  • Patent number: 5695175
    Abstract: A joint, particularly for use with banister assemblies, comprises a ball (14) fixed into position within a socket (13). The balls (14) formed at either end of a plurality of balusters (12), and sockets (13), formed in a base rail (10) and hand rail (11) are preformed at a work shop or factory and subsequently used for construction of a banister assembly. During the construction of such an assembly, the base rail (10) is fixed into position and the hand rail (11) placed in parallel, vertically spaced-apart relation to it, supported loosely by newel posts at either end. Next, balusters (12) are inserted between the base rail (10) and hand rail (11) by inserting a bottom ball of each baluster (12) into the base rail sockets (13) and adjusting the hand rail (11) to enable insertion of the upper balls into the hand rail sockets (13). Once all balusters are in position, the hand rail (11) can be firmly fixed into place.

  • Patent number: 5654013
    Abstract: A method for the topical treatment of skin affected with acne, rosacea, or a combination thereof. Sodium chloride in a substantially pure form is topically applied to the affected skin by gently gliding the sodium chloride over the affected skin in a manner insufficient to cause abrasion and debridement of the affected skin. A solid block of about 98% to about 100% by weight sodium chloride free of a carrier and/or free of other topical acne-treatment medicaments and/or free of other topical rosacea-treatment medicaments should be used. The applied sodium chloride is left on the skin. Preferably, the affected skin is pre-moistened with water from shaving, bathing, splashing water on the skin, and the like prior to gliding the sodium chloride thereon.

  • Patent number: 5637339
    Abstract: A tar-depleted liquid smoke having total water miscibility, and related method for making same. The tar-depleted liquid smoke may be made from commercially existing liquid smoke products, for instance, by treating such a commercial product with a column filtration process using activated carbon particles packed in the column. The resultant tar-depleted liquid smoke typically will have a phenols reduction of about 10% to about 90% compared to the commercial starting product of liquid smoke. In an alternative embodiment, the tar-depleted liquid smoke made from carbon contact is then vacuum concentrated so that it has a phenols content greater than that of the commercial starting product of liquid smoke, but the concentrate will still be totally water miscible.

  • Patent number: 5626627
    Abstract: A method in electroconvulsive therapy (ECT) to use ictal EEG data for clinical determination of the adequacy of an induced seizure in a patient. The method includes employing an ECT device to apply electricity to the patient in an ECT session to induce seizure activity. The electroencephalographic (EEG) data is detected during the seizure and selected EEG data parameters are derived therefrom. Next, the likely adequacy of the induced seizure is computed by comparing the selected EEG data parameters of the patient to ictal EEG data parameters wherein the adequacy of the corresponding seizure or seizures is known, and the computed likely therapeutic adequacy of the induced seizure is displayed.

  • Patent number: 5607166
    Abstract: A fluid seal device comprising an annular body having an inner side, an outer side, a closed end face and an at least partly open end face wherein the at least partly open end face defines a first radial sealing area protruding outwardly from the outer side and a second radial sealing area protruding outwardly from the inner side of the annular body so that the plane defined by the first radial sealing area is spaced apart a further distance from the closed end of the annular body than the plane defined by the second radial sealing area. The at least partly open end face of the fluid seal device defining the first and second radial sealing areas is formed of a less rigid elastomeric material than the remaining portion of the annular body of the fluid seal device so that the radius of the second radial sealing area will tend to hinge and roll and to thereby maintain a generally constant resistance during movement of an element in contact therewith.

  • Patent number: 5604834
    Abstract: A method of midspan or end entry accessing of one or more selected optical fibers carried by an optical ribbon fiber. The top and bottom surfaces of a first selected span of the optical ribbon fiber are friction abraded to initiate delamination of the bond between the optical fibers and the matrix encapsulant. The delamination is completed by applying a rolling force to the circumference of the first selected span, and the delamination is then propagated by introducing the first selected span into the bore of a die element and urging the die element along a relatively longer second selected span of the optical ribbon fiber. With the delamination completed, the tip of an elongated tool is inserted through the encapsulant within the second selected span and between one or more selected optical fibers and the remaining optical fibers within the optical ribbon fiber.
