Abstract: METHOD FOR FABRICATING MOS          DEVICE WITH SELF-ALIGNED CONTACTS                   Tarsaim Batra ABSTRACT      A method for fabricating an integrated circuit semi-conductor device comprised of an array of MOSFET elements having self-aligned or self-registered connections with conductive interconnect lines.  The method involves the formation on a substrate of a thick oxide insulation layer surrounding active area openings.  A gate electrode within each opening is utilized to provide self-registered source and drain regions.  In two embodiments, the gate is covered on all sides and on its top surface with a protective layer of nitride or thick oxide.  In one of the embodiments, after the formation of the source-drain regions a relatively thin protective layer of etch stopper is applied to the entire chip prior to the application of an upper insulative layer.  When oversized windows are etched in the upper insulative layer, the etch stopper layer prevents etching of the nitride layer, thus preventing shorts or leaks between  conductive  and  active  areas  and providing self-aligned contacts with minimum spacing from adjacent conductive areas.  In another of the embodiments, a thick layer of oxide provides insulation between the gate, source-drain region and conductive lines.   Two other embodiments teach novel methods of forming thick oxide protective layers for the gate sidewalls.  With these methods, additional internal protection over prior art devices is provided in MOS devices with source-drain regions formed either by diffusion or ion implantation.

Abstract: APPARATUS FOR DISSOLVING SOLUBLE COFFEE                  Abstract of the Disclosure Apparatus and method for making large volumes of hot coffee wherein soluble coffee (i.e. freeze-dried or other instant coffee) is mixed with a relatively small stream of cool or cold water and the resulting mixture is sucked into a relatively large stream of hot water by jet action.  The dry soluble coffee in the form of powder, crystals or flakes is metered by an auger from the bottom of a hopper through a discharge nozzle and falls into a mixing bowl wherein the cool or cold water is flowing in the form of a vortex.  The cool or cold water spirals down the side of the bowl in the form of a water curtain which wets and sweeps the interior surface of the mixing chamber thereby preventing buildup of soluble coffee solids thereon and inside the mixing chamber.  The resulting mixture is sucked or drawn by jet action from the bottom of the mixing bowl into a conduit in which a stream of hot water is flowing in sufficient velocity and volume to create suction in a connection between the bottom of the bowl and the hot water conduit.  The suction prevents steam or hot moisture from rising in the mixing bowl and reaching the dry instant coffee in the hopper or discharge nozzle.  An easily detachable and replaceable nozzle cap for the projecting end of the auger facilitates quick and easy access to the auger and discharge nozzle, not only for periodic routine cleaning when the apparatus is empty but also when the apparatus has sat idle for several days in a humid atmosphere with soluble coffee solids in the hopper and discharge nozzle.

Abstract: RING TRIP DETECTION SYSTEM                         ABSTRACT          Ring trip is detected when a telephone set which is being rung goes off-hook, through the use of a comparator in which the ringing signal superimposed on battery feed voltage is compared with a fixed reference voltage closer to ground than the battery feed voltage. Inasmuch as the duty cycle of the ringing signal with respect to the reference voltage is less than or equal to 50% under pre-trip (on-hook) conditions and will increase under trip (off-hook) conditions, the compar-ator output is a square wave form of corresponding duty cycle.  An up-down counter is caused to count up when the comparator output wave form is of one level and down when the comparator output wave form is of another level during each cycle of the ringing signal.  The counter counts up during the portion of the comparator wave form which determines the duty cycle and down during the rest of the period of the cycle.  Underflow and lack of underflow states of the counter respectively indicate nonring trip and ring trip conditions.  Logic responsive to these conditions causes deactuation of a ringing relay to enable disconnection of the ringing signal from the ring lead going from the line circuit to the tele-phone set.  The line circuit has a calling bridge which provides an output which is used to prevent the ringing relay from reoperating unless the telephone set remains on-hook after ring trip detection

Abstract: ABSTRACT          A process and composition for applying and bonding an amine curable polymer or prepolymer at ambient temperatures to the surface of a cured elastomer substrate.  The elastomer article or sub-strate is treated with an organic oxidant such as an N-halohydantoin, N-haloamide, or an N-haloimide, for example, the various isomers of mono-, di-, and tri-chloroisocyanuric acid.  A polyisocyanate is applied thereto.  A composition of the amine curable polymer or prepolymer is prepared with an amine curing agent. To the curing agent and curable polymer or prepolymer composition is added a polar solvent which is mixed with the resulting blend or mixture and added to the treated elastomer surface; said polymer or prepolymer cures at ambient temperature and becomes bonded to said elastomer.  The application is relatively easy, since the entire mixture is a liquid and can be applied in situ.  The invention is particularly suitable for repairing various damaged elastomer articles such as tires (especially off-the-road), conveyor belts, hoses, preparation of caulking or sealing compounds, and especially in bonding tire lugs or tire treads to a tire carcass.

Abstract: STACKING APPARATUS FOR FLEXIBLE, GENERALLY PLANAR FOOD PRODUCTS                          ABSTRACT           An apparatus for counting and stacking food products such as tortillas.  The tortillas are initially placed on an entry chute containing a large number of air outlets for creating a cushion of air to allow the tortilla to slide down the entry chute onto a incline conveyor belt.  The conveyor belt is of an open mesh design and it is supported on a belt support having a large number of air inlets which create a vacuum that maintains the tortilla in contact with the belt.  The tortillas are carried by the belt down one end of the belt support and along the underside of the belt support with contact between the tortilla and belt being maintained by vacuum creating air inlets formed in the belt support.  The air inlets terminate at a location on the underside of the belt support thereby allowing the tortillas to drop from the conveyor belt.  The tortillas drop onto a stationary rack formed by rods which are interleaved with conveyor belts moving together as a unit.  The conveyor belts are normally positioned beneath the upper surface of the rack.  However, when a predetermined number of tortillas have been stacked, the belt is lifted thereby carrying the tortillas from the rack.  The mechanism for lifting the belts is actuated by a counter which counts a predetermined number of tortillas passing past a counting station and delays actuating the belt lifting mechanism until the final tortilla has dropped onto the rack.  The belts discharging the stacks of tortillas move in the direction opposite the direction that the tortillas are delivered to the rack in order to minimize the time required to remove the tortillas from the rack before an additional tortilla may be placed thereon.

Abstract: Abstract A device for monitoring the fatigue life of a structural member is comprised of at least one and preferably a plurality of substantially flat, elongated coupons which are fabricated of the same material as that of the member being monitored.  The coupons are secured in parallel to the member so that they all experience the same strain history as the member.  Each of the coupons includes a different stress concentrating notch pattern so that the application of the same strain to all of the coupons results in the development of different stress concentrations within the coupons.  The development of different stress concentrations within the coupons causes each coupon to have a different fatigue life, the fatigue life of each coupon being a predetermined percentage of the fatigue life of the structural member being monitored.

Abstract: DEVICE AND METHOD FOR COLLECTING A DESIRED WEIGHT AMOUNT OF A MATERIAL     ABSTRACT A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected.  The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period.  In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system.  A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period.  The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.
