  • Patent number: 4595367
    Abstract: An instructional globe facilitates the guided or self-directed study of terrestrial geography. A globe-shaped body is constructed so that major geographical features are represented on detachable appendages. Cues are provided for the proper placement of the appendages on the surface of the globe-shaped body, the cues consisting of niches, embossed or printed shapes, or indentations, unambiguously corresponding to the appendages. The globe-shaped body may be built up from a skeletal framework to hold a number of blocks, the blocks together forming a spherical surface. Appropriate portions of geographical features, or portions of cues, are formed on the blocks. A number of means are shown for attaching the blocks to the framework and the segments to the body. A series of embodiments apply the invention to the problems of teaching geography to students with varying or progressing learning skills.

  • Patent number: 4595181
    Abstract: Bent wire spring units for use in combination with a rectangular base frame embodying longitudinally-spaced, parallel, transverse support bars and a grid frame embodying a rectangular border wire and longitudinally and transversely-extending grid wires connected at their ends to the border wire and to each other at their crossings, each bent wire spring unit comprising upper and lower attaching elements connected to each other by integral lengths of wire resistant to bending and torsion. The bent wire spring units are transversely symmetrical from side to side and asymmetrical from front to back and are positioned transversely and longitudinally of the base frame and grid frame with their front sides on adjacent support bars facing and with their lower and upper ends attached, respectively, to the support bars of the base frame and the transverse wires of the grid frame. If there are an odd number of support bars, the spring units are alternately positioned in oppositely-facing directions.

  • Patent number: 4567713
    Abstract: A method of producing a package is provided wherein a product is brought into a depression formed using a shrinkable sheet material, a cover is brought over the depression, the sheet material is shrunk by heating and the depression is closed with a cover by heat-sealing. In order to shrink the depression free from creases onto different and irregular product surfaces steam is admitted to the sheet material having a saturation temperature above the sheet material temperature such that the steam condensing at the sheet material transfers its heat of condensation to the sheet material. The apparatus for performing the method comprises a sealing station with an upper tool and a lower tool movable relatively thereto and having a chamber for receiving the depression, the chamber being connected with a steam generator.
