Abstract: An adjustable lamp assembly comprises a PAR type lamp housing an a mounting base for supporting the housing. A mechanical adjusting assembly interconnects the housing and the mounting base for permitting selective adjustment of the housing relative to the base about first and second axes lying in respective planes located at approximately 90.degree. relative to one another. The adjusting assembly includes an intermediate support member connected between the housing and the base with first connecting assembly joining the intermediate support member to the base and a second mechanical connecting assembly joining the intermediate support member to the housing. The first and second connecting assemblies each including separate first and second spring biased circular arrays of teeth-like members selectively movable axially along the respective first and second axes between locked positions and adjustment positions wherein selective rotary adjustment about the respective axis is permitted.

Abstract: A fitting connection for joining plastic tubing to associated structure comprises a main fitting body having an axially inwardly extending cylindrical chamber with an inner end portion of a diameter d.sub.1 terminating at its innermost end in a radially inward extending wall. The outer end of the chamber opens to the exterior of the body and has an open diameter d.sub.2 which is larger than d.sub.1 with a shoulder at the juncture between the inner and outer end portions of the chamber. Plastic tubing having a circumferential corrugation adjacent an end portion thereof extends axially into the chamber with the innermost end of the tubing abutting the wall. A retaining ring acts to retain the tubing in the fitting body and includes a sleeve received in the outer portion of the chamber with the innermost end of the sleeve in engagement with the shoulder and a plurality of resilient tabs having free ends extending toward the shoulder.

Abstract: A nut having a plurality of thread convolutions is formed with a plurality of punches from a metal blank to eliminate time consuming tapping operations. To make the nut, a pair of punches are used to form recesses in opposite sides of the blank and to form projections which extend axially outwardly from the sides of the blank. The recesses are separated by a web which is shaped by another pair of punches to form an inner thread convolution. The two axially extending projections each contain a volume metal which is the same as the volume of metal contained in upper and lower thread convolutions. The upper and lower thread convolutions are formed by cold working the metal of the blank to eliminate the axial projections and form radially inwardly extending projections in the central opening in the blank.
