Title: Personal computer memory write control
Inventor: KEENER DON STEVEN
IPC: G06F3/06
Filed: 1992-04-14
Granted: 1998-02-17
Abstract: This  invention  relates  to  personal  computers,  and  more particularly to a personal computer using a small computer systems interface (SCSI) controller coupled directly to the local  processor  bus  for  controlling  data  transfer  with storage memory devices  such as  fixed or removable media electromagnetic storage devices.  The storage controller in accordance with this invention has internal volatile memory for transitory storage of data being communicated to coupled volatile memory.  It further has control drivers interposed between the internal volatile memory and external volatile memory for controlling communication of data to the external volatile  memory,  with   an  enable driver  and  an  enable receiver enchained between the control drivers and a source of signals controlling data communication.   The enchained driver and receiver are connected for issuing a write signal to the external volatile memory prior to enablement of data communication through the control drivers and for sustaining a control  signal communicated to the control drivers for enabling data communication until after deactivation of the write signal.

Title: System for measuring the distance between two stations mobile with regard to one another
Inventor: GUENA JEAN
IPC: G01S13/84
Filed: 1992-09-15
Granted: 1996-05-14
Abstract: An emitted wave is transmitted from a central station to a passive end. A phase modulation circuit in the passive  end modulates  a  signal resulting  from the emitted wave for retransmitting it in the form of a two-phase-state modulated signal at the rhythm of a clock signal.  In the central station,  the modulated signal is demodulated into two quadrature signals. On the basis of the product of the two quadrature signals and the sign of the difference between the moduli of the rectified quadrature signals, the count of an up-down counter  in  a  digital  processing  circuit  is incremented or decremented in order for said count to be  representative  of  the  distance  separating  the passive end and the central station.

Title: Dpcm predictive encoder
Inventor: KAWAYACHI NOBORU
IPC: G06T9/00
Filed: 1992-09-17
Granted: 1998-01-27
Abstract: In a DPCM predictive encoder for performing DPCM prediction by digitizing a NTSC color television signal with a rate three times of a color sub-carrier frequency, a two-frame predictor which outputs a differential signal over two frames is employed as one of predictors.   A predictor switcher adaptively selects one of prediction information as an optimal prediction signal and selects corresponding  differential  information  as  an  optimal differential signal. This differential signal is quantized by a quantizer.   The quantized output and the optimal prediction signal are summed by an adder and supplied to the predictors as a local decoding signal.
Patent CA-2083999-C (CA)
Title: Incorporation of a coprocessing additive into coal/oil agglomerates
Inventor: IKURA MICHIO
IPC: C10G1/00
Filed: 1992-11-27
Granted: 1995-11-28
Abstract: One method of coprocessing coal and heavy oil uses iron sulphate as a catalyst precursor which, upon decomposition to elemental iron and subsequent transformation to pyrite/pyrotite, assists hydrogenation of the slurry and suppresses coke formation.  For high process performance the iron sulphate should be dispersed as finely as possible throughout the reactant mixture.  In the present invention, the iron sulfate is added in the form of an aqueous wash solution to coal agglomerates after separation of ash from the agglomerated coal.  As the agglomerates remain in a continuous water phase, a good dispersion of the iron sulfate solution throughout the agglomerate matrix occurs.  At this stage an unexpectedly strong adsorption of FeII ions onto the coal surfaces occurs without any adverse effects on agglomerate integrity and the ability to separate it selectively by floatation.  Furthermore, this good dispersion also results in over 94% of the iron sulfate in the wash solution being transferred to the agglomerates. This manner of addition of iron sulphate to coal has been shown to elevate advantageously the lowest temperature at which coke formation occurs during coprocessing.

Abstract: A superconducting device comprises a substrate having a principal surface and a non-superconducting oxide layer having a similar crystal structure to that of the oxide superconductor, which has a projection at its center portion. A superconducting source region and a superconducting drain region formed of an .alpha.-axis oriented oxide superconductor thin film are positioned at the both sides of the projection of the non-superconducting oxide layer separated from each other and an extremely thin superconducting channel formed of a c-axis oriented oxide superconductor thin film is positioned on the projection of the non-superconducting oxide layer. The superconducting channel electrically connects the superconducting source region to the superconducting drain region, so that superconducting current can flow through the superconducting channel between the superconducting source region and the superconducting drain region. The superconducting device further includes a gate electrode through a gate insulator on the superconducting channel for controlling the superconducting current flowing through the superconducting channel. In the superconducting device the upper surfaces of the superconducting source region and the superconducting drain region have the same level as that of the superconducting channel.

Granted: 1996-06-25
Abstract: An apparatus for stretching tubular material with at least one closed end on a stretcher, in particular for stretching stockings, pantyhose, and the like on an elongated stretcher, is described, in which the tubular material is pulled onto the stretcher by means of belt drives. Each stretcher has at its lower end an end member at which there is provided a sensing device by means of which the belt drives are shut off as soon as the closed end of the tubular material arrives in the region of the end member. With the sensing device, the belt drives are reliably shut off regardless of the length of the tubular material being pulled on, which not only prevents slippage of the drive rollers of the belt drives, but also ensures complete pulling onto the stretcher.

Abstract: Les marqueurs génétiques de cette invention exercent une fonction de reporter biochimiquement dosable et présentent l'avantage de permettre une croissance pouvant être choisie en fonction des conditions. Les marqueurs comprennent un premier gène qui code pour un produit dont l'activité est biochimiquement dosable, par exemple la beta-glucuronidase, pour obtenir un deuxième gène qui confère un avantage de croissance en fonction des conditions, par exemple une résistance aux antibiotiques dans une cellule transformée (par exemple la néomycine phosphotransférase-II). Les gènes marqueurs et leurs produits de translation sont stables dans les cellules. Les marqueurs génétiques permettent une sélection génétique positive, ainsi que le triage biochimique et histochimique des cellules transformées. Ils peuvent être utilisés comme sondes pour identifier et isoler de nouveaux éléments de régulation génétique, par exemple des promoteurs, ainsi que les gènes qu'ils régulent.

Title: Adaptive control system input limiting
Inventor: LAMONTAGNE TROY J
IPC: B64C27/57
Filed: 1992-07-09
Granted: 2000-05-23
Abstract: A control system, having an input command signal and driving a prime mover, is provided with variable magnitude and/ or rate input signal limiting that is adjusted by maps (68, 70, 72, 74) which set the limits for a variable magnitude limiter (14) and a variable rate limiter (22) as a function of the prime mover rate. The limiting is adjusted dynamically as the prime mover rate changes. When the prime mover enters an undesirable operating condition, the maps only limit the command signal in the direction of such condition. The adjustable limiting is enabled or disabled based on the position, rate, and/or acceleration of the prime mover.
