摘要： In a cooking oven which is cleaned by pyrolyzation of soil within the oven cavity and has a smoke eliminator duct extending through the oven wall, with a smoke eliminator heater disposed adjacent to the duct inlet, a reducing gas sensor is mounted either adjacent to the oven end of the smoke eliminator duct or within the smoke eliminator duct near its discharge end. An electrical relay or microcomputer control is coupled between the gas sensor and the heater to initially heat the oven interior and to later deenergize the heater when the reducing gas sensor output indicates a desired oven condition. The oven heaters are temporarily deenergized when the gas sensor output indicate a smoke eliminator overload. If the gas sensor is mounted in the smoke eliminator duct, the smoke eliminator heater may be deenergized toward the end of the cleaning cycle, so that the effluent is not affected by the smoke eliminator heater before reaching the gas sensor. Plural smoke eliminator heaters are also disclosed to enable increase of heater power during the early cleaning stages and reduction of the heater power during the later cleaning stages.

摘要： A cavity, such as an oven cavity, is heated by at least one monolithic integrated heat source, each fabricated by depositing a layer of resistive material on a substrate of non-conducting, or insulating, material. A pair of spaced-apart conductive elements contact opposite ends of the resistance sheet to enable a flow of current through the sheet thereby producing substantially uniform heating over the entire area covered by the resistive sheet.

摘要： A system and method for monitoring machine tool operations provides a multi-level tool break alarm and uses information from multiple sensors of different types. Signal processing and pattern recognition logic techniques are applied to a cutting process high frequency vibration signal to detect major tool breaks requiring prompt stoppage of the cut. False alarm resistant detection of minor tool breaks, for which the response may not be an immediate stop of the cutting process, is obtained with information from a low frequency vibration sensor, an axis drive current sensor, or an axis velocity sensor. A minor tool break alarm is generated when signal transients in both a high frequency and low frequency channel signal are in close time coincidence, and a major alarm when the high frequency channel transient is followed by a persisting mean vibration level shift.

摘要： Sharp tools have different cutting characteristics from dull or worn tools. Among these differences is that a wear land develops on the cutting tool so that more of the cutting tool comes into contact with the workpiece during the cutting process. The increased contact area between the tool and workpiece forces more energy to be consumed by the cutting machine in making a cut because more energy is expended in non-productive work. Indications of an increase in non-productive work are the increased power or force necessary to operate a spindle in lathes, milling machines, etc., and the increased energy in cutting vibrations in a low frequency range emitted during the cutting process. Another indication of decreased efficiency of the cutting process is the decreased energy in cutting vibrations in a high frequency range emitted during the cutting process. A method and apparatus are described for continuously monitoring a ratio of spindle force or power or low frequency vibration energy to high frequency vibration energy during the cutting process, and generating an output warning signal when the radio reaches a preselected level correlated with excessive tool wear.
摘要翻译：锋利的工具具有不同的切割特性，从钝或磨损的工具。这些差异在于，在切割工具上形成磨损区域，使得更多的切削工具在切割过程中与工件接触。刀具和工件之间的增加的接触面积在切割机中产生更多的能量消耗，因为在非生产性工作中消耗更多的能量。增加非生产性工作的迹象是在车床，铣床等中操作主轴所需的力量或力量的增加，以及在切割过程中发射的低频范围内切割振动的能量增加。切割过程效率降低的另一个指示是在切割过程中发射的高频范围内的切割振动中的能量减少。描述了一种用于在切割过程中连续监测主轴力或功率或低频振动能量与高频振动能量的比率的方法和装置，并且当无线电达到与过度的工具磨损相关的预选级别时，产生输出警告信号。

摘要： A Machine Tool Monitor detects significant cutting tool breakage and the first contact of an advancing tool to a workpiece, and does this by monitoring vibration signals produced by the machining of parts and interpreting patterns in these signals. Information from the part program improves the performance of the detector and optimizes it for the cutting conditions called for by the machine tool control. The analog channel gain of the monitor is adjusted and parameters controlling the digital pattern recognition logic are selected using part program information on machining parameters. The tool touch or tool break detection mode is selected by the part program.

摘要： Substantial cutting condition changes that occur gradually, as opposed to the more usual sudden large change, are detected by setting upper and lower cutting noise mean level thresholds. When the mean cutting noise exceeds the upper threshold or stays below the lower threshold for a preset number of signal samples, a tool break alarm is generated. Techniques are given to reduce false alarms at the start and end of the cut and on runout on initial rough surface cuts. The system comprises an accelerometer or other sensor whose signal is preprocessed to attenuate lower frequency machinery noise and detect the signal energy in a band below 100 KHz, then sampled, and the digitized signal samples analyzed by pattern recognition logic.

摘要： A highly maneuverable water craft for recreational enthusiasts with two hydraulically controlled and driven reversible propellers directionally fixed to a toroidal peripheral hull section which encircles a thinner interior platform section. The toroidal exterior hull provides stability for the platform in water, allowing the water craft to quickly spin, translate, stop and start. The directionally fixed propellers are not impacted by translation or spin and provide rugged and simplified construction. Placement of two fixed reversible propellers on the peripheral hull section provides maximum turning torque and allows elimination of a rudder or directional actuators. Control is provided by a novel pilot actuator and four-way valves assembly. Bumper strips, propeller guards, handholds and deadman switches can be provided for safety in handling this extremely maneuverable water craft.

摘要： This tool break detection system relies on monitoring changes in the cutting noise itself, rather than detecting the tool fracture acoustic signal. A broken tool capable of damaging the workpiece is detected, and tool break events that do not affect cutting conditions are ignored. The signal from a sensor such as an accelerometer is preprocessed to attenuate low frequency machinery noise and detect the signal energy in a band below 100 KHz, then sampled, and the digitized signal samples analyzed by pattern recognition logic. Runout false alarms during rough surface cutting are prevented; after detection of an abrupt increase or decrease in signal level, the confirmation period to test for a persistent shift in mean level is set longer than the workpiece revolution period.
