Abstract: Apparatus for processing and analyzing various liquids, such as blood ser includes an indexable table for supporting a plurality of liquid sample containers. A probe is inserted into each sample container in succession. During probe insertion, a portion of the sample to be analyzed is withdrawn by the probe from the respective container and moved to a station where it can be analyzed and tested. The probe is then moved to a station where it can be washed prior to insertion into the next sample container. The drive mechanism for the apparatus is characterized by the fact that all indexing mechanisms and actuator cams are mounted on a single rotatable shaft and arranged such that each periodic function performed by the mechanism is directly coupled to the rotation of the shaft.

Abstract: The non-impact dot matrix printer is a high speed alpha-numeric, electric spark discharge printer that utilizes a rotating perforated dielectric belt in cooperative association with a laminar stack of insulated electrical conductors to control electric spark discharge printing on an electrical conductive erosive surface of a recording medium. The belt is disposed between the laminar stack and the conductive surface of the recording medium, and alpha-numeric characters are printed on the printing surface by applying a controlled source of voltage between the printing surface and the stack to cause spark discharging through the perforations in the rotatable belt, under the overall control of appropriate electronic circuitry.

Abstract: The dual-secondary mirror optical system utilizes, in principle, the Cassain optical system. An apertured, single, primary mirror is coaxially aligned with two secondary mirrors to provide coaxial transmit and receive optical paths. Separation of the optical paths is in radial distance from the central optical axis. An apertured secondary mirror in conjunction with the primary mirror directs the transmitted beam, providing a hollow expanded output beam. The other secondary mirror in conjunction with the primary mirror directs received radiation coaxially within and spatially separated from the hollow transmitted beam, providing dual transmit receive operation.

Abstract: The use of narcotic antagonists (e.g., naloxone) in shock therapy is disclosed.

Abstract: The therapeutic use of thyrotropin releasing hormone (TRH), its analogs aor metabolites in the treatment of circulatory shock and/or central nervous system (CNS) ischemic damage is disclosed. Additional evidence of the utility of TRH as a CNS stimulant is revealed.

Abstract: A bi-directional fibre-optic coupler providing about 70 dB to about 100 dB isolation from near end transmitter radiation in a system that transmits signals in opposite directions over a single fibre and thereby provides a low-loss coupler having operational characteristics to handle reception and transmission with sufficiently low value of crosstalk.

Abstract: A novel treatment has been discovered for interrupting the life cycle of malaria parasite during its development in the liver of the vertebrate host. The subject invention involves a method of chemotherapy against sporozoite-induced malaria by administering an 8-aminoquinoline drug, such as primaquine, encapsulated within liposomes containing glycoconjugates, to a vertebrate host which has been infected with sporozoites of the parasites. Preferred species of glycoconjugates have a terminal glucose or galactose moiety, such as present in glycosyl ceramide, galactosyl ceramide, lactosyl ceramide, or in glycoproteins.

Abstract: The silver salt of metachloridine has been shown to have marked effectives against viruses, bacteria, fungi and protozoa. It is active against the organisms over a considerable concentration range in vitro, and has a noteworthy, high chemotherapeutic index when administered to animals by topical, oral or parenteral route. In addition to its effectiveness, silver metachloridine has been shown to be well tolerated at levels far above those required for therapeutic uses in animals.

Abstract: A normally open laminated electrical switch comprises a sandwich of two electrically conductive sheets on opposite sides of, and separated by, a thin layer of insulation. Upon rupture or discontinuity of the thin insulative layer, the electrically conductive sheets are adapted to contact each other and to close the switch.

Abstract: Disclosed is a method for increasing the burning rate of solid propellants hich contain metal staples and/or metal flakes, etc., through the use of an electrical field effect created by the application of direct-current to a propellant grain placed between direct-current electrodes. This method also provides a means of correcting for anisotropy of burning rate in propellants which contain metal staples, metal flakes, etc., where non-random orientation may occur at the motor wall and mandrel surface.

Abstract: A teleconference system for N conferees, N being greater than two, includes at least two separate stations. Each station has N conferee positions, confronting a virtual conference space, and corresponding conferee positions at each station have the same relative locations about the virtual conference space. At least one conferee position at each station is adapted to be occupied by a conferee in person. Surrogate conferees, which include a video display, a video camera, and a loudspeaker, occupy each conferee position not adapted to be occupied by a conferee in person. Each video display faces one conferee and displays the image of another conferee at a corresponding position at another station; the loudspeaker reproduces the voice of the other conferee. The video camera forms image signals of the one conferee and couples these signals to the display device of a surrogate conferee at a conferee position corresponding to the position of the one conferee at the other station.

Abstract: Water soluble hydrogels of alkali metal alginate and glycerine have been found to be excellent wound dressings. The gels dry to an adherent, non-toxic pliable protective film which can be removed by water-washing when desired. The gels are also compatible with medicaments and hence can serve as vehicles or carriers for medicament application to wounds as well as a protective cover.

In the preferred spectacle, the frame has a biconcave recessed bridge and the temple yokes are apertured to detachably mount on said rim means by snapping over temple pivot posts projecting upwardly and downwardly on said frame rim.

Abstract: Water soluble hydrogels of alkali metal alginate and glycerin containing 0.01 to 1% cupric (copper) sulfate pentahydrate or silver salts such as silver acetate, silver lactate monohydrate and silver nitrate have been found to be excellent wound dressing treatment composition for white phosphorus burns.Cupric sulfate pentahydrate or silver salts such as silver acetate, silver lactate monohydrate and silver nitrate in the gel reacts with the particles of white phosphorus to form a coating around said particles thus rendering them unable to cause further burn injury to the skin. The gels dry to an adherent, non-toxic pliable protective film which can be removed by water-washing when desired. The gels are also compatible with other medicaments and hence can serve as vehicles or carriers for medicament application to wounds as well as a protective cover.
