IPC: B60P3/14
Filed: 1995-10-27
Abstract: A  work  platform  assembly  and  trailer  system  for transporting and vertically positioning the work platform assembly adjacent bridge deck surfaces to be treated.   The trailer  includes  front  and  rear  lifting  assemblies  for supporting, and being removably attached to, an end of the work platform  assembly.   The  lifting  assemblies  include vertically  oriented  lifting  cylinders   for  vertically positioning the work platform assembly immediately adjacent the bridge deck surfaces to be treated.  The trailer includes wheels and a hitch to facilitate the transport of the work platform assembly to the site of the bridge deck.  The work platform assembly is modular in construction so as to be configurable  according  to  the  configuration  and  size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating.   An adjustable curtain frame and/or other devices enable sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment.  Airborne residue is evacuated by vacuum into a dust collection system for subsequent disposal in a manner which does not contaminate the environment,  while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly into a residue separation system for subsequent, environmentally safe separation and reconstitution of the grit for reuse.   The dust collection and residue separation systems may be removably attached to the trailer.

Patent CA-2171159-A1 (CA)
Title: Compact photosensor circuit having automatic intensity range control
Inventor: STANDLEY DAVID L
IPC: H03F3/08
Filed: 1996-03-06
Abstract: A compact photosensor circuit provides automatic intensity range control for machine vision systems. The circuit may be implemented with standard CMOS integrated circuit technology to provide high sensitivity, fully static operation, and automatic exposure control with no moving parts. For each pixel of an imaging array, a photodetector provides an input photocurrent to a corresponding photosensor circuit. The photodetector is connected to provide an output voltage and an input to the gates of a pair of series-connected FETs that act as an attenuator. The attenuator is connected to a biasing source that provides a floor bias voltage. An output of the attenuator is connected to the gate of a third FET connected to the input photocurrent. The output voltage responds as a function of the light intensity at the photodetector while the bias voltage determines the range of light intensity for normal operation of the photosensor circuit. In a photosensor array with an appropriate bias current, the image scene contrast is amplified while the photosensor circuits automatically adapt to the overall light intensity.

Patent CA-2186321-A1 (CA)
Inventor: FOSTER JAMES JOSEPH
IPC: D21C5/02
Filed: 1996-09-24
Abstract: This  invention relates  to  recently  developed systems which produced bleached recycled fibers from high lignin  content  recovered  paper materials  such  as  old corrugated containers and old newspapers.  Such systems of this type, generally, use chemical digestion (e.g.,  the kraft process)  to reduce  the  lignin content  prior  to bleaching.  Since recovered paper materials normally have high levels of aluminum, which are derived from the paper sizing and pH control chemical, aluminum sulfate; and since soluble aluminum causes scaling of evaporators in the kraft digestion-chemical recovery cycle, there is a need for a means to remove soluble aluminum from the recovered paper materials prior to digestion.

Abstract: The backup tong 10, 110 includes a fluid powered cylinder assembly 72, 172. A wedge 80, 180 is provided at the end of a cylinder rod 76, 176 and forces multiple dies into gripping engagement with the tubular. A pair of links 30, 32 or 130, 132 are driven laterally outward from the centerline 28, 128 of the tong body by thewedge 80, 180, thereby forcing the dies to bite the tubular. The design of the tong is relatively simple and has few moving parts, yet is highly rugged and dependable. Dies 62, 64 and 66 or 162, 164 and 166 may together provide circumferential engagement of at least 270° with a tubular, thereby reliably gripping and minimizing damage to the tubular. The tong 10 includes a door jaw latch pin 58, and is particularly well suited for use on dual tubing strings where there is little axial spacing between the tubing strings.

Title: Hypodermic syringe
Inventor: FEARIS PAUL JAMES
IPC: A61M5/178
Filed: 1995-05-04
Abstract: A syringe for the injection or taking of fluids is shown in the figure. The syringe has a needle mounting endpiece (13) which is detachably coupled to barrel (10) by mating features (24 and 25). Plunger (11) and coupled seal (12) are guided by flanges (16 to 19) sliding within guides (20 to 23) and are further guided by protrusions (67 and 68) so as to prevent rotation of plunger (10) and prevent unwanted contact between flanges (16-19) and barrel (10). The plunger exhibits a bayonet-type fixture (32) which will upon rotation engage within endpiece (13) and allow retraction of the endpiece and coupled needed (15) within barrel (10). Following engagement and retraction the plunger may be prevented from movement by the engagement of protrusion (59 and 63) on barrel protrusions (67 and 68) and abutment of radial protrusions (91 and 92) against annular protrusions (39-42). Further figures demonstrate embodiments and improvements of this design.

Filed: 1997-01-29
Abstract: The present invention provides a method for forming a pattern on a synthetic wood board to form, on a surface of the synthetic wood board, a pattern such as wooden grain and the like which is close to natural wood, to enhance the reality of woody like appearance. The synthetic wood board is formed by mixing 35- 80 wt% of thermoplastic resin material and 20- 65 wt%. By a first grinding process, the synthetic wood board is formed at its entire surface of at least one side thereof with a large number of wound stripes in one direction. By a colorant coating process, a colorant is coated on the surface on which said wound stripes are formed, the colorant impregnates in wood meal on the surface to generate blur. And some colorant remain in recessportion of the wound stripes to form recess pigment layer. By a second grinding process, the entire surface on which the colorant is coated is ground and abraded except the recess pigment layer to form a large number of the wound stripes, thereby forming a pattern having woody like appearance. By a woody grain printing process, a woodygrain pattern is printed on the abraded surface. With these process, a pattern having woody like appearance is formed by synergism of the pattern and woody grain pattern.
