Abstract: A retractable blade knife having a self-sharpening facility which can be selectively rendered inoperable. The sharpener is spring biased in an upward direction so as to be urged into engagement with the cutting edge of a knife blade, and manually operable release means is provided to permit the sharpener to be held in an inoperable position. An assembly of which the sharpener forms part also functions as stop means which positively prevents movement of the knife blade into its extended position. Such extension is possible only upon operation of the release means, but that is only necessary during initial outward movement of the knife blade. The sharpener is arranged to sharpen the cutting edge of the blade up to the tip of the blade. Positive locking means is provided to prevent inward movement of the blade when working under load in the extended position.

Abstract: The disclosure relates to a method of shrink film wrapping one or more objects (12) in one or more rows. The objects are caused to be surrounded by two film webs (1, 4), which are sealed together by means of a sealing jaw (14). The objects (12) are moved in towards the two film webs (1, 4) by means of a pusher which, on its completion of the infeed movement stroke, stretches the two film webs (1, 4) in that the film webs are fixedly retained by each one of a hose brake (7, 8). When the sealing jaw (14) executes its downward stroke for completely shrouding the films (1, 4) around the objects (12), the sealing jaw (14) finally stretches the upper film (1). The film (1, 4) projecting outside the objects (12) is shrunk by means of hot air nozzles directed towards the objects (12). <IMAGE>

Abstract: A process for the production of dinitrogen pentoxide (N2O5) in an organic solvent consists of dividing off a minor proportion (31) of the anolyte stream (11) of an electrolytic cell (2) which is set up to generate N2O5 and of cooling that portion and/or adding to the portion a quantity of N2O4, such that two phases are formed. The phases are separated (34) and the light (upper) N2O4 phase is then stripped of dissolved N2O5 the N2O5 being redissolved in an organic solvent. Conveniently, the N2O4 phase is chilled (at 41) to produce crystalline N2O5 which is dissolved in an organic solvent such as dichloromethane. All effluent streams may be recycled with addition only of fresh concentrated nitric acid and fresh N2O4 to make the process capable of continuous operation. <IMAGE>

Abstract: A multiple mode, personal, wireless communications system exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. The system uses handsets (32) which automatically switch between a standard cellular radiotelephone mode of operation (1901) and an enhanced cordless mode (1420) when the handsets (32) are within range of pico cells (26) that are interconnected to the public switched telephone network (20). Each pico cell is controlled via a framework of overlay cells (10b) that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally dynamic, non-capturing, frequency agile, multi-purpose base station (26) provided at customer-selected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets (32) and using low power operation that achieves limited coverage. Each pico cell reduces traffic on the standard cellular radiotelephone network by independently handling registered handsets (32). An alternate line option module (22) provides wireless local interconnect capability to selectively route call traffic between land lines (24) and the standard cellular radiotelephone network. Service control units (12) and host stations (17) facilitate wireless activation and control of each pico cell and handset (32) via the overlay cell framework.
