摘要:
Various embodiments are disclosed of dampening apparatus for a pressure gauge in which a short length of sleeve, ferrule, hub or thimble encircles a pointer shaft in a close but loose fit relation defining a clearances packed with a high viscosity dampening agent such that it serves to decelerate and cushion any sudden shock or pulsation force that would otherwise be transmitted from the pointer shaft to a pointer registering values of pressure of fluid pressure being monitored.

A dampening apparatus for a pressure gauge in which a housing secured to the amplifier of the pressure gauge encircles the pointer shaft in a close but loose fit relation so as to define a controlled clearance packed with a high viscosity dampening agent such that it serves to decelerate and cushion any sudden shock or pulsation force that would otherwise be transmitted from the pointer shaft to a pointer registering values of pressure of fluid pressure being monitored.
摘要:
An automatic system for providing a liquid to a rivet setting mechanism is described. The liquid lubricates, cleans, and cools the rivet setting mechanism. The system includes a reservoir for the liquid, a metering device, and controls.

A shoulder fired weapon comprising: a lower receiver, a magazine removably attachable to the lower receiver; a buffer tube attached to the lower receiver; a buttstock attached to the buffer tube, and where the buttstock can rotate with respect to the lower receiver and the buttstock can lock into place. A rotating buffer apparatus comprising: a front end buffer tube, the front end buffer configured to screw into a lower receiver of a shoulder fired weapon; a rear end buffer tube, aligned with and adjacent to the front end buffer tube; the rear end buffer tube configured to attach to a buttstock; and where when the rotating buffer apparatus is installed into the shoulder fired weapon, the buttstock can rotate with respect to the lower receiver and the buttstock can lock into place.
摘要:
There is disclosed a pressure gauge construction in which the dial plate includes recessed indentations interfit with pins projecting beyond the front face of the gauge movement for supporting a dial plate in place. An adhesive cement is contained between the back face of the dial plate and the front face of the movement effects an adhesive bonding therebetween.
摘要:
A system for first setting a blind rivet and then verifying the correctness of the set comprising a rivet setting tool to set the rivet and computer logic to verify the correctness of the set. The setting tool includes a jaw assembly for holding the stem of the rivet's mandrel fitted to an axially movable pulling shaft. Both the pulling force of the setting tool and the displacement of the pulling shaft are measured and the measurements are interpreted by an integrator to determine the total energy of the setting process. The determined total energy is then compared with an ideal total energy to assess whether or not the set of the particular rivet is acceptable. Other quantitative comparisons may be made against other ideal values.

There is disclosed a pressure gauge construction in which a diaphragm assembly responsive to changing values of fluid pressure being supplied to the gauge is secured against an internal support surface of the casing by a combination of sealant and thermal staking.
摘要:
The likelihood of successful transfer of a blind rivet from a loading device to the nose of a blind rivet setting tool is substantially improved by conforming the end surface of the nose which receives the blind rivet to the convex surface of the blind rivet flange which is received and by making the inner diameter of the nose bore correspond to the inner diameter of the convex rivet surface.
