Filed: 1979-12-05
Granted: 1982-08-10
Abstract: ABSTRACT OF THE DISCLOSURE An improved high-voltage device having a high continuous-current rating, which may include both a fuse and an improved switch. The device has a first, high-current-capacity path and a second, low-current-capacity path surrounding the first path in a compact configuration. Current is selectively commutated from the first path to the second path, which may include a fuse, regardless of the nature of the first path. The improved switch has a pair of normally electrically interconnected contacts. The con-tacts are relatively movable apart along a fixed line of direction to break the electrical interconnection. At least one of the contacts, or a part thereof, defines an enclosed chamber which is pressurized to rapidly drive the contacts apart. The chamber may be pressurized by ignition of a power cartridge therein. The switch may be included in the first path of the device, regardless of the nature of the second path. Preferably, the im-proved device comprises a current-limiting fuse which helically, coaxially surrounds the improved switch in a common housing.

The spraying devices have walls confronting the in-ner surface of the roll shell and at which walls there are formed openings which, during operation, form liquid jets. Oil which is infed to the spraying devices can be heated in a collecting container and/or in a tubular conduit. Tempe-rature regulation of the roll shell can also be accomplished by a throughflow or quantitative regulation by means of valves. If there are present a number of temperature zones in the lengthwise direction of the roll shell then different spray devices can be operatively associated with partition walls, from which the liquid is infed to separate collecting containers. From these collecting containers the liquid is again infed, by means of separate pressure lines, to the individual spray devices.

Granted: 1983-04-26
Abstract: ABSTRACT OF THE DISCLOSURE       Viable tissue such as mammalian islets of Langerhans or liver tissue is encapsulated within a semipermeable membrane which allows the passage of oxygen, amino acids and nutrients needed for maintenance and ongoing metabolism of the tissue, but is impermeable to bacteria, lymphocytes, and proteins having a molecular weight above a selected level so as to exclude poten-tially deleterious large molecules such as immunoglobulins.  By means of the process, and insulin generating system can be pro-duced wherein mammalian islets are maintained in a viable and protected state within the capsule and excrete hormones.  Also, mammalian liver tissue can be encapsulated for use as a body fluid detoxification system.  The encapsulated liver tissue is shielded from plasma protein of the type responsible for immuno-logical rejection and from leukocytes and bacteria, but toxins and nutrients required for maintenance and continued normal meta-bolism of the tissue freely traverse the membrane.  The capsules may be injected into a suitable site in a mammalian body and act as an artificial organ, e.g., and artificial pancreas.  The pro-cess comprises the steps of suspending the material to be encap-sulated in a physiologically compatible medium such as a culture medium containing a water soluble substance which can be gelled into droplets to form discrete, shape-retaining temporary cap-sules, forming a semipermeable membrane about the temporary cap-sules, and optionally, reliquify the gelled interior,  The pro-cess can also be used for encapsulating chemically active sub-stances such as activated charcoal particles and labile biolog-ical materials.
