Patent ES-2082790-T3 (ES)
Inventor: BERMAN MARK
IPC: B32B5/26
Filed: 1989-06-27
Granted: 1996-04-01
Abstract: A nonwoven composite material comprising a meltblown fabric layer of a thermoplastic polymer (12) sandwiched between two prebonded, spunbonded reinforcing fabric layers (14, 16) of a thermoplastic polymer, all continuously-bonded together to form composite material (10). The preferred thermoplastic polymer for both the meltblown and spunbonded layers is polypropylene. The nonwoven composite material contains a minimal number of loose fibers, is highly resistant to the penetration of liquids and would also be expected to exhibit good abrasion resistance, while maintaining tear resistance and softness comparable to non-prebonded materials characterized by discrete bonding patterns. The nonwoven composite material is especially useful as a sterilization wrap for surgical and other health care items.

Date Dec. 13, 1990.The specification discloses a process for producing a ferroalloy in a smelting vessel. A material containing an alloying metal is injected into a molten bath contained in the vessel. A flux, a carbonaceous material and an oxygen-containing gas are also injected into the vessel. A gas which may be the oxygen-containing gas is injected into the molten bath in order to stir it. The rates of injection of the various components are controlled to achieve control of the oxidizing and reducing environment within the vessel consistent with a rapid rate of injection. The material containing the alloying metal is either reduced and incorporated into the metal phase or oxidized and incorporated into the slag. Combustion gases above the molten bath are oxidized to provide further heat to the process. Alloyed metal or slag containing the alloying metal are recovered as product. The process is applicable to the production of ferroalloys such as ferrochromium, ferromanganese, ferronickel and ferrovanadium.

Abstract: Repetitive phenomena cancelling controller arrangement for cancelling unwanted repetitive phenomena comprising known fundamental frequencies. The known frequencies are determined and an electrical known frequency signal corresponding to the known fundamental frequencies of the unwanted repetition phenomena is generated. A plurality of sensors are employed in which each sensor senses residual phenomena and generates an electrical residual phenomena signal representative of the residual phenomena. A plurality of actuators are provided for cancelling phenomena signals at a plurality of locations, and a controller is utilized for automatically controlling each of the actuators as a predetermined function of the known fundamental frequencies of the unwanted repetitive phenomena and of the residual phenomena signals from the plurality of sensors. In this arrangement the plurality of actuators operate to selectively cancel discrete harmonics of the known fundamental frequencies while accommodating interactions between the various sensors and actuators.
