Patent CA-2024991-A1 (CA)
Inventor: DETZEL ROGER A
IPC: F16L27/00
Filed: 1990-09-10
Abstract: ABSTRACT OF THE INVENTION    This  invention pertains to  a segmented  insert  installed within the horizontal conduit of a non-mechanical means (such as an L-valve)  for controlling the external  flow of particulate material recycled to a fluidized bed combustor.  The segmented insert is insulated to protect the horizontal conduit and the individual segments are joined together by a combination of a collar and hinge means.   This method of coupling retains the co-axial  alignment  of  the  individual  segments  for  leak-free operations while also enabling them to move or pivot independent of  each  other  while  still  being  connected  together.   Such independent movement is necessary for stress release purposes during high temperature operation.

Title: Moisture - separator - reheater drain cooler system
Inventor: VISCOVICH PAUL W
IPC: F01D17/24
Filed: 1991-11-06
Abstract: 56,205 ABSTRACT OF THE DISCLOSURE     A steam turbine system has a plurality of moisture-separator-reheaters (MSR) each connected via a respective drain line to a corresponding drain receiver.  Each drain receiver includes a further drain line coupled through a flow control valve to a common line.  The common line empties into a drain cooler connected at the highest pressure end of a series of feedwater reheaters.  The drain cooler dumps through another flow control valve to one of the feedwater heaters.   Each of the drain receivers includes a pressure sensor and liquid level sensor.  A control processor monitors the pressure sensors and selects the drain receiver subjected to the lowest pressure.  The processor then fully opens the valve associated with the selected drain receiver and thereafter regulates the liquid level in the others of the drain receivers by adjustment of their respective flow control valves in response to their respective level sensors.  The liquid level in the selected drain receiver is adjusted to its preselected level by control of the flow control valve connected to the drain cooler.  The pressure in the common drain line is regulated to the pressure at the lowest pressure drain receiver by adjustment of the control valves associated with the other drain receivers.
Patent CA-2058917-A1 (CA)
Title: Captrap
Inventor: GRAHAM ALAN R
IPC: C12H1/02
Filed: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE In the process of making liquid substances sediment may accumulate at the bottom of the containers in which said liquid is retained.  It is known that, by inverting such a container, undissolved particles may then deposit in the form of sediment at the container opening and be drawn out.      In this invention, a closure cap, attachable to and releasable from the neck of a container, comprises an inner wall lying flush with the interior surface of said neck and having for its interior surface  an upwardly tapering cross section extending into the container opening to form at its apex an inlet means.  Said interior surface extends beyond the inlet means with an upwardly expanding cross section to form a conical chute, such that undissolved particles, from liquid retained inside the container to which the closure cap is attached, may flow into the closure cap if the container is inverted.  Once downstream of said inlet means, sediment may be caused to accumulate in a deposit chamber, being the internal volume of the closure cap defined by the interior surface of its walls.  Upon a process in said container being complete and the container uprighted, a freely disposing valve at the inlet means will restrict the passage of sediment collected in the deposit chamber back into the container, thus, confining the sediment inside the closure cap.  The sediment may then be disposed of by removal of the closure cap from the container.

Title: Method and apparatus for structural attachment of polycarbonate plastic sheet to supporting strength members and air cargo container utilizing same
Inventor: LOOKER ROBERT
IPC: B65D88/14
Filed: 1991-05-21
Abstract: In order to be able to utilize polycarbonate sheet material (12) as a structural (i.e. stress-bearing) component in an assembly comprising polycarbonate (12) and metal (10) components, as, for example, in a monocoque air cargo container wherein the polycarbonate sheet material (12) is used as the "skin" of the structure, an attachment assembly is utilized to provide a rigid, stress-bearing joint without inducing crack-inducing high levels of localized stress on the polycarbonate sheet (12). The attachment assembly (14) comprises a significant area of overlap between the polycarbonate (12) and metal (10) components, and an attachment strip (14) which substantially covers the attachment area, Rivets or bolts (16) are inserted through oversized holes in the metal (10), polycarbonate (12), attachment strip assembly (14) and then torqued. The compressive forces exerted thereby create the rigid joint (even in an environment where the joint is subject to 180 °F~ temperature cycling such that the different coefficients for thermal expansion for the polycarbonate vs. the metal become significant) but are spread over a sufficiently large area so as to avoid high, localized stress levels which would induce the polycarbonate to crack.
