Title: Critical power enhancement system for a pressurized fuel channel type nuclear reactor using chf enhancement appendages
Inventor: SOLLYCHIN RAYMAN
IPC: G21C3/06
Filed: 1995-03-01
Abstract: A critical power enhancement system is pro-vided for a pressurized fuel channel type nuclear reactor comprising a plurality of fuel bundles (20) contained in a fuel channel and containing a plural-ity of fuel elements (22) horizontally oriented within the fuel channel.  The system comprises at least one appendage (30) strategically located on each of cer-tain fuel elements along its length and projecting outwardly from the surface of the fuel element.  The appendages (30) generate turbulence in the coolant flowing at locations along the length of the fuel bun-dle, where the critical heat flux is most likely to oc-cur. The presence of the appendages suppress the occurrence of the critical heat flux in the fuel bundle thereby increasing the safety limit on the maximum power that can be produced by the reactor.

IPC: C07F15/02
Filed: 1994-05-20
Abstract: Polyamino disuccinic acids are effective chelants for use in gas conditioning (preferably involving the poly-amino disuccinic acid in the form of a metal, preferably an iron complex). The copper chelates are also useful in electroless copper plating. In electroless deposition, the invention includes a method of electroless deposition of copper upon a non-metallic surface receptive to the deposited copper including a step of contacting the non-metallic surface with an aqueous solution comprising a soluble copper salt and a polyamino disuccinic acid and plating baths appropriate for such use. Another aspect of the invention includes a method for removing iron oxide deposits from a surface including a step of contacting the deposits with a solution comprising an ammoniated polyamino disuccinic acid. Yet another aspect of the invention involves gas conditioning including a process of removing H2S from a fluid comprising contacting said fluid with an aqueous solution at a pH suitable for removing H2S wherein said solution contains at least one higher valence polyvalent metal chelate of a polyamino disuccinic acid and a process of removing NOx from a fluid comprising contacting the fluid with an aqueous solution of at least one lower valence state polyvalent metal chelate of a polyamino disuccinic acid.

Title: Double-c clip
Inventor: VENETTACCI ALDO
IPC: F16B7/04
Filed: 1996-07-11
Abstract: It is the object of this invention to facilitate the attachment of two cylindrical bars that are to be joined perpendicularly to each other. The present invention allows fastening of bars without the use of any tools. Different from other attachments which make use of nuts and bolts, the present invention includes a simple attachment which snaps into place in order to secure two bars together at any location along the length of any of the two bars. Unlike nuts and bolts which project from the bars, the Double-C clip has no protrusion thus eliminating any snagging. It is also the object of this invention to allow the disassembly of perpendicular bars with the least amount of time and effort possible. The present invention provides a device that is small, lightweight, easy to manufacture and simple to use. It is designed with the minimum amount of material which allows simple manufacturing and effortless assembly. The present invention can be used for, but not limited to, any shelters constructed with the use of bars such garage tents, awnings, canopies sunshades, etc. The user is not limited by the size of the bars that need to be attached, since the present invention can be made in different sizes.

IPC: B65H1/30
Filed: 1996-03-13
Abstract: A partition feeder (10) has a multi-rack assembly for holding more than one reserve stack of partitions (14). The partition feeder (10 has a main stack of partitions which is forced against a set of tabs (18) and which has its partitions (14) removed by a selecting apparatus (32). When the main stack has been reduced down past a certain amount, one of the reserve stacks is automatically moved into alignment with the main stack and the partitions (14) in the reserve stack are added to the main stack. The partition feeder (10) has guide rails that are received in notched sides of the partitions, thereby suspending the partitions (14) on the guide rails (12). An inner frame (166) upon which the guide rails (12) are mounted, is adjustably mounted to a middle frame (164) to thereby permit the adjustment of the distance between the guide rails (12). The partition feeder can therefore be easily adjusted for partitions of different sizes.

IPC: B27G13/04
Filed: 1995-08-01
Abstract: An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring (2), cutting knives (10), holding locations (8) mounted on the disc or ring (2) to receive the cutting knives (10), clamping members (35) to engage and hold the cutting knives in position and fasteners (36) to mount the clamping members to the holding locations. The improvement comprises providing a surface (30, 40) having an undulating profile to engage against the cutting knives (10). The undulating surface can be formed on the clamping member (35), at the holding location (8) or at both locations. The surface is shaped to deform to engage the cutting knives (10) with a uniform clamping load upon securing of the fasteners (36) to a pre-selected torque. The foregoing arrangement requires fewer fasteners (36) while still maintaining an adequate clamping force on the cutting knives (10). This makes parts less expensive and reduces the time to change the knives (10) as there are fewer parts to loosen and tighten.

Title: Flooring system for farrowing pen
Inventor: CHURCH KENNETH S
IPC: A01K1/015
Filed: 1997-02-11
Abstract: Flooring for a farrowing crate particularly for pigs is formed of beams and support flanges which are manufactured of glass fiber reinforced resin so as to be electrically insulting. The beams span a pit for receiving manure. On top of the supporting structure is provided a flooring formed of a plurality of rectangular panels or tiles arranged side to side and edge to edge to form an array of the panels. An area under the sow is defined of pressure molded aluminum panels and an area fully surrounding an island of aluminum panels is defined by panels of injection molded plastics which are again relatively non-conductive. The steel structure of the farrowing crate is bolted to the plastics panels at positions forwardly and rearwardly of the island of aluminum panels. Thus the aluminum panels are electrically insulated from any electrically conductive element within the farrowing crate to prevent galvanic corrosion of the aluminum panels.
