摘要： The invention is a method and apparatus for identifying and pinpointing the location of unwanted pieces of material or defects in, for example, de-boned poultry pieces. The poultry pieces to be inspected are carried on a conveyor and passed under an impinging collimated X-ray beam. The Rayleigh scattering resulting is detected and measured, as is the Compton back scattering and the data is processed in a processing unit to determine the location and type of foreign matter involved. The ratio of the Rayleigh and Compton scattering is also determined and used to verify the identity of the foreign material. Transmitted X-rays, i.e., radioscopy, are used to normalize the data, and to aid in a pinpointing of the location of the unwanted material.

摘要： In an aircraft load management center each LRU is addressed by a separate line. Power control units on an LRU are addressed by a bus to which all the LRUs are connected in parallel. Control and status inputs, and status output lines are connected in parallel to the LRUs. A programmable logic unit on each LRU decodes the controller addresses, couples control and status request inputs to the controller. The load management center automatically connects a status signal to the interface output after each control function input.

摘要： A sensor (10) for sensing the magnitude of current flowing in a conductor (12) based upon the Faraday effect is disclosed. The invention utilizes a magneto-optic material having one or more layers (32) in which alignment with an optical fiber is not critical in achieving accurate current measurements. A magneto-optic material (28) in accordance with the invention includes one or more layers (32) each having a substrate having opposed surfaces coated with a material exhibiting the Faraday effect in which light from a light source is transmitted through the magneto-optic element without substantial internal reflection and is incident upon a surface area of the coating which is greater than the surface area of the beam of light. Furthermore, the invention measures the magnitude of current flowing in the conductor accurately by utilizing null detection for a first range of current values from zero to a first magnitude having either of two possible polarities and measures a second range of current values extending from the first magnitude to a second magnitude having either of the two possible polarities in which null detection is not utilized. By not utilizing null detection for the second range of current values, circuit response time is enhanced by allowing the inductance of the nulling coil to be reduced. Transient response is thus improved.

摘要： A thermally powered electrical generating system for use in a space vehicle is disclosed. The rate of storage in a thermal energy storage medium is controlled by varying the rate of generation and dissipation of electrical energy in a thermally powered electrical generating system which is powered from heat stored in the thermal energy storage medium without exceeding a maximum quantity of heat. A control system (10) varies the rate at which electrical energy is generated by the electrical generating system and the rate at which electrical energy is consumed by a variable parasitic electrical load to cause storage of an amount of thermal energy in the thermal energy storage system at the end of a period of insolation which is sufficient to satisfy the scheduled demand for electrical power to be generated during the next period of eclipse. The control system is based upon Kalman filter theory.

摘要： A control system is provided in which a plurality of independent control elements are each capable of generating a random value and determining a time delay as a function of that random value. Each of the control elements accesses the magnitude of a sensed parameter and responds to that magnitude. When correction of the sensed parameter is required, each independent control element senses the need for a correction and delays by an amount of time determined randomly and independent from all other control elements. After the randomly determined time delay has elapsed for each control element, that control element again accesses the magnitude of the sensed parameter and, if correction is still required, changes the connection status of an associated switch. In a preferred embodiment of the present invention, the control element interrogates the status of its associated switch to determine if actuation would benefit the correction of the magnitude of the sensed parameter.

摘要： A power supply system for processing current and voltage faults is disclosed. Each phase of a first power source (12) and each phase of a second power source (28) has a pair of switches (60, 64) for controlling the conduction of current from the phase of the power source to a phase load (29). In each of the phases of the first power source (12), a first switch (60) is controlled by a first control signal which has a high level when a voltage fault or current fault condition does not exist. When either a voltage fault or a current fault condition exists, the first switch (60) is turned off. The second switch (64) is turned on by a second control signal during a determination of whether a current fault exists. Furthermore, a logic network causes the first control signal to assume the second level in response to any one of an RMS over/under voltage fault, an instantaneous overcurrent fault, an I.sup.2 t fault, or an instantaneous voltage fault occurring in the phase to which the switches are connected or in any one of the other phases in the first power source. Upon the detection of a voltage fault condition, the first power source (12) is disconnected from the load and a second power source is connected to the load. All of the phases of the first power source are disconnected either immediately in response to the detection of a fault in any one of the phases or, alternatively, the phase with the fault is immediately disconnected and the remaining phases without a fault are disconnected at the zero current crossing points of the AC signal of the phases. The phases of the second source are connected at a point when the voltage of the phase is zero.

摘要： A receptacle for firearms that comprises a primary receiving cavity for a firearm that is considered to be semi-universal and has multifunctional capabilities. This primary receptacle allows the user to adjust the receiving cavity to fit a plethora of sizes, styles, and calibers within a certain model line. This is accomplished by a series of dual adjustment springs and molded stops that function together to customize tension and squeeze within the receptacle. The compact and ergonomic design allows the receptacle to be easily interchangeable among a variety of carriage or mounting apparatuses.

摘要： An inductive coupled power system has a transmission circuit with a dual primary comprising two conductor loops. First segments of the loops extend through an area served by the system adjacent each other and second segments of the loops extend through the area one on either side of the adjacent first segments. A small loop configuration minimizes the stray magnetic field. A secondary pickup assembly has a U-shaped core with two legs which embrace the first segments of the two loops and a core element adjacent the first loop segments is positioned between the ends of the legs. Each of the power circuits of a plurality of loads includes a shunt regulator.

摘要： A voltage fault detector (10) for producing a trip signal causing switching from a first AC voltage source (12) to a second AC voltage source (14) is disclosed. A plurality of comparators (18,20,22) monitor a signal which is proportional to the magnitude of the voltage of a first AC voltage source (12) to determine if sample values fall within predetermined ranges. A counter (30) counts the number of samples falling outside the predetermined range to generate the trip signal when the count reaches a predetermined limit. The counter (30) is augmented for each sample which is outside the predetermined range and decremented for each sample which is within the predetermined range. A plurality of latches (24,26,28) are respectively coupled to a different one of the comparators for applying the output level signal from one of the comparators to the counter at predetermined times under the control of clock signal pulse trains generated by a combinational logic circuit (32) which are respectively applied to a different one of the plurality of latches. The voltage fault detector (10) may be used to monitor the condition of one or more phases of a backup voltage source.
