Abstract: ABSTRACT      A mining machine for enlarging a pre-existing bore by out-cutting, said machine comprising a)  a non-rotatable body member b)  a pair of wing-cutters pivotally mounted to said body member, having rotatable cutting portions thereof, c)  conveying means mounted behind said wing cutters in operative association with said body member, for conveying coal or the like cut by said wing-cutters away from the cutting site, d)  means for pivotally moving said wing cutters with respect to said body member from a first position, wherein said wing cutters are generally in line with said body member and said conveying means and no substantial amount of coal or the like is cut thereby, to a second position wherein each said wing cutter extends outwardly with respect to said body member, making an angle with a line between said body member and said conveying means and in which second position a substantial amount of coal or the like is cut thereby, e)  means maintaining said wing cutters in said second position during out-cutting, and f)  means for rotating the rotatable cutting portions of said wing cutters.          The machine has the advantages of less wasted set-up time for mining with a machine of a given size, the mining of larger bores, the capacity to retrieve coal, ore, etc. from bores that have been made previously.  Operators are not required to go into the bores being formed or enlarged which represents an important safety factor.

Abstract: TITLE:      CASETTE FOR USE WITH AN I.V. INFUSION CONTROLLER        INVENTORS:  SCOTT T. GARRETT             LEE K. KULLE WILLIAM L. RUDZENA                         ABSTRACT       A casette employing a stretchable elastomeric membrane used with an intravenous infusion controller to limit the fluid flow to a patient.  The casette includes two sections of rigid plastic fused together with the membrane between them.  The membrane and one section of the plastic form the channel through which the intravenous solution passes.  The other section of plastic limits the expansion of the membrane to a predetermined size in order to provide the casette with a chamber of known volume.  A valving configuration in the inlet and outlet to the chamber controls the fluid flowing through the casette and, thus, to the patient.  Each valve includes a section of the elastomeric membrane in proximity to a configured portion of the piece of plastic forming the channel with the membrane.  To close the valve, the controller extends a shaped elongated member through the other section of plastic to stretch the membrane and force it into contact with the configured plastic.  Alternately opening and closing the inlet and the outlet ports at appropriate time intervals limit the fluid that can pass through the casette.  The plastic forming the chamber with the membrane may also include a groove to allow the passage of fluid through the casette when outside the controller.  Small circular grooves allow for the removal of air bubbles in the chamber when first priming it for use with the intravenous solution.

Abstract: ABSTRACT OF THE DISCLOSURE           Can bodies are held by means, such as a vacuum, magnetic or other means onto rotating, disc-shaped pads which accompany the cans throughout an indexing route.  A can centering guide positions each can on the center of one of the pads to insure eventual alignment with spray guns at two spray stations downstream.  A spinner-drive belt encircles a turret and forms a substantially continuous rotational drive for spinning the can-bearing pads.  When a vacuum means is employed, the vacuum means comprises a vacuum manifold in the rear of the turret and has manifold groove for vacuum communication with the can through the vacuum pad.  As the can-bearing vacuum pads pass along the manifold groove, the cans, being securely centered on the vacuum pads, rotate at the same velocity as the belt-drive vacuum pads.

Abstract: ABSTRACT OF THE DISCLOSURE        A separable slide fastener having a separable assembly comprises a pair of stringer tapes each carrying along one longitudinal edge a row of coupling elements each having a pair of spaced legs and a coupling head extending between the legs.  The separable terminal assembly comprises a separable pin and a retainer pin fixed to the bottom end of the respective tapes and a retainer formed integral  with the retainer pin for receiving the separable pin.  The rows of coupling elements can be interlocked by interengagement of a pair of lateral projections of the opposed coupling head.          The lateral projections of the endmost elements located adjacent to the pins are cut off to permit the endmost coupling elements to freely move away from each other when the slide fastener is closed.  The invention improves the smoothness of movement of the slider towards and away from the separable terminal assembly.  Also, the production costs are reduced due to a simple structure.

Abstract: INTRUSION ALARM SYSTEM ABSTRACT OF THE DISCLOSURE            An intrusion alarm system and method is provided which includes one or more sound pulse transmitters that are triggered upon the opening of an entryway, such as a door or window, to produce a high-intensity sound pulse having a decibel level above a predetermined minimum.  For example, each transmitter may comprise a percussive photoflash unit in combination with a pyrotechnic device which responds to the radiant output of the fired photoflash unit to emit the intense sound pulse.  A centralized detector responds to the sound pulse above a predetermined threshold level to produce an alarm signal.  Preferably, the detector comprises an electroacoustical transducer arrangement which  provides the dual functions of both sound pulse detection and generation of an audible alarm.

Abstract: ABSTRACT This invention relates to a field test unit to determine the presence of cannabis (marijuna, etc.). No such field test units are known in the prior art.  It has been known to be capable of making tests for the presence of cannabis within a laboratory.  The present invention takes the form of a tubular device composed of a pair of members telescopingly interconnected together to form an internal enclosed chamber.  An elongated swab having an absorbent tip is removably located within the internal enclosed chamber.  One of the members of the housing has attached a pair of separate compartments which are interconnected by a frangible seal and further being interconnected to the internal chamber by a frangi-ble seal.  Each of these compartments contain a different substance.  A breaking of the frangible seal between these compartments causes intermixing of these substances. Breaking the frangible seal to the internal chamber subjects the tip of the swab to the intermixed substances. The other member of the housing has attached at its closed end a third compartment which contains a third substance.  This third compartment is separated from the internal enclosed chamber by a frangible seal.  After the tip of the swab has been placed in contact with the drug contact area, and in contact with the first two sub-stances, the tip of the swab is then placed in contact with the third substance after breaking of its adjacent frangible seal.  If the tip of the swab was in contact with cannibus, it would change color.

Abstract: ABSTRACT OF THE DISCLOSURE A "ready" indicator for high-voltage switchgear of a type which contains switches having a normal position (opened or closed) and a switch operator therefor. The switch operator may include a stored-energy device which may be in a charged or an uncharged state, and an automatic control device which, de-pending upon circuit conditions, causes operation of the switch operator to put the switch in a selected position. The "ready" indicator includes appropriate sensors which detect the presence or absence of certain conditions. For example, the sensors may detect the ability ot inability of the automatic control device to effect operation of the switch operator, the position of the switch operator which indicates the position of the switch (opened or closed), charged or uncharged states of the stored-energy device in the switch operator, and whether or not the switch operator is properly coupled to the switch. The sensors provide signals to logic circuitry which produces an indication of whether all of the switches, switch operators, automatic control devices, and the like found in the switchgear are in an appropriate condition.
