Abstract: The automated library system contains multiple independent robots for concurrently manipulating multiple media cartridges. The library system comprises a two-dimensional array that contains media cartridge storage cells and media cartridge players. A system of rails is used to guide robotic pods through all of the locations in the array, which eliminates the need for any steering or guide mechanism on board the robotic pods, resulting in a reduction in the mass of the robotic pods. The rail system also constrains the movement of the robotic pods into horizontal and vertical movements, thereby simplifying the control algorithms for collision avoidance that are required by a typical random moveable object handling system based on horizontal, vertical and diagonal degrees of freedom. The robotic pods contain a moveable carriage that is capable of transporting robotic components, such as media cartridge pickers, bar code reading devices, and other task oriented sub-modules, in the storage library rail system.

Abstract: A disk recording/reproducing apparatus is provided with a reference-point detection capability, including a device for stopping a carriage at an originating point. A control section supplies pulses to a carriage driving portion to move a carriage on which a recording/reproducing head is mounted. When the reference position detection section detects that the carriage has reached the originating point stopping device, the number of carriage-driving pulses expended is automatically stored in a memory in the form of position information. The control section uses an adjustment disk for positioning the recording/reproduction head and storing the position data. The control section further supplies the required number of pulses to move the carriage driving section to an Nth track on the adjustment disk. When the carriage reaches the Nth track, the control section again stores the number of carriage-driving pulses expended.

Abstract: A cutting and folding apparatus receives a printed web from a printing section including a plate cylinder and produces a variety of signatures. The apparatus includes a folding cylinder having a diameter two or more times as large as that of the plate cylinder, a collecting cylinder adjacent the folding cylinder and having a diameter 1.5 times as large as that of the plate cylinder, a pin cylinder adjacent the collecting cylinder and having the same diameter as the plate cylinder, and a gripping cylinder adjacent the folding cylinder and having the same diameter as the folding cylinder. To obtain superimposed signatures, cutting knives circumferentially provided on the folding cylinder transversely sever, in cooperation with holding members on the collecting cylinder, the running web supplied therebetween. The severed sheets are held by the holding members and superimposed one over the other, two superimposed sheets being successively transferred to the pin cylinder for delivery.

Abstract: Apparatus for screen printing on cylindrical surfaces in which the driving force is created by rotation of the object to be imprinted. The force is transmitted by a belt mechanism and by direct friction between the object being printed and the stencil frame. The stencil frame is mounted for linear movement with minimum yawing and with freedom for vertical movement as required. The printer has particular advantage when the object being printed has a large moment of inertia or is circumferentially unbalanced.

Abstract: An apparatus for the printing industry relating to the folding of printed webs. More particularly the invention concerns the means for uniformly gripping the full width of a wide printed web at intermittent periods to obtain accurate folding. The gripping apparatus is opened and closed by an endwise shifting of an actuator. A cam at one end causes the actuating member to shift one way and then a cam at the other end shifts the actuating member in the other direction. The actuator member is itself cammed to move fore and aft as it moves endwise and imparts only its fore and aft movement to a movable gripper jaw. There is no arcuate swinging of a rod such as in previous devices and hence there are no adverse effects of torque or twisting occuring during the gripping operation. The present construction permits uniform gripping of the full width of the printed web without any tendency of the operator member to twist and irregularly grip the web.
