  • Publication number: 20020159831
    Abstract: A clip for aligning a top portion and bottom portion of a fabric treatment apparatus comprises a clip body having a rear engaging portion and a front engaging portion. The rear engaging portion is made to receive an associated bottom slot edge found in the bottom portion of the fabric treatment apparatus. The front engaging portion is capable of receiving, substantially simultaneously, a second bottom slot edge, which opposes a first bottom slot edge, and a top slot edge located in the top portion of the fabric treatment apparatus. The clip further comprises an alignment tab communicating with the front engaging portion in at least two locations, such that the top portion and bottom portion of the fabric treatment apparatus are operatively aligned and a side-to-side relationship between the same is maintained.

  • Patent number: 6434792
    Abstract: A new and improved hinge for use with a refrigerator door. The inventive hinge is a drawn hinge, created by the drawing process. The inventive hinge includes first and second flanges, a pin, and a pin arm. The flanges on each side allow use of a thinner piece of metal in creating a hinge, while retaining the strength of a thicker piece of metal. The pin arm is extended in order to prevent pinching when opening and closing a refrigerator door.

  • Patent number: 5260179
    Abstract: Imine dyes useful in photographic materials have the formula ##STR1## wherein D is selected from ##STR2## and wherein E.sup.1, E.sup.2, E.sup.3, and E.sup.4 each individually represents strongly electron-withdrawing groups; R.sup.1 and R.sup.6 each individually represents an alkyl group of 1 to about 8 carbon atoms, or an aralkyl or cycloalkyl group of 5 to about 10 carbon atoms, or an aryl group of 6 to about 14 carbon atoms; R.sup.2, R.sup.3, and R.sup.11 each individually represents an alkyl group of 1 to about 8 carbon atoms, or an alkenyl group of 2 to about 8 carbon atoms, or an aryl, aralkyl, or cycloalkyl group of 5 to about 14 carbon atoms; or R.sup.2 and R.sup.3 individually represent the non-metallic atoms necessary to form a 5- or 6-membered fused ring with the phenyl ring to which the nitrogen is attached, or together represent the non-metallic atoms required to form a 5- or 6-membered ring with each other; R.sup.4, R.sup.7, R.sup.8, R.sup.9, and R.sup.

  • Patent number: 4053320
    Abstract: The process for the production of a refractory body comprises comminuting plasma dissociated zircon sand, mixing the comminuted sand with a functional additive for the purpose of reducing the subsequent firing temperature, moulding the resulting mixture to form a body, and finally firing the moulded body until sintering occurs.

  • Patent number: 4047970
    Abstract: The process for producing zirconium based pigments (also known as stains) comprises the direct use of plasma disassociated zirconium sand. The sand is comminuted to a suitable particle size, mixed with a color determining agent such as ammonium metavanadate and a mineralizer such as sodium fluoride, after which the resulting mixture is calcined to bring about a reaction between the zirconium sand and the color determining agent to produce the required pigments. The resulting calcined pigment is then ground to a suitable particle size ready for application to ceramic tiles.
