Abstract: A field configurable contactor is disclosed. The contactor preferably includes a plurality of spaces adapted to receive any number, up to its limit, of contact modules. Each contact module preferably includes a pair of contacts and a spring biased cam follower which opens and closes the contact pair when a cam profile of the contactor moves according to energization or de-energization of the contactor. The contact module can be either “normally open” or “normally closed” depending on its initial placement onto the contactor relative to the cam profile. A latch assembly in the contactor may hold the contactor mechanically during de-energization.

Abstract: An extruded magnetic structure includes a first layer of low alloy steel compressed powder and a second layer of rare earth metal compressed powder circumferentially disposed around the first layer. A third layer of compressed powder may be circumferentially disposed around the second layer.

Abstract: The present invention relates to the development of a positive selection vector based on insertional reconstruction of a reporter gene or of a regulatory gene controlling the expression of a reporter gene. The cloning vector carries a reporter gene or a regulatory gene with a mutation rendering the reporter or the regulatory gene protein functionally inactive. A primer carrying a nucleic acid sequence that corrects the mutation is used during PCR amplification of a targeted nucleic acid sequence, and the amplified DNA fragment is then ligated to the said vector thus reconstructing the wild-type reporter or regulatory gene.

Abstract: The present invention describes a methodology for generating high fidelity PCR products, and also cloning of such high fidelity PCR products in a suitable vector. Generation of polymerase-induced mutant fraction of target sequences during PCR amplification is linearly proportional to the number of doublings of the target sequences. Thus the high fidelity PCR products are generated by minimizing the number of doublings of the target nucleic acid sequences during PCR amplification. Minimization of number of doublings of the target sequences is achieved by reducing the number of cycles of PCR amplification of the target sequences. The high fidelity PCR products thus obtained are then cloned into a suitable vector. As an example, a 960 bp target sequence from E. coli DNA was PCR-amplified only for 3 cycles, and it was then directly cloned into a positive selection cloning vector pRGR2Ap.

Abstract: The present invention describes the development of a positive selection vector based on regulatory element modulation, wherein such modulation is achieved via insertional reconstruction or destruction of a regulatory element controlling transcription, translation, DNA replication and termination. A positive selection cloning vector pREM5Tc has been developed based on insertional reconstruction of a regulatory element of a reporter gene. The vector pREM5Tc carries the tetracycline resistance reporter gene with no functional −35 region of its promoter, a regulatory element, thus resulting in no expression of the tetracycline resistance gene. Hence a host cell carrying the vector pREM5Tc is unable to produce the tetracycline resistance gene protein resulting in inhibition of its growth in presence of tetracycline. An E.

Abstract: A method is provided for manufacturing a multi-layered magnetic rod in which a steel powder is reduced and extruded through a die. To improve the magnetic properties, a layer of rare earth magnetic power formed around the low alloy steel in the extruder chamber. A second layer of coating formed around the rare earth powder and the three layers are co-extruded through the die to produce a layered rod having improved magnetic properties. The resulting magnetic rod may be machined using conventional machining methods.

Abstract: A system provides an order-invariant fuzzy commitment scheme. In an exemplary embodiment, the scheme includes receiving a first set of elements and selecting a polynomial for encoding an item under the first set of elements to generate an order-invariant fuzzy commitment of the item. The system utilizes an error-correcting code for decommiting the item if a second set of elements has a specified level of overlap with the first set of elements.

Abstract: An electromagnetic contactor that provides accurate contactor status indication regardless of the contact position. The primary contacts are secured within reversible contact modules. A contact carrier first end provides accurate local contact position indication. Auxiliary contacts toggled by the operator provide accurate control system status indication. The operator includes a stem with two sets of abutments that cooperatively engage the contact carrier. A catch located at the contact carrier second end and an abutment lip attach if the moveable contacts are welded shut. The operator status is prevented from changing thus insuring the accuracy of the contact position feedback. The contact modules can be installed in the electromagnetic contactor without the use of tools.

Abstract: A ring assembly manufacturing apparatus (30) and method provides heat to a ring (216) such as a polymeric ring from an infrared source (48). A ring assembly (214) includes a ring (216) and a hub (218) within the ring. The ring (216) is traversed into a chamber (46) such that the ring (216) is exposed to infrared energy from the infrared source (48). The infrared energy causes the ring (216) to expand thereby facilitating assembly with the hub (218).
