Patent CA-2163145-A1 (CA)
Title: Skidding grapple
Inventor: BARWISE ROBERT D
IPC: B66C1/58
Filed: 1995-11-17
Abstract: A skidding grapple to move a load such as a tow of logs, over a terrain that is particularly difficult to traverse.   A grapple assembly to engage the load has offset grapple arms that bypass one another when closing to encompass the load.  A choke line is connected at one end to the winch line, and has first and second choke line legs that connect to the ends of the grapple arms.  As the grapple arms close, the choke line legs form a noose to engage the end of the load and bear the weight of the load upon lifting of the grapple arms.  A coupling releasably connects the grapple assembly to the boom.  A winch line extends over the boom end, past the coupling and is connected to the grapple assembly, such that upon release of the grapple assembly from the boom, it remains  connected  to  the  tow  vehicle  by  the  winch  line.          Reconnection of the coupling assemblies is facilitated, since the winch line passes over the boom tip and results in alignment with the coupling assemblies as they come together.

Abstract: This disclosure relates to a reinforced metal stud for use in a hollow wall.  The wall includes sheet metal studs placed horizontally between adjacent, horizontally extending gypsum core boards, typically in the walls surrounding an elevator shaft and stairwells, and in area separation walls and the like.  The metal studs include an inner flange, an outer flange and an adjoining web connecting the flanges, with a core board abutting each side of the web.  Standard or special fire-retardant gypsum wallboards are attached by fasteners to the outer flanges of the metal studs.  A hollow space is thus formed between the core boards and the wallboards, the outer flange and a portion of the web being within the hollow space.  A reinforcement channel is provided for attachment to and strengthening of the stud.  The web and the outer flange of the stud form a partially en-closed space, and the reinforcement channel nests in the enclosed space.  Fasteners secure the channel to the web of the stud, and additional fasteners may secure the wallboard to the outer flange of the stud and to the channel.

Abstract: In a load loss standard for calibrating a power measurement system, a pair of reference voltage signals are generated, one in-phase and the other in quadrature with a test voltage ac source. A transconducting and summing amplifier generates an output current corresponding to the vector sum of these reference signals. By varying the magnitude of each of the reference signals independently of each other it becomes possible to vary the phase of the output current relative to the source, while keeping the magnitude of such current constant.

Abstract: A portable mixer has a bin with a number of augers rotatably mounted therein. The augers have forward flights, for conveying roughage feed material, such as hay, in a forward direction, and reverse flights, for conveying the feed materials in an opposite direction. The augers mix feed material introduced into the bin and convey the feed material to a discharge opening. At least one of the augers has a ribbon flighting positioned at an outer peripheral edge of the auger flighting. The ribbon flighting has an outer edge having a continuous saw-tooth cut. The relatively small, closely spaced teeth of the saw-tooth edge cuts the elongated fibrous material, such as hay, without increasing the torque required by the auger. The ribbon flighting is formed from a number of separate, identical ribbon flighting members positioned in series along the outer peripheral edge of the auger flighting.

Title: Co-channel interference reduction
Inventor: TONG WEN
IPC: H04B1/12
Filed: 1996-10-09
Abstract: Co-channel interference in baseband digital samples of an FM communications (e.g. AMPS) signal is cancelled by a complex signal limiter and non-linear filter (CLNF) (16), to which the samples are supplied, and a time-varying null filter unit (18), to which the output samples from the CLNF are supplied, for separating the desired signal from residual interference. The output samples from the CLNF are also supplied via a selective narrow band filter bank (17) to a non-linear transform unit (19) for producing an energy based demodulation signal from which time-varying coefficients for the null filter are obtained. The units can be used individually or in different arrangements and combinations, and the transform unit can be augmented and used to replace a conventional FM demodulator (14).

IPC: F04D5/00
Filed: 1996-12-31
Abstract: A regenerative or toric pump adds energy to a fluid using an impeller having an axis of rotation and axially spaced, radially extending first and second surfaces.  A casing encloses the impeller and has a fluid inlet and a fluid outlet separated by a stripper.  The casing has axially spaced, radially extending first and second sidewalls facing the first and second surfaces of the impeller respectively.  Axially and radially extending blades or vanes are formed on an outer radial periphery of the impeller for driving fluid from the inlet toward the outlet as the impeller rotates about the axis of rotation.  A fixed surface is formed in at least one sidewall of the casing for directing fluid back toward the impeller.  Improved operating characteristics and extended range are accomplished through modification to the vane configuration of the impeller and/or by modification of the side channel configuration of the pump chamber in an asymmetrical fashion.  The vanes can be modified to include a radially inward based portion extending in a generally trailing direction with respect to rotation of the impeller and a radially outward tip portion extending in a generally leading direction.  The blades may also include a chamfered surface on the trailing edge of the base portion.  The impeller chamber can be modified separately by expanding a side channel in the casing, or by insertion of a spacer between the side channel and the remaining portion of the casing defining the impeller chamber.
