Abstract: A pivot assembly employs a pivot block to resist lateral forces and facilitate door alignment. The assembly includes a sleeve, pivot pin, pivot block and jamb bracket. The jamb bracket is connected to a corner between a jamb and a floor. The pivot block mounts on to the jamb bracket with anchors that engage serrations in a slot of the jamb bracket, The pivot block includes two halves resiliently connected at one end and separated by a gap, with a conical socket centered along the gap. A pivot pin is threaded into a sleeve mounted to the lower edge of a door to adjust height. A head on the lower end of the pin engages grooves in the pivot block socket. The pivot block halves separate to accommodate the pivot pin, and to cause the pivot block halves to be anchored in the jamb bracket. To properly align the door, the door is lifted to disengage the pivot pin from the pivot block. Vertical height is adjusted by rotating the pivot pin in the sleeve. Horizontal adjustments are made by pinching or squeezing the pivot block halves in order to slide it along the jamb bracket slot.

Title: Atm queuing and scheduling apparatus
Inventor: HAYTER ANDREW TIMOTHY
IPC: H04L12/56
Filed: 1995-09-14
Abstract: The apparatus is used for queuing and scheduling ATM cells across an ATM switch. A sustainable cell rate calendar is connected in series with a peak cell rate calendar and cells are scheduled independently in each. The sustainable cell rate calendar guarantees the maximum ATM cell delay is not exceeded.          The ATM cells are not placed on the peak cell rate calendar unless the peak cell rate threshold might be exceeded. In this case the cell is scheduled on the peak cell rate calendar and it is this that determines when the cell is sent. In this way, it is possible to guarantee absolute minimum and maximum cell rates of a connection.

IPC: H05K1/16
Filed: 1995-10-13
Abstract: Method and apparatus for fabricating fine pitch pattern multilayer printed circuit boards involving laminar stackable board layers providing power distribution, signal distribution and capacitive decoupling.  In one respect, the invention relates to the fabrication of board layers by beginning with a metallic core, patterning the core, selectively enclosing the core in a dielectric, selectively depositing metal to form vias, plugs and signal lines, and forming dendrites with joining metallurgy on the vias and plugs to provide stackable connection from above or below the plane of the board layer.   In another aspect, the invention is directed to the use of a sol-gel process to form a thin high dielectric constant crystalline film onto a metallic sheet followed with a deposition of a metallic layer onto the high dielectric constant film.  The film serves as the dielectric of a capacitor layer which is thereafter in succession patterned, covered by a dielectric, and has selectively deposited a metallic layer for interconnecting the capacitor and forming vias.  The ends of the vias are thereafter subject to dendritic growth and joining  metallurgy  to  provide   stackable   interconnection capability.   A multilayer composite laminar stackable circuit board structure is created using, as appropriate, layers having metallic cores and layers having capacitively configured cores. The multilayer laminar stackable circuit board provides direct vertical connection between surface mounted electronic components and the power, signal and capacitive decoupling layers of the composite board through the dendrites and joining metallurgy of the via and plug formations.

Title: Process and device for purifying chemical substances
Inventor: K NIG AXEL
IPC: B01J2/26
Filed: 1995-04-20
Abstract: Wash columns as used to remove impurities from the residual melt from melt crystallization are of limited efficiency due to the fact that the crystal mass normally fed in contains solids of different sizes, which partially also tend to agglomerate. The purifying action based on the flow around these solid components is therefore limited. The invention proposes to load wash columns with monodisperse particles produced beforehand by means of suitable granulators. The invention also relates to the use of this process and of this device for purifying and preparing chemical substances.

Inventor: BAGGETT WILLIAM CALVIN
IPC: H01R4/24
Filed: 1996-05-07
Abstract: An insulation displacement connecting (IDC) terminal that accepts two insulated wires in a single slot for the making of an electrical connection. The IDC portion of the terminal, which cuts into the insulation of the wire to establish contact, is designed with large flat spring contacts about a centrally located slot, wherein the contacts displace torsionally when normal forces placed on the terminals exceed a fixed load. The torsional displacement is enabled by the inclusion of a widened slot proximate a base portion of the terminal. The widened slot in combination with an angular orientation of the terminal contained within an insulated connector module housing enables the contacts to twist away from one another. This displacement effect allows for larger gauge and more than one conductor to be inserted into the terminal without permanently yielding the beam contacts of the terminal. The widened slot included at the base of the terminal also allows for removal of a first wire without disturbing the connection of a second wire. The terminals are adapted for use with connector modules which house multiple pairs of IDC terminals on both the front and rear sides thereof. The connector modules are insertable into a hinged mounting bracket that is mounted at a telephone switching area to make up a modular connecting block.

IPC: B65G21/20
Filed: 1996-06-25
Abstract: A double backer for curing the web bonding adhesive  and  drying the corrugated paperboard  web utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel.  Supplemental holddown force may be provided by banks of spring fingers supported above and in contact with the holddown strips on a transverse support rod which may be rotated to vary the amount of supplemental holddown force.  Alternately, the holddown strips may comprise continuous cables in which one run of the cables rests upon the moving web to provide the web holddown and a second run includes high friction cable portions which are movable into driving contact with the upper surface of the web to pull it through the heating section, as for initial web thread up.  An embodiment  is also disclosed in which the holddown strips are tied together laterally to form a more stable mat-like holddown system.
