Abstract: A process for producing 3',5'-cyclic adenylic acid in a high yield at a lower price by culturing a strain belonging to the genus selected from the group consisting of Corynebacterium, Arthrobacter and Microbacterium such as, for example, Corynebacterium murisepticum No. 7-10 (ATCC 21977), Arthrobacter 11-211 (ATCC 21978) Microbacterium No. 205-CM7 (ATCC 21979), Microbacterium No. 205-CM-XA3 (ATCC 21980), or Microbacterium No. 205-MP-197 (ATCC 21976) in a medium containing nutrient sources such as, carbon sources, nitrogen sources, inorganic salts and the like but containing no precursors and having a pH of 5-9 at a temperature of 20.degree.-40.degree. C under aerobic condition. The obtained 3',5'-cyclic adenylic acid is well-known for its participation in various biochemical reactions in vivo and for its active role as a mediator to various hormones. It has therefore always been highly evaluated biochemical reagent.

Abstract: A bread containing substantial quantities of alfalfa provides a convenient, palatable form of introducing significant quantities of alfalfa into the human diet. The bread, which preferably contains honey, retains bread-like texture, taste and odor despite the presence of substantial quantities of alfalfa. Alfalfa, a nonnutritive fiber, functions as a hypocholesteremic agent.

Abstract: An automatic text processing system, wherein a text is printed by a typewriter and simultaneously recorded line by line in corresponding blocks of a magnetic tape. The system automatically prints the address of the block in which each line is stored, whereby an operator can cause the system to print selected lines of the text by posting the corresponding address on the typewriter. The lines or paragraphs of a text can be cancelled or added and their succession can be changed, by posting the addresses of the lines which are to be cancelled, added or shifted in the text. The fair copy is then automatically printed with the lines justified according to a format selected by the operator. According to another embodiment the system can be used to automatically search the information recorded on the magnetic tape.

Abstract: A multiple control unit for selectively connecting a plurality of peripheral units to a central processor comprising a register for storing the interruptions coming from the peripherals; a disabling circuit for disabling the cell storing the interruption executed by the central processor in response to an end-of processing signal generated from the CPU.

Abstract: In a computer for executing a program made up of a plurality of instructions stored in an operational memory, in which the system is controlled by a set of microprograms stored in a read-only memory, the program instructions to be executed are transferred one at a time to a scratch pad memory, where they are used to address corresponding microprograms in the read-only memory. The microinstructions of the addressed microprogram are transferred one at a time to a microinstruction register, where each one is used to control the generation of a plurality of sets of commands to various components of the machine for executing the program instruction. The control unit includes means for transmitting control signals and data to the peripheral units with the data being already decoded into a form in which it is able to directly control the data output mechanism of the peripheral unit, without further modifications by a peripheral unit control unit.

Abstract: A gas distributor tube formed from a non-porous ceramic material having a generally axial passageway at least part of which is in the form of a helix. A treatment chamber or reactor is provided with a number of distributor tubes located in the base of the chamber to permit the introduction of a gas through the passageway of this distributor into the treatment chamber in which a solid material in finely divided form may be maintained in fluid suspension.

Abstract: The manufacture of cement clinker in a rotary vessel wherein cement raw materials are heated to complete calcination and effect clinkering by the combustion of fuels in the gaseous atmosphere within the vessel is improved by incorporating into the cement raw materials a residual fuel having a low volatiles content and a high ignition temperature.

Abstract: A device is presented which prevents rain drops from penetrating and which allows light and gas to be transmitted in a rain-free environment.

Abstract: A biprogrammable computer is provided with an operator actuable selector switch. Each position of the selector switch of the computer assigns the keyboard, the console and the display to a selected one of the two programs in progress, so that the data entered by the keyboard is automatically transferred to the memory zone allocated to the program selected at the same time the display displays messages of the selected program. If the program not selected by the selector switch must alert the operator to some abnormalities, it activates a lamp and an associated buzzer. The operator after the end of the keyboard operation, actuates the selector switch and removes the cause of the abnormality. Registers are provided for storing the point of interruption of a program being processed, as well as information for determining if the data being entered by the keyboard relates to the program selected.

Abstract: An ultraviolet-transmitting glass window assembly comprising a metallic mounting ring containing an ultraviolet-transmitting glass is made by placing a preformed ultraviolet-transmitting glass member in the center of the metallic ring which has a higher coefficient of thermal expansion than the glass, heating the resulting assembly to melt the glass whereby it completely fills the ring, and cooling the assembly whereby a compression seal is achieved due to the greater shrinkage of the metallic ring. This window assembly is sealed over the memory chip of a programmable read only memory package to provide for ultraviolet erasure of the program information stored in the memory device.
