Title: Toilet bowl discharge valve assembly comprising a pivotable gate valve to control flow from outlet to trap
Inventor: JORSCH THOMAS C
IPC: E03D11/10
Filed: 2007-09-13
Abstract: Disclosed is a toilet (10) comprising a bowl (12), a trap (16) and a trap valve (18). The bowl (12) has a lower discharge outlet (14). The trap (16) is in fluid communication with the discharge outlet (14). The trap valve (18) is positioned to control outflow from the discharge outlet (14) through the trap valve (18). The trap valve (18) comprises a valve housing (28, 30), a gate valve (32) and a sealing gasket (36). The valve housing (28, 30) has an entry (34), an exit and a cavity connecting the entry (34) and exit. The gate valve (32) is positioned in the cavity and is pivotable using linkage (52) that extends from outside the valve housing (28, 30) to the gate valve (32). The gate valve (32) is in a form of spherical segment having a radius of curvature extending from a centre of curvature. The gate valve (32) is positioned relative to the sealing gasket (36) so as to begin closing off the entry (34) when a lead edge of the gate valve (32) is within 40 degrees of vertical. The gate valve (32) is mounted to the valve housing (28, 30) so that it is linked to the valve housing (28, 30) so as to pivot relative thereto about a center of rotation offset from the center of curvature. This creates an eccentric closure of the gate valve (32) against the sealing gasket (36). The trap (16) has a normal trap water level (24) to restrict back flow of sewer gases to the bowl (12). The gate valve (32) is positioned so as to be entirely above that water level (24) in both the first position and a fully open position.

Title: Enzymatic process for reducing the fluoride content of proteinaceous concentrates ferived from crustaceans
Inventor: JANSSON KRAGH STIG TORE
IPC: A23L5/20
Filed: 2009-09-14
Abstract: Fluorine being present in the exoskeleton of crustaceans, and especially krill represents a problem for using krill as a source for food, feed, food additives and/or feed additives. There has been developed a process for removing such fluorine from krill material by subjecting the krill to disintegration and to an enzymatic hydrolysis process prior to or simultaneously with a removal of the exoskeleton particles producing a fluorine-reduced product. Inherent in the disclosed process is the ability to process krill material with a high polar lipid content for producing superior quality, low fluorine, products suitable for the food and feed as well as the pharmaceutical, neutraceutical and cosmetic industry. The disclosure particularly relates to a process for for removing fluorine from a catch of crustaceans, wherein the crustaceans, immediately after having been landed and at a temperature of around ambient temperature of the water, are disintegrated into smaller particles, and to the disintegrated material there is added fresh water and a proteolytic enzyme or proteolytic enzyme composition, said mixture being heated to a temperature optimal for the activity of said proteolytic enzyme or proteolytic enzyme composition, and at which temperature the added enzyme(s) is/are allowed to work for no longer than 100 minutes, the hydrolysed material being fed to a separating device for separating solids from the processed material, and through this removal of the solids fraction 10 thereby reducing the fluorine content of the remaining proteinaceous material by at least 85%, the added (exogenous) and natural (endogenous) enzymes in the hydrolysing disintegrated proteinaceous material being deactivated before, during, or after the removal of the solids fraction from the enzymatically processed material, said deactivation being conducted alternatively by adding inhibitors, by removing co-factors, or by thermal inactivation.

Abstract: 595493 Disclosed is an internal combustion engine to increase the dwell period of the piston at TDC to improve the efficiency and operating characteristics of the engine. The engine comprises a piston configured to move within a piston cylinder throughout a stroke cycle and a rotatable crankshaft comprising a crankshaft cam surface. A connecting rod assembly comprises a piston connecting rod pivotally connected at one end to the piston and a crankshaft timing rod pivotally connected at one end to the piston connecting rod at a conrod joint and at another end to the crankshaft. A rocker arm is configured to contact the profile of the crankshaft cam surface during its rotation cycle at one end and is pivotally connected to the rocker arm connecting rod, which is in turn pivotally connected to the conrod joint. The rocker arm and rocker arm connecting rod are together configured to move the conrod joint as the rocker arm is moved on the crankshaft cam surface to form a working crank angle between the piston connecting rod and the crankshaft timing rod when the piston is at its top dead centre (TDC) position. At its position of maximum displacement within the piston cylinder during a piston stroke cycle, the travel of the piston is slowed through the TDC position and the position of maximum displacement during the piston stroke for a predetermined angle of rotation of the crankshaft.

Patent RO-79759-A (RO)
Inventor: SCHLEIMER FRANCOIS
IPC: C21C5/32
Filed: 1980-04-30
Abstract: A process for refining a metal bath in a converter by oxygen blowing, particularly a molten metal liquid bath containing cold, solid substances, notably of scrap. Oxygen is distributed over the surface of the bath, so that there will be an after-combustion of CO released in the course of decarbonization. The thickness and consistency of a slag layer formed over the bath is actively regulated by injecting a rising inert gas through the bottom of the bath. The flow of rising gas may be regulated depending upon the oxygen content in the fumes of the converter, or upon the intensity of emission through the top of an oxygen blowing lance.
