Abstract: ABSTRACT OF THE DISCLOSURE An enzymatic determination of one of the co-enzymes adenosine triphophate (ATP) or flavin mono-nucleotide (FMN) based on the use of an flavine adenine dinucleotide (FAD) synthetase-active system in conjunction with the other coenzyme to generate FAD. The generated FAD can then be measured to determine the ATP or FMN concentration in the sample. Preferably, the generated FAD is measured by com-bination with a corresponding apoenzyme, preferably apo(glucose oxidase), and measuring the activity of the enzyme produced. The resultant active enzyme is preferably measured in a manner which results in a colorimetric response. The present invention provides an ATP or FMN assay which combines the sensitivity of bioluminescent assays with the convenience of a colorimetrically detectable response.

Abstract: A B S T R A C T     A seedling  tray  has  intercalating  seedling  cavities extending oppositely from mouth openings in top and bottom faces of the tray to bottom regions near to the said faces,  thereby rendering the tray reversible.   Each seedling cavity converges from its mouth opening to its bottom region which as a bottom opening.  In use, the seedling tray has a plurality of upwardly open seedling cavities filled with a suitable growing medium such as  soil or mulch.   Seeds are planted in such medium in each upwardly open  cavity.   Inverted  seedling  cavities  act  as  air ventilation  passages  extending  upwardly  and  are  interspersed between  the  planted seedling  cavities.   The  air  ventilation passages intercalate with and are spaced uniformly between the planted seedling cavities.   When the seeds have germinated and developed into seedlings,  the seedlings may be transplanted as desired.

Abstract: ORBITAL-ACTION RECIPROCATING POWER SAW                 ABSTRACT OF THE DISCLOSURE    An orbital-action reciprocating power saw includes a motor-driven transmission that causes a saw blade carrier to reciprocate along an axis of reciprocation and move in a direction transverse to the axis of recip-rocation to provide an aggressive cutting action.  The transmission includes a rotary-to-reciprocation drive mechanism defined by a rotatably driven gear having an eccentrically mounted pin that engages a slotted yoke connected to the saw blade carrier.  The saw blade carrier is mounted in a 'floating' bearing that accom-modates both reciprocation and movement in a direction transverse to the reciprocation axis.  A rocker arm is pivotally mounted intermediate its ends with one end engaging the floating bearing mount and the other end engageable with an axial-face cam portion of the rotat-ably driven gear.  The rocker arm is effective to move the saw blade carrier in a direction transverse to the axis of reciprocation to provide the desired orbital action.

Abstract: Title:  Down Hole Pump Having a Gas Release Valve Abstract of the Disclosure A downhole pump having a gas release valve which valve can be easily applied to the fixed barrel of a conventional downhole traveling plunger pump by merely lengthen-ing such barrel.  A trip on the pull rod attached to the plunger lifts off a valve element of the barrel valve seat to release any gas or foamy oil otherwise trapped between the lower standing valve and the traveling valve of the plunger.  Such release takes place on each stroke of the pump.  The invention is useful for obtaining oil under subterranean formation conditions that do not normally permit such recovery efficiently due to gas locks and can be either provided in a downhole pump or added to a conventional traveling plunger preexisting pump.

Abstract: "CABLE TRAP"            ABSTRACT OF THE DISCLOSURE            A hairpin spring type trap includes a pair of arms normally urged apart by the spring situated at the inner ends thereof.  A cable loop is secured by one end to the distal end of one arm and passes through a guide loop in the distal end of the other arm and is secured to a bracket or clip slidable along the arm through which said loop passes.   This bracket is frictionally adjust-able along the length of the arm when the trap is in the set position.  A trigger is pivoted on the other arm and a setting plate extends  from the one arm towards the other arm.   This plate is provided with opposed jaws on the  distal  end  thereof.   When  set,  the bale of  the trigger engages one jaw and the lower arm engages  the other jaw with the spring pressure retaining the trap in the set position.   Pivotal movement of the trigger in either direction release the trap.   If the trigger is swung upwardly against the one arm, the trap is held in a safety position.  A retainer may be secured to a support-ing surface such as a tree or a deadfall and the coil spring engages over a hub on the retainer when the trap is set thus supporting the trap substantially horizontal-ly.  When  sprung  or  released,  the  trap  automatically disengages from the retainer and hence the tree or dead-fall and is held to the retainer by means of an anchor wire or cable.  When sprung, the bracket, together with the trigger move along the lower arm as the arms diverge thus allowing the cable loop to shorten around the animal thus trapping same within the cable loop and against the lower arm.

The preferred embodiment exemplifying the invention is a five gear assembly of  two input gears and three output gears selectively connectable for two wheel or  four wheel high speed operation, or four wheel low speed operation beside a neutral mode.  The rear output shaft is aligned in a straight line with the  rear  drive  shaft  extending  downwardly  toward  the  rear  wheel differential while the  front  output  shaft  extends  downwardly  in  the opposite  direction  to  the  front  drive  shaft  toward  the  front  wheel differential.

Abstract: PHN 11.547                16                 22.1.1986 ABSTRACT: Power-supply circuit.              For charging a battery (6) from different input voltages use is made of a flyback converter in which during the forward interval a linearily increasing current flows through a transformer primary winding (n1), which current is turned off by a first switch (S1) at a value which is dictated by switching means (3). During the flyback interval the energy stored in the transformer (Tr) is then supplied to the battery in the form of a charging current via the secondary winding (n2) and a diode (D1). The voltage pulses appearing across the secondary winding (n2) during the forward intervals are applied to an integrator (11) via a third switch (S3), which integrator integrates these voltage pulses. If the output voltage of this integrator (11) exceeds a first threshold value a threshold circuit (12) is activated and turns on a second switch (S2) to disable the flyback converter. If sub-sequently the output voltage of the integrator (11) decreases below a second threshold value, the second switch (S2) is turned off again by the threshold circuit (12), so that the flyback converter can be restarted. In this way the average value of the voltage across the secondary winding during the forward intervals is maintained substantially constant. Thus, the flyback converter constitutes a constant-power source, the power supplied to the battery (6) being constant and independent of the input voltage.            Figure 1.
