Abstract: A method and apparatus for performing combined single differential thermal analysis and dynamic mechanical analysis of a sample relative to a reference, using either one reference measurement for a sequence of material measurements--whereby the reference can also be represented by an empty weighing pan--or by the use of a mathematical model which is so determined that it takes the real behavior of the thermal analytical apparatus into account. Reference temperature curves are generated relative to time of an empty furnace or a reference sample contained in the furnace, and temperature curves of a sample to be measured are taken at the exact same location in the furnace. The reference and sample temperature curves are compared to determine the temperature difference.

Abstract: A portable hand-held battery-powered crimping tool includes a gear housing containing a through bore receiving a driven gear having a crank arm that is connected by a drive link with the common pivot axis of a toggle device that pivots a pair of crimping jaws from an open released position toward a crimping position. The gear is driven by a reversible direct-current motor that is supported on the hand-held handle together with a battery pack. A releasable overrunning clutch is operated by a push button on the handle to disengage the motor drive from the drive link, whereupon the crimping jaws are pivoted toward the open released position by a biasing spring.

In order to prevent an obstruction at the front end of the front container, the front cover drive device is mounted forwardly of the front wall of the front container, and a tarp storage tray is provided for storing the tarp when in the collapsed open condition. In order to minimize the extent to which the idler pulleys protrude laterally beyond the side walls of the rear container, the idler pulleys of the rear cover drive cable are mounted forwardly of the front wall of the rear truck. The support tube for the rear cover drive device is contained between the side walls of the rear container.
