Abstract: Methods and systems for managing personnel security at physical locations. One such method includes managing personnel security for a plurality of different sponsor entities from an administrator entity. The method includes obtaining screening data from a plurality of different vendor entities and individuals associated with those vendor entities, where the screening data is obtained to screen the vendor entities and individuals to determine whether physical access to facilities of the sponsor entities should be granted. The method further includes performing background checks on the outside companies and their employees based on the screening data, where the background checks are initiated by the administrator entity using a computer-based system operated and maintained by the administrator entity.

Abstract: A valve for causing pulsatile flow in a multi-piston plunger pump includes a valve poppet, a valve seat, and a spring biasing the valve poppet against the valve seat; and a mechanism holding the valve poppet in an open position, thereby producing pulsatile flow from the pump. The mechanism includes a magnet and an adjustment mechanism for moving the magnet toward and away from the valve poppet. When the magnet is moved toward the valve poppet, the magnet attracts the poppet away from the valve seat, and when the magnet is moved away from the valve poppet, the magnet releases the poppet. The spring then biases the poppet against the valve seat in a closed position.

Abstract: A housing for a pressure washer for internal components of the washer such as a pump, an electric motor for the pump and a valve assembly. The housing has first and second identical interconnected housing halves. The inner surface of the housing halves include pairs of ribs interacting to engage the internal components.

Abstract: A pressure washer according to the preferred teachings of the present invention is disclosed including a pump driven by a gear reduced, high speed, series universal motor supported in a housing by a switch housing. The motor is stopped and started by a pressure actuation switch to remove the necessity of an unloader valve. A valve assembly is provided which includes provisions for allowing or for preventing weepage through the pump and for relieving excessive pressure. The housing is formed of identical, non-mirror image housing halves which are interconnected end for end. Pairs of ribs upstand from the inner surface of the housing halves, with the first of the pair of ribs of the first housing half interacting with the second of the pair of ribs of the second housing half to engage the internal components while the second of the pair of the first housing half and the first of the pair of the second housing half not interfering with the internal components.
