Abstract: Abstract:          Printing apparatus uses a daisy type print wheel which is continously driven through a magnetic clutch arrangement.   Characters are selected by actuation of either an electro-magnetic brake acting on the print wheel or a toothed character selector acting on the spokes of the print wheel.          When a character is selected and the print wheel is stopped, rotation of the motor continues because of the slippage of the magnetic clutch. Other features of the invention include a fast recovery time for the hammer because  of its constant rate of actuation, proportional spacing by varying this constant rate and also an improved carriage scan technique which provides for fast return.

Abstract: Abstract of the Disclosure A collar for controlling thermal and mechanical stresses and for reducing failures caused by such stresses in gas-transfer tubings, or pigtails, used in a steam reformer. The control collar, in the form of a section of tubing and having the same alloy composition as the pigtail, is placed over each end portion of the pigtail connected to an extension member attached respectively to a catalyst tube in the steam reformer and to a gas-removal manifold.  The control collar fits closely over the pigtail and is welded to the extension member.  Use of the same alloy composition in the pigtail and in the control collar eliminates stresses associated with differences in thermal expansion and con-traction, and the use of the collar reduces mechanical stress fatigue by displacing the point of maximum bending movement from the area of mechanical stress concentration of the weld, and the metallurgical notch in the heat-affected zone of the weld.

Abstract: A VIBRATORY MECHANISM              Abstract of the Disclosure According to the depicted embodiment, two eccentric-weight units are rotated into or out of radial alignment with each other to cause an increase or diminution of vibration.  The units are journaled in a frame and a coupling assembly causes both to rotate in unison, but the assembly is also operative to rotationally index one of the weight units relative to the other to vary the noted radial-alignment relationship, as desired.  One of the weight units comprises a pair of separate weights, each having an eccentric-throw portion, which are separated along the rotation axis and which are joined for common rotation by a resilient coupling.          The latter coupling sustains and reactively absorbs any mis-alignments and/or displacements arising between the separate weights.  The other weight unit is an elongate, eccentric shaft coaxial with the separate weights.

Abstract: SELF-ADJUSTING ELEVATOR LEVELING APPARATUS AND METHOD     ABSTRACT      A first memory contains the location of each floor in the elevator shaft.  A second memory stores a distance correction for each floor.  The sum of the stored correc-tion and the stored location is compared with the actual car location in the shaft to position the car at a floor.          Each time the car door opens, after a delay, the leveling distance is sensed and if the car is below a preselected level zone one unit of correction equal to a preselected distance is added to the stored correction.  The result-ing new correction is stored in the second memory.  On a successive stop at the same floor the car will position that preselected distance closer to the level zone until it is above the zone, when a unit of correction is sub-tracted from the stored correction.  In this fashion the car clusters around the level zone.

Abstract: ABSTRACT OF THE DISCLOSURE     An accurate frequency to voltage converter for cardiac telemetry systems, in which converter charges are stored in response to selected intervals proportional to the period of an alternating input signal.  Linearization of the output voltage as a function of input frequency characteris-tic is effectively and inexpensively achieved by charging charging and voltage holding capacitors from a substantially constant voltage through a resistance such that capacitor terminal voltage rises as an exponential function of time. The reciprocal function of frequency as a function of period has a similarly shaped characteristic curve, and these function characteristics are effectively combined by the invention to generate the desired linear overall conversion function.  Additionally, a controlled switching means is employed for alternately establishing a pair of signal path conditions, and this switching means has a definite internal ON resistance which prevents complete discharge of a charg-ing and voltage holding capacitor in the time allowed.  To alleviate a conversion inaccuracy which would accordingly otherwise result, an additional charging capacitor is connected directly to a means which periodically discharges capacitances.
