Patent number: 11001973Abstract: A gauge spacing apparatus for positioning pot sleepers with respect to existing sleepers of a railway track has a pair of turnout rails, which are separated from one another by a desired gauge distance. The gauge spacing apparatus includes a first guide member aligned with and secured with respect to a portion of the existing rail; and a second guide member angled with respect to the first guide member at a turnout angle. The second guide member is aligned with a portion of a turnout rail to allow the turnout rail to be provided with supporting pot sleepers, such that the desired gauge between the turnout rails is maintained. Also provided are a rectangular gauge spacing apparatus, a shear plate arrangement for providing supported engagement between first and second sections of rail, and a support framework for supporting a planar supporting member spanning over an existing rail.Type: GrantFiled: July 8, 2016Date of Patent: May 11, 2021Assignee: Non Intrusive Crossover System LimitedInventors: Roy Anderson, Donald McCallum, Henry Maxwell

Patent number: 10157084Abstract: A system for managing the provisioning of cloud based services includes a collection module, a configuration module, a licensing module and a set up module. The collection module automatically obtains and stores information from end user machines that relevant to the provisioning of the could-based services. The configuration module uses the obtained information to automatically configure the use of the cloud based services. The licensing module automatically configures the account and licensing information allowing an end-user machine to access the cloud based services. The setup module automatically configures the end user machines to access and use the cloud-based services.Type: GrantFiled: September 29, 2016Date of Patent: December 18, 2018Assignee: ConnectWise, Inc.Inventors: Matthew Nachtrab, Donald McCallum, Anthony J.

Patent number: 10116619Abstract: Systems and methods of the present disclosure facilitate provisioning an out-of-band system. In some embodiments, the system includes a server of a first domain, which includes a management engine. The management engine can establish a network tunnel with a device on a second domain, and modify the domain on a DHCP server on the second domain to be the first domain. The device can use a fixed subdomain of the first domain to transmit a provisioning request for an OOB management system to a provisioning engine in the first domain, which can transmit a certificate including the first domain to the device. The device can validate the certificate by comparing the domain in the certificate to the domain from the DHCP server and verify that they match. The management engine can modify the DHCP server to have the original second domain.Type: GrantFiled: March 18, 2015Date of Patent: October 30, 2018Assignee: Connectwise, Inc.Inventors: Donald McCallum, Brett Alan Cheloff, Kevin Davis

Publication number: 20100218927Abstract: A heating surface element with a zig zag arrangement of longitudinal undulations which serve to minimize the skew flow of the gas. The angle of the undulations is preferably 15° to 35° to the primary flow direction of the gas. When used in combination with a notched heat surface element, the undulation preferably crosses no more than one opposing notch before changing direction.Type: ApplicationFiled: July 31, 2006Publication date: September 2, 2010Inventors: Jim Cooper, Donald McCallum

Patent number: 7604205Abstract: A turnout for a railway track having a raised track surface to provide a path along which the wheels of a train can travel from one railway track to another. The raised track surface is of a sufficient height such that the wheels of the train are arranged to clear each railway track being crossed. The turnout facilitates Single Line Working on a second railway track to clear a first railway track for maintenance or other purposes. Pot sleepers for supporting rails of a railway track and a method of installing them is also provided.Type: GrantFiled: August 14, 2003Date of Patent: October 20, 2009Assignee: Scott-Track LimitedInventor: Donald McCallum

Publication number: 20090084862Abstract: A system for selecting digital content from at least one content source employs a plurality of RFID enabled objects that are read by one or more RFID readers. The RFID enabled objects may be, for example, RFID enabled media objects or RFID enabled non-media objects, such as any suitable RFID enabled object. Specific combinations of RFID tags and RFID enabled objects, or RFID enabled media objects provide access to more (or different) digital content than the same tags provide alone. A method includes contactlessly reading a plurality of RFID tags associated with a plurality of RFID enabled objects to obtain a plurality of RFID tag information and determining whether each of the read plurality of RFID tag information has been read within a suitable time period with respect to each other. If so, the method includes sending the read plurality of RFID tag information for receipt by a content delivery authorization unit to determine if downloadable content is available for download.Type: ApplicationFiled: February 25, 2005Publication date: April 2, 2009Inventor: Donald McCallum

Patent number: 5443113Abstract: A Ljungstrom type heat exchanger in which the bottom sector plate is provided with welded sector plate ribs which are welded to ribs secured to the frame of the heat exchanger. The upper surface may be curved to be complementary to the thermally induced curvature of the rotor. The fairings associated with the support for the upper sector plate may be provided with ports for the passage of some hot gases to prevent distortion of the main beam. A cleaning device is disclosed in which a feed pipe is fully retractable having a nozzle at its radially outer end.Type: GrantFiled: November 23, 1993Date of Patent: August 22, 1995Assignee: Howden Group PLCInventors: Ronald Mulholland, Donald McCallum
