  • Patent number: 8968623
    Abstract: A method for demolding concrete blocks which are cast in a resilient mold supported in a rigid frame, the mold having a top surface and at least one cavity with an opening on the top surface, which cavity holds a cured cast concrete block. The mold has two opposing edges. The demolded blocks are stacked on a collection surface. A support is positioned over the cavity and the mold, the support and the frame are inverted and positioned in demolding apparatus. After two opposing edges of the mold are engaged by the demolding apparatus, the support is withdrawn to allow the mold to sag. The blocks may release from the mold and fall onto the collection surface. If any blocks remain in the mold, a plunger mechanism is pushed against the sagging mold to release the blocks. Guide members may facilitate positioning the blocks on the collection surface.

The deformation is sufficient to create a returning force that is greater than an adhesion forced between the solidified imprinting material and the mold. For example, the deformation may result from a pressure differential created between the mold and a side of the template disposed opposite to the mold. In this manner, the distortion may be undulations in the template of sufficient magnitude to contact a substrate upon which the solidified imprinting material is disposed.

  • Publication number: 20100119641
    Abstract: In imprint lithography, a mold having a pattern of projecting and recessed regions is pressed into a moldable surface on a substrate. The thus-imprinted moldable surface is permitted to at least partially harden to retain the imprint, and the substrate and mold are separated. In accordance with the invention, the substrate is separated from the mold by bending laterally distal regions (regions away from the center toward the edges) of the mold transversely away from the interface and transversely restraining the substrate. The mold can then be easily separated from the substrate by transverse displacement. The separation can be facilitated by providing a mold having a lateral dimension that on at least two sides extends beyond the corresponding lateral dimension of the substrate. Alternatively, the substrate can have a greater lateral extent than the mold, and the mold can be restrained. The distal regions of the substrate can be bent in the transverse direction.

  • Patent number: 7687006
    Abstract: A form for casting concrete blocks and other products having a resilient insert defining a cavity in which the block is cast and a rigid support or frame for the resilient insert. After the block has cured, the block is removed from the insert either by inverting the form to allow the block to fall from the insert or by lifting the block from the insert. One or more areas of the insert are tethered to the support with at least one generally flat flexible strap so that at least a portion of the insert is allowed to move a limited distance relative to the support and to deform to release the block. One end of each tether strap is embedded in the insert. After the cast block is separated from the insert, the insert is returned to a position wherein it is supported for casting another block.

  • Patent number: 7618578
    Abstract: A method and apparatus for forming a concrete block in form having a resilient insert forming a cavity in which the block is cast and a rigid support for the resilient insert. After the block has cured, the form is inverted. One or more areas of the insert are tethered to the support so that at least a portion of the insert can fall a short distance from the support. The weight of the cast block sufficiently deforms the insert to allow the block to fall free from the insert. When the form is again inverted to its upright position, the insert falls back into the support and returns to its original shape.

  • Patent number: 7563402
    Abstract: The present invention makes it possible to strip off a stamper stuck on a resin layer for groove formation during the manufacture of an optical disc from the resin layer without imparting damage or the like to the stamper. The present invention achieves this object by having the steps of bringing about a state in which the stamper protrudes from a substrate by a predetermined width, rotating the substrate with the back surface of the disc-shaped substrate attracted and held, elevating rollers capable of rolling relative to a contacting surface contacting with the protruding portion simultaneously with the rotation, and continuously applying a force working in a direction to separate the protruding portion from the substrate in the circumferential direction of the stamper.

  • Patent number: 7549616
    Abstract: A molding device is provided that includes outer and inner rubber molds that define a space therebetween for forming a column. Inserted within the inner mold is an elongated rigid member. A multisectional housing surrounds the outer mold and includes a plurality of sections that in a molding mode are secured together by fasteners. Once the column has been molded between the outer and inner molds, the fasteners are released allowing the sections of the housing to be relaxed or removed from around the outer mold. This permits the outer mold to expand or move slightly outwardly and in response to that outward movement, the pressure or force on the molded column lying between the outer and inner molds is reduced. This facilitates the extraction of the column from between the outer and inner molds.

  • Publication number: 20080220142
    Abstract: In order to make a granulated substance (G) of an aerated foodstuff, such as granulated meringue, said substance having an outer surface that appears continuous to the naked eye, an alveolar (18) structure (12) is provided, and a liquid precursor of the aerated foodstuff (for example, the so-called “meringue foamed mixture” in the case of meringue) is introduced (20, 22) into the cavities (18) of the structure. Consolidation of the precursor introduced into the cavities (18), obtained, for example, via heating (24), leads to the formation, in the aforesaid cavities (18), of respective particles of granulate (G), which are finally extracted from the cavities (18), typically exploiting the deformation of the material constituting the alveolar structure.

  • Publication number: 20080122144
    Abstract: In imprint lithography, a mold having a pattern of projecting and recessed regions is pressed into a moldable surface on a substrate. The thus-imprinted moldable surface is permitted to at least partially harden to retain the imprint, and the substrate and mold are separated. In accordance with the invention, the substrate is separated from the mold by bending laterally distal regions (regions away from the center toward the edges) of the mold transversely away from the interface and transversely restraining the substrate. The mold can then be easily separated from the substrate by transverse displacement. The separation can be facilitated by providing a mold having a lateral dimension that on at least two sides extends beyond the corresponding lateral dimension of the substrate. Alternatively, the substrate can have a greater lateral extent than the mold, and the mold can be restrained. The distal regions of the substrate can be bent in the transverse direction.

  • Patent number: 7331776
    Abstract: An impression device for food items. More particularly, the present invention is a stamping device designed to create images upon a variety of foods for decoration and/or marketing purposes. The stamper device of the present invention has the general appearance of a traditional rubber stamp, with large knob at the top to quickly adjust the depth of embossings. Small wings beside the knob provide an instant feature for orientation and comfortable ergonomic grip. The device provides both an emboss-only mode, and emboss-and-cut simultaneously mode, much in the manner of a cookie cutter. A simple snap means located at the bottom of the device functions to change such modes. Under the base of the device is a “socket set” style snap-in stamping die. As is the case with the roller device, the stamper device may be utilized for: 1) standard messages and images; 2) snap-in letters, which allows the user to assemble his or her own custom message; or 3) custom logos, messages, and images.
