Filed:

Mar 3, 2008

Appl. No.:

12/074458

Inventors:

Donald Bell - Orange CA, US

International Classification:

E05C 9/00
E05C 5/02

US Classification:

292 6, 292 71, 292219

Abstract:

With the adoption of this new modern latching system, (FIG. ) closing and latching a pocket door will be just as simple and convenient as closing and latching a swinging door, irregardless of the physical capability of the operator. This system has been masterfully designed and engineered with appropriate lever handles that are prominently mounted on the face of the door, where they will be convenient to use by people of all ages and physical encumbrances. Coupling these handles to a reliable automatic latching embodiment and complementing the completed assembly with door guides , promises to be a bold step forward in latching concepts for modern interior pocket doors.

Assignee:

Ethyl Corporation - Richmond VA

International Classification:

C10M13300

US Classification:

508188

Abstract:

Multifunctional additives having a variety of advantageous properties are described. They are formed by a process which comprises heating concurrently or in any sequence a) an oil-soluble ashless dispersant containing basic nitrogen with b) an alkoxylated alcohol of at least 8 carbon atoms c) a borating agent and optionally d) an inorganic oxyacid or anhydride of phosphorous. The reactants are in proportions on an active ingredient basis of about 0. 03 to about 0. 35 part by weight of b) per part by weight of a), and about 0. 005 to about 0. 06 part by weight of boron as c) per part by weight of a). The reaction temperature can range from about 50. degree. to about 150. degree. C. Water and/or solids present in the resultant mixture can be removed. Preferably, the optional phosphorous component is used in the formation of these additives. This phosphorous component can be an inorganic oxyacid or anhydride of phosphorous.

International Classification:

C10M10568
C09K 504

US Classification:

252 68

Abstract:

A refrigeration lubricant suitable for use with R-134a-type refrigerants comprises at least one dialkanolamine diester-amide oil corresponding to one of the formulas: ##STR1## in which formulas R is a hydrocarbylene group containing 1-10 carbons; n represents zero or one; each R' is independently selected from alkylene groups containing 1-10 carbons; R" is hydrogen or a hydrocarbyl group containing 1-10 carbons; and each G, when not linked with another G, is independently selected from hydrocarbyl groups containing 1-10 carbons or, when linked with another G, is a hydrocarbylene group which, together with the colinked G, forms a hydrocarbylene group containing 1-10 carbons.
