A watercraft has an abovewater passenger and/or cargo section as well as an underwater propulsion section. The two sections are connected by telescoping struts.

Watercraft

An electrode assembly is mounted in a helmet like headset for use in making multiple electrode contact with the scalp. Each electrode assembly includes an electrode that floats in a cylinder mounted in a pressure responsive drive, which, when under pressure carries the electrode toward the scalp of a patient wearing the headset. Mounted in the cylinder above the electrode and biased away from the electrode is an LSI chip carrying an operation amplifier and a power supply for the amplifier. When the electrode makes contact with the scalp the cylinder continues to drive forward. Back pressure from contact with the scalp overcomes the bias and completes a circuit to turn on the amplifier. The amplifier is connected via wire or a wireless signal transmit system to a computer into which amplified signals are fed.

Enhanced electrode headset

Method and apparatus are provided for use in conducting an electroencephalographic (EEG) test where the apparatus includes a headset suitable for placement on the head of a subject to be tested. A plurality of electrodes are mounted on the headset at pre-determined positions about the headset. The electrodes are preferably mounted to the headset by the use of a resilient material, preferably a resilient wire or plastic mesh which is bonded to both the electrode assembly and to the headset. Each of the electrode assemblies include a separate air cylinder for displacing the electrode in the direction of the subject's head upon the application of additional air pressure into the cylinder. A bellows arrangement is provided within each air cylinder for effecting displacement of the electrode. Means are further provided for dispensing a predetermined amount of an electrolytic material from an external source of electrolyte, through the electrode, to the point of contact between the electrode and the subject's head.

Method and apparatus for conducting brain function diagnostic test

A dummy or starter bar for starting a strand in a continuous casting installation having an open-ended mold is provided with a head which is receivable in the mold. The dummy bar head has a peripheral surface which faces the inner surface of the mold. The dummy bar head further has an end face at least part of which is inclined with respect to the peripheral surface. The end face is directed towards the inlet end of the mold. The dummy bar head is provided with a dovetail-like recess which opens to the inclined part of the end face. The recess enables the strand to become coupled to the dummy bar head and is arranged so that coupling occurs in a manner which permits the strand and the dummy bar head to become detached by relative movement thereof in a direction transverse to the longitudinal axis of the strand. The recess is bounded so as to prevent penetration thereof into the peripheral surface of the dummy bar head and this, in conjunction with the inclination provided for the end face of the dummy bar head, enables the dummy bar head to be readily sealed in the mold. A method of starting the strand involves placing bars of chill material in the recess in such a manner that they are inclined with respect to the inner surface of the mold and that the ends thereof are located in the undercut section of the recess. The molten material introduced into the recess solidifies about the chill bars. The latter serve as an anchor within the solidifying mass thus providing an enhanced connection between the dummy bar head and the strand in the first few critical moments of withdrawal of the strand from the mold.
