Abstract: The method can be applied in the premedical assistance, in the inpatient and outpatient practice in the human and veterinary medicine for the effective treatment of diseases, in particular of diseases of the gastrointestinal, renal and urinary tract, of viral and bacterial infections. By the method the clinoptlilolite mineral is administered in combination with vitamin C. The clinoptiilolite is heat-treated at 150-250 degrees C, sterilized and has particle sizes of the particles of ( 0.1 mm. For the treatment of internal diseases the clinoptilolite is administered once daily at 0.5 to 1 teaspoons (2.5 to 5 g), 30 min to 4 h after meals. For the treatment of gum bleeding, colds, neuralgia, allergies, urticaria, hay fever, contagious diseases such as measles, varicella, rubeola, as well as medicamentous and intestinally intoxication, night wetting, uneasiness and strain, physical and mental fatigue, stress conditions, memory disorders (tendencies to absent-mindedness and forgetting), initial forms of the Alzheimer's disease, Gana, tendencies of diabetes and chronic alcoholism the organism should be cleaned in advance of toxic protein waste products. Then the organism is saturated with vitamin C under control until the satisfaction of its individual needs by periodic vitamin C administration of daily doses of from 0.5 to 5 g. The saturation moment is determined by periodic monitoring of the organism 4 h after each vitamin C administration, until reaching vitamin C level in the urine from 40 to 60 mg %. After the pre-saturation ends, this level is maintained by a vitamin C dose of from 0.1 to 0.5 daily until the restoration of normal anisotropic and isotropic crystalline structures in the patient's urine. In the treatment of other diseases another medicamentous form can be additionally administered depending on the treated diseases. 11 claims, 1 figure

Abstract: 一种形成晶体调谐半导体衬底的方法包括如下步骤：通过提供在Si表面上平行间隔的氧化物墙(2)来确定该Si表面的平行条，在该条上选择性生长第一SiGe层，使得第一位错(3)优先在墙(2)之间的第一SiGe层中延伸，以释放在第一SiGe层中横切于墙(2)的方向上的应变，在第一SiGe层的顶部上生长第二SiGe层以生长超过墙(2)，使得在墙(2)之上的第二SiGe层中优先形成第二位错，以释放在第二SiGe层中横切于第一位错(3)的方向上的应变。这样产生的位错用于在相互横切的方向上释放材料中的应力，同时由于在空间上被分隔而使这两组位错不能发生相互作用。这样，将大地降低了穿透位错的密度和表面粗糙度，因而通过减少导致有源器件中电子散射和使电子移动速度下降的原子晶格破坏增强了虚拟衬底的性能。

Abstract: 1,053,329. Traversing means. ELEKTROMAT VEB. Sept. 8, 1964, No. 36675/64. Heading D1J. A device for traversing wires and the like on to spools 11 comprises two or more pairs of parallel links 2, 3; both links 2, 3 of each pair being pivotally suspended at their upper ends from a fixed member 1 and being pivotally coupled together at their lower ends by a transverse link 4 so as to form an articulated parallelogram-shaped frame, each frame being secured to an adjacent frame by longitudinal beams 5, 7 on one of which there are rotatably mounted two or more guiding rollers 6 or the like for guiding the wires. As shown two of the above described devices are also arranged in side-by-side relationship, two of the parallelogram-shaped frames being linked together by a lead screw 8 connected through a reversing gear 9 to drive means.

Abstract: 1,054,731. Storing liquefied gases. GAZ DE FRANCE-SERVICE NATIONAL. Jan. 20, 1965 [Jan. 22, 1964], No. 2529/65. Heading F4P. The central portion of a heat insulated impervious roof 22, Fig. 2 (not shown), covering a ground storage reservoir 10 holding liquid methane floats on the surface of the liquid and is connected to the rim 18 of the reservoir by a flexible sealing joint 26. The central roof portion is formed of aluminium plates 33, 34 faced inwardly with textile fabric, outwardly with plastic sheeting and separated by concentric metal tubes 38 and by perlite. The joint 26 comprises panels 46, 48, Fig. 3 (not shown) of metal foil lined with textile and plastic material and are spaced by concentric tubes 44 similar to tubes 38 and by perlite. The peripheral panels of the joint are juxtaposed to form a skirt 50 which dips into an icefilled gutter 52 protected from ambient heat by insulation 56. The external side wall 16 of the reservoir is coated with fibre glass 20. In a modification the central portion of the roof is provided with concentric corrugations and the joint is sealingly covered by a flexible sheet through which compressed nitrogen is passed.
