Abstract: A polymer scale preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising (A) a pyrogallol-acetone resin, and (B) a water-soluble polymeric compound. When a coating compris-ing the polymer scale preventive agent is formed on inner wall surfaces of a polymerization vessel and the polymerization is carried out by use of the vessel, deposition of polymer scale can be effectively prevented not only in the areas in the liquid phase inside the ves-sel but also in the vicinity of the interface between the gas phase and the liquid phase in the vessel. The polymeric product thus obtained can then be processed into sheets or other formed products which have few fish eyes and low initial coloration.

Patent CA-2109602-C (CA)
Inventor: WINTER GREGORY P
IPC: A61K39/395
Filed: 1992-05-15
Granted: 2002-10-01
Abstract: The invention provides methods and kits for producing specific binding pairs (sbp) members. Populations of polypeptide chain components of sbp members are combined to form libraries of sbps displayed by secreted replicable genetic display pack-ages (rgdp). At least one of the polypeptide chains is expressed as a fusion with a component of an rgdp which thereby displays that polypeptide chain at the surface of rgdp. At least one population of polypeptide chains is expressed from nucleic acid which is capable of being packaged using a component of an rgdp, whereby the genetic material of rgdps produced encodes a polypep-tide chain. The methods enable production of libraries of multimeric sbp members from a very large number of possible combina-tions. In one embodiment of the invention a method emplays "chain shuffling"  in the production of sbp members of desired spe-cificity for a counterpart sbp member. Selection procedures are also described.

Title: Conversion of doped polycrystalline material to single crystal material
Inventor: SCOTT CURTIS EDWARD
IPC: C30B29/20
Filed: 1995-01-26
Granted: 2006-04-04
Abstract: A solid state method of converting a polycrystalline ceramic body to a single crystal body includes the steps of doping the polycrystalline ceramic material with a conversion-enhancing dopant and then heating the polycrystalline body at a selected temperature for a selected time sufficient to convert the polycrystalline body to a single crystal. The selected temperature is less than the melting temperature of the polycrystalline material and greater than about one-half the melting temperature of the material. In the conversion of polycrystalline alumina to single crystal alumina (sapphire), examples of conversion-enhancing dopants include cations having a +3 valence, such as chromium, gallium, and titanium. The polycrystalline body further can be inhomogeneously doped to form a first portion of the polycrystalline body that is doped to the selected level of the conversion-enhancing dopant and a second portion that is not doped such that heating the doped polycrystalline body causes conversion of first portion to a single crystal structure and the second portion retains a polycrystalline structure.

Abstract: Admission device for admitting data cells to a transmission medium. The VC code of an arriving data cell is read out. A count value, which is a measure for the load of data cells with that VC code, is compared with a threshold, after which an admission code is issued, the value of which depends on the result of the comparison.      There is not used a single, but a plural threshold.

Abstract: A smart fastener having corrosion detection features. Within the fastener is a corrosion detecting array that receives an electrolyt e that corrodes sacrificial materials formed on electrodes of the corrosion detecting array. The materials are the same as those mater ials which are secured, fastened, or attached by the fastener. There is parallel corrosion of the sacrificial materials and the attached materi als since the electrolyte which is channeled via capillary tubes into the corrosion detecting array is the same electrolyte that is in the environ ment of the fastened materials. Other electrodes sense various properties of the electrolyte. Information sensed by the corrosion sensing electr odes of the array is in the form of very small electrical signals which are amplified and stored in an analog storage memory. A clock and ad dressing device time stamps and address the signals. An interface circuit enables a user to electronically access corrosion and related signa ls without removing or in any way dismantling the fastener.
