摘要： A shear seal assembly (80) for sealing between two members (22, 36) having limited relative motion therebetween has an inner sleeve (86), an outer sleeve (88), and an elastomeric member (90) connecting the sleeves (86, 88). The inner sleeve (86) is in a press fit relationship with one of the members (22) and the outer sleeve (88) is in a press fit relationship with the other of the members (36). Thrust members (92, 93) extending radially outwardly along the sides (94, 96, 98, 99) of the seal assembly (80) control distortion thereof and prevent damage thereto. A protective member (93, 100) prevents the ingress of external contaminants and abrasives into the area to be sealed.

摘要： A system for transporting a highly corrosive liquid solely by pressure differential without the need of mechanical pumps for transporting the corrosive liquid. The system includes a source of gas under pressure (78, 82) and first and second corrosive liquid reservoirs (22, 24) connected in parallel to the source via a valve (80) such that one or the other, but not both, may receive pressurized gas. A valve (20) connects one or the other, but not both, of the reservoirs to a point of use (10) of the corrosive liquid and is specifically designed for connecting the reservoir receiving the pressurized gas to the point of use. A valve (36) receives corrosive liquid from the point of use and directs the same to one or the other, but not both, of the reservoirs, and is specifically designed to provide the corrosive liquid to the reservoir not then receiving pressurized gas from the source. Air displaced from the reservoir receiving the corrosive liquid is directed to a scrubber (72) and then returned to the pressurized gas source for subsequent reuse.
摘要翻译：仅用压差传送高腐蚀性液体的系统，不需要用于输送腐蚀性液体的机械泵。该系统包括压力源（78,82）和通过阀（80）并联连接到源的第一和第二腐蚀性液体储存器（22,24），使得一个或另一个但不是两者可以接受加压气体。阀（20）将储存器中的一个或另一个（而不是两个）连接到腐蚀性液体的使用点（10），并且被专门设计用于将接收加压气体的储存器连接到使用点。阀（36）从使用点接收腐蚀性液体并将其引导到储存器中的一个或另一个而不是两个储存器，并且被特别设计成将腐蚀性液体提供给储存器，而不是从该储存器接收加压气体资源。从接收腐蚀性液体的储存器移出的空气被引导至洗涤器（72），然后返回到加压气体源以便随后重新使用。

摘要： To push arms of a conventional bulldozer assembly are mounted on a track roller frame of a track-type tractor by bearing assemblies, each including a pair of bearing caps. One of the bearing caps is welded to the push arm, thus requiring that it be cut-off upon replacement thereof. In addition, the bearing cap welded to the push arm must be selectively hardened to avoid stress cracking in the heat affected zone of the weld. This invention overcomes the above problems by providing a bearing assembly (16) which includes a pair of separable first and second bearing caps (17, 17') which are secured together and to the push arm by common fasteners (28).
摘要翻译：传统推土机组件的推动臂通过轴承组件安装在轨道式拖拉机的履带轮架上，每个轴承组件包括一对轴承盖。其中一个轴承盖焊接到推臂上，因此要求在更换轴承盖时切断。此外，焊接到推臂上的轴承盖必须选择性地硬化，以避免焊缝热影响区域的应力开裂。本发明通过提供一种轴承组件（16）来克服上述问题，轴承组件（16）包括一对可分离的第一和第二轴承盖（17,17'），所述可分离的第一和第二轴承盖（17,17'）通过共同的紧固件（28）固定在一起并且到推动臂。

摘要： In some piston engines a pressurized fluid which is delivered to a main receptor (16) is also delivered to a secondary receptor (18) from which it is directed to cool the pistons. During engine startup and low idle operation such cooling is unnecessary, and further, it is desirable to provide as much fluid flow as possible to the main receptor (16), which is generally the main lubricating manifold (16) of the engine. Herein, delivery of the pressurized fluid to the secondary receptor (18) is prevented until the fluid pressure in the main receptor (16) reaches an initiating value (A). The main receptor (16) thus receives added fluid flow at startup and during low idle operation, while adequate piston cooling is provided at normal operating speeds.
摘要翻译：在一些活塞式发动机中，输送到主受体（16）的加压流体也被输送到二级接收器（18），从而从其被引导以冷却活塞。在发动机启动和低怠速运行期间，不需要这样的冷却，并且进一步地，期望向主接收器（16）提供尽可能多的流体流，主接收器（16）通常是发动机的主润滑歧管（16）。这里，防止将加压流体输送到二次接收器（18），直到主受体（16）中的流体压力达到起始值（A）。主接收器（16）因此在启动时和低空闲操作期间接收添加的流体流量，同时在正常操作速度下提供足够的活塞冷却。

摘要： Fuel injectors operate in a high temperature environment associated with fuel combustion. Temperature control of the nozzle end of fuel injectors is advantageous. An improvement is provided in controlling the temperature of a fuel injector (12) adjacent the nozzle end (36) by conducting fluid toward and away from the nozzle end (36) by way of passages (52, 54) formed in a retainer sleeve (48) associated with the fuel injector (12).

摘要： An improved ripper assembly (10) wherein a ripper shank (19) is mounted to the beam (11) of a tractor by a clevis pin (22) so as to minimize side forces acting on the shank pin (25). The vertical axis of the clevis pin may be aligned with the distal end (34) of the ripper tip (21) and the horizontal axis (24) of the shank pivot pin (25). The impact surfaces (28, 29) of the impacting mechanism (18) and shank (19) preferably define a plane of abutment in which lies a radius (30) from the horizontal shank pivot pin axis (24). This plane is further preferably accurately perpendicular to the ripper tip axis (31) extending perpendicularly to the radius (30). The arrangement provides a free pivoting action of the ripper assembly about the vertical axis of the clevis pin so as to effectively minimize side loads for improved extended life of the ripper assembly (10).

摘要： In a crawler vehicle (10), a support bar (25) to main frame (12) connection is provided which has adequate shear strength and flexibility. The support bar (25) is shaped (50) in line with the main frame beams (38, 40) so that the main frame beams (38, 40) seat therein. The junctions between the support bar (25) and main frame beams (38, 40) are welded (54, 56) together. Angled plates (60) are fitted between each side (46, 48) of each main frame beams (38, 40) and the support bar (25), which angled plates (60) are welded (68) to the beams (38, 40) and to the hardbar (25). The angled plates (60) bridge (66) the longitudinal welds (54) between the support bar (25) and the beams (38, 40) of the main frame (12) to lend some flexibility to the junction therebetween.
