Abstract: An apparatus and method for utilizing energy, in which the apparatus may be used for generating electricity or as a heat pump. When used as an electrical generator, two gas concentration cells are connected in a closed gas circuit. The first gas concentration cell is heated and generates electricity. The second gas concentration cell repressurizes the gas which travels between the cells. The electrical energy which is generated by the first cell drives the second cell as well as an electrical load. When used as a heat pump, two gas concentration cells are connected in a closed gas circuit. The first cell is supplied with electrical energy from a direct current source and releases heat. The second cell absorbs heat. The apparatus has no moving parts and thus approximates a heat engine.

Abstract: Two novel hybridoma cell lines, ATCC #HB-8397 and ATCC #HB-8398 produce monoclonal antibody monospecific to a single determinant shared by a set of three closely related cytoplasmic antigens of Candida albicans. The antigens have molecular weights of 120-135 Kd, 48-52 Kd, and 35-38 Kd. The hybridomas are formed by fusing splenocytes from immunized BALB/c mice with SP2/O-Ag 14 myeloma cells. Monoclonal and monospecific, polyclonal antibodies to these cytoplasmic antigens find application in the immunodiagnosis of Candida infections.A procedure is provided for preparing partially purified cytoplasmic antigen of pathogenic Candida species for administration to splenocyte-donating mice. Also provided is a method for the biochemical purification of cytoplasmic antigen of a pathogenic Candida species used for the preparation of monoclonal and monospecific, polyclonal antisera thereto.

Abstract: A strain of Neisseria gonorrhoeae ATCC 31953 is described which is abnormal in that it has characteristically poor growth on chocolate agar at a temperature range of about 30.degree. C. to about 37.degree. C. in a CO.sub.2 atmosphere suitable for growth of N. gonorrhoeae. This strain is resistant to nalidixic acid at the 5-10 mcg/ml level and resistant to streptomycin at the 1000 mcg/ml level or greater. N. gonorrhoeae ATCC 31953 is a test strain suitable for use in the method described for the laboratory diagnosis of gonorrhea.

Abstract: A system is described for the conversion of the energy in the wind over oceanic regions into hydrogen which can be used as a supplement to or replacement for fossil fuels. The system is based on the use of modified sailing vessels which serve as water electrolysis plants. In operation, the wind propels the vessel through the water in the manner common to all sailing vessels except that the vessel in this system does not carry a mast and does not need the ballasting characteristic of conventional sailcraft. The propulsion of the vessel causes an immersed screw propeller to power an electromagnetic generator, the electric current from which electrolytically decomposes water into hydrogen and oxygen. The hydrogen is stored on board the vessel by allowing it to combine with suitable metal alloys such as the Fe-Ti alloys to form a hydride.

Abstract: A process is described for enhancing the immunogenic response of mammals. N-acylated-D-glucosamines were administered parenterally in the form of liposomes to mice at or before the time of administration of an immunogen or radiation, with the result that comparable or superior enhancement of the immune response was observed for these glycolipids when compared to LPS in assays measuring anti-SRBC or HGG hemagglutinin titers. The radiation protective effect of some of the synthetic adjuvants gave a definite protection, with up to 40% of lethally irradiated mice (700 R) surviving.

Abstract: A group of novel, low temperature liquid crystalline compounds with terminal, primary or secondary amino polar electron donating groups are disclosed. These include, for example, p-alkyl-or alkoxy-phenylcyclohexanes, bicyclohexyls or biphenyl ring systems, substituted at the p' position with alkyl primary or secondary amines, of which one example is p-(4-trans-n-pentylcyclohexyl)benzylamine.

Abstract: An electrolytic cell wherein one of the elements is comprised of a canal clathrate complex of benzophenone and a polyiodide salt of a cation from a group consisting of potassium (K.sup.+), sodium (Na.sup.+), cesium (Cs.sup.+), lithium (Li.sup.+), ammonium (NH.sub.4.sup.+), rubidium (Rb.sup.+) and tetraalkylammonium (R.sub.4 N.sup.+ where R is an alkyl group of less than five carbons). This complex functions through its tunnel-like dispositions of the cations, having certain unfilled sites and certain other sites occupied by the CHCl.sub.3 molecule, as a solid fast ion conductor. The same composition, again apparently because of the canal clathrate complex crystal structure, is adapted, by virtue of its electronic conductivity to function as an electrode in an electrolytic cell.

Abstract: A method and apparatus is provided for direct conversion of ocean wave energy into electric power. The apparatus has no moving parts, and uses wave motion to vary the pressure of hydrogen gas in one of the cavities of a two-cavity chamber. The resulting imbalance of pressures in the cavities is relieved by conduction of hydrogen ions through a protonic conductor separating the cavities, and by conduction of electrons through an external circuit, enabling hydrogen gas to be formed on the low-pressure side of the chamber. The conduction of electrons constitutes a usable electric current. Virtually no hydrogen is consumed in this power generation process.

Abstract: A liquid crystal composition for improved electro-optic displays. The composition undergoes an electrically induced cholesteric-nematic phase transition and includes fluorescent materials which are excited by ultra-violet radiation. In the cholesteric phase of the composition, the fluorescence is much stronger producing sufficient contrast to render the display visible in the dark.

Abstract: Irradiation of collected S.sub.4 N.sub.4 decomposition products with light or radiation in the .gamma. to visible range enhances the initiation of polymerization of the decomposition products to produce polysulfur nitride, which is typically conductive and usually referred to as (SN).sub.x. Irradiation of a masked coating of collected S.sub.4 N.sub.4 decomposition products and completion of polymerization thereof and removal of non-irradiated, non-polymerized portions thereof will result in an electrically conductive coating disposed in a preselected pattern. S.sub.4 N.sub.4 decomposition products may also be dispersed in a matrix, e.g. a photographic emulsion which is transparent or partially transparent to light, or which may be rendered partially or selectively transparent or opaque. This might be useful, for example, for imaging applications, or for producing a selectively transparent pattern for subsequent photoinduced initiation of polymerization of the S.sub.4 N.sub.4 products.

Abstract: A pair of active probes and a datum probe are affixedto the patient, and the active probes' signals are coupled to a preamplifier involving both common mode rejection and differential amplification. The information bearing voltage levels are coupled to a voltage controlled oscillator, the output of which bears information in the form of frequency variations. A photocoupler isolates the patient from unwanted feedback, and drives a phase locked loop which demodulates the signal back to an information bearing voltage. The derivative of the voltage signal is taken, is separated by polarity to correspond to the direction of eye motion, and is coupled to the EEG, thereby representing nystagmus velocity.

Abstract: Liquid crystal mixtutre of donor and acceptor molecules, the first consisting of a liquid crystal compound having an unshared electron pair (the donor) and the second generally consisting of an electron receptive compound such as a p-cyano-p'-alkyl- or alkoxy-substituted bipheny liquid crystal compound (the acceptor); together these compounds form a molecular complex with improved physical properties, including particularly a broader mesophasic temperature range, then would be expected from a simple combination of such liquid crystals.

Abstract: Cellular organelles, examples of which are mitochondria, microsomes and chloroplasts, are bound in an active state on a substantially inert and insoluble support surface, examples of which are alkylated glass, kaolin, talc, silica, ferrites, alumina, and some alkyl substituted high molecular weight polymers. Binding between the support surface and the organelle is accomplished by adsorption of the isolated organelle onto the support surface. Immobilization in this manner does not affect the functional behavior of the organelle. These systems have utility for the synthesis of specific chemical substances.

Abstract: Cumulative temperature dosimeter utilizes a temperature dependent reaction in a cholesteric liquid crystal composition to produce a color change indicative of temperature exposure over a period of time.Typically, the composition includes, as a solvent, a cholesteric liquid crystal, such as a mixture of p-methoxy-p'-n-butyl-azoxybenzene, cholesteryl nonanoate, cholestyl chloride, and cholesteryl oleyl carbonate. One or more solutes are included, the solutes being reactive at a rate which is temperature dependent, to cause either generation or consumption of mesogenic compounds. In turn, the pitch of the solvent, observable as a visible color change, is affected in proportion to the cumulative temperature exposure of the composition.
