Abstract: A rechargeable power pack (31) is shaped and dimensioned to be inserted in the battery compartment of an electrical device. The top (32) of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack has a peripheral wall (36) spaced apart from the sides of the battery compartment mounting the battery contact terminals. Flexible prongs (45, 46) project from the peripheral walls (36) to provide a wiping contact with either a spiral spring negative terminal or a stationary positive terminal. A top mounted connector (52) allows recharging of the power pack either during or after operation of the electrical device. An alternate embodiment combines a set of NiCad rechargeable batteries and a cover assembly including an additonal battery station to compensate for lower rated voltage of NiCad power cells, a recharging connector and associated current limiting circuit, and a flexible conductor with terminals specially adapted for insertion between the battery poles and the corresponding terminals. <IMAGE>

Abstract: Functional antibody fragments can be produced in bacteria by coupling each of the genes for the individual chains to signal sequences which bring about the transport of the prepeptides through the cytoplasmic membrane, expressing the gene structures in a bacterium, and isolating the functional protein from the periplasmic space or the medium. The functional protein is advantageously isolated by affinity chromatography on an adsorbent which is loaded with the hapten or antigen, and elution with a solution of the hapten or antigen.

Abstract: Immunostimulant products are prepared by adding lysozyme to a culture of L.bulgaricus at a pH of from 4-8 and then incubating the culture to hydrolyze peptidoglycans of cell walls of the bacteria. A suspension containing the lysozyme-treated L.bulgaricus is collected, which is centrifuged to obtain an immunostimulant supernatant. The supernatant may be filtered to obtain an immunostimulant solution, which may be added to a fermented milk, or to a whey, to prepare an immunostimulant product. Alternatively, L.bulgaricus may be cultured and hydrolyzed by lysozyme in a milk product to provide an immunostimulant milk product.

Abstract: A low profile composite material bedding foundation system and methods of manufacture and assembly uses spring modules made of molded composite materials and supported by inner frame members. The low-profile of the spring modules, and the composite material spring property of return to uncompressed state from total depth deflection without set, greatly decreases the height of the bedding foundation in which the spring modules are attached directly to foundation frame members. The small size and simple geometry of the spring modules is especially suited for flexible arrangement and automated assembly of low-profile foundations.

Abstract: Peptidyl-glycine  alpha -amidating monooxygenase is an enzyme extractable from medullary thyroid carcinoma cell lines and tissue samples, having a molecular mass of about 60,000 to 65,000 daltons. It has been purified so as to exhibit a single, homogeneous, well-defined band using electrophoretic procedures performed on SDS-polyacrylamide gels, and has a specific enzymatic activity of at least 50 mU per mg protein. The free or immobilized enzyme, in the presence of Cu+2 ions, ascorbate, and oxygen, can be used to prepare an  alpha -amidated protein from a polypeptide substrate possessing a carboxyl-terminal glycine residue. The purified enzyme can be used as an antigen in order to produce enzyme-specific monoclonal antibodies, and can provide the information necessary to design and construct prokaryotes or other appropriate unicellular organisms or host cells isolated from multicellular organisms which possess peptidyl-glycine alpha -amidating capability.

Abstract: In the coding and decoding of stereo audio spectral values both the intensity stereo process and prediction are used in order to achieve high data compression. If intensity stereo coding is active in one section of scale factor bands, the prediction for the right channel in that range is deactivated, whereby the results of the prediction are not used to form the coded stereo audio spectral values. To allow further adaptation of the prediction for the right channel, the predictor of the right channel is fed with stereo audio spectral values for the channel, which again are intensity stereo decoded.

Abstract: Multilayer printed circuit boards are fabricated by preparing a first layer in conventional manner by forming a resist image on a copper clad substrate, etching away unwanted copper, removing the resist from the circuit pattern and optionally applying a dielectric mask such as conventional solder mask to selected portions of the circuit pattern. A second layer, and optionally one or more subsequent layers, are fabricated by providing an image of a second circuit pattern in a predetermined location on said first layer, the image being formed using a suspension of cuprous oxide in a curable resin material. The image is cured at least partially and subjected to chemical reduction to convert at least a portion of the cuprous oxide to metallic copper such that the unreduced cuprous oxide in resin serves as a dielectric layer. The image is then electrolessly plated with copper to build up the circuit pattern and the latter is selectively coated with a dielectric mask before repeating the cycle to build up one or more additional layers. Solder can be applied to selected areas of any of said printed circuit layers at any appropriate time during fabrication. The above method of fabrication has advantages of economy of time, materials and labor as compared with methods hitherto employed to prepare multilayer boards in which a plurality of single boards are fabricated individually and then assembled as a sandwich or laminate by application of heat and pressure.

Abstract: The present invention provides an improved method and apparatus for growing biomass particles, particularly microcarrier-bound cells, in an agitated suspension culture vessel in which fresh culture medium is added and spent culture medium is withdrawn continuously or semi-continuously. The improvement comprises withdrawing the spent culture medium through a particle settling chamber located within the vessel and at least partially immersed in the agitated culture medium therewithin. The particle settling chamber comprises a hollow container with a bottom opening through which biomass particles, such as microcarrier-bound cells, settle by gravity back into the agitated culture medium and a top opening through which particle-free spent culture medium is withdrawn form the vessel. The settling chamber is configured such that the fluid velocity of culture medium entering the settling chamber through the bottom opening is significantly less than the biomass particle settling velocity.

Abstract: The invention relates to a device for producing active oxygen ions in the air for improved air quality, comprising at least one air ionizer and an electric transformer producing sufficient electrical high voltage for air ionization. The air ionizer is coupled to a sensor which detects the oxidizable gas content in the air (air pollution sensor). On the basis of the detected content of such oxidizable gases, the electrical energy which is guided to the air ionizer is transformed by an electrical control device in such a way that only low-level ionization occurs at low concentration of oxidizable gases. Said ionization is sensor-controlled and can automatically be increased to a maximum value when the concentration of oxidizable gases rises.
