Inventor: SHICKEL ROBERT J
IPC: B32B5/22
Filed: 1990-03-13
Abstract: ABSTRACT OF THE DISCLOSURE         A laminated insulating material of the type utilizing at least two layers of insulation medium and in-cludes a third layer of closed cell plastic interposed between each insulation layer.  The air space created within the closed cells absorbs otherwise escaping thermal energy thereby reducing the amount of kinetic energy escaping out of the insulated environment.  The third in-sulation layer serves as a secondary barrier to absorb residual thermal energy passing through the plastic layer.       The arrangement of the laminated material increases the efficiency of the insulation as a thermal barrier thereby allowing it to operate more effectively in comparison to other known insulating materials.  An additional facing of one, two or three plies of sheet material may also be fixed to the outer face of the third insulation layer.

Title: Broadband switch using deactivated crosspoints for establishing switching paths
Inventor: COOPERMAN MICHAEL
IPC: H03K17/693
Filed: 1990-05-01
Abstract: BROADBAND SWITCH USING DEACTIVATED CROSSPOINTS        FOR ESTABLISHING SWITCHING PATHS            ABSTRACT     A broadband space switch matrix constructed from a plurality of NAND gates arranged into a set of cascaded stages to form a tree-switch multiplexing configuration.          A plurality of input digital signals are applied to input ports coupled to the NAND gates in the first stage.  A selected one of the input signals emerges as an output signal from an output port coupled to a single NAND gate in the last stage.  Each NAND gate has a select line for receiving control signals.  The switching path for the selected input signal is established by placing the sequence of NAND gates defined by the selected switching path in a state of conduction whereby only the selected input signal propagates through the switch.  This is effected by forcing to a HIGH state the particular NAND gates in each stage whose outputs are coupled to the same NAND gate in the following stage along with the output of the NAND gate in  the current stage which is in the chosen path.  The forced HIGH state is achieved by applying a LOW state signal to the respective select lines of the par-ticular NAND gates.  In an alternate arrangement, the NAND gates in the first stage are replaced by 2:1 pass-tran-sistor-selectors which offer a reduction in the number of transistors.
