A method of manufacturing opening tabs for containers comprises providing sheet material, from which tabs are to be formed, with locating apertures. The sheet material is located within a printing machine and printed information is applied to the sheet material at predetermined locations. The pre-printed sheet material is then located on a forming machine and opening tabs are formed in the location of the pre-printed information and applied to can opening ends.

A highly efficient circulator system is provided, useful for hydronic systems, including both heating and cooling systems. The stand-alone circulator motor is controllable by input from certain sensors, preferably thermal sensors, which provide data enabling the controller of the brushless pump motor to vary its flow output to meet changes in systems loads. The circulator has a ceramic permanent magnet rotor, such as a ferrite, with an electronically, preferably sinusoidally, commutated, electro-magnetic stator controlling the input of electrical power.

A container holder is disclosed which includes a base member and plural foam members. The base member has a central hub portion from which a plurality of spaced apart leg portions extend generally outwardly each in a different directions. A plurality of upright portions also extend from the hub but in a generally upwardly direction from locations between adjacent leg portions. A foam member is attached to an inward face of each of the upright poritons in a manner such that outer ends of said leg portions are positioned to rest aganist a generally flat surface, such as the floor of a van or truck, to provide a stable support and the foam members are positioned and spaced to receive and support a wide range of container sizes and shapes.
摘要:
A method of making a bipolar transistor in an LSI or VLSI process which includes forming a buried DUF collector of a first conductivity type, growing an epitaxial layer of a first conductivity type over said DUF collector and forming isolation means around a transistor region. The transistor region includes a trench which at least partially encloses the transistor region and extends through the DUF collector. Emitter and base regions of the first and second conductivity types, respectively, are formed in the epitaxial layer. A collector contact region of the first conductivity is formed in the epitaxial layer and extends down to the buried DUF collector.
摘要:
A method of determining the real time bubble point pressure of a fluid originating from a subsurface earth formation using an adjustable choke positioned downhole adjacent to the formation. The adjustable choke is placed into communication with the wellbore fluid flowing from the formation to the surface. The adjustable choke has a remotely adjustable choke opening for selectively restricting the flowrate of the fluid flowing through the choke. The adjustable choke has a pressure sensor for measuring the fluid pressure downstream of the choke opening. The method includes obtaining downstream fluid pressure data as a function of choke size for generating a plot of downstream pressure versus choke size data which exhibits substantially linear behavior having two different slopes. Extrapolating a best-fit line through the set of data having a first slope so as to intersect an extrapolation of a best-fit line through the set of data having a second slope thereby provides the bubble point pressure of the fluid as the pressure corresponding to the intersection of the two lines.

A portable vibration monitoring probe is provided which comprises a housing, a probe and a transducer is provided. An analog to digital converter is coupled to the transducer output. The vibration monitor comprises an interface configured to transmit digital data comprising vibration parameters derived from the digitized analog signal to processing circuitry external to the housing. In some embodiments of the present invention, vibration monitors may be configured to store information in a memory located near the measuring point.

The present invention relates to an apparatus for preventing scaling and/or removing scale in a housing defining a hydraulic environment. The apparatus includes a non-metallic element, at least two coils wound around the element, and a control means. The non-metallic element is retrofittable or incorporable into the housing. The control means is operably coupled to the coils for provision of a magnetic field. The control means includes a microcontroller adapted to cooperate with a switching amplifier to form a closed loop for generation of the magnetic field of a predetermined strength.
