Title: Polymer composition for curing novolac resins
Inventor: WAITKUS PHILLIP A
IPC: C09J161/34
Filed: 2000-02-21
Abstract: A polymer composition that can be used to cure a novolac resin at a lower temperature than conventional novolac curing agents and with reduced emission of volatile compounds is disclosed. The novolac curing agent polymer composition is prepared by mixing and reacting in aqueous solution a phenolic monomer and an aldehyde in the presence of a basic catalyst to form an intermediate resin, and reacting the intermediate resin with an amine to form the polymer composition.  The aldehyde to phenolic monomer molar ratio in the reaction should be at least about 1.0:1, and preferably is at least about 2.0:1. The preferred amine is hexamethylenetetramine, and it is preferred that the hexamethylenetetramine to phenolic monomer molar ratio is at least about 0.12:1. In a preferred version, the aldehyde is formaldehyde, and the phenolic monomer is selected from the group consisting of phenol, substituted phenols, and mixtures thereof, with phenol itself being the most preferred phenolic monomer. The polymer is particularly advantageous in that the reaction temperature is lowered compared to other conventional curing agents, the unreacted phenolic monomer in the polymer composition may be adjusted to levels less than about 0.5 weight percent, and the unreacted aldehyde in the polymer composition may be adjusted to levels less than about 0.1 weight percent. As a result, the polymer releases minimal volatile compounds when used to cure novolac resins, and unlike conventional resole curing agents, has an indefinite shelf life in both the pure form and when blended with a novolac resins.

Abstract: Glide strips for wet shave razors in which the glide strips comprise a mixture of polyurethane and polyvinylpyrrolidone in a ratio of less than 3:1.  Preferably, the ratio of PVP/PUR is in the range of 3.0 -1.0:1. Most preferably, the ratio of PVP/PUR is in the range of 2.5 - 1.5:1. Glide strips having a ratio within this range provide the benefit of allowing an additive, such as aloe or vitamin E  acetate, to be incorporated within the strip in a manner so that it will be capable of depositing the material from the strip on the user's skin during usage. This will provide the benefit to the user of applying a material directly to the skin to enhance the shaving experience. A further embodiment provides a glide strip having a PVP/PUR blend of a certain color and ratio, which ratio will allow the PVP/PUR blend to erode as the razor is used. Upon the erosion of the PVP/PUR blend, the underlying material, of a different color than the PVP/PUR, will be exposed and provide an indication to the user that the razor should be replaced.

Abstract: A plug-type aircraft door is operated by two power assist door operating mechanisms or drives and a door operating handle that is also an electric switch which provides input signals to an electronic door control unit. Each door operating drive has its own electric motor connected to a control output of the electronic door control unit to receive motor control signals in response to the input signals from the door handle and switch.      The door handle and switch form a unit which is so constructed that manual operation of the door handle, when the door is closed, first mechanically releases a door locking safety.   Thereafter the switch causes the energizing of one electric motor for unlatching and lifting the door, and then causes the energizing of another electric motor for swinging the door open.      These controls are performed by the control unit in response to respective door handle switch positions. When the door is open and the door handle is operated in the opposite direction, the sequence is reversed, whereby the door is first closed, then lowered and latched and then locked by the door safety.

Abstract: A method and apparatus are disclosed for analyzing the aggregate content of asphalt-aggregate compositions. The method includes placing a preheated, preweighed container carrying a sample of an asphalt-aggregate composition into a preheated furnace with the preheated furnace being warmer than the preheated sample, continuing to heat the furnace while drawing air through the furnace at a rate that avoids impeding the heating of the furnace or the sample until the sample in the container reaches its combustion temperature and the combustion of the sample becomes exothermic, initiating a second draw of air around rather than through the furnace to moderate the exterior temperature of the furnace, accelerating the draw through the furnace to increase the rate of combustion of the exothermic reaction, and reweighing the container and sample after combustion is complete. The apparatus includes a furnace, a housing around the furnace, a furnace exhaust in communication with the furnace, a housing exhaust in communication with the housing, means for drawing an airflow through the furnace and into the furnace exhaust, means for drawing a separate airflow through the housing and into the housing exhaust, and a junction between the exhausts that forms a common exhaust from the housing and the furnace.
