Abstract: A process for treating a textile web includes applying a first treatment agent to the web. The web is moved in an open configuration over a contact surface of an ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of the first treatment agent through a first extent of the thickness of the textile web. A second treatment agent is applied to the web. The web is moved in an open configuration thereof over a contact surface of an ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of the second treatment agent through a second extent of the thickness of the web. The second extent is different than the first extent.

Abstract: Bevel gears having a carbon content of at least about 0.4% by weight, preferably 0.5% by weight are manufactured by a process which includes forging a steel blank having a carbon content of at least 0.4% by weight until a bevel gear precursor having essentially the tooth configuration and dimensions of the desired product gear is obtained, and hardening the teeth of the gear precursor by induction heating without machining of the teeth. The initial forging is precise enough so that no further machining of the teeth is required. This requires forging to a tolerance specified in AGMA class 6. The gear is then induction hardened, first by preheating at a lower frequency, say 10 KHz, then induction heating at a higher frequency, say 50 KHz, in order to obtain a desired hardness profile. The desired hardness profile includes the surface hardness of at least 50, preferably 60, on the Rockwell C scale and a core hardness not over Rockwell C 45, preferably from Rockwell 25 to Rockwell 40.

Abstract: A method and apparatus for machining a workpiece from a hardened unmachined part includes the use of non-rotating centers in a turning machine, on which the workpiece is mounted. The shape of the dead centers permits less force to be used in support of the workpiece for reducing friction between the rotating workpiece and non-rotating centers, while exerting a maximum amount of radial holding force to reduce runout in the machining operation. Lubrication can be supplied through the dead centers to further reduce friction and/or an anti-friction coating may be applied to the contacting surface of the centers for this purpose. Machining of the hardened part may be controlled by CNC equipment.

Abstract: A broadhead for connecting to the end of an arrow comprises a shaft having a longitudinal cylindrical shaped body and a plurality of blades pivotally attached to a blade holder that is slidably mounted upon the shaft. The blades are resiliently held in a retracted position during flight by at least one O-ring. When the broadhead impacts against an animal, the blade holder is slidably forced rearward allowing the blades to pivot outward into an extended position.

Abstract: A method for machining a part with gear teeth onto an unmachined part to form drive pinion gears is disclosed. A center bore is formed at one end of the part and receives a tool center to mount the part for machining. The center bore includes a plurality of lobes which are in point contact with the lathe center, allowing adjustment between the unmachined part and the lathe center. Drive apertures are formed radially outwardly of this center bore to receive drive pins from the machine tool. Most preferably the drive apertures are slots which provide clearance, facilitating the alignment of the drive pins in the drive apertures.

Abstract: A composite nonwoven elastomeric web material, and method of forming such material, as well as a nonwoven elastomeric web material and method of forming such material, are disclosed. The composite web material is provided by hydraulically entangling a laminate of at least (1) a layer of meltblown fibers; and (2) at least one further layer, preferably of at least one of pulp fibers, staple fibers, meltblown fibers, and continuous filaments, with or without particulate material, with at least one of the layer of meltblown fibers and the further layer being elastic so as to form an elastic web material after hydraulic entanglement. The nonwoven elastomeric web material is provided by hydraulically entangling a layer of meltblown elastomeric fibers. The material formed can be cloth-like with smooth surfaces, and with isotropic elasticity and strength. Different texture properties, including a corrugated stretchable fabric, can be provided by pre-stretching and then hydraulically entangling while stretched.

Abstract: Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can be hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance.
