  • Patent number: 4497137
    Abstract: A composite weather strip is disclosed having a semi-rigid elongated body and a relatively flexible extension formed in integral coplanar relation on a side edge of the body. The extension is laterally tapered to a feathered edge and has longitudinal ribs projecting from one surface of the extension. A foam tape attaches the body to one of two relatively movable surfaces, such as a frame surface and an adjoining surface of a window or door, adjacent a joint between the two surfaces. Whenever the window or door is closed, the flexible extension is engaged with the other of the two surfaces and, upon such engagement, is deflected to provide a positive seal against the passage of air through the joint in a sealing construction of exceptionally high integrity.

  • Patent number: 4346844
    Abstract: A stream of water introduced to a shower head is split into two paths. The first water path is discharged in the form of a cone shaped spray. The second water path is channeled into a chamber containing a rotor rotationally responsive to the flow of water into the chamber and which rotor includes a chopper for regulating pulsed discharges of water through varying ones of a plurality of discharge ports. The proportional water flow in the two water paths is selectively variable. Air is introduced to the stream of water upstream of the water path split to aerate the water and reduce the quantity of water flow without an apparent water flow reduction to a user. A non-pulsating aerated shower head is also described.
