Abstract: ABSTRACT OF THE DISCLOSURE      A printing apparatus is disclosed which is capable of printing indicia, such as letters, on articles where the rela-tive positioning of the letters as individually printed is presented in a desired format.  The apparatus is adapted to determine the relative positioning between a letter printed and the next particular letter to be printed and thereby adjusts the relative position of the article to printing device to print the next letter in the proper location to give the desired relative spacing.  Thus, the system printing is dependent upon letter spacing established by a predetermined scheme for spacing between particular letters.  Such apparatus may be adapted for the automated hot stamping of letters into articles.

Abstract: THERAPEUTIC DEVICE     ABSTRACT OF THE DISCLOSURE            A tubular inflated bag is progressively rolled onto a limb thereby applying continuous pressure to the limb.  The bag is initially located about a tubular support and the limb to be treated is located axially parallel  with respect to the support.  An outer sleeve surrounds the tubular bag and is progressively moved toward the limb.  As the sleeve moves toward the arm, the progress of the sleeve causes the bag to roll onto the limb progressively applying pressure to the limb.  The progress of the sleeve is twice as fast as the progress of the bag.  Therefore, the sleeve may be telescoping or collapsible so that the sleeve does not unnecessarily limit the movement of the bag.

Abstract: ABSTRACT OF THE DISCLOSURE   A continuously operating board press in which board material to be pressed is guided between two continuously circulating endless belts in such a way that at least the upper press belt runs through a pressure chamber, whereby a pressure arrangement exerts a pressure loading on the belt and the board material. Walls that laterally define the pressure chamber are elastic and on lower edges of the walls a weight plate is fastened. The weight plate is flexible at least in a longtiudinal direction of the press. The plate, because of its intrinsic weight, is constantly applied to the upper press belt. The weight plate is provided with one or more conduits for enabling an admission of a pressure medium into a gap between the weight plate and the press belt. The gap is closed off by means of at least longitudinal seals.

The video monitor module includes a CRT display, a serial I/O interface and a processor that processes characters received through the serial I/O interface for display on the CRT screen whether or not the application module is connected.          The processor in the video monitor module detects the con-nection of the application module, and then selects its instructions from a memory in the application module first, to prompt the selection of a mode of operation for the ter-minal, and second, to execute the selected mode of operation.          The application module uses a plurality of keyboard overlays, each corresponding to a respective mode of operation.  In a specific embodiment two of the modes of operation are pro-gramming applications related to programmable controllers.

Abstract: Nelson Case 3488 FASTENER HAVING A SEALING CHIP SKIRT            Abstract of the Disclosure There is disclosed a threaded fastener having a seal means carried by the head thereof which is structured to assure the establishment of a complete and effective seal between the fastener and the work piece surface into which it is driven. The screw or fastener includes a head portion having a clamping under surface and a top surface contoured for interlocking engagement with a driver.  A shank portion extends from the clamping surface and has a transverse dimension smaller than the head portion and a thread.  A seal means or moisture im-pervious cover overlies the head portion and extends axially from the clamping surface for sealing the connection between the fastener and a work piece surface into which the fastener is driven.  The axial extension of the impervious cover forms a flange which is inwardly deformable upon contacting the work piece surface for deflecting work piece fragments which may be produced as the fastener is driven into the work piece away from the seal between the flange and the work piece surface to preclude the fragments from interfering with the seal. The flange and the clamping surface further define a cavity for receiving the work. piece fragments as the flange is deformed for confining the fragments away from the sealed connection and for preventing the free displacement of the fragments.

Abstract: ABSTRACT OF THE DISCLOSURE    The system displays an appropriate two digit fault code if a predetermined push button on the operator keyboard is pressed while a status code is displayed.          When the push button is released, the display returns to the status code.  The fault codes identify sources of malfunctions rather than status code remedies for efficient fault diagnosis and correction.  In a preferred embodiment, there are approximately ninety fault codes available for display covering recirculating document, machine processor, finisher and special occurrence faults.  The capturing of the fault is independent of any clearance.  Thus, even after the machine has been restored to a Ready status or cleared of status codes, the most recent first or highest priority fault is displayable.

Abstract: "SCRUBBER AND METHOD UTILIZING WETTED SLOTTED    SCREENS FOR REMOVING FLYASH FROM FLUE GAS"                              ABSTRACT    Improved scrubber and method for removing particulate matter from hot flue gases, particularly flyash in a sludge incinerator, utilizes a plurality of cylindrical slotted wire screen canisters which are prefer-ably mounted vertically in apertures in a plate in a chamber in which the hot gas moves vertically.  The bottoms of the canisters may be closed so that the vertically moving gases will change direction at least twice as they move sideways through the screen slots and then vertically again in-side the screens, or alternatively, the bottoms can be screens also with a baffle plate positioned under them to cause a change of direction of the gases.  A spray nozzle in each canister keeps the spaced wires forming the sides and the slots wet so that a majority of the flyash will be cap-tured and washed down the sides of the canisters while additional particles will be captured by the water wash spray inside the canisters.  The system is very efficient in particulate collection, uses relatively little water has a very small pressure drop and is quite inexpensive to build since the scrubbing tower can be of a minimal height.  The system can also be retro-fitted to existing scrubbers to improve their performance and lower their operating costs.

Abstract: ABSTRACT      A modified Phillips*-type (cross slotted) cruciform recess in a screw or the like, which provides a cling fit with a driver by causing deflection of the flutes of the driver against the walls of the slot in the recess, comprises a central socket portion and generally radially extending slots adapted to receive the flutes of a suitable driving tool.  Each slot is defined in part by a bottom surface of substantially uniform width which slopes radially inwardly and downwardly along the axis of the screw.  The bottom surface joins two opposing surfaces which form the walls of the slot.  The pairs of opposite slots in the cruciform pattern are not summetrically located relative to a plane including the longitudinal axis of the screw, but are offset laterally in opposite directions with respect to such a plane.  On insertion of a standard driver into the recess, the flutes of the driver are caused to flex into frictional engagement with the walls of the slots, thereby achieving the desired cling fit.     *trade mark

Abstract: ABSTRACT This invention relates to a hinge fitting for a foldable ladder. Fittings presently known in the art have several disadvantages for which this invention seeks to provide a solution.  Some of the problems are the high costs of production, the canting of the locking nuts, the premature wear and failure of the locking device because of the plastic pins employed, and the undepen-dable performance when foreign substances inadvertently penetrate the mechanism. The present invention is of simple, inexpensive construction, and can be manufactured completely of metal, - thus remaining practically free of wear. Not only is the new device unaffected by externally applied foreign substances, but also the locking mechanism remains securely in place even when external force is applied.
