摘要： A helicopter tail rotor disposed on a crane for stabilizing a load suspended from the crane boom during a hoisting operation. The tail rotor is secured to a hoisting platform suspended from the upper end of the boom, the rotor blades being manually or automatically adjusted for turning the load horizontally in either direction such that the load is both stabilized during hoisting and easily directed to its assigned location. Alternately, the tail rotor is directly secured to the upper end of the boom such that the boom and crane body can be easily rotated about a fixed base, thereby avoiding the need for ring and pinion gears at the base of the crane, or reducing the load on such gears if they are used.
摘要翻译：安装在起重机上的直升机尾部转子，用于在起重作业期间稳定悬挂起重机吊臂的载荷。尾部转子被固定到从起重臂的上端悬挂的起重平台上，转动叶片被手动或自动地调节，以便在两个方向上水平地转动负载，使得负载在起重期间均稳定并且容易地被引导到其指定位置。或者，尾部转子直接固定在起重臂的上端，使得起重臂和起重机主体能够容易地围绕固定的基座旋转，从而避免了在起重机的底部需要环形和小齿轮，或者减少如果使用这些齿轮，则会加载。

摘要： A transport rig for moving a heavy load, such as a concrete modular building unit, includes a pair of load-carrying frames supporting the front and rear ends of the load. Front and rear hydraulic cylinders are secured between corresponding front and rear load-carrying frames and running gear at the front and rear, respectively, of the transport rig to support the load above the ground. An adjustable cable extends from one load-carrying frame to the other beneath the load and is drawn tight to secure the load-carrying frames together. The opposite ends of the cable are connected to a pair of power-operated winch drums on one loadcarrying frame, and the cable is reeved in a closed loop around guide means on the front and rear load-carrying frames. The winch drums can be power-operated to shorten the effective length of the cable and pull the load-carrying frames tightly against the front and rear ends of the load. The load is removed from the transport rig by contracting the front and rear hydraulic cylinders to lower the load-carrying frames to place the load on a foundation or the like. The load-carrying frames may be shifted laterally in either direction to properly position the load directly above the foundation before the load is finally placed on the foundation. The cable is then disabled so the loadcarrying frames can be separately removed from the ends of the load.
摘要翻译：用于移动重负荷的运输装置，例如混凝土模块化建筑单元，包括一对支撑负载的前端和后端的承载框架。前后液压缸分别固定在运输工具的前后负载框架和行走齿轮之间，以支撑地面以上的负载。一个可调节的电缆从一个承载框架延伸到负载下的另一个承载框架，并被拉紧，以将承载框架固定在一起。电缆的相对端连接到一个承载框架上的一对动力操作的绞盘鼓上，并且电缆围绕前后承载框架上的导向装置围绕闭环。绞车鼓可以动力操作，以缩短电缆的有效长度，并将承载框架紧紧地压靠在负载的前端和后端。通过使前后液压缸收缩以降低承载框架以将负载放置在基础等上，从运输工具卸载负载。承载框架可以沿任一方向横向移动，以在负载最终放置在基础之前将负载正确地定位在地基的正上方。然后电缆被禁用，因此承载框架可以从负载的端部分开移除。

摘要： A pair of precast concrete building units are joined together to form a modular concrete house. Each concrete building unit includes a floor slab, upright load-bearing exterior walls joined with the perimeter of the floor slab, and a sloping roof cast integrally with the tops of the exterior walls. The building units are arranged so that the roof of each unit slopes upwardly toward the other unit, with the elevated ends of the roofs meeting to form an inverted V-shaped pitch roof. Interior walls are cast integrally with the exterior walls and the roof to divide the building units into separate rooms. The bottoms of the interior walls are spaced above the floor slab so that no loads are transmitted to the floor slab by the walls, and plumbing and wiring are run through the space between the bottom of the interior walls and the floor slab. A reinforcing cage formed from welded wire mesh is embedded in each exterior wall.

摘要： The rotary desalting device relates to a machine for purifying or concentrating fluids containing dissolved materials. The rotary desalting device of the present invention utilizes one or more high speed, thin rotating discs as heat transfer surfaces between a boiling and condensing fluid. The disc or discs are rotated at such high speed that the extreme centrifugal force of hundreds of times the force of gravity reduces the insulating water film to a micro-thin liquid film wherein greatly improved heat transfer coefficients are obtained. Provided in the rotating disc chamber housing is a centrifugal liquid seal to separate the boiling and condensing chambers which is combined with a naturally pressurized fluid discharge at the disc periphery. The rotary desalting engine of the present invention also incorporates other unique and novel components such as an easily cleanable tri-liquid counter-flow spiral heat exchanger and degasser devices to prevent dissolved gas from accumulating in and blocking the purifying system.

摘要： A novel heat exchanger is formed by using alternating smooth and dimpled, thin, thermally conductive strips which are wound in a spiral to form the closed passageways for fluid between the strips and retain between an outer retaining and fluid distribution ring and an inner retaining and fluid distribution ring. The strips have means for sealing and insulating the periphery in a fluid tight manner. The dimpled strips have dimples extending from each side of the strip the size determining the fluid capacity of the passageways. The smooth and dimpled strips are used in pairs enabling two, four, etc., fluids to be passed either in concurrent or counter-current flow so as to provide an efficient heat exchanger which may be easily taken apart and cleaned for good service.

摘要： Concrete rooms, each having an integrally cast top segment, consisting of a top panel and three sidewalls, and a precast floor segment, secured to the top segment during its integral casting, are stacked on top of one another to form a rigid structure of multiple floors. The rear ends of the rooms have integrally cast cantilevered overhangs such that when the rear ends of two stacks of rooms are positioned adjacent one another the cantilevered overhangs form floors and ceilings for the corridors defined by the space between the stacks. Each stack of rooms consists of an alternating arrangement of long and short rooms, each short room having a locking ridge at its forward end for locking into an opening formed across the forward end of a corresponding longer room.
