Publication number: 20160041565Abstract: A control module can include in at least one implementation an electronically actuated water control valve configured to shut off water flow through a water pipe, an electronic flow sensor configured to measure the flow of water through the water pipe, a temperature sensor configured to report water temperature, a water quality sensor, and a processing unit in communication with the electronically actuated water valve and the electronic flow sensor. The processing unit can be further configured to identify irregularities in the flow of the water through the water pipe, and in response to the identified irregularities, shut off the water flow through the water pipe.Type: ApplicationFiled: January 7, 2014Publication date: February 11, 2016Inventor: Philip D. Edwards

Patent number: 5532366Abstract: The present invention relates to certain novel amide derivatives which are pyrido[3,4-d]pyrimidin-7-ylacetamides which are inhibitors of human leukocyte elastase (HLE), also known as human neutrophil elastase (HNE), making them useful whenever such inhibition is desired, such as for research tools in pharmacological, diagnostic and related studies and in the treatment of diseases in mammals in which HLE is implicated. The invention also includes intermediates useful in the synthesis of these amide derivatives, processes for preparing the amide derivatives, pharmaceutical compositions containing such amide derivatives and methods for their use.Type: GrantFiled: January 19, 1995Date of Patent: July 2, 1996Assignee: Zeneca LimitedInventors: Philip D. Edwards, Peter Warner, Donald J. Wolanin
