Abstract: A purchasing agent application operates on a mobile device to facilitate a user's purchase of a product featured on a web page of a third party merchant for a gift recipient. The user can select an option in a web browser to share the web page URL with the application. The application communicates with a server to streamline the purchase process based on previously entered user identity, payment and shipping information. The application and/or server use machine learning models to automate the completion of any one or more form fields and/or link selections that the user would otherwise be required complete on the third party merchant's web site to execute the purchase. None of the user, the application or the server need have any prior relationship with the third party merchant. The machine learning models can be trained, for example, using supervised learning, unsupervised learning and/or reinforcement learning techniques.

Abstract: A shell and tube heat exchanger for exchanging heat between a shell side fluid and a tube side fluid has a longitudinally extending shell, a longitudinally extending tube bundle and one or more baffles positioned within the shell for directing the shell side fluid to flow across the tube bundle. One or more valves is also provided within the shell of the heat exchanger. Each valve is operable between a first position and a second position and co-operates with a baffle for adjusting the flow of shell side fluid through the shell side of the exchanger. Each of the valves is controlled by an external actuator.

Abstract: Disclosed herein is apparatus including all of the components present in a conventional internal combustion engine such as body forming cylinder walls that define a primary combustion chamber, a piston reciprocable in the cylinder between compression and power strokes, intake means for introducing fuel charges into the primary combustion chamber, ignition means for igniting fuel charges and exhaust means for removing residual gases from the primary chamber after ignition of each fuel charge. Added to these conventional engine components is a housing that defines an auxiliary combustion chamber and an orifice that provides communication between the primary and auxiliary combustion chambers.
