  • Patent number: 7147206
    Abstract: A quick connect coupling includes male and female elements of which one includes a closure valve that is spaced inwardly from an open end of the one element and that is opened by engagement of the other element after a portion of the other element passes through an annular opening in the one element. To prevent accidental opening of the valve, a ratio of a radial width of the annular opening and a depth of the annular opening between the valve and an entrance into the annular opening is less that 1.

  • Patent number: 6822104
    Abstract: Methods for sequential saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in a polyether alcohol solvent to yield soaps with conjugated double bond systems are disclosed. The novel properties of the polyether alcohols allow the removal of water added with the alkali by boiling. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps. The reaction forms equal quantities of 9Z,11E-octadecadienoic acid and 10E,12Z-octadecadienoic acids.

  • Patent number: 5762386
    Abstract: A tamper resistant seal and a method of sealing an object using the tamper resistant seal are disclosed. The seal includes a receptacle and an insert adapted to be received in the receptacle. A tamper indicating wire is partially embedded in the insert and protrudes from an end of the insert. When the seal is assembled the insert is received in the receptacle and the wire extends along channels formed in opposite faces of the insert. If the wire is severed or removed from the channels by a tamperer attempting to break the seal, the structure of the channels prevents the wire from being repositioned therein to give a false indication of non-tampering. In addition, the receptacle is transparent to enable the wire to be visually examined to determine whether tampering has occurred.

  • Patent number: 5755181
    Abstract: An electro-mechanical animal waste container for deodorizing fumes from animal waste is disclosed. The container includes an open frame, a tray, a fume hood and a sensor. The frame has a base and the tray is positioned therein. The tray is for receiving animal waste. The fume hood is attached to the frame and is spaced above the tray. The fume hood has an outlet port formed therein. A fan is positioned in the fume hood such that the fan draws the fumes from the tray into the fume hood and toward the outlet port. The sensor determines when there is an animal in the tray. A control circuit is operably connected to the sensor and the fan wherein when the sensor detects an animal in the tray the fan is switched on after a preselected amount of time and then after a second preselected amount of time the fan is switched off. Preferably a filter is positioned over the outlet port and is for deodorizing air that passes therethrough. Preferably a second filter is positioned at the bottom of fume hood.

  • Patent number: 5743308
    Abstract: A double-lift weave system comprising a plurality of hooks, each of which is provided with two arms mounted on a base and each of which includes a lift lip adapted to cooperate with one of the knives of two griffe frames moving in phase opposition in a reciprocating movement. The position of each lip is controlled in order to be selectively moveable with respect to a knife by an actuator disposed between the two arms. Each hook further includes two open shed heels which are controlled by the actuator and adapted to cooperate with open shed bars so as to be moveable with respect to the bars. The system is particularly applicable to weaving looms.
