Patent CA-2069908-A1 (CA)
Inventor: BLAESING HORST
IPC: C25D21/12
Filed: 1990-11-30
Abstract: A process and apparatus are disclosed for controlling the flow of operations in electroplating  plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes.  In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts which pass through the plant in succession and/or the distances between these parts are detected and the application of the electroplating currents is controlled as a function of these positions and/or distances by switching the anodes on and off, in such a manner that the flux density is approximately the same in all regions of the parts.

Title: Apparatus and methodology for producing rounded brush tips
Inventor: KIGYOS FRANK M
IPC: A46B3/18
Filed: 1990-12-13
Abstract: Apparatus and methodology for rounding the bristle tips of twisted wire brushes (26). Each twisted wire brush is mounted in a carrier (22) by means of a spindle (28) which permits the brush to be rotated along its longitudinal axis. The melting of the synthetic bristle tips takes place in a heated chamber (24) which includes one or more heated cylindrical cavities (38) which may extend over a portion or the whole of the length of each brush. When the carrier (22) approaches the chamber (24), the chamber is lowered over the carrier so that each of the individual brushes is inserted into a heated cavity (38). When inserted in the cavity the brush is rotated on the spindle (28) while it is heated. The rotation and heating causes the individual bristle tips to melt into a rounded ball without adhering to each other. Thereafter, the heating chamber (24) is raised, the carrier (22) indexed and the process repeated.
Patent CA-2073797-A1 (CA)
Title: Prosthetic implants with bioabsorbable coating
Inventor: DAVIDSON JAMES A
IPC: A61F2/00
Filed: 1992-07-14
Abstract: ABSTRACT: A novel coated prosthesis that can be tailored to avoid the problem of bone resorption caused by stress shielding.  The permanent, load-bearing skeletal replacement prosthesis is coated or covered with a bioabsorbable polymer at selected sites on its surface so that bone affixation is preferentially delayed at these covered sites and bone adjacent to uncoated areas are not stress shielded.  Thus, resorption is avoided. When the bioabsorbable polymer is gradually absorbed away, bone affixation takes place on the exposed surfaces, as needed.

Patent CA-2077517-A1 (CA)
Title: Toothbrush
Inventor: JEANNET ROLAND
IPC: F16B39/08
Filed: 1992-11-03
Abstract: The invention relates to a toothbrush (20), the brush head (22) of which can be removed from a brush handle (24).  A threaded pin (26) can be moved to a limited extent out of the brush handle (24), counter to the action of a prestressing spring (32), when the brush head (22) is screwed onto the said pin, until a stop catch (36) of the brush head (22) engages in a recess (38) of the brush handle (24) and locks the brush head in the rotational direction, while the prestressing spring (32) holds the brush head (22) under prestress against the brush handle (24).  A firm connection can thus be established simply and rapidly between the brush handle and the brush head, irrespective of the shape of these parts.

Patent CA-2080059-A1 (CA)
Inventor: DENT LARRY G
IPC: F16L21/04
Filed: 1992-10-07
Abstract: A cooperating combination of a metallic gland and a metallic grip ring is made to be effective in respect to both plastic pipe and metallic pipe used in fluid piping systems, which are primarily water and sewer piping systems, where these pipes are part of assembled restrained sealed bolted joints.  The grip ring, in one embodiment, has an internal diameter surface structure having at least two well spaced major size pipe  gripping circumferential teeth.  In another embodiment, the grip ring, in addition to the major teeth, has several spaced minor sized pipe gripping circumferential teeth located between and beyond the major sized teeth.  In reference to the embodiment having both sizes of teeth, when the installed grip ring is restraining a metallic pipe to keep it in a sealed bolted joint, only the well spaced major size pipe gripping circumferential teeth are, in part, penetrating the metallic pipe.  When this installed grip ring is restraining a plastic pipe to keep it in a sealed bolted joint, both the major size pipe gripping circumferential teeth and the minor size pipe gripping circumferential teeth are penetrating the plastic pipe.  The metallic grip ring has a radial open through slot to accommodate the subsequent reduction of the internal diameter thereof when the grip ring is in place.     In respect to plastic pipe, when the radial open through slot is closed, the gasket hag been sealed, all the pipe gripping circumferential teeth, both major size and minor size, are penetrating the plastic pipe, which is not over-stressed and which will remain in the sealed bolted joint.  The major size teeth are well spaced and fewer in number so they will successfully penetrate metallic pipe, which takes a lot of concentrated force, which is created when the fasteners of the bolted joint are tightened.  The minor size teeth, which are closer together, are needed to provide more tooth contact area to spread out the restraining forces needed to hold the relatively weaker plastic pipes within their respective restrained sealed bolted joints.  In respect to restraining metallic pipe, if minor size teeth are on the metallic grip ring, they always remain clear of the metallic pipe.
