Patent CA-2173379-A1 (CA)
Inventor: RAWSON RAY
IPC: A01B49/06
Filed: 1996-04-03
Abstract: An apparatus and process for manipulating and clearing crop residue or other debris from a zone of soil before tilling the zone of soil to form a seedbed.  The apparatus may be attached to the tool bar of a farm implement and includes a pair of fingered wheels which are rotated by the ground and manipulate the crop residue as the apparatus moves along the ground.  A rotating coulter blade is disposed behind and between the wheels, and the wheels pull the residue rearward and press it against the soil surface where it is cut by the rotating coulter blade.  The coulter blade cuts the residue into several portions at least some of which are thrown outward away from the zone of soil to be tilled.  A zone tillage apparatus then tills, mixes, aerates and fertilizes the soil in the zone to form a fertilized seedbed, and a planter places seed in the seedbed, all of these procedures being carried out in one pass along the soil.

Patent CA-2180534-A1 (CA)
Title: Method and System for Manufacturing a Dry-Formed Fibrous Web
Inventor: MOSGAARD CHRISTENSEN JOHN HARD
IPC: D04H1/68
Filed: 1995-01-06
Abstract: For the manufacturing of dry-formed webs of cellulose fibres there are two different ways of binding the fibres, viz. an application of glue to the web surfaces and, respectively, an admixing into the fibre charge of heat actuated binding fibres that are actuated by passing the web through a heating zone. The latter method is the better in practice, of course, in particular for liquid absorbing products, but the problem exists that the finished material is dusting with short, unbonded fibres. According to the invention it has been realized that it is possible to widely avoid this problem by auxiliary use of the first method, modified to the effect that both surfaces of the web are concurrently subjected to a supply of a very small amount of glue in foamed condition, e.g. with only 1 gram per square meter, whereby the surfaces remain permeable, but also sealing against extrusion of short fibres from inside the web.

Filed: 1996-08-07
Abstract: A method and apparatus for remote spectrum analysis is disclosed. A channel measurement device is configured to receive and measure the radio spectrum in a geographic location during a measurement phase of operation. A microprocessor processes the signals and stores processed data on a storage device. The channel measurement device contains a communications interface to a land line telephone network and/or a cellular telephone network. During a data transfer phase of operation, the channel measurement device sends the processed data to a remote processor via the land line or cellular telephone network. In addition, the remote processor may act as a remote user interface to control the operation of the channel measurement device. In particular, the remote processor may be used to store values for user programmable configuration parameters in a memory of the channel measurement device via the land line or cellular telephone network. In one embodiment, the cellular telephone network interface may include the components necessary for communicating directly with the cellular telephone network. In another embodiment, the cellular telephone network interface is capable of connecting to a cellular telephone for such communication with the cellular telephone network.

Title: O-ring insert
Inventor: WRIGHT JOHN BENNISON
IPC: F16J15/02
Filed: 1997-01-10
Abstract: The invention relates to an insert for providing a seal at the junction of axially aligned bores extending through two adjacent segments of material. The insert is of a rigid material, has an inner diameter equal to the diameter of the bore, and comprises a retaining portion with a frusto-conical outer surface and a stem portion with a cylindrical outer surface. The insert is retained in a co-axial recess which extends inwardly from the face of one of the segments of material.  In this manner, the retaining portion of the insert and the walls of the recess define a groove for retaining an O-ring. Also described is a method of providing a seal at the junction of axially aligned bores extending through two segments of material.  The method comprises boring a recess in one of the bores, introducing the insert into the recess, retainably inserting an O-ring into an annular groove defined between the insert and the recess, and bringing the segments together. The invention further relates to a method of re-establishing a seal at the junction of axially aligned bores originally provided with a conventional annular O-ring groove, wherein the area between the bore and the inner surface of the annular groove has been destroyed over time due to a corrosive and/or abrasive action of the fluid.

IPC: H02P9/00
Filed: 1997-03-18
Abstract: A single operation detecting apparatus for detecting that a distributed power supply including an induction generator and synchronous generator is switched to single operation from cooperation with another power system.  It includes a frequency detector connected to a line system of a customer, reactive power regulating equipment connected to the output terminal of the induction generator, a fluctuation signal generator for providing periodic small fluctuations to a reactive power setter of the reactive power regulating equipment, and a single operation signal generator for monitoring the output of the frequency detector to output a single operation signal when the monitored output deviates from a range between allowable upper limit and lower limit around a reference frequency.  It is possible to detect the single operation by actively disturbing the balance between the energy generated by the induction generator and synchronous generator and the power consumed by the distributed power supply, when the distributed power supply is disconnected from the cooperation with power system.
