Abstract: Shuttle Drive Assembly for Wrapping Apparatus Abstract A shuttle driving assembly including a shuttle rotatably driven on an opened support frame by drive roller assemblies carried by the frame. The drive rollers engage mating apparatus on the shuttle to pro-vide a positive and responsive power transmission therebetween.  A motor and brake set is provided on a base for driving the shuttle through the drive roller assemblies at a constant speed of rotation, and for rapidly accelerating, decelerating and braking the rotation of the shuttle.  The structure of the shuttle during assembly permits relatively high speed operation and reduces out of balance conditions.

Abstract: COMPLIANT CONTACT PIN            Abstract An electrical terminal pin adapted for engagement with a plated-through hole in a printed wiring board backplane.  The pin includes at least one end for receiving electrically conductive elements and an S-shaped compliant portion adapted and dimensioned to minimize deformation of the plated-through hole.  The compliant portion includes a transition section in which the S shaped cross section evolves from the square cross section of the end of the pin.  Because of the varying dimensions in the transition section, a smaller plated-through hole, which requires more "conditioning" than a larger hole, will be first encountered by a relatively stiffer part of the pin.  As a result, the tolerance required in the production of plated-through holes may be increased.

Abstract: ABSTRACT OF THE DISCLOSURE:         A turntable platter for record players, consisting of two layers one of glass and one of plastic, lying one on top of the other.  The plastic layer can be of a thermoplastic and/or thermosetting material such as polycarbonate, polyacrylic, polystyrene or the like. The glass guarantees flatness, rigidity and pleasant appearance of the platter, such features not always being obtainable from the already known metal platters, while the plastic, guarantees light weight associated with such material.  The glass-plastic combination in the turntable platter represents considerable progess in the particular industrial field as it guarantees the absorption of spurious vibrations, and secondly, optimum sound reproduction quality.  The glass and plastic layers can be joined together by means of adhesive or pushed together and can also be of different sizes and shapes.  The turntable platter can be provided with an upper layer, preferably less than one micron thick, of conductive material.

Abstract: ABSTRACT      The non-linear alternating current transducer in-cludes a current transformer core (14, 50 or 80) compris-ing a yoke (14, 50 or 80) for receiving a line conductor (20 or 110) and a secondary winding (22 or 86). The yoke (14, 50 or 80) has an air gap (19, 56 or 101-105) config-ured to provide a non-linear magnetic circuit response for changes in current through the line conductor (20 or 110).          The non-linear magnetic circuit response provides a loga-rithmic voltage output across the secondary winding (22 or 86). The current transformer (12) is used in a control cir-cuit (10) for sensing, monitoring and interrupting current in the line conductor (20 or 110) such that a trip coil is energized to open the circuit whenever current is sensed above a predetermined current.  Also, the logarithmic re-sponse provides for high gain at low currents and low gain at high currents so that a very uniform percentage-of-reading accuracy is obtained with a meter operating off of the secondary winding.

Abstract: HEAT RECOVERY MUFFLER               Abstract of the Disclosure A heat recovery muffler comprising an outer body and having an annular heat exchanger disposed within the body and spaced from the ends thereof. The heat exchanger is provided with a central opening and an exhaust gas inlet pipe is located within the central opening and spaced inwardly therefrom to provide an annular passage.  The downstream end of the central opening of the heat exchanger is closed off so that the flow of exhaust gas entering the muffler body through the inlet pipe will be reversed and is directed upstream.          The heat exchanger is formed with a plurality of tubes that provide communication between opposite ends of the body, and the exhaust gases, after being reversed in flow, then flow downstream through the tubes in heat exchange relation with a cooling medium, such as water, to cool the exhaust  gases and heat the cooling medium.          The cooled exhaust gases are discharged to the atmosphere through an outlet pipe in the downstream end of the muffler body.  A spark arrestor can be incorporated in the downstream end of the body to separate carbon particles or other particulate matter from the gas being discharged through the outlet pipe.

Abstract: ABSTRACT Apparatus for monitoring and storing heart activity signals is disclosed as including a data processor illustra-tively in the form of a digital microprocessor.  The monitoring and storing apparatus comprises a memory comprising first and second pluralities of storage locations, a circuit operating in a real time frame for sampling at a regular rate the patient's heart activity and for storing such sample signals in corres-ponding locations of said first plurality, and the data pro-cessor for processing the signals stored in the first plurality and for storing the processed signals in selected locations of said second plurality.  The storage of the signals in the second plurality is performed in a second computer time frame and at a rate faster than the real time sampling rate.  A sampling clock provides a sampling clock signal to the sampling circuit whereby the samples of the patient's heart activity are taken.  A second computer clock provides computer clock signals to at least a portion of the data processor whereby the processing of the heart activity is effected in the relatively fast computer time frame.  The data processor comprises a first portion or means that operates in response to the sample clock signal for evaluating the heart activity signals to determine the existence of a valid heartbeat and a second portion operating in the computer time frame for processing the detected heartbeat and in particular for determining the interval therebetween, which is evaluated to determine whether the heartbeat is occurring with a regular rhythm or not.
