Title: Protocol for read and write transfers
Inventor: THIRUMALAI AJAI
IPC: G06F11/00
Filed: 1990-07-30
Abstract: ABSTRACT OF THE DISCLOSURE    A process for transferring information including a source or destination address between two nodes in a network via data switching logic.  The switching logic must decode commands and addresses in order to adopt the proper configuration so that the command  and addresses can be forwarded from one system resource to another system resource.  A read or write address is transmitted to the switching logic and decoded in order to configure the switching logic.  The same read or write address is then retransmitted to the switching logic for forwarding to the appropriate system resource.  As a result, there is no need for extra storage logic in order to retain read and write addresses while the switching logic is being configured.

Title: Method for pixel - by - pixel absolute quantitation in computer assisted tomography
IPC: G06T7/60
Filed: 1990-11-26
Abstract: Abstract.  This  invention  develops  a  method  for  absolute quantitation in  computer  assisted  tomograph  systems.  This includes the definition of the dimension and the position of a tumour, as well as  the  evaluation  of  the  amount  of  drug delivered to a target volume and to surrounding tissues,  from the image.  The defined objectives can be achieved  using  the calibrated FWHM  (Full Width at Half Maximum)  values  of  the distribution of events versus distance in the tumour images to determine the dimension and the position of  the  tumour.  The activity  concentration   in   a   target   volume   and   the target - to - nontarget activity ratios can be  obtained  from the image using a new modified filter  in  the  reconstruction of the image and  the  calibration  of  the  system  for  this filter. The filter was tested on Positron Emission  Tomograph (PET)  images.    The  obtained  images   reflect  the   real distribution of activity used in a phantom. Using this filter, the colour scale of the image can  be  expressed  in  absolute units (µCi/ml) and the activity concentration can be evaluated in each pixel of the image or in each volume  element  of  the body.

Patent CA-2043772-A1 (CA)
IPC: H04N5/92
Filed: 1991-06-03
Abstract: In recording, a carrier is FM-modulated with a video signal to produce a FM carrier.  The phase of the FM carrier corresponding to a tip portion of a horizontal synchronizing pulse in the video signal (sync-tip carrier), is reset so that the phase is fixed at a reference phase at a leading edge of the horizontal synchronizing pulse during every period of the horizontal synchronizing pulse width.          The sync-tip carrier with its phase fixed is recorded in a magnetic recording medium.  In reproducing, the FM carrier picked up by the magnetic recording medium, with its frequency doubled by a doubler, is demodulated by a pulse count-type FM demodulator with a doubler function.  Then, a part of the FM carrier spectrum leaks into the FM demodulated video signal band, but the FM carrier is always in phase with the horizontal synchronizing pulse in the video signal, so that beat stripes or moiré do not appear on the reproduced picture, and the interference due to the leakage appears as reproduced picture distortion in correlation with the video signal.  Since the reproduced picture distortion is not likely to be detected by a human being as compared to asynchronously drifting beat stripes, the output of the doubler does not have to be passed through a high-pass filter to cut off a part of the lower sideband of the FM carrier.          The reference burst signal necessary to a time base corrector is extracted from the reproduced sync-tip carrier.

Title: Storage rack for cassettes and compact discs
Inventor: CHIZEN DWIGHT
IPC: G11B33/04
Filed: 1991-08-28
Abstract: A B S T R A C T     A storage and display rack for rectangular cases with flat sides and a thickness less than their height or width, such as audio or video tape cassettes or compact disc storage boxes.  The storage rack is a rigid perimeter frame consisting of two side rails, with a series of holes in a specific pattern,  into which are inserted pins.   The rails are connected by means which keep them in spaced parallel relationships such as a front and rear strut.  The distance between the side rails is slightly greater than the width of the case to be stored while the distance between the front and rear struts is only limited by the number of cases to be stored or the cabinet in which it is to be housed.  When inserted into the storage device, the cases are held at near their bottom between pairs  of  pins which allow the cases to stand in a substantially upright fashion either leaning forward or backward,  permitting the user to read the title imprinted on the face of a case as the ones in front are rotated  forward.   The  horizontal  spacing  of  the  holes on the  side  rails  determines  the  back  and  forward  angle  of inclination and repositioning of the pins permits container of  different  thickness  to be  stored and displayed in the same rack.  By permitting the cases of different thickness to be stored in the same rack and by permitting the user to reposition the pins to suit different sizes of cases, the rack  allows  for  greater  storage  flexibility than existing products.   The rack may be placed on any surface such as a counter top, table top, or shelf in a  cabinet.

Abstract: A method is provided for environmentally benign paint spraying with a dispersion of oven-curable lacquer in water in a paint spraying station having a cubicle with water-rinsed rear wall for collecting and washing out of overspray in cubicle waste water. The entire cubicle waste water is separated by ultrafiltration into permeate and lacquer-containing residue, the permeate being returned to the paint spraying station, the lacquer-containing residue being enriched with lacquer by removing water until its lacquer content is essentially equal to that of dispersion that is freshly fed to the spray painting station. The residue that is enriched with lacquer is admixed to the freshly fed dispersion for reuse in spray painting. A constituent for preventing coalescence of the lacquer is admixed to the dispersion fed to the paint spraying station, wherein a constituent for the inhibition of the drying is admixed to the dispersion that is fed to the paint spraying station, a constituent for adjusting the throughput for ultrafiltration is admixed to the cubicle waste water, and the conductibility of the water returned to the paint spraying station is monitored and kept below the limit.

Abstract: One of the mating connector housings has a locking arm and the other connector housing has an engagement sleeve that receives the locking arm.  The locking arm rises through a base at the front outer circumference of the first housing and extends axially rearwardly.  The locking arm has guide means formed at the base.  The engagement sleeve has engagement groove means formed in side walls thereof that extend axially from the front opening toward the rear and which receives the guide means.  When the paired connector housings are connected together, the guide means of the locking arm are received into the engagement groove means in the engagement sleeve to prevent the weak portion of the connector housing formed with the locking arm from being deformed, thus providing a good locking feel and also an adequate engagement stroke.  This makes the complete connection of the connector housings easily verifiable.
