Abstract: ROGERS, BERESKIN & PARR             C A N A D A     TITLE     :  CLAMP-ON AMMETER        INVENTOR  :  AURELE BLAIN     ABSTRACT OF THE DISCLOSURE          A clamp-on ammeter for measuring current flows in a conductor is described.  The ammeter is of a type comprising a magnetic core which can be located about a conductor  and an indicator which responds to the magnetic flux consequently generated in the magnetic core to produce a signal indicative of the magnitude of the conductor current.  Means are provided for restoring the magnetic core to a predetermined magnetic state for each measurement.   The resetting means include a coil wound about the core and a coil energizing circuit which can be activated to produce in the core a residual magnetic flux substantially identical to that produced in the core when unmagnetized by a DC conductor current of predetermined magnitude, which represents the maximum value of any DC current which can be measured by the ammeter.  The ammeter includes another coil and energizing circuitry which then produce in the core an offsetting magnetic flux equal in magnitude but opposite in direction to the residual magnetic flux, thereby eliminating any offset which would other-wise be generated by the indicator in response to the residual magnetic flux.  To adapt the ammeter for AC measurements, another coil is wound on the core and is electrically shorted when the magnetic flux cutting the windings of the coil changes direct-ion from that of the residual magnetic flux.  The shorting of the coil tends to reduce the magnitude of the magnetic flux in the core to substantially zero.  By emplying an indicator responsive to a time average magnitude of the core magnetic flux a signal indicative of the magnitude of an alternating current carried by a conductor is produced.

Abstract: ABSTRACT OF THE DISCLOSURE     Ground-effect vehicle having the general shape of a snow-mobile, comprising an open front portion communicating with a rear-wardly- and downwardly-extending air duct, the latter being located directly under the driver's seat.  An air propeller located within the upstream end of the air duct, draws air from the open front portion and propels it downwardly to create a partial ground air-cushion and rearwardly to create a rearward air-thrust.          Rear skate rudders provide directional control of the vehicle, while brake plates control the vehicle speed by applying  friction on the ground or in water.  An alternate model includes an upwardly-strutted delta wing to allow flight of the vehicle.  Another model includes a suspension consisting of two elongated flexible tubular chambers at each lateral bottom portion of the vehicle.  An air channel inflates the chambers with air coming  from the propeller.          Stabilizer arms within the chambers prevent lateral deformation of the same due to centrifugal force during turns.

Abstract: Abstract A system for varying the vibration generating force of a rotating eccentric weight by providing a second weight movable from a position on one side of the axis of rotation of the eccentric weight to a second position on the opposite side of the axis of rotation, the movement being linear and radially across said axis of rotation.  In addition, a spring may be employed to move the movable weight toward the second position ini-tially, in compression, and later to resist additional movement in said direction, in tension, so as to provide basically a linear system for varying the vibrational force.  Fluid pressure may be applied to the movable weight which pressure will combine with the tension in the spring to move the movable weight against centrifugal force and toward the axis of rotation of the wheel.  Once the center of gravity of the weight passes the axis of rotation, further fluid pressure on the movable weight will act against the compression of the spring and will combine with the centrifugal force to move the movable weight radially outward from the axis of rotation.

Abstract: ABSTRACT            Apparatus and method for producing qualitatively high-grade color images of originals such as copy masters for multi-color or process printing by exposing chromatic material wherein the originals are scanned point-by-point and line-by-line and the color signals thus obtained are converted into color density values for the chromatic material by means of a correction of color and of gradation.          The drive values for a color exposure unit which exposes the chromatic material point-wise and line-wise are generated from the color density values using a linearization process.  As a result of signal inversion color positive originals can be recorded as color negatives and vice versa.  The exposure process can be matched to every chromatic material independently of the nature of the original to be reproduced and the state of the developing process by means of changing the color density values according to an arbitrarily selectable correction function and by means of signal inversion.
