摘要： A competent permeable communication zone connecting injection and production wells completed in a tar sand which communication zone will be rigid and will not tend to slump or heal may be developed by injecting a fluid in the injection well under such pressure so as to fracture the tar sand formation between the injection well and the production well and circulating a fluid between the injection and production wells which is at a temperature sufficiently low to freeze the water in tar sands. The fluid may contain propping agents to hold the fracture surfaces apart. This procedure will rigidify the hydrocarbon portion of the tar sand formation in the vicinity of the fracture zone as well as freeze the water in the tar sand formation. Once the fracture is established a solvent for the hydrocarbon in the tar sands may be circulated preferably at a temperature below the freezing point of the water in the tar sands to extract the bitumen therefrom.
摘要翻译：连接注入井和生产井的能力可渗透的通信区域可以在焦油砂中完成，连通区将是刚性的并且不会倾向于坍落或愈合，这可以通过在这样的压力下在注入井中注入流体来开发，以便将焦油砂在注入井和生产井之间形成并在注入井和生产井之间循环流体，其温度足够低以冻结焦油砂中的水。流体可以含有支撑剂以将裂缝表面分开。该方法将硬化裂缝区附近焦油砂层的烃部分，并使焦油砂层中的水冻结。一旦断裂成立，焦油砂中的烃的溶剂可以优选在低于焦油砂中的水的凝固点的温度下循环，以从其中提取沥青。

摘要： A focus improver for a concave reflector having a circular cross section. It has an array of plane mirrors diametrically across the mouth of the reflector. The angle of tilt of the mirrors is relative to parallel rays incident upon the reflector, and each mirror has an angle of tilt such that a central parallel ray reflected therefrom will focus at a common location.An application of the focus improver provides a solar energy collector that employs a cylindrical reflector which may be oriented in an east-west direction. The mirrors are thin strips that are coextensive in length with the cylindrical reflector. And, a solar energy utilization device may be located along the focal line that is created.
摘要翻译：具有圆形横截面的凹面反射器的聚焦改进剂。它具有穿过反射器口部的平面镜阵列。反射镜的倾斜角度相对于入射到反射器上的平行光线，并且每个反射镜具有倾斜角，使得从其反射的中心平行射线将聚焦在公共位置。焦点改进剂的应用提供了采用可以在东西方向定向的圆柱形反射器的太阳能收集器。反射镜是与圆柱形反射器长度共同延伸的薄条。并且，太阳能利用装置可以沿着所产生的焦线设置。

摘要： Hereinafter disclosed is methodology and apparatus for converting wide dynamic amplitude range digital data recorded in floating point digital word form, comprising a binary coded mantissa and a binary coded exponent, to an analog signal, or oscillogram, of compressed dynamic amplitude range. The digital word, occupying a number of binary bit positions, is, in algebraic form, .+-.AG.sup..sup.-E ; where A represents the mantissa, or argument, G represents the base, or radix, of the number system used and E represents the exponent. Since the base G is constant at 8, for example, the only binary bits that need to be recorded are those representing the mantissa A and the exponent E. In reconverting the digital data to analog form for making an oscillogram, or wiggle trace, it is proposed to compress the dynamic range and, yet, at the same time avoid introducing serious distortion. Apparatus for performing the aforesaid changes, among other things, is disclosed.
