Abstract: ABSTRACT OF THE DISCLOSURE   In order to facilitate construction of a compact, lightweight servoed accelerometer with capacitive pick-off, a one-piece support frame, adapted to be inserted within a cylindrical housing, is used to support a pair of capacitor plates and a lightweight longitudinally reinforced pendulum or seis-mic mass having a paddle on one end.  The paddle is positioned midway between the capacitor plates, thereby forming a pair of capacitors each having a capacitance on the order of 2 to 4 picofarods.  Attached to the pendulum is an axle which in turn is supported between two flexures by means of jeweled pivoted bearings.  The ends of the flexures are rigidly secured to the support frame, and a desired pressure of the bearings against the axle is maintained by means of adjustment screws.  Also attached to the pendulum is a torque coil which interacts with a magnetic assembly, secured to the support frame, to restore the paddle to the midpoint between the capacitor plates when the pendulum has been subjected to an acceleration force.  Secured to the support frame above and parallel to the pendulum is a thick film circuit board con-taining an integrated circuit and associated hybrid elements for applying time varying voltages to each capacitor so that the currents flowing through the capacitors can be used as a measure of the difference in capacitance due to deflection of the paddle; and in response thereto, generate sufficient current in the torque coil to restore the paddle to the midway point between the capacitor plates.  The circuitry also includes an output circuit having a servo-compensated network for applying a restoring current to the torque coil wherein the gain and frequency characteristics of the servo system are independ-ent of any impedance used to measure the restoring current.

Abstract: SUN-TRACKING SOLAR ENERGY CONVERSION SYSTEM                 Abstract of the Disclosure A number of solar energy converter assemblies are carried by a support frame which is mounted for independent rotation about a horizontal and a vertical axis.  Sensors detect the position of the sun; and control circuitry positions the support frame in elevation and azimuth so that the converter assemblies track and face the sun whenever the sun incident energy is greater than a threshold level of about 25 per cent of normal. Each converter assembly includes a solar cell and a multi-angular conical concentrator shell for collecting, concentrating and directing incident solar energy onto the solar cell.  The converter assemblies, the support frame and its mount, and the drive mechanism for the support frame are all located within a transparent stationary housing or enclosure, which provides complete environmental protection for all elements mounted within the enclosure.

Abstract: Abstract The invention is a commercial or lottery instant game played with a ticket which bears a pre-printed number for the lottery game and no number for the commercial game.  A random generated number is printed on the ticket for digit comparison with the pre-printed lottery number or digit sameness comparison of the printed random number on the commercial ticket.  Sensing of the ticket stops a random number generator with a memory holding the random number developed on stopping.  This number is printed on the ticket and displayed. In the absence of a ticket the device displays changing numbers as an attractive.          The ticket may be validated by sensing and encoded with special information.

Abstract: CHANNEL DATA BUFFER APPARATUS FOR A             DIGITAL DATA PROCESSING SYSTEM               Abstract of the Disclosure Channel data buffer apparatus for buffering data being transferred between an input/output channel unit and a main storage unit in a digital data processing system.  In the disclosed embodiment, data is generally transferred between the channel unit and the data buffer (a "channel/buffer" transfer) in two-byte seg-ments and between the main storage unit and the data buffer (a "storage/buffer" transfer) in eight-byte segments.  The data buffer is comprised of eight column-forming byte-wide multirow storage arrays each having its own address mechanism for accessing any desired row therein.  Corresponding rows in the different storage arrays provide the corresponding eight-byte rows for the data buffer as a whole.  For storage/buffer trans-fers, data buffer address circuitry is provided for enabling a group of eight contiguous bytes to be read out of or written into the data buffer on a single access even though some of the bytes may be located on one row of the data buffer and other of the bytes on the next row of the data buffer.  For channel/buffer transfers, data buffer address circuitry is provided for enabling a group of two contiguous bytes to be read out of or written into the data buffer on a single access even though one of the bytes may be located on one row of the data buffer and the other of the bytes on the next row of the data buffer.  For storage/buffer transfers, an eight-byte wrap-around data shifter is located between the data buffer and the main storage unit for enabling any necessary alignment or realignment of the data being transferred.  These features enable data to be loaded into the data buffer in a packed manner and without regard to the storage word boundary alignments in the main storage unit.  Among other things, this minimizes the hardware needed for buffering the data and improves the data chaining capability of the system.

Abstract: Spiral Pipe Forming Machine With Device For Aligning Spiralling Rolls Abstract of the Disclosure An improved apparatus for continuously forming spirally corru-gated metal pipe from an elongated sheet of metal which is first impressed with longitudinal corrugations in a corrugating device and then spiralled into a pipe in a three roll forming device, each roll of which is composed of a plurality of individual rollers.          Each individual roller is mounted for rotation about its axis in an individual roller yoke, with each of the roller yokes of each roll being in constant abutment, but with adjacent roller yokes being uninterconnected.  Individual roller yokes of each roll are posi-tioned along a guide, with each yoke being, both freely displaceable along the guide along a horizontal path generally parallel to the axis of the formed pipe, and also pivotable about a vertical center axis.  One of the rolls, termed herein a horn roll, is situated to contact the inner wall of the pipe as it is formed, while the other two rolls, respectively termed the lead and buttress rolls, are situated to contact the outer wall of the pipe.  A rigid frame member is attached to the corrugating device, extending from the corruga-ting device into the three roll forming device in contact with either end of each of the lead and buttress rolls.  The buttress roll is the farthest downstream of the three rolls and is adjustable on an angle to the vertical in order to vary the diameter of suc-cessive helical convolutions of the metal sheet, therefore varying the diameter of the pipe produced.  A downwardly depending adjustable nent arm is attached to an end roller yoke of the horn roll and slideably engages the rigid frame member.  When the corrugating device is pivoted relative to the three roll forming device, the rigid frame member automatically relocates the positions of each of the three rolls and adjusts spacings between center axes of adjacent rollers of each roll to assure that the individual rollers constantly and correctly align with the corrugations of the metal sheet as it enters the forming device and is spiralled into helical convolutions.
