A director-controlled web server comprises a processing system, an interface, and a screen. Using the screen, the director selects a web site to provide content pages to participating browsers. The interface then receives refresh messages from the participating browsers and transfers the refresh messages to the processing system. The processing system generates responses with a refresh tag and the URL for the currently selected web site. The interface transfers the responses to the participating...

An electronically controlled electromechanical valve having at least three ports through which a fluid can flow and at least three different stable positions in which at least 2 ports are in fluid communication. The valve includes a stationary outer housing including at least three bores, a rotating inner section that rotates about an axis and includes bores defining, with the bores of the housing, the at least three ports of the valve, and an electrical actuating system controlled by an electro...

A torque-controlled rotational module is described. The torque-controlled rotational module has a fixing base, a rotational member, a spring member, and a torque adjusting ring. The fixing base further has a fixing wall and a cable hole therein for a cable to pass therethrough. The module further utilizes wear-resisting members configured on both sides of the rotational member, between the torque adjusting ring and the fixing base, to protect the torque adjusting ring and the fixing base from we...

A remote controlled latching system includes a latch device configured for mating engagement with a connection member to secure an attachment to a carrier; a latching cylinder coupled to the latch device, the latching cylinder having a latched position and an unlatched position; a valve assembly fluidly coupled to the latching cylinder, the valve assembly being configured to selectively drive the latching cylinder into the latched position and the unlatched position; a latching control switch op...

Hardware that improves the safety of operating sectional doors that use torsional coil springs to facilitate door movement. A rotor assembly with centrifugally activated throw-out latches is affixed to the rotating shaft that bears the torsional coil springs. When a spring breaks, the shaft rotates rapidly as cables supporting the door unwind. Rapid rotation causes centrifugal force to bias the latches to an outer position in which they strike a trigger plate, allowing a pawl to move into a posi...

A program-controlled unit has debug resources for monitoring the operations proceeding within the program-controlled unit. The program-controlled unit described is distinguished by the fact that the debug resources contain a CPU, and/or that a portion of the debug resources is provided for monitoring the operations proceeding within the remainder of the debug resources. Debug resources constructed in this way make it possible for errors occurring in program-controlled units to be localized and e...

A voltage-controlled current source (VCCS) is provided. The VCCS controls an output current according to a controlling voltage. The VCCS includes an operational amplifier (OP-amplifier), a transistor, a resistor and a current mirror. The present invention utilizes the characteristics of the OP-amplifier to compensate for the voltage difference between the gate and the source of the transistor so that the resulting terminal voltage on the resistor is equal to the input control voltage. Therefore,...

In the case of nested containers to be filled by a filling station, a gripping device grasps an entire row of empty containers and conveys it to a weighing station, where the containers are weighed. Following weighing, all containers of the row are simultaneously filled and then reweighed. The containers are then reinserted into the nest and sealed, without being refilled, which allows checking the operation of the filling station without wasting product.

A container having a controlled-opening lid includes a container body with an open end providing access to an interior space configured and dimensioned for receiving user-supplied contents, and a lid member configured and dimensioned to cover the open end of the container body when in a first position and permit access to the interior space when in a second position. A hinge is configured to move the lid member from the first position to the second position, the hinge including at least one damp...

A rotor controlled CVT including: input and output shafts (28,44), an elongated cam-shaped rotor (12) which is uniformly and linearly tapered over its length and is engaged for rotation with the input shaft, a plurality of cam follower units (54) which are located in structure about and are reciprocated by the rotor and include rollers (56) having treads which bear and rotate in circumferential paths on the rotor surface, angular velocity extraction devices (38) which are each engageable and par...
