Abstract: ABSTRACT OF DISCLOSURE Vinegar having an acetic acid content of 18-20% is produced by aerobic bacterial oxidation of ethanol in a combination of semi-continuous fermentation and batch fermentation.  The semi-continuous fermentation provides 10-12% vinegar, a portion of which is then converted to 18-20% vinegar in a batch fermentor operating at a temperature substantially lower than that employed in the semi-continuous fermentation. Gas is admixed with the fermentation mixture prior to its being subjected to microfiltration or ultrafiltration during its transfer from the semi-continuous fermentor to the batch fermentor.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for deep hole rock drilling in which the drilling shaft is made up of extension pieces joined together by a thread system.  A central flushing channel is made in the extension pieces through which water or air is conveyed to the hole and with the aid of which the drilled material particles are carried out of the hole through the side flushing channel between the drill shaft and the wall of the drilled hole.  In accordance with the invention the cross-sectional surface area of the drill shaft corresponding to the diameter of the hole to be drilled is selected in accord-ance with the power of the drilling machine to be used and thereafter the outside diameter and central flushing channel diameter of the tubular drill shaft are selected so that the cross-sectional surface area of the central flushing chamber is essentially equally large as the cross-sectional surface area of the side flushing channel.  The drill shaft is tubular and is manufactured of steel tube such that the relationship of the inner diameter to the outer diameter is in the range 0.7..Ø9.  The thread helix angle and form height of the threads of the screwed components of the tubular extension pieces are constants independent of the outside diameter of the tube, so that the threads pitch and number of thread starts increases with the increase in outside diameter of the tube.

Abstract: SO-2-33349M/AO/83.     ABSTRACT OF THE DISCLOSURE  A device for detecting fracture faults in optical power transmission fibers in which a plastic fiber is laid parallel  to  and  closely  adjacent  the  power transmission fiber.   The plastic fiber has a melting point lower than a temperature reached by a portion of the power transmission fiber containing a fracture fault when power is applied to the power transmission fiber.   The portion of the plastic fiber  adjacent  the  fault  melts,  thereby  interrupting  the path of a reference beam through the plastic fiber from a reference  beam  source  to  a detector.   The  absence  of  a returned  reference  beam  at  a  detector  is  taken  as  an indication that the power transmission fiber has a fracture fault.

Abstract: STRETCH FILM WRAPPING DEVICE            ABSTRACT OF THE INVENTION    A stretch film wrapping device for rotatably supporting a roll of plastic film having a tubular rigid central core includes a pair of opposed core holders interconnected by a length adjustable axle member to effect clamping of the film roll between the core holders.  The bottom core holder is mounted on a base member.  The top core holder is rotatably mounted on the axle member and is axially shiftable upwardly thereon.  The top tension control assembly above the top core holder at the top of the axle member adjusts the clamping force on the film roll and includes a spring which engages the top core holder to resist upward axial shifting of the top core holder when the axle member is adjusted to reduce the distance between the core holder to effect clamping of the film roll between the core holders.  The clamping force between the core holders on the film roll varies in direct proportion to the force of the spring in resisting upward axial movement of the top core holder with respect to the axle resulting in precise adjustment of the film tension for the wrapping operation.

Abstract: ABSTRACT OF THE DISCLOSURE            A masking circuit for a multiprocessor system is disclosed.  In the multiprocessor system, a first command status register contains information associated with a first processor of the multiprocessor system and a second command status register contains information associated with a second processor of the multiprocessor system. Normally, the command status registers contain command information related to the processing of commands for their respective processors.  However, during a flush operation, wherein data stored in the cache of a second processor is flushed to a main memory in order to allow access to the data by a first processor, the command being executed by the first processor must be blocked in order to allow the flush operation to be completed.  When the flush operation is complete, the execution of the command by the first processor commences.  The first command status register contains the command being executed by the first processor, and the second command status register contains information related to the need for a flush operation.  The masking circuit of the present invention senses the existence of the command in the first command status register and the information, related to the flush operation, in the second command status register and masks the command in the first command status register from the multiprocessor system until the flush operation (as indicated by the contents of the second command status register) is complete.  When the command is masked, the execution of the command is postponed until the flush operation is completed.  When the flush operation is complete, the second command status register is reset.  When reset, the multiprocessor system is permitted to commence execution of the command.
