Abstract:
A weapons system is disclosed that provides hot-start navigational information to the Global-Positioning-System receivers on missiles prior to flight. The system comprises a Global-Positioning-System receiver that uses a classified red cryptographic key to decode the P(Y) signal from one or more of the Global-Positioning-System constellation of satellites. Once the P(Y) signal is decoded, one or more characteristics (e.g., the PRN code synchronization, the Doppler shift, the modulation bit sequence, etc.) of the signal is derived. These characteristics of the signal—and some other information including a black cryptographic key that comprises the red cryptographic key—are then provided to the Global-Positioning-System receivers on missiles prior to flight. By giving the missiles this information, the missiles are able to acquire the P(Y) signals themselves more quickly than they otherwise could, which enables them to determine their position more quickly than they otherwise could.

Abstract:
The apparatus is used for closing and securing a door in its frame. A movable wedge is supported in a slot in the frame. A closing mechanism is employed for closing the door and a second mechanism is employed for moving the wedge into a slot formed in the edge of the door when the door is closed. A shape memory wire is used in conjunction with the closing mechanism for allowing the closing mechanism to close the door. A second shape memory wire is used in conjunction with the second mechanism for allowing the second mechanism to move the wedge from the frame slot into the door slot when the door is closed for securing the door to the frame.
Abstract:
A dividing conveyor system is disclosed for directing articles such as milk bottles traveling along a stem conveyor to either a first or second branch conveyor. The divider conveyor system includes a diverter assembly disposed over the intersection point of the stem, first and second branch conveyors, and a diverter positioner for locating the diverter in an appropriate position to divert articles from the stem conveyor to either of the branch conveyors. A first branch sensor is located near the first branch conveyor and downstream of the conveyor intersection point, and a second sensor is correspondingly located near the second conveyor and downstream of the conveyor intersection point. Appropriate switching circuitry includes logic elements to divert articles from the stem conveyor to a branch conveyor at which the associated branch sensor has sensed the absence of articles on that branch conveyor. If both branch conveyors have been filled with articles, additional articles coming in along the stem conveyor are directed into a storing array against a bumper stop.
Abstract:
The present invention relates to a specific method accomplishing fast and specific identification of contaminating micro-organisms in large amounts of food stuffs. A method has been developed based on random genome fragments or Zipcode oligonucleotides and DNA microarray technology that overcomes the disadvantages of whole-genome DNA-DNA hybridisation. In particular, the present invention provides a method for characterising micro-organisms possibly present in a sample, comprising the steps of collecting said micro-organisms if present, extracting nucleic acids from said micro-organisms, specifically amplifying said nucleic acids, thereby providing an amplified nucleic acid mixture comprising the target nucleic acid in amplified form, and analysing the amplified nucleic acid mixture, whereby the said micro-organisms if present are characterised. The present invention further relates to the use of filters, microarrays and amplification steps in said method as well as a kit comprising the same.
