Title: Free spinning laminated nut with automatic lock
Inventor: REYNOLDS RICHARD L
IPC: F16B37/12
Filed: 1981-09-15
Granted: 1989-03-21
Abstract: The invention provides a caged nut comprised of stacked conical spring segments that automatically and positively self-locks when tightened to a selected pre-loading, without adjustment. The nut is free running until seated, and the automatic lock mechanism ratchets freely with respect to the cage while the nut is being run down to its sealed position. Reverse rotation of the cage is prevented, however. A ratcheting element in the automatic lock mechanism allows the nut to be tightened by free rotation in the "on" direction but the ratchet prevents rotation in the "off" direction. At whatever value of preload desired, the nut is tightened to the extent necessary to provide that pre-load and the automatic lock mechanism will lock it positively in that position. The invention also includes a caged nut having stacked conical spring washer segments in which the segments are so formed as to provide a more uniform thread loading, over the entire length of the threaded portion of the segments. The invention further includes a caged free-spinning nut characterized by a prevailing tongue resisting counter-rotation having at least two washer segments in which one of the segments is formed of a material which takes a permanent set upon loading and the other segment is formed of a material that returns substantially to its original form following release of the loading force.

Abstract: A B S T R A C T         A known type of overflow structure for a sink requires two separate pieces for making a connection to the sink wall in-cluding an elbow and an open ended cap (nut).  The elbow has a female thread and the cap, which has a male thread, is screwed into the elbow from the inside of the sink to secure the elbow to the outside of the sink, the cap pressing a resilient washer, e.g. rubber or plastic, against the wall of the sink.  The present invention provides a simple one piece structure which can be installed in the overflow opening from the inside of the sink.          The sink is provided with a hole having a number of outwardly extending notches and the elbow has a like number of lugs spaced apart from a flange at the inner end of the elbow.  The outer end of the elbow is inserted through the overflow opening in the sink and orientated so that the lugs pass through the notches.  The elbow is then simply turned so that the lugs engage the back of the sink wall and compress a washer between the flange and the inner surface of the sink wall.  Thereafter, one end of a flexible hose can be force fitted over the end of the elbow and the other end force fitted over a fitting communicating with the drain tube depending from the drain opening in the sink.  The ends of the flexible hose axe clamped, if necessary.

Abstract: CONCRETE SCREW ANCHOR               ABSTRACT OF THE DISCLOSURE     Disclosed is a screw-type anchor for retention in a bore of predetermined diameter formed in a masonry type support surface.  The anchor includes an axially extending shank with an enlarged head portion at one extremity and a bore entering portion at the opposite extremity. The head portion includes rotation inducing surfaces, and a spaced, heli-cal, continuous thread having a predetermined number of threads per inch and predetermined crest diameter formed on the shank and extending from the entering portion towards the enlarged head portion for a substantial portion of the length of the shank.  The helical thread has a V-shaped cross-sectional configuration with the flanks of the thread intersecting at an included angle in the range of approxi-mately 50°-65°.  The helical thread extends about the shank at a lead angle in the range of approximately 6° to 8-1/2°, wherein the anchor can be threadingly inserted in the bore by cutting mating threads in the wall of the bore at an acceptable insertion torque level while optimizing the pull-out strength of the anchor in the support surface.

Abstract: FREIGHT CONTAINER            Abstract of the Disclosure In a freight container the tank is joined via saddle means to end frames which are provided with the standardized corner fittings which are normally used in container design and determine the outer dimensions of the container. Each saddle means in its simplest form consists of a cylindrical end ring welded to the relatively less curved spherical main portion of the tank bottom surrounded by the highly curved knuckle zone, and of a saddle ring of L-shaped cross-section having its radially extending flange secured to the end frame and/or diagonal struts thereof and its second flange extending in tank axial direction welded to the end ring. This structure permits a strong connection between the tank and the end frame, while the loads transmitted by the tank are almost completely directly introduced into the corner areas of the end frame. At the same time it permits the "breathing motions" occurring on account of temperature and pressure variations in the knuckle zone of the tank bottom. The relatively large angle at which the end ring joins the tank bottom avoids recesses which would not be readily ac-cessible and therefore be susceptible to corrosion.

Abstract: ABSTRACT  Figure 1 This invention relates to apparatus for minimising the amount of fluid leaked from a component  in a hydraulic power system when the component has failed.       The apparatus comprises a tank 1  for use as a reservoir for the hydraulic fluid,  the tank 1 having a first chamber 2 for storing a main volume of the fluid and a second chamber 3 communicating with the first chamber 2 for storing a reference volume of the fluid.  The second chamber 3 is provided with a fluid level switch 23 which deactiates the system power source when the quantity of fluid in the second chamber 3 has fallen to or below a preset level as a result of its leakage from the system via a burst hose or the like.   The chambers 2 and 3 are dimensioned so that for a given quantity of fluid entering or leaving the tank 1,  fluid level fluctuation in the second chamber 3 is greater than the corresponding fluid level fluotuation which would occur in the first chamber 1 if the fluid were only entering or leaving the first chamber 2.
