Abstract: CONTAINER AND CLOSURE               Abstract Of The Disclosure A lid has an inverted U-shaped peripheral rim, which rim snaps over the upper edge of a container sidewall.  There are three separate sealing zones between the lid and the container. first, the cover portion interior of the snap on rim has a plug fit interference relationship with the interior of the container.          Second, the outer leg of the snap on rim has an interference relationship with an outwardly extending sidewall ridge near the upper edge of the container.  Third, the outer leg of the snap on rim also has an inwardly facing ridge which snaps over the sidewall ridge and has an interference relationship with the outer surface of the container sidewall.  A tear-off strip constitutes the lower portion of the outer leg of the snap on ridge and tears off below the inwardly facing ridge.  The lower edge of this tear off strip abuts against a ledge which extends outward from the container sidewall thereby inhibiting tampering with the strip until initial opening is intended.  A vertical weakening line adjacent a pull tab on the tear-off strip further inhibits tampering with the tear-off strip.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE        A test device, test composition, and method are dis-closed for determining the presence of a component in a sample.  The device comprises a carrier matrix incorporated with a reactant system which produces a detectable response upon contact with the sample component.  After a predeter-mined time interval elapses, the production of the detectable response is terminated by an inhibitor system also incorpora-ted with the matrix.  The test composition comprises the reactant and inhibitor systems. The method of use comprises contacting the test device with a test sample suspected of containing the component, permitting a predetermined time to elapse after contacting, and observing any detectable response produced.

Abstract: ABSTRACT OF THE DISCLOSURE           An internal combustion engine of the reciprocating piston type, which is provided with an exhaust gas re-circulation circuit to suppress the formation of NOx and has two or three spark plugs for each combustion chamber. There is a substantial overlap of the opening periods of exhaust and intake valves, so that a portion of the combustion gas is left unexhausted. The com-bustion chamber has a simple shape such as hemisphere, and the spark gaps of the plural spark plugs are arranged distant from each other in each combustion chamber so as to respectively share approximately equally divided portions of each combustion chamber. The number of the spark plugs is two when the volume of the recirculated exhaust gas, including the un-exhausted combustion gas, is about 50% at the maximum of the volume of air admitted into the combustion chamber but three when the recirculated exhaust gas amounts to about 60% of the air at the maximum.

Abstract: ABSTRACT OF THE DISCLOSURE           A device for separating, scanning and sorting publications bearing the Universal Product Code.  The device comprises a flat bed extending horizontally but in-clined to one side, along which move parallel belts at high speed.  A loading bin or hopper at one end receives magazines stacked in random sequence.  These are separated by means of the synchronized movement of stack lifting bars at the bottom of the bin and movable separating fingers downstream.          The fingers drop on each magazine as it begins to pass beneath them, and the stack lifters are simultaneously raised to lift the remaining magazines off the belts.  The fingers are lifted a short time after the trailing edge of the magazine passes them to ensure a gap between adjacent magazines.  The stack lifters drop as the trailing edge passes the fingers, without a time delay.  Means are also provided for initially stepping back the leading edges of the magazines in a stack, this means comprising a novel forward wall construction for the bin, and flat springs between the stack lifters and the separator fingers.         The separated magazines pass a conventional scanner which, through a computer, controls shift registers corres-ponding in number to the diverter gates.  The diverter gates include fingers which are rockable from a position flush with the bed to a diverting position in which a magazine impelled by the belts will strike the fingers and be diverted laterally.  Concave scoop-like members are mounted adjacent each set of diverter fingers to aid the diverting action.

Abstract: ABSTRACT OF THE DISCLOSURE Type Ib diamond crystal is annealed at an annealing temperature ranging from about 1500°C to about 2200°C under a pressure which prevents significant graphitization of the diamond during the annealing to convert at least about 20% of the total amount of type Ib nitrogen present in the crystal to type Ia nitrogen. Where the diamond crystal is of gem quality the lighter color associated with the type Ia crystal isusually preferred.  The type Ia crystal is also harder and stronger for use as an abrasive.  The crystal norphology is unchanged in the annealing process.  Annealing of synthetic crystal results in novel type Ia crystal forms not found in nature such as the cubo-octahedral form, particularly preferred for use in diamond saw blades.

Abstract: ABSTRACT OF THE DISCLOSURE            Connected to the suction pipe leading to a pump inlet is an air eliminator comprising a valve housing defin-ing a chamber and having a first valve seat through which the suction pipe communicates with the chamber and a second valve seat through which the chamber communicates with at-mosphere, the chamber increasing in cross-sectional area from the first seat toward the second seat.  A ball valve is normally seated on the first seat to prevent air from enter-ing the suction pipe but is displaceable to allow discharge of air under pressure from the suction pipe through the second seat while suspended by the force of the discharging air.  The ball valve has a specific gravity less than the liquid, whereby liquid entering the chamber from the suction pipe floats the ball valve against the second seat to block the discharge of liquid.

Abstract: Abstract of the Disclosure Mechanism is provided whereby a machine for inserting multiple leads of a component into a circuit board may be adapted to first insert a lead-receivable socket into the board and thereafter mount a component in the pre-inserted socket. The mechanism preferably is employed in a machine comprising automatic means for sequencing the components and sockets predeterminedly. When the machine further comprises automatic means for positioning the circuit board to receive the successive components and/or sockets, it is contemplated all components and sockets will first be programmed to be inserted directly into the boards, then preferably after soldering to secure them into board circuitry and remounting of the board in the machine, new programming of the board positioning means will mount the proper component into its pre-inserted and soldered socket.      The novel mechanism is provided, for instance, as an attachment to or auxiliary kit for use in a machine for inserting DIP components and/or sockets. Specifically this attachment comprises a movable stop having two abutment or positioning faces one of which is disposed to engage leading leads of a component and the other of which abuts the leading surface of a socket to be inserted. Mounting of the stop is such that it does not approach the circuit board and hence cannot interfere with it or previously mounted components.
