Granted: 2004-12-07
Abstract: The four metal panel portions of an air conditioning unit roof curb have spaced sets of inwardly projecting lanced portions positioned adjacent their ends and defining tab-receiving slots. With the panel portions in a rectangular assembly orientation, specially designed drive cleats are used to lock the contiguous ends of the panel portions together at the corners of the curb. Each cleat has spaced pairs of tabs which, when the cleat is downwardly driven into place on a corner section of the curb, sequentially enter vertically successive pairs of slots in the contiguous panel end portions at the corner. In this manner, only one tab pair and one slot pair need to be aligned with one another before the cleat is driven into place to lock the two contiguous panel end portions to one another, the initial tab pair/slot pair alignment serving to automatically align the successive tab and slot pairs as the cleat is driven home. A pair of the tabs on each drive cleat have dimples thereon which function as detent structures that releasably lock the cleat tabs in their panel slots and thereby releasably retain the drive cleat in place on the assembled roof curb. In an alternate embodiment of the drive cleats, side halves thereof are formed integrally with ends of the panel portions, with the tabs of the integrally formed cleat halves being sequentially insertable into the tab-receiving lance slots of adjacent panel end portions.

Title: Cardiac tissue ablation device and method of use
Inventor: LESH MICHAEL D
IPC: A61B18/14
Filed: 1998-05-11
Granted: 2006-07-11
Abstract: A tissue ablation device creates long linear lesions along a body space wall of an animal, and primarily between adjacent pulmonary vein ostia in a left atrial wall. An ablation element includes first and second ends that are bordered by first and second anchors. The anchors are adapted to secure the ablation element ends at predetermined first and second locations along the body space wall such that the ablation element is adapted to ablate an elongate region of tissue between those locations. The anchors may be guidewire tracking members, each including a bore adapted to receive and track over a guidewire, and may anchor within adjacent pulmonary vein ostia when the engaged guidewires are positioned within the respective veins. Stop members may be provided on the guidewires and may be adapted for positioning the relative anchors or for forcing the anchors to fit snugly within the vein ostia. A conduit passageway through the catheter houses a stiffening stylet which may be advanced into the region of the ablation element in order to impart a shape to that element to conform it to a predetermined region of anatomy, or to stiffen the underlying catheter in order to advance the assembly into remote anatomy.

Title: Method for preparing melamine
Inventor: TJIOE TJAY TJIEN
IPC: C07D251/60
Filed: 1998-05-15
Granted: 2008-07-29
Abstract: Method for preparing melamine from urea via a high-pressure process in which solid melamine product is obtained directly from the melamine melt by transferring the melamine melt into a product cooling unit where it is cooled with ammonia. The melamine melt from the melamine reactor has a temperature between the melting point of melamine and 450 °C and is sprayed, via spraying means, into a product cooling vessel containing an ammonia environment with an increased pressure, where the melamine melt solidifies to form melamine powder. The melamine powder, having a temperature of between 200 °C and the solidification point of melamine, is maintained under an increased ammonia pressure for a contact time of between 6 seconds and 5 hours at a pressure. During this contact time, the powder melamine product may be maintained in the product cooling vessel, or a series of vessels, at a virtually constant temperature or may be cooled further to a temperature above 200 °C.

Title: Wristwatch with capacitive coupling
Inventor: BARRAS DAVID
IPC: G04G99/00
Filed: 1999-12-14
Granted: 2010-02-16
Abstract: The present invention concerns a wristwatch (30) including a case (32) provided with a first electric conductor (50) and an electric circuit (36) connected to said first electric conductor, and a wristband (34) including a second electric conductor (42). This wristwatch is characterised in that the first and second conductors are arranged to form an electric connection without any mechanical contact and, more precisely, by capacitive coupling. One advantage of such an arrangement of the wristwatch is that it achieves an electric connection without mechanical coupling, i.e. an electric connection which does not require any additional external material arrangement other than the conventional articulation between the wristband and the case.

Abstract: A venetian type blind has a length adjustable bottomrail to fit windows of different lengths. A cord stop device is attached to each lift cord and each cord stop device is shaped such that when the device is attached to a lift cord the cord stop device can be removably connected to a retainer in the bottomrail and when not connected to the retainer will orient itself to be self guiding through route holes in selected slats when the lift cord is pulled through the selected slats. The blind is shortened by releasing each cord stop device from its retainer and passing the device and attached lift cord from the bottomrail through the slats to be removed to the slat at the desired length.  The excess slats are removed. Then the ladders are detached from the bottomrail, shortened and reattached to the bottomrail. The cord stop devices are then reconnected to their respective retainers in the bottomrail to complete the shortening process.

Abstract: An Asynchronous Transfer Mode (ATM)-based distributed virtual tandem switchi ng system is provided in which a network of ATM-based devices is combined to create a distributed virtual tandem switch. The system includes an ATM switching network that dynamically sets up individual switched virtual connections. The system also includes a trunk interworking function (T-IWF) device and a centralized control and signaling interworking function (CS-IWF ) device. The trunk interworking function device converts end office voice trunks from TDM channels to ATM cells by employing a structured circuit emulation service. The centralized control and signaling interworking functi on device performs call control functions and interfaces narrowband signaling a nd broadband signaling for call processing and control within the ATM switching network. Consequently, the ATM based distributed virtual tandem switching system replaces a standard tandem switch in the PSTN.
