Patent CA-2084932-A1 (CA)
IPC: B61G5/02
Filed: 1992-12-09
Abstract: The present invention relates to a railway car coupler arrangement whereby a standard yoke, follower, and draft gear are removed from the center sill and replaced with a short yoke member, a spacer block member and slackless drawbar arrangement, namely, a pocket casting wedge shim, and follower, easily converting the coupler arrangement to a drawbar arrangement without modifying the center sill.  The short yoke member, spacer block and slackless arrangement fit exactly within the space formerly occupied by the draft gear pocket casting.  The drawbar arrangement maintains the same degrees of angling freedom as the coupler since the drawbar is connected and pivoted from the same pin location as when the coupler was installed.  The short yoke member is also designed to more uniformly distribute draft loads to the center sill by transferring forces from the connecting pin into the short yoke member, which in turn transfers those forces into abutting center sill front stops, left intact from the coupler arrangement.  The present invention further provides a quick method for converting a broken coupler to a drawbar arrangement for towing hack to a repair shop.

Abstract: The present invention is directed to a novel converter for interposition between an AC power source and a DC load capable of maintaining a substantially unity power factor independent of the impedance of the load.          According to the invention, the converter has rectifying circuit means to provide DC power to a DC power output circuit from an AC source, means for varying the impedance seen by the AC source in the DC output circuit, and means responsive to a shift in AC input current away from an in-phase relation with the voltage of the AC source under loading of the DC power output circuit for controlling said impedance varying means in a direction to return the AC current towards in-phase relation with the AC voltage.          More particularly, according to the preferred form of the invention, the means for varying the impedance seen by the AC source in the DC output circuit includes a resonant circuit interposed between the rectifying circuit means and the DC output circuit and connected to deliver DC power thereto.  The converter includes a control circuit responsive to the DC voltage of the DC output circuit and the phase between the AC voltage and AC current.  The control converter also includes a variable impedance responsive to the resonant circuit current for controlling the phase angle between the resonant circuit current and voltage across the resonant circuit.

Inventor: ZHAO GUOQUAN
IPC: F24F1/02
Filed: 1993-12-09
Abstract: A low profile room air conditioner. The low profile is achieved in part by the arrangement of components in its outside section. The fan that moves air through the outside section is of the axial flow type mounted so that its axis of rotation is substan-tially perpendicular to the base of the enclosure and so that the fan draws air into the outside section through the top of the enclosure. Air discharges from the outside section through an air discharge on a side of the enclosure. Louvers at the air discharge direct the air exiting the enclosure away from the air inlet. A slinger directs droplets of condensate drained from the inside refrigerant-to-air heat exchanger into the air flowing through the outside section. The air carries the condensate on to the outside refrigerant-to-air heat exchanger where it evaporates. The air flow carries the resultant water vapor out of the outside section.

Abstract: A method and an apparatus align and attach a leadless surface mount component (402) including a termination at each end of the component (402). The termination has bottom (704) and end (702) portions for attaching to a corresponding pad on a substrate (102) by a reflow solder process (1200). A pad arrangement (100) is formed including two opposite pads (108), each pad (108) occupying a tri-oval-shaped area. The tri-oval-shaped area includes an elliptical area (110) substantially centered under the bottom portion (704) of the corresponding termination of the component (402) when the component (402) is aligned with the pad arrangement (100), and an arcuate area (112) contiguous with the elliptical area (110) and extending towards the opposite pad (108) in a central lengthwise direction. A solder paste (202) is applied to the elliptical area (110), and thereafter reflowed, whereby solder (302) in the solder paste (202) liquefies and flows onto the arcuate area (112), thereby facilitating alignment of the component (402) with the pad arrangement (100).
