  • Patent number: 12576800
    Abstract: A cable assembly for a work machine, includes a cable and a collet. The cable includes an electrically conductive core, an insulating layer covering the core; an electrically conductive shield layer covering the insulating layer over a first length of the cable, and the insulating layer is exposed over a second length of the cable. The shield layer is folded back over a fold length, and the fold length includes two layers of the shield layer. The collet includes an inner sleeve and an outer sleeve extending over a portion of the inner sleeve at an end of the collet. The two shield layers of the fold length are arranged over the inner sleeve and under the outer sleeve, the insulating layer is arranged under the inner sleeve, and the second length of the cable extends through the inner sleeve.

  • Patent number: 8061427
    Abstract: A process for fracturing a selected region of a formation including: introducing a supply of fracturing fluid to the region of the formation until a first threshold is reached, adjusting the flow of the fracturing fluid to the region of the formation to reach a second threshold, adjusting the flow of the fracturing fluid to the region of the formation to reach a third threshold and ceasing flow of the fracturing fluid to region of the formation, the fracturing fluid being a non-participating gas and including a proppant in at least one of the stages of flow of the fracturing fluid.

  • Patent number: 7935032
    Abstract: An exercise system for simulating the motions involved in boarding sports such as surfing or snowboarding in a repetitive manner which allows for a cardiovascular, aerobic exercise that builds and tones the same muscles and reflexes used in boarding sports. The exercise system generally includes a frame including a first track and a second track. The first track is positioned parallel with the second track. A carriage assembly is slidably mounted on the first track and the second track such that the carriage assembly may freely slide back and forth along the tracks. The carriage assembly is adapted to tilt about a horizontal axis of rotation and swivel about a vertical axis of rotation. By sliding the carriage assembly along the tracks and utilizing the swiveling and tilting motions, the operator may simulate the motions and exercises encountered while enjoying boarding sports such as wakeboarding, snowboarding, surfing and skateboarding.

  • Patent number: 7559373
    Abstract: A well may intersect a mineral bearing stratum. A fracturing fluid in the nature of a non-participating gas may be injected into the stratum at high rates of flow, to yield a high down hole pressure, and a time v. pressure pulse extending over a period of time. A second pulse may follow the first pulse in relatively quick succession. There may be pauses, or period of relative relaxation between the pulses.

  • Patent number: 6407667
    Abstract: An alarm system is provided for alerting a golfer about a forgotten club. A divot tool incorporates a radio transmitter powered by a rechargeable power source for transmitting a coded transmission. A radio receiver tuned to receive the coded transmission includes logic circuitry that generates an alarm signal whenever power associated with the coded transmission drops below a threshold level. One or more alarm devices are coupled to the logic circuitry to generate alarm(s) when the alarm signal is supplied thereto. A power source is coupled to the radio receiver for supplying power thereto and for supplying a charging current for the rechargeable power source via an electrical coupling. When a golfer places a club or other accessory on the ground, the divot tool is placed near the club. As long as the golfer remains within a prescribed range, no alarm will be activated. However, if the golfer moves further from the divot tool than the prescribed range, an alarm is produced.
