Abstract: A rack-mounted KVM module is configured for a server rack. An L-shaped supporting frame, which has a vertical plane and a horizontal plane, is coupled to the sever rack. A flat panel display is coupled to the vertical sliding rail to move along the L-shaped supporting frame horizontally. A keyboard module is coupled to the horizontal sliding rail to move along the L-shaped supporting frame horizontally. A positioning mechanism is disposed in the horizontal sliding rail. The positioning mechanism consists mainly of an outer rail, an inner rail, a link bracket, a latch and a positioning switch. The latch is swiveled to engage a notch of the latch in a block portion of the outer rail or to remove the notch thereof from the block portion to respectively lock or unlock a fixed position when the link bracket is slid along the inner rail by moving the positioning switch.

Abstract: A sliding flat panel display and keyboard module for monitoring and controlling server computers on a server rack is described. The sliding flat panel display and keyboard module has an L-shaped supporting frame, a vertical sliding rail, a horizontal sliding rail, a flat panel display, and a keyboard. The vertical sliding rail and the horizontal sliding rail are respectively disposed on a vertical surface and a horizontal surface of the L-shaped supporting frame. The flat panel display couples to the vertical sliding rail and the keyboard couples to the horizontal sliding rail, so that the flat panel display and the keyboard are able to slide on the L-shaped supporting frame horizontally.

Abstract: Disclosed are high-ortho phenol-formaldehyde resoles having stable hemiformal groups. These resoles are of low viscosity, are essentially free of unbound water and volatile organic compounds. They are curable to phenolic formaldehyde resinous solids and are particularly suitable for use in liquid injection molding processes to form composites.

Abstract: There are described liquid compositions of a hemiformal of phenol and/or a hemiformal of a methylolated phenol with a miscible polymers such as phenol-formaldehyde resoles, phenol-formaldehyde, novolacs, aromatic polyesters, unsaturated polyesters, poly(aryl-ethers), aromatic polycarbonates urea-formaldehyde resins, or melamine-formaldehyde resins. The compositions are useful for forming thermoset plastic materials.

Abstract: This invention is directed to hemi-formals having the following formulas: ##STR1## wherein b is 1 to about 5, c is 1 to about 3, d is 0 to about 2, the sum of c and d does not exceed 3 and is equal to or greater than 1 and n has a value equal to or greater than 1. These materials can be used to manufacture phenolic resins and are adaptable to liquid injection molding processes.

Abstract: There are described composites containing from about 20 to about 70 weight percent of a reinforcing material, such as glass, carbon, graphite, or aromatic polyamide fiber, and from about 30 to about 80 weight percent of a thermosetting composition which contains hemiformals of phenol and methylolated phenol and a polymer miscible with the hemiformal.

Abstract: Disclosed are reinforced composites having a high content of reinforcing material such as glass fiber. They are made from liquid phenol-formaldehyde resoles containing a small amount of unbound water and volatile organic compounds.

Abstract: Latent catalysts comprising certain sulfur dioxide containing compounds such as bubadiene sulfone are used in the cure of thermosetting resins which are curable by an acid catalyst.

Abstract: Latent catalysts comprising the phenyl esters of certain carboxylic acids are disclosed for use in the cure thermosetting resins curable by an acid catalyst.
