Inventor: SANDUJA MOHAN L
IPC: C09D5/00
Filed: 1995-11-30
Granted: 2000-02-01
Abstract: This invention relates to the coating of steel parts with organic polymeric materials for resistance to corrosion, abrasion, impact, salt solutions of high and low pH (both in liquid as well as vapor state) and corrosive atmospheric gases under the environment of high relative humidity and ambient conditions of temperature and pressure. To obtain secure and permanent adhesion of the coating on the steel article a polymeric coating is formulated so as to achieve chemlcal grafting to the steel face. This involves the use of monomers prepolymers, catalyst and a graft initiator system. The monomers are preferably polyfunctional and when applied onto a metallic substrate, react via graft polymerization with the metal to form a polymerized layer coated onto the surface of the steel substrate. The monomers and prepolymers are so selected that when polymerized onto steel the coating has substantially zero moisture vapor-gas transmission rate and consequently acts as a barrier to moisture, oxygen and other gases from coming in contact with the surface of the steel substrate thereby improving the protective potential of the coating. Fillers may be included in the coating material to enhance physical or wear characteristics. Other components that can be added are slip agents wetting agents, thixotropic promoters and adhesion promoters. This coating process is particularly advantageous for use with steel parts used in the manufacture of cranes.

Abstract: An anchored/resilient floor system includes at least one upper flooring layer supported by parallel rows of attachment members which are supported above a base by a plurality of compressible pads, the attachment members being secured to the base at predetermined positions therealong by a fastener construction which permits downward deflection under loaded conditions but prevents vertical raising of the members beyond their initial static position. The attachment members are anchored in a manner which does not hold the pads in a precompressed state when the floor is unloaded. The fastener construction is preferably a plurality of single-piece anchor pins, wherein each anchor pin has a depth stop which limits downward extension into the bore during installation. This single-piece anchor pin construction is particularly suitable for reanchoring or retrofitting an already installed floor at a significantly lower cost than that of installing a new floor, and the one-piece anchor pin may be adapted for use with a portable floor by using internally threaded anchors embedded in the base.

Title: Contact element and ceiling element for a heating and cooling ceiling
Inventor: SOKOLEAN HELMUTH
IPC: F24D19/00
Filed: 1996-10-04
Granted: 2006-02-28
Abstract: In order to improve the heat-conducting connection between a contact element (3) and a ceiling panel (1) which are adhesively bonded to one another, the contact panel (5) of the contact element (3) is provided with an adhesive depression (10) in the contact surface (6), said depression taking up only part of said contact surface, while the remaining part of the latter rests directly against the upper side of the ceiling panel (1). The contact panel (5) may be elastically or plastically deformable, e.g. along a bending groove (9), with the result that it adapts more easily to irregularities, such as those caused, for example, by slight sagging of the ceiling panel (1). This permits larger widths of the contact panel (5) without impairing the thermal contact. In order to ensure close abutment of the parts of the contact surface (6) which are not adhesively bonded to the upper side of the ceiling panel (1), the contact panel (5) can be appropriately prestressed.
