Abstract:
A deflector of a sheet distributing mechanism is positioned at selected stations in response to the passage of sheets past the deflector. A manually programmed crossbar switch determines the preselected numbers of sheets to be distributed to any one of several stations. A sheet stepping switch and a station stepping switch join the programmed crossbars of the crossbar switch when the programmed number of sheets have been received at the selected station so as to index the deflector to the next station. The number of sheets and the number of stations programmed may be varied, stations may be skipped or the device may operate as a collator by distributing a single station at a time to one or more of the sheets. An anticipating device is employed on the station stepping switch to permit smooth operation of the distributing mechanism when several stations are to be skipped.
Abstract:
A composite glass fiber cable is disclosed having a negative linear coefficient of thermal expansion which is controllable by variation of the twist of helically plied glass roving to substantially zero change in length over a wide variation in environmental temperatures under varying load conditions.
Abstract:
A sorting device which receives and path and in-face-to-face proximity sheets at preselected positions includes a distributor for receiving and distributing the sheets for reception by a receiver and sheet retaining means cooperating with the conveyor means of the distributor for holding the moving sheets against the conveyor while being conveyed to the position where the sheets are deflected into the receiver. The sheet retaining means includes flexible strands connected between the upper and lower ends of the conveyor path and in-face1to-face proximity with the conveyor means to hold sheets against the conveyor means while being moved to the position from which the sheets are deflected, and guide means for each of the flexible strands secured to a deflector assembly to divert the strands laterally outwardly from a point before deflection of the moving sheets to avoid interference of the strands with the moving sheets being deflected into the receiver.
Abstract:
A sheet collating device having a collator distributor for receiving sheets and distributing the sheets at preselected vertical positions for reception by a vertical column of bins. The sheet distributor has a perforated tape conveyor system with a vertical course located in front of the column of bins. The conveyor tape passes over a vacuum plenum which serves to hold the sheets to the moving tape until they are deflected. A deflector mechanism is mounted for vertical travel up and down the vertical course of the conveyor with its position being controlled by an electrical control system so as to cycle through a set of preselected vertically spaced positions. Extensible tape members are connected at one end to the deflector so as to move therewith and to overly the moving sheet to aid in retaining the sheet against the conveyor. Stationary vertical backup means are provided in back of the sheet which cooperate with the extensible tapes in maintaining the sheet properly disposed until it reaches the position of deflection. The device may also include bypass conveyor means for moving sheets onto an adjacent collating device placed in tandem. The bin assembly is carried by the same frame and cabinet which mounts the distributor mechanism and is mounted so as to be easily removed from the cabinet. Access is afforded to the shelves from one side of the cabinet to facilitate removal of the collated sheets.
Abstract:
The randomly programmed sequential sheet sorting machine operates to sequentially fill a plurality of sheet receiving trays in a sorter assembly with a number of sheets programmed for selected trays. An address for each selected tray and the number of sheets for the tray are entered in random manner in a computer memory and the memory sequentially provides tray address and corresponding sheet information in order of tray arrangement. In the event of copy jamming or copy count error, the machine is precluded from automatically continuing subsequent programmed operation until correction is made.
Abstract:
A coreless glass fiber cable is made of a plurality of individual substantially untwisted glass fiber rovings twisted together. Certain of the rovings are impregnated with one component of an elastomeric resin with the remainder of the rovings impregnated with the second component of the elastomeric resin. The impregnated rovings are spirally twisted together in the same direction at substantially the same helical angle, the two components of the elastomeric resin impregnating the rovings mixing with each other at the junction of the intertwining of the rovings to form a cured elastomer spacing the glass fiber rovings and filaments making up the rovings from each other. The layed up glass fiber cable is fed back on itself and subsequent layers of impregnated rovings plied together over the initial layers. The subsequently applied layers are applied at the same helical angle as the initial layer. The cable, although useful for other purposes, is particularly useful in the manufacture of endless track for track vehicles, the endless track comprising a plurality of individual track sections strung along a cable of the type mentioned.
