摘要： A hydraulic system is provided, having a pump, operably connected to a motor. It also comprises a controller-driven hydraulic actuator, operably connected to the pump and a hydraulic valve, operable to direct hydraulic fluid to and from either a rod side or a cylinder side of the hydraulic actuator. Rod and cylinder side pressures are pre-defined based on the instantaneous acceleration or deceleration required. Decelerating the hydraulic actuator could involve maintaining the current pressure in the meter-out side of the hydraulic actuator and decreasing the current pressure in the meter-in side by varying the speed of the pump. Deceleration of the hydraulic actuator could also include decreasing pressure on the meter-in side of the hydraulic actuator at a higher rate than on the meter-out side. Acceleration is achieved using a similar approach.

摘要： Candy box with one-piece liner forming a plurality of transversely extending grooves and partitions having upper horizontal and transversely extending surfaces defining longitudinal margins along the grooves, a plurality of dividers in at least some of the grooves integral with the liner and spaced transversely to define with the groove walls a plurality of cells each adapted to receive at least one piece of a particular type of candy, indicia means on the upper horizontal surfaces individual to each cell to identify a particular type of candy, a box bottom housing the liner having marginal walls extending a predetermined distance above the horizontal partition surfaces, a cover, and a resilient pad having a thickness substantially equal to said predetermined distance for filling the space between the cover and the marginal walls of the bottom above the partitions, with thin-walled candy-receiving cup members in the grooves having downwardly converging side walls normally extending above the partitions for engagement by the pad to be flexed inwardly thereby when the several parts are assembled to additionally resiliently retain the candy pieces protectedly in the box.

摘要： 10,239. Kowlett, W. W. May 2. Pottery.-Relates to supports for pottery in saggers or kilns. Fig. 2 shows a plan and Fig. 1 an elevation of two superposed supports having a flat or dished table a, radial supporting-ridges b, c, d, perforations e, f, g, and legs h, i, j. The upper part of each leg is provided with a ridge l forming a recess k for the recaption of the lower part of a leg of the superposed support. The legs may be provided with other forms of interlocking projections and recesses at the top and bottom. Fig. 5 shows a modified form of support. Specifications No. 3194, A.D. 1862, and No. 6632, A.D. 1898, are referred to.
