Patent CA-2042230-A1 (CA)
Title: Computed tomography system with translatable focal spot
Inventor: LONN ALBERT H R
IPC: G06T1/00
Filed: 1991-05-09
Abstract: Abstract of the Disclosure A CT apparatus for reducing aliasing in reconstructed images uses an x-ray tube with a translatable focal spot to double the spatial sampling rate, over that achieved by a conventional CT machine, by acquiring a first and second projection corresponding to two different focal spot positions.  The amount of gantry rotation and the translation distance of the focal spot are coordination so that the projections are interlaced and the resulting combined projection is geometrically indistinguishable from a conventional projection with twice the spatial sampling rate.      The distance the focal spot is translated is further adjusted to eliminate redundant projections and provide adequate data acquisition time.

Title: Guardrail support bracket
Inventor: FLEURY HENRI-PAUL
IPC: A01K3/00
Filed: 1990-05-30
Abstract: ABSTRACT     A bracket for mounting a roadway guardrail to a post adjacent a roadway involves a generally rectangular backing member having an inwardly-extending flange extending along each of the upper and lower edges thereof. The bracket can be interposed between, preferably, a W-shaped guardrail and the post with the upper and lower edges of the guardrail being located adjacent the upper and lower flanges of the bracket respectively. The normal guardrail-mounting bolt will extend through the guardrail, a central aperture in the bracket, and the mounting post for clamping the guardrail end bracket to the post. Upon the impact, particularly sliding impact from a snowplow or the like, the upper and lower edges of the guardrail will contact the flanges and further deformation thereof will be resisted by the flanges. Thus the guardrail which would otherwise be detrimentally deformed by minor impacts will now retain its shock-absorbing capabilities, such detrimental deformation having been resisted by the back of the invention.

Abstract: IMPROVED WAND READERS                  Abstract of the Disclosure The  method  and  apparatus  of  this  invention facilitate operation of a bar code reader over a wider range of working angle and for a wider range of bar code densities.  The invention includes improved optics and sensing elements.  The optics and sensing elements and/or the associated circuitr? are arranged to provide two channels of data derived form the scanned bar code. The two channels have differing resolutions.  Analysis of the data from the two channels provides a single decoded result.  As the working angle and density vary at least one of the resolutions will be appropriate for sensing all or most of the bar coded data.   The data from the channel producing a valid result can be used, or  if  neither  channel  produces  a  valid  result  by itself,  data  from each  channel  can be analyzed and valid portions of the data from both channels combined to produce the single decoded result.

Title: Apparatus for stripping scrap from die cut blanks
Inventor: MARSCHKE CARL R
IPC: B31B1/14
Filed: 1990-09-18
Abstract: An apparatus for stripping the scrap portion from a die cut blank includes a stripper pin carrier providing a pattern of stripper pins supported in a resilient compressible material layer in which the stripper pins are demountably embedded. The stripper pins may be inserted into the resilient layer to provide a pattern or patterns which will accommodate virtually any size, shape and location of scrap portions to be stripped from a blank. The stripper pins can be removed and reinserted in a different pattern to accommodate a different run of blanks of corrugated paperboard of the like. Programmable robotic control may be used for pin placement and removal. A unique positive stripping apparatus includes a resilient soft-covered roll beneath the blank at the point of stripping and into which the leading edge of the scrap portion is pressed by the stripper pins on the upper rotary pin-carrying roll.  The stripping pins initially displace the leading edge of the scrap portion from the plane of the blank and into the soft layer of the roll until the edge is captured by the stripping edge of a downstream scrap carrier. The scrap carrier traps the scrap portion against the soft deformable layer of the lower roll and continued rotation of the roll effects a positive stripping of the scrap from the blank and carries the scrap away for disposal.  Supplemental indexing of the stripper pin carrier is utilized to assure fresh pin placement areas in the resilient material layer to eliminate inaccuracies in pin placement or poor pin retention because of material wear through repeated use.
