摘要:
In order to increase the endurance and lifetime of highly loaded components (6, 8, 12, 14, 24, 26, 34) of a steelworks, an electrolytically applied coating (38) is provided, having a ductile metallic base material (39), in particular nickel or a nickel alloy, with hard material particles (40), in particular boron carbide particles, incorporated in it. This measure achieves high resistance to corrosion, good thermal conductivity and at the same time high mechanical loadability.

A retractable awning cover for a slide out unit on a recreational vehicle, mobile home, travel trailer or the like includes a scissors arm support system that elevates a support bar running longitudinally of the vehicle to establish a gable shape for the awning cover when extended. The support bar is automatically lowered during retraction so as to be alignable with the scissors arms that support the support bar.

An apparatus for reducing modem command and status latency within a direct access arrangement (DAA) circuit is disclosed. The DAA circuit includes a serial audio interface for providing communications between the DAA circuit and the host computer system. The serial audio interface can operate under multiple serial communication interface standards, such as the AC '97 standard and the HD Audio standard. The DAA circuit also includes means for configuring the serial audio interface to transmit and receive modem samples at an audio sample rate higher than a modem sample rate of the modem samples and at a predetermined bit size that is wider than a bit size of the modem samples. The additional bits other than the modem samples are utilized to indicate command and status information associated with the DAA circuit or a telephone line such that modem command and status latency on the serial audio interface within the DAA circuit can be reduced.

An automatically extendible and retractable awning includes an awning sheet mounted along one edge to a support structure and at an opposite edge to a roll bar about which it can be selectively wrapped. Each end of the roll bar is supported by a scissors type support structure allowing the awning to be extended and retracted in a simple but effective manner while allowing considerable space for movement of individuals around the awning.
摘要:
A substantially planar insulating sheet of high temperature printed circuit board material (11) is used to form a leadframe strip (18, 19, 21) for a semiconductor package (20). The leadframe strip (18, 19, 21) includes a die attach opening (12) through the insulating sheet (11). A plurality of metallized areas (13, 22, 23) on the insulating sheet (11) form bonding pads (13) and package leads (22). Conductive holes (14) electrically connect the bonding pads (13) and the package leads (22).
摘要:
An apparatus for removing a cylindrical tubular elastomeric cover from and applying a cylindrical tubular elastomeric cover to a cylindrical top roll mandrel of a top roll. An attachment holder holds a selected cover removing or cover applying attachment. A cover applying attachment is held by the attachment holder for carrying a top roll cover to be applied to the top roll mandrel. A cover stripping attachment is provided for being held by the attachment holder and for stripping a cover from a top roll mandrel. A chuck is provided for holding a top roll mandrel with a cover to be removed by the cover stripping attachment, or a top roll mandrel without a cover for receiving a cover applied by the cover applying attachment. A piston and cylinder assembly moves the top roll mandrel reciprocally to and from the attachment holder and the cover applying attachment or the cover stripping attachment held by the attachment holder to thereby apply a cover to or remove the cover from the top roll mandrel.
摘要:
A process for the production of bags from thermoplastic synthetic resin sheeting with a bottom seam and/or a lateral seam fashioned as a cutoff weld seam obtained by severing tubular film sheets in the bottom zone, wherein there is produced by heat contact welding, at a station upstream of a transverse seam cutoff welding of the bottom seam or lateral seam, a wide flush weld seam over the entire width of the tubular film sheet and/or of the bag bottom to be produced, and subsequently the transverse cutoff weld seam is formed over the flush weld seam, extending within the flush weld seam.
