摘要： An electro-hydraulic (EH) actuator for converting electrical inputs into hydraulic output signals is described. The actuator features a pressure balanced design which permits operation at high absolute pressures without performance degradation. Internal portions of the EH actuator are filled with a non-conducting fluid, while a flexible diaphragm provides a movable interface between the fluid and the environment in order to equalize the internal and external pressures on the actuator.

摘要： In accordance with the present invention, an impulse generator of high portability is provided using a pair of guillotinized, separately activated hammer/anvil sub-assemblies. Since each sub-assembly is horizontal positioned, say in contact with the earth from a position below the wheel of an exploration truck, the equivalent of the "flying blade" of a guillotine, i.e., a weighted hammer element, must be provided with horizontal movement. This is done by tensioning a plurality of springs attached between the hammer element and a rectangular main frame.During cocking and release of the hammer, the explorationist is provided with a series of visual signals in the form of deactivated and activated panel lights. These signals are automatically provided by controller means of the present invention. Release of the cocked hammer, however, is operator controlled for safety reasons say by activation of a latching means attached to the main frame of the assembly.
摘要翻译：根据本发明，提供了一种具有高便携性的脉冲发生器，其使用一对被切断的单独激活的锤/砧座子组件。由于每个子组件是水平定位的，例如从探测车的车轮下方的位置接触地球时，相当于断头台的“飞刀”（即加权锤击元件）必须设有水平运动。这是通过张紧附接在锤元件和矩形主框架之间的多个弹簧来实现的。在锤击和释放锤子期间，勘探者提供一系列以失活和激活的面板灯的形式的视觉信号。这些信号由本发明的控制器装置自动提供。然而，由于安装在组件的主框架上的闩锁装置的活动，出于安全原因，释放锤形锤是操作者操作的。

摘要： Two or a larger even number of compressional wave producing vibrators are symmetrically disposed in two groups on opposite sides of a profile line in closely spaced relationship. The vibrators are energized by the same (or identical) sweep signals, the signals to one vibrator (or group) on one side of the line being separated in phase by 180.degree. from the signals to the vibrator or group on the other side. P-wave components are thereby cancelled, leaving the shear waves to be propagated.
摘要翻译：两个或更大的偶数个压缩波产生振动器以紧密间隔的关系对称地分布在轮廓线的相对侧上。振动器由相同（或相同）的扫描信号激励，信号到线路一侧的一个振动器（或组）相对于信号与另一侧的振动器或组相位180°分离。因此P波分量被消除，使剪切波传播。

摘要： A method and apparatus for improving the power output of a seismic vibrator are provided. Compliant elements with variable stiffnesses are interposed between and connected to the holddown mass and the baseplate. When the compliant elements have a first stiffness, the vibrator-earth system has a first resonant frequency. When the compliant elements have a second stiffness, the vibrator-earth system has a second resonant frequency. During sweep, the compliant elements are set on the first stiffness until the vibrator has passed through the first resonant frequency; then the compliant elements are changed to their second stiffness and the sweep continues through the second resonant frequency.

摘要： A high pressure seal is formed between a stationary piston and a reciprocating cylinder. The seal includes a sleeve which has an inner diameter dimensioned to permit the cylinder to slide freely over the piston rod, the sleeve being in rigid contact at one end to the cylinder and the other end to an end plate surrounding the piston and closing the end of the sleeve. A bleeder port communicates with the outer surface of the piston rod, through the piston rod, and terminates at a low pressure supply. Bleeder grooves are formed around the inner wall of the sleeve. A first bleeder groove is positioned in the inner wall of the sleeve at the mid-stroke position of the piston with second and third bleeder grooves positioned at each extreme position of the piston stroke in the inner wall of the sleeve. A plurality of pressure drop grooves is formed along the inner sleeve diameter such that the hydraulic fluid passing from the cylinder into the sleeve will gradually drop in pressure as it moves toward the end plate. Pressure relief at the end plate seal is provided by the hydraulic fluid accumulating in the bleeder grooves where it is removed through the bleeder port.
摘要翻译：在静止活塞和往复缸之间形成高压密封。密封件包括具有内径的套筒，该内径的尺寸被设计成允许气缸在活塞杆上自由滑动，套筒在一端与气缸刚性接触，而另一端与围绕活塞的端板关闭，的袖子。泄放口与活塞杆的外表面通过活塞杆连通，并以低压供应端接。在套管的内壁周围形成有渗液槽。在活塞的中间位置处，第一泄放槽定位在套筒的内壁中，其中第二和第三泄放槽定位在套筒的内壁中活塞冲程的每个极限位置。沿着内套筒直径形成多个压降槽，使得从缸体进入套筒的液压流体在向端板移动时将逐渐降低压力。在端板密封件处的泄压由积聚在泄放槽中的液压流体提供，其中通过泄放口移除。
