Abstract: A bag sealing system for securing one or more items in a closable bag comprises a moveable frame, a closable bag, a closing device and a driving device. The moveable frame can have an open configuration, intermediate configurations and a closed configuration. The closable bag has an open end and a closed end wherein the open end of the closable bag is coupled to the moveable frame. The closing device is provided for securely closing the open end of the bag via a securing element, and the driving device is coupled to the closing device to actuate the closing device to securely close the closable bag.

Abstract: A compression device for freeing a ring trapped on a digit includes a rigid outer body. The rigid outer body includes a digit cavity extending from a cavity opening at a body proximal end of the body towards a body distal end of the body, a fluid inlet, and a fluid flow path fluidly connecting the fluid inlet to one or more inflation chambers positioned in the digit cavity. The body proximal end includes an upper portion, a lower portion, and two laterally spaced-apart side portions. At least one side portion is distally recessed as compared to the upper and lower portions to accommodate an interdigital fold. At least one flexible bladder lines the digit cavity, each flexible bladder defining at least one wall of one of the one or more inflation chambers.

Abstract: A pneumatic tire for use on trucks, the tire comprising: a tread which includes a belt reinforcement structure, the belt structure including a pair of working belts, wherein the angle of the working belts range from about 16 degrees to about 30 degrees, wherein a low angle belt is positioned preferably between of the working belts, wherein the angle of the low angle belt is less than 5 degrees. The working belts are extensible, and preferably made of high elongation wire.

Abstract: A pneumatic tire is described which includes a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a pair of working belts, wherein the angle of the working belts range from about 15 degrees to about 30 degrees, wherein the belt structure further includes a zigzag belt structure located between the working belts. The zigzag belt structure is formed of at least two layers of cords interwoven together from a strip of rubber reinforced with one or more cords, wherein the strip forming the zigzag belt structure is layed up in a first zigzag winding extending from a first lateral belt edge to a second lateral belt edge in a zigzag wavelength having a first amplitude W1 followed by a second amplitude W2, and a second zigzag winding formed of a zigzag wavelength having a first amplitude W2 followed by a second amplitude W1.

Abstract: A pneumatic tire comprises a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a zigzag belt structure formed of at least two layers of cords interwoven together from a strip of rubber reinforced with one or more cords. The strip forming the zigzag belt structure is layed up in a winding pattern in accordance with the following formula: for i=1 through L, the ith winding pattern is: [WL-(i-1)Wi]×N for each drum revolution, wherein L is the number of different amplitudes used to define the zigzag cycle and L?2, and N is the number of zigzag cycles per drum revolution and N is either an integer ?1 or N=1/2n wherein n is an integer ?1.

Abstract: The present invention relates to an access unit for coupling a plurality of subscribers to a data communication network, and comprising an auto-configuration control unit adapted to learn, from first auto-configuration data issued by an auto-configuration server and transiting through said access unit towards a particular subscriber coupled to said access unit, a particular network address as being dynamically assigned to said particular subscriber.

Abstract: In access multiplexers (1) for multiplexing Internet Protocol packets to be exchanged between network devices (2) and subscriber devices (3-5), the Internet Protocol packets are encapsulated at each side of the access multiplexers (1). By providing the access multiplexers (1) with Internet Protocol routers (6-8) for routing the Internet Protocol packets via direction dependent routes, the access multiplexers (1) have become transparent for routing protocols at Internet Protocol level which use multicast Internet Protocol destination addresses or broadcast Internet Protocol destination addresses. Between the network devices (2) and the access multiplexers (1) Ethernet packets are exchanged via virtual local area network connections (21-23) and between the subscriber devices (3-5) and the access multiplexers (1) Asynchronous Transfer Mode packets are exchanged via permanent virtual connections (31-33).
