US Patent:

58612300, Jan 19, 1999

Filed:

Apr 21, 1997

Appl. No.:

8/843817

Inventors:

Shawn P. Lambert - Marlborough MA
Xiaojia Z. Wang - Acton MA

Assignee:

Polaroid Corporation - Cambridge MA

International Classification:

C08L 108
C08L 7700

US Classification:

430202

Abstract:

There is described a novel process of polymerizing 4-vinyl pyridine monomer in an aqueous polymerization system which comprises preparing an aqueous solution of polyvinyl alcohol, and contacting said aqueous solution of a polyvinyl alcohol with less than about 10% by weight of 4-vinyl pyridine monomer and a water-soluble initiator capable of decomposing to give free radicals. The resultant dispersion of the novel polymerization process comprises a homogeneous, i. e. , weight average molecular weight and particle size, poly-4-vinylpyridine, with no appreciable residual 4-vinyl pyridine monomer. The resultant dispersion may be used to coat image- and ink-receiving layers of image-recording materials and ink jet recording sheets, respectively.

International Classification:

B41M 500

US Classification:

Abstract:

Systems/methods for intelligent commissioning of an HVAC system provide a control node and at least a first network node coupled to communicate with the control node, the first network node configured to retrieve via a user interface objects configured at the control node, configure at least a second network node using the retrieved objects, and report the configuration of the second network node at the control node. A user interface of a first network node can access the objects at the control node. The first network node can apply the accessed objects to configure a second network node using a commissioning tool. The commissioning tool can be activated specifically for certain authorized HVAC personas or roles. The first network node can report the configuring at the control node. The commissioning tool can be voice-enabled to allow a single user to configure the HVAC system via voice commands.
