Abstract: The  invention  of  the  present  application  relates  to  a magnetic  display  system  using  a  display,  wherein  a  non-magnetic substrate  is  applied thereonto with a microcapsule  coating  layer having  sealed  light-absorptive  magnetic  particles  and  light-reflective  non-magnetic  particles which are dispersed  in an oily liquid,  and a permanent magnet for causing a shift of the light-absorptive magnetic particles  in one direction and,  as a result, causing a shift of the light-reflective non-magnetic particles  in the other direction.  Objects of the invention reside in that the movability of the light-absorptive magnetic particles and the light-reflective  non-magnetic  particles  are  intensified  when  these particles are shifted in the microcapsules to invert the position, the   agglomeration  property  of  the   light-absorptive  magnetic particles after the position is inverted is strengthened,  and the combination  between  the  size  of  the  particle  diameters  of  the microcapsules and the size of the particle diameters of the light-absorptive magnetic particles and the light-reflective non-magnetic particles  is  optimized,  whereby  the  contrast  of  brightness  and darkness of characters and images formed on the display is improved and the side edge portions of the characters and images are made sharper.        For   this,   in   the   microcapsule   coating   layer,   the microcapsules  having  a  plurality  of  particle  diameters  within  a range  from  100  microns  to  1,000  microns  are  combined together. Furthermore,  as the  light-absorptive magnetic particles sealed  in the microcapsules,  the light-absorptive magnetic particles having a plurality of particle diameters ranging from 0.2 micron to several microns  are  used.  Furthermore,  a  suitable  amount  of  magnetic particles having characteristics capable of becoming the permanent magnet  when  magnetized  after  the  microcapsule  coating  layer  is coated  is  added.  Furthermore,  the mean particle diameter of  the light-reflective non-magnetic particles sealed in the microcapsules ranges from 0.01 micron to several microns. Furthermore, a suitable amount  of the microcapsules  having a particle diameter  far more minute than the mean particle diameter of  the microcapsules  and having  sealed only the  transparent  oily  liquid  is  added to  the microcapsule coating layer.

Abstract: A system and method for facilitating facsimile transmissions has one or more store and forward facilities (8, 18) each asso-ciated with a plurality of subscriber facsimile machines (1, 3, 28, 30), typically coupled over the switched telephone network. The store and forward facilities include a computer for controlling operations and mass data storage equipment. A subscriber to the system delivers an outgoing facsimile message to the store and forward facility with which it is associated, which records the fax message together with data as to originating facsimile machine and destination facsimile machine. The store and forward facility then delivers the facsimile message to the intended receiver facsimile machine, either directly or through another store and for-ward facility. If unsuccessful on an initial attempt, the store and forward facility periodically retries to send the facsimile mes-sage. The system also provides spooling of all facsimile messages for an intended receiver machine, which are all transmitted up-on making connection with the receiver machine.

Granted: 2000-06-06
Abstract: A caliper logging sonde is provided having a plurality of sensing fingers each of which is pivotally mounted to the sonde and movable with respect to the sonde in response to variations in the internal dimensions of a wellbore tube through which the sonde passes. An electrical signal which is proportional to variations in the internal dimensions of a wellbore tube is determined at regular time intervals at a series of points around the circumference of the wellbore tube. A maximum and minimum dimension for each point around the circumference of the wellbore tube during a selected time interval is temporarily stored and thereafter transmitted to the surface at regular intervals. A high density array of sensors is provided by utilizing a transducer plate having a large number of cylindrical apertures disposed around the circumference thereof. Thimble members, each having an internal chamber and an elongate body narrower than the cylindrical aperture are fixedly inserted into one end of each of the detector plate apertures while an associated electrical coil is inserted into each aperture from the other end, surrounding the elongate body. Movable magnetic rods within the internal chamber of each thimble are then variably positioned in response to movement of the sensing fingers and the variable inductance of each electrical coil is then utilized to produce an electrical signal proportional to variations in the internal dimensions of the tube under measurement.

Abstract: Osmotically driven drug delivery devices with walls of porous hydrophobic materi-al as the sole diffusion-limiting wall component are disclosed. Despite pores which are considerably larger than the molecular dimensions of non-volatile species in the interior of the device, despite pores which by their hydrophobic character do not permit the pas-sage of liquid water, and despite the absence of a cellulosic semipermeable membrane, the devices absorb water by osmosis without loss of the non-volatile species, and function in a manner analogous to osmotic pumps of the prior art. By permitting the use of hydrophob-ic substances as the wall material, the invention permits the device to be constructed en-tirely from biodegradable materials.

Title: Measurement of cross-linking by products in crosslinked polyethylene
Inventor: BAMJI SOLI S
IPC: G01N33/44
Filed: 1994-10-14
Granted: 2002-04-02
Abstract: At present, concentration of the crosslinking by- products crosslinked polyethylene used as insulation in high voltage cables is determined by a cumbersome, time consuming method involving taking a sample of the polymer, extracting volatile crosslinking by-products which affect the strength of the cable, and analyzing the by-products using a mass spectrometer. A novel method of in-situ measurement of the concentration of the crosslinking by-products in power cable insulation includes the step of detecting the thermoluminescence emitted during the initial heating required to reduce the crosslinking by-products in the polymer prior to the electrical tests. Measurement of the intensity of thermoluminescence provides a direct indication of the by- product concentration which can be correlated to the electrical strength of the insulation.
