Abstract: Abstract:   The invention relates to an apparatus and method for assessing the air tightness of a structure, such as a building, for the purpose of estimating the need to add caulking, weatherstripping or the like to the building to minimize energy loss.  The equipment includes an adjust-able frame and a panel which may conveniently fit into a doorway or window frame of the building and seal the same against air leakage except for an air pathway passing through the panel.  The pathway has a fan or the like for causing air to flow through the pathway, preferably from the inside to the outside to create a partial vacuum inside the building.  Pressure sensors are provided to measure the partial vacuum and the air pressure inside the air pathway.  From these measurements and a knowledge of the total internal volume of the building structure, the air leakage rate of the structure can be determined and expressed, for example, as a number of total volume changes per hour.  The apparatus is portable and can be used for almost any building without structural modification.

Abstract: ABSTRACT IMPROVEMENTS IN OR RELATING TO CARRY                CIRCUITS       A chain-type ripple-carry generating circuit having a plurality of cascaded stages is provided with a regeneration network in each stage for restoring the logic level of a carry signal propagating through the stage.  In one embodiment of the invention the regeneration network is designed to restore a carry-not bit and comprises an MOS transistor having its conduction channel coupled between the input of the stage and a ground terminal, the gate of the transistor being driven by a two-input NOR gate, one input of the NOR gate being connected to receive a precharge clock signal and the other input being connected to the input of the stage.  When the precharge clock signal is at a logic "0" level and the input of the stage receives a carry-not bit at a logic "0" level, the NOR gate drives the MOS transistor into conduction causing the input of the stage to be pulled to substantially ground potential.
