Patent CA-2099025-A1 (CA)
Inventor: CHIN ARTHUR L
IPC: G06F13/36
Filed: 1993-06-23
Abstract: This  invention  relates  to  personal  computers,  and  more particularly to a personal computer using a FIFO registers for data transfer as illustrated by a bus master device in the  form  of  a  small  computer  systems  interface  (SCSI) controller for controlling data transfer with storage memory devices such as fixed or removable media electromagnetic storage devices.   In the practice of this invention,  the efficiency of a system having a plurality of bus master devices  is  enhanced  by  providing  for  a  programmable threshold  fill  condition  for  a  FIFO  register  before arbitration  for bus  control  occurs.   Thus  the  invention provides an approach to maximizing the efficiency of data transfer where FIFO registers are used.

Title: Computer automated bullet analysis apparatus
Inventor: BALDUR ROMAN
IPC: G06T7/00
Filed: 1992-05-22
Abstract: The apparatus analyzes and compares surfaces of fired bullets. A microscope obtains and amplifies optical signals representative of the characteristics of the surfaces, and the optical signals are converted, first to electrical signals and then to electrical coded digital representations. The coded digital representations are stored in an electronic memory. The coded digital representations of one bullet can then be computer compared to the coded digital representations of another bullet to determine if there is a match between the bullets.

Patent CA-2114959-A1 (CA)
Inventor: BEACH JOHN R
IPC: E04D15/00
Filed: 1990-01-26
Abstract: A machine for fastening one or more layers of roofing material to an underlayment, and a stackable washer therefor.  A chute receives a stack of such washers.  A shuttle displaces a single washer to a separated position when moved in one direction, to which the shuttle is biased, releases the single washer when moved oppositely.  A gate, which cooperates with camming surfaces on the respective washers, restrains the overlying washer in th stack against being displaced with the single washer and restrains the single washer from being displaced from the separated position.  Various components are provided by linking a stand-up screw gun of a known type to the shuttle.  The stackable washer is embossed so that each such washer and like overlying and underlying washers in a stack contact each other at three or more places, which define tangent planes intersecting planes defined by planar areas on such washers at angles more thant 45° but less than 90° whereby such washers are spaced from each other around their entire peripheries.  Notches in the washers cooperate with ribs in the chute to ensure that a stack of the washers is oriented properly when fitted into the chute.

Patent CA-2122134-A1 (CA)
Inventor: OWEN HARTLEY
IPC: B01J38/38
Filed: 1991-10-30
Abstract: In a process for controlled, multi-stage regeneration of FCC catalyst, a modified high efficiency catalyst regenerator (80), with a fast fluidized bed coke combustor (62), dilute phase transport riser (83), and second fluidized bed (82) regenerates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor (62), whereas a second stage catalyst regeneration occurs in the second fluidized bed (82). The amount of combustion air added to, and conditions in, the coke combustor (62) are controlled to limit CO combustion, while the second stage of regeneration, in the second fluidized bed (82), achieves complete CO combustion. Controlled multi-stage regeneration reduces steaming or deactivation of a catalyst during regeneration, increase coke burning capacity, and reduces NOx emissions.

Title: Mobile machine for processing raw mineral ores in-situ
Inventor: SCHADE JORG
IPC: B07B13/16
Filed: 1994-07-13
Abstract: ABSTRACT           MOBILE MACHINE FOR PROCESSING RAW MINERAL ORES IN-SITU        A mobile machine for use  in opencast mining employs a chassis with endless tracks and the chassis has outriggers projecting  laterally outwardly  from the tracks.    A hopper supported by one outrigger receives raw ore material excavated by another machine or machines.    The raw ore material passes from the hopper to a screen arrangement with superimposed oscillating screens which sieve the material to separate the finer mineral ore product from the coarser spoil.   The mineral ore product which passes through the screens  is transferred by a multi-stage  conveyor  extending perpendicularly to the tracks to a separate conveyor laid on the floor of the working alongside a path of movement of the machine.    The spoil is transferred with another conveyor to the inlet of a jib which extends laterally outwardly from the tracks opposite the hopper.  The jib itself has a conveyor which transports the spoil along the jib which then discharges the spoil onto a dump.

Patent CA-2139678-A1 (CA)
Title: Method and apparatus for processing a glass sheet
Inventor: FRANK ROBERT GEORGE
IPC: C03B27/044
Filed: 1995-01-06
Abstract: The present invention provides a glass sheet shaping arrangement whereby a glass sheet may be conveyed through a shaping station without being shaped and deposited into a glass collector beneath an upstream portion of the adjacent quench without impacting the lower quench or interfering with the operation of the quench. A furnace, shaping station and cooling station are all linearly aligned so that a glass sheet progresses through the glass sheet shaping arrangement without changing its advancing direction. A glass sheet is conveyed in a first direction along a first generally horizontal plane through the furnace to heat the sheet to its heat softening temperature. The sheet continues into the shaping station where it is lifted into engagement with an upper vacuum surface. A ring member moves along a second generally horizontal plane in a direction which is linearly aligned with the first direction, from a first position between an upper and lower quench in the cooling station to a second position within the shaping station beneath the upper vacuum surface. Vacuum is terminated along the upper surface, depositing the sheet on the ring. The shaped sheet is cooled by moving the ring from the second position within the shaping station along the second plane to the first position within the cooling station. The second plane is vertically offset relative to the first plane such that the first planeis beneath a portion of the lower quench which is immediately adjacent the shaping station. With this arrangement, the glass sheets may be conveyed through the shaping station and into the collector without interfering with any further production.
