  • Patent number: 8870151
    Abstract: The present disclosure describes a pan formed from a base plate, a housing, a divider and an ejection plate. Together, the pan is shaped to form a pocket bun. The constituent parts of the pan nest together when baking, and disassemble when removing the bun from the pan. The pocket bun has an open-mouth design to allow ingredients to be retained in the bun while the sandwich is being consumed. The open-mouth design is formed having either a single cavity or a plurality of cavities, with each cavity adapted for carrying a filling. The pan is designed having one or more chambers, with each chamber adapted for baking a bun. Adjacent chambers optionally include openings therebetween such that adjacent buns will have a baked connection therebetween.

  • Patent number: 8623262
    Abstract: In a method for manufacturing components from composite fiber materials, at least one placeholder is inserted into a recess in a molding tool, wherein the unfinished component is subsequently produced, the placeholder is removed, at least one lifting pad is inserted into the recess and the unfinished component is removed from the molding tool by inflating the lifting pad. In a system for manufacturing components from composite fiber materials, the component removal process is monitored and controlled by a computer unit in order to prevent predetermined maximum component loads from being exceeded. The gentle component removal process makes it possible to avoid consequential costs for repairing or reworking the components.

    Abstract: The side walls of a mold have recesses in each of which is mounted a mold core for forming depressions on the outer side of a concrete block which is to be produced in this mold. The mold cores are pivotally supported around a horizontal axis which is parallel to the mold walls on the outer side of the mold. A sloping cam slot on each mold core is used to pivot the mold cores into the mold cavity defined by the mold walls and then back into the recess. The inner edges of a recess closely fit the mold core and function as strippers which self-clean all surfaces of the mold core which have come into contact with the concrete when the mold core is pivoted back into its recess. As a result, time intervals for cleaning the mold cores are greatly lengthened and a clean and smooth surface of the finished concrete block is insured.

A method for forming angled wells in a gel places the device in a gel forming material and allows the material to polymerize to form the electrophoresis gel slab. The device can be removed from the gel slab without distorting or tearing the gel and forming a plurality of substantially uniform sample wells oriented at an angle with respect to the edge of the gel slab. The sample wells are dimensioned to contain a liquid sample for electrophoresis separation. The gel slab can be rotated 90° so that the sample wells are oriented along a vertical edge of the gel slab with the sample wells retaining the liquid sample therein.

  • Publication number: 20020134525
    Abstract: A mold has outer mold parts and inserted molding material cores. Together, the parts and cores form a mold cavity. The inner cores of molding material are arranged in several layers one above the other. The inner cores are clamped in between the outer mold parts and a final covering core of mold material. A continuous clamping force is applied between the parts and cores. The mold cavity is formed by surfaces of the outer mold, surfaces of the inner cores and the covering core.

  • Publication number: 20020125403
    Abstract: The side walls of a mold have recesses in each of which is mounted a mold core for forming depressions on the outer side of a concrete block which is to be produced in this mold. The mold cores are pivotally supported around a horizontal axis which is parallel to the mold walls on the outer side of the mold. A sloping cam slot on each mold core is used to pivot the mold cores into the mold cavity defined by the mold walls and then back into the recess. The inner edges of a recess closely fit the mold core and function as strippers which self-clean all surfaces of the mold core which have come into contact with the concrete when the mold core is pivoted back into its recess. As a result, time intervals for cleaning the mold cores are greatly lengthened and a clean and smooth surface of the finished concrete block is insured.

  • Publication number: 20020009513
    Abstract: A guide block assembly is provided for retaining fiber bore forming pins and guide pin bore forming pins in precise relation to each other during the molding of a ferrule used in a multi-fiber connection. The assembly may include a top portion and a bottom portion with corresponding fiber and guide pin bore grooves formed on a surface of the top and bottom portions. When the top and bottom portions are assembled, the corresponding fiber and guide pin bore grooves form fiber and guide pin bores, respectively. The assembly may also include another portion that form additional bores with either the top or the bottom portion.

  • Patent number: 6299432
    Abstract: A mold for forming a dielectric housing for a card edge connector, wherein the housing has an elongated body defining a central slot for receiving a lower edge of a memory module. The elongated body has two lateral ends each formed with a tower for pivotably receiving an ejector for latching or ejecting the memory module received by the connector. A number of contact passageways are defined beside the slot for receiving a number of contacts therein for electrically engaging with golden fingers on the lower edge of the memory module. The mold has a gate located proximate to a lateral end face of one of the towers of the housing to be formed by the mold, and a number of core pins in the cavity for forming the contact passageways. The core pins located nearest to the gate have a cross section larger than that of the other core pins so that they are strong enough to withstand a fluctuation of a high pressure for injecting molten plastics into the mold.

  • Patent number: 6176465
    Abstract: This invention relates to an apparatus for baking letters of the alphabet and/or numerals. The apparatus includes a cake pan blank foldable into a cake pan, a grid insert template and one or more space-occupying insert blanks foldable into space-occupying inserts. The grid template insert contains removable grid-defined sections which sections are selectively removable so as to leave openings in the grid template insert. The space-occupying inserts are interfitted with the openings and the grid template insert and space-occupying inserts are then placed into the cake pan so that the volume of the cake pan not occupied by the space-occupying inserts takes the shape of a letter or numeral for receiving batter.

  • Patent number: 6090426
    Abstract: A novel food service package for containing a frozen concentrate for use in quick blending a drink of individual proportion is disclosed. The food service package of the present invention has a number of equally sized compartments with formed channels separating the compartments. Channels are formed under the dividers in the bottom of the package to provide a large surface are for rapid heat exchange so as to quickly temper the frozen concentrate in the package. A raised dome region is formed in the center of the package for rapidly dispersing the product dispensed from a single nozzle into each of the compartments. A gutter formed in each divider causes the dispensed concentrate to overflow from the compartments so as to rapidly self-level in the package.

  • Patent number: 5858262
    Abstract: A fully contoured three dimensional toy figure made of at least two figure parts, and a toy apparatus and a method for molding the toy figure are disclosed. The figure parts are molded in respective mold cavities with receptacles, e.g., holes, in a side thereof and selected parts are joined together with simple connectors inserted into aligned receptacles of adjacently positioned parts. The receptacles may simply be blind holes in one side of the figure parts, and the connectors may be simple rods, bars or tubes which may have structure that assists in engaging the walls of the holes. The invention allows small children to make fully-contoured toy figures easily without having to use adhesives or typical fasteners to attach the figure parts together. Child-safe plastic materials such as Plasti-Goop.RTM. may be used as the plastic molding material.
