Title: Process for conducting etherification reactions.
Inventor: HARRIS WILLIAM I
IPC: C07C41/06
Filed: 1998-04-08
Abstract: An improved process for conducting an etherification reaction of alcohols with olefins has been discovered. The process employs a macroporous strong-acid, cation-exchange resin catalyst prepared at a temperature of 120 degree C or higher with a reduced amount of divinylbenzene cross-linker. The etherification catalysts produced in the invention display equivalent or superior catalytic activity than conventional catalysts and are less expensive to produce than conventional catalysts due to reduced amounts of cross-linker.

Patent NL-2004159-A (NL)
Inventor: MAAS WILHELMUS JOHANNES JOSEPH
IPC: B67D1/08
Filed: 2010-01-28
Abstract: Methods and systems for the dosed dispensing of a liquid from a container connected to an outflow channel closable by a liquid valve are presented. Such methods include opening the liquid valve, dispensing a measure of liquid from the container through the outflow channel, closing the liquid valve, and blowing out the outflow channel after closing the liquid valve. For example, during or after closing of the liquid valve the outflow channel can be connected to a gaseous source, the gas at a pressure greater than atmospheric pressure. Or, for example, where Flair™ technology is used, a limited quantity of a displacing gas can be guided to the outflow channel during or after closing of the liquid valve, or can be guided into an intermediate chamber connected to the outflow channel during or after closing of the liquid valve.

Title: Metal coil handling hook for overhead crane - is suspended by cranked levers acting on spring to hold it level
IPC: B66C1/24
Filed: 1975-03-19
Abstract: The C-shaped hook is suspended on cranked levers (6, 9) from a hoist block.

Title: Drive for stirrer to aerate effluent - with the power transferred via one large gear to reduce breakdowns
IPC: B01F15/00
Filed: 1976-03-01
Abstract: A drive for the stirring, aerating mechanism of an effluent aerator transfers the power via an output shaft. The output shaft is coupled to a turntable. The drive gear train normally has a number of small gears which are vulnerable and causes stoppages when the load changes suddenly as it does in effluent treatment. Hear the power is transferred to one very large gear (the turntable) so that the equipment is much less likely to breakdown as a result of load changes.
