Abstract: METHOD AND APPARATUS FOR MEASURING ROLL GAP   AND ALIGNMENT FOR CONTINUOUS CASTERS     Abstract of the Disclosure Strand-like apparatus for measuring roll position, i.e., roll gap and/or roll alignment, is moved through a caster between roll faces of a series of oppositely spaced pairs of conveyor rolls which define either a straight or curved strand travel path.  Apparatus includes carrier means having resiliently deformable parallel sensing surfaces with an elastomeric core, and plural lateral and plural diagonal inductive distance measuring means pivotally linked to the sensing surfaces for generating roll gap and alignment signals.  These signals are recorded.  Single and multiple harness means attach single and multiple measuring apparatus to a powered starter bar at one or more lateral strand axes, thereby to make lateral roll position measurements during multiple or single passes, respectively.

Abstract: PROGRAMMABLE RINGING GENERATOR                 ABSTRACT OF THE DISCLOSURE     An apparatus for generating a selected one of a plurality of ringing frequencies utilizing a single frequency source.  A first counting device is utilized to divide the source frequency by a first predetermined integer to generate a series of address signals at a rate proportional to the selected ringing frequency.          A read only memory is responsive to the address signals for gen-erating a series of values representing points along a sine wave form such that, as the first counting device continuously cycles to a maximum count total equal to the number of values stored in the read only memory, the sine wave form is repetitively generated.          If the source frequency is not an integer multiple of the selected frequency, the first integer is selected to generate the closest higher frequency and a second counting device is utilized to increase the time required for the first counting device to generate all of the address signals for one-cycle of the sine wave form.  The second counting device divides the first counting device output frequency by a second predetermined integer to generate signals to disable the first counting device for at least one count each.  The second integer is selected to obtain the number of missed counts of the first counting device which will result in an actual cycle time as close to the selected cycle time as possible.

Abstract: ABSTRACT           A ranging apparatus is provided having an encoded waveform signal which is generated by completely random se-quence generator without second order statistics so that the waveform signal is not capable of being analyzed.  The modulated radio frequency waveform is transmitted to an object and the reflected signal is received by the ranging apparatus which comprises a digital solid state read-write memory arranged to have information written into the memory at a fixed frequency and arranged to have the information read out of the solid state read-write memory at a variable frequency to provide the equival-ent of a rotating memory.  The digital logic employed in the ranging apparatus is extremely accurate and not subject to drift and changes which could occur in analog type systems.          The implementation of the ranging apparatus is accomplished with economical commercially available components thus providing an improved digital ranging apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE     In a system for producing an operating signal for, for example, opening a lock in, for example a bank, there are included a central data processor and a terminal carried by a guard.  The terminal is provided with a code transmitter including a code which is unique for the unit in question, this code being set to the data processor from the terminal together with a code personal to the guard.          If the data processor accepts the received code upon compari-son with stored information, the random signal generator transmits a random code signal to the unit and to the ter-minal.  The random code signal is transmitted from the ter-minal to a code receiver in the unit, and the two random code signals received cause the operating signal to be generated.

Abstract: ELECTROTHERMAL MATRIX ADDRESSABLE LIQUID CRYSTAL DISPLAY          Abstract A row and column matrix of strip electrodes is utilized for switching bistable liquid crystal display cells from the vertical state to the horizontal state via resistive heating by applying an electric current of sufficient magnitude and duration to selected electrodes. Resistive heating causes the liquid crystal to undergo a phase transition from the nematic mesophase to an isotropic phase.  Extinction of the current permits the liquid crystal to cool preferentially into the horizontal state of the nematic mesophase.  Horizontal-to-vertical state switching is performed by conventional electric field effect techniques.  (Fig. 6)

Title: Contact assembly for a high-voltage circuit interrupter
Inventor: LIN CHESTER H
IPC: H01H1/38
Filed: 1983-09-30
Granted: 1986-01-07
Abstract: ABSTRACT OF THE DISCLOSURE A female contact of an interrupter includes a number of flexible fingers in a cylindrical array defining a cavity toward the axis of which the fingers are biased. A pair of semi-annular refractory members are located at the free ends of the fingers and define a passageway which is continuous with the cavity. The members are not welded or brazed to the fingers and are, accordingly, transversely free-floating relative to the fingers; they can move laterally of the axis indepen-dently of the fingers, but are prevented from movement along the axis. When a male contact is out of the cavity and the passageway, the fingers act against the exterior of the members until facing stop surfaces on the members abut, setting the minimum size of the passageway, which is smaller than the diametric size of the male contact but larger than the diametric size of the cavity between contact buttons on the fingers. When the male contact is in the passageway, the stop surfaces separate and the fingers bias the members so that the wall of the passage-way intimately, slidingly engages the male contact. When the male contact is in the cavity the buttons intimately engage it, and outward flexing of the fingers disengages them from the members.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for measuring the peak amplitude of an input signal in-cludes a comparator for comparing the input signal against a reference signal. The comparator selectively drives a latch which in turn drives a successive approximation register.  The count in the successive approximation register is selectively increased or decreased by a predetermined amount, depending on the condition of the latch and the count in the register.  The register count is converted by a digital-to-analog converter to provide the reference signal.
