modified by applying to the rheostat circuit 50 of the means 54 a reference voltage which is modified by the turbine speed and which feeds a signal to the means 54 when the signal voltage from the rheostat 50 is less to decrease the reverse pitch.

Title: Electronic balance

Filed: 1973-05-31
Abstract: 1401393 Measuring weight photo-electrically LECO CORP 31 May 1973 [16 Feb 1973] 26120/73 Heading G1A [ Also in Division H3] Automatic, electronic weighing apparatus comprises means for providing a plurality of electrical pulses representing the weight of an object, means for storing a signal representing this plurality of pulses and means for comparing a signal representing a second plurality of pulses representing a second measured weight with the first signal and means for applying only those pulses of the second plurality in excess of the first to output and display means, and means to blank one display if the stored weight is greater than the object weight. In operation, the tare weight of a sample holder is first measured and stored and this stored weight is subtracted from all subsequent measurements. As shown, a crucible 24 is first weighed by placing it on balance beam 35. Movement of this beam in a clockwise direction causes more light from L.E.D. 46 to reach phototransistor 48 and thereby allows more current to pass through transistor 44 in virtue of its base connection. This current is indicative of the weight 24 and a voltage at 66 indicative of this current is produced across resistor 45. The current through transistor 44 is fed to a torque motor 41 to return the beam 35 to a balanced reference position. The voltage at 66 is compared at 60 with a sawtooth waveform generated at 50 and applied at 61. The output at A is a pulse series, the mark-space ratio of which is indicative of the weight 24. This signal is applied to circuits 110 which produce a series of bursts of pulses 105, the number of pulses in a burst being indicative of the weight. In the absence of activation of further circuits by manual switch 32, these pulses T are admitted to a counter 200 and are counted for a measurement interval consisting of a particular number of pulse bursts, and the number displayed at 220 is indicative of tare weight 24. If at anytime during the measurement interval, switch 32 is pressed, a pulse N is produced by circuits 150 just prior to a pulse R signifying the end of a measurement interval, which pulse N causes the total number accumulated in a counter at 175 to be transferred and held in a memory also at 175, the counter being reset by a pulse R. When a weight 25, placed inside holder 24, is to be measured the same cycle applies but a comparator connected with the outputs of the counter and memory prevents those pulses of the measurement bursts from passing an AND gate to the counter 200 until the number on the counter exceeds that on the memory.
