Abstract: A method and media for producing bacterial cellulose under agitated culture conditions resulting in sustained production over an average of 70 hours of at least 0.1 g/liter per hour are achieved. A unique reticulated cellulose product is produced using the methods and conditions claimed, and may be converted to of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production.

Abstract: An EHF array antenna backplate that integrates thermal cooling structure and signal processing structure together into one unified structure. In one embodiment, forced air is employed to conduct heat from active modules; while in another embodiment, embedded heat pipes are employed. The array backplate is made by using four layers. The layers are: a high density multichip interconnect board, a metal matrix composite motherboard, an integrated waveguide/cavity/cooling structure, and a metal matrix composite baseplate. Each module uses solder bumps to connect to the high density multichip interconnect board where DC power and control logic signal distribution takes place. The modules are soldered in four locations to the metal matrix composite motherboard through openings in the high density multichip interconnect board. EHF signals are coupled to the modules from a resonant cavity via probes that protrude through the high density multichip interconnect board.

Abstract: Method for encapsulating biologically active material within a semipermeable capsule wherein gelled beads are obtained by suspending the material in a solution of a water-soluble substance which can be reversibly gelled, forming the solution into droplets and gelling the droplets to produce discrete shaped-retaining temporary gelled beads.

Abstract: A waveguide hybrid includes a generally rectangular superstructure defined by first and second conductive broad walls and first and second conductive narrow walls, and an intermediate, conductive narrow wall bifurcating the superstructure into first and second generally rectangular waveguides, with each of the waveguides being provided with a central, longitudinally extending land or ridge, preferably having a generally rectangular, cross-sectional profile. A coupling window is provided in a central portion of the intermediate narrow wall, which is shared in common by the first and second waveguides. Further, a capacitive button, which preferably takes the form of a square peg, is provided on the floor of the superstructure between the lateral surfaces of the common narrow wall which define the coupling window. In operation, RF energy, such as a microwave excitation signal, is injected into the input port of the first or primary waveguide, thereby launching a TE.sub.

Abstract: A filled pastry roll is made from a continuously supplied strip of pastry by apparatus in which a conveyor conveys the pastry through a sequence of treatment stations. A receiving station includes a cutter which cuts a square of pastry from the leading end of the strip. A feeding station includes means for feeding a filling onto the square. A first folding station includes a movable deflector which folds one corner of the square over the filling. A second folding station includes a pair of opposed deflectors which fold the two adjacent corners inwards in succession, so that they overlap. A rolling station includes two parallel platforms between which the folded pastry is rolled by relative reciprocation of the platforms.

Abstract: Apparatus providing a controlled environment for intensive cultivation of vegetable matter, e.g. bean sprouts is disclosed. A valve regulates the supply of water from a reservoir to a water-spray inlet in the roof of a cultivation chamber having an air vent and a water drainage outlet. A timing device, operatively connected to a valve actuating mechanism, opens the valve for a predetermined length of time at predetermined intervals. The water supplied to the spray inlet is heated by a thermostatically controlled heater. The chamber may be thermally insulated and its interior may be heated by a thermostatically controlled heater.
