摘要:
A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.

A roller shade mounting system includes a pair of assemblies for limiting sagging in a roller shade tube. The assembly includes a single bearing supported by a shaft to position the bearing at a distance from an end of the tube. Alternatively, the assembly includes a bearing pair supported by a shaft to define spaced support points for applying a reaction moment the roller tube. The assembly further includes an attachment member secured to the shaft at a first end and to the structure at an opposite second end, either directly, or to a mounting bracket secured to the structure. The mounting assembly may further include a deflection adjustment member engaging the attachment member and a fixed support member to provide variable control of roller tube deflection.

A dimmer switch assembly consists of a conductive yoke which has two insulation housings connected thereto which carry respective subassemblies for the dimmer switch. The first insulation housing contains a rotatable push shaft. Shaft rotation rotates a resistor plate having a resistive pattern on its surface relative to fixed resistor contacts. A biasing spring biases the shaft to an outward position relative to the conductive yoke. A cavity in the first housing receives a main power semiconductor device of the dimmer switch. The power semiconductor device is thermally connected to the yoke through a thin electrically insulative tape and has an active, non-electrically isolated, heat sink. A biasing spring within the first housing presses the power semiconductor device toward mechanical engagement with the yoke. The first housing assembly is fastened to the yoke by conductive eyelets which are insulated from the power semiconductor by the first insulation housing. The second insulation housing is a switch housing which contains a rotatable indexing cam switch which rotates relative to two spring contacts disposed on opposite sides of the cam such that the rotation of the cam alternately connects and disconnects the contacts through a conductive spider on the cam. The cam is operated by depressing the main shaft relative to the yoke. Insulation keying structures automatically key the first and second housings relative to the yoke and to one another.

Import/export transactions whereby an item is to be transported from one country to another are automated. An invoice containing a list of one or more part numbers is entered in at a web site and loaded to a server containing a database. A database is of part numbers and their corresponding tariff classification numbers. The uploaded invoice will be compared to the database to output a data record whereby the one or more part numbers uploaded in the invoice now have tariff classification numbers and daily calculation associated therewith This data record can then be accessed over the Internet at another web site by a customs broker for use in transmitting a report to a customs entity.
摘要:
A vacuum insulated refrigerator cabinet comprises an evacuation system for evacuating an insulation space of the cabinet when pressure inside such space is higher than a predetermined value. It comprises a sensor device having an insulation reference element located on one side of said insulation space and temperature sensors for assessing the differences of temperature across the insulation space) and across the insulation reference element, such sensor device being suitable for providing the evacuation system with a signal related to the ratio of the above differences of temperature.

A roller shade mounting system provides a tube-in-tube arrangement for reducing sagging of a roller tube windingly supporting a shade fabric. The mounting system includes a mounting tube received within a roller tube, and first and second annular drive rings located on an outer surface of the mounting tube. The drive rings are secured to the mounting tube and the roller tube secured to the drive rings such that rotation of the mounting tube results in rotation of the roller tube. Each drive ring is located at a distance from an end of the roller tube for limiting sagging deflection of the roller tube. The tube-in-tube arrangement provided by the mounting system provides controlled deflection for the roller tube without necessitating undesirably large increase in the diameter of the roller tube, which could create an undesirable appearance in many roller shade installations.
