Abstract:

A yarn tangler arrangement for all types of filament yarns which includes two individual members which are adapted to be threadably coupled together. Each of the members include a longitudinally extending bore which terminates in respective chamfered portions which define a yarn processing chamber. An air supply bore is arranged in one of the members at a predetermined angle with respect to a terminal edge of one of the chamfered portions with the supply bore feeding compressed air into the chamber so as to aspirate yarn from one longitudinal bore accommodating the yarn to be processed with the processed yarn then being directed from the chamber to the other longitudinally extending bore which accommodates the processed yarn.

Abstract:

This disclosure depicts a novel multiple position electric pushbutton switch. The novel switch comprises a cam and a movable contact assembly having at least two spring elements, each having an electrical contact and a cam-engaging portion. The switch further comprises at least two stationary electrical contacts for contacting the electrical contacts of the movable contact assembly. A housing is provided for containing the cam, the movable contact assembly and the stationary contacts. As the cam is depressed and moved downward into the housing, the cam engages one of the spring elements of the movable contact assembly causing the electrical contact on the spring element to contact a corresponding stationary electrical contact. As the cam is depressed further into the housing, the cam engages a second spring element causing the electrical contact on the second spring element to contact a corresponding stationary contact thereby resulting in a sequential connection of the electrical contacts as the cam is depressed into the housing.
