Abstract: ABSTRACT OF THE DISCLOSURE         A  tractor  draft  load  monitoring  system responsive  to tractor and associated implement  load changes.   The  system is  particularly adapted  for  a tractor  having  an  engine/transmission  power  unit coupled to its drive shaft.  The power unit is mounted on the frame by resilient mounts that permit measurable angular displacement of the power unit relative to the frame about the drive shaft axis in reaction to changes in the drive shaft torquè.  The working depth of the implement, which may be tractor mounted, semi-mounted or a pull type implement, is raised or lowered by a hydraulic lift system that is controlled by a control valve assembly connected to a source of fluid under pressure.   Interposed between the power unit and the control valve assembly is a transmission cable (Bowden wire  type)  and  lever  system  that  is  operative  to transmit angular displacement of the power unit to an actuating member of the control valve assembly to cause hydraulic actuation of the hydraulic lift device to change the working depth of the implement to compensate for changes in its draft load.   The lever system is coupled to a manual operating means which may be moved to an extreme implement raising or lowering position causing fluid flow to bypass the control valve, thereby nullifying its effect.

Abstract: ABSTRACT          Apparatus for cutting vegetables and food products into small Pieces The apparatus comprises a substantially cylindrical, vertical-axis container divided by a motor-driven rotary disc into upper and lower compartments.  A cutting tool is fixed to the disc for rotation therewith and extends above the disc itself from its central zone to the periphery. The disc and the tool are carried by a vertical shaft the end of which has means for coupling it to a drive shaft which projects upwardly from the bottom of the lower compartment.   A vertical duct in the upper compartment opens immediately above the path of the tool and products are introduced through this duct and pressed against the upper face of the disc to be cut into small pieces by the tool, to be minced, sliced, diced, chopped or shredded, according to the type of tool. The disc has an aperture for allowing the cut products to fall into the lower compartment.  At least an upper part of the shaft is constituted by a tool hub member which can be separated from the disc and which carries the tool, to allow the replacement of the tool itself without the need to replace the disc.            The shaft and the disc may be separate components and the disc may be keyed to the shaft so as to be slidable thereon.            Means may be provided for adjusting the position of the disc along the shaft in order to adjust the thickness of cut of the products.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention teaches an improved anvil plate for use with a surgical stapling instrument.  A magazine portion of the surgical stapling instrument houses the anvil plate terminating at its forward end in a coexten-sive anvil surface located beneath the staple driver, and the anvil plate is configured to support the legs of all but the forwardmost staple of a row thereof mounted thereon.  The improved anvil plate narrows the opening through which the forwardmost surgical staple is formed, and assures that the staple immediately behind the forwardmost one of the row will be in proper position for forming when it becomes the forwardmost staple in the row.  As well, this improved anvil plate gives better support to the forwardmost staple of the row being formed.

The synchronizing mechanism generates the operate signal upon sensing the readiness signals of all the devices and continues to generate the operate signal while at least one of the ready signals is sensed.  The synchronizing mechanism generates the stop signal upon sensing the completion signal from all of the devices and continues to generate that signal while at least one of the completion signals is sensed.

Abstract: ABSTRACT:          "Television signal encoder".     A television signal encoder for luminance and chrominance signals presented in digital form comprises luminance and chrominance channels in which the blanking and colour burst signals are inserted digitally before the signals are converted to analogue form for modulation and transmission.         The luminance signal is presented to a buffer circuit and during the line period the output of the buffer circuit is fed to a DAC via a highway under the control of an enable signal. During the blanking period a ROM applies a digital version of the blanking level to the highway. A ROM is enabled for a short period at the start and finish of the blanking period and is arranged as a variable multiplier to determine the slope of the blanking waveform. The output of the DAC is filtered and it is added to the modulated colour subcarrier signal and the synchronising pulse.         The chrominance channel is basically similar to the luminance channel but includes means for demulti-plexing the U and V signals and a further ROM for inserting the colour burst amplitude.  The U and V signals after filtering are fed to modulators to modulate the colour subcarrier signal.

Abstract: ABSTRACT OF THE DISCLOSURE:           Arctic berm for offshore structure foundation.          It is made of several ballasted ice slabs stacked one over the other and welded together to form a solid mass.  The berm is obtained by delimiting a uniform ice thickness area over landfast ice, area made up of a central rectangle and arms radiating from the central rectangle, each arm defining successive rectangles.  After all rectangles are ballasted sufficiently for them to sink when cut as slabs, one rectangle is cut into a first slab, is allowed to sink slightly and the rectangle next to it in one of the arms is cut and moved over the first slabs to be welded to it into a solid mass.  The remaining rectangles of the arms are, in turn, likewise cut and moved over the already piled slabs and welded to them until the berm is finally obtained.

At least one fuel cell, utilizes hydrogen, produces output electrical power at a second voltage and a second current.  A regulator supplies the hydro-gen produced by the electrolysis cell to the fuel cell for consumption of at least a portion of the hydrogen by the fuel cell.
