Publication number: 20240118048Abstract: Preventing freezing in a heat exchanger can include passing first and second cooling fluids through the heat exchanger, monitoring a temperature and/or pressure of the second cooling fluid entering the heat exchanger, heating the second cooling fluid entering the heat exchanger by opening a valve when the monitored temperature and/or monitored pressure is below a trigger temperature and/or trigger pressure, and closing the valve when a condition is met. The first cooling fluid can have a first freezing temperature and the second cooling fluid can have a second, lower freezing temperature. Opening the valve can cause the second cooling fluid, in gaseous phase, to mix with the second cooling fluid, in liquid phase, upstream of the heat exchanger.Type: ApplicationFiled: October 5, 2023Publication date: April 11, 2024Inventors: Kiel Stephens, Galen Gerig, Steven A.

Patent number: 9720666Abstract: The disclosed embodiments provide a system for densely storing strings within the memory of a software program. During operation, the system receives a set of characters to be stored in a string, wherein each character is encoded using a multi-byte public encoding. The system then stores the set of characters in the string at least in part by performing the following steps. The system determines whether every character of the set can be encoded using a first private encoding that consumes less space per character than the multi-byte public encoding. Responsive to determining that every character of the set can be encoded using the first private encoding, the system stores a particular value associated with the first private encoding in a particular field of the string. The system then stores the set of characters in the string in the first private encoding.Type: GrantFiled: September 23, 2015Date of Patent: August 1, 2017Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Charles J. Hunt, Aleksey Shipilev, Brent A. Christian, Xueming Shen, Roger Stephen Riggs, Vladimir Kozlov
