摘要： A method for manufacturing large diameter tapered roller bearing cages (10B). A straight metal strip, coil or plate of cage blank material (10), precisely dimensioned in width, length and thickness, with or without windows or pockets pre-cut, is fed into a rolling mill (100). The rolling mill incorporates a pair of unparallel forming rolls (102A, 102B) disposed such that the gap (G) there between forms a wedge shape. As the cage blank material (10) is fed through the wedge-shaped forming roll gap (G), one lateral side of the cage blank material is plastically deformed to reduce its thickness (T) and to elongate its length, while no deformation or only a very slight deformation is introduced to the other lateral side of the cage blank, thus forming the cage blank into an arc shape. A third roll (104) disposed in exit side of the forming rolls (102), in a pre-calculated position, bends the rolled cage blank into a circular conical ring (10A). After the entire cage blank is rolled into the conical ring configuration, the conical ring may pass through the rolling mill (100) again for a final resizing. Adjacent butt ends (12A, 12B) of the formed conical ring cage blank (10A) are aligned and joined together during the assembly process to form the large diameter tapered roller bearing cage (10B).

The body has a first portion defining a radial inner surface (98) and a radial outer surface, and a second portion defining an axially- facing base surface (110) and a radially-facing end surface (118). The annular race member has a radial outer face (58) and a radial inner face, and a first axial end face and a second axial end face (70) that both extend between the radial outer face and the radial inner face. The annular backing member is in press-fit engagement with the annular race member such that the radial outer face of the annular race member engages the radial inner surface of the annular backing member and the second axial end face of the annular race member engages the axially-facing base surface of the annular backing member such that the members are unitized.

摘要： This invention provides a convenient method for converting imines and other electrophiles into heterocyclic ring systems. The process does not require the use of metallic reagents, and is catalyzed by an organic heterocyclic carbene catalyst. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. Chiral heterocyclic carbene catalysts of the invention and methods of using these catalysts produce chiral heterocycles in high enantiomeric and diastereomeric excess.

摘要： A system includes a power amplifier, a preamplifier, a first temperature sensor, and a bias generator. The power amplifier has a first gain, which is a function of a temperature of the power amplifier. The preamplifier has a second gain, amplifies an input signal, and outputs an amplified signal to the power amplifier. The first temperature sensor senses the temperature and generates a first signal. The bias generator generates a first biasing signal to bias the power amplifier, generates a second biasing signal to bias the preamplifier, and adjusts the second gain by adjusting the second biasing signal based on the first signal. The adjusted second gain compensates a change in the first gain due to the change in the temperature.

摘要： Method and apparatus for separating components of a slurry comprising solid particles and liquid components, particularly where the slurry is under pressure. The components are separated in a hydrocyclone such that a solids-enriched slurry exits the separator via an underflow outlet while a solids-depleted slurry exits the separator through an overflow outlet and passes into a products vessel. Fluid communication is provided between the products vessel and the underflow outlet so that gas can circulate through the hydrocyclone. This gas circulation pathway may be achieved by enclosing the separation system in a housing or providing a gas circulation conduit between the products vessel and the underflow outlet of the separator or an optional solids vessel connected to the underflow outlet. Pressure within the separator apparatus may be adjusted and controlled at a negative, neutral or positive pressure while operating the hydrocyclone in balanced mode to achieve efficient separation. Where the slurry is derived from a high pressure and/or high temperature reactor and the solid components of the slurry include catalyst particles that are to be reclaimed and recycled to the reactor, the separator apparatus is preferably operated at substantially the same pressure that is found in the reactor.
摘要翻译：用于分离包含固体颗粒和液体组分的浆料的组分的方法和装置，特别是在浆料处于压力下的情况。组分以水力旋流器分离，使得富含固体的浆料通过下溢出口离开分离器，而固体贫化的浆料通过溢流出口离开分离器并进入产品容器。在产品容器和底流出口之间提供流体连通，使得气体可以循环通过水力旋流器。该气体循环路径可以通过将分离系统封闭在壳体中或在产物容器和分离器的下溢出口之间提供气体循环管道或连接到下溢出口的可选固体容器来实现。分离器装置内的压力可以调节并控制在负的，中性的或正的压力，同时在平衡模式下操作水力旋流器以实现有效的分离。当浆料来自高压和/或高温反应器并且浆料的固体组分包括待回收并再循环到反应器中的催化剂颗粒时，分离器装置优选以基本上相同的压力操作在反应堆。
