Patent CA-2339074-A1 (CA)
Title: Metallic flake containing coating compositions having improved glamour
Inventor: BERGE CHARLES T
IPC: C08K3/08
Filed: 2001-03-02
Abstract: This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier.  The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved. Furthermore, by controlling the molar ratio of the hydrophobic segment to the hydrophilic segment in the segmented copolymer and the solubility parameter of the hydrophobic segment, applicants have discovered that it is possible to use either a non-passivated aluminum flake or pre-passivated aluminum flake in the coating composition while improving glamour over conventional metallic paints and still maintaining the dispersion stability of the composition. As a result, formulator has substantial leeway in selecting from a wide array of environmentally acceptable solvents, film forming binders and components, which are typically added to a coating composition for improving the coating properties. The composition is most suited for use in automotive OEM and refinish metallic paints.

Title: Electronic proximity monitoring security apparatus
Inventor: VIBERG DAVID
IPC: G08B21/02
Filed: 2001-06-20
Abstract: A security system is disclosed which includes a transmitting device and a receiving device. The transmitting device generates a uniquely coded signal on a pseudorandom time interval and is attached to a person, pet or object. The associated receiver is placed near or carried by a person wishing to monitor this person, pet or object. The monitoring person will typically be close enough that he or she is well within the range of the transmitter.      If the person, pet or object with the attached RF transmitter is removed by some predetermined minimum distance from its associated RF receiver, the RF receiver will not receive the unique coded signal and will trigger an alarm. The receiver can be set to recognize several unique codes but will ignore all others. The transmitter can be set to different power levels to change the range over which the receiver will signal its alarm.

Title: Method of producing concrete blocks with textured surfaces
Inventor: BOTT TIMOTHY ALLEN
IPC: B28B11/08
Filed: 2001-06-18
Abstract: A method for creating decorative patterns on surfaces of cured concrete blocks includes a plurality of texturing elements secured to one or more rotatable shaft via a plurality of flexible support cables. Upon rotation of the shaft, centrifugal force causes the secured texturing elements to radially extend from the shaft. The blocks are preferably positioned such that the rotating texturing elements repeatedly come into contact with particular surfaces of the blocks, thereby forming a textured or antiqued pattern on such block surfaces. In a particular embodiment, the rotatable shaft is reciprocally moved in a direction parallel to the block surfaces to be patterned, whereby an entire block surface is exposed to the rotating texturing elements.

Title: Method for forming a short-radius bend in flanged sheet metal member
Inventor: LEEK WILLIAM F
IPC: B21D11/10
Filed: 2000-03-10
Abstract: One or more closed perimeter openings (6;  106) are formed in the compression area of a flange (8) of a member (1) that is to be bent transversely to the flange (8). The member is bent along a transverse bend line (14), and the flanges (8; 108) are bent inwardly on themselves.  The bending of the member along the transverse bend line (14) is done with a great force, and because portions of the side flanges are supported on their distal and proximal side (10, 11; 110, 111), the material of the side flanges (8, 108) in the compression area plasticizes and flows into the closed perimeter opening (6; 106), causing them to deform. Because the closed perimeter opening or openings (6; 106) are present, the side flanges (8;  108) are compressed in a more controlled manner, reducing cracking, wrinkling and thinning during the bending of the member (1) along the transverse bend line (14).
