Patent number: 11661698Abstract: Devices for dewatering washed laundry have a pressing membrane. The pressing membrane is releasably fastened below a ram plate of the device by way of a fastening ring. This connection is very complex by virtue of the heavy weight of the pressing membrane which has a diameter of approximately 1 m. In order for the fastening of the pressing membrane by way of the fastening ring below the ram plate to be facilitated, it is provided that the pressing membrane on the membrane collar thereof has at least one internal-side protrusion which while assembling the pressing membrane below the ram plate forms a bearing for the fastening ring. On account thereof, the fastening ring is temporarily supported below the ram plate while assembling the pressing membrane, this permitting easier assembling of the pressing membrane below the ram plate.Type: GrantFiled: January 19, 2021Date of Patent: May 30, 2023Assignee: Herbert Kannegiesser GmbHInventor: Jürgen Hildebrand

Patent number: 4612710Abstract: An apparatus for drying gel slabs supplies heat to a horizontal gel slab from a heating plate above the slab, while drawing a vacuum beneath. The heating plate is weighted and has a flat lower surface at least coextensive with the gel slab. The slab itself is placed on a porous support pad in a vacuum chamber enclosed at the top with a flexible cover which clings to the gel and seals to the perimeter of the chamber when a vacuum is applied from below. The heating plate rests on top of the cover under gravitational force, providing even heating across the entire expanse of the gel slab and for the entire duration of the drying process, resulting in a continuous and uniform vapor flow downward from the gel slab, a minimization of internal stresses, and reduced susceptibility of the gel to cracking.Type: GrantFiled: September 20, 1984Date of Patent: September 23, 1986Assignee: Bio-Rad Laboratories, Inc.Inventors: George G.

Patent number: 4188878Abstract: A restraining device is used in a dry kiln with a load of green lumber in order to reduce warpage during drying and cooling. A single restraint device is comprised of a pair of inverted leaf springs joined together at their centers and having a strap extending from one end of the top spring about the load of lumber and terminating at the other end of the top spring together with a tensioning device for the strap. Before the load of lumber is placed in the dry kiln, the tensioning device will draw down both the bottom and top leaf springs close to the load where the tensioning device will lock them in place. During drying, as the load shrinks, the top spring will be relaxed while the bottom spring will maintain a force across the width of the load, thereby substantially reducing warp.Type: GrantFiled: November 3, 1978Date of Patent: February 19, 1980Assignee: Weyerhaeuser CompanyInventor: Bruce L.
