Abstract: LASER MICROFILM RECORDER        ABSTRACT OF THE DISCLOSURE    An optical printer system for producing microfilm hard copy from information signals presented at a high data rate.  An entire frame of information is printed line-by-line, each line being recorded character-by-character, each character being recorded column-by-column from a potential M-by-N matrix array by sweep-ing a column of M selectively actuated narrow beams of coherent light derived from a single laser source transversely of the film and successively repositioning the column in the longitudinal direction.  A transverse position detector provides precise positioning signals for initiating generation of successive characters so that each character is precisely positioned on the film within an accuracy of the width of a single beam column space.  A form image is projected onto the film at the end of a complete frame of characters.  The accuracy of character positioning provided by the system ensures character alignment with the form image.  The intensity of the character formation beams per-mits the use of dry process photographic film.

Abstract: .angle.                            ABSTRACT In the automatic conveyor system for conveying corrugated cardboard sheets from a sheet making machine, the sheets are delivered to a right angle roller conveyor to change the direction of the travel of the sheets at right angles to the delivery from the sheet making machine; a transfer conveyor receives the sheets from the right angle conveyor and transfers the sheets to a stacker conveyor at the stacker end of which latter the sheets are stacked. A back-up aligning device facing toward the direction from which the sheets are delivered from the sheets making is adjustable in accordance with the size of sheet. Above the transfer conveyor is a snubber with pre-determined relation to the sheets thereon, and means are provided to adjust the snubber conveyor also in accordance with the size of the sheets. At the stacker end of the stacker conveyor are back-stops against which the sheets abut to be aligned in the stack. Means are provided for adjusting the distance of the back-stop from the stacker end of the stack or conveyor in accordance with the respective dimension of the sheets. At the stacker end of the there are also aligning means provided for the side edges of the sheets and means are provided for adjusting the distance between the side aligners on the side  to the back-up alignment, also in accordance with the respective dimension of the sheets. A sensor at each of the ad-justing means is connected into a circuit whereby the device is set to the respective dimensions of the sheet and in one operation through this electric circuit all the aforesaid adjustable devices are adjusted and set to conform to the respective dimensions of the sheets. A safety device at the stacker end of the stacker conveyor automatically stops the operation of the stacker conveyor should the back-stops accidentally lower on  the top of the stack or on some person.    The circuits connected through an instrument board whereby the circuits are adjusted to preset the entire system to a sheet size then to operate the whole system for adjustment to the respective dimensions of the sheets.

Abstract: PROGRAMMABLE CONTROLLER WITH  PROGRAMMABLE I/O SCAN RATE     Abstract of the Disclosure A programmable controller sequentially executes a control program at a basic "scan rate" determined by the length of the program and the speed at which the controller processor executes the instructions therein.  At the completion of each scan through the control program an I/O scan is performed which inputs the status of all sensing devices to the controller image table and outputs status data from the image table to operating devices. The present invention enables the status of selected sensing devices to be inputted and acted upon at any point during the scan through the control program and it enables the output of the processor logic unit to be coupled to a selected operating device at any point.  The rate at which selected I/O devices can be scanned by the controller is thus programmable and may be much higher than the basic scan rate of the controller.

The compartment is generally cylindrical in shape having an access opening there-in, and the compartment is pivotally mounted on a frame located in the machine.  A currency dispenser located in the machine dispenses currency into the compartment upon command from a valid customer of the machine.  An arcuately shaped door panel normally closes the opening in the cabinet.  To dispense the currency requested by a valid customer, the compartment with the currency therein is unlocked and is rotated to align the access opening of the compartment with the opening in the pro-tective cabinet, and the compartment is locked in the dispens-ing position, and thereafter, the door panel is unlocked and is rotated to an open position permitting the customer to reach into the access opening of the compartment to withdraw the currency he requested along with an associated transaction receipt.  After a predetermined amount of elapsed time, the user access compartment is closed by first closing and locking the door panel in the closed position, and thereafter, the compartment is rotated in the opposite direction to dump any contents remaining therein into a special collecting bin located within the machine.

Abstract: METHOD AND APPARATUS FOR SEISMIC GEOPHYSICAL EXPLORATION                      Abstract of the Disclosure A method and apparatus for seismic geophysical exploration is disclosed wherein the seismic exploration system includes a seismic energy source, a central recording and control station, a plurality of geophones, and a plurality of remote geophone monitoring means.  The central control and recording station is coupled to the plurality of geophone monitoring means by a two-way radio frequency (RF) link.  The central recording and control station interrogates the plurality of geophone monitoring means by means of the two-way RF link to thereby determine the operating status of the plurality of geophone monitoring means.  The operational status of the plurality of geophone monitoring means is transmitted from each of the plurality of geophone monitoring means via the two way RF link to the central recording and control station in response to a specific address for each of the plurality of remote geophone monitoring means.  After it has been determined that the plurality of remote geophone monitoring means are operational, the central recording and control station initiates operation of the seismic energy source.  The reflected energy imparted into the earth by the seismic energy source is detected by the plurality of geophones.  Apparatus contained within the remote geophone monitoring means, associated with particular geophones, samples the signals detected by the geophones and produces representative data in digital form.  The digitized data is stored in a memory contained within the geophone monitoring means and is transmitted on demand to the central recording and control unit.  Error detection and retransmission of data from the remote geophone monitoring means to the central recording and control station is utilized to increase the reliability of data transmitted by means of the two-way RF link which couples the central recording and control station to the plurality of remote geophone monitoring means.

Abstract: PROCESS FOR CONTINUOUS CASTING OF A SLIGHTLY DEOXIDIZED STEEL SLAB             ABSTRACT OF THE DISCLOSURE        In the continuous casting of steel, it has been possible to produce killed steel industrially, but semikilled and rimmed steel have not been successfully produced due to rimming action occuring in the oscillating mold.  The present invention involves a concept of suppressing the nuclei of bubbles which will later grow into CO bubbles.  In order to suppress the nuclei of bubbles and to form a non-defective solidification layer of a continuously cast strand, the present invention provides a combination of:  a free oxygen concentration of from 50 to 200 ppm in the molten steel; a concave shape at the short sides of the mold; a propulsion forces of the molten steel directed along the long sides of the mold in directions opposite to one another; subjecting a solidification interface to an electromagnetic flow having a speed of from 0.1 to 1.0 m/sec, and; solidifying the molten steel at the solidification interface under the influence of the electro--magnetic flow, until a non-defective solidification layer without blow holes is obtained.
