Abstract: Novel manifolds and methods of flow through manifolds are described. Apparatus and techniques are described in which flow from a relatively large volume header is equally distributed to process channels. Methods of making laminated, microchannel devices are also described.

Abstract: Hydraulic valve actuation systems and methods to provide variable lift for one or more engine air valves by way of a variable position hard stop. Various embodiments are disclosed, including embodiments controlling lift by providing a choice of two different fixed stops, three different fixed stops, stops continuously variable throughout a range of lifts, and a fixed stop and stops continuously variable throughout a range of lifts. The valves controlled by a variable position hard stop may be a single engine intake or exhaust valve, or multiple valves of any number, and of either intake or exhaust valves or both, or of one intake or one exhaust valve for one or more cylinders in engines having more than one intake or exhaust valve per cylinder. Dashpot deceleration of engine valve velocity on opening to the hard stop and on engine valve closure is disclosed, as are other aspects and embodiments of the invention.

Abstract: Integrated Combustion Reactors (ICRS) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

Abstract: A system and method of controlling distribution of electronic information to a device through a non-bidirectional protocol is disclosed. At a user device, a segment of encrypted electronic information is retrieved. Identification data is sent from the user device using the non-bidirectional communications protocol, where the identification information includes at least one of information associated with a user, information associated with the user device, or information associated with the segment of encrypted electronic information. A copy of an encryption key for the segment is retrieved. A voucher is forwarded to the user device using the non-bidirectional communications protocol, the voucher including at least the encryption key associated with the segment. At the user device, the segment is decrypted using the encryption key for the segment.

Abstract: A unitary one-piece mounting bracket for mounting a meter transponder at the top of a rod or tube in connection with utility meters that are located in subsurface pit enclosures. The mounting bracket includes multiple blind receptacles to receive the rod or tube and supports the transponder without the need for removable fasteners.

Abstract: A die assembly for machines used to bend lengths of pipe for pipeline applications. The die assembly includes three major components, an exterior housing, a flexible die, and an eggcrate assembly. The exterior housing encompasses the flexible die and eggcrate assembly and pins into conventional bending machines. The flexible die includes a plurality of narrow plate segments positioned along a pair of tie rods. The plate segments are free floating and spaced so as to converge or diverge with respect to the direction of flex of the tie rods. The eggcrate assembly provides support for a plurality of spring plates. Each spring plate has a radius of curvature consistent with the amount of desired bend in the length of pipe.

Abstract: A method of limiting core deflection in the manufacture of relatively long sections of progressing cavity pump production tubing wherein a core is held within the bore of a length of tubular casing to provide a form for the molding of a stator element. The core is centered and stabilized within the tubular casing at selected intervals prior to the injection of elastomeric material by one or more core centering bearings. The bearings are effective to prevent core deflection during manufacture and, rather than being removed after curing of the stator, are left in the casing to function as rotor bearings for the progressing cavity pump. The bearings, themselves encapsulated by elastomeric material during the manufacturing process, help maintain the rotor in optimal alignment within the production tubing thereby benefitting pump performance and longevity.
