  • Patent number: 5676646
    Abstract: A flow through apparatus for implanting molecules into living blood cells of a patient, comprises a housing including an elongated flow through chamber having an inlet and an outlet at opposite ends thereof, a pair of elongated spaced apart parallel electrodes disposed between the inlet and the outlet for fluid to flow therebetween, a continuous flow shunt including a pump for withdrawing blood from a patient, passing it through the flow through chamber between the electrodes and returning it to the patient, apparatus for injecting a predetermined quantity of fluid medium carrying preselected molecules into the blood after it has been drawn from the patient and before it passes through said chamber, and an electrical source for applying a predetermined electric signal of a predetermined amplitude and duration to the electrodes for generating and repeatedly applying electric fields of a predetermined amplitude and duration to the flow of the mixture of blood and fluid medium in order to make the walls of prese

  • Patent number: 4511094
    Abstract: A winding machine for manufacturing transformer cores includes a ribbon-dispensing assembly which travels in a predetermined path about a stationary mandrel to deposit successive layers of ribbon upon the mandrel under controlled tension while applying transverse pressure to the peripheral surface of the winding to press air from between the layers. In the preferred embodiment, a counterbalanced rotating track engages the ribbon-dispensing assembly as it travels around the mandrel. The ribbon dispensing assembly is preferably transported by a chain drive.

  • Patent number: 4456139
    Abstract: A tamper-proof closure arrangement for a container includes in one embodiment a seal applied to seal receiving surfaces of the container and closure cap such that the seal is applied internally of the closure cap without removing the closure cap and is irreversibly damaged by any attempt to remove the closure cap, the seal being visible through the closure cap to provide a visual indication of tampering. In an alternative embodiment, the seal is fixed internally of a disposable cap which is mounted on an associated container to overlie a reusable closure cap. The seal is visually observable through the disposable cap and is formed in contacting relation against a three-dimensional surface on the reusable cap such that any attempt at removing the disposable cap irreversibly damages or deforms the seal to provide a visual indication of tampering.
