Abstract: The runners of the intake manifold between the fuel-air mixture device and the valve ports of the head of an internal combustion engine are tuneable to a particular engine and/or RPM range either manually or automatically by moving at least one wall of each runner inwardly and outwardly to correspondingly decrease and increase the flow through cross-sectional area along the runner. Manual adjustments may be made for particular running conditions or engine component combinations, and automatic adjustments may be made in correspondence with changes in engine speed during operation by vacuum controls, throttle linkage, or electrical controls, for example.

Means coupled to the command signal outputs implement the commands.

Abstract: The square game board has a peripheral pattern of alternating playing squares and non-playing squares in a checker board pattern together with a central four-sided ring of playing squares surrounding a central-most non-playing area. Die is provided to chance control the number of moves and forward or backward direction of moves in the peripheral area and/or the number of moves in and the peripheral direction within the ring, only if an opponent's piece cannot be jumped, which jumping is mandatory. Occupation of the four corners of the ring will permit removal of any pieces from the players back row, with the object being to remove all of your pieces or occupy only the four corners of the ring.

Abstract: In a stone cutting machine having a cutting chain rotated by a motor and a separate power feed for the machine, the power consumption of the drive motor is monitored. When the power consumption falls below a minimum, a control signal is generated to increase the feed, and when the power consumption exceeds a fixed maximum, a control signal is generated to decrease the feed. In generating the control signal, the power consumption is scanned only over a pre-determined period, which for power consumption beneath the minimum is approximately twice as long as for the power consumption above the maximum.

Abstract: Monochromatic light emitted from a monochromator is split into two light beams. These light beams are detected by a photodetector and converted into corresponding electric signals after having been transmitted, respectively, through a sample to be analyzed and a reference placed in the respective beam paths. The signal corresponding to the light beam transmitted through the sample and the signal corresponding to the light beam transmitted through the reference are converted into digital signals which are subsequently stored in respective digital storages or memories. The signal corresponding to the light beam transmitted through the reference is compared with a value in a predetermined range. The resultant value is then converted into an analog signal for operating a sensitivity regulator thereby to adjust the sensitivity of the photodetector. Thus, the signal corresponding to the light beam transmitted through the reference (reference light signal) is so controlled as to lie in a predetermined range.

Abstract: Prior to bringing a fluid machine to the condition of spinning reserve for practicing a phase modifier operation or for producing a so-called standby condition which permits immediate switch-over to a power-generating or pumping-up operation, the water level in a runner chamber is forced down by supplying compressed air, and then the runner is driven to rotate in compressed air atmosphere. In this process, the water in a casing is gradually discharged at a rate which is commensurate with the rate of supply of the compressed air so as to thereby prevent leaking of the water in the casing from a guide vane.

Abstract: In a molding apparatus employing opposed endless belt conveyors to mold a non-rigid material into a rigid material, the problem of one conveyor being driven at a slightly greater speed than the other conveyor to produce harmful shear stresses within the molded product is avoided by driving both conveyors at generally the same speed during start-up until the rigid product extending between the two conveyors will tend to drive the slower conveyor at the speed of the faster conveyor, at which point the drive for the slower conveyor will be disconnected. One-way clutches may be placed in the drive of both conveyors so that it does not matter which conveyor is slower, or a one-way clutch may be placed in the drive of only one conveyor and the other conveyor constructed so that it will inherently tend to run faster than the one conveyor, or a selectively releasable coupling, such as a clutch, may be placed in the drive of one conveyor so that the drive of the one conveyor may be disconnected.
