  • Patent number: 4031480
    Abstract: A circuit arrangement for the ungrounded transmission of signals through testing points in communication systems with the aid of high-frequency oscillations. The high-frequency oscillations are controlled on the one side of the testing point and are rectified on the other side of the testing point. The rectified signals are utilized to reproduce the signals again. A resonant circuit is adjusted to the high-frequency oscillations and is galvanically separately coupled to a high-frequency generator. The resonant circuit is also connected to a modulation circuit and to the input of the testing point. The resonant circuit is coupled inductively to a demodulation circuit which forms the output of the testing point.

  • Patent number: 4029582
    Abstract: A semipermeable polymeric membrane which essentially consists of modified poly (arylether-sulfone) having halomethyl groups and/or quaternized nitrogen atom-bearing groups. The membrane can be prepared by casting the polymer solution in a selected solvent or a mixture of suitable solvents on a surface, evaporating a portion of the solvent, and immersing the resulting film into a suitable non-solvent. The membrane is excellent in performance, such as water flux, and permeation selectivity, so that it can be used as a reverse osmosis membrane, an ultrafiltration membrane, and the like.

  • Patent number: RE29265
    Abstract: Plastic molding machine, primarily adapted for generating and molding a closed-cell foam plastic material. The foam is generated by introducing a gas inert to the plastic material into a granular mixture of same so that the gas is thoroughly intermixed among the granular particles. The gas is then held under pressure while the granular particles are reduced to a flowable material, said pressure being sufficient to assure that the gas will not be expelled therefrom during the plasticization process. In one preferred embodiment, gas is mixed into the granular plastic in a hopper and held therein under pressure as said granular material is fed into a screw and plasticized thereby.The plastic material is then conducted at a relatively low pressure, such as that generated by the extrusion machine used for plasticizing the material, through a branched system past a check valve in each branch of said system, to an injection assembly.
