Abstract: Method and apparatus to remove wrinkles in a running web of material by the use of rotating members on the selvedges of the fabric in conjunction with vacuum pressure to urge the selvedges outward and to slightly overfeed the fabric.

Abstract: A process for the manufacture of 1,3,5-triaminotrinitrobenzene having a large crystal size by aminating 1,3,5-trichlorotrinitrobenzene with an agent at atmospheric pressure at a temperature of at least about 160.degree. C. with an antioxidant added to the reaction mixture.

Abstract: Improvement in the preparation of open-pored phenolic resin foams by the foaming of intimate mixtures of water-containing phenolic resol resins in the viscosity range of from 1000 to 20,000 cP, low-boiling organic liquids in which the phenolic resol resins are not soluble as blowing agents and acid-containing hardeners, the improvement comprising adding to the foamable phenolic resol resin before or during the preparation of the foamable mixture, 1.0 to 6.0 weight-percent of ethoxylated castor oil and 0.5 to 5 weight-percent of an alkyl sulfate salt of the general formulaC.sub.x H.sub.2x+1 --O--SO.sub.3 --Me.sup.+wherein x an integer from 8 to 18 and Me is an alkali metal or a triethanolamine cation.

Abstract: Method and apparatus for brushing the pile of a pile fabric and removing wrinkles in a running web of the material by the use of rotating members on the selvedges of the fabric in conjunction with vacuum pressure to urge the selvedges outward and to slightly overfeed the fabric.

Abstract: An extrusion die to extrude a water paste onto a web material. The die consists of two separate chambers which equalize the pressure of the water paste prior to extruding same through an elongated slot onto a web of material.

Abstract: Method and apparatus to remove wrinkles in a running web of material by the use of rotating members on the selvedges of the fabric in conjunction with vacuum pressure to urge the selvedges outward and to slightly overfeed the fabric.

Abstract: An improved sculpturing apparatus having an asymmetric blade, improved fabric support means and an improved screen for applying stiffening agent is disclosed. The apparatus allows the fabric support structure to be adjusted to the curvature of the cutting blade to maintain the fabric to be cut into contact with the cutting means.

Abstract: A sabot projectile having a pyrotechnic composition, especially a flare composition, arranged at the projectile body, wherein only a part of the pyrotechnic composition protrudes into a recess adapted to receive the same and provided at the tail of the projectile body. The part of the pyrotechnic composition protruding out of the tail of the projectile body is surrounded by a shell or jacket.

Abstract: An improved sculpturing apparatus having an asymmetric blade, improved fabric support means and an improved screen for applying stiffening agent is disclosed.

Abstract: An improved sculpturing apparatus having an asymmetric blade, improved fabric support means and an improved screen for applying stiffening agent is disclosed.

Abstract: Method to prevent the accidental cutting of the selvedge backing material of a pile fabric being sheared by a rotating cutting apparatus by maintaining the selvedge in a tensioned condition in response to an automatic control which senses the position of the selvedge of the fabric.

Abstract: Apparatus to sense and guide the edge of a backing material having a raised surface. A double sensor is provided to either sense the edge of applied substance or the edge of the backing material or selvedge. The double sensor employs a pair of flag members to vary the pressure of a fluidic sensing device in response to the position of the selvedge to automatically control the position of a selvedge protection device.

Abstract: A device for sculpturing pile fabrics which have been treated by stiffening the fibers thereof in selected regions. The device includes means for advancing the fabric, a support and a blade which severs the stiffened fibers as they pass over the support but allows the unstiffened fibers to deflect away from the blade.

Abstract: Apparatus to prevent the accidental cutting of the selvedge backing material of a loop pile fabric being cut by a rotating cutting apparatus. The apparatus includes a plurality of fingers which engage the selvedge to maintain it in a tensioned condition in response to an automatic control which senses the position of the selvedge of the fabric.

Abstract: A pile fabric manufacturing apparatus having a mechanism to sense and guide the edge of the cut loop pile fabric. A double sensor is provided to either sense the edge of the pile or the edge of the backing material or selvedge to correctly maintain the predetermined position of the fabric.

Abstract: An explosive projectile which comprises a projectile body possessing a hollow compartment for receiving an explosive charge, a rear end surface, a border ring extending rearwardly from the rear end surface. A tracer composition sleeve is secured to the projectile body and possesses a front end surface which sealingly bears at the rear end surface of the projectile body. At least one of said rear end surface of the projectile body and said front end surface of the tracer composition sleeve having a substantially disc-shaped recess forming a substantially ring-shaped sealing contact surface between such rear and front end surfaces.

Abstract: A base fuze for a spinning projectile comprising a firing pin for piercing a detonator cap, a hammer sleeve secured to the firing pin, a self-destruction spring by means of which the hammer sleeve together with the firing pin can be displaced towards the detonator cap. An inertia body is provided for increasing the response sensitivity and is located behind the hammer sleeve. Upon impact of the projectile the inertia body bears directly at the hammer sleeve in order to increase the mass of the hammer sleeve when piercing the detonator cap by means of the firing pin due to the inertia of such inertia body.
