Title: High efficiency feeder apparatus for pneumatic conveying lines
Inventor: ZITEK JOSEPH J
IPC: B65G53/28
Filed: 1990-06-28
Granted: 1998-04-28
Abstract: An  apparatus  is  disclosed  for  pneumatically conveying dry particulate material from a source to a destination by cyclically loading and unloading a transfer vessel.  The loading stage is accomplishing by creating a vacuum pressure within the transfer vessel to pull material into it, and after it is filled to its optimum capacity, switch a number of valves to convert the apparatus to the unloading stage wherein positive pressure is applied to the interior of the vessel to push the material down the output conveying line to its destination.  The motive force in the operation of both stages is positive air pressure.   The vacuum is generating by a high velocity venturi structure in combination with valving and piping which uses the positive air pressure.  The unloading stage of operation utilizes the dense phase conveying, which is high pressure, low volume conveying.

Granted: 1996-06-18
Abstract: A method and system for authentication of communications. More particularly the subject application discloses a method and apparatus whereby a third party may validate that a communication is an authentic communication from a second party sent with the authorization of a first party.  For example, the third party may be a postal service, the second party may be a mailer, and the communication may be a postal indicia showing that a mail piece has been properly franked. The first party and the second party share an encryption key, or a series of keys.  The first party also has a second encryption key which the third party has the ability to decrypted.  In the subject invention the first party encrypts a key shared with the second party with the first party's second key and transmits this to the second party.  The second party then uses its copy of the key to encrypt information and appends its encrypted information to the message received from the first party and transmits all this to the third party. The third party may then decrypt the copy of the key encrypted by the first party and use this information to decrypt the information encrypted by the second party.  The known technique of eliptical logarithms may be used to provide highly secure encryption of short messages.  The second party may be a mailer and the apparatus of the subject invention may include a postage meter which prints the information transmitted to the third party, who may be a postal service, on a mail piece as a postal indicia.

IPC: A61M1/14
Filed: 1992-07-08
Granted: 2003-01-14
Abstract: A method of monitoring a dialysis unit is provided herein. The method includes the first step of acquiring and storing set values for a plurality of parameters relating to the treatment to be carried out. The parameters include the infusion rate of a solution containing bicarbonate (HCO3-). The method then includes the step of calculating a clinical prescription of the concentration, in blood, of bicarbonate ([HCO3-]b), which will result from a treatment based on the stored values of the parameters. The clinical prescription is calculated using a mathematical model of the relationship between the treatment parameters and the clinical prescription ([HCO3-]b). The method then includes the step of comparing, during the treatment, set values of the parameters with initially stored set values of the parameters. The method then includes the step of determining suggested values for one of the parameters so as to maintain the clinical prescription ([HCO3-]b) unchanged.  If any variation is detected between the set values of the parameters and the initially stored set value of the parameter, the method then includes the step of determining any change in the clinical prescription ([HCO3-]b) resulting from the change in the set values of the parameter. The method then includes the step of generating an alarm signal when a variation in the clinical prescription ([HCO3-]b) is detected.  The method then includes the final step of displaying the suggested value.
