Abstract: ABSTRACT OF THE DISCLOSURE          An antiskid traction device of the type which is engaged under a vehicle wheel to provide traction thereto when stuck in a rut.  This traction device is characterized by being constructed to prevent sinking thereof into the snow or mud under the wheel, and to prevent throwing thereof by the wheel.  This traction device comprises sections articulated one to another end to end, including a resilient tongue section adapted to act as a runner or ski under the vehicle wheel, by an intermediate section or portion engaging in the rut to provide traction therein, and by a traction section formed of expanded metal made wider than the tire to bear on the opposite sides of the rut thus minimizing sinking of the traction device.  The expanded metal has nodal points selectively bent upward and downward to produce traction projections and wheel guide projections at the top and cleats at the bottom.

Abstract: CIRCUIT AND METHOD FOR REDUCING POLARIZATION CROSSTALK   CAUSED BY RAINFALL BY SUITABLE MANIPULATION OF THE           SIGNALS PRIOR TO TRANSMISSION          Abstract of the Disclosure A circuit and a method are disclosed for reducing the effects of polarization crosstalk, at a remote location, when the polarization crosstalk is due to the interaction of two common frequency RF signals, caused by rainfall.  This reduction in the polarization crosstalk is achieved by suitable manipulation of the signals prior to transmission.  The present invention functions by applying circuitry, to the transmitter, for pre-distorting the two signals being transmitted by the transmitter circuitry. This pre-distortion is produced by introducing a controlled amount of coupling between the two signals.  This amount of coupling is controlled in magnitude and phase so as to ideally be equal in magnitude to, but 180 degrees out of phase with, the polarization crosstalk introduced by the transmission medium.  The ideal result is that the polarization crosstalk introduced during transmission of the signals is cancelled by the coupling introduced prior to transmission.  In the preferred embodiment, the magnitude of an RF signal originating at the remote location and received at the transmit location is used as the basis for controlling the amount of coupling introduced between the two signals prior to transmission.  As a general rule, the less the magnitude of the received signal, the greater is the polarization crosstalk, and the greater is the amount of coupling introduced between the two signals prior to transmission.  It should be appreciated that this is only an approximate correction scheme and will seldom, if ever, produce perfect correction.                             - i -

Abstract: CAM MECHANISM FOR IMPARTING             ORBITAL MOVEMENT TO THE BLADE OF                    A RECIPROCATING  SAW     Abstract Of The Disclosure The jigsaw has a drive gear carrying an eccentrically mounted drive pin forming part of a Scotch-yoke mechanism for reciprocating the blade holder along a first path.  Upper and lower bearing assemblies mount the blade holder for reciprocating movement along the first path and for pivoting movement; the lower bearing assembly is mounted for reciprocating movement along a second path transverse to the first path thereby to impart corresponding movement to the lower portion of the blade holder.  The drive gear has an annular concentric cam surface arranged for engagement with the lower bearing assembly.  A resilient member engages the blade holder for urging the lower bearing assembly against the cam surface to cause reciprocation of such bearing assembly along the second path whereby a saw blade attached to the blade holder will trace out an enclosed path.  An adjustment cam is provided to vary the stroke of movement of the lower bearing thereby to vary the shape of the path of movement of the blade.

Abstract: ABSTRACT          An agricultural machine, for example a rotary harrow, has a roller 10.  A pivotable protective member 13 extends over the harrow and the roller and is held in a raised position by a spring 22.  If the protective member 13 is pressed down, for example by the weight of a person falling on to the machine, a projection 16 engages rods 10A of the roller 10, so preventing further rotation of the roller.  At the same time, a linkage 18, 19, 20 causes an overload coupling 5 to be disengaged, interrupting the drive to working members 2 of the harrow.  The construction reduces the risk of injury to people coming into contact with moving  parts of the machine.  In other embodiments remote sensors are used to detect the presence of people too close to the machine. Further embodiments provide for the drive to the moving parts to be interrupted if the driver leaves the controls.

Abstract: ABSTRACT            There is provided a process for desupersaturation of supersaturated calcium sulfate solution which comprises injecting solutions into an inverted truncated sub-stantially conical reaction vessel proximate to the apex thereof.  Said vessel is provided with crystalline calcium sulfate, an entry port proximate to the said apex, an exit port proximate to the base and, in a preferred embodiment, a second exit port for the re-moval of excess calcium sulfate suspension.  The size of the vessel, the amount of calcium sulfate charged and the rate and volume of injected supersaturate are predetermined to provide intimate contact between the supersaturate and the calcium sulfate charged while providing a volume adequate to permit sufficient set-tlement of the upper portions of the thus formed cal-cium sulfate suspension  o that the treated waters may be drawn off at the top of said vessel through the first exit port in a form substantially free of suspended calcium sulfate.   The charged calcium sulfate provides seed cores for the crystallization of the dissolved calcium sulfate whereby the charged waters are desupersaturated.       A novel improvement in the otherwise conventional ap-paratus utilized, lies in the provision of a second exit port in the circumference of the vessel for the removal of calcium sulfate suspension to control the amounts thereof.  Such a second exit port is suitably located in the lower portion of the vessel but above its apex.
