Patent CA-2601055-A1 (CA)
Title: Numeric control engraving machine
Inventor: DI BENEDETTO LEONARDO LUIS
IPC: B23C5/26
Filed: 2006-03-15
Abstract: The invention relates to a digitally-controlled engraving machine which can be used to engrave different objects such as gems, plates of metal or another material, such as to produce the effect obtained by means of artisan engraving with a chisel, in which the tradesperson performs a downward/upward movement with the chisel with each insertion made in the surface of the body to be engraved, such that the engraved line has a curvilinear trajectory. In addition to the three axes (X, Y, Z) or degrees of freedom for the movement of the tool holder, the inventive engraving machine also creates two new complementary axes which are denoted as PT (depth of line) and SV (vector tracing), thereby producing the same type of engraving as that obtained by a tradesperson with a chisel. The PT axis controls the penetration movement of the tool for the curvilinear line over the course of the vector that defines the direction and sense of the line. The SV (vector tracing) axis orients the cutting edge of the tool with the correct engraving cutting angle.

Title: Spring driven ram for closing an electrical switching apparatus
Inventor: WEHRLI HENRY A III
IPC: H01H71/10
Filed: 2008-03-28
Abstract: An operating mechanism closing assembly for an electrical switching apparatus having a ram assembly structured to engage and move a toggle assembly is provided. The ram assembly includes a ram body that travels over a, preferably, straight path and engages the toggle assembly. The path may be defined by one or more pins extending through the ram body. One or more springs are coupled to the ram body and bias the ram body toward the toggle assembly. The springs may be conveniently disposed about the pins. In this configuration, the force created by the springs is, essentially, applied directly to the toggle assembly. The toggle assembly is coupled to, and structured to rotate, a pole shaft that is further coupled to, and structured to actuate, the electrical switching apparatus contacts.  Accordingly, because the force created by the springs is not transferred via one or more cams, the required force, and therefore the size of the springs, is reduced compared to the prior art.

Title: Method of evaluating the effects of exogenous and endogenous factors on the skin
Inventor: AFRIAT ISABELLE
IPC: G01N33/483
Filed: 2006-12-05
Abstract: The present invention provides non-invasive, in vivo, DISC-type methods of evaluating structural changes in skin due to a variety of exogenous or endogenous factors. It is possible to develop quantitative and qualitative characterizations of skin. For example, the skin may be characterized based on its structural age rather than its chronological age. Based on the structural age and type of an individual's skin, cosmetic, dermatologic, medicinal or manipulative treatment may be customized. The method is based, in part, on quantification of discontinuities that arise in the skin during normal facial expression. The methods provide for evaluating changes in human skin response that occur over a short term (one day) or long term (one or more years). The methods provide for evaluating the skin's response to cosmetic, dermatologic or medicinal treatment or to any other factor alleged to affect the skin.

Title: System, apparatus and method for flameless combustion absent catalyst or high temperature oxidants
Inventor: GIBSON ROBERT L
IPC: F23L15/00
Filed: 2007-01-03
Abstract: A system, apparatus and method whereby flameless combustion is precipitated and maintained in a combustion chamber having a surface that is either convex concave, straight or any combination thereof without the need for catalysts or high temperature oxidants. The apparatus allows the combustion chamber to operate in a conventional combustion mode and a flameless combustion mode. The method provides for hot air and fuel gas to both be inerted prior to their mixing so long as their blend temperatures are within the 10000F to the 14000F range. The inert hot air and the inert fuel gas flow side by side along the chamber's internal surface so that the two gases mix more uniformly, thereby allowing flameless combustion at lower temperatures resulting in low NOx emissions.

IPC: E04G21/00
Filed: 2008-08-15
Abstract: A cavity wall spacer, a building structure and method are disclosed. The cavity wall spacer determines a separation of building elements of two leaves of a wall during construction. The cavity wall spacer comprises: a support body; and a plurality of spaced projections upstanding from the support body and operable to extend across a cavity between the two leaves, each projection having a recessed channel operable to inhibit transfer of moisture from one end of each projection to another. The recessed channel or groove helps to prevent the passage of moisture along the length of the projection which provides an efficient way of preventing moisture travelling between the two leaves of the wall. Also, a recessed channel reduces the amount of moisture which drips into the cavity since the moisture is more likely to track back along the surface of the projection. Additionally, providing a recessed channel ensures no external obstruction on the projections which helps to achieve a significantly improved stacking density. Furthermore, the projections are less prone to any damage since there are no external protrusions.
