摘要： A polymer concrete which does not shrink on curing includes a mineral aggregate, a hydrated mineral powder and a polymer matrix for binding the aggregate, the polymer being an acrylic, polyester, vinyl ester or epoxy resin. Due to the polymerization and cross-linking heat of reaction or to externally applied heat, the water of hydration of the filler is converted into steam, which is at least sufficient to prevent the concrete from shrinking. The concrete can be used for coating a submerged pipeline by filling a form placed about the pipeline. Another use of the concrete is in plugging a gas or oil well: after injecting the concrete into the well, a casing plug is placed directly above the concrete, and reliance is placed on the wellhole temperature and the heat of reaction for liberating the steam which, during curing, expands the concrete.

摘要翻译： 在固化时不收缩的聚合物混凝土包括矿物骨料，水合矿物粉末和用于结合骨料的聚合物基质，聚合物是丙烯酸，聚酯，乙烯基酯或环氧树脂。 由于聚合和交联反应热或外部加热，填料的水合水转化为蒸汽，其至少足以防止混凝土收缩。 混凝土可用于通过填充放置在管道周围的形式来涂覆淹没管道。 混凝土的另一个用途是堵塞气井或油井：将混凝土注入井后，将套管塞直接放置在混凝土上方，并依靠井眼温度和反应热量来释放蒸汽， 在固化期间，扩大混凝土。

摘要： An ophthalmic instrument for measuring relative pressure of fluid inside an ocular globe, comprising an elongated surgical instrument (61) adapted to penetrate the ocular globe; pressure sensitive means (67, 68) mounted on the instrument for moving in response to relative pressure changes in intraocular fluid; transducer means (65) communicating with the pressure sensitive means for generating a signal in response to movement of the pressure sensitive means; and means for transmitting the signal external of the instrument.
