Title: Method in calendering of a paper web and a calender that makes use of the method
Inventor: KOIVUKUNNAS PEKKA
IPC: D21G1/00
Filed: 1994-02-23
Abstract: (57) Abstract The invention concerns a method and a calender in calendering of a paper web, wherein the paper web (W) is passed through a calendering nip (N), which calendering nip (N) is formed between a roll (22) which has been provided with a soft face by means of a coating or in an equivalent way and a heatable hard roll (21). The heatable roll (21) is heated so as to plasticize the surface layer of the paper web (W) that is placed at the side of the heatable roll (21), preferably so that the temperature of the surface layer in the calendering nip (N) exceeds the glass-transition temperatures of the polymers contained in the paper. In the method, before entering into the calendering nip (N), the paper web (W) is moistened, so as to lower the glass-transition tem-peratures of the polymers contained in the paper, and pre-heated. The pre-heating of the paper web (W) is carried out by bringing the paper web (W) into contact with the heatable roll (21) before the web enters into the calendering nip (N) and by, before the calendering nip (N), feeding steam or water onto the face of the paper web (W) that is placed at the side of the heatable roll (21) so as to improve the transfer of heat from the hot roll to the paper web (W).

Abstract: ABSTRACT OF THE DISCLOSURE          Discloses a deaeration method for eliminating dissolved gases from a liquid product, which method involves low initial cost and running cost, compact equipment, and simple arrangement to accomplish the deaeration.  For the method to eliminate dissolved gases from a liquid product, a deaeration module which is divided by a gas-pervious membrane into a liquid phase side and a vapor phase side is used.  A deaeration-use gas composed of one or more kinds of inactive gases is previously dissolved in a liquid product to be deaerated, whereby a deaeration-target liquid is prepared.  The deaeration-target liquid is distributed on the liquid phase side, in which distribution process the deaeration-use gas moves to the vapor phase side via the gas-pervious membrane, while the dissolved gases move to the vapor phase side along with the movement of the deaeration-use gas.  This movement of the gases is carried out during passage through the deaeration module.

Title: Photoactivatable chemiluminescent matrices
Inventor: PEASE JOHN S
IPC: G01N33/532
Filed: 1993-07-30
Abstract: Methods for labeling a material are disclosed. The methods comprise combining with the material (a) a photosensitizer capable upon irradiation of generating singlet oxygen and (b) a chemiluminescent compound capable of being activated by sing-let oxygen wherein the photosensitizer and the chemiluminescent compound are incorporated in a particulate matrix or a non-particulate solid matrix. The particulate matrix can be solid or fluid. The methods allow for generating delayed luminescence, which can be realized upon irradiation of the matrix. The methods have application to the determination of an analyte in a medi-um suspected of containing the analyte. One method comprises subjecting a medium suspected of containing an analyte to condi-tions under which a complex of specific binding pair (sbp) members is formed in relation to the presence of the analyte and deter-mining whether the sbp member complex has formed by employing as a label a single composition having both chemiluminescent and photosensitizer properties. Upon activation of the photosensitizer property singlet oxygen is generated and activates the chemiluminescent property. Compositions and kits are also disclosed.

IPC: H04M1/60
Filed: 1995-03-28
Abstract: A voice-actuated switching system connects one or more microphones to an audio line in accordance with the output signal levels from each of the microphones. To reduce the effects of degradation of speech signals due to reverberation and noise pickup, the switching system uses directional microphones housed in a circular enclosure and arranged in a conference array configuration with response patterns aimed outwardly from the center of the enclosure. The switching system also uses a voting algorithm to select for activation the appropriate microphones indicative of the position of one or more people speaking and a variable weighting factor for gradually turning on or off the signal from each activated microphone that is coupled to the audio line. Typically one microphone will be selected to monitor a person speaking. Since its response pattern is normally pointed in the direction of the person speaking, it is less sensitive to speaker echo due to reverberation. If two people are simultaneously speaking on opposite sides of the array of directional microphones, however, two generally opposed microphones areselected, and the amount of reverberation increases only slightly over the amount of reverberation  that would be present if just a single microphone were employed.
