Abstract: Process for repulping wet strength paper containing at least one wet strength resin in which initial breakdown of the paper is conducted at a first pH and the substantial completion of the conversion to fibers is conducted at a second pH which is higher than the first pH.

Abstract: Wastepaper containing printing ink is refined in the presence of the reaction products of castor oil with an alkoxylated fatty acid, alcohol, amine, amide, phosphate ester, polyhydroxy alcohol, or sorbitan, and the detached printing ink particles are subsequently removed from the paper stock suspensions by flotation or washing.

Abstract: A child's toy vehicle having a safety device includes a vehicle having a receiver circuit which may be enabled by an electromagnetic signal emitted by a remote control, handled by an adult, and a pushbutton, in series with a motor, to be depressed by the child driving the vehicle. A switch breaks the supply to the receiver circuit thereby disabling it at the same time as it makes a bridge across the power supply and the child operated pushbutton. The invention is applicable to children's toy vehicles driven by very young children, so that an adult located remotely can break the motor supply to stop the vehicle at any given time, for safety purposes.

Abstract: This invention relates generally to insolubilizers for use with binders in paper coating compositions. There is provided a process for preparing both an insolubilizer and paper coating composition containing the insolubilizer and a binder which, when applied onto paper products, significantly enhances their wet-rub resistance.The insolubilizer is prepared by:(a) forming a glyoxal-urea adduct by reacting from about 1.0 to about 4.0 moles of glyoxal with about 1.0 mole of urea, at an elevated temperature,(b) cooling the glyoxal-urea adduct to room temperature,(c) adding from about 0.5 to about 2.0 moles of free glyoxal to the glyoxal-urea adduct to form an oligomer, and(d) adjusting the pH of the oligomer to from about 5 to about 7.

Abstract: An aqueous dye or pigment ink particularly adapted for ink jet printing containing a fluorinated block copolymer prepared from a fluorinated oxazoline or oxazine. Resulting inks exhibit high print quality over a range of papers.

Abstract: A children's bowling game having two bases (2), with a channel (13) for the bowling balls (6). Between the bases there is located a board (1) acting as a lane for the bowling pins (5). The bases each include a scoreboard (3). When the game is dismantled, said bases form a container for the remaining parts of the game, which may be carried by a handle (14).

Abstract: A child's basketball game includes a ballasted base to which there is attached a telescopic column formed by two sections, the upper one of which supports the ring carrying the net and board. The column is fixed with a trapezial support. The unit is easy to dismantle for storage in a small space. The game is for children and the height is adjustable depending on the size thereof.

Abstract: An apparatus and method is provided wherein the foam inhibiting effectiveness of defoaming and antifoaming additives on various types of foamable liquid mediums is measured. A single generally cylindrical foam cell having openings at both ends is provided wherein an interchangeable foam cell insert having varied geometry is longitudinally disposed within the foam cell. The foam cell insert is provided with a plurality of centralizer walls extending into the foam cell with an agitator member being carried by the centralizer walls. Foamable liquid medium is introduced into the foam cell and recirculated therethrough to form a dynamic fluid-flow system. As the liquid medium passes through both the foam cell and the foam cell insert, it comes into contact with the agitator member carried by the centralizer walls of the foam cell insert forming foam which accumulates in the foam cell.
