摘要： A semiconductive encoder comprises a rotor having field-effect transistors the insulated gates of which are mounted on a stator. The stator comprises a backwardly biased p-n pattern which creates dielectric fields for the rotor transistors. Relative movement between rotor and stator varies the current through the insulated-gate field-effect transistors to provide a digital indication of the relative position of rotor and stator.

摘要： A nozzle having a set of flaps is formed on the exhaust end of a turbojet engine. Seal means are provided between adjacent flaps so that the area between the nozzle flaps will have a minimum flow loss between them as they are moved between their minimum area position and maximum area position. A seal flap is located between each pair of nozzle flaps and is maintained centered by a track on the seal flap and links connected to the adjacent sides of the nozzle flaps. A guide at the free end of the links is guided on said track. A guide member positions the flap axially and prevents it from being lifted from the surface of said nozzle flaps.

摘要： A load is connected across one DC source of a first polarity and is connected to the opposite polarity of a second DC source, the two sources being connected in series with a capacitor/resistor network, or other voltage maintaining circuit, connected in parallel with the series combination of the two sources. The first source drives the load in one polarity and the second source drives the load in the other polarity thereby to achieve rapid slewing of the voltage across the load. In another embodiment a fixed power source may be connected in series with the first power source so that the slewing of voltage across the load occurs above a given reference level. The first and second sources are driven in a complementary fashion so that the sum of their instantaneous output voltages is always constant and equal to the individual maximum voltage which each may obtain. Since the slewed sources comprise a high voltage bilateral system, feedback may be utilized for stability and accuracy.
摘要翻译：负载连接在第一极性的一个DC源上，并且连接到第二DC源的相反极性，两个源与电容器/电阻器网络或其他保持电路串联连接，并联连接到系列组合的两个来源。第一个驱动器以一个极性驱动负载，第二个驱动器以另一个极性驱动负载，从而实现跨负载的电压的快速回转。在另一个实施例中，固定电源可以与第一电源串联连接，使得横跨负载的电压的回转高于给定的参考电平。第一和第二源以互补的方式驱动，使得其瞬时输出电压的总和总是恒定并且等于每个可获得的单个最大电压。由于压电源包括高压双边系统，因此可以利用反馈来获得稳定性和准确性。

摘要： A fuel control for gas turbine power plant adapted for automotive use includes an open loop scheduling control for acceleration which varies the pressure drop across the metering orifice as a function Wf/P3 (Wf fuel flow in pounds/hours, P3 compressor discharge pressure in pounds/square inch absolute) and varies the area of said metering orifice as a function of P3 divided by another engine operating parameter such as turbine exhaust temperature to effectuate multiplication of the Wf/P3 and P3 values for establishing the value of Wf, where Wf/P3 is scheduled by the foot pedal position.

摘要： A magnetic pickup located in close proximity to a gear mounted on a vehicle wheel or axle produces a series of pulses indicative of wheel velocity. A binary up/down counter is set to a preselected binary count, and the wheel velocity pulses are alternatively directed to the up and down inputs of the counter for equivalent intervals of time. Any count remaining in the counter after the up and down counts which differs from the preselected count indicates acceleration or deceleration of the wheel, and the appearance of a binary one in any one of several preselected bits in the counter at the end of a counting cycle cause the application or release of the wheel brakes.

摘要： An elastomeric helicopter rotor having a blade mounted for universal motion about the intersection of the blade pitch change, flapping and lead-lag axes and including blade coning and droop stops, including a ring member rotatably mounted about the pitch change axis on the blade and coning and droop stops constituting segments of circular members whose centers lie on the blade lead-lag axes and with the ring member and coning stop and droop stop members presenting mating surfaces to one another so that as the blade moves in lead-lag motion while the blade ring member is in line or surface mating contact with either the coning stop surface or the static or dynamic droop stop surfaces, a relative rotation will be established therebetween for full support of the blade throughout the lead-lag motion, without affecting blade pitch angle or flapping angle, without preventing independent blade pitch change, and without scuffing of parts.
