Filed: 1973-07-09
Abstract: 1435953 Invertible ploughs G THIEME 9 July 1973 [11 July 1972] 32614/73 Heading A1B Plough shares 58, 60 are carried on an anchor-shaped assembly 56, 57, 59 which is mounted on a pivot 55 on a frame 52 which is itself turnable about an axis 54. The plough share 58 is maintained in the position shown by hydraulic pressure in a jack 75 and if an obstacle is encountered the plough can lift by pivoting about the axis 55 causing an increase in pressure in a hydro-pneumatic accumulator 81. This pressure restores the plough to its operative position. To reverse the plough shares the hydraulic pressure is released, tension spring 74 reduces the length of the jack 75 causing link 61 to pivot about 55, pin 67 following the path 84. When past the dead centre the pressure is re-applied and lug 62 on the link 61 is forced into contact with stop 65. The arm 56 is lifted, rotating about the pin 55 until reaching stop 83. The frame 52 is then turned through 180‹ about the axis 54 and the plough share 60 takes up the operative position. In a modification a double-acting jack is used so that the spring 74 is not required.

Abstract: 1,013,036. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 29, 1963], No. 32658/64. Heading G4R. In a character reading apparatus of the kind in which the character outline is followed by a scanner to produce recurrent horizontal and vertical deflection waveforms, apparatus is provided for dividing these waveforms into a fixed number of different ranges of values by first generating voltages representing the maximum and minimum values of the waveform, the difference being divided into ranges by intermediate voltages, a plurality of detectors each controlled by adjacent pairs of the intermediate voltages to give an output when the waveform lies in the corresponding range. In Fig. 2, the treatment of the horizontal and vertical deflection signals is similar and only the latter will be described. The extreme positive and negative values of the vertical deflection voltage are stored on capacitors 403v and 413v by constantly comparing the charge on the capacitor with the deflection voltage and gating current with the capacitor whenever the charge is exceeded. At the end of the first pass round the character the extreme values appear at the two ends of potential divider 420v tappings of which give the intermediate voltages. The vertical divider 420v has five zones while the horizontal divider 420h has four. Four ranges are shown at A-O in Fig. 3 dividing the total range with four equal parts. Detectors 421v-425v are each connected across sections of the divider 420v and the vertical deflection voltage is applied to all of them. The four outputs from the horizontal circuit on leads 431h-434h are gated with the outputs on leads 431v-435v and the resulting signal indicates in which cell of a 4x5 matrix the scanning spot lies.

Title: Circuit arrangement for the storage of a signal voltage ofpredetermined level
IPC: G04G99/00
Filed: 1976-08-06
Abstract: An electronic circuit arrangement designed to store for an indefinite period a signal voltage of predetermined magnitude briefly applied thereto, comprises a main storage capacitor Cs connected via a first semiconductor switch T1 across a supply of unipolar voltage and via a second semiconductor switch T2 across an ancillary storage capacitor Cx, the latter lying in series with a binary capacitor Ci between two conductors M,  PHI 1 across which a clock pulse V PHI 1 is periodically generated. The semiconductor switches are field-effect transistors of the insulated-gate type (IGFETs), the gate of the first IGFET T1 being tied to the junction X between the ancillary storage capacitor Cx and the gate of the binary capacitor Ci; this junction X communicates with the junction S between the two IGFETs and the main storage capacitor Cs in the conductive state of the second IGFET T2 whose gate receives a series of unblocking pulses V PHI 2, lagging behind the clock pulses V PHI 1. The unblocking pulses may be generated at the same cadence as the train of clock pulses, in interleaved relationship therewith; they could also be derived from the junction S between the first IGFET T1 and capacitor Cs by having that junction tied to the gate of the second IGFET T2, the latter thus acting as a diode which conducts after the first IGFET T1 has been turned on to recharge the capacitor Cs. The generator of clock pulses V PHI 1 may serve as the voltage supply for the first IGFET T1 by having one of its conductors,  PHI 1, joined to the channel of that IGFET via a third IGFET T3 connected as a diode.
