Abstract: The machine intended for printing two lines of characters of different color (8, 9) on self-adhesive labels comprises two printheads mounted in a rocking housing (7).This housing comprises two holding elements (14, 16) engaged in two guide slots (17, 19), and a drive finger (15) engaged in a fork (18) of a drive lever (13) actuated by a trigger (3).The slots have shapes which are so adapted that upon the printing impact of the two lines of characters on a print platen (12) the rocking of the housing is transformed into a translation which is not affected by the play and movements of the drive lever and is oriented towards the print platen.Two inking rollers of different color (22, 23) are mounted in a common retractable support (24) by means of a mechanism (26, 29, 30) intended to assure the selective inking of the two lines of characters.

Abstract: The machine is intended for the printing of selected characters on self-adhesive labels (5) forming a continuous series borne by a support strip (8).The inner circuit of this strip passes via a loop defined by an edge (11) at the level of which each label (5), after printing, is advanced by a step corresponding to its length, is separated from the support strip, and is directed below a pressure roller (12) in order to be glued by pressure onto an article to be labeled.In order to prevent the falling of the printed label before its gluing and in order to present it flat below the pressure roller (12) there are provided a cambering device which comprises two guides (20, 21) between which the label is stiffened by cambering in the direction of its displacement and the pressure roller itself, under which the edges of the label which have been raised by the cambering are brought downward.

Abstract: A method and apparatus is proposed for the H and V-contour correction of a digitized video signal wherein after deriving a digital correction signal, both the main video signal and the correction signal are D/A converted. The H and V-detail signals are then derived from the analogue correction signal, are combined with a contour correction signal and are added in a suitable manner to the main video signal.

Abstract: Substituted 4-phenoxy-phenols are prepared by adding the corresponding anilines in liquid or molten state together with aqueous sodium nitrite solution in equimolar amounts to excess HCl and introducing the diazonium chloride solution obtained into a boiling mixture of about half-concentrated H.sub.2 SO.sub.4 and an aromatic hydrocarbon.

Abstract: A hand appliance for issuing or applying self-adhering labels which are stuck on a carrier strip is disclosed. The appliance has a feeding mechanism which withdraws the carrier strip to feed one label at a time. The feeding mechanism has a winding core on to which the carrier strip is wound and which is rotatable about a journal fixed at one end to a housing wall. The winding core is held for axial displacement on a boss which drives the winding core by means of a projection engaging a groove extending obliquely of a surface line of the boss such that the boss shifts the winding core under the tension of the carrier strip in the direction of the wall of the housing on which the journal is fixed to thereby maintain said winding core within the appliance when in operation and facilitate its removal when desired.

Abstract: A hand-held labeller for printing and/or applying self-adhesive labels which adhere as a strip or separately at equal distances on a carrier strip, the apparatus comprising a frame; a supply member mounted with respect to the frame for mounting the carrier strip and labels; a label separation member mounted with respect to the frame; a feed wheel or winding drum mounted with respect to the frame; means for guiding the carrier strip from the supply member by the label separation member and then to the feed wheel; a hand lever so pivotally mounted with respect to the frame that the lever may be pivoted by an operator's hand as the labeller is being held in the hand of an operator; coupling means for coupling the hand lever to the feed wheel to operate the feed wheel each time the hand lever is pivoted and thus advance the carrier strip from the supply member so that the labels are successively separated from the carrier strip at the label separation member and the carrier strip is incrementally wound upon the f

Abstract: A hand-held labelling apparatus for printing, dispensing and applying self-adhering labels, having a housing provided with a handle and having two side walls consisting of sheet metal and held in spaced relation.Each side wall of the said housing comprises two parallel and free edges which are opposite one another.Casing or sheathing walls consisting of synthetic plastics are capable of being pushed over the outsides of each side wall. The said casing walls comprise flanges which engage over the free edges of the side walls.

Abstract: For the line-by-line optical scanning of a film as it passes at high speed through a scanning region, particularly to obtain television image signals, a light source directs light to a sensor. To reduce friction of the film adjacent the scanning region, two rollers or endless belts support the film at positions on the film outside the film frames. These rollers or belts replace the previously usual stationary film guide shoes adjacent the film gate. Lateral guidance of the film can be provided by rollers.

Abstract: A method and a circuit for the additive and multiplicative spurious signal compensation of a video signal are proposed. For additive spurious signal compensation, a signal is derived from the "black level" signal, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is subtracted from the video signal. For multiplicative spurious signal compensation, a signal is derived from the "white level" signal, its reciprocal value is formed, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is multiplied with the video signal. A three channel system for color television signals is disclosed.

Abstract: In a printing device such as labelling appliance having a printing table, a printer movably mounted with respect to the table, an ink carrier which inks printing types carried by the printer, an inking pivot member which holds the ink carrier at the free end thereof and which is pivotable against the force of a return spring, the pivot member being adapted to be pivoted out of the path of movement of the printer when the printer moves toward the printing table, the improvement comprising the ink carrier being a resilient transfer roller which is freely rotatably mounted with respect to the inking pivot member and including a dense, readily wettable surface, an inking roller that stores ink, the inking roller being made of a finely porous material, an inking roller support having side walls where each wall has an open-ended bearing recess which opens toward the transfer roller for freely rotatably supporting the inking roller about an axis parallel to the axis of rotation of the transfer roller, the inking rol

Abstract: A scrap compactor has a generally parallelepipedal elongated chamber. The top wall of the chamber may be pivoted down to partially crush the scrap, and a lower portion of one of the side walls of the chamber may be pivoted inward to similarly precompress the scrap. After swinging-in of the lower portion of the one wall this wall is swung outwardly and the opposite wall is moved in while remaining parallel to the other wall. Thereafter the fully compacted scrap may be pushed out an outlet hole in one end of the press.

Abstract: In an apparatus for printing and dispensing labels carried in a label ribbon of indeterminate length, a hand lever is held in a rest position by a return spring and a printing device is coupled with the hand lever for movement toward a label, located on a printing table, upon depression of the hand lever and away from the printing table upon release of the hand lever. A transport mechanism is coupled with the hand lever for advancing the label ribbon by a distance equal to the label spacing on the ribbon each time the hand lever is actuated. A printing device is carried at the free end of a further lever movable in the same plane as the hand lever and normally held stationary by a pawl, the other end of the further lever being coupled with the hand lever through a further spring extending between the hand lever and the further lever.

Abstract: A pipe cutting and/or welding device has a chuck for rotating the pipe with the chuck jaws connected with an activating device provided with torque limiting means. The torque limiting means has an adjusting device for switching from a low torque value for the clamping of the pipe to a high torque value for releasing the pipe.
