摘要： The performance of a compression ignition internal combustion engine is improved by optimizing a cylinder pressure-dependent parameter on a full time, full range basis using in-cylinder pressure measurements to determine the actual value of the parameter to be optimized. The basic procedure is to determine the desired or optimum value of the parameter, determine the actual value of the parameter or a related parameter, and then adjusting an engine operating characteristic such as air/fuel ratio to maintain the controlled parameter at its optimum value. The preferred parameter is a cylinder pressure ratio (CPR) obtained by dividing first and second values of cylinder pressure, and sensed at different points in a thermodynamic cycle, by one another. The sensed values are preferably a first value P0, obtained during the compression stroke, and a second value Pa, obtained after combustion is complete. Direct in-cylinder pressure measurements can also be used for other purposes such as knock detection, determination of maximum cylinder pressure (MCP), and engine controls dependent thereon.
摘要翻译：通过使用缸内压力测量在全时间，全范围的基础上优化气缸压力参数来确定要优化的参数的实际值来提高压缩点火内燃机的性能。基本过程是确定参数的期望值或最佳值，确定参数或相关参数的实际值，然后调整发动机运转特性，如空燃比，将受控参数保持在最佳值。优选的参数是通过将气缸压力的第一和第二值除以热力循环中的不同点彼此分离而获得的气缸压力比（CPR）。感测值优选地是在压缩冲程期间获得的第一值P0，以及在燃烧完成之后获得的第二值Pa。直接的缸内压力测量也可以用于其他目的，例如爆震检测，最大气缸压力（MCP）的确定以及取决于其的发动机控制。

摘要： A device for mirror-polishing the end of an optical fiber connector or similar elongate workpiece into a convex shape. A first grindstone polishes the workpiece while a second grindstone corrects the work surface of the first grindstone when it is deformed. The work surfaces of the first and second grindstones run in perpendicular directions or in inclined directions, so that an arcuate concavity having a circular or oval cross-section is formed in the work surface of the first grindstone. Electrolytic dressing is applied to the work surface of the first grindstone to provide it with high processing ability at all times. When the concavity of the first grindstone is deformed, the second grindstone corrects it with the work surface thereof.

摘要： A grinding machine having an angular type grinding wheel and a dressing apparatus therefor. The grinding wheel is formed with first and second grinding surfaces usable for grinding a cylindrical surface and shoulder end surface of a workpiece, respectively, and first and second reference surfaces parallel to the first and second grinding surfaces, respectively. The positions of the first and second reference surfaces and the first and second grinding surfaces are detected with touch bars before each dressing operation so as to obtain a first distance between the first grinding surface and first reference surface, and a second distance between the second grinding surface and second reference surface. After that, a first dressing amount for dressing the first grinding surface and a second dressing amount for dressing the second grinding surface are so determined that the first distance and the second distance would have a predetermined constant relationship after dressing operation. The first grinding surface is then dressed by the first dressing amount, while the second grinding surface is dressed by the second dressing amount.

摘要： An apparatus is described that converts a manual adjustment procedure of a lathe on an existing pulp-grinding machine into an automated electronic procedure. The pre-existing lathe has a sharpening burr affixed to a movable plunger. The plunger is manually lowered by a hand crank until the burr contacts a surface of a pulp-grinding stone. The present invention replaces the hand crank with a reversible, variable speed motor. A transducer is affixed to the plunger wherein electric signals are produced in response to vibrations resulting from contact between the burr and the grinding stone. The signals are processed by a standard programmable controller to control the motor. An electronic encoder electrically measures the position of the plunger and communicates the position to the programmable controller. When the burr on the plunger contacts the grinding stone, the motor is programmed to automatically stop. The controller can then direct the motor to move the plunger the precise depth required for a specific burr, prior to the lathe making a horizontal pass along the stone. The controller records the contact position of the plunger for the next sharpening procedure.
摘要翻译：描述了将现有纸浆研磨机上的车床的手动调节过程转换为自动化电子程序的装置。预先存在的车床具有固定在活动柱塞上的磨刀毛刺。柱塞通过手动曲柄手动下降直到毛刺接触到纸浆磨石的表面。本发明用可逆式变速电动机代替手动曲柄。换能器固定在柱塞上，其中响应由毛刺和磨石之间的接触产生的振动而产生电信号。信号由标准可编程控制器处理以控制电机。电子编码器电测量柱塞的位置并将位置传递到可编程控制器。当柱塞上的毛刺接触磨石时，电机被编程为自动停止。然后，控制器可以在车床沿着石头进行水平通过之前，引导电机将柱塞移动到特定毛刺所需的精确深度。控制器记录柱塞用于下一个锐化程序的接触位置。

摘要： A center lapping apparatus for precisely lapping center holes in opposite ends of the workpiece prior to outside diameter grinding of the workpiece includes a conical lapping stone and a dressing apparatus that supports a dressing stone for periodically dressing the lapping stone. Movement of the dressing stone during any dressing operation is confined to a plane in which an axis of symmetry of the lapping stone lies. A spring loaded pin disposed in a movable head of the dressing apparatus has a slightly tapered end which precisely fits in a stationary hole of a mounting bracket about which the movable head pivots. The tapered end of the spring loaded pin ensures that the dressing stone can always be returned to precisely the same position for a dressing operation despite wear of the spring loaded pin. A precise flat surface of the moveable head slides against a precision flat surface of the stationary plate during pivoting of the movable head. The flat surfaces are parallel to the plane in which movement of the dressing stone is confined.

摘要： A steel strip grinding machine for the continuous grinding of the upper and lower surfaces of steel strips includes a pair of vertically displaceable spindles into which the grinding rolls are journalled. One of the spindles is slidable axially whereas the other spindle is fixedly secured in the machine frame. The grinding rolls are thus removable through sliding of the axially slidable spindle without having to disassemble any bearings. The lower grinding roll is supportable on a lift truck mechanism for movement in and out of the machine frame whereby removal of such grinding roll for the lower surface of the steel strip can be effectuated without use of a crane. Further, a device for dressing the outer peripheral surface of the grinding roll is provided adjacently to the grinding roll. The grinding roll is made by spraying a thermosetting resin containing hone grains upon a nonwoven fabric in which filaments are entangled at random. Its shaft is formed to be hollow. The above mentioned spindle is so formed as to be engaged at the tip with each end of the shaft.

摘要： A wheel guard or pedestal support is disposed for mounting on a grinding machine and provides a dovetail guide into which there may be removably mounted a diamond dresser; a contour forming device; an edge deburring support and like grinding wheel dressing apparatus. Precision lead screws are mounted in member portions of the support, said screws being disposed to be rotated to move a mounted dressing device into a desired precise position. A plunger pin is carried by a member and cooperates with an aperture in a mating member to permit a dressing device to be removed during grinding operations and to be reinstalled at the precise prior dressing position. In one embodiment a contour dressing mechanism is provided in which a diamond-surfaced precisely contoured wheel is rotated in the same direction as the grinding wheel is rotated but at a speed differential of about 400 surface feet per minute. This operation of the contour dressing mechanism provides a dressing of the grinding wheel whereby the wheels and dresser are kept at a relatively cool condition and the diamond wear is at a very low rate.
