Abstract: ABSTRACT OF THE DISCLOSURE        A control console has a small and compact array of twenty-seven illuminable push buttons arranged in three continuous groups of nine each.  The buttons in the upper group related to anatomical arears in upper parts of the body, and the buttons in the lower group relate to areas in the lower parts of the body and the extremities.  The middle group are control and X-ray technic variation buttons. different anatomical regions are indicated by pictographs on the push buttons in an organized array in the upper and lower groups.  pressing at least one push button in the middle group and one in the other groups sets up and dis-plays the X-ray exposure parameters corresponding with the equivalent of the user's priority technic, including safe patient exposure and safe x-ray tube operating time, which has been stored in a memory, for the particular anatomical region.  The programmed values for tube kV,mA, mAs and time are displayed.  Controls are provided for enabling the user to dominate the programmed settings by overriding the stored values when professional judgement indicates.  The principal stored technic data values may be altered easily when and if experience with stored val-uses shows need for override within the normal range of patients of one or more of the principal technic parameters to accommodate an abnormal patient or medical condition.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method of producing lustrous to bril-liant zinc electrodeposits, which comprises passing current from a zinc anode to a metal cathode for a time period sufficient to deposit a lustrous to brilliant zinc electrodeposit upon said cathode.  The current passes through an aqueous acidic bath composition containing at least one zinc com-pound providing zinc cations for electroplating zinc.  The zinc compound is selected from the group consisting of zinc sulfate, zinc chloride and zinc sulfamate.  Chloride anions are added as salts of bath compatible cations excepting ammonium; in the absence of complexing or chelating agents of or-ganic nature; and containing, as cooperating additives, at least one alkyl propoxyethoxy polyether, at least one aromatic sulfonate emulsifying agent, and at least one aromatic carbonyl compound.  The zinc deposits made accord-ing to the invention are lustrous to brilliant, smooth, relatively ductile, low in internal stress, have low tarnishing tendencies and good receptivity to conversion coatings.

Title: Current limiting device for an electric power  system
Inventor: BARKAN PHILIP
IPC: H02H3/08
Filed: 1978-10-26
Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE This current limiting device comprises a normally-closed source-side circuit interrupter, a normally-closed load-side circuit interrupter, an electrical conductor connected between the interrupters for connecting the interrupters in series, and a normally-open switch that can be closed to connect the conductor to ground via a low-impedance conductive path located electrically between the interrupters.  A switch operator acts to rapidly close the switch in response to a fault on the power circuit extending through the series combination of interrupters, thereby connecting the conductor to ground through the switch.  The switch operator closes the switch within 1/4 cycle of power frequency current after fault inception, thereby effecting current-limiting action with respect to current through the series combination of interrupters on the load side of the conductive path to ground.    The interrupters are opened in response to the fault by the switch-operating means acting through a mechanical connection between the switch operator and the interrupters. Such interrupter-opening occurs sufficiently rapidly that the source-side interrupter interrupts the current therethrough at the first natural current zero following fault-inception.  An impedance connected in parallel with the series combination of the interrupters conducts current, limited in magnitude by the impedance, around the interrupters when the two interrupters have interrupted the currents therethrough following their opening.

Abstract: SEAL-FREE PIPETTE DEVICE                    ABSTRACT         A method and apparatus for measuring a predetermined relatively small volume of liquid from a supply liquid and subsequently dispensing that volume of liquid.  A long hollow tube having one end sealed is connected at the other end to an open-ended probe.  The long tube is curved into at least one C-shaped segment and is generally rigid along its entire curved length.          With the probe tip inserted into the supply liquid, the curved tube is flexed about an axis normal to the plane in which it lies, thereby decreasing the cross-sectional area of the tube.  Since the tube is generally rigid along its entire curved length, this flexure of the tube increases the internal volume of the tube thereby reducing the pressure within the tube and withdrawing liquid from the supply liquid into the probe.  The amount of liquid withdrawn into the probe is determined by the amount of flexure of the tube.  Flexure of the tube in the opposite direction causes the cross-sectional area of the tube to return to its original size thereby decreasing the internal volume of the tube and increasing the pressure within the tube which forces the liquid out of the probe.

Abstract: ABSTRACT OF THE INVENTION An optical storage medium in which the effect of optical interference is utilized to provide information storage. Heating of selected portions of the optical storage medium causes a permanent change in the wavelength and intensityof the interference fringes of the optical storage medium, and those changes give rise to large changes in light reflectivity at the initial interference fringe wavelengths, and hence gives rise to an optical pattern that is readily detectable. Preferred storage medium materials include alloys of the Ge-Se-S-Te group overlaying a metallic layer.

Davies ABSTRACT OF THE DISCLOSURE                The apparatus generates a train of pulse signals in real time which are fed to a Plan Position Indicator radar display video bright-up circuit.  A line is formed on the display at a bearing ?, the direction of a VHF/DF fix, and passes through a point having the coordinates R0, .angle. ?, the position of the VHF/DF receiver, with respect to the center of the  plan position indicator rotating radial scan.  The radial scan operates at a radar trigger pulse repetition frequency F and rotates at a frequency f to subtend an angle  ~ 9 - 360° x f  per scan.          The apparatus includes an up-counter for storing a count of   ROsin (? - ?), and a down-counter coupled to the up-counter and enabled at the pulse repetition frequency F to receive the count from the up-counter.  The down-counter is adapted to provide an output pulse signal to the video bright-up circuit when its count reaches 0.  A binary rate arithmetic multiplier has a first input which receives clock pulses at a frequency fc >> F and a second input which receives a digital binary signal that is a function of the radar pointing angle .theta.  of the radial scan.  The multiplier thereby provides a series of timed output pulses to the down-counter such that the down-counter counts down to 0 and triggers the video bright up circuit.
