Abstract: ABSTRACT      A high performance video clamp and self-balancing inverter circuit for providing the DC coupling of a video signal together with substantially perfect inversion of any portion of a composite television signal.  Under the control of synchronously timed pulses, two switches are alternately turned on and off to selectively apply the video signal to either the inverting or non-inverting input terminal of a  video amplifier, thus separating signal portions selected to be inver-ted from those portions selected to remain non-inverted.  To ensure perfect balance between inverted and non-inverted output signals, prior to processing, at least two reference pedestals are added to each field of the composite video signal to raise selected blanking level portions thereof to a level equal to 50% of the reference white level.  When received, each pair of reference pedestals is separated via activation of the switches so that, at the output of the  video  amplifier, the first pedestal appears as a non-inverted signal and the second pedestal appears as an inverted signal.  A selectively switched, negative feedback control system samples these respective output signals and derives an error signal of such polarity that the DC levels of both reference pedestals are balanced at precisely 50% of the reference white level.  Selective activation of a keyed clamp, which completes the feedback loop, clamps the video signal to this 50% reference potential, thus assuring constant balance between inverted and non-inverted portions of the output signal, regardless of input video signal changes.

Abstract: ABSTRACT In an electro-optical measuring system which utilizes a sin/cos signal pair to determine the extent and direction of physical displacement, measure-ment errors often occurring as a result of extraneous DC level shifts in generated signals are corrected in a procedure which regularly samples the maxima and minima of the signals, derives from those values the median DC levels of the signals, compares the median levels to a reference DC level in the system to determine any differences, and applies any detected differences as corrective factors to position measurement signal values.

Abstract: Lay-In Lug With Conduction Pad Abstract A lay-in lug to be coupled to a bushing, or the like, for providing a low resistance grounding connection between a wire secured in the lug and the bushing. The lug comprises a body member and a conduction member for providing strength and a low resistance conduction path, respectively. The body member supports the conduction member and includes resilience to compensate for cold flow of the laid-in wire. The conduction member is in direct contact with both the laid-in wire and the bushing to provide superior conduction between the wire and the bushing. In addition, the wire is pressed against one side of the back portion of the body member and the reverse side of the back of the body member is in direct contact with a back section of the conduction member. Although the conductivity of the body member is not as good as that of the conduction member, the resistance through the back of the body member between the wire and the back of the conduction member is not large due to the fact that the path is short and the cross-sectional area is relatively large. The body and conduction member are fabricted with appropriate proportions and angles to encourage controlled deformation of the conduction member as the lug is attached to the bushing and to assure improved conduction of the combination and good support for the conduction member.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a permanently attachable fitting adapted to be secured to the end of hose or tubing for the conveyance of fluids by compressing the hose or tubing wall within an annular space provided between a shell and nipple of the fitting by a process, such as swaging, that both contracts the shell radially inwardly against the hose or tubing wall and exerts a longitudinal compressible force upon the shell.  The shell wall has one or more annular bridges provided by annular grooves that are caused to buckle during the contraction process so as to reduce the elongation of the shell and reduce the relative longitudinal movement between the shell and the nipple and thereby improve the integrity of the hose or tubing wall within the fitting by reducing the amount of stretch and shear stresses imposed thereupon.

One member carries a resilient seal which has an annular lip inclined radially inwardly and axially toward an axially facing annular sealing surface on the other member. When the members are coupled, the lip flattens against the sealing surface to form a seal between the members and, in this condition of the parts, the resiliency of the lip also produces a force which keeps the bayonet-type connection in the locked position. When the members are being coupled while water is running through the member with the seal, an annular groove in the sealing surface causes water to backwash and clean the sealng side of the lip as well as the sealing surface itself,
