  • Patent number: 9169847
    Abstract: Radial magnetic bearings (125) of a centrifugal gas compressor (100) may lose power and fail to support the shaft (120) resulting in damage to the shaft (120). Auxiliary bearings (135) may be used to support the shaft (120) during such a failure. A landing guard (140) may be installed as a sacrificial piece between the shaft (120) and the auxiliary bearings (135). Landing guard (140) includes slots (144) that may be used with pins (121) in the shaft (120) to prevent an angular displacement between the landing guard (140) and the shaft (120).

  • Patent number: 9127664
    Abstract: A method of manufacturing a plurality of housings. The method may include maintaining an inventory of initial products. Each of the initial products may include a central hollow body extending along a longitudinal axis and monolithically formed with at least one of a suction passage and a discharge passage. Each of the products may have a same initial length. The method may further include receiving a first order for a first housing having a first length and machining a first product to the first length to form the first housing. Also, the method may include receiving a second order for a second housing having a second length and machining a second product to the second length to form the second housing. The first length and the second length may be different.

  • Publication number: 20150012319
    Abstract: An employee location noticeboard is in the form of a dry-erase board, with a list of prepared options and checkboxes providing specific details about the employee's current location and estimated time of return. The noticeboard also provides some options that are not intended to be actually used, but instead may provide harmless amusement for the reader. A method of producing noticeboard content provides for determining legitimate reasons for an employee to be away from his or her desk, determining not legitimate but humorous reasons for the employee to be away, and printing the list on the noticeboard. The noticeboard features suction cups for easy mounting on an office door.

  • Publication number: 20140112773
    Abstract: A shaft (120) configured to be mounted within a centrifugal gas compressor (100) includes a suction end (116), a discharge end (117), and a shaft surface. The shaft surface includes a hardened surface (123) located between the suction end (116) and the discharge end (117). The hardened surface (123) is a localized portion of the shaft surface having a different surface treatment than a remainder of the shaft surface. The hardened surface (123) is harder than the remainder of the shaft surface. The hardened surface (123) is configured to axially align with a central auxiliary bearing (137).
