Abstract: Apparatus for processing synthetic thermoplastic material, such as sheeting, hollow bodies, and splinters, comprises an upright receiving container, which is adapted to be charged from above, and at least one disintegrating and blending member, which is set with knives and is mounted on the container near its bottom and rotates about the axis of the container. The receiving container has in its side wall an opening which is disposed on the level of the disintegrating and blending member and leads to a screw extruder, which is tangential to the receiving container and directly connected thereto.

Abstract: An improved, more compact microwave equalizer is provided by utilizing a length of coaxial transmission line to which at least a pair of relatively small diameter, flexible, coaxial cable resonant stubs are coupled through film type impedance means. Each coaxial cable stub is disposed adjacent the outer conductor of the transmission line, for compactness, and the length of each stub is minimized by use of high dielectric constant material therein. By shortening the length of each resonant stub and by shunting a capacitor across each resonant stub, the frequencies of the upper and lower band edges of the equalizer's attenuation curve are spread apart, while simultaneously providing the desired operating frequency band. Slots and/or an annular recess provided in the relatively thick outer conductor of the transmission line receive the stubs and the retaining apparatus for the film type impedance means.

Abstract: A microwave attenuator including inner and outer conductors defining a transmission path, and attenuator means extending between the inner and outer conductors and including specifically configured resistive means extending transversely of and electrically connected between the inner and outer conductors.

Abstract: A broad-band variable microwave attenuator wherein outer and inner conductive members define a microwave transmission line, the inner conductive member being interrupted to provide a pair of inner conductor member ends on opposite sides of the interruption, a resistive member extending from the outer conductive member toward the space between the inner conductive member ends, and connector means extending from each inner conductive member end to the resistive member to afford attenuating series and shunt paths.

Abstract: A microwave termination for dissipating substantially all of the energy transmitted through a coaxial line structure which has a body adapted to be connected to the outer conductor of the coaxial line, a center conductor adapted to be connected to the inner conductor of the coaxial line, a dielectric member disposed between the center conductor and the body for maintaining the center conductor coaxially disposed relative to the body, and a cylindrically shaped resistor radially disposed within the body so as to be in electrical contact with the body at its opposite ends and with the center conductor at a central portion thereof. The resistor has a resistive coating which absorbs the energy received by the termination from the coaxial line.
