Abstract: A method of printing a succession of images on to an elongate web, in at least two colors, comprises feeding the web past the first and second rotating printing cylinders 10 and 11, the first print cylinder applying a first color and the second print cylinder applying a second color, and periodically interrupting the movement of the web past the print cylinders, the length of the interruptions controlling the repeat distance, and the interruptions of the movement of the web past the second cylinder being controlled in dependence upon the images being produced by the preceding print cylinder. The web may be driven by means of a servo motor such that the extent to which the web moves while the motor accelerates to and/or decelerates from, its normal running speed is accurately predetermined.

The insert has a very smooth surface and is shaped to provide substantial hose contact area. The guide ring substantially extends the useful life of the rubberoid hydraulic hoses widely used on such equipment.

Abstract: The invention relates to the art field of rotary printing machines, and concerns a doctor blade clamp device in the form of a bar with a longitudinal chase that accommodates a pressure plate; the plate is urged against the blade by pressure applied through a reservoir embodied as a hollow flexible sheath, likewise accommodated by the chase, which connects with a supply of pressurized fluid and is made to expand by the operation of a suitable valve.

Abstract: A flexible printing plate clamping assembly utilizes a printing plate clamping device disposed in a groove in a plate cylinder. A plurality of elbow lever assemblies are used to move a clamping bar between plate clamping and unclamping position. These elbow lever assemblies have pneumatic devices and counteracting springs to place them in either clamping or unclamping positions.

Abstract: An ankle support prevents damage to a person's ankle by preventing severe lateral bending of the ankle. A support bar is pivotally attached to a high-top shoe, with the upper end of the bar well above the ankle and the lower end of the bar just below the foot. The upper end of the bar is fixed about centrally of the leg, while the lower end of the bar is fixed just forward of the heel. This results in having the bar pass along the front portion of the ankle. Both ends of the support bar can move somewhat at their connection points, so normal foot movement is not restricted while severe lateral motion is prevented. One aspect of the ankle support includes means for automatically adjusting the effective length of the ankle support between the attachment location above the ankle and the attachment location below the ankle.

Abstract: A printer comprising a port for feeding continuous paper therethrough, a port for feeding cut paper therethrough and a port for feeding paper manually therethrough at the front of a casing of the printer.

Abstract: A printer stand comprises a support base for holding a rear-ejection printer and a paper catcher mounted to the rear of said printer and extending rearwardly and upwardly therefrom. The catcher comprises a flat backer panel having bent-up side flanges and having a bent-up lower ledge for supporting the lower edge of a packet of sheets of paper resting against the backer panel. The catcher is mounted to the base for easy removal by providing a forwardly and downwardly extending slot at the rear of each side wall of the support base, into and out of which the panel can readily be slid; the side flanges are preferably spaced apart by only slightly more than the distance between the outer sides of the side walls, and the ledge is preferably at about right angles to the packer panel. The system provides stable support of the packet of sheets, is easily assembled and disassembled, and is inexpensively made from a single metal sheet by bending up the side flanges and the ledge.

Abstract: To permit selective operation of two printing couples (1, 2, 4, 5) for printing, on a continuous web (7) respectively double-image prime printing (FIG. 1), single-image prime printing (FIGS. 3, 5), while permitting flying plate changes of one of the plates of a disengaged printing couple, or prime and verso printing (FIG. 7), two impression cylinders are provided, engageable with the blanket cylinders of the respective printing couples, the impression cylinders being spaced from each other by a gap sufficient to permit passage of the web therebtween when the system operates in the prime-and-verso printing mode, with a gap sufficient so that freshly printed subject matter will not be smeared by contact with the respective impression cylinders.

Abstract: A tooth point for earth working, particularly ripping, which includes a relatively elongated body having rearwardly projecting tongue and recess means which cooperate with complementary tongue and recess means on a ripper shank protector.

Abstract: The invention is directed to an apparatus for recording image information on both sides of recording sheets which, lying against a partial circumference of a print roller are conducted past an image recording unit. A format of the inventive apparatus which is particularly simple in structural terms is achieved in that a sheet seating surface approaches the underside of the print roller upon formation of a sheet draw-in gap which lies preceding the image recording unit as seen in the rotational sense of the print roller and in that a sheet guidance surface forming a sheet acceptance gap together with the print roller and following the image recording unit as seen in the rotational sense of the print roller is arranged across the print roller and approaches the sheet seating surface at an acute angle.

Abstract: A device and method for installing an adhesive-backed printing blanket on a cylinder is provided. The printing blanket has an adhesive backing for holding it on the cylinder and a leading edge substantially perpendicular to the edge of the blanket. The device comprises an angle bar having a generally orthogonal pair of leg forming an inside corner therebetween for receiving the leading edge of the printing blanket to be contiguous therewith. A first one of the legs has an inside surface being an adherend of limited adhesion, the periphery of the adhesive backing adjacent the leading edge being removably adherable thereto. The first leg also has an outside surface formed to be axially aligning with the cylinder when placed thereon. As a result, the leading edge of the printing blanket is held squarely in place on the angle bar while the printing blanket is wrapped evenly around the cylinder.

Abstract: A material handling apparatus connected to a prime mover having first and second jaws, the first jaw connected and configured to approximate a grading blade for a bulldozer, and the second jaw connected to the first jaw in one of two orientations, 180 degrees apart and about vertical axis. The jaws also have open and closed positions, defining four extreme positions. The combined first and second jaws define either a bucket, or when the second jaw is extended away from the grader blade a clam shell type bucket, or a pincer type grappler.

Abstract: A paper feeding apparatus for the printer having an intermittent mechanism between a driving motor and both a paper feed roller and a platen. The intermittent mechanism allows both the platen and the paper feed roller to rotate simultaneously and also allows only the platen to rotate while the paper feed roller is suspended, so that a sheet of printing paper is set straight along the platen. When the rotational direction of the driving motor is reversed to reverse that of the platen, the driving motor stops rotating for a limited period. Under such conditions the sheet is fed properly in response to the rotation of the platen, being free from the inertia force of the sheet and from the platen's vibration.

Abstract: A mounting device and method for positioning a printing plate on a press cylinder utilizes a transparent planar surface having a grid thereon. A cylinder can be lowered into the cradle and adhesively retain a flexible printing plate which has been alinged on the grid. The method employed provides an efficient time saving and accurate mounting process.

Abstract: A membrane keyboard has two spaced flexible membranes (1 and 2) carrying contact pad assemblies. Acoustic pads (15) of expanding ink are printed on the top surface of the upper membrane (2) between the contact pads (4) and the key buttons used to operate the contact switches formed by the pairs of opposed contact pads, thus reducing the acoustic noise and improving the contact bounce characteristic.Optionally, printed expanding ink is also used to form the spacer (5) between the membranes (1 and 2).
