Abstract: TAMPER-PROOF CANNULA SUPPORT ASSEMBLY     ABSTRACT           An assembly for supporting a cannula comprises a hub which supports the cannula and which includes a post portion which concentrically surrounds a section of the cannula adjacent to the hub.  The assembly also includes a cover which is attachable to the post portion of the hub to enclose the cannula.  The cover and post portion are coupled together by a "tamper-proof" connection which normally resists removal of the cover, and thereby attests to the sterile integrity of the needle.  The connection can be broken in response to the deliberate application of a predetermined rotational force by the user upon the cover and cannot thereafter be recreated, thereby serving as an outward indication that the sterile integrity of the cannula has been compromised.  Both the post portion and the cover remain physically intact, despite the breakage of the connection, to permit return of the cover when desired.

Abstract: ABSTRACT OF THE DISCLOSURE A valve body includes a passageway for the flow of fluid there-through. A valve member, such as a ball valve member, is positioned in the passageway for rotatable movement about a first rotational axis between an open position and a closed position to open and close the passageway.  An actuator orbits about the first axis to move the valve member between the open and closed positions.  A bent unitary valve stem extends between the valve member and the actuator.  A lower end of the unitary valve stem is aligned with the first axis and is connected to the valve member for rotation with the valve member. An upper end of the unitary valve stem is aligned with a second axis angularly displaced from the first axis.   A bearing assembly retained in the actuator connects the stem upper end to the actuator.  A bellows, bent to follow the curvature of the valve stem, surrounds the valve stem to form a primary pressure boundary hermetically sealing the valve stem.  A housing surrounds the bellows forming a second-ary pressure boundary with the handle and accompanying static and dynamic O-ring seals.  A lower end of the bellows is connected to the valve body.          An upper end of the bellows is connected to the bearing assembly which rotatably supports the bellows in the actuator.  The actuator orbits about the first axis to open and close the valve while the upper end of the bellows rotates about the second axis.   Turning the actuator transmits torque through the pressure boundaries without  applying torque to the bellows.

Abstract: Abstract A machine and a method for sequentially manu-facturing a plurality of reinforced substrates such as shoe uppers, comprising a powder deposition station wherein a stencil assembly applies powder onto an annular receiving belt, the powder being applied in a three-dimensional configuration  because of peripheral spacer means arranged on the cut-out between the stencil and the receiving surface.  The annular re-ceiving surface is empowered to rotate to an arcuate heating station where the powder is fused by heating elements arranged thereabove and therebelow.  The fused powder is then moved to a join and cool station where a substrate is pressed against the fused powder by a transfer means causing it to press againsst a chill plate therebeneath.  The shoe upper is lifted by the transfer means from the receiving surface after it has cooled, the transfer means rotating so as to remove the now reinforced shoe upper from the receiv-ing surface to enable it to be removed therefrom, and a subsequent shoe upper gripped therein for sub-sequent reinforcement thereof.

Abstract: "MULTIPLE TEMPERATURE LEVEL REGENERATION OF CO2 FROM PHYSICAL SOLVENT" To regenerate a physical solvent, loaded with sour gases, especially CO2 and H2S, the loaded solvent is treated with a stripping gas and/or is expanded to separate absorbed CO2 and the resultant solvent is subjected to thermal regeneration to desorb H2S. To reduce energy requirements during regeneration, the CO2 desorption is conducted on at least two different temperature levels, the second being for example 30-80.degree.C higher than the first, with the first being conducted, e.g., at about those low temperatures conventional to low temperature absorption systems.

Abstract: Abstract of the Disclosure Apparatus is depicted which enables the sampling of the phase angle of a modulated signal and manipulates the sample  signals to demodulate the same.      The apparatus is particularly adaptable for use in demodulating the I and Q channel signals of a zero IF receiver.  The system contains an angle sensing circuit which combines the I and Q channel signals in differential   form to produce a series of output signals of an angular range indicative of the present value of the instanteous phase. The signals from the angle detector are coupled to an octant decoder which operates to determine the particular octant that the angle is to be included in.  In the present system eight octants are used, each comprising 45°.  The octant decoder determines which octant the angle belongs in and assigns a predetermined angle value to that angle.      In one embodiment, the assigned angle values are 0°, 45°, 90°, 135°, 180°, 225°, 270° or 315°.  The value of the assigned angles are then sampled by means of a clock at a high frequency rate whereby the resultant pulses indicative of the angles are then processed as differentiated to produce an output signal indicative of the information content on the original signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A probabilistic learning system of the type that receives sequential input data and outputs sequences of recognized patterns includes an array of interconnected probabilistic learning elements of the type that receives sequences of objects and outputs sequences of recognized states, said array of learning elements being interconnected to have a number of input learning elements and a number of output learning elements.  The input data is partitioned between the input learning elements of the array so that the partitioned input data forms objects provided to the learning elements in an overlapping and redundant manner.  The output sequences of recognized states from the output learning elements are collected and combined to provide a sequence of recognized patterns as an output of the probabilistic learning system.        The reliability of the learning system is enhanced due to the overlapping and redundant nature in which the input objects are processed through the system and the time required to perform the system task is reduced through the use of parallel processing through the array.  Each element of the array provides a signal corresponding to a rating of confidence in the recognized states and this rating of confidence is fed back to the input of the element to cause the element to learn the recognized states when the rating of confidence exceeds a predetermined threshold level.  The rating of confidence is also provided to the inputs of prior elements in the array to cause the prior elements to learn their recognized states when the rating of confidence exceeds the predetermined threshold.
