Abstract: WINDSHIELD WIPER               Abstract of the Disclosure An improved windshield wiper is disclosed.          The wiper comprises an upper portion and a lower portion connected by a flexible neck portion.  The lower portion comprises a body, and a lip for con-tacting the windshield.  The body supports the lip and is connected to the neck portion.  Portions of the body in the areas below connection of the upper portion to supporting superstructure are laterally removed from the extremity of the body inwardly a predetermined distance.  Material is not removed from the lip or neck portion.  The removal of the material in these areas reduces support of the lip by the body in the removed areas to thereby reduce excess pressure concentrations in, and equalize pressure distributions along, the wiper lip in the vicinity of the connection of the upper portion to supporting superstructure when it is pressed into contact with the windshield by the supporting super-structure.

Abstract: ABSTRACT OF THE DISCLOSURE       A superheterodyne receiver comprises a high frequency amplifier, a local oscillator implemented by a frequency syn-thesizer including a phase locked loop, a mixer, an intermediate frequency amplifier, and an up down counter for providing data concerning the frequency division ratio of a programmable coun-ter in the phase locked loop.  The up down counter is responsive to a command signal from an upward scanning switch to make an upward counting operation and is responsive to a command signal from a downward scanning switch to make a downward counting operation, and is further responsive to command signals simul-taneously obtained from these switches to make a consecutive upward and downward countering operation, whereby a receiving channels are consecutively selected in the upward or downward direction in a fast scanning manner.  Preferably, a fast scann-ing operation responsive to simultaneous depression of the switches is stopped responsive to a receiving signal such as an intermediate frequency signal or a detected signal obtained when a broadcasting channel is selected.  A digital channel display is provided such that the data representative of the channel being selected obtainable from a control is transferred in a bit serial signal format to the display; pulses having a pulse width wider than a predetermined value are utilized for the pur-pose of data processing to eliminate adverse effects of noise.

Abstract: ABSTRACT OF THE DISCLOSURE         A control system is described for use in a web transport in which a web is advanced from a supply spool to a take-up spool by a pair of drive motors, the latter of which are actuated by a servo control.  The system includes a variable gain network which enhances the gain of the servo system at very low speeds without sacrificing system stability at higher speeds, and a circuit for adding a hold-back torque to the motor driving the take-up spool to smooth its rotation under low torque conditions.  In addition, the system includes a device for inhibiting the rotation of the spools when an operator has removed the web from the spools, thereby preventing the servo control from rotating the spools in an uncontrolled manner in response to inadvertent operator movement of one of the spools.

Abstract: ABSTRACT OF THE DISCLOSURE       A switching regulator generates controllable pulses from a primary d-c. voltage source and then smooths the pulses to form a d-c. output that varies according to the changes in the pulses. A reference voltage source establishes a d-c. reference signal that varies in magnitude with any variations in the magnitude of the d-c. output but with a substantially constant differential in magnitude between the reference signal and the d-c. output. A voltage or current sensor generates a signal that varies in accordance with changes in the voltage or current level of the d-c. output, and a comparator detects the difference between the reference signal and the signal from the sensor to produce a control signal that varies according to changes in the difference between the two signals.  The pulses that form the d-c. output are adjusted in response to the control signal to maintain the output at a regulated voltage or current level. An auxiliary internal power supply is provided for the reference voltage source and the com-parator and the current flow is returned through the reference voltage source and the comparator to the auxiliary internal power supply to minimize power losses in the reference voltage source and the comparator.  A predetermined d-c. dry voltage is superimposed on the d-c. voltage from the primary source and floats with respect to the reference signal and the d-c. output.
