Patent number: 12014186Abstract: In an example embodiment, a solution is provided that reduces downtime during operating system patching. This reduces the downtime, regardless of which activity is being performed, and is platform-agnostic. More specifically, a target image for the operating system is obtained. During a preparation phase, a virtual machine with the target image is deployed. This virtual machine is deemed a reference virtual machine. A backup of the reference virtual machine bootable root disk is then taken, and a reference root block device is updated with a customer virtual machine operating system/application/database configuration files and folders. These customer-specific configuration files are then copied from block devices of the customer virtual machine to the reference virtual machine. The reference virtual machine can then be powered on. Only then is the customer virtual machine shut down, and the reference virtual machine swapped in for the customer virtual machine, minimizing the downtime during this period.Type: GrantFiled: March 25, 2022Date of Patent: June 18, 2024Assignee: SAP SEInventors: Siju Thondiyil Vasudevan Nair, Subeesh Nikarthil Sivadasan, Tobias Zeuch, Ritesh Mangalore Shenoy, Gautham Jayatheertha

Patent number: 7618338Abstract: A composite automotive pulley wheel and pump comprises a pulley wheel (2) and a pump (22). The pump comprises an impeller (20) carried on a rotary shaft (6), an inlet region (24) and an outlet region (26). The pulley is mounted on the shaft (6) and comprises a radially outwardly extending support (4) connected to an annular axially extending flange (10, 12), the outer surface of which is adapted to be engaged by a pulley belt. The flange (4) defines a cooling fluid passage (14) within it which extends in the circumferential direction and communicates at two circumferentially spaced positions with an inlet passage (16) and an outlet passage (18), respectively. The inlet and outlet passages (16, 18) extend through the support (4) and the shaft (6) and communicate with the outlet region (26) and the inlet region (24), respectively.Type: GrantFiled: June 11, 2003Date of Patent: November 17, 2009Assignee: Ricardo UK LimitedInventor: David Gareth Greenwood

Patent number: 7611660Abstract: The present invention relates to an apparatus and method for cooling material during continuous vacuum forming. The apparatus includes one or more cooling regions positioned adjacent one or more vacuum regions. A rotatable support belt including perforations therein supports a flexible patterned belt. The flexible patterned belt includes apertures spaced along the length and width thereof. The one or more cooling regions provide a cooling fluid to be drawn through the apertures in the flexible patterned belt to form an area of cooling fluid on the flexible patterned belt which contacts a bottom surface of a hot material received on the flexible patterned belt in order to cool the bottom surface of the material and the flexible patterned belt. The vacuum regions are in fluid flow communication with the perforations of the support belt and the apertures of the flexible patterned belt for drawing the material onto the flexible patterned belt.Type: GrantFiled: July 18, 2006Date of Patent: November 3, 2009Assignee: Bosler Design Services, Inc.Inventor: Kenneth D.

Patent number: 7427248Abstract: Cooling efficiency of cooling air is enhanced and durability of a continuously variable transmission is improved. The continuously variable transmission to be mounted on a vehicle has a transmission case. A primary pulley driven by an engine and a primary pulley linked to drive wheels are rotatably accommodated in the transmission case. A V-belt is provided to extend for winging between the primary pulley and the secondary pulley, and the rotation of the primary pulley is continuously changed and transmitted to the secondary pulley. Fan blades are formed in the primary pulley, and a scroll surface is formed in transmission case from an intake region of the cooling air toward a discharge region thereof so as to gradually away from top faces of the fan blades in a radial-outer direction. Thereby, blowing efficiency of the cooling air can be enhanced and an interior of the transmission case can be sufficiently cooled, whereby the durability of the V-belt can be enhanced.Type: GrantFiled: April 16, 2004Date of Patent: September 23, 2008Assignee: Fuji Jukogyo Kabushiki KaishaInventor: Mitsugi Chonan

Patent number: 7070527Abstract: The invention provides an apparatus and method for cooling a V-belt in a clutch assembly of a CVT. As previously mentioned, the CVT is comprised of a drive clutch assembly, a driven clutch assembly, and an endless V-belt disposed about the drive and driven clutch assemblies. The invention will cool the V-belt as it rides about the drive clutch and driven clutch assemblies. In addition, the invention provides a method for providing a reduced-slip sheave surface for the V-belt in a clutch assembly of a CVT. Normally, as the V-belt rides about the drive and driven clutch assemblies, the V-belt contacts inner surfaces of the clutch assemblies. The invention will reduce belt slippage across the inner surfaces of the clutch assemblies.Type: GrantFiled: December 23, 2002Date of Patent: July 4, 2006Assignee: Polaris Industries Inc.Inventor: Darin Saagge
