摘要： An electronic valve characterizer for fuel-air ratio control wherein the primary valve may be arbitrarily set and the secondary valve or valves are actuated by a slave motor or motors to a predetermined ratio of fuel to air for any setting of the primary valve. The primary and secondary valves are each controlled by motor-actuated valves, each having a slide wire and a slide. The secondary slide is set to operate at a speed in excess of the primary slide. The signal from the primary slide is passed through an amplifier having adjustable rates of amplification in each of a series of adjustable sectors of the movement of the primary slide. The amplified signal is compared with an amplified secondary slide signal and the secondary motor energize to bring the amplified secondary slide signal into general equality with the amplified primary slide signal.

摘要： A detector for detecting the position of the edges of a moving strip which produces an electrical signal proportional to the transverse position of the strip. A light source shines on the edge of the strip. A smooth surfaced sheet of translucent plastic material containing a fluorescent pigment is placed below the edge and opposite the light source. The pigment in the portion of the sheet of the strip and exposed to the light source outside the edge fluoresces producing light energy in amounts proportional to the area of the sheet exposed to the light source. This light energy travels between the sheet surfaces to the edges of the sheet. Photoelectric sensitive means are operatively associated with the edges of the sheet for producing an electrical signal proportional to the amount of fluorescent generated light energy which signal can be amplified to control power means for respositioning the strip.
摘要翻译：用于检测移动条的边缘的位置的检测器，其产生与条的横向位置成比例的电信号。光源照在条的边缘。含有荧光颜料的透明塑料材料的光滑表面放置在边缘下方并与光源相对。条带片材部分中的颜料暴露于边缘外部的光源发荧光，产生与暴露于光源的片材的面积成比例的光量。该光能在片材表面之间传播到片材的边缘。光电敏感装置可操作地与片材的边缘相关联，以产生与荧光产生的光能量成比例的电信号，该信号可被放大以控制用于重新定位条带的功率装置。

摘要： Presence or location of an object is detected or movement thereof is controlled by projecting light at the location where the object or the edge thereof is expected and detecting transmitted or reflected light by a photoelectric responsive device. The photoelectric responsive device is connected to a circuit which actuates either an indicator of the location of the object in the illuminated field or actuates mechanism for readjusting the position or direction of the movement of the object. The effect of variations in ambient or extraneous light or flashes of light is overcome by pulsing the projected light at a suitable rate and causing the photoelectric response circuit to be responsive only to electrical currents having the same pulse wave form as the light source with means for synchronizing the electric detector circuit with the light source.

摘要： Safety shutoff valve structure and method, wherein the valve is a ball valve sealed by an annular flexible seal urged into engagement with the valve by a garter spring whereby on opening the valve substantially no pressure drop is developed across the valve, and wherein a compression spring is provided for urging the valve stem in one direction to close the valve, a lever and detent means therefor are connected to the valve stem by a solenoid actuated spring clutch responsive to a predetermined condition whereby on rotating the valve stem to place the valve in an open position, the valve is maintained in the open position until occurrence of the predetermined condition. The spring clutch is operated with a uniform force not dependent on the valve opening torque or compression spring strength and the spring clutch is engaged with a force greater than the actuating force on moving the valve to an open position.
