Title: Catheter balloon
Inventor: KANAZAWA SHIN-ICHI
IPC: A61F2/958
Filed: 1989-08-31
Granted: 1995-12-26
Abstract: In a catheter balloon comprising a catheter having a balloon at the tip thereof, a part or whole of the balloon comprises a membrane that is composed of a medicament-carrying material that can release the medicament gradually, and/or the medicament solution is contained within the balloon and the balloon membrane has a plurality of pores for releasing the medicament gradually.  Such a catheter balloon is useful for the prevention, diagnosis and treatment of diseases such as thrombosis, blood vessel stenosis and obstruction accompanying atherosclerosis, and minimizes the risk of accompanying the cure with additional damage to the blood vessel into which it is inserted.

Title: Liquid treatment of and liquid extraction on a paper pulp
Inventor: FUNK ERWIN D
IPC: D21C9/02
Filed: 1989-09-25
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE      It is desirable to be able to treat medium consistency (e.g. about 8-12% by weight) paper pulp suspensions with treatment liquid (e.g. a wash liquid), and to thicken the pulp to about 30-50% consistency at the same time.  A moving (e.g. rotating) channel is defined by a root wall and upstanding side walls -- some or all of which are perforated -- and treatment liquid is introduced by an arcuately elongated distributor with perforated side walls into the center of the pulp within the channel, filtrate flowing out through the perforated walls.  A pivoted wall portion of the stationary housing of the treatment device restricts outflow of the thickened pulp cake from the device, the cake flowing between a doctor blade and the pivoted wall portion.

Title: Cable television system selectively distributing pre-recorded video and audio messages
Inventor: POCOCK TERRENCE H
IPC: H04N7/16
Filed: 1990-12-06
Granted: 1994-07-26
Abstract: ABSTRACT      A  method  of,  and  a  system  for,  selectively delivering  still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes.          A maximum number of home subscribers can interactively request presentations  of  their  own  choosing to be displayed on their home television sets.   Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users.   No equipment is required in the subscriber's home.   The video is presented as still frames  from one of a number of videodisc players, transmitted over one television channel  during the appropriate time interval of 1/30th (or 1/25th) of a second.  Such video  frames,  which may  also  contain overlaid graphics information, are uniquely addressed to a remote storage device.  Unused bandwidth is used for the transmission of up to 300 discrete audio messages.            The remote storage device identifies the appropriate video still frame,  stores it,  combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel.  By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on on  television channel to 30 (or  25)   different  remote    storage  devices  for retransmission to home subscribers.   Thus, if a  home subscriber sees a given still video frame for  10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system  to transmit 300 (10 seconds x 30/second) different video frames to 300 other remote storage  devices, thereby serving 300 concurrent users.

Abstract: A pneumatic gun having an improved firing valve is disclosed wherein the firing valve is sealingly secured to the housing of the gun by a pair of rolling diaphragm seals. On the underside of the firing valve, there is a deflector having a downwardly curled outer edge operative to direct air flow into the top of the cylinder upon opening of the firing valve. The firing valve is so configured that exposure of multiple differential areas of the valve to a common high pressure results in the valve being biased toward a sealed position relative to the cylinder of the gun while in the unfired position.

Abstract: An ATM switching system includes two ATM switches which are the same as each other.  Each of the ATM switches includes a switch buffer, and a cell counter which indicates the number of cells in the switch buffer.  Each of the ATM switches also includes a difference calculator, which calculates the difference between the number of cells in the two switch buffers when one of the ATM switches is changed from an out-of-service state to a slave mode.  At this time, the other ATM switch operates in a master mode. Each of the ATM switches further includes a dummy cell generator, which generates a number of dummy cells which corresponds to the difference calculated by the difference calculator.  The generated dummy cells are written into the switch buffer in the slave mode.  When it is determined that when all of the dummy cells have been output from the switch buffer, the two ATM switches are synchronized with each other.
