Title: Efficient dryer and drying process
Inventor: PETROS KENNETH W
IPC: F26B3/04
Filed: 1987-12-04
Granted: 1992-06-09
Abstract: ABSTRACT OF THE INVENTION      Apparatus and process for drying coated surfaces, e.g. inked surfaces, with improved efficiency.  The apparatus comprises an air-directing baffle which has vortex-inducing means, e.g. grooves or slots therein.  The slots are arranged substantially perpendicular to the general direction of flow of drying gas through a drying zone formed by the baffle and the surface being dried. The vortices provide both (1) improved drying efficiency at the interface between coated surface and drying gas and (2) effective dissipation of kinetic energy from the drying gas as it traverses the drying zone.  Less energy is required to exhaust spent drying gas from the drying zone while effectively preventing the gas from escaping into the environment.  In dual-drier systems, fed by centrally located air nozzles, means is provided to avoid an asperating effect which tends to suck the web toward the apparatus.  In systems to be used with flat webs and especially unsupported flat webs, the air directing baffle means are best made approximately parallel with said flat web.

Granted: 1991-11-19
Abstract: ABSTRACT OF THE DISCLOSURE          A saturator of the type which includes a chamber situated between a chamber defining element and a mandrel, in which a web is moved through the chamber to impregnate the web with a saturant contained in the chamber, includes a chamber defining element which de-fines an array of grooves.  The grooves are separated by raised surfaces.  The raised surfaces cooperate with the mandrel to pressurize the saturant in a high press-ure zone which causes a relatively large amount of saturant to enter the web.  The grooves define respec-tive low pressure zones, which cause a reduced amount of saturant or no saturant to impregnate the web.  A desired pattern of impregnation of the web can be obtained by properly positioning the grooves with respect the raised surfaces on the chamber defining element.

IPC: E04C5/18
Filed: 1988-10-19
Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE           A spacer for concrete wire reinforcement is comprised of a heavy gauge, flat metal spring steel band, having a hook at one end for receipt of one of two parallel wires of a wire mesh, and a curved and hook-like opposite end which can be resiliently forced into position under the second wire to securely retain the spacer in position.  A generally V-shaped projection is provided on the spacer to position the wire mesh at the desired distance from the surface of the concrete mold.  The apex of the projection is formed to have a convex wide-radius "ball-bearing" shape. This shape lends increased strength to the spacer and also results in a greatly reduced area of contact between the spacer projection and the mold wall.  The spacer also includes a tall-like extension on the second hook-like opposite end, which extension coacts with a pronged tool during installation of the spacer on a wire mesh.
