Abstract: It is known to mount a needle so that it can telescope inside a sheath, the sheath protecting the needle when it is not in use. Once used, such a needle can be returned to its sheath, but there is nothing to prevent its subsequent withdrawal from the sheath. This has several disadvantages, in particular, there is a risk from contamination if a used needle can be withdrawn from its sheath. Disclosed herein is a needle device (8) and method of use. The needle (42) moves out of and into a protective housing (10) between two operative positions, one of which causes the housing (10) to shield the needle (42). Each operative position includes releasable locking detents (60, 62) to temporarily hold the needle (42) in one of those positions, the holding force of one being less than the second. A third position beyond the one that shields the needle (42) in the housing (10) is used to permanently lock the needle (42) in the housing (10) against accidental re-use. The needle device (8) can be used with a blood collection container or a syringe drug delivery container, each container being capable of releasably mating with the device during use.

Abstract: The present invention relates to a method of bleaching cellulose pulp with ozone. 
     Ozone bleaching has been extensively studied in laboratory and pilot scale. It has been proved that at low consistencies, i.e. less than 5 %, ozone dissolves well in water and thus good transfer of substance between the ozone and the fibers in the water is achieved. On the other hand, it has been discovered that the ozone, being a gaseous substance, reacts well also directly with a fiber surface which, however, presupposes that the consistency of the suspension is over 25 %. Further, it has been discovered that in the intermediate range between said consistencies ozone cannot satisfactorily contact the fibers. However, both environmental and pumping factors determine the operation to be carried out at that particular intermediate consistency range of 5 to 25 %. 
     A characteristic feature of the method of the present invention, which avoids the disadvantages of prior art methods and permits operation at the consistency range of 5 to 25 %, is that cellulose pulp is pumped with a high-­consistency pump to a fluidizing mixer in which O₂/O₃ gas is introduced and mixed into the pulp so as to generate foam in which the fibers in the pulp and the ozone used as the bleaching agent are brought to contact with each other, and that the pulp is discharged from the mixer to a reaction vessel.

Abstract: A channel selection system for radio communication equipment which uses a control channel for interchanging control signals for connection and a plurality of data channels for interchanging data and emits an electromagnetic wave by using any one of the data channels after determining that it is idle by carrier sensing. The system rarely selects a data channel adjoining the control channel since the probability that such a data channel is registered as an idle channel is extremely low. The system, therefore, reduces the possibility of the equipment being unable to use the control channel due to the influence of power leaking from the data channel adjoining the control channel.

Abstract: Hand-operated staplers require, in particular when driving in the staples and penetrating the material to be stapled, a considerable effort, which entails disadvantages for the user. The stapler according to the invention possesses a locking and releasing mechanism which keeps the impact cutter (24) via a catch (45) temporarily in a position which is unchanging with respect to the staple (G) to be driven in and, on the other hand, brings about a sudden release of the impact cutter (24) onto the staple (G) to be driven in, and hence the actual stapling operation, in the unlocked position of the catch (45) via a spring (40) tensioned by actuating the upper part (30) of the stapler and connected to the impact cutter (24). According to the invention, after the automatic stapling operation a force peak can be used manually if a final thrust is required for a thicker stack of paper. <IMAGE>

Abstract: Control systems are used as access control, with the aim of only allowing authorised persons to have access to certain buildings or rooms. The control systems comprise data carriers (transponders) which are carried by the relevant persons and are brought into the local vicinity of a reader so that the data of the data carrier can be wirelessly transmitted to the reader. The reader forwards the received authorisation data to a central evaluating unit where these authorisation data are checked. If the authorisation data correspond to the test data, the evaluating unit effects the release of a door so that the authorised person can enter a room. In the invention, only the data carrier is programmed with the customer-specific authorisation data whilst the associated readers themselves remain unprogrammed. Instead, they are programmed by the data carrier which, for this purpose, also includes, in addition to the authorisation data, corresponding control data which are also transmitted to the reader. This makes it possible to dispense with elaborate programming of the readers. <IMAGE>

Abstract: In a level sensitive scan design (LSSD) circuit embodiment for testing the behavior of logic circuits, a mechanism is provided for generating a skewed load of data into a set of shift register scan string latches. The nature of the input scan string assures that a certain number of 0 to 1 or 1 to 0 transitions occurs as an input to the block of logic being tested. Furthermore, a mechanism for delaying by one system clock cycle time the capture of information from the logic block in a second shift register scan string provides a mechanism for testing for the occurrence of short paths and long paths while preserving testability for stuck-at faults. Furthermore, all of these advantages are achieved without impacting the traditional stuck-fault test capabilities of the level sensitive scan design methodology.
