Patent CA-1292581-C (CA)
Title: Color-matched printing
Inventor: MYERS ROBIN D
IPC: H04N1/60
Filed: 1987-09-02
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE A technique is disclosed for matching a color, applicable for example to printing a color which matches a color on a CRT display. Quantities of toners which will generate the matching color are determined and then a pattern of toners which will approximate those quantities is applied. To determine the quantities, a definition of the original color, such as its RGB coordinates, is converted to coordinates in a linear mixing space, such as CIE coordinates. These coordinates, together with coordinates of the toners are then used to calculate quantities of toners which will produce a matching color. The calculations match hue, saturation and reflectance so that the matching color appears like the original color and so that characteristics of an original image are preserved. A table containing the area covarages of available toner patterns is used in selecting the toner pattern. A separate pattern for each toner may be selected by comparing the quantity of that toner with the area coverages of its available patterns to find the separate toner pattern which will come closest to that quantity. The selected separate patterns of the toners are then combined to obtain a combined toner pattern, which is then applied.

Abstract: ABSTRACT OF THE DISCLOSURE      A process and apparatus for making hot-rolled steel strip from a striplike continuously cast starting material is described which uses successive processing steps in which the striplike cast starting material after solidification is brought to the hot rolling temperature and fed to a multi-stand rolling mill for rolling to the finished rolled product. A continuous casting unit supplies the multi-stand rolling mill.          The rolling to the finished rolled product occurs continuously in three or four roll stands at maximum with the largest possible reduction per pass. The first two roll stands operate with an approximately maximum rolling moment and a large working roll diameter.

Title: Transfer switch
Inventor: THOMSON ROBERT G
IPC: H01H9/26
Filed: 1987-12-21
Granted: 1990-12-27
Abstract: TRANSFER SWITCH                 ABSTRACT OF THE DISCLOSURE         The transfer switch assembly typically automatically transfers electrical loads from a normal electrical power source to an emergency electrical power source upon reduction or loss of normal power source voltage. It can also automatically re-transfer the load to the normal power source when the normal voltage has been restored within acceptable limits. The device includes a rotor and couplers for cooperating with switch toggles of circuit breakers to actuate the circuit breakers.  First and second links connect the rotor to the couplers. The links have outer ends connected to the couplers, and inner ends hingedly connected to the rotor at positions spaced circumferentially apart relative to the rotor axis. In this way, rotation of the rotor means in one direction moves the couplers to open one circuit breaker and, after a short period of time, to close the remaining circuit breaker so that one circuit breaker opens prior to closing the other circuit breaker.  The transfer switch can also be actuated manually.

Abstract: Abstract of the Disclosure Escherichia coli carrying a hybrid plasmid having been constructed by inserting a desired foreign gene into an expression vector so as to permitting expression of said desired foreign gene therein was cultured in a medium containing a sugar component utilizable by the E. coli as a carbon source at a concentration of 0.3% or more so that the expression of said desired foreign gene was suppressed.  This E. coll (i.e., transformant) was cultured in the medium in which the sugar concentration was maintained at 0.3%or more in a first process so as to supress the suppression of the foreign gene and to support sufficient cell growth and thereafter at less than 0.3% in a second process to release the suppression of the expression so as to permit effective production of the foreign gene product, which resulted in high concentration of the foreign gene product in the final culture.

Title: Anvil and driver assembly for a surgical skin stapling instrument
Inventor: BRINKERHOFF RONALD J
IPC: A61B17/068
Filed: 1988-03-21
Granted: 1991-05-07
Abstract: AN IMPROVED ANVIL AND DRIVER ASSEMBLY FOR A SURGICAL SKIN STAPLING INSTRUMENT              ABSTRACT OF THE DISCLOSURE   An anvil and driver assembly for a surgical skin stapling instrument producing formed and implanted skin staples of more consistant and perfect configuration. The anvil provides an anvil surface which supports the crown of the staple during the forming operation.  The driver has an inverted U-shaped notch formed therein which defines parallel side edges to bend the staple legs about the anvil and a transverse edge joining the side edges and adapted to contact the crown of the staple near the end of the forming operation.  In the anvil and driver assembly of the present invention, the clearance between the parallel bending edges of the driver and the adjacent anvil edges is greater than the transverse dimension of the staple wire.  The anvil surface of the anvil is concave and the crown contacting edge of the driver is so configured as to impart a temporary bow in the staple crown near the bottom of the driver stroke, which bow is of such dimension as to preclude plastic deformation of the crown.  This produces a more generous bend and a slight over-bend at the junctures of the staple legs and the crown such that when the crown is released by the driver and returns to its rectilinear state, this action of the crown will compensate for the natural spring-back properties of the material from which the staple is made at the above noted junctures, consistantly producing the desired final formed configuration of the staple.

Abstract: ABSTRACT             A double-diaphragm pump is designed to be molded almost entirely out of plastic and is provided with totally externally-accessible and serviceable check valves which do not require any significant disassembly of the pump itself. The pump is also fitted with a diaphragm which is formed from a uniform thickness of material and which have convolutions which are equally disposed on either side of the angle of elevation of the unstressed diaphragm. The pump is designed for mounting on top of a barrel or drum and has a set of radiused feet so as to fit snugly against the rim in an inlet pipe which fits into a bung plug having an eccentric opening such that the opening grips the inlet pipe and the plug may be rotated so as to snugly position the pump against the rim of the drum. The air valve to the pump is provided with U-cup seals in the housing. The spool of the pump moves in such a fashion so that the transitional area between the open and closed positions contacts the open end of the U-cup rather than the closed end as is traditional.
