A check detector for the neck and finish portion of glass bottles is disclosed. The check detectors comprises means for rotating glass bottles successively conveyed to a fixed position and a slide block which can change position freely in the width direction and vertical direction of the bottle. A plurality of light emitters for illuminating the neck and finish potion of the glass bottle are mounted to the slide block. The light by from the plurality of the light emitters is converged to the illuminated region from difference directions, and there are a plurality of light receivers equipped with light sensors for detecting the light reflected by checks in the neck and finish portion of the bottle, the light reflected by the mold seam formed at the neck and finish portions, and the directly transmitted light passing through the neck and finish portion, via lenses mounted to the slide block. There is a light emitter control section for constantly operating a plurality of light receivers in the light emitting condition so that the reflected and direct light are input as data, wherein each of the light receiving elements are divided so as to correspond to the vertical position of the neck and finish portion. The data inputted as light reflected at the seam and the data inputted as the direct light transmitted through the neck and finish portions are deleted.

A rotary actuator is disclosed which changes the angular position of the rotary valve which is used to determine the attenuation presented by a shock absorber. The rotary actuator is disposed within a cylindrical piston rod of the shock absorber, and comprises a power transmission mechanism for driving the rotary valve for rotation between a first and a second position within a given range, a d.c. motor for driving the mechanism, a first stop mechanism for selectively stopping the rotation of the motor at a third position which is situated centrally within the given range, and a solenoid assembly for making the first stop mechanism operative. These components are disposed within the cylindrical piston rod in the sequence named from below to above. The power transmission mechanism includes a second stop mechanism which prevents the rotary valve from rotating outside a first and a second location which determine the given range.

An electromagnetic control valve is provided with a housing having an inlet and two outlets extending through the wall of the housing. A valve member is mounted in spaced relation from each outlet opening on a resilient member for movement into and out of engagement with a valve seat surrounding the outlet opening. An elongated valve actuator is pivoted at its mid-point between the two valve members and is provided with a projection adjacent each end disposed in contact with a respective valve member. A spring normally biases the valve actuator about its pivot point to bias one of the valve members into engagement with its associated valve seat. An electromagnet is located on the opposite side of the valve actuator from said one of said valve members to pivot the valve actuator against the force of the spring.

A process for treating waste water of flue gas desulfurization comprising successively adjusting the pH of the waste water to 5 or less, bringing the waste water into contact with a column packed with fine particles of iron, flocculating the waste water, removing formed flocs from the waste water by solid-liquid separation, and optionally, bringing the remaining waste water into contact with a resin for COD adsorption, successively. Hazardous substances, such as oxidative substances, peroxosulfuric acid, iodic acid, heavy metals such as copper and lead, and non-metallic substances such as selenium compounds and fluorites, can be removed simultaneously and efficiently from the waste water of flue gas desulfurization containing these hazardous substances by using the process which is a simplified waste water disposal system. Water having an excellent quality for a long time can be obtained by the process because deterioration of a resin for COD adsorption by oxidative substances such as peroxosulfuric acid and iodic acid can be prevented. Thus, an easy and efficient process for treating waste water of flue gas desulfurization can be provided.
摘要:
A suspension pressure control system applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with a suspension from the valve. A height and a lateral acceleration of a car body as well as a steering angular velocity are detected. A deviation of the height from a target height is calculated. The suspension pressure is adjusted responding to the deviation and a change rate thereof. Also a correction value is calculated on the basis of the lateral acceleration for adjusting the suspension pressure responding to the correction value and a change rate thereof. Proportional coefficients for converting the change rate of the deviation and the change rate of the correction value to pressures to be corrected are corresponding to the steering angular velocity.
摘要:
A pressure control valve delivers a pressure which is proportional to a current level chosen to energize a solenoid therein to a shock absorber of a suspension. A spool in the valve has an annular groove for communicating an output port to a high pressure port or a low pressure port selectively. There are conical surfaces or inclined surfaces at edges of lands adjacent to the groove, which incline from annular surfaces of the lands toward the bottom of the groove. The inclined surfaces slow down a change of the flow rate from the high pressure port to the output port and from the output port to the low pressure port when the annular groove communicates with the high pressure port and the low pressure port respectively.
