Patent CA-2012481-A1 (CA)
Title: Interlace printing process
Inventor: DOAN ALPHA N
IPC: H04N1/52
Filed: 1990-03-19
Abstract: ABSTRACT OF THE DISCLOSURE      Quality of printed images as produced by an ink-jet printer (10) is improved by staggering applications of ink dots (30) to pixel locations (36) such that overlapping ink dots are printed on successive passes of a printhead (16) and such that swaths (38) are partially printed on overlap-ping passes of the printhead.  Quality of multi-colored or multi-shaded images is further improved by grouping pixels (36) into super pixels (42), and applying various combina-tions of colored ink dots to the various pixels within each super pixel in a staggered sequence.
Patent CA-2012972-A1 (CA)
Inventor: BELAND ROBERT
IPC: G01T1/24
Filed: 1990-03-23
Abstract: A plurality of phototransistors are connected in a matrix of rows and columns. Light falling on the phototransistors discharges the interelectrode capacitance between the emitter and collector of each phototransistor.      Each phototransistor is permitted to discharge for a given period of time. A current source then charges the interelectrode capacitance back to its original level. The amount of time taken to recharge the interelectrode capacitance is a function of the intensity of the light falling on that phototransistor.

Patent CA-2024109-A1 (CA)
Inventor: LETWIN JAMES G
IPC: G06F12/08
Filed: 1990-08-28
Abstract: The invention is a method and system for opti-mizing data transfer from non-volatile memory (e.g. floppy or hard disk) into random-access memory.  Upon opening a file, an access log is created.  File access behaviour for the file is monitored and recorded in the file access log. A determination is made whether the file access behaviour was sequential,  or sequential and fast.  If the access behaviour is determined to have been sequential and fast, then relatively large amounts of data are cached.  If the access behaviour was sequential but not fast then relative-ly small amounts of data are cached.  The access behaviour is recorded in an area associated with the file upon closing the file and may be read upon opening the file.

Title: Discharge lamp with surrounding shroud and method of making such lamp
Inventor: BIEL JOHN J
IPC: H01J9/32
Filed: 1991-05-09
Abstract: LD10,109 ABSTRACT          This discharge lamp includes (i) an inner envelope of vitreous material comprising a bulbous portion and two tubular portions extending from the bulbous portion and (ii)  a tubular shroud of vitreous material surrounding the bulbous portion and the two tubular portions.  The lamp is made by the following method.   A disk-shaped enlargement is formed in each of the tubular portions by heating a localized region of the tubular portion to its softening  point  and  then  subjecting  said  localized region  to  a  compressive  force  (i)  that  is  abruptly applied along the length of the tubular portion and (ii) that  drives  the  softened  vitreous  material  radially outward into a disk formation.  Then the tubular shroud is placed over the inner envelope so that each disk-shaped  enlargement  is  positioned  with  its  outer periphery closely adjacent the inner periphery of the surrounding  tubular  shroud.    Then  seals  are  formed between  the  outer  peripheries  of  the  disk-shaped enlargements  and  the  surrounding  shroud  portions  by heating each of the surrounding shroud portions to its softening  point  and  collapsing  it  about  the  outer periphery of the associated disk-shaped enlargement.

Patent CA-2055210-A1 (CA)
IPC: B65D41/34
Filed: 1991-11-08
Abstract: ABSTRACT A tamper resistant closure and a method of installing and removing that closure relative to a container where the container has a neck with external threads thereon and a ring located beneath the threads.  The closure has a central portion with a periphery and a skirt extending from the periphery, a tear strip extending from the skirt, a tamper evident band extending from the tear strip and a movable flange extending from the band.  The tear strip is affixed between the skirt and the band by a plurality of severable tabs.  The flange is hinged to the tamper evident band and is movable between an upper position and a lower position.  When the closure is installed on the container, the flange is forced against an interior of the band and overrides the ring.  Once the flange has overridden the ring, a free edge of the flange moves inward to rest against an outer surface of the neck beneath the ring.  The closure can then not be removed from the container without first severing the tabs as the flange will not override the ring during removal of the closure.  The tabs are severed by manually grasping a handle of the tear strip and removing the tear strip.  When the tear strip is removed, there is a relatively large gap between the skirt and the band, making it readily apparent that the contents of the container may have been tampered with.  Once the tear strip has been removed, the closure functions in a conventional manner for opening and closing the container.  With previous devices, the band is affixed to the skirt along a weakened line or through tabs without using a tear strip.  To remove the closure for the first time, the closure is manually turned until all of the tabs are severed virtually simultaneously. If the tabs are too strong, it can be extremely difficult to open the container.  If the tabs are too weak, some or all of the tabs become prematurely severed during the initial installation of the closure on the container or during shipping and handling.  With previous closures, it is very difficult to manufacture closures with tabs of the proper strength as the tolerances for error are extremely narrow. The tabs of the present invention can be relatively strong as they are severed singly or in pairs and not all at once.
