Patent EP-0096716-B1 (EP)
IPC: G06V30/19
Filed: 1982-12-15
Granted: 1987-08-12
Abstract: An optical character recognition system includes a video processor (12) for generating data representing a character pattern on a document, this data being represented by pixels quantized into white, gray and black levels. A character pattern represented by this data is enhanced in enhancement means (13) by successively evaluting pixels forming the character pattern and selectively changing the evaluated pixels on the basis of an analysis of data representing adjacent pixels. During enhancement, gray pixel data is changed to black or white, while some black pixel data is changed to white. The enhanced data is scanned in finder means (15) to determine when a character pattern is optimally positioned in a window. The character pattern is then sequentially compared with sets of data representing templates of potential characters in order to recognize the character pattern. The system can recognize characters in a variety of fonts and on documents cluttered with extraneous optical patterns.

Abstract: In apparatus for preparation of a medical infusion solution, especially for the treatment of the urema by means of haemofiltration or peritoneal dialysis, infusion concentrate from a container (9) is mixed in desired ratio with high purity water in a mixing tank (15), the mixing ratio is determined and controlled gravimetrically by a weighing machine (26) and control device (27) and the concentration is checked continuously through measurement of the electrical conductivity of the solution by a conductivity meter (17). The high purity water is additionally filtered by sterile filters (13, 39) and the desired infusion solution is filtered through an ultrafilter (20) to be free of pyrogens for in-line infusion into the patient. All apparatus components such as concentrate supply container (9), electromagnetic valves (V1 to V8), pumps (P1, P2), pressure meter (19), conductivity meter (17), ultrafilter (20), sterile filters (13, 39), weighing machine (26) and control and regulating device (27) are located in a frame (40).

Abstract: A device for introducing dosed or proportioned quantities of pulverized solid materials into a carrier gas stream is presented. The device comprises a housing which defines a flow chamber in the axial direction for the flow of pressurized fluid or carrier gas. The housing also has a side aperture therethrough. The side aperture is connected to a container holding pulverized materials. Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing. The outer sleeve communicates with the aperture while the inner sleeve has an axial bore which provides a passage for the carrier gas. Upon rotation of a sleeve, slots provided on each sleeve will align and overlap with each other and with the aperture to define a variable sized passage between the container and axial bore whereby the pulverized material is delivered therethrough to the carrier gas stream. A third sleeve which is coaxial with the inner and outer sleeves and rotatable about its longitudinal axis is located between the housing and the outer sleeve. This third sleeve has a radial aperture corresponding to the side aperture of the housing. The third sleeve acts as a valve between the dosing device and a distribution tank.

Granted: 1990-08-01
Abstract: The invention relates to a blank for a tool die, made of compound steel with a core of high speed steel and a surrounding ring of a different steel, said ring bringing about a prestress in the core. According to the invention, the prestress is due to the fact that the core consists of a high speed steel powder which has been compacted to full density, that the ring consists of a steel alloy, the residual austenite transformation to martensite and consequent volume increase of which is zero or considerably less than the residual austenite transformation to martensite of the high speed steel after the same heat treatment, and that the blank has been hardened and annealed to create in the core a compression stress as a result of the obstruction by the surrounding ring of the volume increase of the core.The invention relates also to a method for manufacturing such blanks. A high speed steel powder is filled into a thick-walled pipe, said pipe consisting of a steel different from high speed steel. The pipe is closed and subjected to hot isostatic compaction causing the high speed steel powder to become compacted to full density, forming a compact core in the pipe, so that a compound material is obtained. The pipe is cut into several discs or pieces of suitable lengths. The material is hardened and annealed, the high speed steel core during heat treatment undergoing a greater residual austenite transformation into martensite than the surrounding ring, a compression stress thus being created in the core.

Abstract: The cover has the nature of a splint and/or mould which is adapted for temporary use on the injured digit of a person's hand or foot in order to foster beneficial healing after a nail plate has been removed. The cover or splint comprises a generally elongated sheet (12) of thin (i.e., 0.020 inch (0.5 mm)) polypropylene or the like, which is inert to body fluids. It has a generally compound curvature so that it approximates the natural shape of a human nail plate, and has on its lower surface a smooth, concave shape which is adapted for contacting the healing nail bed. The sheet has a proximal end (18) that is approximately perpendicular to the sides of said sheet, and the sheet has "square" corners which fit with-in the eponychial fold of the person's digit--for the purpose of preserving the fold and maintaining its size. The split also has a structure (20) depending from the two sides of the sheet for engaging the tissue of the person's nail bed; this structure (20) holds the tissue and inhibits it from contracting significantly during healing of the nail bed. The healing nail bed is restricted to taking on the smooth shape of the juxtaposed sheet as it heals, and a healed nail bed will have a size that tends to be almost as large as its pre-injured size.

Abstract: This invention concerns a multiple loudspeaker with a piezo-electric "tweeter", held up by a means of support which allows the rear wave emitted by the ceramic disk and respective conical diaphragm to be fully exploited, using the main loudspeaker cone as a reflecting surface without overloading the moving coil of the latter. The invention is basically characterized by the fact that the piezoelectric "tweeter" is placed in front of the main loudspeaker cone, without the traditional protection and support basket, but using a different means of support which does not intercept or disturb the rear radiation from the piezoelectric "tweeter", or prevent the forward reflection of the radiation by the main loudspeaker diaphragm.

Filed: 1986-03-18
Granted: 1989-10-11
Abstract: A piezoresistive force-measuring element comprises at least two force-introduction plates with an electrical conductor subjected to plastic deformation arranged between them. The force-introduction plates transmit the forces acting on them without mechanical shunting onto the conductor between them. The change of electrical resistance caused by the force sustained can be used to measure force, accompanied by plastic as well as elastic deformation of the conductor. The typically annular or rectangular force-introduction plates can be fitted inside a housing which may include a bridge circuit for determining the resistance change as well as other electronics enabling the device to be used as a transmitter. By placing the conductor in grooves or anchoring it in the pores of the adjacent plates, an essentially hydrostatic loading of the conductor is obtained, bringing an enormous extension of the measuring range while the measuring accuracy is enhanced owing to the reduced hysteresis. The sensitivity and the measuring range can be adjusted by appropriate prior deformation of the conductor. Permanent deformation of the conductor resulting from high loads makes possible subsequent determination of the magnitude of the peak forces acting on the measuring element.
