  • Patent number: 6000192
    Abstract: The method of manufacturing standard size dwellings using a movable manufacturing facility brings standard size home building comprehensively within a controlled factory environment. The main structure of the movable manufacturing facility is sufficiently tall to allow assembly and movement of standard size homes within. Multiple independent production lines are established to each produce portions of the dwelling in the form of subassemblies. Finishes, cabinets, appliances, roofs, paint, etc. are installed in the partially completed dwellings prior to houses leaving the production floor. The movable manufacturing facility allows a standard size home under construction to be advanced via a transport element from one production line to the next until complete. The completed homes are subsequently transported on the transport element over a controlled access roadway to individual sites with pre-constructed foundations specifically designed to accept these standard size dwellings.

  • Patent number: 5664190
    Abstract: The invention provides a system and method which enable programs written in procedural languages to respond reactively to messages from event driven interfaces. An interface is provided between programs or window procedures written in procedural languages and the standard message queues of a standard event driven user interface, operating system and graphic engine. The interface pulls messages intended for the programs off of the queues and then forwards them to the appropriate program upon receipt of a call from the program.

  • Patent number: 5585423
    Abstract: Polymers of (N-lower alkyl)dimethylglutarimide or (N-hydrogen)dimethylglutarimide are resistant to surface crazing, molecular weight degradation and yellowing on exposure to ultraviolet light, by inclusion of a hindered amine stabilizer.

  • Patent number: 5434197
    Abstract: Decreasing the transmittal of near infra-red radiation through transparent glassy polymers, such as methacrylic ester polymers or those containing a high proportion of N-methyl dimethylglutarimide units, by use of a blended absorber is extremely difficult to accomplish because of the thermal instability of such absorbers under conditions necessary to process the glassy polymer. Use of very low levels of a specific class of thermally stable additives produces a thermally stable polymer blend which may be converted into transparent sheet exhibiting lowered transmittal of near infra-red radiation and useful for many glazing applications.

  • Patent number: 5264483
    Abstract: Glutarimide polymers having an acid and anhydride content lower than the acid and/or anhydride content normally present in the glutarimide polymers. Blends of the reduced acid and anhydride glutarimide polymers with thermoplastic materials are disclosed. A process for altering the properties of imide polymers by reducing or substantially removing acid and anhydride levels normally present in the imide polymer is also disclosed.

  • Patent number: 5159058
    Abstract: Polyglutarimides exhibit improved optical properties, as well as lowered content of non-aqueous volatiles, when the molten polyglutarimide is mixed with water, methanol, ethanol, or mixtures thereof, and the water, methanol, ethanol, or mixtures thereof is removed prior to isolation and processing of the polyglutarimide.

  • Patent number: 4874824
    Abstract: Thermoplastic copolymers of glytaric anhydride and (meth)acrylic esters may be prepared free of acid groups by reacting a (meth)acrylic ester polymer with a secondary amine at elevated temperature, and subsequently removing volatile components from the polymer at elevated temperature and reduced pressure.

  • Patent number: 4146934
    Abstract: A fabric, annular band, used for trimming or finishing the terminal edges of a garment, which garment usually has raw outer edges. In many cases, such as waistbands on trousers or skirts, the waistband must be curved, or contoured to adequately complement the anatomical configuration of any wearer. Thus, in any normal person, the hip bones are not on the same level as the waist itself. Accordingly, a simple straight band will not be satisfactory. The art has met the problem by forming the band in multiple sections, interconnected by seams, each section assuming an angularity relative to an adjacent section, to form a composite curved structure. My band, on the contrary, is one-piece, effecting many economies, including eliminating the use of relatively skilled labor.
