Abstract: Abstract Primer compositions for adhering overcoatings derived from in situ polymerizations of uncured monomers onto inorganic substrates are disclosed.  These primer compositions when coated on a substrate and included in a layered structure comprise at least one non-amino- or non-amido-containing silane, at least one of certain metal esters, and preferably an acidic material.  The overcoatings are derived from epoxy and vinyl monomers which require a superior level of adhesion.  The primed and overcoated substrates of the present invention provide articles having protective or decorative surface layers.

Abstract: WILLIAM A. GETTIG LARRY E. SHOOK          MULTI-POSITION SWITCH                 ABSTRACT OF THE DISCLOSURE A multi-position switch includes a movable actuator rod projecting from one end of a housing and having a cylin-drical contactor disc within the housing displaceable into a plurality of radial positions to actuate a selected one or a selected pair of circuits as the contactor engages and radi-ally deflects adjacent ones of a plurality of resilient con-tacts arranged concentrically about the actuator rod.  The displacement of the rod and its disc is regulated by an en-circling control element provided with alternate radial crests and valleys.  Groups of adjacent contacts are electrically joined in series such that displacement of the disc into a control element valley axially aligned with any one group of contacts closes one circuit while displacement into either adjacent control element valley closes an alternate circuit involving two adjacent series of contacts.  An additional cir-cuit is regulated by either of two means including the axial depression of a handle on the actuator rod to close a circuit through the rod, handle and housing of the switch or alter-natively, by means of a trigger mounted exteriorly of the housing and selectively closing a separate contact switch assembly attached to the housing.

Abstract: CLOSURE PANEL HINGE          Abstract of the Disclosure The hinge for mounting a closure panel on a vehicle body includes a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot.  A panel bracket is mounted on the closure panel and has a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam arrangement.  A tor-sion bar has one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar tor-sionally biases the panel bracket and closure panel to a normal pivotal position relative the vehicle body.  The portion of the torsion bar mounted on a panel bracket extends slidably through the cam slot of the body bracket to define a second cam arrangement.  The first and second cam arrangements are arranged relative one another whereby upon pivotal opening movement of the closure panel, the closure panel is bodily shifted to avoid inter-ference of the closure panel with the vehicle body.

Abstract: COUPLING AN ELECTRICAL SIGNAL TO TRANSMISSION LINES    ABSTRACT OF THE DISCLOSURE           A dataset apparatus is powered by voltages extracted from electrical signals passing between the data terminal apparatus and the dataset by circuits com-prising a capacitor and diode combination.  The trans-mitter of the dataset includes capacitance isolation of the signal from the transmission lines by applying an oscillated voltage and an inverted oscillated voltage dependent upon the signal to capacitors in a first cir-cuit to charge the capacitors through a diode whereby the oscillating voltage causes the capacitors to discharge through a second path formed by further diodes to charge a pair of capacitors coupled across the transmission lines.  A second circuit of similar impedance to the first charges the capacitors to the opposite polarity.  The arrangement can handle high common mode voltages on the transmission lines. The receiver of the dataset inclu-des a doubly balanced resistance bridge network connec-ting the transmission lines to a differential amplifier, the circuit being balanced such that signals from the transmitter are not applied to the amplifier and also common mode signals are not applied to the amplifier.

Abstract: ABSTRACT      A temperature independent dosimeter is provided for measuring an amount of irradiation of a predetermined frequency.  A photodiode (24) operating in its photovoltaic mode is irradiated  with the irradiation to produce a signal that is amplitude-proportional to the amplitude of the irradiation.  The signal is converted by a pair of operational amplifiers (89, 96) to a plurality of pulses that are proportional in frequency to the amplitude of the signal.  The plurality of pulses is counted by a counter (20) and the irradiation is terminated when the count reaches a predetermined amount.
