Abstract: ABSTRACT NOISE AND CROSSTALK REDUCTION IN    ANALOG TO DIGITAL ENCODERS A reduction in idle channel noise and crosstalk in a mid-riser-biased successive approximation encoder is achieved through the use of two polarity decisions. Encoder (401) assigns a sampled analog input signal to the closest one of a multitude of discrete signal levels or code steps.  A comparator (109) provides this assignment by successive comparisons of the sampled signal with a series of reference signals (110).  Each comparison produces a binary digit. The first comparison, or polarity decision, is not transmitted and instead coupled to feedback circuitry (401) to reduce any d.c. component in the analog input signal to substantially zero.  A second polarity decision is then made using a non-zero offset reference signal (402) corresponding to an intermediate position on a code step, typically the midpoint.  The non-zero offset reference signal is applied along with subsequent reference signals to the comparator to determine the closest code step.  The binary digit from the second polarity decision, along with the binary digits representing the code step, are coupled to the encoder output.  Accordingly, the encoder is now biased at the intermediate position to substantially reduce the likelihood of idle channel noise and crosstalk enhancement.

Abstract: METHOD AND APPARATUS FOR SPIN BONDING ENDS    FOR COMPOSITE CONTAINERS, AND PRODUCT            ABSTRACT OF THE INVENTION           A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall.  The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove.  One of the body and end members is rotated relative to the other member when they are in spaced vertical alignment, whereupon the members are axially displaced together to wedge the upper end of the body member into the annular groove of the end closure member. During this  spin bonding process, the fin portion of the end closure member is supported against radial inward deflection, whereby the spinning frictional engagement between the fin portion of the end closure member and the inner liner layer of the body member causes softening and subsequent bonding of the fin portion to the inner liner layer.

Abstract: AMPOULE CRUSHER MECHANISM     ABSTRACT OF THE DISCLOSURE          Method and means for solidifying nuclear waste for permanent disposal are disclosed.  A storage container, in the preferred form of a drum or barrel, is charged with a predetermined amount of liquid polymer resin in an uncata-lyzed state.  Catalyst-containing frangible ampoules are also positioned in the drum with a rotatable mixer mechanism.  At a waste filling station, the mixer is rotated to break the ampoules so as to mix the catalyst and the resin.  The cata-lyzed resin is then mixed with added waste material to com-pletely encapsulate the waste prior to solidification of the resin.  Monitoring of the filling and mixing process is pro-vided by continually sensing the torque force being applied to the rotating mixer mechanism.  Where the waste is a dust-like, dry particulate material, dust control means and method are also provided.

Abstract: ABSTRACT OF THE DISCLOSURE         A valve structure is provided which can be opened and closed under operating conditions without any adjustment in conditions existing in the system in which the valve is an element.  The valve element can be turned with respect to the seat to provide for proper relation between the valve element and the valve  seat to grind one with respect to the other during the operating cycle.  The valve also includes a clutch having a radial acting trip overload that prevents the valve seat from being damaged during grinding which is effected by turning the valve through the clutch while moving the valve toward the seat during the closing cycle and produces a con-trolled grinding operation independent of pressure within the valve.         When the valve is operated in the opposite direction, the  clutch disengages  and the actuator mechanism encounters only the thrust forces during the opening cycle.  This allows the valve to be easily opened without overloading the system.

A conveying member, carried by the raft movably in vertical direction, is brought to be close to the bottom of the water body. A push tube, carried by the conveying member movably in vertical direction, is pushed into the soil layer on the bottom of the water body to desired depth, whereby the push tube carries along the prefabricated drain, provided with an anchor on its lower end, located therewith in. Thereafter, the push tube is pulled up, the strip drain remaining in its place in the soil layer by the aid of the anchor. The aim of the invention is to reduce the consumption of prefabricated drain material, to reduce the time consumed in the operation and to reduce energy consumption. The invention teaches to pull the push tube up above the lower end of the conveying member. Another anchor is affixed to the prefabricated drain by the aid of an affixing means, located on the lower end of the conveying member.
