Abstract: A crank and linkage assembly for a component of a turbocharger includes a linkage having an end defining a through bore, an inner surface of the through bore defining a linkage groove therein. The crank has a pin whose outer surface defines a pin groove. A generally polygonal retaining ring of elastically deformable wire is installed partially in the linkage groove and partially in the pin groove to retain the linkage on the pin while allowing the linkage to rotate about the pin axis. Vertices of the retaining ring are in the linkage groove, while sides of the retaining ring are in the pin groove. Once the retaining ring is pre-installed in the linkage groove, the assembly can be assembled by a push-to-connect process.

Abstract: Embodiments described herein provide dynamic blocking, a decoding algorithm which enables large-scale pretrained language models to generate high-quality paraphrases in an un-supervised setting. Specifically, in order to obtain an alternative surface form, when the language model emits a token that is present in the source sequence, the language model is prevented from generating the next token that is the same as the subsequent source token in the source sequence at the next time step. In this way, the language model is forced to generate a paraphrased sequence of the input source sequence, but with mostly different wording.
