Abstract: The method of forming a tow of filaments and the tow formed by said method wherein a bundle of elongated elements, such as rods or wires, is clad by forming a sheath of material different from that of the elements about the bundle and the bundle is subsequently drawn to constrict the elements to a desired small diameter. The elements may be formed of metal. The bundle may be annealed, or stress relieved, between drawing steps as desired. The sheath may be formed of metal and may have juxtaposed edges thereof welded together to retain the assembly. The sheath is removed from the final constricted bundle to free the filaments in the form of tow.

Abstract: This invention comprehends a machine for producing camouflage nets. Different camouflage garnish patterns are secured to a net in a preselected and predetermined manner on a repetitive basis. Also, comprehended is a method of making a camouflage net by providing different shape camouflage garnish pieces that are applied to a net at predesignated work stations.

Abstract: This invention contemplates a method and apparatus for taking fine metal fibers having a diameter range from .5 microns to approximately 150 microns and cutting the fibers into precise short lengths. The method and apparatus utilized first moistening tows of metal fibers, unwinding the tows from spools and positioning them into tow bands, stiffening the ribbon made from the tow bands, and cutting the fibers to desired precise lengths in order to prevent cold welding or deformation of the ends of the fibers during the cutting operation. Materials that may be used for stiffening the fibers include starch, PVA, ice, etc.

Abstract: A particle laden gas stream is cleaned by passing it through an all metal fabric including a base with pile fibers connected to the base. The flowing gas forces the pile fibers to lie down upon each other to form a depth filter media adapted to entrap fine particles. This depth filter media is cleaned to remove entrapped particles by passing air through the fabric in a direction counter to the direction the particle laden gas flows through the fabric. Consequently, the pile fibers tend to open and extend outwardly from the base, permitting entrapped particles to be carried by the air from the fabric. Apparatus including a tubular element made of an all metal pile fabric is also disclosed. The tubular element has associated with it one or more nozzles adapted to blow air through the fabric along an incremental portion of the tubular element. Consequently, a small portion of the fabric is cleaned while simultaneously the remainder of the fabric filters particles from the gas stream.

Abstract: A bowling pin structure and method of forming the same wherein the cheek portions of the pin are molded to define controlled density wood fiber and binder resin materials secured about a core. The assembly is machined to define the desired bowling pin body configuration. The cheek material is compressed to provide a preselected density distribution to provide high durability and controlled scorability while maintaining the overall weight approximately that of conventional wood pin materials.

Abstract: A method of making a flocked fabric wherein metal flock fibers are secured to a base. The fibers may be secured as by adhesive, metal fusion bonding, etc. The flock fibers may be metal fusion bonded to each other, may be maintained in spaced relationship, may be provided in tufts, etc.

Abstract: This invention comprehends torsional strengthening of two-phase metal materials. One application of the torsionally strengthened material is in the field of springs wherein the energy storage capacity is increased. The invention provides for methods and processes for increasing the torsional strength of two-phase metal materials. Also comprehended is an apparatus that provides the increased torsional strength by its novel combination of machines.

Abstract: This invention comprehends a machine for producing a composite laminate structure wherein one layer is a base material, such as a non-woven fabric, a second layer, interspersed with the first layer, is substantially a two dimensionally randomly oriented fiber layer. The fibers are bonded to the first layer by resin which is applied from underneath the first layer so as not to disturb the orientation of the fibers. Also comprehended is a method of making such a composite laminate structure.

Abstract: The specification describes a molten carbonate fuel cell electric energy source incorporating a novel pair of electrodes comprising a pair of permeable thin metallic films painted on a magnesia electrolyte matrix and a plurality of fiber metal wicks flocked onto the films. During operation, the molten carbonate electrolyte permeates the wicks, which extend into the gas manifolds, to provide very large surface areas for three-phase fuel cell reactions covered by thin films of electrolyte supplied by large reservoirs in the wicks to minimize cell overvoltage.In addition to the preferred embodiment, a process for fabricating fuel cells and electrochemical electrodes is described. Also, applications to other types of fuel cells, batteries and electrochemical systems are described.

Abstract: An amusement device for use in simulating some of the essential competitive features of the Oriental martial arts such as karate, jujitsu and aikido is described. The preferred embodiment comprises a pair of identical pictures of combatants -one picture for each participant. The picture of each combatant camouflages a series of 10 lights, each light being located at a key attack/defense point on the combatant's body. At the start, one of these ten lights is turned on and the participants each try to hit their light to turn it off. The first "hit" causes both first lights to extinguish and a second light in each series to illuminate. The player to make the first "hit" gets a scoring credit for that "hit." The participants strike at the second light and so on as the 10 lights are sequenced in a pseudo-random order. The game continues for a predetermined period and at the end a winner is determined by comparing the number of "hits" made by the players.

Abstract: A bowling scoring system having a single computation means for computing scores bowled on any of a plurality of lanes and which (1) includes an error correction system; (2) computes anew at the end of each frame a team total score which will reflect any corrections made to bowlers' scores, including all pinfall actually earned by bowlers on a team and will be for a discrete team frame whether or not all bowlers on the team are bowling in the same frame; (3) is adapted to be selectively conditioned to score league bowling on all lanes, open bowling on all lanes, or league bowling on some lanes and open bowling on other lanes; (4) includes logic which anticipates the nature of a subsequent readout and conditions the readout device for the readout in advance of the operation; (5) incorporates a separate center for readout for each lane to be scored; and (6) is formed of a number of electronic registers fabricated primarily of semiconductor components.

Abstract: An apparatus for counting and indicating the number of bowling games played in a bowling establishment having a plurality of lanes, each equipped with an automatic pinsetter. A count of eleven feedback counter provides a single output signal in response to eleven frame input signals each of which may be taken from the various automatic pinsetters each time a frame is played on any one of the lanes to convert frame signals to game signals. The output signal from the counter is then fed to a totalizer indicator which indicates the number of output pulses received as indicative of the number of games played in the bowling establishment.

Abstract: An ultrahigh strength material made from ordinary 18-8 stainless steel has a tensile strength in excess of 400,000 p.s.i. The method of producing the ultrahigh strength is accomplished by thermo-mechanical operations. The material can have any desired geometric cross section configuration and is adaptable for use as a spring material.
