摘要： A greenhouse over an agricultural bed or the like comprising a rotating structure. At least one window in said structure lies within a generally parabolic trough surface. The window can both transmit and reflect solar energy. A heat collector is positioned along the parabolic focus of the window. Solar energy is transmitted through the window to provide instantaneous heating of greenhouse and solar energy is stored after it is gathered at the collector for heating the greenhouse when direct solar energy is no longer available.

摘要： An improved joist hanger for supporting steel, wooden or other joists from beams, such as I-beams, wherein a separate bracket is attached at a distance from the beam to each of a pair of conventional joists abutting opposite sides of a conventional girder or beam, and a strap with its ends fastened together links the two brackets over the beam so that both joists are supported vertically by the beam and continually pulled toward it to improve the load distribution of the joists as well as to generally improve the support characteristics of a floor or other structure comprised of such joists and beams.

摘要： A steam boiler (14) is situated on a tower (16) at the center of concentric tracks (17), (18), and (19). Poles (21) and (23) have wheels (25) running on the tracks. The poles are kept upright on the tracks with guylines (35) and struts (31) and (33). The poles carry frameworks (24) with mirrors (12) attached to them. As the earth turns, the poles move along the tracks, keeping the mirrors on the opposite side of the boiler from the sun and keeping sunlight focused approximately on the boiler. As the poles move, the frameworks pivot to fine tune the focusing. Each framework pivots about a horizontal axle (26) of the framework and about the vertical axis of one of the poles (21). Hydraulic cylinders (66) and (70) in series circuits (82) and (78) respectively pivot the frameworks collectively. The frameworks are arranged so the power needed to pivot the frameworks is the same on windy days and calm days. At night and when storms approach, the poles move to closely-spaced tracks (20) where the frameworks form a protective shell (38), (40), (41) and (42) around the mirrors.
摘要翻译：蒸汽锅炉（14）位于同心轨道（17），（18）和（19）中心的塔架（16）上。极（21）和（23）具有在轨道上运行的轮（25）。铁杆保持直立在轨道上，带有黄瓜（35）和支柱（31）和（33）。杆带有框架（24），后视镜（12）连接到它们上。随着地球转动，两极将沿着轨道移动，将反射镜保持在与太阳相反的一侧，并保持阳光聚焦在锅炉上。当杆移动时，框架枢转以微调聚焦。每个框架围绕框架的水平轴（26）和围绕一个极（21）的垂直轴线枢转。串联回路（82）和（78）中的液压缸（66）和（70）分别使框架集体摆动。这些框架的安排是，在大风日和平静的日子里，摆放框架所需的力量是相同的。在晚上，当风暴接近时，两极移动到紧密间隔的轨道（20），其中框架形成在镜子周围的保护壳（38），（40），（41）和（42）。

摘要： An adjustable file handle for files is disclosed. The adjustable file handle comprises a first means which engages the sides of the file substantially adjacent its forward end and above the surface of the teeth of the file which will be in contact with a workpiece. Included with the first means is a hand gripping means for applying pressure to the forward end of the file against the workpiece in a downwardly and outwardly direction. A third means is provided which engages the sides of the tine of the file substantially adjacent the end of the tine and also above the bottom surface of the tine so that contact with a workpiece is avoided. Secured to the third means is a handle means for applying pressure to the tine end of the file against the workpiece in a downwardly and outwardly direction. Another means which is engagable with the first means which engages the forward end of the file and the third means which engages the tine end of the file for applying tension between the first means and the third means is provided.
摘要翻译：公开了一种用于文件的可调文件句柄。可调文件柄包括第一装置，该第一装置基本上与文件的与前述工件接触的文件的齿的表面上方的前端接合。包括在第一装置中的是用于在向下和向外的方向上将文件的压力施加到工件上的手抓持装置。提供了第三装置，其基本上接近齿的端部并且还在齿的底表面上方接合文件的齿的侧面，从而避免了与工件的接触。固定在第三装置上的是用于在向下和向外的方向上对文件的尖端施加压力到工件上的手柄装置。提供了可接合文件前端的第一装置和与第一装置和第三装置之间施加张力的文件的末端接合的第三装置的另一装置。

摘要： A method is disclosed for easing stripping of an ingot from a sectional mold without disassembly of the fastened sections, by partially separating the sections during stripping. An improved mold is provided for accomplishing such partial separation of the sections, preferably by translating part of stripping forces applied longitudinally to the mold into a transverse direction, creating a gap between the longitudinal sections. Various means are shown for coaction with movable stripping lugs to apply a separating force to opposed adjacent mold sections.
摘要翻译：公开了一种方法，用于通过在剥离期间部分地分离部分，从而从分段模具中轻松剥离锭而不拆卸紧固部分。提供改进的模具用于实现这些部分的这种部分分离，优选地通过将沿纵向施加到模具的剥离力的一部分平移到横向方向上，从而在纵向部分之间形成间隙。示出了用于与可移动剥离凸耳共同作用以将分离力施加到相对的相邻模具部分的各种装置。
