  • Publication number: 20200217313
    Abstract: A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.

  • Publication number: 20040071537
    Abstract: Rear loading, rear-discharging refuse truck bodies are disclosed which also serve as sealed, stackable, transportable containers. The truck bodies of the invention include a loading or charging hopper mounted in a vertically opening tailgate which closes a storage receptacle. The loading hopper is mounted so that it can be deployed during collection efforts and retracted when not in use to enable the body to be transformed into or assume the shape of a modular container box that is removable from the truck chassis much as a maritime shipping container. The truck bodies in this modular container box configuration are capable of self sealing and are transportable and stackable as interchangeable modular units separate from the truck chassis. The truck bodies of the invention include hydraulic cylinders connected to raise the tailgate and a conventional ejector panel to discharge the packed contents with the tailgate raised.

  • Patent number: 4646273
    Abstract: A method and system for well logging provide indications of the characteristics of fluid flow behind pipe. An acoustic listening device is positioned within a pipe in proximity to suspected fluid flow behind the pipe. Acoustic energy resulting from the fluid flow is detected and separated into at least two frequency groups or ranges; the first comprising acoustic energy of relatively low frequency and the second comprising acoustic energy of relatively higher frequency. The relative distribution of acoustic energy between the two frequency groups provides an indicator of the nature of the fluid flow behind the pipe.
