Patent CA-2137181-A1 (CA)
Title: Hot gas manifold system for a dual topping combustor gas turbine system
Inventor: WIANT BENJAMIN CRAIG
IPC: F02C3/20
Filed: 1994-12-02
Abstract: A hot gas manifold system for a gas turbine power plant  utilizing  a  pressurized  fluidized  bed  combustor producing gas that is heated in two topping combustors.  Each topping combustor is connected to a separate manifold.  The manifolds, which are adjacent each other in a forward and aft arrangement, are disposed in the turbine shell between the compressor and turbine sections of the gas turbine and each forms a toroidal chamber that encloses the rotor.  A plurality of ducts extend downstream from each manifold, with the ducts of the forward manifold extending through the aft manifold. Each of the ducts has an arcuate outlet that together form an annular hot gas path that matches the annular inlet to the turbine section.   The ducts  from each manifold  form an alternating array so the hot gas from each of the individual topping combustors is symmetrically distributed around the turbine inlet.

Title: Block with Lateral Spacers
Inventor: SCHEIWILLER RENE
IPC: E01C5/00
Filed: 1994-02-22
Abstract: A paving stone (1) which has lateral spacers (12, 13) for forming uniform joints (22) is proposed. The abutting faces (4) of the spacers (12, 13) are shaped for the positive joining-on of a neighboring stone in a paving stone bond (19) in such a way that, with complementary spacers (12, 13), to be assigned to each other in pairs, of opposite paving stone sides (9, 11), they have the same profile and are shaped such that they join against one another in a positive meshing. This provides a stone which, by the shaping of its spacers, anchors the stone in the bond (19) with respect to a side-parallel displacement.
Patent CA-2140457-A1 (CA)
Inventor: WALKER G KENT
IPC: H04L7/00
Filed: 1995-01-18
Abstract: The apparent accuracy of a clock circuit used to recover timing and transmitted information signals in a data receiver is improved. A timing relationship inherent in a received signal is detected prior to the acquisition of a timing component embedded in a desired information portion of the received signal. The timing relationship has an accuracy that is greater than the accuracy of the clock circuit. The clock circuit is controlled in response to the timing relationship to operate with an improved range of accuracy. Thereafter, the embedded timing component is acquired and used to control the clock circuit. In an illustrated embodiment, the timing relationship is derived from a symbol rate of the received signal. In an alternate embodiment, the timing relationship is obtained from a separate transmitted reference signal, such as a transmitted television signal.

Title: Trellis
Inventor: NEFF GREGOR N
IPC: A01G17/06
Filed: 1995-06-15
Abstract: A trellis and trellis kit are provided with poles and lattice netting in which the lattice netting can be rolled up on the poles to which they are attached.  Two crossbars are provided.  They can be easily slipped on and off the poles to detach them from the netting, and the trellis can be formed into a compact package for shipping, warehousing, or storage by the user in a protected location.

Abstract: An access control system for permitting or denying access to a restricted area includes an access control device capable of reading information stored on an access card and determining whether the information read from the access card corresponds with memory information stored in the access control device to permit or deny access to a restricted area.  A video camera is positioned at the entry area to the restricted area to capture live video images of an individual attempting access.  The access control device determines whether the card is valid or invalid and translates the information into an output having text information through a serial communications interface port or other means of transmitting data to a text overlay control device.  The text overlay control device overlays the text information describing the access control event directly onto the video images received from the video camera.  The text information and video images are displayed on a video monitor while also being recorded on a video cassette recorder for later viewing.
