Abstract: 693,725. Bulldozers. RUSTON-BUCYRUS, Ltd. March 30, 1951 [April 8, 1950], No. 7409/51. Class 68(i) A bulldozer comprises a dozer blade and a pair of push beams connected at their rear ends to opposite sides of the tractor, the dozer blade being permanently rigidly connected to the front end of one of the push beams and detachably or pivotally connected to the front end of the other. The push beams 1, 2 are connected at their rear ends by universal joints 6, 7 to trunnion brackets rigidly secured to the track frames of the tractor and at their fore ends to the blade 3, the beam 1 being rigidly connected, e.g. by welding to an angle iron 15 on the base of the blade, and the beam 2 pivoted by a pin 21 to a lug 22 on the angle iron 15. Rigid diagonal bracing struts 19, 20 connect the beam 1 to the blade, and the blade may be raised or lowered by a wire 16. A diagonal brace 23 rigidly connected to the beam 2 is pivoted at 24 to a lug 25 on the angle iron 15, and an adjustable brace 26 is pivoted to a lug 27 on the beam 2 and to a lug 29 on the upper part of the blade. The upper part of the brace 26 is coaxial with a threaded rod 35 which carries a nut, rotatable but axially immovable, within a housing 31 welded to the upper part of the brace 26, so that by rotation of the hexagonal hub 36 of the nut the length of the brace 26 may be adjusted. Extension or contraction of the brace 26 causes the blade to turn about the fore-and-aft axis of the tractor. The necessary twisting of the beams can take place owing to the spherical bearings in the universal joints 6, 7. In another form, the blade may he skewed by adjusting the linear or angular dimensions of the U-shaped structure between the joints 21, 28, 30. The joints 21 and 30 and the butt joint 47 in the middle of push beam 1 may be disconnected, and the blade and fore part of the beam 2 removed as a unit for stripping.

Title: Method for controlling the black level of television signals
IPC: H04N9/72
Filed: 1964-02-25
Abstract: 1,018,715. Television black-level clamping systems. FERNSEH G.m.b.H. Feb. 25, 1964 [Feb. 27, 1963], No. 7787/64. Heading H4F. Colour " burst " synchronizing signals F are separated from an N.T.S.C. type of television signal by a gate 23 rectified at 24 to obtain pulses i, and then differentiated and limited at 26, 27 to obtain pulses k occurring shortly after the bursts (i.e. during the back porch intervals) which are applied via adder 43 and pulse former 28 to control a clamp 29 connected to the channel 31, 32 through which the television signal passes. A second series of clamping pulses are derived from the synchronizing pulses g which are delayed at 37 and then differentiated and limited at 38, 39 to obtain pulses m which occur at a suitable fixed interval after the horizontal (and equalizing) pulses such that those which occur during the vertical synchronizing interval T do not ov rlap the negative excursions of the vertical synchronizing pulses. The timing of the pulses however is such that those which occur during the picture interval (i.e. outside interval D) coincide with the colour bursts F. The pulses m are applied via gate 41 which is controlled by pulses i so as to eliminate those which coincide with colour bursts and the resulting pulses n (occurring only during interval D) are then applied to adder 43 whence they are combined with pulses k to produce a composite pulse train which passes through pulse former 28 as pulse train m<SP>1</SP> to control clamp 29. If the original colour television signal comprises colour " bursts " extending throughout the interval D the whole of pulse train m will be eliminated in gate 41. If the original signal changes to a conventional monochrome signal, the absence of " burst " signals will eliminate pulse train k but will allow the whole of pulse train m to pass via gate 41 to adder 43 and thence through pulse former 28 as pulse train 28 to clamp circuit 29. Reference is made to the control of gate 41 by pulses v which coincide with interval D as an alternative to control by pulses i. A detailed transistor circuit for part 162 of Fig. 6 is described with reference to Fig. 7 (not shown). A monitor receiver for use with N.T.S.C. type signals and incorporating the system of Fig. 6 is described with reference to Fig. 8 (not shown). The receiver includes a vectorscope for the colour circuits. A system is described with reference to Fig. 5 (not shown) which includes only elements 23-27 for deriving clamping pulses from the colour synchronizing " bursts."
