Patent CA-2244471-C (CA)
Title: Protective pole caps for utility poles
Inventor: KRIEGER HARTMUT
IPC: E04H12/04
Filed: 1998-08-06
Granted: 2003-03-11
Abstract: A protective pole cap for installation onto the top of a utility pole has a downwardly-open, cup-shaped body formed with radially inwardly and upwardly projecting, resiliently deflectable finger-shaped projections for releasible gripping engagement with the top end portion of a pole. An external projection on the cap forms an eye for engagement by a installation pole, thus allowing one-man installation, even onto an in-service pole without disconnecting power, and without any mechanical fasteners. A tear-out panel at one side of the cup-shaped body is removable from the cup-shaped body to form a slot for accommodating a sky pin on the pole.

Title: Transdermal therapeutic system with small application-area thickness and great flexibility, and production process
Inventor: VON KLEINSORGEN REINHARD
IPC: B32B3/10
Filed: 1997-03-12
Granted: 2006-10-31
Abstract: A transdermal therapeutic system for the release of active substances to a substrate is characterized by the structure of the system comprising a substrate (1) provided with a separating layer (2), a film layer (3) comprising the active substance, and a protective layer (4) provided with a nonstick finish, the separating layer (2) consisting of a material whose bond to the film layer (3) may be abolished. By means of printing methods, such systems having small application thickness and high flexibility can be manufactured, it being possible to provide a substrate that has been rendered abhesive as an alternative to the substrate/separating layer-complex. A printing method limiting the active substance-containing region to the application site reduces disposal problems.

Abstract: A method and apparatus for stopping a welding process includes monitoring the status of the arc. The output current is commanded to a level sufficient to clear a short if a short circuit forms when the process is stopping.    A low current level is commanded after the short has cleared. The low current level is sufficiently low to prevent the forming of a large ball. This is repeated until a short does not form. The wire feed speed is monitored, and the stopping process begins when the wire feed speed drops below a threshold. The stopping process is performed with, a MIG process, a pulsed spray process, and a short circuit transfer welding process. The arc voltage is monitored to determine the status of the arc. The motor is commanded to stop in response to receiving a user provided stop command, and the braking of the motor is controlled.      At least one output parameter may be reduced before the threshold is reached, but after receiving the stop signal in another alternative embodiment.

Abstract: A method for attenuating water column reverberations in a dual sensor seismic signal, whereby a pressure signal and a velocity signal are transformed from the time domain to the frequency domain, generating a transformed pressure signal and a transformed velocity signal, respectively. Values for weighting factors K p and K v are selected and multiplied times the transformed pressure signal and the transformed velocity signal, respectively, generating a weighted pressure signal and a weighted velocity signal, respectively. The weighted pressure signal and the weighted velocity signal are summed, generating a summed signal. Values for ocean bottom reflectivity R and Z, the frequency domain delay operator for two-way travel time in the water layer, are determined. A weighted inverse Backus filter is calculated and multiplied times the summed signal, generating a filtered signal. The filtered signal is transformed from the frequency domain to the time domain.

Title: Rotary mower conditioner having improved cut crop flow
Inventor: O'HALLORAN MICHAEL L
IPC: A01D43/10
Filed: 1999-08-31
Granted: 2004-04-13
Abstract: A mower conditioner includes a rotary style cutter bed and a pair of laterally extending crop conditioning rolls spaced rearwardly from the cutte r bed. Crop flow is improved in the machine by a laterally extending conveying roller located between the cutter bed and the nip defined by the conditioning rolls. In particular, the conveying roller serves to lift cut crop up from the cutter bed and convey t he crop rearwardly to the nip. This ensures that the cut crop moves in a steady stre am from the cutter bed to the conditioning rolls, and thereby reduces the risk of cut cr op being thrown forwardly by the cutters. A downwardly open area is preferably define d between the conveying roller and the cutter bed to provide a space through which dirt and debris can drop out of the machine. The conveying roller preferably has a rotational axis that is lower than the rotational axis of the lower conditioning roll and generally vertically aligned with the substantially planar cutting zone defined by the cutter bed.

Title: Apparatus and method for conductivity measurement including probe contamination compensation
Inventor: CHAN WAI YIN CEDRIC
IPC: G01R27/22
Filed: 1999-05-07
Granted: 2011-05-03
Abstract: A conductivity measurement system provides one or more DC pulses to first and second electrodes submerged in an aqueous solution such as, for instance, the wash water of an industrial dishwasher. The voltage at the first electrode is measured at first and second predetermined times after initiation of DC  pulse(s). Linear regression of the first and second measured voltages is used to calculate the voltage at the first electrode at the beginning of the DC  pulse(s), i.e., at time t=0. The resulting voltage at time t=0 is then used to calculate the conductivity of the solution, thereby compensating for the effects of polarization. Further, the difference between the respective first and second measured voltages is compared to a predetermined threshold value to determine whether the electrodes are so contaminated that polarization compensation is no longer feasible, thereby signaling that the electrodes should be cleaned or replaced.
