Patent number: 9945379Abstract: An improved discharge port of a rotary screw compressor is described. A discharge port of a screw compressor generally includes a restrictive portion to help prevent a leakage of working fluid back to a suction side of the compressor. The improved discharge port is configured to have a restrictive portion with a reduced size compared to a restrictive portion of a conventional discharge port, resulting in an enlarged opening of the discharge port compared to a conventional discharge port. The improved discharge port can help discharge the compressed working fluid more quickly than a conventional discharge port, reducing and/or avoiding over-compression of the working fluid. The efficiency gained due to the enlargement of the opening may be more than the efficiency loss due to leakage of working fluid back to the suction side, resulting in a net efficiency gain of the compressor.Type: GrantFiled: October 10, 2014Date of Patent: April 17, 2018Assignee: TRANE INTERNATIONAL INC.Inventors: Scott Michael Branch, Gordon Powell, Jr.

Patent number: 7458733Abstract: A method of cooling an optical transceiver that is mountable in a wall opening and a method of cooling a data transfer system in combination with an optical transceiver is described. An optical transceiver is provided that has a form factor and one end portion that is insertable within a wall opening in a wall. Ambient air is ventilated over a major surface portion of the optical transceiver by mounting said end portion to the wall opening so that at least one vent is formed within confines of the wall opening. The vent allows air to pass between the exterior and interior of the enclosure, and over the major surface portion of the optical transceiver.Type: GrantFiled: October 31, 2007Date of Patent: December 2, 2008Assignee: International Business Machines CorporationInventors: William James Anderl, Scott Michael Branch, David Peter Gaio, Michael Francis Hanley, William K.

Patent number: 6916122Abstract: The invention relates to modular heat-dissipating housing covers for opto-electronic modules, e.g. transceivers. The housing covers according to the present invention are constructed out of various different parts, which provide different levels of heat dissipation depending on the desired implementation, while maintaining a seal against EMI leakage. Extra heat sinking portions are provided to dissipate heat generated from specific heat generating sources. The extra heat sinking portions are configured into a shape and/or out of a material that provides more thermal dissipation than the standard cover provided. Independent control over the different heat sinking portions enables a better fit and appropriate dissipation.Type: GrantFiled: February 14, 2003Date of Patent: July 12, 2005Assignee: JDS Uniphase CorporationInventors: Scott Michael Branch, Eugene E.

Patent number: 6916123Abstract: The present invention relates to an optical transceiver unlatching device for disengaging the optical transceiver from a mounting cage found in a host computer device. The unlatching device converts rotational motion from a bail handle into reciprocating motion for a sliding latch member, which disengages spring fingers extending from the mounting cage from abutment surfaces formed in the sides of the optical transceiver. A return spring, extending between the sliding latch member and the optical transceiver housing, is provided to bias the unlatching device into the latched position.Type: GrantFiled: September 8, 2003Date of Patent: July 12, 2005Assignee: JDS Uniphase CorporationInventors: Bruce P.

Patent number: 6890206Abstract: The present invention relates to a latching system for an optical transceiver module that eliminates the use of compound latching mechanisms by providing a single latching lever for unplugging the module from its mounting cage. The latching lever includes a pair of arms with a bail handle on one end to facilitate actuation of the latching lever and manipulation of the module. The other end of the latching lever applies a force to the cage to separate first and second mating latching members on the module and the cage, respectively. The fulcrum of the lever is provided by a bend in each arm, which acts like a journal, mounted in a bearing depression formed in the module housing.Type: GrantFiled: March 4, 2003Date of Patent: May 10, 2005Assignee: JDS Uniphase CorporationInventors: Eugene E.

Patent number: 6788540Abstract: The present invention relates to a cage for holding an optical transceiver module in electrical contact with a host circuit board. The cage includes front, middle and rear sections, and facilitates the insertion of the optical transceiver into the cage, as well as providing electromagnetic shielding and facilitating thermal dissipation. Typically, the cage is for use with an optical transceiver module including an integral heat sink cover or with an optical transceiver module including an external heat sink mounted over top of the cage. Various embodiments illustrate different schemes for maximizing heat dissipation by providing large openings in the middle section of the cage, as well as mounting surfaces on the front and rear sections for mounting external heat sinks. One or more crossbars are provided for guiding the transceiver module during insertion.Type: GrantFiled: January 28, 2003Date of Patent: September 7, 2004Assignee: JDS Uniphase CorporationInventors: Bruce P.

Patent number: 6744639Abstract: An electromagnetic radiation shield useful to attenuate or prevent the escape of electromagnetic radiation from the front of transceiver opto-electronic subassemblies resident in an opening or port in the housing of an electronic system is formed with both an aperture for each barrel of the opto-electronic subassemblies and a plurality of extensions projecting outwardly from the shield. The distal ends of the extensions are bent or shaped to form smoothly curved contact surfaces that project outside the transceiver module to make contact with a grounded member of the housing or other electrically grounded portion of the electronic system of which the transceiver module is a part. The electromagnetic radiation shield is assembled with the transceiver subassemblies and disposed within a transceiver module to be inserted into a communications port of a computer or server. The transceiver module contains elements that may generate and radiate electromagnetic energy.Type: GrantFiled: May 5, 2000Date of Patent: June 1, 2004Assignee: JDS Uniphase CorporationInventors: Scott Michael Branch, David Peter Gaio, Michael Francis Hanley, William K.

Patent number: 6666484Abstract: A push-to-release latching mechanism for retaining a transceiver module in a communication port of a computer or server is provided with a beam spring structure for positional restoration of the latch member, and the latch is supported and moveable relative to the host transceiver module. The latch member may be formed to include camming surfaces that facilitate the insertion of the transceiver module into a communication port and mate with a guide rail and connector resident in a communication port. The latch member may be adapted to latch with a rigid latch bar or a cantilevered spring. Additionally, the latch may be formed with a camming surface which insures that the latch is displaced to a latching position whenever network cables are connected to the transceiver module by camming the latch into the secure, latched position and subsequently preventing the latch from moving to an insecure or unlatched position.Type: GrantFiled: June 9, 2000Date of Patent: December 23, 2003Assignee: JDS Uniphase CorporationInventors: Scott Michael Branch, Leland L.

Patent number: 6648693Abstract: An electrical connector system has two connectors, one of which is included in a module mateable with the other connector in a pluggable manner. The other connector includes a body and two or more electrical contacts. The body of that electrical connector includes a spring that provides a combined lock-down force and kick-out force. The lock-down force biases the module against the other connector, thereby providing a secure electrical and mechanical connection. The kick-out force biases the module away from the other connector to separate or eject the module when a user actuates a release mechanism. The module also includes a slot that engages a projection on the other connector to promote alignment of the mating electrical contacts.Type: GrantFiled: September 8, 1999Date of Patent: November 18, 2003Assignee: International Business Machines CorporationInventors: William K.
