Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure is directed to improvements in flying cutters, particularly shears for severing light gage sheet or strip metal.  Conventional flying shear mechanisms include a severing mechanism which is accelerated up to the speed of a moving strip or sheet material and then operated to sever the strip while moving synchronously therewith.  The cutter mechanism is then returned to its starting position in readiness for a further operation.  The present invention is directed to a form of conveyor support, which is arranged to automatically extend or contract is accordance with movements of the shear, so that the sheet or strip material remains effectively continuously supported on both sides of the shear.          The conveyor support system of the invention includes driven conveyor elements, which are guided in part by the moving shear carriage, such that the relationship of the conveyor support to the shear carriage remains constant while the shear carriage is in motion along with the travelling sheet or strip material.

Abstract: APPARATUS AND METHOD FOR LOADING  BLOCK-LIKE ARTICLES INTO A RECEPTACLE     Abstract of the Disclosure The invention relates  to an apparatus and method for loading heavy, block-like articles such as  blocks of cheese weighing 40 pounds or more into flexible receptacles such as thermoplastic bags.  The apparatus comprises a reciprocally movable loading carriage and means for bringing an article to the carriage and positioning the article thereon.    After the article is positioned on the carriage the carriage moves forward towards a wicketed or taped bag whose mouth is held open by a stream of air.   Spreader means are provided on  the movable carriage to stretch the bag mouth sufficiently wide so that a block of cheese may be inserted deep into the bag without contacting the mouth of the bag thereby preventing the deposit of grease from the cheese around the bag mouth which would interfere with a heat seal  closure of the bag.    Pusher means on the carriage push the article  through the spreaders into the bag and the force of the article striking the bottom of the bag will sever it from the tape or wicket holding means and deliver the filled bag to a conveyor where it travels to a vacuumizing and heat sealing station.

Abstract: SELECTIVE THRESHOLD IGNITION CIRCUIT            ABSTRACT         A selective threshold ignition circuit adaptable for use in an electronic ignition system for an engine is disclosed.  A magnetic pick-up produces an AC signal about a DC reference level which has a frequency related to the rotational movement produced by the engine.  A circuit receives this AC signal and produces a corresponding spark timing signal by comparing the AC signal with a DC threshold level.  A selector circuit chooses a first DC threshold level for the comparing circuit which is effectively equal to the DC reference level during the period of engine start up.  The selector circuit chooses a second DC threshold level which is different from the DC reference level when the engine is running and before the engine has been started.   By providing a threshold level equal to the DC reference level during the engine start up mode of operation, an accurate ignition timing signal is produced during this critical period. By providing a different threshold level during the other modes of engine operation, increased noise immunity is obtained during these other modes of operation which results in lessening the chance of noise transients causing a timing pulse which may result in an unwanted ignition spark.

Abstract: Abstract of the Disclosure Pivotally mounted blades within slots of a hous-ing for an arrowhead are retracted for minimum outward extension during flight but expanded and retained in outwardly extended position upon impact with a target.          The blades are retained in the retracted position by frictional engagement with the slots or by frangible or resilient members.  The slot mounting of the blades permits forward pivoting relative to the arrow shaft to facilitate withdrawal from the target.  The amount of outward exten-sion of the blades upon impact is determined by a rear-wardly positioned shoulder.  This shoulder can be the rearward portion of the blade mounting slot or can take the form of a sleeve at the rear of the blade slots.  The sleeve can further have shoulders of differing depths to allow preselection of the angle of outward extension of the blade upon impact via movement between the sleeve and the blade mounting body or housing.  Minimal size with maximum blade mounting strength can be obtained by orienting the blade mounting slots within the body in an offset rela-tion to the central axis thereof.  The blades are retain-ed by transverse set screws, retaining pins or the like for easy attachment or removal.  By arranging the blade mounting body for telescopic movement within the camming sleeve, the blades can be retracted in a rearwardly oriented direction along the arrow shaft during inflight.          The blades can be retained in a forwardly oriented dir-ection by a frictional engagement means, an elastic or frangible band, slotted frangible cap or the like.
