Title: Printing sleeves
IPC: B41F5/24
Filed: 1977-01-07
Abstract: For fitting a printing sleeve in a printing roll the outer surface of the roll core and preferably the inner surface of the sleeve are made at least partly tapered the sleeve is slightly undersize diametrically. Remote from the ends of the core are orifices whereby gas under pressure may be blown radially outwardly from the core. The tapers allow the sleeve to be passed freely along the core until it jams up against an increased diameter portion of the tapered outer surface of the roll, at which time it covers the orifices. Gas is then blown from the orifices to expand the sleeve which can then be moved into its working position on the core. A sleeve specially suitable for this treatment is made by laying-up a seamless GRP layer on a former which is undersize for the designed core and either curing a rubber layer in situ onto the layer, or adhesively securing a flexible plate to a true cylindrical outer surface of the GRP layer.

Title: Television camera and pick-up tube having stripes for improved resolution and linearity
IPC: H01J29/45
Filed: 1977-07-04
Abstract: A black-white or color television camera has a pick-up tube having a signal electrode comprising separate strips. Before a line scanning operation to be performed by an electron beam takes place, the signal electrode strips are coupled to a reference potential. After the line scan, the strips which are coupled separately to parallel inputs of a switching circuit which is provided with switches coupled to the parallel inputs, are coupled for supplying video information. This results in a separation between electron beam scanning and picture signal supply by the pick-up tube, which has the advantage that the beam scanning does not affect the picture quality in the direction of line scan. Furthermore, the construction with strips yield an improved signal-to-noise ratio. The switching circuit may, possibly together with a shift register, be integrated in a semiconductor body, which is provided near the signal electrode in the pick-up tube or outside the pick-tube.

Patent ES-465395-A1 (ES)
Title: Apparatus for control of a continuously variable belt drive for operating a vehicle
IPC: B60W10/10
Filed: 1977-12-23
Abstract: A drive motor that may be an internal combustion engine or an electric motor is operated at substantially constant speed or, in the case of an internal combustion engine, at one of two substantially constant speeds. The speed of travel of the vehicle under various load conditions is varied by a drive control pedal operating a transducer that furnishes one input to a signal processor while a torque transducer in the engine drive shaft provides a second input to the processor. The processor output controls the positioning device that determines the transmission ratio of a continuously variable belt drive transmission by pressing together the halves of one pulley of the belt drive while separating the halves of the other pulley, varying their effective diameter with respect to the wedge-shaped belt in opposite directions. When an internal combustion engine is used as the drive motor, the engine speed can be selectably the maximum-torque speed or the maximum-power speed and the selection can be made automatic by means of limit switches operating at the respective extremes of the variable belt drive control range. When an electric motor is used as the drive motor, a compound-wound motor is operated at a speed in the transition range between behavior mainly as a series-wound motor and behavior mainly as a shunt-wound motor.
