Abstract: Animals, including humans, are immunized by antigens, for example, the HA antigen of influenza, by first administering to a naive animal a normally strongly-immunogenic form of the antigen, for example, inactivated or attenuated whole cell virus and subsequently administering a normally weakly-immunogenic isolated and purified viral antigen, to achieve an enhanced immune response to the purified viral antigen.

Abstract: A process for the subcritical drying of a lyogel to give an aerogel comprises treating the lyogel with a heat transfer liquid which has a temperature above the boiling point of the pore liquid of the lyogel under the pressure of the system and subsequently separating the dried aerogel from the heat transfer liquid.

Abstract: Devices for the duplication of industrial magnetic tapes. More particularly it relates to an electronic device for the fast duplication of magnetic tapes. The device, through a microprocessor, activates selecting circuits to control static memory cards of a memory bank. The selecting circuit generates proceeding signals and selecting signals which single out memory cells of the memory bank for writing and reading. These selecting signals and proceeding signals cause a subdivision of the cards in the memory bank, allotting a part of the memory for reading and another part for writing. The selecting and the proceeding signals are carried out through digital signals. The final digital signals are subjected to a digital-to-analog conversion.

Abstract: This invention relates to a low-pressure chromatography column 1 having a diameter of more than 30 cm, and essentially consisting of a vertical cylinder 13 having a base plate 12, a lower sintered disk 3 arranged above the base plate 12, an upper sintered disk 16 fastened to the underside of a lid designed as a mobile plunger 4, and having at least three controllable elements 5 for raising or lowering the plunger 4, which are connected to the plunger 4, equipped with sensors 6 electrically connected to a control unit 10 for determining the vertical position and horizontal placement of the plunger 4. With the aid of an optical observation device (e.g., endoscope), the plunger/gel material can be adjusted exactly over the entire positioning range of the plunger. The advantages of the invention include simple and rapid production of the packing and purer products than could be obtained without such packing.

Abstract: An adjustable spoon or scoop with a measuring container on each end. The spoon has a sliding cover with dams for adjusting the volumes in the measurement containers at both ends. The cover can be easily snapped off of the spoon body to separate the parts for easy washing. The dimensions of the containers at opposite ends of the spoon are set to cover different volume ranges; for example, 1/8 teaspoon to 1 teaspoon at one end, and 1 teaspoon to 1 tablespoon at the other end. Coordinated indicia are provided to indicate the measurements corresponding to each position of the slider. The dimensions of the measurement containers are determined so that a standard fractional measurement will be provided at both ends of the spoon by each of a plurality of sequential slider locations. The body has a slender central portion extending between the measurement containers.

Abstract: A region of the PspA protein of the Rx1 strain of Streptococus pneumoniae has been identified as containing protection-eliciting epitopes which are cross-reactive with PspAs of other S.pneumoniae strains. The region comprises the 68-amino acid sequence extending from amino acid residues 192 to 260 of the Rx1 PspA strain.

Abstract: The present invention relates to polymers with an extended system of conjugated double bonds constructed as homo and/or heterocyclic rings which are interlinked in pairs so that one ring is joined to the neighboring one at two adjacent atoms in the ring, in which one of these connections is made by a chemical bond to a ring atom of the neighboring ring and the other via a carbon, nitrogen, oxygen or sulphur atom to an atom of the neighboring ring adjacent said ring atom, their production and use in electrical, electronic and opto-electronic components.

Abstract: The invention relates to solid active substance formulations which contain wetting agents in combination with a surfactant (antifoam) from the group comprising perfluoroalkylphosphinic acid/perfluoroalkylphosphonic acids or their salts. The invention also relates to the use of these formulations, in particular in the preparation of spray slurries.

Abstract: Fiber-optic cable is wound on a cylindrical bobbin without adhesive and is situated in the vehicle so that the cable, attached to a relatively stationary control computer station, is pulled freely off of the bobbin as the vehicle, such as a missile or torpedo, travels rapidly away from the station. In one embodiment, a propulsion engine is located within the hollow interior of the bobbin and the cable flows outwardly in a helix around the plume of the engine.

Abstract: A system for remotely starting a motor of a vehicle and also capable of operating various vehicle accessories such as alarm system, door locks, door windows, trunk latch, etc. The system comprises a portable hand-held transmitter generating a command in the form of a binary coded sequence and a controller mounted in the vehicle for operating the vehicle's motor and accessories in dependence thereon. The system is characterized by a novel encoding scheme of the digitized sequence that prevents command misinterpretation by the controller, thereby avoiding an unintended avocation of the vehicle's motor or another accessory.

Abstract: A system and method for tracking compact discs during manufacture comprising a spindle having a central shaft and a base for carrying a plurality of compact discs, electronic memory storage system connected to the spindle, and data transfer means cooperating with the spindle to send and receive information identifying compact discs carried by the spindle and/or providing processing information about compact discs carried by the spindle from or to the electronic memory storage system.

Abstract: Apparatus for reducing acoustic background noise for use with a telephone handset or a boom microphone device or a boom headset or the like. The apparatus includes first and second microphones which are arranged such that the first microphone receives a desired speech input and the background noise present in the vicinity of the speech, and the second microphone receives substantially only the background noise. The background noise from the second microphone is converted into a corresponding electrical signal and subtracted from a signal corresponding to the speech and background noise obtained from the first microphone so as to produce a signal representing substantially the speech.

Abstract: A rotary disk storage system is provided for use with portable or laptop computers which is designed to achieve an overall maximum height ("Z-height") not greater than 17 mm. In attaining this result, the top cover and lower base plate of the housing of this rotary disk storage system are sealed by a pressure sensitive adhesive which permits the top cover to "float" on the lower base plate. Moreover, the reduced overall height is attained by forming the spin motor which rotates the magnetic disks integrally with the lower base plate. Further, IC chips are mounted on the printed circuit board to provide signal processing to a host computer, these IC chips being mounted on one side of the printed circuit board to face the lower base plate of the disk storage system. When the rotary disk storage system of the present invention is assembled, each of these IC chips is accommodated within differentially-sized pockets formed in the bottom surface of the lower base plate.
