Title: Method and circuit arrangement for automatic character recognition on documents
Inventor: MITTELBACH HELMUT
IPC: G06V10/75
Filed: 1991-09-26
Abstract: Abstract The  image  data  (BDAT)  associated  with  a  respective document are transmitted to one of a plurality of recog-nition units for the processing of a recognition process comprising a plurality of partial processes. The alloca-tion of the processing jobs and the monitoring of the time cycles of the recognition processes is performed by a control unit (AU), by mean of which a timer is trig-gered to set the processing time of the recognition process in a recognition unit (e.g. RUn), the value of which is compared with an expected value for the process-ing time of the partial process currently running. The partial process results here from the processing status of the recognition unit which is determined by status information and can be called at any time. If the status of the recognition unit is such that, on the basis of the time comparison, no potentially successful execution of the entire recognition process can be expected,  this process can be prematurely terminated by the control unit (AU)  so as to be available for accepting new document data, especially when all available recognition units are already busy with recognition tasks.

Title: Safe-t-slide
Inventor: BONAZZA VINCENT
IPC: A63B69/00
Filed: 1993-03-12
Abstract: ABSTRACT    In the game of baseball, softball, slowpitch and the like; in many occurrences the bases are strapped to pegs driven into the ground.     In this invention a Hook and Loop system (eg. Velcro) is attached to the underside of a baseball base and the top side of a beveled rubber base pad which is anchored to the ground by a steel spike.  The baseball base can be attached and detached to and from the rubber base pad quickly and easily.     This method of securing the baseball base is safer in that when a base runner slides into a base the base will dislodge easily; thereby preventing foot and leg injuries.

IPC: G01N33/18
Filed: 1992-02-18
Abstract: A chemical analysis method for the determination of a first organic acid in the presence of a second organic acid both of which are in a solution to be analyzed. The first step is to form a pH  adjusted solution to be analyzed such that the first acid is predominately in its unionized form and so that the second acid is predominately in its ionized form. The second step is to partition the pH adjusted solution to be analyzed from a receiving solution with a semipermeable membrane. The last step is to determine the concentration of the first acid in the receiving solution so that the concentration of the first acid in the solution to be analyzed can be estimated. Valve (15) is actuated and a predetermined volume of solution to be analyzed is added to the flowing stream of liquid buffer adjusting its pH to that of the buffer and is carried to the inside of the membrane (22). The first acid permeates into the membrane (22) from the pH adjusted solution and then out of the membrane (22) into the flowing receiving solution and is conducted to the detector (25).

Title: Thin-fingered medical glove
Inventor: CHEN MAO-CHING
IPC: A61B19/04
Filed: 1993-10-05
Abstract: ABSTRACT            A process for making medical gloves whose fingers have thinner walls than the rest of the gloves involves first depositing onto a hand-shaped glove form a layer of coagulant that comprises an ionic metal salt, then depositing an elastomeric layer.  Part of the coated form is then leeched of metal ions in the coating, and the form is overcoated with a second elastomeric layer. The overcoated layer is thinner in the part where it overlies the leeched coating.  The gloves find particular usefulness in delicate operations such as those performed by ophthalmologists.

Title: Treatment for the formation of a corrosion resistant film on metal surfaces
Inventor: FURUYAMA OSAMU
IPC: B05D7/14
Filed: 1992-10-22
Abstract: A phosphate surface-treatment bath which contains a cationic organic polymeric compound (or salt thereof) that contains at least one cationic nitrogen atom and has a molecular weight of 1,000 to 1,000,000 forms a highly corrosion resistant film on metal surfaces (e.g., iron, zinc, aluminum, etc.) that is also an excellent paint undercoat. The film preferably is one in which the resin composed of the cationic organic compound (or salt thereof) has penetrated into the grain boundaries between phosphate crystals with an accompanying formation of a phosphate crystal/resin composite.  A film formed in accordance with the present invention affords a remarkable improvement in corrosion resistance and paint adherence, compared with the phosphate conversion achieved with the same treatment, except for the omission of the organic polymer containing cationic nitrogen. In addition, even when the primer coating step is omitted, the present invention exhibits a performance approximately equivalent to the application of a primer coating on a conventional phosphate film.

Abstract: A decorative bed ruffle is capable of installation on a mattress foundation such as a box spring without removal of an upper mattress therefrom. A band of elastically stretchable material forms a closed loop adapted to be stretched to pass over the upper mattress and grippingly retained on the sides of the mattress foundation. The width of the band is such that top and bottom edge portions of the band will extend over and elastically grip top and bottom edge 5 of the mattress foundation, respectively. A decorative skirt is attached to the band ofmaterial in overlapping relation therewith, for covering at least part of a central portion of the band extending over the foundation sidewalls, and at least part of the space between the mattress foundation and a supporting floor surface. In addition to easing installation, the inventive bed ruffle provides greater retention on the foundation, permits adjustment of the skirt drop to accommodate differentheight bed frames and foundations, and can accommodate a range of mattress sizesand shapes.

Abstract: A new process of interpolymerizing ethylene interpolymer products having improved properties, such as increased onset of crystallization temperature, is disclosed. Preferably, the process comprises interpolymerizing a first homogeneous ethylene/alpha-olephin interpolymer and at least one second homogeneous ethylene/alpha-olephin interpolymer using at least two constrained geometry catalysts having different reactivities such that the first ethylene/alpha-olephin interpolymer has a narrow molecular weight distribution (NMWD) with a very high comonomer content and relatively high molecular weight and the second ethylene/alpha-olefin interpolymer has a NMWD with a low comonomer content and a molecular weight lower than that of the first interpolymer. The resultant first homogeneous interpolymer is combined with the resultant second homogeneous interpolymer in appropriate weight ratios resulting in the desired finished polymer structure. The first interpolymer and the second interpolymer can be polymerized in a single reactor or they can be polymerized in separate reactors operated in parallel or series.
