Title: Rod guide with wear gauge
Inventor: BERTAGNOLLI JOHN T
IPC: E21B17/00
Filed: 1995-01-11
Granted: 2001-12-25
Abstract: A rod guide in the form of a substantially star-shaped body molded in intimate contact with a sucker rod includes a plurality of blades, vanes, or fins projecting from the body to define a smoothly continuous concave surface of the body. At least one of the vanes has formed therein an indentation that provides a gauge of rod guide wear. The ends of the blades form knife blades to reduce resistance to fluid flow about and through the rod guide and to reduce turbulent flow behind each blade. The disclosed structure offers increased strength against bending moment subjected to the rod guide, thereby increasing resistance to bending fracture and tensile elongation. This structure also increases erodable volume of rod guide material while maintaining flow about and through the rod guide. The wear gauge of the present invention may also be included on solid, cylindrical rod guides.

Abstract: In a campground fireplace, it is common to have a wood-burning device permanently set high on a post, which affords a poor means of warmth and cooking. In this invention, a portable tub fitted with handles presents a more practical and efficient means of generating heat. Perforations along the circumference of the tub provide combustion air by natural draft. A center column may provide a medium for leaning the firewood upright onto it, and can be used to rest the tub at an elevated level by sliding it vertically over a sunken post. An annulus may be fastened to the tub from which a chain may be secured to a tree, a sunken pin, or a post. A removable cooking grille may be placed on the top of the tub. Finally, this device may be fitted with an internal bladder to contain and transport ashes to a disposal site.

Abstract: The present invention has an object of realizing highly reliable search with high precision by obtaining a clear view image over a wide view.  In particular, a reflection mirror is formed so as to correspond to an image pick-up element at a focus surface of a converging lens of an image pick-up camera and the image pick-up camera is arranged to be capable of freely performing scanning by a scanning mechanism portion.  As a result, with the image pick-up camera kept performing linear scanning, the reflection mirror performs triangular scanning in a direction opposite to the scanning direction of the image pick-up camera for every frame cycle T and a light wave taken in by the converging lens is introduced to the image pick-up element for every one frame, thereby to obtain a static view image.  The desired object is thus achieved.
