Filed:

Jun 9, 1995

Appl. No.:

8/488810

Inventors:

Alan J. Adams - Shelton CT
Richard M. Lacouture - Ansonia CT
Robert J. Ferraro - Monroe CT

Assignee:

Johnson Industries, Inc. - Trumbull CT

International Classification:

A47B 300

US Classification:

108129

Abstract:

A folding and latching mechanism for a table leg includes a recess into which a latching pin is moved when the leg is erected. A spring-loaded latching bar includes a camming surface which bears against the latching pin on a diagonal tangent. The force applied by the camming surface thus has a component tending to seat the latching pin securely into the recess throughout the time the table is in its erected condition.

US Classification:

540110

Abstract:

This invention concerns a method of substituting a chlorine atom for a predetermined hydrogen atom located within an organic compound which comprises contacting the organic compound containing the predetermined hydrogen atom with an esterifying agent comprising a pyridine ring or a substituted or fused ring derivative of a pyridine ring so as to produce an ester and treating the ester with a chlorinating agent so as to substitute the chlorine atom for the predetermined hydrogen atom. The ester comprises the pyridine ring or the substituted or fused ring derivative of the pyridine ring so positioned within the ester with respect to the predetermined hydrogen atom that a chlorine atom attached to the nitrogen atom of the pyridine ring or substituted or fused ring derivative of the pyridine ring reacts with the predetermined hydrogen atom. Another aspect of the invention is a method for converting a predetermined single bond between a carbon atom and another atom in an organic compound into a double bond between the carbon atom and the other atom which comprises substituting a chlorine atom for a predetermined hydrogen atom bound to the carbon atom or the other atom of the organic compound according to the method of this invention so as to produce a chlorine-containing compound and then treating the chlorine-containing compound so as to eliminate the chlorine atom from the compound and form the double bond.

US Classification:

100147

Abstract:

A height adjustment mechanism for a table top generally comprises two leg assemblies each having a base and two vertical columns, a slidable post assembly on each leg assembly with the slidable post, assemblies supporting the table top, and a drive for raising and lowering the leg assemblies and supported table top. The slidable post assemblies have opposed covers which frictionally engage the vertical posts to hold the table top at an adjusted height. The drive is a lack screw and jack nut in each leg/slidable post assembly, wherein the jack screws are connected by a chain and sprocket drive and are driven by a crank.
