  • Patent number: 10364402
    Abstract: The disclosed technology provides a lubricating composition comprising an oil of lubricating viscosity and 0.01 wt % to 10 wt % of an oxyalkylated aromatic polyol compound, wherein the aromatic compound has at least one alkoxy group represented by —OR1 group, R1 is hydroxyalkyl, or a (poly)ether group, and either: at least one hydroxyl group, or at least one alkoxy group represented by —OR1 group, where R1 is alkyl, or a (poly)ether group, or at least one oxyalkyl group represented by —OR1, where R1 is hydroxyalkyl or a (poly)ether group. The disclosed technology further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The disclosed technology further relates to the use of the oxyalkylated aromatic polyol compound in the lubricating composition to a passenger car internal combustion engine at least one of (i) control of fuel economy, (ii) control of corrosion, (iii) cleanliness, and (iv) control of bore wear.

  • Patent number: 10347081
    Abstract: The invention includes a system and method for conducting a focus group via networked gaming devices. A slot server or a third party server in communication with gaming devices provides access to players operating the gaming devices. A topic for the focus group's discussion is received from a marketer via a marketer terminal in communication with the slot server. The system identifies players currently operating gaming devices who also are suitable potential participants in the focus group based on a focus group pool definition received from the marketer. Those players that accept an invitation to participate, become participants. The topic is communicated to the participants and the participants comments are relayed back to a moderator who controls the focus group discussion via a moderator terminal (and a graphical user interface) also in communication with the slot server.

  • Patent number: 6627816
    Abstract: A device is provided for preventing accidental operation of a switch including a body having a surface with an opening and a cavity extending from the opening at an angle for receiving and releasably engaging the actuator member of a switch. With the switch in the desired on or off position, its actuator member is mounted into the cavity to engage the device, via the opening, such that the surface of the body lies adjacent the switch plate. Operation of the switch is prevented by the surface of the body providing a stop against the switch plate without physically anchoring the device to the switch plate.

  • Patent number: 6470662
    Abstract: A blade cutting apparatus for a rotary lawn mower. The blade cutting apparatus is defined by a plurality of blades projecting radially outward from a central hub. Each blade is defined by a first portion and a second portion, the first portion being defined by a first edge and a second edge and the second portion being defined by a third edge and a fourth edge. The first and third edges are each sharpened for enabling each blade to cut grass in two separate locations along the length of each strand of grass. Each blade is further defined by an elongated slot formed therein between the first portion and the second portion for allowing cut grass and debris to pass through each blade.
