US Patent:

59340363, Aug 10, 1999

Filed:

Nov 1, 1996

Appl. No.:

8/740696

Inventors:

Daniel P. Gallagher - Niwot CO

International Classification:

E04B 532

US Classification:

52323

Abstract:

An insulated concrete slab assembly for use over expansive soils. A slab is cast in place by pouring concrete into preshaped insulating forms. The forms remain permanently in place and provide insulation to reduce heat transfer through the slab. The shape of the forms provides strengthening ribs on the slab. The ribs act as beams which allow the slab to bridge or cantilever over expansive soil between foundation walls. The forms are supported during construction by support members or legs which later prevent damage to the slab by eliminating or limiting the forces which can be applied to the slab by expanding soil.

Abstract:

A insulating foamed polymer wall panel comprising a sheet of foamed polymer having sizable dimensions to form a substantial part of a wall when assembled. Adjacent wall panels are coupled using splines which, together with the side edges of the panels, form the sidewalls of a cement channel between the panels. The panel has connecting slots for receiving the splines and a plurality of edges, each top and side edge having a longitudinally extending groove to accommodate the fill of cement therein. The grooves provide tongue-and-groove connections between the cement post and adjacent wall panels once the cement has set, thus locking the latter into place.

E21B 17/03

Abstract:

A universal joint (U-joint) assembly transmits torque from a drive component to a driven component across an articulating joint. The U-joint assembly includes male and female U-joint members, a central ball joint, and a retaining device configured to secure the assembly in an assembled configuration. The female U-joint member includes a cavity extending into a receptacle end thereof. The cavity terminates in a circular receptacle and includes a plurality of rectangular channels extending radially outward from the cavity at equal intervals, each channel defined by three planar drive surfaces. The male U-joint member has a drive end with a plurality of corresponding rectangular extensions protruding from an outer periphery of the drive end, each extension including a plurality of axial angular surfaces. When assembled, each of the angular surfaces of the drive end opposes a corresponding one of the drive surfaces of the cavity. Other embodiments are also disclosed.

F16C 33/66

Abstract:

A rotatable bearing assembly transfers a weight of a drill string to a mud motor output shaft extending therethrough. The bearing assembly includes an outer bearing housing, an upper radial bearing assembly providing an upper radial bearing between the outer bearing housing and the output shaft, a balance piston that fluidly seals an upper end of the outer bearing housing and balances a pressure within the outer bearing housing, a lower radial bearing/seal assembly configured to both fluidly seal a lower end of the outer bearing housing and provide a lower radial bearing between the outer bearing housing and the output shaft, and a thrust bearing assembly received within the sealed interior of the outer bearing housing such that the bearing assembly initially operates in a sealed, lubricated mode and then a mud lube mode in the event of one or more seal failures. Other embodiments are also disclosed.

Abstract:

A universal joint (U-joint) assembly transmits torque from a drive component to a driven component across an articulating joint. The U-joint assembly includes male and female U-joint members, a central ball joint, and a retaining device configured to secure the assembly in an assembled configuration. The female U-joint member includes a cavity extending into a receptacle end thereof. The cavity terminates in a circular receptacle and includes four flat surfaces extending longitudinally therefrom at 90-degree intervals. The male U-joint member has a drive end with four multi-angled surfaces extending longitudinally from the drive end at 90-degree intervals about a periphery of the drive end. When in an assembled configuration, each of the multi-angled surfaces of the drive end of the male U-joint member opposes a corresponding one of the four flat surfaces of cavity of the female U-joint member. Other embodiments are also disclosed.
