    • A three wheeled carriage supports an air compressor, a container for reflective glass beads and a primary hose enclosing secondary hoses delivering plural paint components to a spray gun. The three wheeled carriage has a handle bar operable by one person with three switches, one to control the flow of reflective glass beads to a bead spray gun, another to control the flow of paint components to form a stripe by external mix of the paint components and a third to control an angle of turn for a front wheel. A trailer follows the three wheeled carriage, the trailer containing an air compressor and receptacles for two paint components and input into the secondary hoses. Wheeled dollies support the primary hose between the trailer and the three wheeled carriage.
    • 三轮支架支撑空气压缩机,用于反射玻璃珠的容器和包含向喷枪提供多个涂料组分的次级软管的主软管。 三轮托架具有可由一个人操作的手柄,其具有三个开关,一个用于控制反射玻璃珠到珠喷枪的流动,另一个用于通过外部混合的涂料组分来控制涂料组分的流动以形成条纹 以及用于控制前轮的转弯角度的第三。 拖车遵循三轮托架,拖车内装有空气压缩机和两个油漆部件的容器,并输入二次软管。 轮式货车支撑拖车和三轮车厢之间的主要软管。

    • 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.
    • 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。

    • A routing method implemented in the stored programs of a digital computer ich is programmably operated to generate the wire interconnect masks for a two level metallization automated universal array having undefined roadbeds between rows of cells comprised of identical semiconductor device basic units which are further interconnected to provide a particular integrated circuit structure. Conductor routing is provided by a computer aided design system that, among other things, carries out a route analysis process which determines in which roadbed each wire should be tentatively routed in conjunction with generating a routing density profile for minimizing congestion for a particular circuit design and when the roadbed density is exceeded, certain wires are removed under a set of criteria for routing by a pathfinder routing process. Following route analysis, detailed routing and rerouting is performed sequentially by a direct routing process, a greedy channel routing process, and a pathfinder routing process with rerouting being performed after each channel router and pathfinding process. Furthermore, the greedy channel routing process makes a single pass from left to right in all wires which cross successive points simultaneously and, if necessary, deleting a wire or wires which are then rerouted by the pathfinding process.

    • A Method of controlling power generating equipment to coordinate with the demands of heating equipment and cooling equipment that are powered by exhaust gases from the power generating equipment.A feed-forward prediction is produced of the electrical power supply that produces substantially the required exhaust gas output to match the heating and cooling equipment requirements.A composite power production demand error variable is produced that combines all of the heating and cooling demand requirements that vary from the feed-forward prediction;The demand error variable is sent to a proportional integral derivative control element to generate a control variable. The control variable and the feed-forward prediction are combined to produce a setting for the power generating equipment to produce essentially only the gases required to operate the heating equipment and cooling equipment at the desired level.
