IPC: B41J2/17

Abstract: To flush ink out of the ink gun 15 of an ink jet printer, it is connected to a suction source 23 (normally used for gutter suction) through a purge line 33, purge valve 35 and gutter valve 27, while the ink feed line 13 is connected to the solvent reservoir 17 through a feed valve 11 and a flush valve 37. This draws solvent from the solvent reservoir 29 into the feed line 13 and the ink gun 15. Then, the purge line 33 is isolated from the suction device 23, and the feed valve 11 connects the feed line 13 to a supply of ink pressurised by ink pump 5. The pressurised ink is driven into the feed line 13, driving some of the solvent already in the feed line and the ink gun 15 out through the nozzle of the ink gun 15. The ink flow is then stopped before fresh ink reaches the ink gun 15. This avoids ink drying in the ink gun 15, blocking the nozzle, while the jet is not running. 
     By delivering solvent along the ink feed line 13, and using the suction device 23 and the ink pump 5 to drive the solvent, instead of providing a solvent pump   and a solvent line, the complexity, bulk and heat generation of the ink system are minimised.

Abstract: In a token ring transmission system, token loss causes selection of a leader terminal, which issues a new token. The leader terminal is chosen by selecting and storing a leadership selection reference value and then generating a succession of terminal identification signals (NID) and transferring them on the token ring transmission system. Each terminal receives the succession of signals and iteratively compares the terminal identification signals (NID) sequentially with the leadership reference signal. Each time a terminal identification signal (NID) exceeds the magnitude of the leadership reference signal, the leadership reference value is replaced with the value of the terminal identification signal. The first terminal detecting equality of a terminal identification signal (NID) with its leadership selection reference signal assumes leadership and issues a token.

Abstract: The invention relates to an unloading system for discharging dredged soil from a dredger, preferably a sand rinsing system for sand rinsing, of the sand dredged by a suction dredger, by a landside rinsing pipeline, comprising a dredger with a dredged soil space and, connected thereto, a delivery pipeline, a landside rinsing pipeline and at least one pump for pumping the dredged soil through the delivery pipeline and the landside rinsing pipeline. The aim of the invention is to indicate an unloading system or pipeline guide of the type stated in the introduction, which guide makes the unloading process of the dredger into a rinsing pipeline easier, in particular with regard to lower personnel expenditure. The aim is achieved according to the invention by an unloading system which is characterised by a float, on which the seaside end of the rinsing pipeline is arranged, by a transfer pipeline which can be connected to the delivery pipeline of the dredger, by a device for moving, in particular bringing out, the transfer pipeline, and by at least one element which makes possible a positioning of the free end of the transfer pipeline in relation to the seaside end of the rinsing pipeline, which is arranged on the float. <IMAGE>

Abstract: An apparatus for generating test signals, preferably for use in an integrated circuit tester, comprises a sequencer (23), a Vector Memory (24) and a Waveform Memory (27). The Vector Memory (24) is addressed by the sequencer (23) and contains coded waveform information, which is, in turn, decoded into control information by the Waveform Memory (27). For this purpose, the data outputs (26) of the Vector Memory (24) control the address inputs of the Waveform Memory (27). 
     The data outputs (32-35) of the Waveform Memory (27) control circuitry like a formatter (28) or a comparator (30) which link the waveform information with timing information from one or more edge generators (36). The formatters (28), comparators (30) etc. are, in turn, in connection with a device under test. 
     The present apparatus provides full flexibility in the generation of formats and waveforms and, in particular, timing and format changes "on the fly", i.e. without additional delay. Flexibility may be increased if the Waveform Memory (27) is reprogammable.

Abstract: The invention relates to a method of applying an orthodontic aid (4) to at least one tooth in a row of teeth. A cast (1) of the row of teeth is made by means of moulding and counter-moulding. The aid is temporarily secured to the cast in the desired position. A deformable layer (6a) of material is applied to the cast with aid, and this layer is deformed to conform to the shape of the cast with aid and thus a mould (6) is formed. The mould with aid is positioned on the row of teeth and the bonding agent applied for securing the aid is allowed to harden in a controlled manner. Then the mould is removed, and the aid remains behind, secured to the row of teeth by means of the bonding agent. According to the invention prior to placing the mould with the aid on the row of teeth, an adhesive layer is applied to at least a part of the surface of the mould, that is brought into contact with the row of teeth. This adhesive layer (6b) has weaker adhesive strength than the bonding agent for securing the aid to the row of teeth. When the mould is placed on the row of teeth, it is temporarily retained in that position by means of the adhesive layer. The invention further relates to a mould with an adhesive layer for use in this method.

Abstract: A parenteral device having a body slidably supporting a hollow needle. The needle is slidable between a first position in which it is completely retracted within the body and a second position wherein a portion of the needle projects outside of the body. The body further houses a chamber isolated from the needle when the needle is in the first position. Movement of the needle into the second position causes an end of the needle to pierce a wall of the chamber thereby establishing communication between the chamber and needle.
