Title: Improvements in or relating to ground-working implements for use with tractors having automatic depth control
IPC: A01B63/112
Filed: 1951-04-14
Abstract: 761,041. Agricultural implements. MASSEYHARRIS-FERGUSON (SALES), Ltd., [formerly FERGUSON, Ltd., H.]. April 21, 1952 [April 14, 1951], No. 8743/51. Class 6(1). [Also in Group XXXI] A light-draught implement, such as a hoe or weeder, is provided with means for multiplying the draught-resistance variations so that these may operate the automatic depth-control system of a hydraulic-lift tractor, these means including a primary hydraulic cylinder 49 attached to the implement and a secondary cylinder 51 hydraulically connected to the first and adapted to act on the tractor draughtlinkage. The implement comprises two parallel tool-bars 12 carrying tool-assemblies 13 consisting of discs 37 and hoes 39, 40, each assembly being mounted on a bracket 35 suspended by parallel links 43 from the tool-bars 12. The tool-bars are mounted on the lower draught links 6 of the tractor and include the usual bracket structure 11 pivoted to the upper draught link 18. The latter is not pivoted to the rocker 4, as usual, but to an adjacent member 20 on the tractor. Pivoted between the bracket 11 and the rocker 4, parallel to the link 18, is a hydraulic piston and cylinder unit 51, 61 connected by flexible piping 50 to similar, smaller devices 49 on the tool-bars adjacent to each tool-assembly. Variations in draughtresistance on the tools cause movements of the links 43 which operate the hydraulic devices 49. Since the pistons of the cylinders 49 are smaller than that of the cylinder 51 a magnified movement is transmitted to the rocker 4 to actuate the depth-control mechanism and cause movement of the whole implement on the draught links. The cylinders 49 are interconnected hydraulically and therefore permit mutual adjustments of working depth between the various units 13. To eliminate weight-effects, balance-springs 60 are connected between the links 43 and the tool-bars 12. Lateral adjustment of the whole apparatus on the draughtlinks 6 is effected, through a steering arm 14, by an operator on a seat 25. Specifications 470,069 and 761,116 are referred to.

Title: Monitoring of Pal Signal Waveforms
Inventor: CARNT PETER SWIFT
IPC: H04N17/02
Filed: 1967-02-24
Abstract: 1,180,577. Colour television. RCA CORPORATION. 20 Feb., 1968 [24 Feb., 1967], No. 8835/67. Heading H4F. Relates to apparatus for providing selective identification and display of the four unique fields in a PAL colour television system to allow examination of the PAL waveform in the vicinity of the field sync interval. In a first embodiment where the PAL signal waveform to be monitored also includes a half-line frequency master binary output (related to the line-by-line switching of the sync burst phase), trigger pulse generation is achieved from the relationships between the sync pulse and master binary waveforms peculiar to particular fields. Switch selection of particular combinations of sync pulse responsive signals and master binary wave responsive signals enables selective generation of trigger pulses for initiating the display of any particular one of the fields of the four field sequence. In a second embodiment the distinctive make-up of the PAL composite video signal waveform alone (in particular the timing of the first colour burst with respect to the vertical sync pulses for each field) is utilized to identify the particular fields in the four-field sequence. Further, utilizing the second embodiment the field phase coincidence of differently sourced PAL signals may be determined. The four unique vertical blanking interval waveforms may be simultaneously displayed one above the other in a predetermined position sequence.
