  • Publication number: 20050130873
    Abstract: Improved hard surface cleaning compositions having an acidic pH provide good removal of soap scum stains. Compositions of the present invention comprise an acidic constituent which comprises either citric acid alone or citric acid in combination with an acid selected from the group consisting of sorbic acid, acetic acid, boric acid, formic acid, maleic acid, adipic acid, lactic acid, malic acid, malonic acid, glycolic acid, and mixtures thereof; at least one anionic surfactant; at least one thickener; at least one scrubbing agent; one or more optional constituents; and the balance water; wherein the aqueous hard surface cleaning composition exhibits a pH of 6.0 or less.

  • Patent number: 6402006
    Abstract: A dual mode stapling system with a first mode for plurally stapling a set of sheets parallel to one edge and a second mode for corner stapling at an angle to a set of sheets, with a single stapler mounted for linear movement by a simple linear repositioning system to selected stapling positions, but selectively further movable by the same linear repositioning system into a transition area where the stapler is automatically pivoted into the second stapling mode for corner stapling by a camming member which engages and pivots the stapler. A spring automatically reverse pivots the stapler back to the first stapling mode position when the linear repositioning system is reversed. The linear repositioning system may be a single reversable stepper motor driven leadscrew.

  • Patent number: 5039295
    Abstract: An apparatus for forming viscous flowable material, such as meat and food, into specific shapes such as meatballs and cylindrical fillings for egg rolls. The apparatus includes a container having side walls and a curved pressure plate positioned between the side walls. A rotor is located between the side walls and it has a rim facing the curved, adjustable pressure plate so that the rim and the pressure plate converge in the direction of rotation of the rotor to define a flow channel of decreasing volume for the viscous flowable material. A motor is provided to rotate the rotor in the direction of convergence with the adjustable pressure plate. Scrapers are carried by the rotor to force the viscous material flow into the channel toward the convergence of the rotor and the pressure plate to compress the viscous flowable material. A mold cavity is provided located relative to the rotor rim and the pressure plate to receive the viscous flowable material from the flow channel.
