Abstract: The instant invention relates to a double-coated sintered composition on a hard-faced disk blade for agricultural use as a rotary knife blade of a farm implement termed a harrow wherein the sintered hard-faced composition is applied to both the concave and convex sides of the rotary harrow disk blade to provide protection against soil abrasion and wear.

Abstract: A drain pump assembly is provided for use with an evaporative cooler having a water reservoir and a circulating pump. The drain pump assembly includes a drain pump operative to pump accumulated water from the reservoir when the drain pump is turned on and a controller. The controller is operative to turn on the drain pump automatically after the circulating pump has operated for a predetermined circulate time period and also is operative to turn on the drain pump in response to actuation of a manual drain actuator. The controller turns on the drain pump for a drain time that is equal to or greater than a predetermined drain period. The controller can terminate operation of the drain pump and reset the drain time is power to the circulating pump is interrupted during operation of the circulating pump. The controller includes a processor and a data storage device operative to store data representing the accumulated circulate time when power to the circulating pump is interrupted.

Abstract: The invention is directed to a latching arm for an electrical connector. The latching arm has a main body with a connection point to the housing of the electrical connector. The main body has a securing section for engaging a mating connector. The main body has a back-up member for engaging the housing. Whereby when the connection point weakens due to stresses on the connection point, the back-up member engages the housing thereby maintaining a good connection between the electrical connector and the mating connector.

Abstract: Portable car hoist convertible to a trailer which has wheels for towing a vehicle. The hoist includes a trailer with a suspension, a wheel assembly, a base frame assembly, a liftable platform assembly, and a lift apparatus. A foldable ramp, a platform, and extension channels support a vehicle to be lifted, and a chock assembly retains the vehicle on the platform. A safety latch prevents accidental lowering of the platform assembly.
