Abstract: ABSTRACT OF THE DISCLOSURE           The disclosed mechanical  seal  is for use between a housing and a rotatable shaft supported by the housing, and has adjacent  annular primary and mating sealing rings,  each ring having a generally radial sealing face.   Means seals and holds the first sealing ring nonrotatably relative to the housing, and means seals and holds the second sealing ring to rotate with the shaft.   One sealing ring is movable axially of the shaft, and springs urge this one ring toward the other sealing ring, which is axially fixed relative to the shaft.   The axially moveable seal ring is centered coaxially with respect to the axis of the seal  ring through engagement of a centering element which is centered relative to the shaft and which engages the axially moveable sealing ring to center it relative to the shaft.   The centering element engages the axially moveable sealing ring to effect such centering at the periphery of the axially moveable ring exposed to the pressurized fluid to be sealed.

Abstract: ABSTRACT OF THE DISCLOSURE               Improvements in a reforming process for the regeneration and reactivation of a bed of a reform-ing catalyst, notably an iridium-containing catalyst, coked and catalytically deactivated during the on-oil portion of a reforming cycle.  The reactor containing the catalyst is contained in a multi-reactor unit, the individual reactors of which are conected in series via suitable piping and valving.  The reactor can be alter-nately manifolded with production facilities during the on-oil portion of the operating cycle during which period the catalyst of said reactor becomes coked, and can be manifolded alone or with other reactors with a ferrous metal regeneration circuit during the catalyst regenera-tion and reactivation portion Or an operating cycle during which period the catalyst is regenerated and reactivated. In the regeneration and reactivation of the coked catalyst the sequence of process steps include (a) an oxidation step and subsequent reduction step, or (b) a reduction step and subsequent oxidation step, to remove coke and redisperse the iridium component of the catalyst of said reactor. Iron scale oarryover from the regeneration circuit to the catalyst of said reactor is drastically reduced by-passing said reactor during the periods of transition from the (a) oxidation step to the reduction step, or (b) from the reduction step to the oxidation step by closing off the manifold connection between the regenera-tion circuit and the said reactor.  Loss Or catalyst activity due to iron scale carryover to the catalyst of said reactor is thus suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE:     Disclosed is a splint-like element for use in end-to-end nerve suture to eliminate tension at the anastomosis site and thus allow optimal coaptation between the nerve ends to be sutured.  The element comprises an elongated body made of a material that is rigid and slightly resilient and is biologically acceptable, such as silicone,  The body is long enough to have one end attachable to the epineurium of one of the nerve ends by at least one but preferably two longitudinally  spaced-apart  sutures,  and  another  end attachable to the epineurium of the other nerve end also by at least one but preferably two other longitudinally spaced-apart sutures.   The element  also comprises pieces  of reinforcing material preferably consisting of beads of plastic material embedded into the body material wherever this body is intended to be attached to the epineurium to prevent the body material from being torn or otherwise cut by the sutures.  In use, two such splint-like elements may be attached symmetrically to the epineurium of the nerve ends while the same are held into contact in order to make the suture site tension free.  Then,  the nerve ends may be sutured as is known in the medical art to achieve the requested anastomosis.

Title: Method for presenting compressed electronic day calendar information in an interactive information handling system
Inventor: STROPE GERALD C
IPC: G06Q10/00
Filed: 1989-01-25
Granted: 1993-02-02
Abstract: ABSTRACT     A method of simultaneously displaying day calendar information on the screen of an interactive terminal of an information handling system along with data being processed by an application program. The day calendar data is display-ed in a first view port in a compressed format which indicates busy and free time periods, while data from an application program is displayed in a second viewport. The information in the two simultaneously displayed viewports provides an improved interactive user interface in that the terminal user does not have to interrupt the task that he is working on to determine the availability of a certain time period. When the terminal is interconnected to other termin-als by a network, the method provides an indication in the first viewport for the terminal user that is actively engaged in an application program, that a second user of a terminal on the network has calendared an event on the first user's calendar. The terminal user has the option of viewing the event immediately or at some other time that is more appropriate. The method also allows the terminal user to display day calendar data in compressed mode either for the next day or the previous day merely by selecting specific buttons displayed in the second viewport for this function.

Abstract: PHOTOFINISHING APPARATUS WITH FILM INFORMATION EXCHANGE SYSTEM USING DEDICATED MAGNETIC TRACKS ON FILM               ABSTRACT          A virtually transparent magnetic layer is included as an additional layer in a color negative film.  Information exchange between various users of the film--such as (for example) the film manufacturer, the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film that begin and end within each individual frame.  Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame.  The photofinisher-dedicated tracks fill the image-bearing area of each frame. The film has only a single film perforation along one edge for each frame.  The camera-dedicated tracks lie along the edges of the film between the film perforations.  Each track begins and ends within a single frame, and is divided into a plurality of fields.  The spatial relationship between the start location of the tracks associated with each film frame and the corresponding perforation determines the spatial relationship between the magnetic heads and the perforation sensor in the photofinishing apparatus.
