Patent CA-2212620-A1 (CA)
Inventor: HENWOOD GERARD S
IPC: F16K5/06
Filed: 1996-02-06
Abstract: Straight line flow rotary valves with the valve member flow passage (21) turned away from the pipeline flow axis (22), to dispose the valve internals to an access port (50) located downstream on the same flow axis of the valve member (11). Another embodiment is used in place of pipe elbows where the rotary valve internals are accessed through a port (50) on the same flow axis (22) as the upstream pipe. In both valve body embodiments, the flow is turned again, downstream of the valve member (11), to communicate with the connecting downstream piping which, in the first embodiment is along the same axis as the upstream pipe (22), and in the second embodiment, is on a different axis (39), and, is generally (45 or 90) degrees turned from the upstream pipe. In both embodiments the flow turns in a component (12) installed, through the body access port (50). In all embodiments the turning component also services as the pressure boundary access cover over the body opening (50). In a variety of embodiments the turning component (12) additionally services as the valve seat (13), and as a behind the seat seal (16). Sealing member embodiments include floating and trunnion-mounted ball and partial ball valves, and butterfly valves. The preferred embodiment of butterfly valve has a removable resilient seal material (71) such as PTFE or a graphite-based laminate, retained to the valve disc member (11) to facilitate complete repair of all flow isolation surfaces without having to remove the disc member from the valve through the access port (50). Method for removing and installing valve internals through the access port is disclosed.

Abstract: A method and system for compositing graphical images, wherein an advanced adjustment layer may be applied during a compositing process to a set of image layers 1 ... n, or to any subordinate subset of such image layers. One or more adjustment layers are applied to an intermediate merged image, generated by compositing previous image layers, and the adjusted result is stored as a temporary image.  The temporary image is then in turn composited with the intermediate merged image.  Any remaining image layers are then composited in with the intermediate merged image to generate a final merged image.  The invention allows a user to apply a vast array of effects without requiring significant new knowledge on the part of the user.  For example, if there are "A" adjustments and "T" transfer modes, the present invention allows AxT effects which leverage existing knowledge of the user of only A+T functions.

Title: Dual coil drive with multipurpose housing
Inventor: BUTTON DOUGLAS J
IPC: H04R9/02
Filed: 1995-11-13
Abstract: An improved electromagnetic transducer able to produce more power per mass than a conventional transducer. This increased power per mass is made possible by combining a properly designed housing, a neodymium magnet and a dual coil structure. This design dissipates the heat generated by the transducer, increasing the efficiency and power of the transducer. Also, by dissipating heat more efficiently, the transducer can be made smaller and more powerful than conventional transducers.

Title: Manufacture of xylanase complex using pre-treated thin stillage of rye
Inventor: RINGPFEIL MANFRED
IPC: C12R1/885
Filed: 1998-08-18
Abstract: A process for the manufacture of a xylanase-rich enzyme complex by the cultivation of a xylanase-producing microorganism of the genus Trichoderma in a nutrient medium comprises using in the cultivation a pre-treated thin stillage of rye as the xylanase inductor and simultaneously as the carbon source, with the pre-treatment comprising a removal of the solid constituents of the thin stillage of rye, a concentration of the non- volatile components by evaporation of water and other volatile substances as well as a subsequent autoclaving of the thin stillage of rye concentrate resulting therefrom. In a further aspect of this process in accordance with the invention , de-oiled soya meal or soya meal liquor is used as an additional xylanase inductor and as a nitrogen source; by the addition of the de-oiled soya meal or soya meal liquor to the pre-treated thin stillage of rye a further increase in the xylanase production is achieved. The enzyme complexes manufactured by the process in accordance with the invention can be used immediately in the animal feedstuff industry, especially in poultry nutrition; their use in, for example, rye-, barley- or triticale-containing feedstuffs has a favourable influence on the reduction of the antinutritive action of the non-starch polysaccharides and leads to an improved digestability and absorption of the nutrients in the intestine of the animal.

Title: On/off control device for power source unit
Inventor: MATSUYAMA HIROTSUGU
IPC: H02J7/00
Filed: 1998-10-20
Abstract: A voltage detection circuit 2 detects a voltage of a battery 1 and, when the voltage thus detected is within a tolerable input voltage of a power source unit 5, an on/off signal transmitter circuit 4 allows an on/off signal generator circuit 3 to transmit an on/off signal S2 to the power source unit 5. When the voltage of the battery 1 becomes lower than a lower limit of the tolerable input voltage range of the power source unit 5 due to increase of a power consumption of a load 6 thereof, the on/off signal transmitter circuit 4 transmits an off signal S3 to the power source unit 5 regardless of the on/off signal S2 from the on/off signal generator circuit 3 . Thus, it is possible to prevent an erroneous operation of the load due to abnormal operation of the power source unit.
