Patent number: 7143867Abstract: An oil level monitoring and replenishment system for use with an internal combustion engine having an oil sump. The system as a sensor which continuously measures the sump level in the reservoir for holding a quantity of oil to be used in replenishment of the sump. A sensor monitors the oil level in the sump and causes replenishment from the reservoir when needed. The reservoir has warning circuit interactive with a reservoir sensor to signal from the reservoir has reached a lower level of oil and requires the filling. The sensor also provides means to signal when the reservoir has been filled to the desired level to prevent overfilling.Type: GrantFiled: November 24, 2003Date of Patent: December 5, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Kewal K. Chopra

Patent number: 6364719Abstract: The present invention is an improved linear action battery clamp usefull for attaching a battery cable to a vehicle's battery terminal. The clamp has a frame member with a fixed jaw and a fixed handle. An actuator rod is mounted in the frame the rod being mounted within first and second bores. The rod has a second jaw mounted on one end moveable towards the fixed jaw of the frame to clamp a battery terminal. A sliding actuator is mounted on the rod being adapted to move the rod linearly the actuator being juxtaposed an actuating arm attached to the frame, the arm having a pair of cam surfaces on one end juxtaposed the actuator for moving the actuator. A brake member acts on the rod the brake normally restricting the rods' linear motion serving to hold the rod in a fixed position. The brake has a release position that allows the rod to be moved in the opposite direction by hand so as to open or disengage the jaw.Type: GrantFiled: March 30, 2001Date of Patent: April 2, 2002Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Kewal K.

Patent number: 5832796Abstract: An attachment for installing a solderless connector to wire ends to form an electrical connection using with a rotary hand held tool is described. The attachment has a spindle member held by the tool. The spindle has a cylindrical member attached to the spindle having a frustoconical opening sized to accept and surround a portion of a solderless connector. The frustoconical opening has a plurality of detents which hold the solderless connector firmly and apply sufficient torque to the solderless connector to twist the wires inserted into the solderless connector together when the solderless connector is rotated by the tool. The detents will release their grasp on the solderless connector when sufficient twisting has been applied to the wires to electrically connect the individual wires but prior to the point at which the wires are twisted beyond their elastic limit.Type: GrantFiled: March 7, 1997Date of Patent: November 10, 1998Inventor: Kewal K.
