Abstract: 1406717 Cutters for mowers OMARK INDUSTRIES INC 21 Sept 1972 [28 Sept 1971] 43732/72 Heading A1F An impact cutter used in a mower is formed from a blank of sheet metal and has a cutting edge 70 defined by the intersection of one surface of the blank with a planar surface 80 intersecting both faces of the blank, the blank being bent at its free end 72 forming a hook 74 on the cutting edge. The cutter also has a base 50, an offset 48, feet 44, 46, and a part tapered tang 30 which is inserted in a slot of an endless V-belt 12 and retained by a roll pin 38 therethrough. The feet entered one to each side of the tang 30, and form a concave configuration in the direction of the belt enabling it to flex over pulleys. In a modification the feet entered across the belt in the same direction with the central tang betwen them, and the cutter is secured by a roll pin and a concave washer engaging the tang behind the belt. In a further modification the cutter has no tang but is secured by a staple which engages a concave washer behind the belt. The cutters are sharpenable in use (Fig 1) by an annular sharpener 84 which can be brought into engagement with the planar surfaces 80 of the cutters as the V-belt is advanced around the drive pulley 16. The surfaces 80 and sharpener 84 are preferably horizontal but may be tilted if required. Belts 28 on the mower deposit cut vegetation through an opening 31 to form a window, and a driven reel 26 mounted above the belt 12 lays the cut vegetation back on the slatted belts 28. Specifications 1239271 and 1219440 are referred to. Reference has been directed by the comptroller to Specifications 1219440 and 1239271.

Abstract: 1,191,286. Measuring stress electrically. COURTAULDS Ltd. Sept. 29, 1966 [Sept. 30, 1966], No. 43778/66. Heading G1N. To indicate a peak stress in a fibre F, or the like, undergoing a progressive increase in strain by means of a clamp G, a voltage on line 1 representing the stress is supplied both via an amplifier A1 and a diode MR1 to a capacitor C1, which stores the maximum value attained by the voltage at any preceding time during the test, and also to input 8 of a comparator A3 where it is compared with a voltage at 7 from a potentiometer RV1 representing a predetermined proportion of the stored voltage at C1. The comparator gives an output when the stress voltage 8 becomes less than the voltage 7 indicating that the maximum stress borne by the fibre F has been passed, even though it may not yet have broken and is still under a certain strain. The comparator output operates an "end of test" relay N provided that (i) contact M1 of relay M is closed, indicating that a predetermined minimum stress has been achieved as detected by a threshold device 10 connected to a preset level potentiometer RV2; and (ii) contact L1 or relay L is closed indicating that the magnitude of the stress voltage 1 has become less than that of the stored voltage at C1 fed back to input 3 of amplifier A1. As the strain applied to fibre F is progressively increased, a series of minor stress peaks may occur due to slight reductions in stress arising, for example, from breakage of individual filaments in the fibre F. These peaks are detected by relay L and cause comparator A3 to operate the relay N if RV1 is set to a lower level. Operation of relay L also causes an indication of extension of the test fibre (by means not shown) to be interrupted, and the voltage corresponding to the extension at the point of operation of the relay to be stored on a capacitor.

Title: Improved plasma device and method
IPC: H01J17/14
Filed: 1965-10-21
Abstract: 1,123,205. Thermonuclear apparatus. GULF GENERAL ATOMIC Inc. 21 Oct., 1965 [4 Nov., 1964], No. 44613/65. Heading G6P. In a nuclear fusion device, employing deuterium or tritium, plasma confinement is effected by a multiple cusp magnetic field combined with an orthogonal electrical field. Particle loss through the points of the cusp is thereby prevented. Plasma may be formed from an unionized gas by pulsing the electric field, while to remove neutral particles from the plasma the latter may be guided along a curved path which the neutral particles are unable to follow. The magnetic field is formed by linear currents flowing in conductors, 32, parallel with the plasma central axis and the electric field is produced by charged sleeves, 58 surrounding each conductor. The conductors and sleeves are energized from the capacitors 56 and 60. The superimposed magnetic and electric fields impart a drift velocity to the plasma, along the axis 17, which is a function of the strengths of the fields and has the same direction for both positive and negative particles.

Abstract: 1476837 Printing columns of text INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [22 Jan 1975] 45266/75 Heading G4H Corresponding portions of a plurality of sequentially stored text columns (each of which contains a plurality of lines) are printed on the same print line prior to causing a printer carrier return so as to form a side-by-side column format, by a method comprising the steps of defining locations for printing lines of each of the columns, printing a line of one of the stored columns on a print line in an appropriate location, and printing a corresponding line, if any, from each of the other columns on the same print line in the appropriate location. The printer system (Fig. 13, not shown) comprises a keyboard (1) and a printer (2), a buffer (19) and control (17), a multi-column playout control (45) and an output format control (46). The control (Fig. 14, not shown) allows insertion, deletion and order changing of characters circulated through the buffer. The format control (Fig. 17, not shown) includes circuitry for justification calculations, and the column control (Fig. 16, not shown) is used to control the printer and the format control and to generate, inter alia, operation flag f and column marker CM signals. Fig. 5 shows the buffer contents for printing the page shown in Fig. 1, after printing of the two complete lines X and before printing the first line of column A. During set up for input keying, the following codes had been stored: beginning of memory BOM, the mode (justification j) to be used first, and an overall measure M1, M2. A tab field TAB1, TAB2 had also been set up to define the column locations. For columns which are stored sequentially but printed side-by-side, a column begin code CB is stored as shown. Each column is then keyed and stored in its entirety, a column end code CE being keyed and stored at the end of the last column. (Columns A, B have the same mode and measure J, M1, M2 which is stored with column A; column C requires a left flush code L and new M1, M2.) Upon playout, the buffer is scanned when a CB code is encountered and operation flag f is inserted into the data flow after the first CB code; column marker code CM is also inserted after each subsequent CB code during the scan which, upon detection of CE, continues to the beginning of the memory. When f is again detected, following characters and spaces are printed in the defined mode until a CR is detected, when the printer tabs; during the column advance operation, CM is written over f and the memory is scanned, the next detected CM being written over with a new f. Print out then continues (for each line in turn) with CR detections and column advance operations until the end of each column is reached. After printout of all columns, the CM codes are deleted and the rest of the text y is printed.
