Abstract: ABSTRACT         A common problem in the art of connecting two electrical components is the providing of a convenient and effective zero insertion force coupling therebetween especially where a plurality of parallel conductors along one component are to be connected with a corresponding plurality along the other.  The present apparatus and method address this problem by providing a split tube edge along one of the two electrical components, the split tube including a memory shape material therein.  When the split tube is opened, the second electrical component is inserted therein whereupon the split tube can be closed. Conductors along the split tube make contact with corre-sponding conductors along the second component when the tube is closed.  The memory shape material in the split tube acts to either open the split tube or close the split tube when the material reaches a characteristic transition temperature.

Abstract: METHOD AND APPARATUS FOR INFLATING BALLOONS AND FOR DEPLOYING A LOAD SUSPENDED THEREFROM     ABSTRACT OF THE DISCLOSURE        This invention relates to a combination balloon-inflation and load-lowering device connectable to a pressurized source of a lighter-than-air gas such as helium and which comprises an inverted cup-shaped member closed at its upper end and open at its lower end containing one or more side-opening ports operative when covered by the neck of a balloon to cooperate therewith and form a one-way valve effective to automatically close and trap the lifting gas inside the balloon once the latter is inflated and the inflation pressure released.  The combination device carries spaced-parallel disk-supporting arms hanging therebeneath that journal the shaft mounting a notched disk that forms a part of a load-letdown device detachably connectable for rotation therebetween.  The load-letdown device is automatically operative with a load suspended therebeneath to slowly lower the latter to the end of a tether.  The invention further comprises the method of deploying a load suspended beneath a balloon which includes the steps of inserting an inverted generally cup-shaped inflation device with a side-opening port and a pair of disk-supporting arms therebeneath into the neck of a balloon and fastening same therein, inflating the balloon through the open end of said cup-shaped device by applying sufficient inflation pressure thereto to expand the neck of the balloon and uncover the port, removing the pressure from the balloon allowing the expanded neck thereof to collapse against said port and seal the pressurizing gas therein, attatching the ends of a shaft mounting a notched disk for rotation about a substantially horizontal axis between said arms, attaching one end of a load-supporting tether to the shaft wrapping the tether clockwise one or more turns around the shaft on one side of the disk, then passing the tether through the notch and taking one or more turns anti-clockwise around the shaft on the opposite side of the disk, and alternately repeating the aforementioned sequence until the free end of the tether terminates adjacent the disk, and attaching n load to the free end of the tether such that upon release of the load to fall freely it will pull upon the tether and cause the disk to flip-flop back and forth to slowly unwind off the shaft and lower the load.

Abstract: ABSTRACT     A children's expandable, accordian-type gate is disclosed which includes safety features for closing off the open,  upper V-shaped openings of the latticework of the gate, which latticework is comprised of a first series of slats parallel to each, and a second series of slats parallel to each other but  angularly  oriented differently from the first series.  The upper V-shaped openings are closed off by upper extensions of the slats forming the boundaries of  the V-shaped openings,  which extensions project above the two, mutually-pivoted upper slat-ends from two adjacent V-shaped openings.  The lower portions of the latticework of the gate may be positioned an approximate constant elevation above the floor or support above which it extends by the provision of sliding mounting brackets for the upper portions of the latticework which allow sliding movement thereof relative to the end posts, while the lower portions of the latticework are provided only with a pivot attachment that prevents such sliding movement relative to the end posts.  Further, there may be provided a central leg brace or support for shoring up the center portions of the latticework, especially when extra-long gates are employed.          Such leg brace has a first upper end pivotally connected  to the upper vertex of a lower diamond-shaped opening of the latticework, and has a lower end that is slidingly connected to the lower vertex of the same diamond-shaped opening by the pivot pin that pivotally connects the slat-ends forming the lower vertex of the diamond-shaped opening.   mls/LCM

Abstract: ABSTRACT OF THE DISCLOSURE A system of modular precast encasement sections is pro-vided  to  protect  the  outside  drop  of a manhole structure  from damage due to weak ground support and to prevent leakage from said outside drop.  Said precast encasement sections are stacked on top of  a drop  manhole  base  and  on  top  of  each other to a height sufficient  to  surround  and  support  the  outside  drop  tube.  The stack  of  encasement  sections  is  then capped off  with a  solid collar which has a circular opening of a diameter sufficient to receive  the  outside  drop tube.  This circular opening widens to form a shoulder which is adapted to receive and support thereon the lower most opening of a T-coupler for joining a supply line to the drop tube. The precast encasement sections, the solid collar, and the face of the manhole base which is to receive the stack of encasement sections are each provided with grooves on their upper faces and the solid collar and encasement sections are provided with coaligned projections along their lower faces. These grooves and projections serve to automatically align the sections with the manhole base, with the solid collar and with each other when the sections are assembled on site.

Abstract: ABSTRACT      A transportable bus control architecture for single-chip microprocessors is disclosed.  The bus control architecture consists of an interface control unit that is logically independent of the associated co-resident, common clock-driven micro-processing unit.  This independence allows the interface control unit logic to be used with a variety of microprocessing units.  Further, the interface control unit presents an external appearance that is compatible with the peripheral devices of a specific microprocessor referred to as the "compatible microprocessor", thereby making available to an associated co-resident micro-processing unit the support devices of the compatible microprocessor.  The interface control unit can also access other external devices not related and transparent to the devices of the compatible microprocessor.  The interface control unit is logically divided into an execution section and a control section.  The execution section is controlled by the control section and comprises various registers, latches, multiplexers, logic, and data and address paths that provide communication between the co-resident microprocessing unit and off-chip devices.  The control section of the interface control unit executes commands from the co-resident micro-processing unit and also performs bus arbitration, interrupt, and external reset functions.  Bus cycles are of two types: memory- access or service, depending on the command from the co-resident microprocessing unit.  Service cycles perform the interrupt acknowledge functions and other sense and control functions requested by the co-resident microprocessing unit.  These sense and control functions have the special feature of being pin-programmable and pin-readable by the microprocessing unit.  All action initiated by commands from the microprocessing unit elicits a comprehensive status response from the interface control unit.
