Abstract: METHOD AND APPARATUS FOR HOT-PRESSING OF A WEB       ABSTRACT OF THE DISCLOSURE      Method and apparatus for pressing and dewatering a paper web, in which a hot-pressing stage is utilized where the wet paper web is pressed in direct contact with a cylinder face that has been heated to a temperature higher than about 100°C.  A relatively long pressing time and a relatively low compression pressure are applied in a pre-heating/pre-pressing stage.  In this preliminary stage, a surface layer of the cylinder that heats the paper web is heated to a temperature higher than about 100°C.  In the immediately following stage, the compression pressure applied to the paper web is lowered so that vaporization of the water present in the paper web is intensified.  Next, the web is passed substantially immediately into an intensive nip-pressing stage in which the web is pressed with a peak pressure, preferably higher by one order, so that water vapor is blown through the paper web, thereby causing some of the water present in intermediate spaces between fibers in the web to be blown out, and intensifying dewatering.

Abstract: Abstract of the Disclosure Methods and apparatus are set forth for fabricating a concrete panel with embedded glass block.          According to the invention the panel form includes at least one partially anchorable support form, i.e. a support form having an anchorable portion and a removable, nonanchorable portion.  After concrete is poured into the panel form and hardened, the nonanchorable portion of the support form is removed.  A noncementitious band (or collar), of which the anchored portion of the support form is comprised, remains.  The glass block is then inserted within this band.  According to the preferred embodiment of the invention a rubber seal may be inserted between the glass and noncementitious surface to both waterproof the panel and cushion the block to improve the completed panel's ability to be handled and transported without damage.  Furthermore, the invention teaches utilizing the support form to create at least one support lip.  Each lip may be formed as part of the anchored band or as part of the formed concrete panel.  The lip(s) provide support upon which to rest the block and improve the panel's load bear-ing capacity.  A given lip may take any number of shapes and can be designed to take advantage of the inherent load bearing capacity of the concrete in which it is set and/or formed to support the anticipated load.  Additional glazing and sealing steps may be optionally performed to further cushion the block and hold it firmly in place.

Granted: 1995-01-03
Abstract: An  apparatus  for  applying  dental  agents  to  tooth surfaces. The apparatus includes a syringe-type dispenser for holding a quantity of dental agent and an applicator tip having adjustable bristles at one end.  The applicator tip is curved to accommodate access to tooth surfaces undergoing restorative  dental  procedures.     The  bristles  are  in communication  with  the  syringe-type  dispenser,  thereby allowing the dental agent to be continuously applied to the tooth surfaces without the need to stop the procedure and rewet the applicator in a dental agent source.  The syringe-type applicator permits accurate control of the amount of dental agent applied to the tooth surface.  In this way, the tooth  surface  receives  neither  an  excessive  nor  an insufficient amount of the dental  agent.   Moreover,  the bristles may be pushed in to permit the dental agent to be precisely applied to a very small tooth surface, such as pits and fissures, or pulled out to permit the bristles to fan out for application of the dental agent to larger tooth surfaces.

Date May 7, 1987.The invention relates to a multi-ply wood product. The supply of wood suited e.g. for the production of plywood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insufficient adhesion between the coating and the wood. For the elimination of these problems, a multi-ply wood product has been developed in which at least one layer is formed by a crude fiber ply blank comprising haphazardly oriented fiber material as well as bonding agents, additives and filler materials. A single hot-pressing step in connection with the production of the multi-ply wood product forms this blank into homogeneous ply (14) which, by virtue of the partial splitting of the fiber structure and the resulting reorientation, which take place during the hot-pressing, fills the irregularities in the surface of an adjacent wood layer (1) and forms a tight synthetic ply of accurate dimensions.
