Patent CA-2276272-A1 (CA)
Inventor: SCHNEIDER WILLIAM A JR
IPC: G01V1/28
Filed: 1998-03-03
Abstract: Computer-implemented methods of processing and imaging seismic data by migration and DMO (dip moveout) are subjected to quantitative evaluation. The evaluation is done by a computerized testing procedure. An impulse data set is formed containing a single "live" trace and zero amplitudes for other traces.  A selected velocity function is also generated. The impulse data set is then processed by the processing method being evaluated. Estimates of the vertical traveltime, amplitude and phase along each of the impulse-response events are then generated. The estimates so formed are compared against exact values obtained from a model using an integral equation which accurately describes migration of DMO. Users thus are provided with indications of how the processing techniques may be expected to perform on real data.

Title: Method of testing rotor bars in a squirrel cage electric motor
Inventor: KREPELA JAN
IPC: G01R31/34
Filed: 1999-12-16
Abstract: A method of testing rotor bars in a squirrel cage electric motor. An electric current is passed through a rotor cage, so that current flows through the rotor bars being tested. A relative strength of flux generated by the electric current passing through the rotor bars is compared. A marked difference in flux strength indicates a broken rotor bar. The method is of sufficient resolution as to leave no doubt as to when a rotor bar is damaged. By way of example, in one test a broken rotor bar recorded a reading of 25 millivolts, as compared with readings of 140 millivolts for all of the other rotor bars.

Abstract: The tamper evidency of a carton is increased by producing stronger end flap seals. This can be done by anchoring the adhesive onto at least one of the end flaps. In a preferred embodiment there is at least one lower flap (22a, 22b, 26a, 26b) with at least one recessed area (30), at least one seal flap (28a, 28b) with at least one aperture (32) and at least one top flap (24a, 24b). The lower flaps are folded inward followed by the seal flap. An adhesive is on the inner surface of the top flap which then is folded inward onto the seal flap.  The adhesive flows through the at least one aperture in the seal flap and spreads outwardly in the at least one recessed area below the at least one seal flap to become anchored to the seal flap. This is enchanted by a plurality of recesses in the at least one lower flap adjacent to the at least one aperture in the at least one seal flap. By being anchored to the seal flap and adhesively attached to the fiberboard underside of the top flap, a strong end seal is formed on the carton. This is highly tamper evident since flaps are permanently altered on opening the carton.

Title: Precoated controlled release fertilizers and processes for their preparation
Inventor: JOHNSON WILLIAM R
IPC: C05G5/00
Filed: 1999-06-09
Abstract: A controlled release fertilizer formed from nutrient granules having intermediate or precoat layers of organic oil, such as raw linseed oil, prior to application of a polymeric, encapsulating coat. The precoat may also contain a binding agent, such as a fine clay, and a drier. The new fertilizer composition is made by a process of applying the oil precoat, but not curing it until after the encapsulating coat is applied. The use of the precoat provides more desirable controlled (delayed) release characteristics at a lower weight of the encapsulating coat, particularly for nutrient cores having a relatively large number of surface imperfections or discontinuities.

Filed: 2000-03-24
Abstract: In a swash plate type compressor having a shoe interposed between a swash plate and a concave surface of a piston, the concave surface has a first and a second spherical surface which are adjacent to and offset from each other to make a slight step extending along the concave surface. The shoe has a spherically convex surface received in the concave surface. In a condition where the spherically convex surface is received in the concave surface, the slight step serves to cause a small gap between the spherically convex surface and a part of the first spherical surface. When the swash plate is rotated together with a rotary shaft, the shoe converts a rotation of the swash plate into a reciprocating motion of the piston.

Abstract: A vehicle/implement hitch control system is responsive to a wheel slip signal indicative of the slippage of the driven wheels of the vehicle. The control system generates an integrated slip signal using an integration function, generates a proportional slip signal using a proportional function, and generates a combined slip signal as a combination of the integrated slip signal and the proportional slip signal. An operator-controllable slip response adjuster generates slip response signals. A hitch control signal is generated as a function of the slip response signal and the combined slip signal, so that the operator can vary the response of the hitch control signal to the integrated slip signal, to a mixture of the integrated slip signal, and to various multiples of the proportional slip signal only.
