Convention date, Feb. 7, 1933. [Class 6 (iii)] A machine for harvesting beets or other edible root crops is provided with a cleaning drum 17 carried on a shaft 16 extending longitudinally of the machine and mounted in bearings 15 in a frame 12 pivoted on the shaft 65 of the main wheels 12 and adjustable in inclination by a screw and nut. The roots are fed to the drum from digging irons 18 by a conveyer 19 both mounted on a frame 51, pivoted at its rear end to arms 50 rigidly attached to the frame 12 and supported at its front end by runners 80. This frame can be vertically adjusted by a hand lever 54. The digging irons 18 are carried by a yoke 35 pivoted to an inverted U-shaped member 81 secured to the frame 51 : the irons can then move laterally to engage the roots. The lifted roots pass up the irons on to the conveyer of which the lower end is situated slightly above the ends of the irons so that the roots strike the lower end and thereby have some soil shaken off. The conveyer, which is driven through a clutch that can slip should overload occur, feed the roots into the rotating cleaning drum whence they pass into a laterally extending trough 20 carried by arms 27. Cup like scoops 24 on an endless chain 23 carry the roots along the trough to a basket 26 or discharge trough.

Abstract: 564,138. Air filters. HOOVER. Ltd. (Hoover Co.). March 11, 1943, No. 3956. [Class 8 (ii)] The flexible filter of a suction cleaner is cleaned by means involving a reversed air flow. Fig. 2 shows means comprising a hollow partition 20 with a hollow stem 21 projecting slidably through the filter top and closed by a cap when the cleaner is working ; the hose 16 then carries a suction nozzle and delivers dusty air to a centrifugal separator 13 from which a fan draws air containing light, dust into the filter. The filter is cleaned by connecting the hose to the stem 21 and moving the stem and partition up and down. Fig. 3 shows an alternative form in which a pair of fixed perforated tubes 28, 29 pass through a fixed partition 25, and contain rotatable perforated sleeves. In normal use, the tube 28 is closed hy a cap and the sleeves are turned so that the fan delivers air through the perforations of tube 29. To clean the filter, the nozzle 17 of the hose and the cap 35 are removed and the sleeves turned so that alternately the upper and lower perforations of tube 29 and the lower and upper perforations of tube 28 are alone opened, the filter being drawn into contact with the partition and its lower part put under suction and then deposited dust drawn into the centrifugal cleaner 13.

Title: A device for controlling the speed of the working motor in a ward-leonard system
IPC: H02P7/34
Filed: 1950-02-16
Abstract: 668,242. Control of D.C. motors. BERTHIEZ, C. W. Feb. 16, 1950. [Feb. 17, 1949] No. 4009/50. Class 38 (iii). [Also in Group XXXV] Relates to a Ward- Leonard System comprising generator G and motor M having separately-excited series-connected field windings g and m respectively. A terminal d, which is common to the two field windings, is connected to a slider C of a potentiometer rheostat Rh. Means are provided to ensure that the field excitation of a machine is not reduced to zero when the slider is placed on an end-position of the potentiometer, so that the motor may be started under full-field conditions, and full-speed operation may be obtained without reducing the motor excitation below a safe value. Such means may comprise additional generator and motor field windings, Fig. 2 (not shown), which have constant excitation and provide limiting values of flux when the energization of the respective main field windings have been reduced to zero. In a modification, Fig. 3 (not shown), abutments are placed near the ends of the potentiometer for limiting the length of travel of the slider. In Fig. 4 the abutments are replaced by resistors Rg and Rm connected between the ends of the potentiometer and the terminals of the excitation source. Resistors RTg, RTm determine the maximum excitation of the field windings g and m respectively. Closure of switch I ensures full motor excitation, and operation at rated speed is provided by respectively opening and closing switches I and I2. A rectifier S prevents short-circuiting of a portion a-C of the potentiometer due to possible simultaneous closure of switches I1, I2. A compensating resistor R has an ohmic value related to that of the rectifier so as to provide the same value of motor field current whether switch I or switch I2 is closed with the slider C engaging terminal a. The potentiometer may have several sliders Fig. 7 (not shown), each connected through a switch to the interconnection of a pair of rectifiers which are in series between the motor and generator main field windings. The pairs of rectifiers are in parallel and are poled in the same direction. The rectifiers prevent short-circuiting of portions of the potentiometer due to simultaneous closure of the switches connected to the various sliders.

Title: Servo systems for synchronizing video tape recorders
IPC: G11B15/467
Filed: 1970-01-28
Abstract: 1280603 Automatic speed control AMPEX CORP 28 Jan 1970 [17 Feb 1969] 4115/70 Heading G3R In an automatic synchronizing system for a motor driving the capstan of a video tape recorder, motor speed is controlled by (a) the relative phase of frequency-divided capstan tachometer pulses and reference pulses during recording and (b) the relative phase of synchronizing pulses recorded on the tape and reference pulses during playback, change-over from playback to recording being effected without undue phase shift by selection of a tachometer pulse close to the last tape pulse to start summation for frequency division. In Fig. 1 servosystems are provided for controlling D.C. motors 42, 110 respectively driving the head drum and capstan of a helically scanned video tape recorder. During recording and playback synchronizing pulses from a television source 18, mains 20, or an internal oscillator 22 are applied through an adjustable delay circuit 30 to a forward-backward counter 34 the other input of which receives pulses from a tachometer 40 driven by head drum motor 42 so that any lack of synchronism from a relative phase position determined by the setting of delay 30 is automatically corrected by adjustment of the motor energization through digital to analogue converter 36, 38 and shaper-amplifier 64, 68. The signal from counter 34 has upper and lower limits which, if reached, operate an indicator 70 and disable the circuit at 74. During recording, capstan motor 110 is synchronized in a similar manner by applying the synchronizing pulses, divided at 76 to frame frequency, and pulses from a tachometer 104 to a forward-backward counter 90 controlling the energization of motor 110. At the same time, with a switch 83 at "record", the frame synchronizing pulses are applied through an amplifier 84 to a head 88 recording control pulses on the tape. Then, during playback with switch 83 in the position shown, the control pulses from the tape are applied through an amplifier 132 and a transistor logic circuit 100 to counter 90 instead of pulses from tachometer 104 which are rendered ineffective by the logic circuit 100. A number of pulses, e.g. 64. are produced by tachometer 104 between consecutive control pulses from the tape and these are divided to unity at 112. As a result, if, during playback, a circuit 126 is operated to change to recording for the purpose of editing, amplifier 84, is turned on slowly, switch 83 is changed over, and divider 112 starts counting at the tachometer pulse following the last effective tape pulse so that, by virtue of the number of tachometer pulses, any phase shift is limited to that corresponding to the interval between tachometer pulses
