Title: Character recognition apparatus
IPC: G06V10/10
Filed: 1975-12-10
Abstract: 1525479 Character recognition device RECOGNITION EQUIPMENT Inc 10 Dec 1975 50611/75 Heading G4R A hand held reader (Fig. 2, not shown) for recognizing characters on, for instance, merchandise or tags, has a source illuminating the data and a matrix of photo cells on which is formed an image of the data. As described a 32 x 32 matrix of photo cells is supplied but only a matrix 6 x 32 is scanned. The data is smaller in height than the matrix but its maximum width is equal to that of the matrix.  The matrix is scanned row by row and the signal obtained is subjected to gain control to normalize the background level signal and is converted to binary to indicate black and white level signals. The six bits from each row are clocked serially into a shift register and successive rows are clocked in parallel through the shift registers formed by registers 131-136, 131a-136a so that a 6 x 16 area of the matrix can be examined by logic circuitry. Selected areas of the pattern in the register are examined to determine whether "1"s or "0" are present. Segments Seg A-Seg J (Fig. 9a) are examined and for instance Seg A exists if each of the three pairs of locations contains at least one "1". Similarly voids 1-13 are examined in which all the cells in the given area must be white. The results of selected voids and segments are combined (Fig. 12) to determine which numerals have been read. The numerals can then be displayed. The examination of adjacent columns in the segments of voids, either of which may contain a "1" allows for skew during reading. A number is stored indicating the vertical position of an identified character and for correct read out the succeeding character must have a number within a predetermined range of the prior number. The scanner may read several lines at once and each line is provided with a register corresponding to the number indicating the vertical position. When a character is recognized a counter is set to a predetermined value. At the end of each frame, e.g. when the whole of the sensor has been scanned, the counter is decremented. The preset number has a value such that when the counter is zero the character has moved out of the scanning area and the next character can be identified. A special character may be provided which indicates the number of characters present and the direction of sweep of the reader.

Title: End Closure Member for a Tubular Nuclear-Reactor Fuel Element
IPC: G21C3/10
Filed: 1966-11-16
Abstract: 1,162,842. Fuel elements. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 16 Nov., 1966 [27 Nov., 1965], No. 51403/66. Heading G6C.

Title: Control device for controlling gaseous fuel supply to an internal combustion engine
IPC: F02M21/02
Filed: 1973-11-09
Abstract: 1445165 Controlling gas supply to IC engines LANDI DEN HARTOG BV 9 Nov 1973 [10 Nov 1972] 52046/73 Heading F1B A control device 1 for a gas operated I.C. engine having a fuel induction system including a gas supply conduit 29 connected between an evaporator/ pressure regulator 5 and a Venturi tube 3 which leads via a throttle valve 4 and an inlet manifold to the engine, and a vacuum conduit 30 connecting the regulator 5 and a point downstream of the throttle valve 4, the control device comprising a control valve 16, 18 adapted to be located in the gas supply conduit 29, and a control mechanism 6-10 for the valve adapted to be located in the vacuum conduit 30, the arrangement being such that in use opening the throttle valve actuates the control mechanism to increase the opening of the control valve. When throttle valve 4 is partly open, the vacuum communicated by conduit 30, causes diaphragm 10 to raise valve 16 to constrict opening 14 producing a lean mixture. For wide open throttle operation, the pressure above diaphragm 10 is higher, so that the opening 14 is less constricted, an effect which is augmented by the higher vacuum which is fed to the lower side of the diaphragm via conduit 32 when the flow-rate through the Venturi 3 is greater. This produces a stoichiometric mixture. The maximum air fuel ratio is adjustable by means of abutment 34. Adjusting screw 27 controls the passage 26a to enable the characteristics of the device to be varied. In another embodiment, Fig: 3 (not shown), operation under partial load causes valve 16 to rise to constrict fuel passage 14 leading to a weak mixture, but operation under full load at normal engine speed leads to a lower vacuum above the diaphragm 10 ensuring that the valve 16 is in the position in the Figure i.e. the passage 14 is unrestricted and the mixture formed is stoichiometric. At full load with the engine speed low, the vacuum above diaphragm 10 is even lower, so that valve 16 moves to a position lower than in Fig. 3 preventing the mixture from becoming too rich.

Title: Fuel injection apparatus
Inventor: ROOSA VERNON DAVIS
IPC: F02M59/34
Filed: 1968-11-20
Abstract: 1,254,454. Fuel injection pumps; regulating I. C. engines. V. D. ROOSA. Nov. 20, 1968 [Nov. 20, 1967], No.52388/68. Headings F1A and F1B. Fuel injection apparatus for limiting the rate of fuel supplied to an I. C. engine to that which it can properly combust at any particular engine speed, comprises a fuel injection pump 26, a speed governed metering valve 19 controlling an orifice 15 in the inlet duct 10, 13, 17, 18, 152 to the pump, and a second valve 20, normally open, but movable to a position limiting flow into the pump only when the metering valve 19 is in the fully open position for the particular engine speed required. Fuel enters the apparatus through a port 2 and is drawn through a passage 7 by a feedpump 8 which delivers to the inlet duct 10.... 152 containing the orifice 15. The size of the orifice 15 is determined by the axial position of the valve 19, urged to the right by the action of centrifugal flyweights 30 driven by the engine. Rightward movement of the valve 19 is resisted by a spring 40 and a substantially constant low-pressure established in a chamber 92. To alter the bias of the spring 40 in accordance with the desired speed of the engine, the spring reacts against a movable abutment 42 acted upon by the pressure of fuel in a chamber 50. The chamber 50 receives fuel from the inlet duct at 18, the fuel passing a port 62 controlled by the metering valve 19 and passages 64, 66, 70. A needle valve 48 positioned by a throttle rod 44 controls an axial spill port 46 in the abutment 42 and thereby both the axial position of the abutment and the pressure in the chamber 50. The pressure obtaining in the chamber 50 is directly proportional to the engine speed and is applied through a passage 98 to a cylinder 100. Thus a piston 102 in the cylinder 100 is subject to a force directly proportional to the engine speed. The piston 102 acts through a lever 108 loaded by an adjustable leaf-spring 108a, Fig. 3 (not shown), to cause opening of a needle valve 114, 5 when the engine speed increases. When the flow through the needle valve 114, 5 reaches the maximum desired level for the specific operating speed of the engine, the so increased pressure differential across the valve causes the downward movement of a diaphragm 128. This results in a plunger 130 restricting an orifice 143 through which feed pressure supplied to a chamber 136 escapes to an inlet chamber 6. Thus pressure builds up in the chamber 136 and deflects a power diaphragm 144 to cause pivoting of a lever 96 and consequential movement of the second valve 20 to a position in which it limits the flow from the duct 152 into the pump 26. In a modification, Fig. 4 (not shown) the operation of the valve 20 is compensated for changes in manifold pressure and temperature.
