Title: Automatic shaft ground conditioner
Inventor: TWERDOCHLIB MICHAEL
IPC: G08B21/00
Filed: 1992-08-20
Abstract: 56,890 ABSTRACT OF THE DISCLOSURE         Apparatus for   automatically  cleaning  shaft grounding  devices  in  rotating  machinery  to  reduce or eliminate the  need for on-line servicing of the grounding devices.   When  a  monitoring  system  for  the grounding devices  signals  that  an  excessive electrical charge is present on the shaft, a cleansing  material is  sprayed at the interface  of the  grounding device  with the shaft to remove  any  contaminants  for  the  electrical insulating material between  the bearings and the rotating shaft, and to  re-establish  the  grounding  path  from   the  shaft. Voltage discharge  form the  shaft to the bearings through the bearing lubricating oil  is thereby  prevented.  Alarm delay  of  the  shaft  ground monitoring device allows the apparatus to function  automatically,  obviating  the need for  on-servicing  by  plant personnel or unnecessary shut down of the machinery.

Title: Compensation mechanism for a pressure sensor
Inventor: KEMP STEPHEN J
IPC: G01L7/08
Filed: 1992-12-30
Abstract: A differential pressure sensor with a compensation means, said differential pressure sensor comprising the diaphragm with a first means having a mass mounted upon the diaphragm. The first means is utilized to determine the position of the diaphragm relative to an initial first position and/or to increase the effective area of the diaphragm. A housing contains the diaphragm, the housing has a first and a second inlet port. The first inlet port provides a first pressure to a first side of the diaphragm and the second inlet provides a second pressure to the second side of the diaphragm, the diaphragm moving to the lesser of the two pressures. A counterweight mechanism is located in the housing having a inner arm and an outer arm. The counterweight mechanism pivots about an axis. The center of gravity of the counterweight mechanism is located on the outer arm. The inner arm is in contact with the first means, whereby the counterweight mechanism compensates for the mass added to the diaphragm which enables the pressure sensor to be mounted in any orientation.

Patent CA-2090159-A1 (CA)
Inventor: JOHNSTON JAMES D
IPC: G10L21/003
Filed: 1993-02-23
Abstract: Coding of high quality stereophonic audio signals is accomplished in a perceptual filterbank coder which exploits the interchannel redundancies and psychoacoustic. Using perceptual principles, switching between a normal and short window of input samples improve output signal quality for certain input signals,particularly those having a rapid attack. Switching is also accomplished betweencoding of left and right channels and so- called sum and difference channels in response to particular signal conditions. A number of new perceptually based techniques, including improved threshold determinations, result in high quality.

Title: Aluminum alloy sheet with improved formability and method of production
Inventor: UESUGI YASUJI
IPC: C23C2/28
Filed: 1992-07-22
Abstract: The invention provides an aluminum alloy sheet having improved formability, an elongation of at least 30%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising an aluminum alloy substrate containing at least 4 wt% of Mg and a Fe rich plating layer on a surface thereof in a coating weight of 1 to 50 g/m2.      Also provided is a bake hardenable, surface treated aluminum alloy sheet having improved formability, an elongation of at least 25%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising a bake hardenable aluminum alloy substrate containing Mg and Si in an amount of at least 0.4 wt% calculated as Mg2Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m2.      By forming a zincate layer as an undercoat below the Fe rich plating layer, the plating adhesion is further improved.      The preferred Fe rich plating layer is a Fe-Zn alloy plating layer containing 20 to 80 wt% of Zn for corrosion resistance improvement. A Fe-Zn alloy plating layer containing 30 to 40 wt% of Zn meets both formability and corrosion resistance.     By further forming a layer of an inorganic compound such as alkali metal borate on the Fe plating layer, sliding frictional behavior is further improved.      The preparation of a bake hardenable, surface treated aluminum alloy sheet includes annealing at a temperature of at least 480°C before or after Fe rich plating.

Title: Spindle retainer for axle housing
Inventor: BABCOCK KEITH A
IPC: B60B35/04
Filed: 1993-07-07
Abstract: ABSTRACT OF THE DISCLOSURE A structure for positively retaining a journal portion of a spindle in a tube portion of a vehicle axle housing includes a transverse aperture formed through the tube portion near the outer end thereof.  The aperture extends partially into the interior of the tube portion and is defined by a radius of curvature.  A generally hollow cylindrical spindle is connected to the end of the tube portion.  The spindle includes a journal portion which is telescopically received within the hollow tube portion.  An annular groove is formed in the outer surface of the journal portion of the spindle near the inner end thereof. The groove is defined by a radius of curvature which is substantially larger than the radius of curvature defining the transverse aperture.  When the spindle is inserted within the tube portion, the groove is aligned with the transverse aperture.  A threaded fastener is disposed within the transverse aperture.  The threaded fastener has a radius of curvature which is slightly smaller than the radius of curvature of the transverse aperture.  The threaded fastener prevents the removal of the journal portion from the tube portion, thereby positively retaining the spindle within the axle housing.

Patent CA-2106276-A1 (CA)
Inventor: STRIETER JOHN R
IPC: E01F9/619
Filed: 1993-09-15
Abstract: This invention describes the design and method of installation of wild animal highway warning reflectors. The reflector consists of a transparent plate having a flat light entrance surface and a backside reflection surface from which the reflected light is dispersed. The rear surface is comprised of many reflecting toric surfaces arranged vertically and horizontally side-by-side. The new design of the toric surfaces and the unique method of installing the reflectors provide complete reflected light coverage for all variations of roadside terrain to warn wild animals that wish to cross a highway at night. To an animal each reflector glitters with colored light. As a vehicle passes, animals see an unnatural, sequence of lights coming from a plurality of reflectors located along both sides of the highway. Installation of these warning reflectors adjacent to highways where wild animals frequently cross has led to a considerable reduction of the number of accidents.

IPC: B01D24/00
Filed: 1992-04-09
Abstract: Devices (10), such as filters, catalytic converters and the like, for separating selected substances from a stream of fluid. The device is made of continuums (23A, 24A, 31, 32, 33, ...) made of filter material and arranged so that substantially all of the fluid passing through the filter must pass through the separation material. In one embodiment the continuums, typically textile yarn, are arranged parallel to each other in planar arrays, such arrays are then superimposed to form a laminated grouping with each continuums in each array angularly oriented with respect to and in contact with continuums in each adjacent array. Two distinct patterns of internal distribution paths for the fluid being processed are thereby formed by spacing between continuums, In preferred embodiment, the constituent continuums in each array cross those in each next adjacent array channels formed by the aggregations of crossovers substantially at right angles to the plane of array and/or intra-array channels, that translaminar channels provide substantially straight channels that are at right angles to the planes of the arrays. Some translaminar channels are adapted for use as inlets (X) and others as egress (O) channels.
