Abstract: A plate heat exchanger includes a head, a housing, a frame, a pack, a follower, and a first tie bar. The housing has a driving mechanism. The frame is disposed between the head and housing. The pack includes a plurality of heat exchange plates. The follower is configured to slide along the frame and compress the pack between the follower and the head. The follower has a nut with internal threads. The first tie bar is disposed between the head and the housing. The first tie bar has external threads configured to mate with the internal threads of the nut. The driving mechanism is configured to rotate the first tie bar and the follower is configured to translate along the first tie bar in response to rotation of the first tie bar. A first telescoping cover is disposed between the head and the follower. The first telescoping cover is configured to cover the first tie bar and control the ingress and egress of fluid coming into contact with the first tie bar disposed within the first telescoping cover.

Abstract: A method provides a computer-implemented environment for improved educator effectiveness. The method includes a server serving, receiving, and storing web pages over a wide area network connected to client computers of administrators or teachers of a school, so the administrators or teachers can create, use or view processes and observation workflows to conduct performance reviews of teachers in the school.

Abstract: A computer-implemented, portable environment for in-class educator observation allows an observer to easily capture and date-stamp the observer's in-class observations of educator performance, and then to easily align such observations to template standards of an observation template, all in a way that allows the observer to focus on capturing details about the educator performance rather than on the data-gathering process.

Abstract: An example system for managing professional development plans may include a plan management module for receiving data representing a development plan for one or more users and an achievement module. The achievement module may determine one or more achievements associated with the development plan and may provide the one or more achievements to a user device of a first user. The achievement module may receive an association of an achievement selected from the one or more achievements with the goal-related aspect of the development plan and associate the achievement with the goal-related aspect of the development plan. The system may further include a reporting module for generating, based on associating the achievement with the goal-related aspect, a report describing the progress of the first user on the development plan.

Abstract: Various implementations for managing and providing interactive content are described. One example implementation includes a system having one or more processors, a communication unit, a content management engine, an interactivity module, and a reporting module. The communication unit sends and receives data over a network. The content management engine transmits a first instance of an interactive content dataset via the communication unit to a first client device of a first user for presentation. The interactivity module receives event data describing an interaction with the interactive content dataset from the first client device via the communication unit. The reporting module generates a report describing the interaction by the first user with the interactive content dataset and transmits the report via the communication unit to one or more of the first client device and a second client device of a second user for presentation.
