Abstract: In a computer system, peripheral computers with business applications send alert messages to a central computer when a current variable exceeds a reference value. The central computer implements an alert server to notify a target group of multiple users via communication devices. The central computer escalates further notification to a supervisor user in the event that during a predetermined time period no user of the group has confirmed reception. The notifications have predefined fixed and variable text portion that relate to the alert type. The group of users to be notified is determined by subscription or by a role-to-application assignment.

Abstract: A warp formed of a multiplicity of parallel filaments is wound on a warp beam by an apparatus having a supply of the warp, a transport roller, and an adjustment roller adjacent the transport roller and movable between a holding position engaging the transport roller and a winding position spaced therefrom. The warp extends from the supply along a path around the transport roller, hen around the adjustment roller, and then around the warp beam. The beam and transport roller are rotated to displace the warp along the path and wind it up on the beam while maintaining the adjustment roller in the winding position. Tension is detected in the warp at least during winding of the warp on the beam and the adjustment roller is displaced during winding of the warp on the beam in a predetermined first direction transverse to the path to increase and decrease the tension to maintain the tension within a predetermined range when the adjustment roller is not in the holding position.

Abstract: A warp beamer having a frame supported on the floor and a horizontal warp beam rotatable on the frame has a step assembly provided with a step displaceable between a lower position supported directly on the floor and an upper position spaced well above the floor and of the warp beam. A motor connected between the step and the frame displaces the step between its positions. The step rides on a vertical guide on the frame and a lever assembly pivots the step between a horizontal position in the lower position and a generally vertical position in the upper position.
