Patent CA-2158788-A1 (CA)
Title: Flip-Up C Shank Standard for a Cultivator
Inventor: NOONAN JAMES THOMAS
IPC: A01B35/22
Filed: 1995-09-21
Abstract: A  simple, light-weight C-shank standard is mounted on a bracket which is corner clamped to a rig cross tube on a row crop cultivator.  A pin inserted through apertures in the bracket maintains the shank in a preselected field-working attitude.  The pin can be removed to allow the shank to be pivoted upwardly for maintenance, sweep removal, or residue removal.  The shank can be supported in the raised position by the pin when the cultivator configuration is changed for cultivation in lay-by conditions, or for operation in skip row or other special crop configurations.  In one embodiment of the invention, the shank is edgebent and selective placement of the pin through one of a plurality of sets of mating holes in the bracket and the upper portion of the shank permits adjustment of the working position of the shank.  A mounting slot at the lower end of the one embodiment of the shank provides pitch adjustment for the earthworking tool.

IPC: E21B4/14
Filed: 1995-10-04
Abstract: A pneumatic ground piercing tool has a reversing mechanism than can be operated by remote control but which does not contain a moving valve member inside the tool which become jammed. Such a tool generally includes, as essential components, an elongated tubular housing having a rear opening, a striker disposed for reciprocation within an internal chamber of the housing to impart impacts to a rear impact surface of the anvil for driving the body through the ground, an air distributing mechanism for effecting reciprocation of the striker, a tail assembly mounted in a rear end opening of the housing that secures the striker and air distributing mechanism in the housing, and a reversing mechanism including a supplemental air line capable of supplying compressed air for reverse operation to a radial port in the air distributing mechanism. Opening the supplemental air line to the atmosphere produces a short stroke forward mode of operation useful for operations wherein a less forceful impact is desirable.

Title: An arrangement for optic measuring of both width and thickness of an object moving along a straight path
Inventor: RYDNINGEN TONI
IPC: G01B11/02
Filed: 1994-04-15
Abstract: A method for touchless measuring of thickness and width of an object travelling along a straight path, based on the use of CCD video camera and laser. The invention is a unit in accordance with the Figure which, by means of installed cameras, laser(s) and two parabola-shaped mirrors, measures both thickness and width of an object as the centre line thereof passes directly below the width measuring camera, camera 1 in the Figure. The device is intended to be coupled to a computer or PC or PLS. Communicating equipment does not become "stuck", occupied with reading measuring values even if the object to be measured becomes laying at rest within the measuring area. Parabola-shaped mirrors are mounted such that they are parallel in the longitudinal direction, and with the concave and mirror-coated sides angled 90° to each other in the plane of the short sides (short dimensions); further, these are positioned with the longitudinal direction parallel with the transport direction of the object to be measured and above the same, such that light and contrast transitions are mirrored in these and recorded by camera 1. The device may be used for e.g. measuring thickness and width of laterally conveyed timber in adjusting works.

Patent CA-2167010-A1 (CA)
Inventor: MEDERO RICHARD
IPC: A61B5/0225
Filed: 1996-01-11
Abstract: An automated sphygmomanometer in which the so-called "air effect" (a slow rise or fall in cuff pressure caused by step inflates or deflates) is substantially eliminated by deflating (inflating) the pressure cuff to a pressure lower (higher) than the target pressure, waiting a short time interval, and then inflating (deflating) the pressure cuff to the target pressure. The driving force that causes the air effect to settle out after a step inflate or deflate is proportional to the size of the step change in pressure and is thus greatest during the wait time before the pressure cuff is inflated or deflated to the target pressure. Once at the target pressure, the remaining air effect is counteracted by the incremental air effect introduced by the latter inflate or deflate so that the air effect cancels out. The techniques of the invention provide most improved results for large inflates and deflates of 20mm Hg or more or first deflates after a complete inflate of the pressure cuff where the air effects are most pronounced.

Title: Method of reducing metal oxide in a rotary hearth furnace heated by an oxidizing flame
Inventor: KUNDRAT DAVID M
IPC: C21B13/08
Filed: 1996-05-03
Abstract: Method of reducing metal oxide in a rotary hearth furnace (14) to make a feed stock for a refining vessel when manufacturing alloyed iron, alloyed steel or stainless steel. The rotary hearth furnace includes an annular inner refractory wall (32), an annular outer refractory wall (34), an annular refractory platform(33) between the two walls. Stationary fuel burners (36, 40) are mounted to walls (32, 34) at a position just above an upper surface of the platform. A mixture of a metal oxide and a carbonaceous reductant is placed onto the upper surface of the platform and rotated past the burners. The oxide is heated by an oxidizing flame. Thereafter, a second layer of a reductant is charged over the hot first layer, and both layers are heated for an additional period of time to a temperature of at least 1300°C to reduce the metal oxide. The metal oxide may be chromium ore, chromium ore concentrate, nickel ore, nickel ore concentrate and stainless steel flue dust. The reductant may be coal or coke. The reduced metals provide inexpensive metal units for alloying with molten iron.

The artwork representation can be converted into a turn point polygon (TPP) format for effective data handling and modification of the artwork representation, and the TPP format can then be can be converted to a rectangular representation. A laser can be controlled in accordance with the rectangular representation of the modified artwork.

Title: QPSK Demodulator for Obtaining Phase by Arithmetic Operation
Inventor: DOI MASAYUKI
IPC: H04L27/22
Filed: 1996-07-10
Abstract: A QPSK demodulator that can be made smaller in size and lower in cost by restricting a storage capacity needed for a TAN-1 ROM to a minimum. Values of I and Q channel base band signals obtained by converting and quantizing a received signal is approximated to a nearest one of values on (2N-3 + 1) segment lines represented by Q=(n/2N-3)I, where n=0, 1, ..., 2N-3, with a phase accuracy of positive N bits.  Data corresponding to the approximated segment line is previously stored in a TAN-1 ROM as phase arithmetic data.  An address decoder converts each base band signal into an address.  An arithmetic circuit obtains phase data, for obtaining a QPSK demodulated signal, by performing a predetermined arithmetic operation, which is commensurate with the size of I and Q channel base band signals, on phase arithmetic data stored in the TAN-1 ROM in association with the converted address.
