Abstract: FLUID JET PRINT HEAD AND METHOD OF MAKING         Abstract of the Disclosure A fluid jet print head for producing a plurality of jet drop streams of fluid includes a manifold defining an elongated cavity and an orifice plate defining a plurality of orifices, arranged in at least one row, which communicate with the cavity.  A transducer arrangement, including a piezoelectric means, is mounted in the cavity and is spaced from the orifice plate so as to define a fluid reservoir therebetween.  The transducer arrangement further includes acoustic isolation material which surrounds the piezoelectric means and supports the piezoelectric means in the cavity.  The transducer means, when electrically excited, produces pressure waves of substantially uniform wave front which travel through the fluid in the reservoir toward the orifice plate and cause break up into jet drop streams of fluid flowing through the orifices.  The piezoelectric means may include an elongated transducer which defines a plurality of slots extending alternately from opposite sides of the transducer partially therethrough.  Each of the slots is substantially perpendicular to the row or rows of orifices.  The slots prevent wave propagation along the transducer.  Alternatively, the piezoelectric means may include a plurality of transducers arranged in at least one transducer row extending in a direction substantially parallel to the row of orifices.

Abstract: ABSTRACT OF THE DISCLOSURE   The skinning machine of the present invention çomprises a skinning blade having a knife edge presented in a first direction.  A gripping roll is rotatably mounted adjacent the knife edge for grasping the skin layer of the meat and pulling the meat into the blade for separating the skin from the meat.  A feed device is provided above the gripping roll and the skinning blade for feeding the meat to be skinned towards the gripping roll. The feed means includes a chute having an upper end spaced above the gripping roll and a lower end in close proximity to the gripping roll. The meat is fed into the chute from behind the skinning blade.          As the meat passes downwardly through the chute, its directional movement is reversed so that it is moving toward the operator when it exits from the chute and is grasped by the gripping roll. Safety is enhanced by virtue of the fact that the cutting blade faces away from the operator, and further by the fact that the meat is fed into the chute at a point spaced above the gripping roll and the skinning knife.

Abstract: Abstract An improved, essentially scrap-free, solid-phase process for making thermoplastic articles directly from a resinous material powder.  The process can be particularly advantageous in forming large parts by compressing the powder into briquettes, sintering the briquettes, repressing the briquettes when in a heated condition into blanks and then shaping the blanks into a preform which can then be thermoformed into a product such as a container, assuming the blank itself is not the desired end product. Alternatively, sintering can take place after repressing with preheating of the briquette prior to the repressing step.   27,818-F                   -?-

Abstract: METER DRIVE INHIBIT CIRCUIT          Abstract A meter drive inhibit circuit is provided whereby an erroneous jump of the meter pointer upon system power-up or subsequent microcomputer reset operation is inhibited. A pulse generator is utilized to produce output pulses relating to the rate of rotation of a drive shaft in a typical tachometer application.  Such output pulses are provided to a meter drive circuit which in turn provides an output to an electromechanical meter.  Such electromechanical meter will display an output related to the time average value of pulses input to the meter drive circuit.  An inhibit circuit stage is connected to the meter drive.  A microcomputer is utilized to sense the power-up condition of the meter circuit and activate the inhibit stage.  When activated, the inhibit stage will prohibit the meter drive from providing an output to the meter and thereby prevent the erroneous jump of the meter pointer upon system power-up.

Abstract: ABSTRACT      A method is disclosed for producing crystalline ammonium metatungstate from ammonium paratungstate.  The method involves heating the ammonium paratungstate at from about 100°C to about 250°C for from about 1 hour to about 8 hours to remove some ammonia and water, digesting a solution of the heated ammonium paratungstate in water at from about 80°C to about 100°C for from about 2 hours to about 6 hours at relatively constant volume while maintaining the pH of the slurry at from about 4.2 to about 3.0 by addition of ammonia as necessary to form a solution of ammonium metatungstate in water.  The ammonium metatungstate solution is then evaporated to concentrate it.  Any insoluble material is separated from the solution. Ammonium metatungstate is then crystallized from the resulting concentrated ammonium metatungstate solution.
