Title: Process for applying a foamed coating to a medical adhesive tape
Inventor: RIEDEL JOHN E
IPC: C09J7/21
Filed: 1994-11-04
Abstract: This invention generally relates to a process for applying a foamed coating to a web and particularly relates to a process for applying a foamed release coating to a porous, pressure sensitive adhesive medical tape backing. The disclosed process may be used, for example, to apply a thin, uniform release coating to a porous pressure sensitive tape and includes the steps of i) forming a porous tape backing having at least one surface from polymeric fibers, ii) forming a foam of a release coating, wherein the foam is prepared by mixing water, the desired coating, and a surfactant to give a foam composition that collapses immediately when the foam composition is applied to the porous tape backing, iii) applying the foam to at least one surface of the porous tape backing to give a coated tape backing, and iv) coating the tape backing with a pressure sensitive adhesive before or after the relase coating is applied. A related process to apply a foamed latex adhesive to an elastomeric tape backing is also disclosed.

Title: Method for inhibiting hydrate formation
Inventor: COLLE KARLA S
IPC: E21B43/12
Filed: 1996-06-06
Abstract: A method for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents involves treating the fluid with an inhibitor comprising a substantially water soluble polymer or copolymer selected from the group consisting of the following N,N-diallylamides:       where R is a branched, normal or cyclic hydrocarbon group having one to ten carbon atoms, and x is an average number of monomeric units for producing an average molecular weight for the polymer between about 1,000 and about 6,000,000. The rate of nucleation, growth, and/or agglomeration of gas hydrate crystals in a petroleum fluid stream is reduced using the N,N-diallylamide inhibitor, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.

Title: Process for the preparation of a sulfate- and hydroxide-based ferric compound
Inventor: JAFVERSTROEM STEFAN
IPC: C01G49/10
Filed: 1994-12-29
Abstract: The invention relates to a process for the preparation of a pure and solid, sulfate- and hydroxide-based ferric compound such as ferric hydroxysulfate or sodium jarosite, the process comprising the following procedures: a) a sulfate- and/or chloride-based ferric salt is prepared, b)  an acidic aqueous solution is prepared which comprises either sulfate ions and ferric ions or sulfate, chloride and ferric ions, c) the acidic aqueous solution is maintained for 2-12 h at a temperature  of  60-220 °C  for  the production of  a  solid, sulfate- and hydroxide-based ferric compound, such as ferric hydroxysulfate or sodium jarosite, by hydrolysis, and d) the pure and solid sulfate- and hydroxide-based ferric com-pound, such as ferric hydroxysulfate or sodium jarosite, is separated from the acidic aqueous solution. The processes for the preparation of ferric hydroxysulfate and sodium jarosite differ substantially only in that in the pre-paration of sodium jarosite an acid aqueous solution is pre-pared which, in addition to the either sulfate and ferric ions or sulfate, chloride and ferric ions, also contains a water-soluble sodium compound,  in which case sodium jarosite is formed instead of ferric hydroxysulfate in the hydrolysis of point c) of the process.

Inventor: HAYASHI KEIICHI
IPC: H04W4/00
Filed: 1996-12-13
Abstract: Data communications are carried out between port-able information terminals through infrared radiation with an energy source which may be either a battery in each of the portable information terminals or an exter-nal power supply therefor, at a data transmission rate which is relatively low when the portable information terminal is operated by the battery.  If the power source is the incased battery, the data transmission rate is switched to a low rate, data to be transmitted are compressed, and the respective numbers of bits "0" and "1" contained in the compressed data are compared with each other.  If the number of bits which require a greater amount of electric energy for transmission is greater than the other number of bits, then the value of bits is inverted.  Data indicative of the low data transmission rate, the compression of the data, and whether the value of bits has been inverted or not are coded into header data which are added to the com-pressed data for transmission.  The data transmission rate is adjusted, the compressed data are expanded, and the inverted value of bits is inverted back by a con-troller in response to the header data at the receiver side.
