An improved process for the purification of raw cotton linters includes the cutting of a first, second, third or mill run cut raw cotton linters to a particle size that passes through a 2,500 micrometer screen and then mechanically separating the linters into clean and unclean fractions. The clean fraction contains purified cut raw cotton linters and the unclean fraction contains the impurities.

An electronic security system includes an electronic lock mechanism and an electronic key, each of which is provided with a microprocessor controller and a memory storing data including an ID code and encryption key codes. The lock microprocessor may either change ID codes stored in its memory or encrypt a seed number to be used for determining access to the lock. The key can only be used to access the lock either once or for a limited number of successive times, and must thereafter be reprogrammed by a host computer to be loaded with either the proper ID code or the appropriate encryption key code for that lock. The electronic lock operates a solenoid which retracts a bolt-blocking mechanism that prevents the unlocking of the bolt even when a key having the correct mechanical key cuts is inserted into the lock. Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key. In a preferred embodiment the key unit is composed of a handheld computer and key module interface.

An Archive Interface Manager (AIM) can provide a common interface between the image delivery channels and image archives. AIM handles requests and fulfillment of queries and images between the image delivery channels and the image archive/s. AIM processes requests for documents to the appropriate document archive/s and fulfills and returns a list of items that matches the request and subsequently, the requested item to the requestor. AIM processes the request, searching multiple archives, going to the appropriate place of record, combining the hit list with all the items and returning a single hit list with the matched request. AIM also allows the requestor to query and retrieve items without seeing a hit list such as in a request for a single item.

An imaging apparatus 6 has means for illuminating a selected surface with a radar beam footprint, and means for profiling/processing the resultant radar returns in an efficient and logical fashion such as to derive radar attitude information in real time about a number of predefined axes associated with the radar which depends upon the relative dispositions of the radar and the selected surface and upon the radar beam footprint characteristics. Advantageously, a plurality of transmit beams 10,11,12 are used to image the surface and the processing arrangement has the capability of determining roll, pitch and/or yaw pointing data associated with the radar, such pointing data being determined by derivation of the attitude information and by selective input of terrain elevation data so as to take account of variations in the radar viewing geometry with terrain elevation. The inventive radar bears a definite low cost advantage over known radar designs, and retains utility for many applications, for example spaceborne and airborne applications.

A plug member adapted for insertion into a tube end seals about its periphery in response to a predetermined activation to prevent fluid flow through the tube. In one embodiment, the plug contains annular rings that expand radially outwardly in response to thermal excitation. In an alternate embodiment, a welding material is forced about the plug periphery to seal with the interior surface of a tube in response to a predetermined activation.
