Title: Welding device with arc termination control
Inventor: LAABS ADAM P
IPC: B23K9/10
Filed: 2007-04-10
Abstract: A welding-type apparatus and method providing controlled termination of a welding-type process includes monitoring an arc parameter and setting a threshold based on the monitored arc parameter. When the arc parameter achieves the threshold, weld power is gradually reduced until arc termination. The system provides for a controlled arc termination process which is dynamically defined by the characteristics of each welding arc.

Abstract: A practice putting green that is adjustable to provide a playing surface having a variety of contours. The assembly is formed of a plurality of narrow transverse support members that are arranged as segments in side-to-side relationship to define an elongate playing path. Carpet, artificial turf or other flexible material is placed atop the support members to form the playing surface. Inwardly facing wedges are mounted under the ends of the support members and are slid from side-to-side so as to selectively tilt the members and adjust the contour of the playing surface. The wedges on each segment are joined by a transverse rod so that both will move simultaneously in response to pressure on one of the wedges. The support members have a tray-shaped configuration with upwardly extending end walls, so that in combination they define an elongate channel. The layer of pliable material is received in the channel so that the edges thereof engage the walls of the channel on either side so as to hold the support members against shifting out of alignment from side-to-side.

Title: A computer-implemented method of design of surfaces defined by guiding curves
Inventor: RAMEAU JEAN-FRANCOIS
IPC: G05B19/4097
Filed: 2009-07-03
Abstract: The invention relates to a method of design of ruled surfaces, comprising a step of accessing data defining guiding curves P(u) and Q(v) (S 110) and a cost function f(t, w) (S120). Given P(u) and Q(v), the unknown coupling is a parameterized curve s ~(t(s), w(s)). The method further comprises defining (S200) an objective function of the type J = J( f, t, w), involving both f(t, w) and coordinates t, w of the coupling curve.  Then, optimizing the objective function J makes it possible to obtain the target coupling curve (S400). Finally, a ruled surface S(s,.lambda.) =.lambda.Q(w(s)) + (1-.lambda.)P(t(s)) is provided (S500), according to the guiding curves P(t(s)) and Q(w(s)), composed with the coordinates t, w of the coupling curve previously obtained. In addition, the objective function is further constrained at the optimization step (S200 - S400) such that arguments t, w of the cost function f(t, w) are regulated by a regulation function µ.   The invention generalizes to any surface defined by guiding curves and further concerns a computerized system and a computer program product comprising means adapted for implementing the method of the invention.

Patent CA-2684786-A1 (CA)
Inventor: GAREIS MARC
IPC: B23P19/06
Filed: 2008-04-23
Abstract: The invention relates to a power screwdriver (10) comprising a motor (12) as the drive, a desired torque default element (52) and an actual torque determination element (46), a torque gradient determination element (48) and a motor control (40) which controls the motor (12) depending on the torque gradient (dmd_lst/dt). The invention is characterized by a torque threshold determination element (50) which provides a torque threshold value (Md_Lim, Md_Lim1, Md_Lim2) that depends on the torque gradient (dmd_lst/dt) and lies below the desired torque value (Md_Soll). If the actual torque value (md_Ist) exceeds the torque threshold value (Md_Lim, Md_Lim1, Md_Lim2), a motor control (40) presets a speed reduction for the motor (12) or already completely switches off the motor (12). The power screwdriver (10) according to the invention avoids torque overshoots and yet allows the desired torque value (Md_Soll) to be exactly reached in the shortest time possible.
