摘要:
Apparatus and methods for deodorizing and/or freshening the air are disclosed. In one non-limiting embodiment, the apparatus includes one or more passive members and an air moving member. The passive member can be detachable from the air moving member and used separately as a passive filter member, if it contains a deodorizing substance, or as a passive emitting member, if it contains a substance to be emitted into the air. Numerous combinations of passive filter members and passive emitting members can be used with the air moving member, or as stand-alone members in the described methods. In other non-limiting embodiments, devices can be provided that both deodorize and emit substances into the air. Kits are also provided. The substances to be emitted may be arranged in various ways to improve the amount of exposed surface area of the substance to be emitted. Intensity controlling mechanisms are also provided.

A combination speed limiter and transmission interlock system for an engine-transmission power train that includes an internal combustion engine and a transmission, the power train of the type used to power outboard engines and the like. The system utilizes fewer connections, is less expensive, is expected to be more reliable, utilizes a single housing, is easier to manufacture, and uses fewer components than a power train that utilizes separate speed limiter and transmission interlock modules.

This invention pertains to a method of modifying or refining a surface of a wafer suited for semiconductor fabrication. This method may be used to modify a wafer having an unmodified, exposed surface comprised of a layer of a second material deployed over at least one discrete feature of a first material attached to the wafer. A first step of this method comprises contacting and relatively moving the exposed surface of the wafer with respect to an abrasive article, wherein the abrasive article comprises an exposed surface of a plurality of three-dimensional abrasive composites comprising a plurality of abrasive particles fixed and dispersed in a binder and maintaining contact to effect removal of the second material. In a second step, the contact and relative motion are continued until an exposed surface of the wafer has at least one area of exposed first material and at least one area of exposed second material.

The preparation, structure, and properties of solid inorganic materials containing cobalt, boron, oxygen and, optionally, aluminum, is described. Also described is the use of such materials in catalytic compositions for the conversion of organic compounds. In particular, the new material Co(BO.sub.2)OH is described as well as the use of such material in various catalyzed processes including oxidation of organic compound processes. A particularly useful process is a heterogeneous catalyzed partial oxidation of an alkylaromatic followed by complete oxidation to an aromatic polycarboxlic acid in a water phase.

Methods are provided to make acid functional fluoropolymers by: a) dehydrofluorinating a starting fluoropolymer with a dehydrofluorinating agent to form an unsaturated fluoropolymer; b) adding an acidifiable nucleophilic functionalizing agent to a double bond of the unsaturated fluoropolymer; and c) acidifying the added acidifiable function. Acid functional fluoropolymers and ion conducting membranes thereof are also provided, including acid functional fluoropolymer having pendent groups according to the formula: —X—Ar—An, wherein X is selected from O, S or NR, where R is selected from H and C1-C30 alkyl or aryl, which are optionally substituted, wherein Ar is a C6-C30 aromatic group, which is optionally substituted, wherein A is an acidic function or salt thereof, wherein a can be independently chosen to be 1, 2 or 3.

A process for preparing thrombin which comprises treating a mixture comprising prothrombin, factor Xa, factor Va, and phospholipids with calcium ions, at a pH of 6.0-7.0 is provided. In particular the pH of 6.0-7.0 may be generated by the addition of the calcium ions or by buffering the preparation to a pH of 6.0-7.0. Thrombin preparations so produced may be subjected to further purification and are particularly stable even when substantially free of exogenous stabilizing agents such as proteins, sugars, polyol and mixtures thereof, and may be subject to freeze-drying and a virus inactivation by heat treatment.
