Title: Restriction of communication service accessibility among subscriber communities
Inventor: FISHER THOMAS S
IPC: H04M3/42
Filed: 1989-12-19
Abstract: Subscribers of an electronic mail system service are divided into a plurality of subscriber communities. Subscribers in each community have common rights of access to one or more communication service--the sending and receiving of mail messages--which rights are generally different from those of subscribers in other communities. Permissions to send and receive messages between any two communities are specified on each mail system in a permissions matrix, wherein each row represents a different sender community, each column represents a different recipient community, and the value stored at their intersection indicates the permission vis-a-vis the two communities. A function is invoked on the sender's mail system at message addressing, and on the sender's and recipients' mail systems at message delivery, to enable or prevent message sending or delivery according to the matrix-specified permissions. Optionally, a message-associated permission may be used to overridematrix-specified permissions.

Title: A system for the controlled release of active agents and a process for its preparation
Inventor: WENZEL UDO
IPC: C05G3/40
Filed: 1990-01-31
Abstract: A System for the Controlled Release of Active Agents and a Process for its Preparation Abstract The invention relates to a system for the controlled release of active agents and a process for its preparation,  pref-erably  an  orally  administrable  pharmaceutical  preparation for various, especially soluble, pharmaceutical agents, hav-ing even, controlled active agent release essentially caused by convective processes. The system of the invention is similar in therapeutic effec-tivity to an intravenous drip,  i.e.  the even and complete release of the active agent from the pharmaceutical prepara-tion  for  a  physiologically  and  therapeutically  practical period of time caused by essentially convective processes. This leads to a constant therapeutic blood level which gua-rantees the long-term effect of the drug whilst reducing the adverse effects and improving local tolerance in the gas-trointestinal tract at the same time. Furthermore, with the composition according to the invention of the pharmaceutical preparation and the preparation pro-cess according to the invention, damages to the shell con-trolling the release of the pharmaceutical agent will not lead to dose-dumping, as is usually the case in membrane-controlled pharmaceutical agent release, and the preset re-lease rate will be reached within a short period of time.

Title: Occlusion apparatus for converting a syringe into a non-reversible single use syringe
Inventor: IBANEZ PAUL
IPC: A61M5/50
Filed: 1990-05-18
Abstract: OCCLUSION APPARATUS FOR CONVERTING A SYRINGE    INTO A NON-REVERSIBLE SINGLE USE SYRINGE                            ABSTRACT      A single use syringe wherein the essential concept is to create a valve within the orifice that leads from the drug chamber into the chamber leading to the needle.  The valve consists of a conical washer supported within the chamber by inclined barbs formed on its outer perimeter. The barbs will only allow the washer to move in one direction; toward an orifice at the needle end of the chamber. Initially the washer is positioned so that it does not impede fluid flow in either direction.  Engaging the washer but not attached to it is an expansion plug. The expansion plug can absorb fluid and expand to force the washer against the opening leading to the needle, to thereby occlude fluid flow. The process is slow, taking at least several minutes, thereby permitting the syringe to be used once for its intended purpose before occlusion occurs.

IPC: G01S13/90
Filed: 1990-07-06
Abstract: In a method for extracting motion errors of a platform carrying a coherent imaging radar system from raw radar data, azimuth spectra continuously following each other in time are formed over a set period of time for the imaging of terrains with mainly homogenous ground reflectivities.An estimate of the ground reflectivity part  is performed with a Kalman filter and with the aid of the azimuth spectra represented and system parameters entered.  Then the antenna pattern part    is obtained by dividing the azimuth spectrum by the estimated ground reflecti-vity part.      By frequency filtering a separation of the drift angle ? (t) from the velocity Vb(t) in the LOS-     direction of the antenna is subsequently performed and then the velocity obtained is subjected to normalization   after having been integrated, from which results the displacement in the line of sight direction of the antenna.

Patent CA-2029200-A1 (CA)
Inventor: HEILMANN KLAUS
IPC: A61L2/18
Filed: 1990-11-02
Abstract: This invention relates to a method for sterilizing a medical unit comprising at least two connections for insertion into a fluid flow of a medical unit where a sterilizing medium flows through the unit.            Medical units of this type are e.g. medical filters, in particular dialyzers. A high degree of sterility is here required. This is accomplished through the following steps:   a.   inserting the unit into a system under pressure-tight coupling of the two connections to a feed conduit and discharge conduit of the system under atmospheric conditions;   b.   passing the sterilizing medium from the system through the unit for a given period;   c.   germproof closing of the two connections in the coupled state, without the same being opened, on completion of the sterilization operation.   d.   removing said unit from said system as a sterile unit with closed connections.            All steps, including the removal of the unit, are therefore carried out in a system where the sterility obtained is constantly maintained. This "inline sterilization" guarantees a high degree of sterility of the medical units treated. This invention also relates to a technical apparatus for carrying out the method (FIG.1).

Title: General purpose compound apparatus for instruction-level parallel processors
Inventor: EICKEMEYER RICHARD J
IPC: G06F9/30
Filed: 1991-03-07
Abstract: The  disclosure  deals with a  technique  for  generating compound instructions from a binary instruction stream without knowledge as to where instructions start or which bytes  contain  data  instead  of   instruction. The disclosure describes pre-processing a set of instructions (or a program) to determine statically which instructions may  be  combined  into  compound  instructions.   Such processing is done in a typical embodiment by software and/or hardware means which will  look for classes of instructions  that  can  be  executed  in  parallel  in  a particular    computer    system   configuration.     The instruction  classes  and  the  compounding  rules  are implementation specific and will vary depending on the number and type of functional execution units.   While keeping their original sequence and object code intact, individual  instructions  are  selectively  grouped  and combined  with  one  or  more  other  adjacent  scalar instructions to form a compound instruction byte stream having both compounded scalar instructions for parallel execution  and  non-compounded scalar  instructions  for execution  singly.   Control  information is  appended to identify information relevant to the execution of the compound instructions.
