Title: Geometry board
Inventor: STEVENS GEORGE R
IPC: G09B23/04
Filed: 1994-02-03
Abstract: A geometry board having pegs arranged on its top face for the demonstration of planar geometric figures by stretching of elastic bands about the pegs. The disclosed board is of clear injection-molded plastic and has a square face with the pegs arranged in a grid on the face including along edges of the board. Pegs along the edges are in the shape of semi-cylinders and the arrangement is such that a pair of boards may be located side-by-side so that the semi-cylinders are paired up so that each pair of semi-cylinders forms a single cylinder. Pegs located at the corners of the board are in the shape of quarter-cylinders so that when four corner pegs are located at the center of four boards laid side-by-side the four quarter-cylinders form a singe cylinder. When four boards are assembled together a Cartesian coordinate system is obtain with x- and y-axes along adjacent edges of the boards and point (0,0) located at the intersection of all four boards. All four edges of the board have downwardly depending walls which are crenelated so as to be capable of accommodating edge pegs of an underlying board when boards are stacked one upon the other.      Further, pairs of opposite walls extend outwardly and upwardly so as to form an upwardly open trough, which trough receives one of the downwardly depending walls of another board when the boards are assembled in side-by-side relationship so as to hold the boards together.

Inventor: LIECHTY DERYLL L
IPC: B23P19/08
Filed: 1994-07-25
Abstract: Apparatus and method for assembling a piston ring in a circumferential groove of a piston wherein a plurality of ring nest members are disposed about a common axis for radial movement toward or away from the axis between radially contracted positions and radially expanded positions. The nest members collectively form a circular opening concentric with the axis and a ring-receiving recess concentric about the opening when they are in the contracted positions. The recess locates a radially unexpanded ring concentric with the axis and has a fixed axial dimension for preventing "oil canning" of the ring when it is expanded. The ring nest members are movable from the radially contracted to the expanded positions when the ring is expanded so as to collectively enlarge the opening for receiving the piston and the recess to maintain the expanded ring substantially concentric with the axis while the fixed axial dimension prevents "oil canning". A plurality of radially and axially movable ring expanding fingers are disposed about the axis and positionable in the opening for radially expanding the ring while it resides in the recess. Expansion of the ring effects movement of the ring nest members radially outward to the expanded positions to collectively enlarge the opening. The piston is moved into the enlarged opening along the axis in a manner that the ring expander fingers are moved axially out of engagement with the expanded ring in the enlarged recess while the piston groove is moved to receive the expanded ring from the recess.

Filed: 1994-10-13
Abstract: Abstract Of The Disclosure A roof structure which has a plurality of concrete tiles arranged in overlapping rows on a roof support structure is provided with at least one roof ventilation device for venting the underside of the roof support structure.  The roof ventilation device receives and integrates with a plurality of shortened tiles in an upper row to provide the roof ventilation without disturbing the appearance and continuity of the roof structure.  A hollow upper portion of the roof ventilation device which is generally continuous with the tiles in the upper row forms part of a ventilation path which extends from outside the roof structure to one or more apertures in the roof support structure. At the same time, the hollow upper portion has a plurality of baffles disposed therein for preventing entry of rain water from the outside.  A length of mesh mounted within an inside portion of the roof ventilation device at the back of the upper portion prevents entry of insects, vermin and debris, while foam strips mounted on the mesh seal the space above tiles in a lower row.  A rear portion of the roof ventilation device, which receives the lower edges of the upper row of tiles against foam strips mounted thereon, includes clips for engaging the side edges of such tiles to hold the lower portions thereof in place. A plurality of spaced apart legs extend downwardly from the rear portion into contact with the roof support structure, and extend forwardly into contact with the upper edges of a lower row of tiles.  A separate venting aperture in the roof support structure below each of the tiles in the upper row has a moisture frame mounted therein with a collar extending above the roof support structure to prevent water on the roof support structure from flowing into the aperture.

Title: Method for testing reflection discontinuities in optical waveguides
Inventor: PARKS THOMAS W
IPC: G01M11/02
Filed: 1994-04-15
Abstract: Abstract of the Disclosure A method for detecting reflection-type discontinuities in an optical waveguide fiber, such as those produced by a fiber break, a contaminant in the glass making up the fiber, a microbend, or a mechanical splice or connector, is provided.  The method employs an optical time domain reflectometer OTDR) and involves cross-correlating an OTDR trace or a modified OTDR trace, e.g., one from which fiber attenuation has been subtracted, with a predetermined waveform which is characteristic of a reflection-type discontinuity.  The predetermined waveform can compensate for differences between the noise spectrum of the OTDR trace and white noise.  In particular, a predetermined waveform obtained by backward differencing and then forwarding differencing an average of waveforms known to correspond to reflection-type discontinuities is able to provide such white noise compensation.

Patent CA-2126888-A1 (CA)
Inventor: HAWTHORNE V TERREY
IPC: B61F5/52
Filed: 1994-06-28
Abstract: The sideframe of a railway car truck are constructed such that basic overall sideframe appearance is maintained, but the actual construction results in a more efficient use of the materials as a means of reducing the sideframe weight. This means that material is used according to how the stresses are encountered by the sideframe, dictating that the sideframe midsection is structurally heavier than the sideframe ends. Maximization of this construction is provided by shaping the entire sideframe into a solid, unitary cross-sectional ?-beam shape. A solid top flange of the ?-beam corresponds to the typical top compression member while the solid bottom flange corresponds to the typical bottom compression member. The solid vertical web, which interconnects the top and bottom flanges is a typical, thereby allowing the web to absorb forces which would normally have to be absorbed by either top or bottom member. This feature allows the sideframe to be lighter, yet structurally stronger because the top and bottom members can now be cast dimensionally smaller. To take advantage of the weight savings even further, the ?-beam shape has a structurally tapering thickness from the midsection to the ends and this corresponds to the loading experienced by the sideframe. The open, ?-beam exterior allows for easier and more reliable inspection, as well as improved casting quality due to a substantial reduction in casting core usage.

Title: Alternator rotor and manufacturing method thereof
Inventor: OTAKA HIDEKI
IPC: H02K15/02
Filed: 1994-11-01
Abstract: ABSTRACT         This invention relates to an alternator rotor and its manufacturing method, said rotor having a first rotor member on which a plurality of teeth have been formed, plus a second rotor member arranged so that its teeth are positioned in the spaces in the cylindrical surface formed by the teeth of said first rotor member.  A cylindrically-shaped magnetic material is cut to match the shape of the teeth and is separated into a first rotor member and a second rotor member.  A plurality of teeth is formed on the first rotor member, and teeth are formed on the second rotor member so that they are positioned in the spaces in the cylindrical surface formed by the teeth of the first rotor member.          The two rotor members are mechanically joined by laying each of two rings across the tips of the teeth of one rotor member and across the bases of the teeth of the other rotor member.  Given this construction and method of manufacture, rotors can be manufactured in fewer manhours, electrical efficiency can be improved by increasing the number of poles, and the incidence of defective products is decreased, which means that manufacturing yield can be increased.  In addition, because the fabrication of the teeth can be automated and the welding can be performed easily from the outside, fabrication precision can be increased and quality stabilized.
