Title: Control of pulse power amplifier rise and fall
Inventor: JENSEN OLE HEDEVANG
IPC: H04B7/005
Filed: 1990-09-06
Abstract: A pulsed power amplifier (100) for amplifying radio frequency signals. The pulsed power amplifier comprises control means (124, 126, 102) for generating control signals to the amplifier output power so as to provide an output pulse having rising and falling transitional phases, and means (112, 114, 117, 118, 122, 132, 134, 137, 138, 142) for generating a subsidiary pulse signal to be applied to the control means in order to adjust a transitional phase of the output power pulse. The generation of the subsidiary pulse may depend on a measured parameter of a previous output power pulse, such as the time taken for a preceding output power pulse to signal a predetermined output power level. Alternatively, the generation of the subsidiary pulse may depend on a parameter of the present output power pulse.  In both cases the generating means can control the magnitude of the subsidiary pulse in response to the parameter.

Patent GB-2257945-A (GB)
Title: Paper transport arrangements in printers.
Inventor: SATO TSUTOMU
IPC: B41J11/30
Filed: 1992-04-23
Abstract: A selective printer for printing upon continuous web-stock has provision for immobilising the web when the printer is not printing (e.g. as when awaiting the next printing command). As described, an electrostatographic printer for web (20) comprises a photoreceptor drum (1), paper tractor (9), and heated fixing rolls (8). During printing, the paper is transported by the pull of the fixing rolls (8), and the tractor (9) idles. When no printing is performed, the nip of the fixing rolls is opened to prevent overheating of the paper, and under these conditions the tractor (9) acts as a brake to prevent paper movement. The tractor can also feed the web (e.g. to register the web in the printing position, e.g. when a new web is loaded). Numerous detailed embodiments of manners of regulating the tractor between idling, braking and feeding are given. In some a clutch disengages a high ratio drive train for the idle motion, and reengages it (with no drive motor actuation) for the braking phase. In others positive locks are applied to the tractor shafts. It is stated that immobilisation of the paper prevents misregistry of a subsequent printing operation when the web is subject to being severed by a paper shear while the fixing rolls (8) are disengaged. <IMAGE>

The bracket (32) is preferably provided with ribs (38) to engage the bearing member (35) of the lifter bar (26). Preferably fins (40) carried by the cover (12) also engage lugs (42) carried by the base portion (11). Preferably sockets (44) formed on the cover (12) are aligned with knuckles (47) formed on the base portion (11) and together they receive hinge pins (50) therethrough so that upon pivoting of the pedal (22), the bearing member (35) of the lifter bar (26) engages the ribs (38) of the cover (12) to cause the cover (12) to rotate on the hinge pins (50) to thereby expose the open top of the base portion (11). The sockets (44) preferably have a countersunk recess (45) to receive an enlarged head (51) of the hinge pins (50). A compressible lock barb (54) on the opposite end of hinge pins (50) preferably holds hinge pins (50) in place. <IMAGE>
