Abstract: A novel carpet seaming tape and method for use in glue down carpet installations is provided. A carpet seaming tape having a paper carrier with a hot melt adhesive on its top surface and a pressure sensitive adhesive on its bottom surface is aligned beneath the abutting edges of two pieces of carpeting to be seamed, with the hot melt adhesive on top. The tape is attached to the floor using the pressure sensitive adhesive, the carpet pieces are removed and the floor is coated with general purpose adhesive everywhere except in those areas where the seaming tape has been attached. The carpet is replaced and realigned, and seaming is completed by using a seaming iron to melt the hot melt adhesive and pushing the edges of the carpeting pieces into the molten adhesive atop the carpet seaming tape so that the edges of the carpet closely abut each other.

Abstract: A process for coating a packaging film with a transparent barrier coating. The process starts with a metal substrate made of, or having a surface coating of, a valve metal or valve metal alloy. The metal substrate is anodized to form an anodic film of the valve metal on the metal substrate. The anodic film is made readily detachable from the metal by carrying out the anodization step in the presence of an adhesion-reducing agent, e.g. a fluoride. The packaging film is then attached to the anodic film and the anodic film is detached from the metal. The transferred anodic film forms a thin dense oxide coating on the packaging film that acts as a barrier against oxygen and moisture transport. The invention can be used for making packaging films suitable for packaging foodstuffs, and the like.

The rim of the first wheel is heated so that the material is sealed as it is drawn through the nip. A handle is affixed to the frame for carrying the rotary heat sealer and for supporting the heat sealer during its operation.

Abstract: A system for mounting a hub to an optical disk comprises a turntable arranged on an X-Y stage, a loading rod arranged above the turntable and extending vertically, a chuck provided at a lower end of the loading rod, for holding the hub with the axis of the hub aligned with a reference line as the axis of the loading rod, and a pair of displacement sensors for detecting a deviation of the axis of the turntable from the reference line, whereby the X-Y stage is driven in accordance with the signal from the displacement sensors, to position the turntable such that the axis of the turntable is aligned with the reference line. Thereafter, the optical disk is placed on the turntable with the axis of the optical disk aligned with the axis of the turntable, and the hub is placed on the optical disk through an ultraviolet-curing adhesive, by using the loading rod, with the axis of the hub aligned with the axis of the turntable.
