Abstract: RECURSIVE-LIKE ADAPTIVE     ECHO CANCELLER            Abstract of the Disclosure The circuit complexity of a closed-loop echo cancellation system for use in a two-way communication circuit is reduced by employing a second adjustable signal processing network of the transversal type positioned in the control loop to emulate the characteristic of a recursive adjustable signal processing network.  The two signal processing networks in the control loop are adjusted simultaneously to effect echo cancellation.  The second signal processing network compensates for the effect of transmission poles in the echo return path and reduces the duration of the impulse response of the echo return path significantly so that the first signal processing network in the control loop is greatly simplified.  A third signal processing network of the recursive type is adjusted in accordance with the internal settings of the second net-work to perform signal processing inverse to that of the second network.  The recursive network is utilized to provide a clear signal path through the echo cancellation system which is essentially free of echo.

Abstract: ABSTRACT OF THE DISCLOSURE A microwave input circuit including a parametric upper sideband down converter for receiving an input signal whose frequency is not much different from the intermediate frequency produced at the output of the down converter.  The down converter may be either of the series type or of the parallel type and has its signal input directly connected to a microwave antenna and terminated by the real antenna resistance (Rg) or the real antenna conductance (Gg), respectively, at the input signal frequency (fsl). The parametric down converter comprises a cascade connection of a parametric down converter stage and a parametric up converter stage with both of said stages being of the series type or of the parallel type.  The down converter stage is terminated at its image frequency (fsp) with a real resistance (Rsp) or a real conductance (Gsp), respectively, and satisfies the following relation-ship for a series type down converter:       where Rsl is the series resistance of the reactance diode in the down converter stage, or the following relationship for a parallel type down converter:                     where GDl is the conductance loss of the reactance diode in the down converter stage, due to Rsl.

Abstract: ABSTRACT OF THE INVENTION       This invention relates to switch-proof labels useful for marking objects in a manner such that if one were to attempt to transfer the label to another object the label would be destroyed or defaced to such an extent that its transference would be noticeable.         The label comprises laminate comprising a trans-parent or translucent outer sheet having an information con-taining pattern printed on its inner surface, said printed inner surface having a coating of pressure sensitive ad-hesive film coated thereon.  The printed pattern has a lesser affinity for the outer sheet than the printed pattern has for the adhesive.  The affinity of the adhesive for the surface to which the laminated label is adhered and to the printed pattern is greater than the affinity of the printed pattern for the the outer sheet.         In a preferred embodiment the free side of the adhesive film of the label is covered by a release sheet.         Once applied to a substrate, if removal of the label is attempted, the label delaminates in a manner such that the outer sheet separates leaving at least a portion of adhesive layer, having at least a portion of the printed pattern adhering thereto, adhered to the substrate.

Abstract: ABSTRACT     Home building construction is characterized in a combination sidewall and roof extending from the building base to peak over the length of the building.  The combination sidewall and roof provides internally of the home a continuous surface on which a sheet of air-vapor barrier extends from building base to top over insulation material positioned between the rafters.  The connec-tion between the barrier sheets is essentially impervious to prevent moisture laiden air within the building migrating through the barrier.  A pair of support beams are fastened horizontally to the respective sidewall at normal first storey ceiling height to provide a two-storey building.  Each support beam has a barrier sheet affixed to its inside surface prior to installation.  The air-vapor barrier overlying the insulation is affixed to the air-vapor barrier on the beam at its top and bottom and is so connec-ted to provide an essentially impervious barrier to moisture laiden air within the building.

Abstract: FLOW CONTROL DEVICE FOR   AN IRRIGATION DITCH     ABSTRACT OF DISCLOSURE         A device for controlling the flow of water between an irrigation ditch and an adjacent field.  A conduit having a first end opening into the irrigation ditch and a second end opening into the field to be irrigated.  The cover is pivotally attached to the first end of the conduit by means of a "J"-shaped hinge.  A handle is provided on the exterior of the cover and can be engaged by a manually-held instrument to pivot the cover to a position above the conduit where it will rest due to the configuration of the hinge part.  The conduit is positioned relative to the irrigation ditch such that the first end is recessed inwardly of one side wall of the ditch and extends below the bottom wall of the ditch.           This invention relates to a device for controlling the flow of water between an irrigation ditch and an adjacent field.       Many prior art devices for controlling water flow between an irrigation ditch and an adjacent field include external means for actuating cover plates or valves usually in the form of linkages or other protrusions which extend above the ground surface or along the side walls of the irrigation ditch thereby interfering with machinery traversing the banks of the ditch or machinery used to clear and plow the ditch.

Abstract: ABSTRACT OF THE DISCLOSURE      Folding structures useful for a variety of different utilitarian and play purposes can be constructed so as to utilize a Sarrus linkage modified so as to include an overcenter toggle mechanism to reinforce the linkage against inadvertent or undesired folding from an expanded position. As used in accordance with the invention such Sarrus linkage includes two non-folding members or walls which are connected by two separate folding wall structures.  Each of such wall structures includes two non-folding parts, an intermediate hinge connecting such parts, and edge hinges connecting such parts to the non-folding members or walls.  At least one of the connecting wall structures is formed so as to serve as an overcenter toggle which is capable of holding the two non-folding members or walls in the expanded position while the other of the connecting wall structures serves to limit the movement of the non-folding members or walls away from one another so as to serve the apply pressure on the connecting wall structure serving as the toggle.  The folding structures of the invention are useful as various different types of play equipment but are considered to have other utility.
