Abstract: This invention relates to a hybrid nonisocyanate polyurethane network polymer formed by cross-linking at least one cyclocarbonate oligomer and at least one amine oligomer. The cyclocarbonate oligomer contains a plurality of terminal cyclocarbonate groups. At least one cyclocarbonate oligomer further comprises from about 4 % to about 12 % by weight of terminal epoxy groups. Because at least one cyclocarbonate oligomer contains both cyclocarbonate and epoxy reactive groups, the network formed therefrom is referred to as a hybrid nonisocyanate polyurethane network. The cyclocarbonate oligomer or oligomers have an average functionality towards primary amines of from about 2.0 to about 5.44. The amine oligomer comprises at least one primary amine-terminated oligomer terminated with primary amine groups and has an average functionality towards cyclocarbonate groups of from about 3.0 to about 3.8. The amine oligomer is present in an amount from about 0.93 to about 0.99 of the amount of the amine oligomer that would be required to achieve a stoichiometric ratio between the primary amine groups of the amine oligomer and the cyclocarbonate groups of the cyclocarbonate oligomer. The hybrid nonisocyanate polyurethane network polymer formed has a gel fraction of not less than about 0.96 by weight. This invention also relates to methods of making hybrid nonisocyanate polyurethane networks and their use as a composite matrix material.

Title: Apparatus and method for atmospheric pressure 3-dimensional ion trapping
Inventor: PURVES RANDY W
IPC: G01N27/64
Filed: 1999-08-05
Abstract: The present invention provides an apparatus for selectively transmitting ions and trapping the ions within a defined 3-dimensional space at atmospheric pressure. The invention is based on the ion focussing principles of high field asymmetric waveform ion mobility spectrometry in which an analyzer region is defined by a space between first and second spaced apart electrodes, the analyzer region having a gas inlet and a gas outlet for providing a flow of gas through the analyzer region. Ions which are introduced into the analyzer region are carried by a gas flow towards a gas outlet. At least one of the electrodes has a curved surface terminus located near the gas outlet and the gas flow is adjusted so that ions are trapped in a defined 3-dimensional space located near the tip of the terminus. Trapping of ions in a defined 3-dimensional space allows a more concentrated flow of desired ions.

Abstract: A hand held musical instrument is capable of emitting sound through the combination of three elements: a hollow tube (1), a striking member, and a hinge (3) to secure the striking member to the tube. The hollow tube is constructed of an ergonomic shape that allows easy and fatigue-free grasping.  For low notes, the slots on the resonating end of the hollow tube are multiple-sized to eliminate buzzing. The clapper is attached to the hollow tube through a combination of a stainless steel axle (10), polymer bearings (11a, 11b) and adjustable tensioning screws (12a, 12b). This combination improves the durability of the instrument yet still allows the musician to adjust the strike fell. The invention also provides improvements in the clapper heads for both low note and middle and high note handchimes. For low notes, the clapper head is constructed of multiple layers that optimize sound quality. For middle or high notes, the rubber clapper head provides multiple settings which allows the musician to easily and precisely adjust the timbre setting.

Abstract: An improved musical instrument string combines the attributes of superior corrosion resistance, low stiffness, low tension at pitch, and long life during storage and end use. The potential for galvanic coupling between the winding and core of wound strings is minimized, or eliminated through the use of a cathodic core, which is preferably comprised of a titanium alloy; and metal windings of either titanium, nickel, a nickel alloy, or a surface modified copper alloy, where the preferred surface modifier is a compound from the azole family. The resultant strings are lower in stiffness, and impart a lower cumulative tension on stringed instruments when compared to conventional metallic strings. The ends of the strings, including both ends of the wound strings, as well as one end of the non-wound strings, are preferably encapsulated with polymeric sheathings to maintain winding tightness over time, to maintain tuning at pitch, to maintain sound quality over time, and to protect the instrument bridge from excessive wear during end use. Preferred polymeric sheathings, such as polyvinylidene chloride or nylon, are used outside the speaking length of the string, so as not to dampen or modulate the tonal characteristics of the string during its vibration.

Title: Bleed back control valve
Inventor: WILSON VICTOR
IPC: A61M25/16
Filed: 2000-03-09
Abstract: A bleed back control assembly and method for controlling blood loss during catherization procedures includes a side arm body connected at the proximal end to a seal body. The side arm body comprises one or more branches, each having a lumen, and a finger rest on the exterior of at least one branch. The seal body comprises a cap assembly and a seal assembly. The seal assembly comprises a clamp seal and a bleed back seal, both made of elastomer and held by a seal holder. The cap assembly comprises a threaded cap and a funnel cap.  The threaded cap is connected to the seal holder. Rotation of the threaded cap causes the clamp seal to open or close. The funnel cap comprises a dilator, and pressing the funnel cap causes the dilator to open an aperture in the bleed back control seal. A spring, wound around the dilator, returns the funnel cap to its original position, thus closing the bleed back seal. The bleed back seal self-sizes to devices introduced through its aperture.  Dilating the bleed back control seal also allows purging of gases or fluids.  The clamp seal can clamp a device introduced transluminally to maintain device position, and the clamp seal may also be closed to allow high pressure injections.
