Abstract: Devices, guards and shields and methods for both protecting sprinkler heads and preventing unwanted vegetation from growing adjacent to the sprinkler heads, which can be applied to most if not all sprinklers on the market. The novel devices, guards and shields can be formed from a two part (upper and bottom part sections) forming a housing with ring shape housing dry and/or liquid herbicides. The ring shape can have a large center hole for allowing the ring shape to be positioned over and about the sprinkler head. The ring shaped housing includes drainage openings through the top and bottom half sections for allowing water from the sprinkler or rain water to pass therethrough and onto a replaceable herbicide which can kill unwanted vegetation such as grass, weeds, roots, trees, from growing adjacent to the sprinkler head.

Abstract: A pressure relief system and a non-intrusive, low chatter pressure relief valve for use with such as system are disclosed. The pressure relief valve allows excess pressure in a pressurized fluid line to flow through a flow return line to a fluid reservoir when the fluid pressure exceeds the valve's pressure limit setting. The establishment of a uniform channel between the valve stem and the inner surface of a housing in which the valve stem is slidably located, as well as the use of a vent and sight tube to remove air from the top portion of the housing upon a spring being compressed during the opening of the valve, reduces the occurrence of pulsation and vibration when the valve is cycled between its open and closed positions. When the valve is in its closed position, the bottom end of the valve stem is in close proximity to the inner surface of the main fluid passageway in the pressurized fluid line, but does not intrusively interfere with the flow of fluid through the main fluid passageway.

Abstract: In a fuel injection device, a pressing surface of a pressing member presses an opening wall surface to interrupt communication between an inflow port and a pressure control chamber when communication between an outflow port and a return channel is made by a pressure control valve, and the pressing surface of the pressing member is displaced and separated from the opening wall surface to open the inflow port of the opening wall surface to the pressure control chamber when the communication between the outflow port and the return channel is interrupted by the pressure control valve. One of the pressing surface of the pressing member and the opening wall surface of the control body is provided with an inflow depressed portion and an outflow depressed portion partitioned from each other, and a depressed dimension of the inflow depressed portion is larger than a depressed dimension of the outflow depressed portion.

Abstract: A brace for a wall-mounted toilet, particularly useful for wall-mounted porcelain toilets in hospitals and other health care facilities. The brace a weight receiving structure supported by cantilevered struts that attach the brace to the wall, preferably using the same bolts that attach the toilet to the wall. The weight receiving structure may be seat portion that overlies the rim of the toilet bowl, so that the weight of the user is transmitted from the toilet seat to the seat structure and then to the walls through the struts. Alternately, the weight receiving structure may include an under-bowl support that extends underneath the toilet bowl so that the user's weight is transmitted from the bowl to the wall through the struts. Thus, the cantilevered brace increases the weight-bearing capacity of the wall-mounted toilet. A plastic shroud may be included for enclosing the brace and toilet bowl.

Abstract: A fuel injection valve co-injects a liquid and a gaseous fuel into the combustion chamber of an internal combustion engine. A solid needle regulates the injection of liquid and gaseous fuels from a cavity in the fuel injection valve into the combustion chamber when the needle is lifted to its open position. In preferred embodiments, liquid fuel is metered and pressurized in an intensifier's cylinder provided within the valve body and the liquid fuel is delivered through a restricted flow passage into the cavity where it mixes with the gaseous fuel. The restricted flow passage can be formed by a small passage formed in the valve body or an annular passage between the needle and the valve body.

Abstract: An apparatus for preventing backflow and contamination, and detecting by-pass leaks in a flow control arrangement is disclosed. The apparatus includes a vent line connecting a sweep gas source and a vent. Constant process-inert gas flows from the source through the vent line into the vent. The vent line is connected with the flow control arrangement. Any leakage in the flow control arrangement is channeled to the vent line and swept into the vent along with the sweep gas. As a result, pressure in the flow control arrangement cannot build up and leakage backflow is prevented. A flow switch may be disposed on the vent line for detecting leakage. The sweep gas flow rate is controlled at a constant level that is inadequate to actuate the flow switch and keeps the flow switch ready to actuate by any superimposed leakage. The flow switch detects a leakage when it actuates.

Abstract: Disclosed is a method and device to control a spray pattern produced from a spraying device consisting of a plurality of individual jets that form the resulting spray pattern. The trajectory of each individual jet is controlled by orienting the nozzle-like feature that produces each individual jet, thereby producing a variety of spray patterns. This is accomplished utilizing the flexible properties of elastomeric or rubber-like materials. In addition to allowing for deformation or movement to remove possible obstructions to the fluid flow, this flexibility property also permits for specific, controlled movements, whereby it is possible to control the trajectory of the fluid issuing from the device. These rubber-like materials can include specific features that allow the material to be deformed in a controlled fashion so as to predictably control the trajectory of the streams issuing from the individual nozzles.

Abstract: In the ultrasonic atomization method, a liquid is ultrasonically oscillated in an atomization chamber 4 and a liquid column P is projected in carrier gas to thus atomize the liquid into mists, the carrier gas carrying the atomized mists outwardly of the atomization chamber 4; the carrier gas is forcibly sucked from a lateral point being away at a distance (d1) of 5 cm or less from a center axis m of the liquid column P and thereby a gas flow is blown across the liquid column P; the mists are separated away from the liquid column P by means of the blown gas flow; and such separated mists are transferred outwardly of the atomization chamber 4 by means of the carrier gas.
