摘要： An inexpensive, efficient seal member having a tubular housing member that can be integral to or attached to a frame of a motor to form a ring seal around the shaft of the motor prior to mating the shaft with a pump or other driven device. The flexible elastomer washer member is located in a pocket at the end of the housing. The inner diameter of the flexible elastomer washer member is smaller than the shaft diameter. The thickness of the flexible elastomer washer member is larger than the depth of the pocket and is held in the pocket by a resilient retaining member having a plurality of tangs forming an interference fit with the walls of the housing. Next, the shaft is slidably extended through the flexible elastomer washer member forming the ring seal.

摘要： The seal or pattern between two machine parts has on one of the sealing gap-forming, facing surfaces (5) a plastic layer (1) with closely juxtaposed depressions (8) which have the form of partly cut off voids of an expanded plastic structure. They are formed by the removal of a plastic layer (3) expanded on the machine part, the layer thickness being so uniformly reduced that the voids (4) of the bottom void layer (4) adjacent to the base surface (5) of the machine part are open. This avoids the insulating action of the closed voids of an expanded plastic layer and the latter has a very limited weight, which avoids any risk of the layer being detached or separated due to centrifugal forces. Moreover, in simple manner, a honeycomb-like, open surface structure is obtained, so that there is a labyrinth effect in the sealing gap. In order to obtain minimum, sealing gaps by running in the open, honeycomb-like surface structure is particularly advantageous, because the solely linear contact which occurs ensures a rapid running in of the mating surface, which can be abrasively prepared. The seal or packing is particularly suitable for very rapidly rotating machine parts.

摘要翻译： 两个机器部件之间的密封件或图案在密封间隙形成面对面（5）中的一个上具有紧密并置的凹陷（8）的塑料层（1），其具有部分切断的膨胀塑性结构的空隙的形式 。 它们通过去除在机器部分上膨胀的塑料层（3）形成，层厚度被均匀地减小，使得邻近底部表面（5）的底部空隙层（4）的空隙（4） 机器部分打开。 这避免了膨胀塑料层的封闭空隙的绝缘作用，而后者具有非常有限的重量，这避免了由于离心力而使层分离或分离的任何风险。 此外，以简单的方式获得蜂窝状的开放表面结构，使得在密封间隙中存在迷宫效应。 为了获得最小的密封间隙，通过在开放的蜂窝状表面结构中的运行是特别有利的，因为发生的单线性接触确保配合表面的快速运行，这可以被磨蚀制备。 密封或包装特别适用于非常快速旋转的机器部件。

摘要： A composite seal ring has a porous main body and a non-porous insert molded into it. Differential rates of coolant absorption between the porous main body and non-porous insert cause the whole ring to swell into a regular pattern of distortion. In order to compensate, the seal ring, after initial machining, is pre-soaked to simulate use and deliberately cause the same kind of distortion. It is then lapped flat from its distorted state.

摘要： A flat gasket with a core and mesh-like elastomeric overlays where the overlays are screen-printed onto the core. The dimensions and shape of the mesh can be varied continuously over the surface of the core allowing the gasket to be adjusted for its intended use. Additional reinforcements may be printed onto the core and overlays at the same time the overlays are printed, reducing processing time and expense and allowing the gasket to be further adapted for its intended use.

摘要： A method of manufacturing a steel plate for a steel laminate gasket comprises applying a first seal coating consecutively on at least one side of a base plate in the shape substantially the same as that of an actual steel plate for constituting the gasket. After the first seal coating on the base plate is dried, the base plate is pressed or cut to form a plurality of steel plates. Each steel plate has a configuration as in the actual steel plate, an outer surface formed by the first seal coating on the entire one side thereof and a plurality of holes therein. When a steel laminate gasket is formed, the steel plate with the seal coating thereon is stacked with other steel plates so that the seal coating is located between the two steel plates.

摘要： A gasket formed from a perforated core sheet having a first facing layer formed from a material having a relatively high degree of thermal conductivity on one side thereof and a second facing layer formed from a relatively compressible, non-asbestos gasket material on an opposite side thereof. The facing layers are attached to the core by mechanical retaining means. The retaining means can be formed as a pair of opposed tangs on opposite sides of each perforation in the core or as a dome-shaped structure having an aperture formed in an end thereof.

摘要： Apparatus and system for making positive locking sealing rings having interengagable ring end notches with mating surfaces thereof at closely precise angles of intersection. In a preferred form, interal notch end faces, and ring terminal ends, are parallel and disposed at a slight angle to the ring axis to provide a positive angular interlock between the notches in a free hooked condition. The term "free hooked" as used herein means latched but not confined in a final assembly. The rings, including notches and ring terminal ends, are formed automatically in the apparatus of the invention by a unitized multiple component or faced cutter, such as a milling cutter. The cutting surfaces and cutter unit for the angled face notch design are advanced at an angle to the ring axis equal to the angles of the notch face surfaces. The cutter element faces are so formed, disposed, and the cutter so controlled, preferably in a so-called single plunge notch cutting operation, as to insure a preserved uniform ring material section below the notch base for ring strength.The machine used includes a ring blank loading station, two cutting stations for top and bottom hook cuts, a composite unloading-hooking station, a hooked ring catcher unit, and an index unit for transfer of parts under each station. A programmable controller function to control the operating cycle. Preferably, a circular design is used, although a linear configuration is possible.

摘要： In mechanical seals adapted to perform in high temperature environments, fragile gaskets characterized by poor elasticity and conformability are used to perfect a seal between adjacent parts. Gaskets may be made of graphite, carbon, asbestos and/or fiberglass containing material. In order to perfect such a seal, gaskets with a parallelogram cross-section are used. They are expanded radially and their cross-section changed when placed between two parts during assembly.

摘要： A method of applying a refractory coating or facing to a ferrous metal substrate that is in the form of a finished article, such as that of a piston seal or the like, and that has sections of such small dimensions as to be easily distorted by heat. The method includes an induction heating step carried out under conditions so controlled as to effect a bond of greatly improved strength in shear between the coating and substrate without, however, causing heat distortion of even the small dimensioned sections beyond functionally permissible limits. An agent capable of effecting diffusion bonding, such as free nickel, or an alloy or mixtures containing free nickel or an equivalent bonding element, is made available at the interface in the coating and substrate to facilitate the obtaining of such greatly improved bond as a result of the induction heating step. The bond obtained is in excess of 10,000 psi in shear and generally equal to or in excess of the tensile strength of the refractory coating.
