Publication number: 20230349385Abstract: A rotating machine for delivering a working fluid to a system includes a compressor housing defining a compressor housing interior and partially defining a flow path. The rotating machine also includes a shaft and a compressor wheel disposed in the compressor housing interior. The rotating machine additionally includes a backplate coupled to the compressor housing and further defining the flow path. The backplate and the compressor housing are configured to direct working fluid from the compressor housing interior through the flow path. The backplate defines a working fluid connection adjacent the compressor wheel and/or the flow path such that the working fluid connection is fluidly coupled to the flow path and such that the compressor wheel delivers working fluid from the compressor housing interior and the working fluid connection to the flow path.Type: ApplicationFiled: April 21, 2023Publication date: November 2, 2023Inventors: John Robert ZAGONE, Robert Malcolm WALLACE, Kevin John FOGARTY, Samuel Whitney WELDON

Patent number: 11242183Abstract: The present disclosure describes speech or sound-emulating bottle cap apparatuses and systems and methods for manufacture thereof. It will be understood that a bottle cap prohibits gases from escaping a pressurized bottle. Ordinarily, when the cap is removed from the bottle, the escaping gas will emit a sound, but the sound carries no discernable meaning, cognizable message or recognizable sound (aside from gas simply escaping a pressurized container). Embodiments described herein harness gas escaping from a bottle (when the cap is removed) to generate a discernable meaning, cognizable message or otherwise recognizable sound. The sound-chamber may be wrapped or twisted into a coil or helix shape (in addition or as an alternative to miniaturizing it). A coil or helix shape permits recovery of the original sound quality of the initially modeled sound-chamber, resulting in “a sound-emitting cap-chamber” removably or permanently coupled to a bottle cap or bottle as described herein.Type: GrantFiled: August 3, 2018Date of Patent: February 8, 2022Assignee: Twist 'N' ShoutInventor: Malcolm Wallace Hatton

Patent number: 10947931Abstract: A product may include a bearing housing in which a shaft may be supported by a bearing so that it may rotate. A compressor wheel may be disposed on the shaft. A compressor cover may be connected with the bearing housing, which may form a compressor body and may define a chamber within which the compressor wheel may rotate. A diffuser may extend radially outward from the chamber and may receive gas from the compressor wheel. An inlet may be provided to the compressor body, which may receive a supply of exhaust gas. An EGR distribution cavity may be defined within the compressor body and may extend around the shaft. An EGR inlet channel may extend into the bearing housing from the inlet to the EGR distribution cavity. An EGR passage may extend from the EGR distribution cavity to the diffuser.Type: GrantFiled: October 12, 2018Date of Patent: March 16, 2021Assignee: BorgWarner Inc.Inventors: Joseph Powell McHenry, Gordon Clark Jenks, Robert Malcolm Wallace

Publication number: 20030185212Abstract: TDM (time division multiplexed) traffic is transported together with a TDM performance monitoring channel over a ATM (asynchronous transfer mode) network. The TDM traffic is segmented at ingress to the ATM network and is packed as payload data into ATM cells. Each cell payload is provided with an AAL1 segmentation and reassembly protocol data unit (SAR-PDU) containing a channel state information (CIS) field, a sequence number field, and a sequence number protection field. A performance monitoring channel is provided by utilising spare bits in the CIS field in alternate cells. On egress from the ATM network, the sequence number protection and performance monitoring data provide a means of identifying both missing and corrupted cells so as to determine a measure of the quality of transport of the TDM traffic over the ATM network. The measured transmission quality may be compared with service levels defined in a service level agreement.Type: ApplicationFiled: March 29, 2002Publication date: October 2, 2003Inventors: Michael Kelly, Malcolm Wallace, Marija Spasic, Robert Roust

Patent number: 6252887Abstract: A method and apparatus is disclosed for providing an interworking function to interface a frame relay LAN to an ATM network. Data from a broadband packet switched data data communications network which uses data packets of a fixed size is transferred to a narrow-band packet switched network which uses data packets of variable size by queuing input fixed length data packets data packets of variable size; processing the data payloads of said input data packets received from said queue to line-encode said data so it may be transmitted in said data packets of variable size; and generating output fixed length data packets of the same size as the input fixed-length data packets for transmitting said processed data payloads to a fixed-length to variable lengh data packets conversion device.Type: GrantFiled: January 28, 1998Date of Patent: June 26, 2001Assignee: Northern Telecom LimitedInventor: Malcolm Wallace
