摘要:
Percussive signal transmission tubes, of contrasting color, are joined along adjacent longitudinally extending portions by an adhesive bead of polymeric material. The tubes can be separated in the field and are provided on spools without any sheath. A small diameter (0.10 inch) tube can be used to reduce the size of the spool, or increase the length of tubing wound on the spool. An apparatus for assembling the product is also disclosed.

摘要:
A block molded from a polymeric material has a through passageway to contain a percussive shock wave. Angularly related channels communicate with the containment passageway for receiving arcuate segments of detonation cord. Alignment of a plurality of blocks provides a convenient packaging setup for the cord. A percussive signal traveling along the cord can be short-circuited in the packaging setup. A diode version of the block can react to the signal in a given direction of travel.

The book trimming apparatus includes guides which direct a collated and, optionally, bound book to a fore-edge trimming station. The book trimming apparatus further includes a transfer station and a side-edge trimming station. For both the fore-edge trimming station and the side-edge trimming station in each case the book is orientated so that the edge to be trimmed is arranged substantially parallel to the direction of motion of the book. The automated book trimming apparatus is particularly suited for use in combination with collation and binding stations in in-line book manufacture.
摘要:
A device and method for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The single disc mechanical closure device is comprise of a distal and proximal anchor constrained by a closure line to facilitate mechanical closure by bringing the distal and proximal anchors into close proximity along the closure line.
摘要:
A method and system for limiting energy to a sensor and/or an environment in which the sensor is located. A high current sensor driver is powered through a resistance-capacitance (RC) circuit. In a failure mode, the RC circuit constrains output of a sensor driver to the sensor in order to limit average current applied to the sensor. In one embodiment, the capacitor is chosen so that it can provide adequate current to the sensor driver for a short period of time. The value of the resistor may be chosen to ensure that under short circuit conditions direct current (DC) is limited to a safe value. The combined values of the resistor and capacitor may be adjusted such that the capacitor can charge to a prescribed level during the interval between active pulses.

A tire in which a tire manufacturer has determined the tractive capacity at numerous levels of tread wear, the tire having at least one visual warning indicator located at a tread depth corresponding to a percentage loss of tractive capacity. Also, a method of making the tire and a method improving traffic safety through use of such a tire combined with educating the consumer as to proper use of the tire.

Binding apparatus and a related process are particularly suited for binding digitally-printed sheets into booklets. The apparatus is adapted to fold individual sheets and then to apply adhesive to the fold line before gathering the sheets in a collator ready for binding. The collator includes either a rotatable or retractable finger that is moveable to temporarily inhibit registration of a first sheet of a new stack on a stacking area, as a previous stack is transported away.
