The present technology provides an illustrative display post that includes a first side, a second side, and a third side. The third side of the display post has a concave portion extending along a length of the third side such that the concave portion is configured to receive a convex surface. The third side also has a first flat portion along a side of the concave portion and extending along the length of the third side and a second flat portion along an opposite side of the concave portion as the first flat portion and extending along the length of the third side.

A housing for a hearing aid appliance includes a housing shell which is made, at least in a partial region, from a material which forms a smooth exterior surface in the partial region. Recesses are formed in the material beneath the smooth exterior surface. A material layer located between the recesses and the exterior surface has such a layer thickness that the material layer is at least semitransparent for light, as a result of which the recesses are visible through the material layer when the housing shell is illuminated. A hearing aid appliance having such a housing shell is also provided as well as a method for producing such a housing shell for which a rapid-prototyping process is employed and by which the recesses are produced by not solidifying the starting material there.

To produce a signal plate for a railway signal, a casting mold corresponding to an external form of the signal plate is provided. At least one luminous point is inserted into the casting mold, and the casting mold is filled with a free-flowing curable plastic to create a casting. The plastic is cured, and the casting is removed.

A sign frame comprises a pair of upstanding leg members each having a proximate end and a tapered distal end, at least one top member connecting the leg members at the proximate ends thereof, and at least one cross member connecting the leg members between the proximate and distal ends thereof. The members together define a first sign mounting area. Within the sign frame is at least one mounting flange extending into the first sign mounting area from the sign frame, and at least one elongated stiffening rib upstands from and extends along each of the leg members.

This invention relates to an object having a display panel embedded in its top surface and processes for its manufacture. This invention also relates to an in-mold display transfer film or foil, which comprises a temporary carrier film, a release layer, a display panel, an adhesive or tie layer and optionally a durable layer.
摘要:
A process for the manufacturing of a board, used as a core, forming a carrying structure for decorative laminates. Particles are achieved by grinding cured, and possibly foamed, rigid, polyurethane, polyisocyanurate and/or phenolic resin so that it passes through a 2 mm screen, preferably a 1 mm screen. The particles are allowed to absorb a selected amount of water in the range 1-7% by weight, 85 parts per weight of particles is mixed with 2-15 parts per weight of a bonding agent, the bonding agent selected from the group consisting of, a) a mixture of polyols, such as polyester or polyether, crude methylene diphenyl diisocvanate, or, b) a formaldehyde based resin such as phenol-formaldehyde resin, ureaformaldehyde resin, melamine-urea-formaldehyde resin, melamine-urea phenol-formaldehyde resin or phenol-resorcinol-formaldehyde resin, or c) polyvinyl acetate resin, and that, the mixture is applied in a press, possibly with at least one intermediate carrier web, whereby a slightly porous and preconditioned core with a selected water content in the range 0.8-6.5% is achieved. The invention also relates to a decorative laminate achieved through the process.
