Publication number: 20110239479Abstract: A tape measure includes a casing containing a conventional tape with a hook on its outer end and a return spring. A magnifying lens is mounted in a front end of the casing above the tape with an indicator line on the bottom of the lens extending transversely of the tape. An LED in one side of the casing illuminates the lens and the area therebeneath. A marker is slidable in the lens beside the tape and aligned with the indicator line. A slider, which can be operated with a thumb, turns on the LED and then pushes the marker against a workpiece. When the slider is released, a spring returns the marker to the rest or non-use position and the LED is turned off by the slider.Type: ApplicationFiled: March 31, 2010Publication date: October 6, 2011Inventors: Ronald R.

Patent number: 7814941Abstract: A fluid transfer system includes a fluid container to receive a liquid and an apparatus for pressurizing liquid in the container including a deformable envelope defining a space for receiving a gas. Deformation of the envelope contracts the space to a contracted condition such that, when the space includes the gas, deformation of the envelope contracts the space to effect a transfer of a portion of the gas to the container to effect pressurization of the liquid in the container. A dispensing nozzle includes a fluid passage having a nozzle inlet and outlet, and an orifice defined by a valve seat. The nozzle inlet is in fluid communication with the container for effecting a discharge of the liquid from the container. A sealing member is biased into sealing engagement with the valve seat for sealing fluid communication between the nozzle inlet and the nozzle outlet.Type: GrantFiled: March 19, 2003Date of Patent: October 19, 2010Assignee: Scepter CorporationInventors: Peter Alex, Johnny Laureijs, Ronald R.

Patent number: 7422039Abstract: An apparatus for transferring a fluid from a supply container to a desired receptacle. The apparatus includes a conduit having a fluid passage with a valve seat and a flexible containment member. A moveable sealing member is coupled to the flexible containment member and is configured for sealingly engaging the valve seat. An activator is coupled to the sealing member for displacing the sealing member from the valve seat to effect the creation of a reduced fluid pressure in the fluid in the supply container.Type: GrantFiled: May 24, 2004Date of Patent: September 9, 2008Assignee: Scepter CorporationInventors: Ronald R. Chisholm, Peter Alex

Patent number: 6412528Abstract: A manually operative siphoning pump apparatus for transferring liquid from one container to another container. The siphoning pump apparatus has a hollow cylindrical pump body through which liquid from one container to another can flow and a bellows attached thereto for establishing a vacuum within said pump body. The hollow pump body has a inlet pipe and an outlet an elongated flexible hose or tube connected to each of the pipes. The siphoning pump apparatus has an axially movable valve within the hollow pump body for initiating, controlling and shutting off the flow of liquid through the pump body during the siphoning process and, hence, from one container to another container. The axially movable valve has a cylindrical head at one end thereof and a connector at the opposite end thereof for fixing it to the bottom of the bellows. The axially movable valve is manually controlled by an elongated lever arm pivotally attached to a housing handle at one end and fixedly attached to the bottom of the bellows.Type: GrantFiled: September 12, 2001Date of Patent: July 2, 2002Inventors: Peter Alex, Johnny Laureijs, Ronald R.
