Abstract: A combined second relief valve and restricted orifice is located downstream of the relief valve stack on a vent line. The second relief valve opens at a pressure greater than that of the relief stack. When the second relief valve is closed, vapor is vented through the restricted orifice at high velocity, and when the second relief valve is open, the vapor vents from the unrestricted end of the vent line at high volume.

Abstract: Disclosed is a method for killing animal pests infesting a water-bearing product and including placing the product in a chamber having at least some oxygen therewithin and reducing the pressure in the chamber below atmospheric pressure. The improvement comprises the steps of reducing the pressure in the chamber at least to the boiling point of the water in the product so that oxygen in the chamber is displaced by water vapor until the chamber is substantially oxygen depleted. The oxygen depleted condition is maintained for the "time of lethality," i.e. for a time at least equal to the time required for a pest to be killed in an oxygen-depleted environment. Specific aspects of the new method also involve using inert gas and a poison gas fumigant.

Abstract: There is disclosed a self-pressurizing container for liquid helium which comprises an inner and outer vessel with an insulating space between. A heating element is disposed within an insulating barrier tube which extends between the liquid and vapor phases of the helium. The barrier tube insures that the liquid helium is heated and vaporized in the barrier tube without substantially heating the bulk of the liquid helium. The heating element in the preferred embodiment includes a vapor heat exchanger.

Abstract: There is disclosed a syrup delivery system for carbonated beverages which provides delivery of beverage syrup from a syrup container to a beverage mixer. The syrup delivery system comprises a source of pressurized gas, conveniently the CO.sub.2 gas source which is also used to carbonate the water used to mix the carbonated beverage, and a syrup container. The syrup container comprises a rigid drum having an opening with a closure and a pressurizing fitting for connection to the source of presurized gas. A collapsible bag for holding the syrup is fitted inside of the rigid drum and is connected by means of a double ended connector through the closure to the beverage mixer. In operation, the CO.sub.2 pressurized gas is introduced into the rigid tank between the inside of the tank and the outside of the collapsible bag thereby forcing the syrup out of the bag and to the beverage mixer at a constant pressure. Because the closure is a standard size to fit existing small and large syrup containers, the syrup deliver system can be retrofitted into existing bulk on-premises syrup containers as well as retrofitted into smaller existing syrup containers. In both cases, the need to clean and sanitize the syrup containers is eliminated.
Abstract translation: 公开了一种用于碳酸饮料的糖浆输送系统，其将饮料糖浆从糖浆容器输送到饮料混合器。 糖浆输送系统包括加压气体源，方便地也用于碳酸化用于混合碳酸饮料的水的CO 2气体源和糖浆容器。 糖浆容器包括具有带有封闭件的开口的刚性鼓和用于连接到预定气体源的加压配件。 用于保持糖浆的可折叠袋装配在刚性滚筒的内部，并且通过双端连接器通过封闭件连接到饮料混合器。 在操作中，将二氧化碳加压气体引入容器的内部和可折叠袋的外部之间的刚性罐中，从而迫使糖浆以恒定的压力从袋中取出并进入饮料混合器。 因为封闭物是适合现有小型和大型糖浆容器的标准尺寸，糖浆输送系统可以被改装到现有的散装内部糖浆容器中，并且被改装成较小的现有糖浆容器。 在这两种情况下，消除了对糖浆容器进行清洁和消毒的需要。

Abstract: A cryogenic liquid storage tank has an automatic pressure relief means which vents vapor while the tank is being filled so that the tank may be completely filled. The pressure relief means includes a float which, when the cryogenic tank is filled, automatically closes the pressure relief means. In an alternative embodiment, the pressure relief means is combined with an eductor attached to the tank's inlet. The eductor entrains and condenses vapor within the tank to minimize the amount of vapor vented by the pressure relief means.

Abstract: An improved cryogenic liquid storage tank features a main tank containing a ullage tank. The top portion of the main tank communicates with the bottom portion of the ullage tank through a pipe segment and an opening in the ullage tank. The pipe segment is dimensioned and positioned so that the main tank fills with incoming cryogenic liquid while the ullage tank remains primarily empty. The restricted flow into the ullage tank causes the flow of cryogen into the main tank to decrease when the main tank is nearly full. This decrease in flow is utilized to terminate the filling of the tank. Removal of product from the main tank decreases the pressure and the liquid level therein so that liquid flows out of the ullage tank and is unable to return.

Abstract: The fueling station consists of a vacuum insulated storage vessel for storing a large quantity of LNG at low pressure. The LNG is delivered to one of two relatively small volume fuel conditioning tanks where the pressure and temperature of the LNG can be raised or lowered as dictated by the needs of the system. The pressure and temperature in the fuel conditioning tanks are raised by delivering high pressure natural gas vapor thereto from a high pressure bank. The temperature and pressure can be lowered by venting natural gas from the fuel conditioning tanks and/or delivering LNG thereto. The fuel conditioning tanks are connectable to a vehicle's fuel tank via a fill line to deliver natural gas and LNG to the vehicle and to vent natural gas from the vehicle to the fueling station.

Abstract: A relief valve is provided in the dip tube line that provides a fixed back pressure of 2-3 psi. When the economizer valve on the economizer circuit opens, the back pressure in the dip tube is the head pressure plus the 2-3 psi created by the relief valve. This pressure creates a path of least resistance through the economizer circuit such that the demand of product will draw gas from the gas head via the economizer line until the pressure falls below the valve set at the regulator. Once the pressure falls below the valve set at the regulator, the regulator closes the economizer circuit and liquid will be drawn through the dip tube. Because the relief valve prevents flow back into the tank, an orifice is provided to allow back flow of the cryogen from the withdrawal line to the tank once delivery of product is stopped.
Abstract translation: 在汲取管线中提供安全阀，其提供2-3psi的固定背压。 当省煤器回路上的节能阀打开时，汲取管的背压是头压力加上由安全阀产生的2-3 psi。 该压力产生通过节能器回路的最小阻力的路径，使得产品的需求将经由节能器管线从气体头部吸入气体，直到压力降到调节器下方的阀门的下方。 一旦压力降到调节器下设置的阀门下方，调节器关闭节能器回路，液体将通过汲取管进入。 因为安全阀防止流回到罐中，所以提供孔口，以便一旦产品停止运送就可以将冷冻剂从抽出管路回流到罐中。
