Abstract: LIGHTWEIGHT CONTAINER          ABSTRACT OF THE DISCLOSURE           A novel pressure holding container formed of thin sheet metal of the order of between 10 and 4 mils wherein the container has a bottom portion and a top portion, the bottom portion having a body and an integral bottom, and in one embodiment having a necked-in upper end of the body which tightly fits into a lip portion of the lower end of the top portion and is adhesively bonded thereto and where-in the upper portion of the top portion has a toro-conical shape which under pressure wants to expand it into a spherical shape and thus through beam loading on the lip portion imposes compressive stresses thereon and holds in compression the adhesive which is interposed between the lip and the annulus of the necked-in portion of the body which is loaded in tension by the internal-pressure in the container.  In another embodiment of the invention, the body has no necking-on at its upper edge and is of uniform diameter from end to end and is tightly fitted into the lip of the upper portion and adhesively bonded thereto.  The joint in each embodiment has thin lapped metal sections which deflect and transmit lateral loads imposed on the body and/or lip and thus attenuate the forces without imposing peeling forces on the adhesive.  The conical sections are either stepped or smooth for different force loadings particularly in the application of different types of closures thereto.                          * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE         A corrosion protection product for protecting an outer covering on a metal body from corrosive under-mining, the method of providing corrosion protection with the use of such product, and the resulting corro-sion protection structure.  The corrosion protection product is an inner protective material used in connec-tion with a metal body having an outer surface, pores communicating with the outer surface, and a covering of outer protective material that is bonded to the out-er surface and bridges over the pores.  The inner pro-tective material is a liquid medium, preferably oil, which is substantially impervious to atmospheric corro-sive agents, having therein a suspension of finely di-vided particulate material, preferably paint pigment. The inner protective material is introduced into the pores, and any of the inner protective material that may remain on the outer surface is selectively removed, leaving bodies of the inner protective material in the pores.  Some of the finely divided particulate material is impelled inwardly relative to the liquid medium in the pores so as to substantially seal off small inner channel portions of the pores and thereby stabilize the location of the bodies of inner protective material in the pores, both pending application of the outer cover-ing and after the application of the outer covering over a long operational life of the resulting corrosion pro-tection structure, so that the inner protective material is properly located for optimum protection of the outer covering from corrosive undermining.

Abstract: ABSTRACT OF THE DISCLOSURE     An igniter for Jet  and other internal  combustion engines is  disclosed.  A  ceramic  insulator  containing  a substantial  proportion  of  silicon   nitride  is  disposed annularly within the  shell  of the  igniter so  that  spark discharge  occurs  along  a surface of  the silicon  nitride insulator adjacent the spark gap between  a center electrode and  a ground electrode. An igniter  having  such a  silicon nitride insulator is particularly  adapted for service under conditions of  severe thermal,  mechanical,  and  electrical stress, in an  engine  having a high  voltage, (e.g., 10,000 volts  or  more),  high  energy  (e.g.,  up  to  20  joules) ignition system.  Use of silicon  nitride  as an  insulating material   in  such  igniters   eliminates  health   hazards associated with  toxic beryllium oxide insulators previously used,  while  producing  an  insulating  surface   far  more durable than one made of alumina.

Abstract: SUNFLOWER BUTTER SPREAD AND PRODUCTS THEREOF INCLUDING A PRETREATMENT OF THE SUNFLOWER SEEDS AND THE LIKE            ABSTRACT OF THE DISCLOSURE         A process is disclosed whereby the objectional grey-green discoloration is removed from sunflower seed, meal and the like prior to roasting.  The system utilizes a pretreatment of the seeds, meal and the like by chemical and/or physical means after dehulling and prior to roasting by the addition of acidic compounds that significantly affect the discoloration reaction such as those reactions that are catalyzed by enzymes or oxygen.  Similar results may be obtained by the addition of reducing agents which serve to prevent the oxidation of the caffeic and chlorogenic acids or can convert the ortho-quinones back to the reduced state.          The process can also be effected by the addition of bleach-ing agents, blocking agents, compounds which result in the breakdown of the ortho quinone-protein complex, antioxidants, compounds which result in the hydrolysing of the chlorogenic acid or by the addition of compounds which cause the in-activation of the enzymes.  Finally the process may use physical treatments.  In all cases the roasting process which follows the pretreatment, is found to stabilize the reaction and prevent the discoloration from recurring.  The pretreated and roasted material can subsequently be used in the manufacture of Sunflower butter spread and products thereof.

Abstract: ABSTRACT OF THE DISCLOSURE          A pneumatic punch for paper, and particularly photographic paper.  The punch comprises a cylinder having a piston seated within, to be pneumatically driven between upper and lower limits in the cylinder chamber.  For this purpose, actuation and retraction air inlet ports are provided through the wall of the cylinder, the ports being separated by the piston against fluid communication within the cylinder chamber between the ports.  An elongated guide of constant, circular cross-section is secured centrally to the piston on the side thereof exposed to the air from the retraction air inlet port.  An elongated punch of circular cross-section is concentrically secured to the free end of the guide.  A central relatively restricted air passageway extends from the actuation air inlet port side of the piston, passing through the piston, guide and punch.  A die co-operates with the punch, the die having a body rigidly associated with the cylinder and having a slot of circular cross-section to re-ceive the punch.  A space is provided between the punch, when the piston is at its upper limit, and the entrance to the slot of the die to receive and permit passage of paper to be punched.  During opera-tion, air pressure from the actuation air inlet port drives the pis-ton to its lower limit as air is passed through the central air pas-sageway of the piston, guide and punch to force a slug of punched paper on through the slot.  Such a punch avoids the need for sole-noids, often found in prior art punches used for photographic paper and permits smooth operation, ready adjustment and combined pneumatic punching and removal of slugs of paper produced by the punching process.

Title: Apparatus for providing an indication of fluid flow  through a fluid metering device
Inventor: BASH IGNATIUS F
IPC: G01F1/115
Filed: 1982-06-21
Granted: 1984-11-13
Abstract: Abstract of the Disclosure The disclosure is directed to an apparatus for providing an indication of fluid flow through a fluid metering device of the type in which motion or position of a permanent magnet, internal to the (sealed) fluid metering device, is related to fluid flow.  Operation is by means of sensing, through the housing of the fluid metering device, the external magnetic field of the permanent magnet.  Sensing is accomplished by a sensor means, secured to the fluid metering device.  The sensor means typically comprises one or more coils, or windings, on a core of magnetic material.  An ac excitation current, supplied to an excitation winding, produces an alternating magnetic intensity (H) in the magnetic material.  Under the influence of the external field of the permanent magnet, nonlinearities in the magnetic material produce, in a pickup winding, a first electrical signal that is related to the position of the internal permanent magnet.  Also disclosed is a detection means, which includes electronic circuitry for rectifying the first electrical signal to produce a second electrical signal that is indicative of fluid flow.  Typically, the detection means produces a pulse, or a voltage transition, each time a magnetic pole of the permanent magnet moves by the sensor means.  These pulses, or voltage transitions, can then be counted to provide an indication of cumulative fluid flow through the fluid metering device.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for conveying flat goods having one face covered with a liquid layer comprises two roller trains for, respectively, delivering the goods to and removing the goods from, a generally vertically orbiting chain having a first group of fork-shaped carriers attached thereto, and at least one generally horizontally conveyed, parallelogram-guided, fork-shaped carrier. The rollers of the roller trains are supported each only at one of its roller ends. The carriers of the first group have prongs which pass through gaps between adjacent rollers of the roller trains. Likewise, the prongs of one of the two carrier systems (the first group and the horizontally conveyed carrier or carriers) pass through gaps between adjacent prongs of the other system. The two carrier systems are driven from a common motor (variable drive). The arrangement and kinematics is such that the hori-zontally conveyed fork overtakes each fork of the first group shortly before and after the latter carrier passes through an upper direction-reversing, preferably arcuate stretch.       The goods, e.g. plates to be conveyed are transported into the range of the carriers of the first group passing up-ward and lifted off the rollers by the next-ascending fork thereof. Just prior to reaching the upper direction-reversing stretch, the preponderantly horizontally conveyed fork over-takes the ascending fork and lifts the plate off the latter fork and carries it transversely to the descending stretch, where this preponderantly horizontally conveyed fork over-takes in downward direction a descending fork and deposits the plate it has carried, on the overtaken carrier of the first group. The latter carrier then deposits the plate on the other roller train which removes it from the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE     This   specification  discloses  a  process   for manufacturing  a plurality  of  articles  in which  the articles are stacked generally one upon another during a portion of the manufacture thereof.  The process is initiated by selecting a substrate from a plurality of substrates.  A pattern of material with a first height dimension is deposited on a  selected surface of the substrate.  The pattern of material contains at least one component which is heat fusible with the substrate when heated to a fusion temperature.  A plurality of spacing dots having a height greater than the first height are deposited on a surface of a substrate.  The plurality of spacing dots are out of registry with the pattern of material on the substrate and are formed from  a  radiation  curable  material  which  is  heat decomposable into components which are nonreactive with the substrate.  The radiation curable material is cured thereby to form a plurality of spacing dots.  The cured spacing dots are capable of supporting weight thereon. The substrate with the cured supporting dots thereon is stacked to form a stack of  such substrates.   Other substrates are similarly processed and stacked until a complete  stack  of  such  substrates  is  formed.   A completed  stack  of  such  substrates  is  moved  to  a heating  lehr  which  is  operated  at  a  temperature sufficiently high to heat the pattern of material to its  fusion temperature.   The stack of substrates is unstacked one at a time and the unstacked substrates are  passed  through  the  lehr.   In  this  manner  the fusable pattern of material is fused to the substrate and the plurality of spacing dots are decomposed into components nonreactive with the substrate.
