Abstract: An angular rate sensor comprising a pair of accelerometers that includes means for continuously nulling error signals resulting from misalignment of the accelerometers. The first accelerometer (10) has a first force sensing axis and produces a first output signal (a1) indicating acceleration along the first force sensing axis. The second accelerometer (12) has a second force sensing axis and produces a second output signal (a2) indicating acceleration along the second force sensing axis. The accelerometers are mounted by mounting means such that their force sensing axes are both parallel to a common sensing axis and such that the accelerometers can be moved along a vibration axis normal to the sensing axis. A signal generator (76) produces a periodic drive signal having a predetermined frequency, and drive means (80, 82, 84) connected to the mounting means is responsive to the drive signal for vibrating the first and second accelerometers along the vibration axis at the predetermined frequency. Signal processing means (104) receives the first and second output signals and generates a Coriolis signal representing the Coriolis acceleration along the sensing axis resulting from movement of the accelerometers along the vibration axis and rotation of the body about a rate axis normal to the vibration axis and to the sensing axis. The signal processing means includes the detection means (92) that receives the Coriolis signal and produces a feedback signal that is a function of those components of the Coriolis signal that are in phase with respect to the drive signal. The drive means includes means (80) for combining the feedback signal with the drive signal, such that the in phase components are continuously driven towards a null value.

Abstract: ''Doorbelling'' in a generating system including a fault detecting circuit is prevented without the use of auxiliary power supply for a generator control unit. The generating system includes a permanent magnet generator (14) driving an exciter winding (18) and a relay (26) is utilized for interconnecting the two. Control of the relay (26) is exercised by a microcomputer (32) including a non-volatile memory (48) and programmed (Fig. 3) to remember the occurrence of a fault and thereafter prevent the relay (26) from cyclically opening and closing in response to power changes occurring as a result of connection and disconnection of the exciter winding (18) from the permanent magnet generator (14).

Abstract: The differential transmission mechanism has an output differential (10). A first hydraulic displacement unit (18) having a normally fixed, approximately maximum displacement is connected to the output differential. A second hydraulic displacement unit (16) which is of variable displacement is connected to an input shaft (12). Additional components of the output differential are connected to the input shaft (12) and to an output shaft (14). An output shaft speed sensing device (32) controls the displacement of the variable displacement hydraulic displacement unit (16) to achieve a constant output speed. A sensor and control (74) responds to a reduced speed of the input shaft (12) to reduce the displacement of the fixed displacement unit (18) to effectively make the latter displacement unit a smaller, faster unit and extend the constant output speed range at the low end of the input speed range.

Abstract: Resistance to centrifugally acting forces in an axially and radially compact rectifier assembly particularly suited for mounting in a rotary component of a dynamoelectric machine is achieved in a full wave, three phase rectifier assembly. The assembly includes first and second blocks (18, 20), each having three radially outwardly facing diode receiving surfaces (22, 24, 26). Six diode wafers (28) are located on the surfaces and are sandwiched thereagainst by six electrically conductive load shoes (40). Three phase conductors (54) are interposed between the load shoes (40) and a shrink fitted cylindrical housing (10) and electrically connect aligned load shoes (40) associated with each of the blocks (18 and 20).

Abstract: A permanent magnet generating system includes first (14) and second (16) permanent magnet generators, or PMG's each having a permanent magnet rotor structure (22, 24) and a stator structure (26, 28). Each stator structure has at least one stator winding (30, 32) disposed therein and the stator windings of the PMG's are connected in series so that the voltages developed thereby add vectorially to develop a combined output voltage. The position of the stator windings of one PMG is adjustable relative to the position of the stator windings of the other PMG to vary the phase angle between the two output voltages of the PMG's so that the combined output voltage can be controlled at a desired value irrespective of changes in operating speed or load.

Abstract: An energy source for a closed cycle engine including a boiler (10) having a working fluid chamber (12) in heat exchange relation with a reaction chamber (14). A closed flow path loop (16, 34, 36, 38, 44, 46, 52) including a turbine (18) receives working fluid from the fluid chamber, provides a power output and returns the fluid to the chamber. Lithium (80) is reacted with water (70) in the reaction chamber (14) to generate heat for heating the working fluid and hydrogen. Oxygen, obtained by decomposition of sodium superoxide (82) elsewhere in the system, is fed to the reaction chamber (14) and combined with the hydrogen to provide water and additional heat for the working fluid.

Abstract: A thrust reverser actuation structure utilizing a single power source (60) for controlling the operation of thrust reverser actuators (26, 40) associated with plural jet engines (12, 16). The thrust reverser actuation structure has a power drive unit (60, 74) with an output shaft (62) that can be located in the fuselage of an aircraft and a pair of mechanical drive trains (68, 70) extend therefrom and are connected separately to the thrust reverser actuators (26, 40) of jet engines (12, 16) located on opposite wings of an aircraft. With the single power source (60) and the mechanical drive train the occurrence of a jam in the thrust reversers of one jet engine will result in stopping the power drive unit and the thrust reversers of the other engine at the same position as those that are jammed. This minimizes the likelihood of asymmetric reverse thrust.

Abstract: A positive displacement scroll type apparatus having first and second scrolls (10, 12) with interfitting vanes (18) defining an interface which includes at least one close pocket (20) adapted to move fluid from an inlet (22) to an outlet (24). The outlet (24) is located in one of the scrolls and is subjected to centrifugal force during operation of the compressor and this in turn causes the separation of lubricant from the compressed fluid by such centrifugal force. A lubricant collector (46, 48, 50, 54) is located at the oulet (24) to prevent the lubricant from entering the remainder of a system with this the compressor may be associated.

Abstract: A rotary rectifier assembly including a shaft (38) adapted to be rotated. Three equally angularly spaced phase conductors (68) are disposed about the shaft (38) and insulated (by 66) with respect to each other and with respect to the shaft (38) and each has opposed, axially opening recesses (72). Diode wafers (74) are received in each of the recesses (72) and each recess (72) further receives an electrically conductive load shoe (76). A pair of end conductors (84, 86) sandwich the phase conductors (38), wafers (74) and load shoes (76) and each end conductor (84, 86) has three equally angularly spaced curved recesses (88) for matingly receiving the curved portion (80) of the corresponding ones of the load shoes (76). A single biasing device (108) is employed to bias one end conductor (84) towards the other (86) to thereby establish good electrical contact between the various components while occupying a minimum of space and minimizing the overall weight of the assembly.
