    Abstract: For articles such as rectangular or cylindrical containers or cans, a conveyor guide of the chute type has a number of parallel rails affixed to transverse rib members at intervals along the path of the articles, the ribs in one example being hoop-like rectangular frames arrayed to enclose the moving articles with rails on all the lateral sides. The rails are affixed by means of clamping fasteners each of which is secured to the adjacent rib by a bolt piercing the rib normal to the direction of the path. The fastener can rotate on the bolt so as to permit alignment of the rail at an angle to the rib. Thus at bends in the path, or places where the guide twists to change the vertical orientation of the articles, the rails may be smoothly curved to conform to the path without crimping at the fasteners. The rails are made of springy resilient material to assist this effect. The fasteners are relieved, at least on the side facing the ribs, to improve the clamping effect when the bolts are tightened.

    Abstract translation: 对于诸如矩形或圆柱形容器或罐的物品，滑槽类型的输送机引导件具有沿着物品的路径间隔地固定到横向肋构件的多个平行轨道，一个示例中的肋状物是环形矩形框架 在所有侧面上围绕带有轨道的移动物品。 轨道通过夹紧紧固件固定，每个紧固紧固件通过螺栓穿过相对于路径方向的肋条固定到相邻的肋条上。 紧固件可以在螺栓上旋转，以允许轨道与肋成一定角度对准。 因此，在路径中的弯曲处或引导件扭转以改变物品的垂直方向的位置处，轨道可以平滑地弯曲以符合路径而不在紧固件处卷曲。 轨道由弹性弹性材料制成以辅助这种效果。 紧固件至少在面向肋的一侧被释放，以在螺栓拧紧时提高夹紧效果。

    Abstract: A digital sweep generator for digitally generating an analog since wave signal of constant or varying (sweep) frequency, includes means for generating a rate-of-change clock, a slope clock and a sine function, via digital circuits. The rate-ofchange clock determines the rate-of-change in the frequency of a sinewave across a desired range of frequencies for a given time interval. The slope clock occurs at the exact increments selected to produce a given sinewave frequency as determined by the rateof-change clock. That is, if a sweep sinewave signal is desired, the rate-of-change clock is introduced to modify accordingly the means for generating the slope clock. The slope clock is then introduced to the means for generating a sine function to digitally produce the sinewave signal as the function of the input slope clock rate. Each slope clock represents a point on the slope of the generated sinewave, corresponding to equal increments of 360* of a sinewave. Two outputs are provided; a digital word corresponding to the sinewave, and the analog sinewave signal delivered therefrom via a digital-to-analog converter.

    Abstract: A gas operated seismic source has a rigid elongated cylindrical form and includes at least a single, hollow, thick wall barrel along most of the central length thereof, wherein the internal volume defines therein a combustion chamber. The barrel has a plurality of perforations formed along its length of a selected number, size or sizes, and arrangement. An inflatable member is secured at either end thereof about the perforated barrel to enclose the perforations and define accordingly an expandable outer wall about the combustion chamber. The perforated barrel has a substantially constant diameter as does the inflatable member, and the barrel supports the inflatable member when in its collapsed state. Thus the outside dimensions of the entire length of the source are substantially constant to allow the source to be readily forced or ''''planted'''' into and also retrieved from a consolidated or an unconsolidated formation, or to readily allow inserting the source into a predrilled hole in a consolidated formation. Means are provided to introduce a preselected mixture of combustible fuel into the combustion chamber. Upon firing, the burned gases are forced out an exhaust means by the explosion and the subsequent charge of combustible fuel, or the combustion chamber is purged by employing vacuum or pressure.

    Abstract: A pallet that is dimensioned for fully supporting a certain number of cans that are packed in layers, and the layers in an even number of staggered diamond pattern rows, is to be packed with an extra row in each layer. The bottom layer is to be centered on the pallet so that the containers of the edge rows, including the extra row, each overhang beyond the pallet by less than half so as still to be solidly supported. The apparatus accomplishes this packing by moving a set including the extra row of containers along a path above the pallet with the set preceded by a single row and followed by a remainder to permit the set to separate therefrom; and then removing the preceding row before the set is lowered onto the pallet. The containers of the preceding row are then recirculated to the upstream portion of the path to beome part of a subsequent set.
