    Abstract: A device for distributing waste heat from a heat source evenly across an exterior surface of an enclosure is disclosed. The device includes a first layer of material that has a high thermal conductivity along a first plane. One or more layers of material that include a controlled thermal conductivity along a second plane are connected with the first layer. At least one of those layers has a low thermal conductivity (e.g. a thermal insulating material) in the second plane and that layer is positioned between the heat source and the enclosure so that heat flow through that layer is substantially inhibited in the second plane and a majority of the waste heat is thermally transferred through the first layer along the first plane to the exterior surface where the waste heat is uniformly distributed thereby reducing hot spots on the exterior surface which can cause user discomfort.

    Abstract: A keyboard lighting device is disclosed. In a preferred embodiment, a moving member may be placed in an operating position protruding from the keyboard, or in a retracted position. In the operating position, light is redirected from a light source to the keyboard so that use of the keyboard in dark environments is facilitated. Preferably, when the moving member is in its retracted position, the keyboard light appears to be a key on the keyboard.

    Abstract: Apparatus and method for constructing a manhole collar between an existing manhole cone and a precast manhole ring. The apparatus includes a circular slip form tube, tapered from a larger top diameter to a smaller bottom diameter; at least two support arms, radially extending from adjacent the top of the slip form tube for placement on a support surface, such as a road surface, to hold the tube at a selected height relative to ground level within a manhole cone; and a plurality of fasteners for attachment of a precast manhole ring about the exterior periphery of the slip form tube for supporting the ring at a selected height relative to the manhole cone and the roadway surface. The apparatus may include a concrete spill retention ring, placeable upon the top rim of the manhole cone and around the slip form tube to prevent concrete from entering the manhole cone. The method of the invention includes the steps of supporting the slip form tube upon the roadway surface by the arms; fastening the manhole ring to the tube for proper positioning thereof; leveling the tube and ring; and the pouring of concrete about the slip form tube to form a ring-supporting concrete collar between the manhole cone and the manhole ring.

    Abstract translation: 在现有的井眼锥体与预制井眼环之间构造井眼环的装置和方法。 该装置包括圆形滑动成形管,从更大的顶部直径向较小的底部直径逐渐变细; 至少两个支撑臂,从邻近滑动成形管的顶部径向延伸,用于放置在支撑表面(例如路面)上,以将管保持在相对于井眼锥体内的地平面的选定高度; 以及多个紧固件,用于将预制井眼环附接在滑动成形管的外周边上,用于将环支撑在相对于井眼锥体和道路表面的选定高度处。 该设备可以包括混凝土溢流保持环,可放置在井眼锥体的顶部边缘周围并且围绕滑动形成管,以防止混凝土进入人孔锥体。 本发明的方法包括以下步骤:通过臂支撑滑动管在道路表面上; 将人孔环固定到管上以使其正确定位; 校平管和环; 并将混凝土浇注在滑模管上,以形成孔眼锥体和人孔环之间的支撑环的混凝土环。
