Title: Hydrolysis of dialkyl carbonates
Inventor: CRANDALL JOHN WORTH
IPC: C07C29/09
Filed: 1986-12-10
Abstract: A process is provided for the utilization of dialkyl carbonates formed as by-products in a continuous process for the synthesis of oxalic acid esters from nitrous acid esters and carbon monoxide and wherein the esters are subsequently used as intermediates in the production of commercially useful products, such as ethylene glycol. The process comprises contacting a mixture containing the by-product comprised of a dialkyl carbonate with an aqueous solution of a metal carbonate under hydrolyzing conditions whereby the dialkyl carbonate is converted to the corresponding alkanol and the metal carbonate is converted to metal bicarbonate. Upon distillation of the alkanol from the mixture the bicarbonate is converted back to the metal carbonate which can then be recycled from the bottoms to the hydrolyzing zone for use in further hydrolysis of by-product. The alkanol is recycled for use in the continuous process.

Title: Apparatus for operating sliding windows
Inventor: WALTERS JOHN EDWARD
IPC: E05F11/46
Filed: 1987-06-18
Abstract: A lazy tong linkage suitable for operating sliding windows in vehicles, e.g. cars, is operated by a threaded shaft (12) in engagement with a nut (14a) and a bearing member (14b) mounted at opposite pivot points of the linkage so that rotation of the shaft, e.g. by an electric motor, moves the nut and member towards or away from one another to operate the linkage. The nut and member are mounted on pins (8b) which slide in their slots (16), and have cam faces (20) diverging upwardly outwardly from the slots (16). When the linkage is fully closed the face (20) are adjacent projecting outer pivot pins (8a). As the shaft (12) is rotated to move the nut (14a) the faces (20) cam the outer pins (8a) away from the mounting pins (8b) to initially open the linkage. Subsequently the linkage is opened in the usual way. The shaft may be rotated by an electric motor, e.g. mounted on the bearing member (14b) to rise and fall with the linkage. <IMAGE>

Title: Process for fabricating mos devices
Inventor: MA DI
IPC: H01L29/78
Filed: 1989-01-03
Abstract: A layer of material 20 such as silicon dioxide that serves as an etching stop during the side wall spacer etch, is inserted between the silicon substrate 10 and the side wall spacer 24. In another embodiment after establishing differential layer thicknesses of silicon dioxide on the source/drain surface, the side wall spacer is completely removed and light and heavy ion implantation steps are performed sequentially with one single lithographic step. In a further embodiment after a self-aligned silicide layer is formed on the source, drain and gate the side wall spacer is removed, and light and heavy ion implantation steps are sequentially performed. The etch stop material 20 and the side wall spacer material 24 have different etching characteristics, so that the side wall spacer material can be etched to form the side wall spacer without the need to control the etching depth accurately in order to avoid undesired etching of other materials. <IMAGE>
