The flea removal device comprises a housing having a top surface, a bottom surface, a first side surface, a second side surface, a front end, and a rear end. A vacuum mechanism creating a vacuum at the front end of the housing. A sprayer mechanism sprays a flea eradicating liquid. A grooming comb is releasably securable to the front end of the housing. A power mechanism powers the vacuum mechanism and the sprayer mechanism. A toggle switch alternatingly switches power between a vacuum mode and a sprayer mode. Upon activation of the vacuum mechanism, the undesirable material enters the housing through the front end of the housing. Upon activation of the sprayer mechanism, the flea eradicating liquid exits the housing through the front end of the housing.

  • Publication number: 20050045568
    Abstract: A high debris content strainer that utilizes a cylindrically-shaped screen having four removal assemblies positioned evenly around the screen periphery. Each removal assembly includes a backwash spray bar on the downstream side of the screen and a scraper/brush and discharge tube on the upstream side of the screen where the debris lodges during filtering. The screen is rotatably-mounted inside a strainer housing. A shroud surrounds ¾ of the screen periphery and includes an opening directly adjacent an input fluid flow line, as well as scoops on opposing sides of the shroud. The shroud evenly distributes the contaminated fluid flow around the screen. When cleaning the screen is desired, the screen is rotated while the backwash spray bars are activated and, in combination with the scraper/brushes, the debris is dislodged from the upstream surface of the screen and directed into the discharge tubes which divert the contaminants to a discharge pipe.

  • Patent number: 4841359
    Abstract: A photographic system where a still camera (21) and a video camera (20) are employed to view and photograph an object. The video camera (20) is employed to capture images of an object and each image is combined with a unique code. The still camera (21) produces latent images correspondingly coded and the video images may be printed or displayed on an image printer (23) to enable a selection of desired prints to be made without the need to process the film of the still camera (21) to provide proofs.
