Abstract: ABSTRACT OF THE DISCLOSURE     A graphic forms overlay apparatus to be used with non-impact printers requiring the use of a movable light sensitive medium such as laser printers is disclosed. Laser printers use a sweeping laser beam and a movable light sensitive medium to image data from a data processing source for printing.  A graphic forms pattern is overlayed on the data imaged on the light sensitive medium for simultaneous printing of the data and pattern.  To accomplish this a negative of the pattern is mounted on a hollow rotatable forms drum, and inside the drum a fluorescent tube is fixedly mounted for illuminating the negative. A linear portion of the light image of the negative formed thereby is reflected by an optical system of lenses and mirrors onto adjacent linear portions of the light sensitive medium being swept by the laser beam for imaging of data.  Synch-ronism between rotation of the forms drum and information being written on the movable light sensitive medium is provided by logic circuitry connected between the printer and a stepping motor which is coupled to the forms drum for rotation of the forms drum.  A top of page signal from the printer cooperates with the logic circuitry  to start synchronous rotation of the forms drum.  An alignment signal from an alignment means within the overlay apparatus cooperates with the logic circuitry to stop rotation of the forms drum in an initial position ready for the next top of page signal. Adjustable counter circuitry provides a means for externally varying the rotational speed of the forms drum.

Abstract: ABSTRACT          In manufacture of a can body by drawing a cup from a blank and subsequently redrawing the cup, one or more redrawing steps are performed by pulling the sidewall of the cup (2) by means of a punch (12) through an S-shaped path (30,24,31), whereby the wall is bent first in one direction and then in the other, to reduce its diameter, which is then reduced further in a convergent portion (20) of the die (10).  The bending induces back tensions which stretch the metal and reduce its wall thickness.

Abstract: STEPPED SCANNER IMAGING SYSTEM               Abstract of the Disclosure An imaging system includes a radiographic camera, a bed for supporting a subject in view of the camera, and a display.          The camera provides X and Y coordinate signals of each radio-graphic event.  The position of the bed relative to the camera is altered sequentially between each of a sequence of images provided by the camera.  The sequentially occurring images are presented on the display, each image being positioned on the display in correspondence with the location of the bed relative to the camera.  The coordinates of each image point presented on the display is equal to the sum of the respective X and Y coordinate signals from the camera with X and Y coordinate sig-nals defining the location of the bed relative to the camera.          The camera is electronically decoupled from the display during a movement of the bed relative to the camera from one location to the next location to prevent a smearing effect and a zippering effect within a composite image presented on the display.

For that the words are stored in a random access memory as they arrive, they are read at the frequency of the local clock and the filling rate of the store is permanetly determined. A comparator compares this rate with a given range. If the filling rate is greater than a maximum threshold or less than a minimu threshold, the contents of the memory are modified at the first silent interval which appears.

Abstract: ABSTRACT OF THE DISCLOSURE          This  application deals with the discovery of a highly effective new flame retardant, ammoniumtriborate (NH4-B3O5-3 CH3-OH).  Tetraborate ores, when treated in a warm methanolic suspension with ammonia and sulfur-dioxide (or ammoniumsulfite), undergo a three-step transformation.  First, through a displacement reaction, ammoniumtetraborate [(NH4)2?B4O7?4H2O]   and alkali metal or alkaline earth metal sulfite  are obtained.  As a second step, ammoniumtetraborate spontaneously loses ammonia and transforms into a new compound, ammonium-triborate (NH4?B3O5?3 CH3-OH).   The third step of this reaction series can be initiated by water and heat treat-mint of ammoniumtriborate which undergoes a molecular change to ammoniumpentaborate (NH4?B5O8?4 H2O). Parallel with these main reactions, a side reaction also takes place and methylborate-ammonia adduct [(CH3O)3B?NH3] is formed in low yield (<5%).  Upon water treatment, however, the said adduct also stabilizes in the form of ammonium-pentaborate.  The methanolic filtrate, its concentrate or freshly prepared water solution of the newly discovered ammoniumtriborate is useful as a very effective flame retardant, anti-smoldering, non-corrosive and fungal resistant agent when appropriately applied on cellulosic fiber insulation material, cotton batting, carpeting, furniture padding, upholstery and other natural or ABSTRACT (continued) synthetic fibers which are subjected only to dry launder-ing.  The presence of small amounts of inorganic or organic sulfites (<5%) improve the results of some flame retardation tests and anti-corrosion properties of said ammoniumtriborate and ammoniumtriborate-ammoniumpenta-borate mixtures.  The latter effect is due to the reducing (anti-oxidant) properties of sulfites.  A reversed addition of reactants to the methanolic suspension of borate ores leads to an alternate mechanism.  Thus, sulfurdioxide in methanol generates methylborate from borate ores.  Then, ammonia transforms the ester to the methylborate-ammonia adduct which stabilizes in the form of ammoniumpentaborate in the presence of adequate amounts of water and heat.
