Abstract: 727,873. Crop sprayers. ROTTCHER, K. K. Sept. 29, 1953 [Oct. 4, 1952], No. 26732/53. Class 69 (3). A vehicle comprises a chassis 1, a front wheel 2 adapted to fit within a concrete or like watersupplying furrow 4, and two rear wheels 3 which run along the upper edges of the furrow and are driven by an internal-combustion engine 13. The engine drives a water pump 14 provided with an intake 16 connected to a nozzle 18 depending into the furrow. Two rollers 6 at the end of a lever frame 7 pivoted at 8 also run along the top of the furrow, and when the machine is inoperative a spring 9 urges the frame upwardly so that the front of the chassis is raised to bring the wheel 2 clear of the furrow bottom. During spraying, the rear end of the frame is forced downwardly by a hydraulically operated ram 11 fed from the pump 14, so that the wheel 2 rides along the furrow bottom. Handles 12 are provided together with guide rollers 5 engaging the sides of the furrow. The pump feeds a rotary reaction sprayer 19 of known type comprising an outlet 20, impeller 21, bevel gear 23 and reduction gearing 24. A cam disc 27 rotates with the sprayer and engages an arm 25 operating the engine clutch, so that once per revolution the engine is clutched to the wheels 3 and the machine is driven intermittently. A reversing mechanism which is operated hydraulically when the machine reaches a predetermined position includes a drive reversing rod 43 passing from the gear box through a guide 44 into engagement with a slide 47. The latter is reciprocated to change the direction of drive by a piston and cylinder device 52, 53 supplied with water through a part-rotary control valve 55. The control valve is operated by an arm which strikes a stake in the ground at the desired limit of travel. The pump outlet is connected to the upper end of the hydraulic ram 11 through a pipe 69, and to the valve 55 through a pipe 70. A transmission rod 71 between the frame 7 and the engine switches off the latter when the wheel 2 is raised. The pump intake nozzle 18 is as shown in Figs. 9 and 10.

Abstract: 758.933. Electric indicating systems. DECCA RECORD CO., Ltd. Jan. 3, 1955 [Oct. 1, 1953], No. 26992/53. Class 40(1) [Also in Group XX] Apparatus for determining the true position of a vessel by means of star sights comprises means for determining the difference in its position along an azimuth relative to each of two stars as obtained by a true reckoning of its position, and as determined by a sextant reading in conjunction with star sight tables, these distances being plotted on a chart relative to the true reckoning position. Each of two sextants 10, 11 (Fig. 1) is sighted on a different selected star and the angle of altitude converted electrically into a binary code by means of contacts associated with each degree position on the sextants, the binary code signals being corrected at 15, 16 for index error and height, and fed to comparison units 12, 13. A tabular unit 17 is adjusted by controls 18, 19 to give the azimuth and true altitude of the selected stars in binary code form from a punched card or magnetic tape on which these values have been recorded against the Local Hour Angle of the first point of Aries (LHA) and latitude, the latitude being that obtained from the true reckoning, and the LHA being obtained from a longitudinal control 20 set to the longitude of the assumed position and driven by a sidereal clock 21 to effect continuous change in the assumed position at the rate of one degree longitude every four minutes. The two values of the altitude of each star is fed to the computer 22 where the difference is obtained. The indicating apparatus (Fig. 2) comprises two film strips 30, 31 mounted on rollers 32, 33 and 35, 36 respectively, for axial movement, each film strip and its rollers being also mounted on an azimuth circle 34, 37 for rotation about a common axis. Each azimuth circle is adjusted angularly so that the longitudinal axis of its film strip is in the direction of the azimuth of the selected star, and its film strip is moved axially so that a cross mark on it is a distance from the axis of rotation determined by the difference value obtained from the computer 22. The two cross lines on film strips 30, 31 are projected by a lamp 42 on to a chart 45, where- . on the axis of rotation of the azimuth circles 34, 37 is made to coincide with the assumed position of the vessel, and the point of intersection of the projected cross lines indicates the true position of the vessel. The azimuth values for setting the azimuth circles 34, 37 are obtained from the tabular unit 17, or by theodolites associated with the sextants 10, 11, which may be photo-electrically controlled to follow the selected stars.

Abstract: 603,595. Exciting dynamo-electric machines. AKT.-GES. BROWN, BOVERT, & CIE. Oct. 18, 1945, No. 27334. Convention date, June 14. [Class 35] [Also in Group XXXVII] An arrangement for producing a steady change of excitation of a direct-current dynamo-electric machine, for example a generator, employing a damping- machine 4 in parallel with the main field winding 2 thereof, comprises -an additional field winding 3 connected in series with the winding 2. The damping machine is provided with a gyratory mass of variable inertia, for example a variable inertia fly-wheel. As shown, the windings 2 and 3 are provided with regulating resistors 9 and 8, which may be adjusted simultaneously. At starting, the winding 2 is short-circuited by the machine 4, and, as the speed of the damping machine increases, the excitation of the winding 3 is gradually reduced. At high speed-adjustments the winding 3 may act as a damping winding. The windings 2 and 3. may be connected in opposition. When the machine is a generator of a Ward-Leonard system, the additional field winding may form the field winding of the working-motor. During braking, the difference of the excitation supply voltage and the generator voltage may be applied to the motor field winding with which a condenser may be connected in parallel to maintain the motor field excitation substantially constant during switching from motoring to braking.
