Abstract: A yieldable detent unit useful for pump-down well tool train operations that imparts a selected time delay from moment of unit engagement with a stop shoulder in a tubing run until the detent stop action is released, thereby causing a controlled duration fluid pressure increase pulse to be generated in the pump down system.

Abstract: A three-compartment, heated-environment conveyor structure equipped with individual compartment material-lay-down delivery systems, processing a three-layer building panel material product, continuously, by compartment-to-compartment material laydown, as the product buildup is conveyor-advanced through the machine. The apparatus and process is for manufacturing a continuously extruded running length of construction paneling from continuous flow sources of thermoplastic material bits and a mixture thereof with cellulose fiber bits, by successively fusing and pressure rolling even-distribution layers of thermoplastic bits, a mixture of thermoplastic and cellulose fiber bits, and, again, thermoplastic bits, in respective ones of three cascaded oven chambers through which a material carrying conveyor is selectively advanced.

Abstract: A threaded interconnect structure incorporating respective matching internal and external threaded portions of members to be threadedly interconnected, with the thread geometry defining a profile having contiguous straight-thread and tapered-thread sections. Sealing integrity and make-up length and sealing predictability of the threaded interconnection are improved over standard tapered-thread joints. Tapered sections have a taper in excess of standard taper-threaded profiles and comprise comparatively fewer threads, with the sealing action in the tapered section being mechanically aided by the straight-thread sections during make-up of the joint, and thereafter mechanically reinforced by the straight-thread sections. A tool chaser of new and novel design permits cutting straight-tapered profile transitions with maintenance of pitch and thread matching.

Abstract: A combination seat mounting support and armrest for concrete stadium riser installation where backrests cannot be used or are not desired.

Abstract: A shock absorbing interconnect assembly employing a hydraulic cushioning device of relatively short stroke, mounted in a scissors-like system of levers having respective length ratios which effect an amplified stroke as concerns the interconnect assembly. The ends of the hydraulic cushioning device are pivotably mounted to respective ones of a pair of arm members that, themselves, are pivoted about a common pivot axis. Stroke amplification is realized between mounting plates pivotably mounted to respective ones of the arm members at points longitudinally displaced from the common arm pivot axis. Limited motion between relatively movable members permits bonded seals at all otherwise environmentally exposed points.

Abstract: A binary address memory unit which generates, in response to successive command inputs, successive binary output address words which progress directly according to binary count. Each command input provides for generation of time sequenced clock pulses which, in conjunction with an adder circuit, causes a next successive higher output to be generated from an output register and causes binary one to be added to that output as a stored address to be read out upon the time occurrence of a next successive input command.

Abstract: Fresh cut flowers and foliage are preserved by drying with a material composed of ground, harvested crop residues sprayed with oil.

Abstract: Control apparatus for automatically enabling and disabling the thermostatic control of a plurality of building temperature control units. A programmable timer is provided for adapting the control apparatus to a desired building use schedule. A manually operable override switch is also provided to allow for temperature control during unscheduled building occupancies and additional circuitry automatically disables the override switch to prevent the control apparatus from remaining overridden for an extended period of time in the event the override switch is not reset. A temperature limit switch is further provided to return the temperature control units to thermostatic control if the building temperature drifts outside a predetermined range during periods of disablement.

Abstract: An automatic scoring system for the game of bowling utilizing 30 scratch memories arranged in 10 successive groups of three, corresponding to the three possible score additions in each of ten successive bowling frames. Input information in the form of successive ball pin scores is sequenced on a common input line to each of the scratch memories. Thirty logic gating circuits, associated with respective individual scratch memories, and operating in time synchronism with the sequenced input information, determine, from the number of ball scores presented and the values of sequential scores, into which one or ones of the scratch memories successive ball scores are entered as a score addition in that place at that time. The system collates consecutive ball scores into the scratch memories such that summation of entries into from one to three of the three scratch memories for a logically determined complete frame represents the score in that frame.

Abstract: A medical emergency patient treatment unit that contains a variety of emergency treatment medications, supplies and equipment, all grouped in coordinate end use groups color coded to referenced sets of emergency treatment instructions in a medical treatment book mounted thereon. The treatment units are designed to be readily removed and stationed in locations of probable emergency situation occurrence.

Abstract: A control circuit for reading from, and writing into, a random access memory into which successive data entries are stored at addresses in sequential binary order. A scan generator provides a repeated sequence of all sequential binary order addresses to the memory, and the write-enable input of the memory is controlled in synchronism with the memory addressing by continuously comparing the desired addresses of next-date entries with the scan generator addressing output, and enabling the write function of the memory when these addressing signals are the same.

Abstract: A command signal circuit accepting switch input information from a plurality of mechanical switches introducing undesired contact bounce, and providing a single clean output command signal. The circuit accomodates the plurality of input switches with circuit sections in parallel and "OR"ing to the output resolving all switch commands to one signal. Filtering is applied at a logic receiving end of lead lines to take out noise ripple induced with long leads, and the filter output is applied to both a one-shot multivibrator and a delay circuit having outputs "OR"ed together with the one-shot taking out the contact bounce on the leading edge with switch closure and the delay circuit taking care of contact bounce on the trailing portion of the switching action with switch opening.

Abstract: An alignment structure for end to end positioned multichanneled seats and footboards such as may be used for seating stadium stands. Channel shaped inserts positioned in laterally spaced front and rear channels of two end to end seat sections (or footboards) span the joint between the seat sections and extend end wise into each to maintain end to end alignment between the seat sections. Each channel shaped insert is anchored in one or the other of the end to end seat sections and permits expansion and contraction displacement movement between the seat sections.

Abstract: A time space time (TST) switch using two basic modules, a time switching module and a space switching module with individual module elements interconnectable to realize a great range of time division switch sizes and configurations. Control stores and state stores associated with respective switching elements are combined and incorporated into the time switch and space switch modules.

Abstract: A digital data encoding circuit for use in a one-way transmission system utilizes three 8-bit multiplexers to generate and transmit a 64-bit message. Each bit in the message comprises a 4-chip, or time slot, code that includes an embedded clock therein. The encoding circuit repetitively generates the 64-bit coded message but only enables transmission of one message during periodically recurring intervals. In the event a priority message is sensed, the time between the intervals is reduced so that the rate of message transmission is increased.

Abstract: A corona coupling system with a plurality of corona coupling unit blocks, individually snapped on spark plug wires and coil wires, interconnected by wire for corona coupling distribution between the spark plug and coil wires. The blocks are interconnected by two generally parallel, insulated wires clamped in place running through each two-piece block by a stamped conductive metal plate having formed-down corners biting into and through insulation on the block interconnecting wires as plastic top and bottom parts of each block are pressed and sonically welded together. The stamped conductive metal plate is formed with a downward longitudinally extended ridge positioned in the blocks so that the bottom edge rests against and along the insulation of the wire on which each block is mounted.

Abstract: A communications system for transmission of low density digital data from a plurality of transmitters to a common receiver. It is a burst-mode frequency shift keying (FSK) communication system useable with a master antenna television (MATV) system that minimizes mutual interference between outputs of a large number of transmitters individually located with TV sets. The transmitters are combined with converters for transmission of programs through the system to individual TV sets as controlled by the users, and with information such as TV channel in use, room number identification, and specialized information such as completion of maid service, fire, and burglary alarms transmitted back through the system. In one system the transmitters use a carrier frequency of 12MH.sub.z, a frequency at the lower end of the passband of a coax system with FSK modulation at an equivalent switching rate of 20KH.sub.z and modulation index of 5 accepting a RF channel loading of up to 700 simultaneous users.

Abstract: An all saturated switching mode solid state gate device logic element used as an RF amplifier transmitter in a communication system.

Abstract: A selective down-hole tool landing shoulder employing a housing with sliding internal sleeve member positionable between first and second detented positions within the housing. Resilient collet members, depending from the sleeve, carry radially inwardly extending bosses which define a full-bore opening with the sleeve in one position, and which are forced radially inwardly by camming action to define a restrictive bore as the sleeve is positioned to the second position.

Abstract: A down-the-hole well tubing protective fluid system, with an injection valve in fluid communication with a ported nipple above a packer assembly, for introduction of protective fluid to the tubing bore. The system includes a concentric protective fluid flow path, extended for fluid flow to below the injection nose and through the bore of the packer, and packer tail pipe for introduction of protective fluid into the well-producing flow path below the packer, to provide protection for the packer assembly, inside and outside, below the packer seal, the injection nose, and the injection valve tail pipe. When the injection tail pipe nose is installed to extend below the lower end of the packer tail pipe, the turbulence caused by production fluid entering the tail pipe nose carries diluted chemical fluid mix up, and around, the outside of the packer tail pipe.
