Title: Module for automatically controlling a polymer processing system
Inventor: PARDIKES DENNIS G
IPC: B01F5/10
Filed: 1993-02-24
Abstract: A controller for a polymer processing system operates by emitting a controlled amplitude and frequency of coherent light (laser) energy which is scattered and absorbed by the monitored polymer dispersed throughout an instantaneous aqueous sample of a monitored material flowing continuously through a cross section of a sample chamber. The source of light energy is located an adjustable distance from one side of the sample chamber.      An optical receiver (a photoresistor with a selectable filter) measures the amount of light received on the other side of the sample chamber. An output signal of the receiver may be converted into a usable process signal which is then transmitted as an input control signal to a process controller (microprocessor or microcomputer). The process controller output and display can be configured to control and read in any suitable manner. When the monitored system has feedback, the receiver output may be applied through a feedback control loop. Active polymer solids or any other relevant engineering unit or scale, such as percent concentration, may be displayed. The receiver output signal may also operate any suitable controls of any other suitable system, such as in a dairy industry application.

Patent CA-2094535-A1 (CA)
Inventor: HULBERT ANTHONY PETER
IPC: H04W28/00
Filed: 1993-04-21
Abstract: CDMA (Code Division Multiple Access) can be used in cellular mobile radio systems to provide good spectral efficiency through averaging the interference wherever the number of users per carrier is large (several tens). This is readily practicable for voice users whose data rate requirements are modest but requies large spreading factors for ISDN data service users. This invention proposes an approach in which a multiplicity of CDMA carriers each with relatively low bandwidth are used for the voice services and overlayed with wide bandwidth CDMA carriers whose 'bandwidth occupies the whole (or most) of the band occupied by all of the narrowband CDMA carriers in order to service the data users. This allows the same RF band to service a relatively small number of data service users with wideband (and therefore higher cost) terminals without affecting the cost of terminals for the majority of voice users.

Title: Polarization-independent optical isolator
Inventor: SHIRAI KAZUSHI
IPC: H01S3/00
Filed: 1993-05-27
Abstract: ABSTRACT OF THE DISCLOSURE    An optical isolator comprises two birefringent plates one of which separates two light components whose planes of polarization are perpendicular to each other to make the two light components spatially separate between the two birefringent plates and pass through two separate optical paths and the other of which thereafter combines the two separate light components, two Faraday rotators disposed between the two birefringent plates and having a Faraday rotation angle of approximately 45 degrees, a polarizer disposed between the two Faraday rotators and having a predetermined polarized-light transmitting angle, and a magnetic field device for applying an external magnetic field to the two separate optical paths in the two Faraday rotators to magnetize respective regions near the two optical paths in each of the rotators in opposite magnetization directions to each other.  In this arrangement two light components entering the polarizer in the forward direction has the same angle of plane of polarization as the predetermined polarized-light transmitting angle of the polarizer so as to pass through the polarizer, but two light components entering the polarizer in the reverse direction has an angle of plane of polarization perpendicular -to the predetermined polarized-light transmitting angle of the polarizer so as not to pass through the polarizer.  The high performance polarization-independent optical isolator may be obtained with high isolation of more than 50 dB, which is easy in assembling or manufacturing.

Title: Coating system for running webs
Inventor: KUSTERMANN MARTIN
IPC: D21H23/56
Filed: 1993-06-04
Abstract: ABSTRACT OF THE DISCLOSURE             A coating system for material webs, specifically of paper or cardboard, includes two mutually parallel rolls directly coordinated with each other, the rolls having a mutually variable spacing such that the rolls can be positioned to create a press gap for coating the web, or so as not to create a press gap.  When the rolls are not positioned to form a press gap, the web passes over both roll shells while circumventing the applicators which have already dosed the roll shells with a coating mixture.  The web passes over both roll shells for purposes of transferring the coating mixture predosed by the applicators.  Solely the web pull in conjunction with the wrap angle of the two roll shells serves the final dosing by scraping off an excess quantity from the roll shells.

Title: A beverage package and a method of forming such a package
Inventor: LYNCH FRANCIS J
IPC: B65D25/02
Filed: 1993-10-29
Abstract: A beverage package and a method of forming such a package has a can 1 within a primary chamber 5 of which is located an insert 6 having a secondary chamber 10. The insert has a seating in the form of a bore 11 within which is received the lower end of a tube 15. The tube 15 is fitted to the insert whilst the latter is positioned in the can. When the can is charged with beverage such as beer 20 having gas in solution and sealed to form a headspace 21 containing gas at a pressure greater than atmospheric, beer from the chamber 20 may fill the tube 15. The secondary chamber 10 contains gas at a pressure greater than atmospheric and on opening the container the headspace 21 de-pressurises causing beverage and/or gas from the secondary chamber to be ejected through the tube 15 and such ejection causes froth to be developed in the headspace 21. The tube 15 isolates a major part of the beer in the container from having its gas liberated so that such gas can evolve gradually to provide sparkle in the beer when the latter is poured into a glass. The tube is preferably press fitted into the socket 11. In an alternative arrangement the tube may be received on a spigot extending from the insert 6. Preferably the seating 11 is co-axial with a cylindrical can 1 and the tube 15 is curved to locate its upper end adjacent to the side wall 3 of the can.
