Title: Line identifying and marking apparatus
IPC: G06K7/015
Filed: 1965-11-25
Abstract: 1,060,930. Line identifying and marking. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 25, 1965 [Dec. 2, 1964], No. 50103/65. Heading G4R. Apparatus for identifying and subsequently marking a line on a document compares data representing the position of the line on the document with data representing the position of the document relative to a line marker, during relative movement of document and marker, the document being marked on equality. The apparatus is described for use in a character recognition system, lines on the document containing an unrecognizable (reject) character being marked. Field selection.-On detection (20) of the leading edge of the document (10) at a reading station, first storage (30) sends the y and x coordinates of the beginning of the first field to be read to respective counters (51, 52) which are then decremented to zero in turn as the beam of a CRT (11) is moved vertically and horizontally respectively, by pulses produced by the beam from grids (16, 17) sensed photoelectrically (18, 19). Character recognition circuitry (25) initiates selection of the next field by the first storage (30), after reading the current field. Marking defective lines.-At the end of a line containing an unrecognized character, the recognition circuitry (25) produces a reject signal, causing the CRT beam to be moved to the top of the document, with concurrent counting (51) of pulses produced by the respective grid (16). The count is stored in a data store (100) then the beam is returned to its previous position, the pulses produced from the grid (16) during the downward sweep being used to decrement the counter (51) and the sweep stopped at count zero. After completion of reading of the document, it is ejected past a printing means (180), the document drive rotating a photo-electrically-sensed lined disc (27) pulses from which are counted (150) once the leading edge of the document has passed sensing means (160), the count being compared (170) until equality with each count in the data store (100) in turn. In each case, when equality is found, the printing means (180) is actuated and the next count ordered from the data store (100) by the printing means (or the comparator direct).

Abstract: 1,061,597. Contacting liquids with fluids through membranes. B. R. BODELL. Dec. 20, 1963 [Dec. 28, 1962], No. 50350/63. Heading B1X. [Also in Division A5] Apparatus for treating a liquid with a liquid or gas through a dialysis membrane comprises a housing having an inlet 8 and an outlet 9 for passage of the liquid through the housing and coiled tubing 16 in the housing for the passage of gas or liquid, the tubing occupying at least three quarters or substantially the whole of the housing interior. The device, for use in an artificial lung or kidney, comprises several e.g. twenty, cylindrical units 2 of transparent resinous plastic, the units being clamped between end plates 3,4 by rods 5 passing through the end plates and secured by wing nuts 6. Sealing rings 15 in one end of each of the units and in one end plate 4 ensure that the units define a fluid-tight cylindrical chamber. Blood for purification or oxygenation flows into the chamber through inlets 8 and leaves through an outlet 9, the inlets and outlet being integral with or cemented to the end plates. Each unit has fittings 22,23 each including a needle 19, (21). A length of capillary tubing 16 of material permeable to either oxygen and carbon dioxide or blood impurities, such as silicone rubber, ethyl cellulose derivatives, polytetrafluoroethylene methyl cellulose or regenerated cellulose, is connected between the needles and coiled loosely in the unit. Woven or perforated screens 14 across one end of each unit separate the capillary tubing of the units. The fittings 22,23 are connected to manifolds (28,29) for the supply and discharge of oxygen or purifying liquid e.g. Ringer's solution, to the tubing. A petcock 25 is connected by a transparent tube (27) to each unit so that bubbles entrapped in blood in the chamber may be observed and released. Generally several, e.g. six, assemblies of twenty units each are used to form one artificial lung or kidney. In an alternative construction, each unit contains several lengths of capillary tubing (Fig. 4, not shown) connected in parallel between manifolds located in the chamber and in communication with the fittings. A blood oxygenator for intracorporeal use comprises capillary tubing loosely disposed within a woven polytetrafluoroethylene tube, ends of the capillary tube projecting through the patients skin to provide a gas inlet and outlet.

Abstract: 1526990 Automatic control R F SHAW 7 Dec 1976 51079/76 Heading G3N Apparatus for detecting perivascular infiltration of intravascular infused liquids when the liquid is of a similar temperature to the patients skin surface temperature comprises a rubber impregnated nylon pad 9 which is heated by current passing through wires from a heat controller 31, and a pair of sensors one 17 of which is located immediately above the infusion point and the other 19 remote therefrom, both sensors being located within the pad, the sensor above the infusion point dropping in temperature if the liquid infiltrates, this being detected by a comparator 36 which receives signals from both sensors. If the temperature difference reaches a level predetermined by a detector 43 then an alarm is activated or a liquid flow control 25 caused to terminate infusion.

Title: Handwritten Character Representation Apparatus
IPC: G06V10/12
Filed: 1966-11-18
Abstract: 1,152,989. Recognizing handwritten symbols. INTERNATIONAL BUSINESS MACHINES CORP. 18 Nov., 1966 [6 Dec., 1965], No. 51658/66. Heading G4R. Apparatus for representing a character written by moving a writing instrument comprises means for transmitting the movement of the writing instrument to a plurality of members, each of which is displaced in direct correspondence with the component of the movement in a different respective direction, and means associated with each member for providing an output signal corresponding to the movement in the respective direction across at least one predetermined line extending transversely to the direction, the sequence of occurrence of the signals being representative of the written character. Each position on a document at which a character may be written by hand is preprinted with a grid of two horizontal and one vertical line (other possible grids are described). When the pen is moved a pantograph and other mechanical linkage supporting the pen rotate two optically-sensed marked discs by amounts corresponding to the vertical and horizontal components of the pen movement respectively. Character spacing information is read automatically or by the operator (who then keys it in) from format symbols preprinted on the document, and used to select tracks on the discs and selectively augment the pulse trains from these tracks by extra pulses obtained therefrom by frequency division, so as to supply a pulse on a respective one of three leads each time one of the three preprinted grid lines is crossed. The three leads are gated to respective shift registers provided a pressure-sensitive switch on the pen is closed. Shortly after any shift register receives a pulse, all the registers are shifted by one position. The shift register contents are passed in parallel to a diode matrix to identify the character, one of two sets of matrix outputs (letters and numbers) being gated out when the operator actuates an end of character switch, depending on the position of a " case shift " switch. The latter may be controlled manually or by the (automatically sensed) format symbols on the document to indicate whether a letter or numeral is being written. This switch is not necessary if similar characters are distinguished by being written in opposite senses. The gated matrix outputs are displayed and, if considered satisfactory by the operator, are then passed to a recorder or computer. The shift register outputs may alternatively be treated as a ternary number, one bit from each register contributing to each ternary digit with a weight of 0, 1 or 2 depending on the register. In this case the outputs are gated to a ternary adder which is partially controlled by the " case shift " switch and feeds a computer on request by the latter. The computer identifies the character by table look-up.
