Abstract: In general, the present invention discloses a landscape edging device for dividing distinct landscaping areas, comprising: a vertical barrier; a top portion disposed at the top of and integral to the vertical barrier; and an anchoring portion at the bottom and integral to the vertical barrier, wherein the anchoring portion in turn comprises: an offset channel formed from the vertical body and disposed on one side of the vertical body, wherein the offset channel comprises a first leg and a second leg; and an anchoring blade disposed on a second side of the vertical body and protruding from the intersection of the first leg and second leg.

Abstract: A logical services loopback framework for establishing transparent loopback connections and associations across Layer-2 networks is provided. The loopback framework operates as a termination/processing point for Transport, Connectivity and Services OAM flows. As a termination/processing point, the disclosed loopback framework realizes connections and associations that are used to transparently test and monitor various layers, such as OSI-specified protocol layers, policy-enabled layers, and/or business-oriented layers.

Abstract: A network interface card and system incorporating the interface card with hardware link failure detect circuitry and operating system compliant driver and GUI management software and system operator selectable delay, to provide soft fail-over transfer from the primary to a secondary network link port without data loss. The systems comprising the multi-port interface card according to the present invention provide a single network and redundant paths with optional conversion to different data medium, e.g. between fiber optic and twisted pair, and also comprises multi-network configurations connecting common equipment having the multi-port interface card according to the present invention therein.

Abstract: A scroll member for scroll compressor contains a phenol aralkyl resin and a glass fiber and has feature that the dimensional change rate of the member is 0.05% or below under a chemical stability test condition conducted in an atmosphere in which a refrigerant and a refrigerating machine oil coexist at a high temperature and a high pressure, thereby making the resin scroll member practical and chemically stable. The scroll member may further contain a phenol resin and/or glass beads. The scroll member may be formed by a heat treatment having stepwise temperature increase of a molded material from an initial temperature range of 120 to 140° C. to a final temperature range of 170 to 177° C. The heat treatment can be implemented sequentially, e.g., for four hours or more at a temperature range of 120 to 140° C., for four hours or more at a temperature range of 140 to 170° C., and for four hours or more at a temperature range of 170 to 177° C.

Abstract: A submarine boat of the engineless type wherein the propulsion and vertical displacement thereof are distinctively obtained by cooperatively changing the longitudinal angle of inclination or pitch attitude and the buoyancy thereof. This submarine boat includes an elongated shell having apertures allowing water in and out thereof, an air-tight cabin, a pair of bellows extending lengthwise longitudinally of the shell and each having an open end communicating with the cabin, hydraulic cylinders extending into the bellows and connected to the other end of the latter respectively, and separate two-way valves connected to the hydraulic cylinders respectively to selectively actuate the latter, thereby producing selective expansion or contraction of the bellows.
