摘要： Process and apparatus for preparing a substantially uniform, gas-containing cement slurry by directing two pressurized streams of a gas-containing hydraulic cement slurry to a common in-line focal point in a generally opposed fashion so that good mixing is achieved by the contact of the two streams. The process is particularly adapted for use in preparing "foamed" cement slurries for cementing subterranean voids such as well boreholes, groutholes, natural cavities and similar voids.

摘要： This disclosure is directed to a radioisotope photoelectric generator for producing electrical energy. The construction of the generator is similar to that of a well-known storage battery. The generator is composed of alternate layers of high-Z, (high atomic-number) and low-Z(low atomic number) material which are insulated by vacuum or other insulating material. Low-energy photons from a radioactive source interact predominantly with the high-Z material by the photoelectric process, ejecting photoelectrons whose energy extends up to the incident gamma-ray energy E. By selecting the high-Z material thickness to be less than one electron range (at energy E) and the low-Z material thickness to be more than one electron range, there is a net electron transfer from the high-Z plates to the low-Z plates because electrons are emitted predominantly from the high-Z plates and stop in the low-Z plates. After start-up, a potential difference will build up between the high-Z and low-Z plates. An upper limit for this potential difference in kilovolts is the energy E in keV. The high-Z plates are connected together electrically and the low-Z plates are connected together electrically thus forming a "battery. " The "battery" delivers power to an external electrical load, preferably but not necessarily a resistor, whose value is chosen to maximize the power delivered to the electrical load, to yield the voltage desired, to control the temperature of the plates, or a combination of such considerations.
摘要翻译：本公开涉及用于产生电能的放射性同位素光电发生器。发电机的结构类似于众所周知的蓄电池。发生器由高Z，（高原子数）和低Z（低原子序数）材料的交替层组成，通过真空或其他绝缘材料绝缘。来自放射源的低能光子通过光电过程主要与高Z材料相互作用，喷射其能量延伸到入射伽马射线能量E的光电子。通过选择高Z材料厚度小于一个电子范围（以能量E）和低Z材料厚度为多于一个电子范围，存在从高Z板到低Z板的净电子转移，因为电子主要从高Z板并停在低Z板上。启动后，高Z和低Z板之间将产生潜在差异。这个千伏特电位差的上限是keV中的能量E。高Z板电气连接在一起，低Z板电连接在一起形成“电池”。“电池”将电力输送到外部电气负载，优选但不一定是电阻器，其值被选择为最大限度地传递到电负载的功率，产生所需的电压，以控制板的温度，或这些考虑的组合。
