Title: Shoe heel spring and stabilizer plate
Inventor: CLAVERIA RIC Y
IPC: A43B21/30
Filed: 1991-04-11
Granted: 1996-09-24
Abstract: A thin, heel-sized plate formed of a composite sandwich of thermoplastic resin and carbon-glass fiber cloth has a pair of upwardly-flanged lateral edges, front and rear ends, and an integral, rearwardly-extending, upwardly-inclined, vertically-acting spring member appending from it.          The device is encapsulated within the resilient material of the heel portion of the midsole of an athletic shoe such that the spring member is disposed below the calcaneus of the wearer's foot.

Title: Earstem for eyeglasses
Inventor: JANNARD JAMES H
IPC: G02C3/00
Filed: 1990-10-19
Granted: 1998-05-12
Abstract: Earstems (20) for eyewear are configured to define a lateral distance between the earstems which is greater than the width of the head in the anterior temple region so as to prevent any contact of the earstems and the head in that region.  Preferably, the earstems include a diverging section (22), a transition section (24), a converging section (26) and a retaining section (28), wherein the transition section defines the greatest lateral distance between the earstems.

Granted: 2000-09-26
Abstract: A high density, single pass heat exchanger (26) is provided which is designed for drying products such as bakery wastes, alfalfa, peat moss, wood or similar fibrous products. The exchanger (26) has a series of circumferentially spaced, inwardly directed heat transfer sheet metal flights (48) presenting a central flight-free zone (74), together with a series of baffles (282-288) in axially spaced relationship along the length of the exchanger (26). A number of annular deflectors (294-298) are mounted within the exchanger (26) between adjacent baffles (282-288), such that the baffles (282-288) and associated deflectors (294-298) cooperate to cause the material being dried to follow an essentially serpentine, generally helical path (300). The exchanger (26) is capable of efficiently removing moisture from wet products by virtue of the fact that the diameter (R) of the exchanger (26) to the diameter (r) of the internal flight-free central zone (74) is from about 1.4-2.4. The disclosed exchanger design may be used for updating existing three-pass and single-pass dryers, or for the fabrication of new systems.

Inventor: DAMRAU WAYNE A
IPC: B05D1/26
Filed: 1993-07-27
Granted: 2000-10-24
Abstract: A fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move toward one side of the sheet away from the curved surface. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact an opposite relatively air-free side of the coating liquid sheet against the web surface while the one side of the sheet is out of substantial contact with the web surface. Contacting the web with coating liquid that is relatively free of entrained air minimizes the occurrence of skip coating on the web, especially when the web is traveling past the applicator at high speeds.
