  • Patent number: 8431059
    Abstract: A mosaic-style art kit is provided. The art kit includes a frame, modeling material, and a guide sheet. The frame includes a peripheral surface operably configured to overlie the guide sheet, and a mosaic-style internal structure having partitions forming cavities for receiving and retaining the modeling material. A front side of the frame is placed on the guide sheet such that the mosaic-style internal structure is aligned with a design on the guide sheet. The design thereby instructs a color of modeling material to be inserted into each cavity of the internal structure. The modeling material is inserted accordingly, and the frame and guide sheet are separated to produce a mosaic-style art product.

  • Patent number: 7988123
    Abstract: A compactable mold comprises a main mold frame structure and plural wall structures including two end wall structures and two side wall structures. The plural wall structures define a mold cavity for forming a block from a mixture introduced into the mold cavity. At least two of the plural wall structures are movable wall structures for compacting the mixture. A described compactable mold has end walls and side walls that are shaped for forming tongue and groove features on a compacted block, and the end walls and side walls are movable such that a formed block can be released easily from the mold. A described compactable mold comprises at least one tube attached to at least one of the compacting wall structures. The compacting wall structures are operable to compact the mixture by moving toward the center of the mold cavity while the at least one tube remains stationary.

  • Patent number: 6481235
    Abstract: An ice-making device includes a case, an ice tray having a plurality of ice cubes and being rotatably installed clockwise and counterclockwise in the case, and a rotation stopping unit provided at the case and the ice tray to limit a rotation of an ice tray if the ice tray is rotated clockwise or counterclockwise within a predetermined angle in a state that the ice tray is poised horizontally. Since the ice tray can be rotated clockwise or counterclockwise according to a user's selection, the pieces of ice can be easily from the ice tray, ensuring that the user can separate the pieces of ice more conveniently.

  • Patent number: 4967995
    Abstract: A cover for an ice cube tray includes a top portion for covering the top of an ice cube tray and sidewalls joined to the top portion which permits the top portion to be raised to a position at which the top position is spaced above the tray top. The cover also includes flanges joined to the sidewalls for limiting the distance that the top portion can be raised above the tray top. Once the cover raised to its spaced, or elevated, position and the tray and cover are inverted and canted to an inclined condition, the top portion and sidewalls provide a chute for accepting ice cubes dropped from the tray and for directing the dropped ice cubes off the lower end of the cover.

  • Patent number: 4843827
    Abstract: A repetitive ice block or cube maker in which chilled water flows over a vertical evaporator to form ice blocks within ice freezing pockets of designated shape. The ice blocks are positively released by concurrently heating the evaporator while inducing a designated vibration in the evaporator. The vibration may be of sonic or ultrasonic frequency. A breather vacuum breaker vent may be provided in the bottom of each ice pocket. Each ice block is released with a minimum of heat being developed while heating the evaporator.
