An energy generation system for generating energy to be supplied to a chip zapping unit of for example a gas turbine engine comprises an ignition system, e.g. that of the gas turbine engine, the ignition system having an energy output and configured to supply operational energy to the energy output, and the chip zapping unit having an energy input, the energy input coupled to the energy output of the ignition system to receive the operational energy therefrom. Such an energy generation system generates the operational energy needed for the chip zapping unit directly from the ignition system thus avoiding pulse generation circuitry inside an electronic control unit.

The present disclosure is directed to an improved metalworking lubricant monitoring, logging, recording, calculating, analyzing, alerting and reporting apparatus, system and method that monitors data and changes to the lubricant application process and the amount and concentration of lubricant being dispensed or delivered, analyzes, calculates and records data and changes or alterations to the amount dispensed, and alerts or reports the data and changes in real-time, when necessary, over various communication channels, to those responsible for overseeing the system changes.

A lubricant cartridge container includes a cylindrical member, and a moving member moving inside the cylindrical member toward a lubricant inflow portion side as a fluid lubricant flows toward the lubricant inflow portion side when subjected to a suction force from a lubricating pump side. The moving member has a first moving main body portion moving inside the cylindrical member and contacting with a shoulder portion, and a second moving main body portion contacting with the lubricant inflow portion after the first moving main body portion comes in contact with the shoulder portion. The second moving main body portion has a center portion contacting with the lubricant inflow portion, and a step portion connecting the center portion and the first moving main body portion. The center portion has a recess recessed in a polygonal shape formed by connecting a plurality of apexes in a plan view.

A system for managing a flow-state of fluid includes: a flow detector; a management unit; and a temperature sensor. The management unit includes: a valve body opening/closing detection portion; an actual opening/closing time calculation portion that calculates, as an actual opening/closing time, the time from when the opening/closing detection portion detects the opening of the valve body until the same detects the closing thereof within a defined detection time; a correlation storage portion that stores a correlation between the temperature of the fluid and an appropriate opening/closing time range that is appropriate for the valve body; an opening/closing time determination portion that determines whether the actual opening/closing time is within or outside the appropriate opening/closing time range derived by an appropriate time range derivation portion; and an abnormal signal transmission portion that transmits an abnormal signal when the actual opening/closing time is determined to be outside the range.

There is described herein methods and systems for detecting of metallic chips in a fluid system of an aircraft engine. A resistance value is measured across a magnetic chip detector mounted to a fluid system of the aircraft engine. The resistance value is transmitted to an engine computer of the aircraft engine. In the engine computer, The resistance value is compared to a first threshold and a first warning indicative of a chip in the fluid is issued when the resistance value exceeds the first threshold.

The invention relates to a lubricating device that includes a lubricant pump, a lubricant reservoir for supplying lubricant to a machine to be lubricated, a control unit for determining an operating state of a machine and for operating the lubricant pump based on the signals of at least one sensor configured to detect emissions emanating from the machine to be lubricated, and a housing configured to be attached to a lubrication nozzle of the machine to be monitored. It is proposed that a reading of the signals of the sensor by the control unit is limited to a predetermined set of time windows with a predetermined width, wherein the time windows are separated by an interval where the signals of the sensor are not read.
