Abstract: ABSTRACT OF THE DISCLOSURE         The dart board game includes a dart, a target board having a target face, and cooperating elements for retaining, on the target face, a removably mounted marker on the dart.  Such cooperating elements can consist of cooperating "Velcro" strip material.  The dart includes a resilient and flexible portion at which the dart body is removably engaged with the marker, so that upon impact of the dart against the target board, the resilient portion of the dart flexes to allow the "Velcro" strip to engage without disengagement due to bouncing.  This flexing motion com-presses the resilient portion, which, as it expands, propels the dart body away from the target board to disengage the dart from the marker.  In playing one embodiment of the game, in order for the "score" of a marker to count, the player throwing the dart must catch the rebounding dart body after an impact on the target board.

Abstract: METHOD FOR HERMETICALLY SEALING   AN ELECTRONIC CIRCUIT PACKAGE  ABSTRACT OF THE DISCLOSURE      A hermetically sealed electronic circuit package is formed by placing a preformed, uncured sealant between a circuitized ceramic substrate and a ceramic cover.  The resultant assembly is placed in an evacuated oven which is preheated to a temperature at least as great as the curing temperature of the sealant.  Before the sealant reaches its melting temperature, the oven is backfilled with nitrogen and stabilized at atmospheric pressure.  The assembly is maintained in the heated environment for a suf-ficient period of time to substantially cure the sealant.          The resulting assembly may be opened to affect any repairs that may become necessary and then reassembled.

Abstract: INERTIA SEAT BACK LOCK            Abstract of the Disclosure An inertia seat back lock includes a frame secured to the seat cushion member and having side walls pivotally supporting the shaft portion of a reel. A coil spring secured to the shaft portion and an abutment of one side wall biases the reel in a winding direction.  A strap secured to the reel and to the pivoted seat back member normally permits free pivoting movement of the back member relative to the cushion member as the reel unwinds and winds.  An inertia responsive member pivoted to the frame includes a pawl portion traversing toothed end plates of the reel and a pair of extensions overlying the shaft portion and located between the end plates and the frame side walls.  The center of gravity of the inertia member normally locates the pawl portion out of the path of the end plates.  When a predetermined deceleration level is exceeded, the inertia member pivots relative to the frame and the pawl portion engages one tooth of each of the end plates to block forward tilting movement of the back member relative to the cushion member.  The flexible strap takes up a portion of the shock loads.  The spring is initially preloaded and hooked to the reel.  When the reel is assembled to the frame and the strap is initially unwound, the outer end of the spring is transferred to the abutment of the frame side wall.

Title: Method and apparatus for detecting a preamble in a bi-phase data recovery system

Abstract: Title of the Invention METHOD AND APPARATUS FOR DETECTING A PREAMBLE IN A BI-PHASE DATA RECOVERY SYSTEM            Abstract of the Disclosure In order to detect the eminent reception of a valid bit serial message, a preamble constituting a string of pre-determined number of clock pulses only is employed.  Prior to detection of the preamble, each clock and data pulse from the raw data stream is applied to the increment input of a reset-table counter.  Each clock pulse is also used to trigger a monostable multivibrator which issues a pulse approximating 3/4 of a cell period.  This pulse is ANDed with the next sub-sequent data period, and if a data "1" bit is detected, the satisfied condition is used to reset the counter.  Thus, the counter can only reach a terminal count if a valid preamble is received.  When the counter attains its terminal count, a latch flip-flop is set and a resultant "separation enable" signal issues to activate straightforward logic for separating the in-coming clock and data pulses.  Setting the latch also disables the preamble detection logic until an "end of data field" code is sensed whereupon the counter and latch are both reset to resume observation of the raw data stream for a preamble.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to FRP members, the apparatus and process for making same.  The FRP members are reinforced with helical strands of reinforcing material dis-posed in expanded helices of opposite hand, the helices of each hand being contained in discrete layers.  The lead angle of each helix may be constant or varied along the length of the member independently of whether the member is cylindrical or tapered in order to provide the desired structural character-istics.  The process comprises impregnating the reinforcing strands with resin and wrapping those strands onto a mandrel by apparatus in which relative rotational as well as relative translatory movement between the mandrel and a winding head may be effected to wrap the strands onto the mandrel.  At least one relative movement may be selectively varied to effect the desired lead angle to the helically disposed reinforcing strands along the length of the mandrel.

Abstract: ABSTRACT OF THE DISCLOSURE        A dispensing type container closure having a lid pivotally mounted on the closure so as to be capable of being moved between a closed position in which the lid closes off an opening through the top of the container and an open position in which this opening is uncovered can be made child resistant in character by including a recess in the top of the closure into which the lid is adapted to fit so that in the closed position the lid cannot be manually engaged to be rotated from the closed position.  A fulcrum is provided within the recess and the lid is  made so that when the lid is in the closed position pressure can be applied to the lid in order to pivot or  move a portion of the lid remote from where the lid is hinged on the closure to a sufficient extent so that this portion of the lid can be manually engaged and moved from the closed position.  Preferably a toggle stru-ture is employed to connect the lid and the closure so as to hold the lid either the closed or the open position. A part of this toggle structure is employed to increase the flexibility of the lid so as to facilitate pressure being applied to move the lid from the closed position.

Abstract: METHOD OF MAKING FOAMED THERMOPLASTIC MATERIALS            Abstract of the Disclosure Foamed thermoplastic materials such as coatings, adhesives and structural bodies are made by a method which offers significant advantages and economies.  The method in-volves the steps of stabilizing a dispersion of gas in a molten thermoplastic material by adding a surfactant to the molten material in a sufficient stabilizing amount and subsequently pressurizing the stabilized dispersion to form a hot solution.          Thereafter, the hot solution is dispensed under lower pressure whereby the gas is released from solution to form a foamed material.  The method is especially advantageous in making hot melt thermoplastic adhesives which are very useful in bonding substrates with efficiency and superior bond strengths.  Con-tinuous and reliable foaming operations are achieved with a uniform quality and output of foamed materials.  Thermoplastic materials are also capable of being foamed with relatively simple mechanical apparatus and under conditions which provide considerable savings of energy.  The number of thermoplastic materials which can be foamed employing the present technique in a controlled manner is unlimited.  The method of stabili-zation is conducted at low or ambient pressures and resulting stabilized hot thermoplastic-gas dispersions may then be pumped with pressurization and dispensed with immediate foaming.
