Abstract: ABSTRACT OF THE DISCLOSURE   In a data processing system having a plurality of virtual address spaces, a virtual address is translated into a real address for accessing a main memory and the translation result is stored in a translation look aside buffer, as in a processing system having a single virtual address space. Thereafter, in the case of the same virtual address as the above, the trans-lation look aside buffer is retrieved to translate the virtual address into a real address.  Generally, even in the case of the same virtual addresses, if their virtual address spaces are different, the virtual addresses are translated into different real addresses.  However, a control program, a control table or a common subroutine is provided in a common area in which the coordination of virtual and real addresses is always constant even in the case of different virtual address spaces.  To enhance the efficiency of utilization of the translation look aside buffer, common area indicating means is provided, by which the coordination of virtual and real addresses on the translation look aside buffer is registered so that it can be used in common to a plurality of virtual address spaces.

Abstract: ABSTRACT           This disclosure is directed to an air cleaner for use with internal combustion engines that cleans the air by separating particulate matter prior to filtration.  The air cleaner consists of a cylindrical casing having an axial inlet for uncleaned air, a first outlet for the separated particulate matter and a second outlet for the cleaned air.  A separator taking the form of a truncated cone converges from the inlet to the first outlet, and includes a plurality of louvers that define a flow path to the filter and clean air outlet.  By reason of its inertia, particulate matter in the incoming uncleaned air is incapable of changing its direction to flow through the louvers, and it continues toward the first outlet for discharge.  The filter is also conically shaped and con-centric with the separator, formed from inner and outer perforate shells with a pleated filter sandwiched therebetween. The separator and filter are preferably formed as a single unit that is replaceable through removal of an end cap of a casing.           The apparatus may also include a high pressure nozzle to assist in removal of the separated particulate matter from the unit.

Inventor: CLEMENT PHILIPPE
IPC: C12N1/18
Filed: 1977-12-23
Granted: 1981-07-21
Abstract: ABSTRACT OF THE DISCLOSURE      A complete and reproducible process for producing novel strains of yeast, comprises making a first screening test and at least one other screening test selected from a group of screening tests which do not resort to any measure-ment of gas release, selecting by means of said first and at least one other said screening test the desired strains from a group of diploid strains prepared previously either by hybridation, or by mutation of existing strains.  The tests are as follows:  A first test consists of measuring the average multiplication coefficient of a given strain by following the optical density variation of a standard medium seeded by a suspension of cells obtained from this strain.  A second test consists of measuring in the same manner the average multiplication coefficient of the said strain in the presence of an inhibitor acid added to the standard medium.  A third test consists of measuring the maltose adaptation of said strain in the presence of glucose by determining the amount of maltose subsisting in a standard medium after a known amount of glucose added to this medium has been completely consumed.  A fourth test consists of measuring the invertase content of said strain.  A fifth test consists of measuring the latent time of said strain.  The hybridation can consist of systematic haploid crossings derived from quick Saccharomyces Cerevisiae strains adapted to maltose and haploids derived from very slow strains not adapted to maltose, but well adapted to sweet doughs and sometimes also to acid doughs.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an off-base fed tunable, low profile blastproof and broadband whip antenna and coupler system for advanced generations of vehicular military communication sets operating over 30 to 88 mega-hertz (MHz) frequency band.  For a direct replaceability with marrower bank systems (30-76 MHz) of prior art, the 30-88 MHz band is sub-divided into ten (10) sub-bands.          The whip antenna is according y series tuned at each sub-band by suitably designed fix-tuned circuits within the antenna coupler unit integrated into the base of the antenna assembly.  The ten (10) tuning circuits are arranged around a selector embodiment in the form of a stack of two multiprongs circular wafers, the center parts of which are free to rotate by an axle actuated by a Solenoid step-rotor or manually to connect appropriately tuned circuits for efficient operation in respective frequency sub-bands.  The step switching of the rotary selector may be remotely controlled to connect/disconnect to the fix-tuned circuits in accordance with desired frequency sub-bands within the 30-88 Mhz band.  The antenna system that has evolved in relation to the present invention is uniquely designed to be inconspicuous - no tie-down is necessary; rugged - may survive the harshest military environment; easy to maintain - modular-type construction; ground insensitive - base choked by means of a helical re-entrant cavity resonator; able to accom-modate broad frequency spectrum of most advanced VHF military transceivers.
