摘要： A lens system for protecting high gain optical systems (eyes or equipment) from high intensity laser radiation includes a second mirror disposed on an exit lens, a first mirror formed by half silvering the inner surface of a focusing entry lens, and a medium such as sugar water containing aerosol particles of three-micron carbon, which induces ionization that will absorb the incoming laser radiation. One binocular embodiment uses the foregoing medium; a second binocular embodiment uses a solid lens material laden with aerosol particles.

摘要： A half hinge paint masking cover for doors, and/or door frames is provided as a one piece body molded of a rigid thermoplastic resin. The device includes two molded half cavities each cavity being connected by a thin flexible membrane of the molded material. The first cavity area covers the back surface area of the hinge barrel and has two half end shields each of which cover half the edge area of the hinge barrel and the exposed edge area of the hinge plate. The second cavity half covers the front surface half of the hinge barrel and has two end shields which cover half the edge area of the hinge barrel. A portion connected to the second cavity half includes a long flat area which covers the exposed face side of the hinge plate. The two half cavities are secured to each other by folding along the flexible membrane and engulfing the door or frame half hinge until pins projecting from tops on one half engage and protrude through holes which are located on tabs on the other half.

摘要： An apparatus for exercising the lumbar and truncal regions of a person. A rigid framework supports two generally horizontal turntables at opposite ends thereof. A person reclines the upper region of his torso on one turntable and lower region of his torso on the other turntable, thereby permitting cyclic bending of the torso and, as a result, working of the paraspinous and associated muscles. An adjustable headrest extends from one turntable, and an adjustable footrest extends from the other turntable. Each turntable may be adjusted toward or away from the other, set at a predetermined tilt with respect to the rigid frame, and set at a predetermined degree of rotational resistance. A cyclic motion driving means and a cycle counter are provided.

摘要： A stretching frame for a fabric material provides for spring mounting of the four frame sides. The frame sides are tubular. At each corner of the frame is a bracket which slides within the adjacent frame tubes. A tensioning device at each end of each of the frame sides may be set to provide an appropriate urging force by tensioning a spring. Each side has a slot for insertion of the fabric edge and a locking rod to hold the fabric edge in place within the slot. The frame may be used for a range of fabric sizes by changing spring length or characteristic used for tension development. In use as a silk-screen, the side forces applied to the fabric during the printing stroke is taken up by the springs such that a minimal amount of distortion is experienced by the fabric and stencil thereon.
摘要翻译：用于织物材料的拉伸框架提供四个框架侧面的弹簧安装。框架边是管状的。在框架的每个角落处是在相邻框架管内滑动的支架。每个框架侧的每个端部处的张紧装置可以设置成通过张紧弹簧来提供适当的推动力。每一侧都有一个用于插入织物边缘的槽和一个锁定杆，以将织物边缘保持在槽内的适当位置。通过改变弹簧长度或用于张力发展的特性，该框架可用于各种织物尺寸。在作为丝网使用时，在印刷行程中施加到织物的侧向力被弹簧吸收，使得织物和模板在其上经历最小量的变形。

摘要： A compact attic mounted solar heating pack assembly includes an enclosed sheet metal plenum fixedly hung by straps from the attic rafters at the apex of north and south facing roofing sections. An electric powered blower fixed to the plenum has an air inlet open to the attic interior below the south facing roof section. An air outlet of the blower opens directly to the plenum interior. A plurality of flexible ducts are coupled to respective air outlets within the plenum at one end with their opposite ends terminating in diffusers mountable within holes formed within the underlying ceiling for delivering air from the plenum chamber directly to the building interior below the attic floor. A first normally open cooling thermostat is mounted within the attic at the apex, beneath the south facing roof section. A plastic heat barrier is hung from the ridge pole and extends well below the plenum chamber to trap heated air within the section of the attic beneath the south facing wall. A second heating thermostat is mounted within the building interior below the ceiling and preferably on an interior partition wall and is series connected with the blower motor and the first attic mounted thermostat and connectable to a source of electrical current. The normally open thermostat closes when room heat is needed and the temperature in the attic is above 70 degrees to provide an effective independent supplementary heating unit for the building.

摘要： A lens includes a medium which absorbs laser radiation that may be harmful to the eye or other high gain optics, raising its temperature and thereby changing its index of refraction, which causes a phase change in the radiation passing therethrough. The medium may be periodically bounded by thermal sinks, thereby providing a periodic differential in temperature rise, may be provided in a length which varies periodically or may have a density of absorbing material which varies periodically, thereby to have a periodic absorption characteristic. The periodicity, which may be regular or random, provides a periodic variation in total phase change, which causes interference (thermal blooming) that disperses the radiation sufficiently to lower the intensity at the retinal spot below that which would cause damage. Eyeglasses with mutually perpendicular periodicity provide degraded vision of useful images while being protected from harmful radiation.

摘要： A pair of U-shaped sheet metal brackets are fixably mountable to the rear vertical wall of a power lawn mower deck to opposite sides of the deck or to the top wall of the deck with the open ends facing end other. Bent wire rod angle arms have their free ends of arm first branches pivotably mounted to the base of the U-shaped sheet metal brackets for pivoting internally of the bracket legs limited to contact with the legs of the brackets and their other branch has ends fixed to an axle rotatably supporting a roller for rotation horizontally about its axis and between the angle arm branches at the rear of the rotary power mower. Pivoting of the angle arms limits vertical travel of the roller to several inches to prevent the operator's foot from being projected relatively beneath the mower deck and into the path of the rotating blade of the power mower. Changing the angle of inclination between the branches of the wire rod angle arms permits alternate mounting of the U-shaped brackets to the rear wall or top wall of the mower deck.
摘要翻译：一对U形的金属板支架可固定地安装在动力割草机甲板的后垂直壁上，到达甲板的相对两侧或甲板的顶壁，敞开的端部面向另一端。弯曲线杆角臂具有臂的自由端第一分支可枢转地安装到U形金属板支架的基部，用于在支架腿内部枢转，限制其与支架的腿接触，并且其另一分支具有固定到可旋转地支撑辊子的轴线，用于围绕其轴线水平旋转并且在旋转割草机后部的角度支臂之间。角度臂的旋转将滚筒的垂直行程限制到几英寸，以防止操作者的脚相对于割草机甲板下方投影到割草机的旋转叶片的路径中。改变线杆角臂的分支之间的倾斜角度允许将U形支架交替地安装到割草机甲板的后壁或顶壁。
