Title: Scoop with weigh scale
Inventor: SHYMKO WAYNE W
IPC: G01G19/56
Filed: 1999-08-02
Abstract: A scoop has a handle attached thereto by a neck.      The neck has a built in strain gauge supporting the scoop which measures weight in the scoop. An analog-digital converter converts the strain gauge output to a digital signal, which displays the weight as a readout (either metric or avoirdupois) on a panel in the handle. Control switches built into the handle or panel control the functions of the scoop, while indicator/annunciator lights indicate status. A level indicator is provided having a ball bearing resting freely on a conducting bottom plate forming a spherical sector of predetermined angle and a cylindrical sidewall having therein conducting elements. When the ball bearing contacts a sidewall conducting element it closes a circuit which switches off a level indicator/annunciator light, which when on shows that the scoop is level. The position of the ball bearing is visible to the operator, allowing correction of tilt. The predetermined angle is set between 8 and 12°, so that tilts greater than 4 or 6° are visually indicated.

Title: Dual acting implement leveling system with transport stabilization
Inventor: BIERL JAMES FRANKLIN
IPC: A01B63/16
Filed: 1999-08-31
Abstract: A dual action leveling system for a disk or similar implement connected between the hitch and the lift wheel assembly includes a transport stop for providing a fixed hitch position for good transport leveling and stability. The system includes a fore-and-aft extending member with first and second coil springs and an adjustable spring abutment member threaded through one end of a rod for providing leveling for different ground conditions. Weight can be transferred to and from the front of the implement by simply turning a crank located at one end of the rod. For example, weight can be transferred to the front of the implement to provide compensation for added weight of a rear mounted attachment. The spring structure provides a self-compensating effect which resists changes in front-to-rear implement leveling with changes in ground conditions.

Title: Arc thermal spray gun extension with conical spray
Inventor: BENARY RAPHAEL
IPC: B05B7/18
Filed: 1999-12-14
Abstract: In a two-wire arc spray extension two metal wires are guided into contact, and a gas cap is affixed to a gun body. The feeding wires receive an arc current to effect an arc and thereby molten metal at the wire tips. The gas cap has a plurality of orifices therein that receive pressurized gas to generate gas jets. The orifices are disposed with substantially equal spacing arcuately such that the jets are directed with a radially inward component toward the tips to effect atomization of the molten metal into a spray stream. The orifices have axes that are offset forwardly and tangentially from radial so as to create a vortex flow such that the spray stream is effected in the form of a conical fan. Insertion of the spray stream centrally into a hole can effect a coating circumferentially on an inside surface of the hole.
Patent CA-2294745-A1 (CA)
Inventor: HYLL MATTIAS
IPC: G06F17/14
Filed: 1998-07-02
Abstract: The present invention significantly reduces the number of complex computations that must be performed in computing the discrete Fourier transform (DFT) and inverse DFT (IDFT) operations. In particular, the DFT and IDFT operations are computed using the same computing device. The computation operations are substantially identical for both operations with the exception that for the IDFT operation, the data are complex conjugated before and after processing. Using the same computing device/operations, both DFT and IDFT computations are optimized for maximum efficiency. A common transform process is selectively connected to first and second data processing paths. A DFT operation is performed on an N-point sequence on the first data processing path, and an IDFT operation is performed on an N-point sequence on the second data processing path using the same N-point fast Fourier transform (FFT).
