摘要： Apparatus for making stencils of the type having a rectangular frame and a woven fabric stretched upon and affixed to the frame for use in a screen printing machine has a table which supports four rows of neighboring fabric stretching devices surrounding a rectangular portion of the upper side of the table. Each stretching device has a support the underside of which abuts the upper side of the table, and a double-acting hydraulic or pneumatic cylinder and piston unit pivoted to the support and having a piston rod extendable toward and retractable away from the frame at the rectangular portion of the upper side of the table. The free end of each piston rod carries tongs having a pair of fabric-engaging jaws which stretch the fabric during retraction of the respective piston rod.

摘要： An article adapted to be dispensed from aircraft onto large surface areas for the purpose of beneficially influencing the environment which employs a hollow casing having at least one opening whereby when at least one item for producing such influence is stored in the casing, the item will be released through the opening to the adjacent surface areas to initiate the influence on the environment after the casing is in landed position. At least one of the items is disposed in the casing. A structural arrangement is secured to the casing to prevent the casing when in landed position from being in direct contact with the surface area, thus shielding the item from the adverse influence of local weather.

摘要： The invention relates to an improved process and apparatus to produce a filter cake formed by retained solids collected on a filter cloth during filtering. Accordingly, the filter cake is sub-divided into a plurality of filter cake elements which are kept separate from each other at predetermined distances. Further, impermeable zones on the filter cloth are formed around the filter cake elements. The filter cake elements and the impermeable zones are of a size that the filter cake elements can freely contract in any plane without cracking, while the filter cloth between the filter cake elements is covered by the impermeable zones.
摘要翻译：本发明涉及一种改进的方法和装置，用于在过滤期间产生由滤布上收集的残留固体形成的滤饼。因此，将滤饼细分成多个以预定距离彼此分离的滤饼元件。此外，滤饼周围的不透气区域形成在滤饼元件周围。滤饼元件和不渗透区域的尺寸使得滤饼元件可以在任何平面中自由地收缩而不会开裂，同时滤饼元件之间的滤布被不可渗透区域覆盖。
