Title: Bandage with pressure responsive indicator
Inventor: SIMJIAN LUTHER G
IPC: A61F15/00
Filed: 1986-11-19
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE           A bandage useful, for instance, in medical applications includes a rupturable sheet or strip having encapsulated fluid (liquid or gas). The sheet or strip is disposed between the body portion to be bandaged and the outer surface of the bandage The sheet or strip ruptures when a predetermined pressure is exceeded, thereby releasing the fluid for indicating that the bandage is applied too tightly. When the fluid is a liquid, such as a dye, the released liquid will stain the bandage. When the fluid is a gaseous substance, the release of the gas will be sensed. When a plurality of strips are used, one strip may contain a liquid and another one a gaseous substance, the strips rupturing at different predetermined pressures.

Patent CA-1304268-C (CA)
Inventor: WANDERER ALAN A
IPC: A61M5/50
Filed: 1987-10-09
Granted: 1992-06-30
Abstract: Abstract of the Disclosure A needle guard attached to the barrel of a hypodermic syringe encloses and shields the needle against contamination prior to use and prevents inadvertent direct contact therewith by medical personnel after use.  Development of an aperture at the end of the needle shield to accommodate protrusion by the needle is effected by a removable member. Translation of the needle guard along the syringe barrel to uncover and recover the needle is effected by manipulation from a location rearwardly of the needle point to further protect the medical personnel.  A double ended needle, usually used with a collection tube holder of a blood evacuation system, includes a needle guard which may interlock with the holder upon translation of the needle guard to expose the anterior needle and to prevent inadvertent disengagement with the holder and resulting exposure of the posterior needle.  An extension of the interconnection between the double ended needle and the holder permits large girth holders to be employed without compromising the preferred needle entry angle. Other embodiments of the needle guard include telescoping guards to shield lengthy single needles and double-ended needles, each of which is manipulated from a location rearwardly of the respective needle end. The configuration of the needle guard permits manipulation with only one digit of one hand which frees the other hand to perform functions related to blood collection of injection. An annular trough within the needle guard restrains outflow of and contamination by any fluids which may have dripped from the needle into the needle guard.

Title: Dynamically adaptive environment for computer programs
Inventor: EVANS WAYNE O
IPC: G06F9/44
Filed: 1988-08-25
Granted: 1991-07-23
Abstract: DYNAMICALLY ADAPTIVE ENVIRONMENT      FOR COMPUTER PROGRAMS            Abstract of the Disclosure Multiple versions of a given system command are run on a single operating system by using one command processing program per command irrespective of its version.  Each version of the command has a command definition which has the same format for all counterparts of the command. A command analyzer program transforms the parameters of a command character string into the correct data form for its command processing program based on the command definition for that version of the command.  Multiple sets of command definitions are place in separate storage directories called libraries.  The libraries are searched based on a version identifier to find the command definition for a command.  The version identifier may be specified as a program attribute, entered interactively or entered by the system. Multiple programs written with different versions of commands may be run in conjunction with each other and the system will dynamically adapt to the version of each program as it is running.  Also more than one command definition library may be searched to process a command.  Therefore, commands written in various versions may be embedded in the same program and the system will dynamically adapt to multiple versions of commands in a program.

Abstract: IMPROVED MEMBRANE SEPARATION SYSTEM AND PROCESS              Abstract of the Disclosure Condensation of feed gas constituents within a membrane system are efficiently and effectively precluded by positioning the membrane system within an insulated enclosure heated to maintain superheat conditions for the feed gas passing to said membrane system.  The membrane modules within the system are not individually insulated.  A constant, stable temperature environment can readily be maintained within the enclosure, and advantageous flexibility can be achieved in the controlling of the operating temperature for process optimization purposes.
