Abstract: STACKABLE DOT MATRIX                PRINTING CARTRIDGE                  MODULES     Abstract of the Disclosure A high degree of flexibility and speed in dot matrix printing are achieved by providing printing cartridge modules that are so thin, a number can be stacked together and run simultaneously.  Depending on the array used, several lines can be printed at the same time (Fig. 3), or a single line can be developed from a standard dot matrix character 20 into a fully formed character 26.  In one embodiment (Fig. 5), the print wires 32 are formed into a linear array parallel to the flat side of the cartridge module 28, and the modules are stacked vertically with respect to the print medium (Fig. 2).  This embodiment is preferred for overlay printing 26.  In a second embodiment (Fig. 8), the print wires 38 are formed into a linear array perpendicular to the flat side of the cartridge module 36, and the modules are stacked horizontally with respect to the print medium (Fig. 3).       This embodiment is preferred for multiple line printing, and has the additional advantage of being sufficiently flat to fit within the upper and lower planes of a ribbon cartridge 46.  Both embodiments utilize the M-cell electromagnet actuator (Fig. 4) described in U.S. Patent No. 4,134,691 and No. 4,218,148. While the mounting of the actuators and means for guiding the print wires differs considerably in the two embodiments, in all the cases the individual armature 60 mounting 62,64 and armature-print wire movement are in a single plane, and the ankle 8 between the print-wire axis and the armatures is less than 10°.

Abstract: ABSTRACT     Disclosed is a process for chemically modifying a native protein to produce a biologically active modified enzyme-like protein.  A solid support immobilized inhibitor of a model enzyme is prepared.  A native protein is partially denatured and brought into contact with the support immobilized model enzyme inhibitor.  A cross-linking agent is then added to the protein in the presence of the support immobilized model enzyme inhibitor and the nixture is incubated for a time and temperature sufficient to cross-link the native protein.  The modified enzyme-like protein is removed from the cross-linking agent and the immobilized inhibitor and purified to produce a modified enzyme-like protein having the biological activity characteristics of the model enzymatic protein.  The thusly prepared modified enzyme-like protein exhibits different biological activity than the starting native protein.

Abstract: ABSTRACT      An interactive raster-scanned display device has a microprocessor (1) and random access memory (3) which operate to issue instructions to a  drawing  engine  (7)  to  cause  it  to  load  and  erase  image  pel representation in an image buffer  (9)  in order to control display of images  on,  or  removal  of  images  from  a display  screen  (8)  in  a conventional manner.  A cursor control device  (10)  enables a user to interact by means of a cursor symbol with images on the screen.   In order  to  reduce  the  demands  imposed  on  the  drawing  engine  during transformation of images over the screen, the system is configured so that transformation operations are performed using alternative images substituted  for  the  full  images.   Each  alternative  image  contains considerably less detail to be drawn and erased than the full image it replaces and therefore the operation is more likely to be performed at the rate desired by the user.  Thus; complex graphics images containing many vectors are replaced during transformation by simple skeletal or outline drawings.  If a large size cross-hair cursor is used for easy identification on a screen, then this also is replaced by a small symbol whenever it is moved.  At the end of the transformation operation, the full image and the large cursor are restored on the screen.

The pocket is easily ruptured when the mouth is closed and, when mixing, a volume of liquid may be discharged into the compartment for mixing with a material in the compartment.  During mixing the walls of the pocket abut to serve as a non-return valve in the bag.      Apparatus for making the bags includes web bonding means, feeding means to feed film of waterproof thermoplastics material from rolls to the bonding means, and interrupting means to form the mouth in the pocket.      The apparatus may form bags with open bottoms for insertion of the material for mixing and subsequent closure or sealed, filled bags.

Abstract: POOL CLEANER An improved pool cleaner is provided of the type for submerged random travel generally along the floor and sidewalls of a swimming pool to dislodge and collect debris. The pool cleaner comprises an hydraulically contoured housing consisting of a limited number of shell shaped housing portions designed for rapid assembly about an integrated drive assembly having a water-powered drive train encased within the housing and rotatable wheels outside the housing for supporting and driving the pool cleaner. Water under pressure is supplied through a water supply mast detachably mounted on the housing for flow into a pressure manifold from which individual water flows are coupled through appropriately sized nozzles to drive a water turbine of the drive train and through a plurality of jet pump orifices opening generally upwardly about the inner diameter of an open central suction mast through which debris is drawn upwardly into a collection bag. In addition, water from the pressure manifold may be directed through a rearwardly open thrust jet positioned for improved cleaner stability and a rearwardly open sweep hose jet coupled to a flexible sweep hose. A back up valve assembly is mounted within the housing and includes an hydraulic timer responsive to a small bleed flow from the supply mast to periodically divert the pressurized water inflow to a back up jet oriented to drive the cleaner rearwardly and/or upwardly for a short time interval thereby preventing entrapment of the cleaner in a confined region of the pool such as a corner.

Pump 18 transfers the premix stream 22 through static mixer 24 into a wiped surface reactor 27. The reactor can be a counter rotating twin screw extruder which produces polymer stream 36 without the need of solvent and using residence times much shorter than prior art solution or emulsion processes.          Some unique pressure sensitive adhesive acrylate polymers have been produced. They are believed to have a relatively high degree of branching. The bulk polymerization process permits the manufacture of pressure sensitive adhesive articles by extruding directly from the twin screw extruder onto a substrate.
