Patent CA-2229659-A1 (CA)
Inventor: PEREZ CORBALAN SERGIO
IPC: F16K31/126
Filed: 1997-11-20
Abstract: A flow valve  operated  by flow transfer  means  which regulate a small control flow in order to produce a pressure differential between the sides of the sealing wall of a piston able to axially move between an opened position far from the valve seat, and a closed position in contact with the valve seat.   The valve of the invention basically consists in a rigid valve body with a flow inlet opening and one flow outlet, which are oriented in a substantially cross way to said inlet opening. The body of the valve has a main cavity between the flow inlet and outlet with a valve seat in the limit of the main cavity and the flow inlet. In addition, the body of the valve has one or more ducts for the control flow inlet, and one  or  more  ducts  for  the  outlet  of  the  same  which  are associated with the control flow transfer means of the valve. These inlet ducts of  control  flow may be  supplied  from a network which is independent from the main flow and flows of a nature different  from that of the main flow can be used. Similarly, the outlet ducts of the control flow can discharge it in a network which is independent from the main one.     The valve has an elastomeric body in charge of regulating the  flow  by  its  opening  or  closing,  depending  on  the difference of pressures produced between its walls, which are modified by the flow transfer means which control the flow. The elastomeric body is located inside the main cavity of the valve, said elastomeric body being hollow and opened in one of its axial ends. This elastomeric body is made up of at least two coaxial zones:  one sealing zone and one second zone of radial sealing.  These zones of the elastomeric body perform specific functions during the operation of  the valve,  thus avoiding the participation of separate components,  which is translated  into  a  complex  design  of  the  valve  and  in  an increase of the manufacture costs.

Abstract: The corner mounting machine is equipped with at least one head (14) which has a punching/stamping device for a corner of a frame made of mitered hollow sections (2). Corner connectors are provided in the frame corner within the hollow sections (2), said corner connectors being fixed in position by punchings in the walls of the hollow sections (2). The punchings are carried out with punches (5) which are operated via drive units (23). The corner mounting machine is designed in such a way that one punch design (5) is sufficient to do all punchings in a frame. The punches (5) are arranged with the drive units on a guide block (24) which is symmetrical to a median line (8a) which lies in the miter plane (8) of the frame corner. The guide block (24) is moved along the median line, so that the punch (5) with its drive units travels parallel to the mitering plane. The frame corner rests on a bearing (10) which is provided with calipers (15) and can be adjusted vertically to the frame plane independent of the punches (5). Punchings can be made in various vertical positions of the height of the sections (2). The corner mounting machine may be used for the manufacture of window frames, door frames or frames for façades.

Title: Light reflectant surface for luminaires
Inventor: MINOR RAYMOND B
IPC: F21V7/22
Filed: 1997-04-08
Abstract: The present invention relates to surfaces used to reflect light, and particularly to highly light reflectant surfaces that provide even diffusion of light for the purpose of maximizing light efficiency and/or uniformity in a luminaire. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross sections.
Patent CA-2234790-A1 (CA)
Title: Transparent multiplexer/demultiplexer
Inventor: MARTIN DAVID WRIGHT
IPC: H04Q11/04
Filed: 1998-04-15
Abstract: A configuration for a SONET transport node comprises a pair of transparent mux/demuxs provided at two sites and connected over a high rate span. The T-Muxsprovide continuity of all tribs and maintain a lower bit rate linear or ring system through the higher bit rate span. The lower bit rate linear or ring system operates as if it were directly connected without the higher bit rate midsection. For the forward direction of the traffic, the T-Mux comprises a multi-channel receiver for receiving the trib signals and providing for each trib signal a trib SPE and a trib OH. The trib SPEs are multiplexed into a supercarrier SPE and the trib OHs signals are processed to generate a supercarrier OH. A supercarrier transmitter maps the supercarrier SPE and the supercarrier OH into a supercarrier signal andtransmits same over the high rate span. Reverse operations are effected for the reverse direction of traffic. With this invention, an entire ring system does not have to be upgraded to a higher line rate due to fiber exhaust on a single span. The invention is particularly applicable to OC-48/OC-12/OC-3 linear and ring networks and the high rate span could be an OC-192 line.

Title: Method of suspending an esp within a wellbore
Inventor: BRUEWER TIMOTHY B
IPC: E21B23/00
Filed: 1998-06-03
Abstract: A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. One end of the conduit is sealed with one end of the electric cable extending out therefrom. The conduit is filled with a fluid of sufficient volume and sufficient density to float the electric cable within the conduit when the conduit is disposed within a wellbore. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. Thereafter, the electric submergible pumping system and the conduit are inserted into the wellbore. Since the cable is floating, i.e., self supporting, within the conduit there is no need for cable anchors or other devices to transfer the weight of the cable to the conduit.

Title: Rubber dam and method of application thereof
Inventor: MURAMATSU TATEO
IPC: E02B7/00
Filed: 1999-01-12
Abstract: A rubber sheet is formed in a bag shape, and a seam portion of the bag-shaped rubber sheet is fixed to a summit portion of an overflow dam. When the bag-shaped rubber sheet is expanded, a rubber dam is raised, thereby damming up water and adjusting the amount of running water. Next, when the bag-shaped rubber sheet which has been expanded is contracted and collapsed, the rubber sheet is supported by pipes, which extend substantially horizontally from the summit portion of the overflow dam toward the downstream side at a predetermined distance from each other.      For this reason, the rubber sheet hangs down with its own weight and with the weight of water running downstream so as to droop down between the pipes. As a result, a rubber dam that does not bulge at the downstream side is obtained.
