Title: Tobacco filters and method of producing the same
Inventor: TSUGAYA HITOSHI
IPC: A24D3/14
Filed: 1994-07-12
Abstract: A filter rod is produced by adding a water-soluble polymer in the form of an aqueous solution or dispersion, or in a particulate form, to a tow of cellulose ester fiber, with the amount of any water used being controlled within 25 parts by weight relative to 100 parts by weight of the tow, and wrapping the treated tow in wrapping paper. The water contained in the filter rod is removed or the particulate water-soluble polymer is melted by heating to bond the fiber to provide a tobacco filter. The proportion of the water--soluble polymer is 0.5 to 30 parts by weight to 100 parts by weight of the tow. To reduce the amount of water relative to the tow, a hot-melt adhesive water- soluble polymer may be employed. As the amount of water added to the tow is thus decreased, the tow can be smoothly wrapped up even at a high speed so that filter productivity is improved. This tobacco filter is highly wet-disintegratable and, hence, contributes to mitigation of the environmental pollution.
Patent CA-2133132-A1 (CA)
Title: Technique for improving performance in an optical transmission system
Inventor: HOMSEY GLEN M
IPC: H04J14/06
Filed: 1994-09-28
Abstract: The effects of polarization dependent hole burning are reduced by simultaneouslylaunching a first optical signal carrying information and having a first characteristic wavelength and a second optical signal carrying different information and having a second characteristic wavelength, where the first and second optical signals have substantially orthogonal relative polarizations, into the same transmission path as a combined optical signal. The launched optical signals have equal optical power levels. Thus, the noise associated with one optical signal cannot be preferentially enhanced with respect to the information carried by the other optical signal. Furthermore, because the combined optical signal is created by coupling two highly-polarized signals, the poor noise and dispersion characteristics normally associated with non-polarized light sources are avoided. As a result, the effects of PDHB are minimized (FIG. 1)

Title: Process, construct and conjugate for producing multiple nucleic acid copies
Inventor: ENGELHARDT DEAN L
IPC: C12Q1/686
Filed: 1995-01-12
Abstract: This invention provides inter alia an in vitro process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter--independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct. Another aspect of this invention concerns a protein-nucleic acid construct in the form of a conjugate linked variously, e.g., covalent linkage, complementary nucleic acid base-pairing, nucleic acid binding proteins, or ligand receptor binding. Further disclosed in this invention is an in vivo process for producing a specific nucleic acid in which such a protein-nucleic acid construct conjugate is introduced into a cell. A still further aspect of the invention relates to a construct comprising a host promoter, second promoter and DNA sequence uniquely located or the construct. The host transcribes a sequence in the construct coding for a different RNA polymerase which after translation is capable of recognizing its cognate promoter and transcribing from a DNA sequence of interest in the construct with the cognate promoter oriented such that it does not promote transcription from the construct of the different RNA polymerase.
