摘要： The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member connected to a toothbrush head member. The head is divided into two regions. A "toe" region is defined as the part of the head which is furthest from the handle and a "heel" region is the portion of the head which is closest to the handle. A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end. Likewise, a multiplicity of bristles extend from the toe region of the head, wherein said bristles extending from the toe portion of the head are at least as tall as the general height of said bristles extending from the heel portion when viewed from the side and wherein the side profile view of the distal ends of the bristles extending from the toe portion form a generally linear surface which forms an angle relative to the general plane of the bristles extending from the heel portion of from 0.degree. to about 45.degree. declining from the edge of the toe portion distal to the heel portion to the edge of the toe portion which is proximal to the heel portion.

摘要： Dense, strong, composite materials are produced from mixtures of silicon and silicon carbide. The composite materials are characterized by a mixture of finely-divided silicon carbide in a substantially continuous matrix of silicon. The composite materials contain from about 40 to about 60 percent by volume silicon carbide and from about 60 to about 40 percent by volume silicon. The composite materials are produced by initially producing a finely-divided silicon carbide starting component and forming the component into a green body of the desired shape. The green body is subsequently impregnated with molten silicon in the absence of any substantial amount of carbon. Suitably, a thermoplastic resin binder may be added to the silicon carbide starting material to aid in forming the green body. The impregnation step may be carried out by surrounding the green body with finely-divided silicon metal and heating the covered body to a temperature above the melting point of silicon. The composite materials described have flexural strength of over about 90,000 psi at 1100.degree. C., elastic modulus of about 38 million psi at room temperature, are essentially non-porus and have densities ranging from about 2.6 to about 2.8 g/cc.
摘要翻译：由硅和碳化硅的混合物制成密集的，强的复合材料。复合材料的特征在于基本上连续的硅基体中的细碎碳化硅的混合物。复合材料含有约40至约60体积％的碳化硅和约60至约40体积％的硅。复合材料通过最初生产细碎的碳化硅起始组分并将组分形成所需形状的生坯体来制备。随后在不存在任何大量碳的情况下，将生坯体浸入熔融硅中。适当地，可以将热塑性树脂粘合剂添加到碳化硅原料以帮助形成生坯。浸渍步骤可以通过用细碎的硅金属包围生坯并将被覆盖体加热到高于硅熔点的温度来进行。所描述的复合材料在1100℃下具有超过约90,000psi的弯曲强度，在室温下的弹性模量约为3800万psi，基本上为非孔隙，密度范围为约2.6至约2.8g / cc。

摘要： A valve for the expiratory tubing of a ventilator circuit. The valve assembly includes a valve body, diaphragm, top cap and control tubing. The valve body includes a valve seat, annular surface, sealing ribs, along with other annular members. The diaphragm includes a thick center portion, connected by a thin web to a relatively thick annular rim and surrounding flange. The top cap includes a compression ring which clamps the diaphragm annular flange to the valve annular surface. In the valve open position, the valve body supports the diaphragm only at the diaphragm flange.

摘要： A system is described for the collection and re-infusion of fluids from a patient. The system includes a non-disposable rigid cannister and a disposable flexible liner that is placed in the cannister. Fluids are collected from a patient in the cannister liner. The liner is then removed from the cannister and the contents are re-infused back into a patient. The system is unique in that it provides a stand along vacuum means for continuously providing a relatively high vacuum to the cannister and a relatively low vacuum inside the liner to cause the liner to expand against the walls of the cannister. The stand alone vacuum means also provides a consistent relatively low vacuum to a patient's cavity for collecting fluids from the patient without damaging the patient's internal organs.
摘要翻译：描述了用于从患者收集和重新输注流体的系统。该系统包括非一次性刚性罐和放置在罐中的一次性柔性衬里。从罐筒内的患者收集流体。然后从罐中取出衬里，将内容物重新注入患者体内。该系统是独特的，因为它提供了一种沿着真空装置的支架，用于连续地向罐提供相对较高的真空度，并且在衬套内部具有相对较低的真空度，以使衬套相对于罐的壁膨胀。独立的真空装置还为患者的腔提供一致的相对低的真空，用于从患者收集流体而不损坏患者的内部器官。
