Abstract:
A method of modifying a chemical interaction between a functional group of an immobilized amine in a solid sorbent composition and a compound that chemically interacts with the functional group to reduce the heat required to desorb the compound from the solid sorbent. A method of inhibiting degradation of an immobilized amine in an immobilized amine solid sorbent. Compositions and methods of use of a low-cost regenerable immobilized amine solid sorbent resistant to degradation.
Abstract:
Methods and devices for effectively treating aphthous ulcers are disclosed. The invention employs the removal of the plaque layer of the aphthous ulcer to accelerate healing. Before the plaque layer is removed, the ulcer may be initially anesthetized, by rubbing with an appropriate material and/or compound. Subsequently, an appropriate medicament may be applied to accelerate healing, if desired. The invention teaches the structure and use of applicator/dispenser system employing easily crushable ampoules, containing an aesthetic, and other appropriate medicaments. The invention further teaches the application of slippery surfaces to teeth, teeth appliances, and oral cavity surfaces to inhibit the generation of aphthous ulcers, and to speed their healing. The application, in the form a gel or film, may include a sustained release medicament. Finally, the invention contemplates the use of replaceable and disposable tips for power toothbrushes and the like to aid the treatment of the aphthous ulcers, and the use of dendrimer technology to provide sustained and concentrated local drug action.
Abstract:
A gas detector utilizing tunnel junction geometry is disclosed. The gas detector comprises a first electrically conductive material layer, an electrically nonconductive material layer disposed on the first electrically conductive material layer, a second electrically conductive material layer disposed on the electrically nonconductive material layer, a gas source (34) in fluid communication with the second electrically conductive material layer; and a power source in electrical communication with the first and second electrically conductive material layers. A method of detecting a gas utilizing the detector of the present invention is also disclosed. A method of making a gas detector is likewise disclosed.
Abstract:
A poly(cyclosiloxane) is synthesized by oxidation with water in the presence of a Pt catalyst, followed immediately by polycondensation of the Si-OH groups to form Si-O-Si linkages. Thus, pentamethylcyclopentasiloxane can be polymerized into poly(pentamethycyclopentasiloxane).
Abstract:
A method for removing a liquid from a gas, comprises passing the gas and the liquid through a network of fibers containing at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber, thereby permitting droplets of the liquid to be captured by the at least one fiber, and wherein the temperature gradient causes migration of the droplets. A method of preventing the fouling of a coalescence filter is also disclosed. The method comprises inducing a temperature gradient along at least a portion of a length of at least one fiber within the filter, wherein the temperature gradient causes migration of liquid droplets captured by the fiber. A coalescence filter medium comprising at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber is also provided.
Abstract:
Various embodiments of aircraft brake assembly structures are provided for achieving noise reduction during braking activity. In certain embodiments of the invention, the actual application of force to the pressure plate is regulated such that a different number of actuator pistons are used during low-energy stops than during high- energy stops. In other embodiments of the invention, the pressure plate (32) or endplate (40) is augmented as to surface area in some instances and as to a taper angle in others, again to achieve a desired increase in effective pressure application during low-energy stops. In other embodiments of the invention, the stator and/or rotor disks are characterized by slots to break up the propagation of noise waves.
Abstract:
A shape memory composition includes a high temperature ionomer having a glass transition temperature or a melting temperature of 100°C or greater and a modulus at room temperature of 1 x 10 8 Pa or greater, the high temperature ionomer including a polymer with ionic units either within the backbone of the polymer or pendant to the backbone or both. The shape memory composition includes crystalline or glassy domains of a low molecular weight non-polymeric compound dispersed in the high temperature ionomer and interacting the ionic units of the high temperature ionomer to form a secondary network characterized by being a reversible network in that it is compromised by the heating of the low molecular weight non-polymeric compound to change out of its crystalline or glassy phase.
Abstract:
Personal dispensers include collapsible containers that are associated with pump mechanisms for dispensing fluid from within the collapsible containers. The pump mechanisms are preferable selectively operable to dispense a unit dose of fluid. The collapsible containers are sealed such that they lose volume as fluid is dispensed. Clips and housing members for holding and wearing the personal dispensers are also provided.
Abstract:
Dispensing systems are disclosed which utilize electronically powered key devices and/or identification codes associated with a refill container to preclude the need for mechanical keys. One embodiment of the device utilizes a matching code stored in a radio frequency identification tag or bar code associated with a fluid refill container and an identification code associated with the dispenser housing. Matching of the codes by a controller allows for continued use of the dispenser via some type of operational mechanism. Another embodiment employs a key which carries the matching code. Yet another embodiment employs a blocking mechanism to prevent use of a dispenser's push bar if a key and dispenser housing do not have matching codes. And yet another embodiment requires the use of a key that has a matching code that matches the dispenser's identification code to permit initial access to the dispenser housing.
Abstract:
A container used in connection with a dispenser, the container having one or more projections extending outwardly therefrom and engageable with the interior of the dispenser to secure the container in the dispenser.
