Title: Method for manufacturing poly(hexamethylene adipamide) from monomethyladipate and hexamethylenediamine
Inventor: MARKS DAVID NEIL
IPC: C08G69/04
Filed: 1998-12-17
Granted: 2007-01-09
Abstract: An improved method for manufacturing poly(hexamethylene adipamide), i.e. nyl on 6,6, by resting monomethyl adipate with hexamethylenediamine in an approximately equimolar ratio in the presence of water at a temperature of 100 to 165 .degree.C while simultaneous distilling off of a stoichiometric amount of methanol. The resulting aqueous intermediate product is then heated to 200 to 260 .degree.C while distilling off substantially all water at a pressure of 1.50 to 250 psig (1. 03 .times. 10 6 to 1.72 .times. 10 6 Pa) followed by reducing the pressure to atmospheric pressure and increasing the temperature to 270 to 280 .degree.C to polycondense the distillate residue. Such a process is useful in producing high purity commercial grade poly(hexamethylene adipamide) that advantageously avoids problems caused by N-methylation of the polyamide.

Abstract: A wear protection system (14) is disclosed for protecting a parent member (12) of an earthworking machine, such as a bed of an off-highway truck for instance. The protection system (14) includes a replaceable wear member (10), which is detachably mounted to a mounting base (16) by a retainer (18). The wear member (10) is provided with a skeletal frame (30) with an enlarged window-like opening (32) and outstretched leg portion (44) to reduce the weight of the wear member (10). The pockets (94, 96) formed by the window like opening (32) and in the spaces between adjoining wear members (10) fill with material so as to insulate the parent member (12) of the truck bed from frictional wear due to material sliding over the bed when dumping material therefrom.

Abstract: A terminal-to-terminal communication connection control method that can be applied to multimedia communication in which a connection server and a relay connection server are installed in an IP transfer network. A telephone set and a terminal such as an IP terminal and a video terminal transport an initial address message, an address completion message, a call pass message, an answer message, a release message, a release completion message, which can be made in 1-to-1 correspondence with line connection control messages of a common line signal system. Furthermore, while an address administration table is set to a network node apparatus of an IP transfer network, means for registering addresses of the terminals into this address administration table is employed, so that an IP packet communication by a multicast can be realized with improved information security performance.

Abstract: A method for determining platelet activation by utilizing numeric counts of platelets before a sample of platelets has been activated and after the activatable platelets are activated with a platelet activation agonist and using the difference between such counts as an indication of the platelet activity of the sample. There is also disclosed a method for using the electronic impedance cell counting technique for determining platelet activation wherein EDTA is used as a preservative by counting the platelets in an EDTA preserved sample using an electronic impedance cell counting technique and subtracting from that number the number of platelets remaining after the activatable platelets in a second sample have been activated with a platelet agonist in the absence of EDTA and using that difference as a measure of platelet activity.

Granted: 2004-04-13
Abstract: A carbon dioxide precooling system (1), linked with a carbon dioxide source (2) and with a carbonator (3), for aiding in carbonated water formation includes a carbon dioxide line (2') linked with the carbon dioxide source at an inlet and with the carbonator at an outlet. As such, carbon dioxide travels from the carbon dioxide source, across the carbon dioxide line, and to the carbonator.

Granted: 2011-03-29
Abstract: A water heater having a water tank and multiple electric resistance heating elements extending into the water tank for heating water in the tank. The water heater includes a proportional band temperature controller for conducting electric power to the electric resistance heating elements in bursts. Each burst of electric power is followed by a period during which the temperature controller does not conduct power to the electric resistance heating element. In one embodiment, each burst of electrical power lasts for about 95% or less of a cycle comprised of one burst of electric power followed by the period during which the temperature controller does not conduct electric power. Further, activation of the heating elements by the controller is carried out in a sequential or other timed or controlled fashion to permit uniform heating of the water in the tank.

Title: Stent with angulated struts
Inventor: FISCHELL TIM A
IPC: A61F2/90
Filed: 2002-09-11
Granted: 2009-11-10
Abstract: The present invention uses sets of strut members where the most distal set of strut members is similar to that of most stents in that the plane of the distal set of strut members is perpendicular to the stent's longitudinal axis. The present invention has a multiplicity of circumferential sets of strut members, but only the distal set of strut members has its plane perpendicular to the stent's longitudinal axis. The more proximal sets of strut members are angulated, so that the plane of the most proximal set of strut members has a preset angle such as 30°, 45° or 60° relative to the stent's longitudinal axis. The stent could also be formed from or coated with a highly radiopaque material. Alternately, a radiopaque marker could be placed at the most proximal point of the angulated, side branch stent, for the stent has to be rotated by the clinician until the plane of the most proximal angulated set of strut members is situated to be approximately parallel to the plane of the ostium of the side branch. It is also envisioned to widen the diagonal sections of the most proximal circumferential set of strut members to increase their radiopacity as compared to the radiopacity of the more distal circumferential sets of strut members. This can assist the clinician who places the side branch stent to have it properly placed at the ostium of the side branch.

Abstract: La présente invention concerne un four combiné, à convection et à vapeur, qui comprend un pulvérisateur à trois étages, permettant de fragmenter l'eau d'alimentation, avant sa vaporisation. ce pulvérisateur comprend un ventilateur motorisé, qui présente une coupelle de pulvérisateur au niveau de son moyeu, tournant avec le ventilateur autour d'un axe de rotation. Cette coupelle de pulvérisateur présente des parois rectilignes ou concaves, qui définissent des poches à encoches longitudinales au niveau de leurs coins. Lorsque cette coupelle de pulvérisateur tourne, l'eau d'alimentation est apportée dans la coupelle, de façon à percuter les surfaces internes et à être cisaillée lorsqu'elle sort à travers les encoches, sous l'effet d'une force centrifuge qui dirige l'eau à travers les pales du ventilateur. L'eau d'alimentation est ainsi fragmentée par trois actions séparées, avant d'être vaporisée.

Abstract: A rotor of a crankshaft has protrusions . A timing sensor produces a rotation leading signal and a rotation trailing signal. A control unit measures a previous signal production interval and a present signal production interval based on the rotation signals, and determines that the rotor is in the forward rotation if an inequality of Tn/Tn-1 <= K holds alternately but consecutively by four times on the side of the rotation trailing signal. As a result, at the time of manufacturing the rotor, the degree of freedom of design in the positional relations of the protrusions can be enhanced to control the ignition timing precisely and stably.
