Abstract: This invention relates to a manually operated partition removal tool for removing a part of a plastic partition between each adjoining pair of a plurality of pairs of chambers provided in a cellular plastic fluid circuit plate to form therein one or more passageways of any configuration when this fluid circuit plate is interposed between and secured to an upper and lower flat cover plate to form a circuit module for fluid distribution from a source of fluid pressure to a plurality of logic control valve devices that may be mounted on one of the cover plates by any suitable means. This partition removal tool comprises a transparent plastic cylindrical member through which extends, as by a press fit, a metallic rod the length of which is such that each end thereof protrudes a short distance from the corresponding face of the cylindrical member. A suitable handle is secured to one end and the opposite end is provided with a slot the width of which is substantially equal to the thickness of the partitions in the cellular plastic fluid circuit plate. The length of this slot is greater than the length of that protruding portion of the metallic rod in which this slot is formed thereby enabling the adjacent face of the cylindrical member to always abut the outer ends of a plurality of partitions in the fluid circuit plate whenever this slot is placed in straddling relation to any selected partition in the fluid circuit plate. When this partition removal tool is so placed that this slot straddles a selected partition in the fluid circuit plate, this selected partition between two adjacent chambers in the circuit plate may be then severed from the circuit plate and removed from between these chambers by the manual exertion of a torque or turning moment in either direction on the handle of this partition removal tool.

Abstract: This invention relates to a pneumatically or hydraulically operated hydraulically lapped control apparatus in which a manually operated control valve device supplies a pneumatic or hydraulic fluid under pressure to the larger end of a differential-type abutment that is moved thereby to operate a spring-returned directional valve device. The operation of this device causes the supply of a hydraulic fluid under pressure from a source of supply of such fluid to a device to be operated thereby and to the smaller end of the differential-type abutment until substantially equal fluid pressure forces are obtained on the opposite ends of this abutment whereupon the spring-returned directional valve is rendered effective to cut off further flow of hydraulic fluid to the device to be operated and the smaller end of this abutment. Thus, a hydraulic fluid under pressure is obtained for operating a device and for effecting a self-lapping operation, the degree of this hydraulic pressure being variable in accordance with the ratio of the areas of the opposite ends of a differential-type abutment.
