Patent number: 4488729Abstract: The invention comprises a novel method for lubricating and cooling mechanical seals, particularly those seals used in a vertical drill box system. Specifically, the invention utilizes the driving force of the rotating gears in the gear box to convey fluid to an otherwise inaccessible upper seal face. Cooling and lubricating the seal in this manner insures that the various rubber portions of the seal are not degraded by excessive heat. The invention can be utilized in any application requiring sealing of gearing mechanisms from environments containing large amounts of dust or other debris. A preferred application is in mining equipment.Type: GrantFiled: September 8, 1983Date of Patent: December 18, 1984Assignee: Step DesignInventors: Thomas A. Story, Edward P. Peglow

Patent number: 4482133Abstract: A pneumatic winch apparatus applies a constant and non-jerking pull to a cable. The amount of pull or load applied to the cable is determined by the air pressure supplied to an air motor and the radius of a drive wheel connected thereto. A maximum cable-pull load can thus be applied with an automatic non-mechanical cutoff so that a load sensitive cable, such as a fiber optics cable, is not damaged during installation thereof. Moreover, the maximum load is maintained once it has been reached.Type: GrantFiled: April 20, 1983Date of Patent: November 13, 1984Inventor: Carl D. Bishop

Patent number: 4392127Abstract: A grain moisture testing apparatus which can be used for testing of moisture content of other organic materials includes means to hold and crush the material against conductance measuring electrodes. These electrodes form one element of a voltage divider, the other element of which is formed by a resistor which is selectively adjustable among several distinct values. The resistance between the two electrodes, and thus the moisture content of the material proportional thereto, is determined by applying a constant voltage across the divider and sensing the voltage occuring across the electrodes. The voltage sensor is designed as a threshold switch which gives a simple Pass/Fail indication of acceptable moisture level. The apparatus also includes voltage supply testing means and circuit temperature testing and compensation means to assure the validity of the test.Type: GrantFiled: December 10, 1980Date of Patent: July 5, 1983Inventor: Derek E. Steele

Patent number: 4387701Abstract: A fluid friction furnace is provided having a water jacket surrounding an enclosure partially filled with a heat transfer fluid. A plurality of rotating discs sandwiched between a plurality of stationary plates are rotated inducing the heat transfer oil into grooves in the surface of the rotating discs and circulating the oil between the rotating discs and stationary plates. Continuing pressure is applied between the rotating discs and stationary plates to generate calibrated fluid pressures in the circulation of the heated transfer fluid. By virtue of this forced friction circulation, the heat transfer fluid heats the enclosure and the water jacket surrounding the same. Circulation of the water in the water jacket throughout conventional systems provides distribution of the heat.Type: GrantFiled: February 11, 1980Date of Patent: June 14, 1983Inventor: Edwin E. Gibbons
