Example ambulation aid apparatus and associated methods of manufacture are disclosed and described herein. An example single-point supportive ambulation aid is formed as an integral part. The integral part of the example ambulation aid is formed to integrate: a body portion formed to support a user; a graspable area integrated with the body portion and providing an area to be gripped by a user; and a foot portion integrated with the body portion and providing a single point of contact with a walking surface to facilitate user movement and support in conjunction with the body portion and graspable area through the integral part.

A forming station for a thermoform packaging machine, wherein the forming station comprises a forming tool upper part and a forming tool lower part that are each configured for cooperating so as to thermoform a film positioned between the forming tool lower part and the forming tool upper part. The forming station includes a first change bar that is adapted to be releasably attached to a reception area of the forming tool lower part and the first change bar carries a plurality of punches or blades.

A tray appliance of the present disclosure has a first dissolvable sheet and a first substance formed within a second dissolvable sheet. The first dissolvable sheet is laid on the second dissolvable sheet and is formed into a first dissolvable negative impression of a person's teeth, gingival tissue, or other soft tissue, such that when first dissolvable negative impression is worn by a person, the first dissolvable negative impression dissolves and releases the first substance into the person's saliva, teeth, gingival tissue, or other soft tissue.

A composite core structure includes a core having a plurality of elongated fibers and a plurality of spherical members, the elongated fibers and spherical members consolidated into a desired molded shape. The composite core structure also includes a matrix material encapsulating the elongated fibers and spherical members.

A thermoforming device heats a plastic film to a substantially uniform temperature, in order to impart a curved shape to said film. The device includes a chamber, the internal pressure of which is variable and which is closed by the film, a system for measuring a sag in the film arranged outside the chamber and opposite said film, and a system for heating the film. The heating system includes a hot air blowing unit which is suitable for producing a hot airflow flowing parallel to the film between two opposite edges of said film.

A free-standing plastic livestock confinement system includes hollow plastic panels assembled together to provide interconnected walls that create confinement areas. One of the walls provides a door opening and a door that can be closed across the opening. The door is a hollow plastic panel with an opening for an animal to place its head through for access to food. The door is molded with a bucket holder and the opening in the door over the bucket holder. The bucket holder is recessed such that a bucket received in the bucket holder will extend partially into the confinement area.

An apparatus and related method of utilizing articulating vacuum plates to manipulate a film or polymeric sheet and form a three dimensional article is provided. The apparatus can be in the form of an articulating vacuum plate system which includes one or more plates or mold parts that are configured to support a sheet, constructed for example, from a polymeric film, in a two dimensional configuration or a three dimensional configuration in a first mode. The apparatus is constructed so that the plates and/or mold parts can articulate or move so as to reconfigure the sheet from a generally planar configuration into a second three dimensional configuration in a second mode for further forming, optionally while the plates and/or mold parts apply vacuum to the sheet while the plates and/or mold parts articulate, so that the plates and/or mold parts bend or otherwise manipulate the configuration and shape of the sheet.
