These locking grooves are spaced at predetermined intervals circumferentially of the fixture body. An engaging projection engageable with one of the locking grooves to restrain the threaded ring from loosening is provided at the threaded ring such that it can be changed in position between engaged and disengaged positions with one of the locking grooves.

Abstract: A line attachment device for fixing objects to a line such as a fishing line, a string or a piece of rope. The device includes a shank or stem securable to the object to be fixed. The line attaching portion of the device includes a plug fixed to the stem, a cleat next to the plug and extended outward from it, and a cap with a central opening that fits snuggly over the plug. To fix the line to the device, an open loop is formed in the line and is trained through the opening in the cap when the cap is removed from the plug. The loop is drawn over the end of the plug and over the cleat such that it bears against the cleat when pulling toward the plug. The cap is then secured on the plug to hold the loop in place. The loop is secured on the cleat and is prevented by the cap from passing over the cleat whereby the line is secured to the line ataching device and thus to the object.

Abstract: A solder leveller comprises a solder bath into which a printed circuit board can be dipped to be preliminarily tinned. A pair of upright laterally acting jaws are adapted along an extended part of their length to hold the board at its opposite side edges and operate to insert in and withdraw the board from the bath. An air knife removes excess solder. The jaws are guided centrally of the bath by engagement of the side faces with the air knife nozzles which act as fixed guides.
