摘要： There is provided an improved automatic recirculating duplicator adapted for duplicating from a master or plate selectively onto one or both sides of paper sheets. It is characterized by a single printing couple. Sheets are fed from a paper table to a printing nip between a printing cylinder and an impression cylinder for printing on the first side and, through operation of a controlled gripping and stripping apparatus, the sheets are turned about the impression cylinder for collection with the printed sides down on a paper tray. The paper tray is then shifted to the feeding location normally occupied by the paper table, and the gripping and stripping apparatus is reset for feeding the sheets, now printed on both sides, directly to an exterior receiver. When it is desired to print sheets on one side only, the mechanism is set for feeding sheets from the paper table, but manual controls permit resetting the gripping and stripping mechanism to feed sheets directly to the receiver instead of inverting them and sending them to the paper tray.
摘要翻译：提供了一种改进的自动再循环复印机，其适于从主板或板选择性地复印到纸张的一侧或两侧。它的特点是单打印夫妇。纸张从纸台进给到印刷滚筒和压印滚筒之间的印刷辊隙，用于在第一面上进行印刷，并且通过操作受控的夹紧和剥离装置，片材围绕压印滚筒转动以便与印刷侧面放在纸盘上。然后将纸盘移动到通常由纸台占据的进给位置，并且夹紧和剥离装置被复位，以将印刷在两侧的纸张直接送到外部接收器。当仅需要在一侧打印纸张时，该机构被设置用于从纸张台进纸，但是手动控制允许复位夹持和剥离机构以将纸张直接馈送到接收器而不是倒转它们并将其发送到纸盘。

摘要： A duplicator is provided having a printing couple for printing on one face of a copy sheet and a collator for collating the copy sheets as they issue from the printing couple, the paper feed paths of the printing couple and the collator being arranged substantially normal to each other. The duplicator also includes special sheet handling means for passing the copy sheet from the printing couple to the collator and also inverting the sheet. The copy sheet is advanced in a first path and direction away from the printing couple and is advanced in a second path substantially normal to the first path in a second direction towards the collator. The sheet handling means comprises a sheet turn-over device positioned to intersect the copy sheet paths for receiving and progressively inverting the copy sheet as it is advanced in the first path and simultaneously directing the sheet from the first to the second path.

摘要： Apparatus which automates the collection of motor temperature, flux and shaft current data for proactive motor maintenance. Motor speed is determined by an analysis of the flux frequency spectrum, and motor load is determined based on speed, from which a normalized thermal parameter is then determined. From a spectrum analysis of magnetic flux signals a set of peaks each characterized by a frequency and an amplitude is found, and a subset of peaks is identified in accordance with predetermined identity criteria for purposes of comparison. Temperature, magnetic flux and shaft current data are trended to provide early indications of degradation, as well as for recognizing faults.

摘要： A blanket cleaning apparatus is provided for cleaning ink from a blanket cylinder of a rotary offset duplicating machine. The apparatus comprises a cleaning roller for contact with the blanket cylinder, a wiper roller and a metering roller in contact with each other and with the cleaning roller, and a wringer roller in interfering relation with the wiper roller at the zone of contact to effect deformation of the peripheral surface of the wiper roller. A cleaning fluid is supplied to the wringer roller which transfers the fluid to the wiper roller and meters the amount of fluid carried by the wiper roller to the cleaning roller for cleaning the blanket cylinder. The cleaning and the wiper rollers are driven at surface speeds differing from the surface speeds of the blanket cylinder and the cleaning roller respectively, such that the cleaning roller cleans the blanket cylinder with a scrubbing action in a minimum number of revolutions of the blanket cylinder, and the wringer roller maintains the wiper roller clean of ink and contaminated cleaning fluid for long periods without requiring cleaning maintenance of the apparatus.

摘要： An improved paper handling system includes a pair of work units which sequentially work on opposite sides of a sheet with the same edge of the sheet leading. An inverter between the two work units is effective to invert the sheet in such a manner that the edge of the sheet which leads during passage of the sheet through the first work unit will also lead as the sheet passes through the second work unit. A sheet which has been worked on, first side up, by the first work unit will also lead as the sheet passes through the second work unit. A sheet which has been worked on, first side up, by the first work unit with a head edge of the sheet leading is moved by a first conveyor along a first path into engagement with a stop member which engages the head edge of the sheet to arrest it at a first readiness position. A pusher then engages a side edge of the sheet and pushes it sidewardly. The turnover mechanism is effective to move the sheet sidewardly along a generally U-shaped path into engagement with a stop to register the sheet at a second readiness position relative to the second work unit. A second conveyor is then effective to move the sheet into the second work unit with the head edge of the sheet leading and a second side of the sheet facing upwardly.

摘要： A gunstock incorporating one or more storage magazines for temporarily storing and retaining ammunition for easy access, the ammunition having a generally flat or recessed nose such as found for example in shotgun shells. The magazine has a port allowing insertion and removal of the shell and a biasing means whereby a single or multiple shells is pushed forward such that the recessed nose abuts against a projection member. The junction between the magazine bore and the magazine port is configured as a cornered edge on the interior side, and the distance from the cornered edge to the projection member is determined as a function of the ammunition to be stored, such that with a shell disposed against the projection member, the cornered edge will be located at least halfway up the annular brass base of the shell. In addition, the gunstock is provided with a pistol grip, which provides an improved means for grasping and holding the weapon while ammunition is being removed and loaded.

摘要： A foursquare dual polarized moderately wide bandwidth antenna radiating element is provided which, due to its small size and low frequency response, is well suited to array applications. The foursquare element comprises a printed metalization on a low-loss substrate suspended over a ground plane reflector. Dual linear (i.e., horizontal and vertical), as well as circular and elliptical polarizations of any orientation may be produced with the inventive foursquare element. Further, an array of such elements can be modulated to produce a highly directive beam which can be scanned by adjusting the relative phase of the elements. Operation of the array is enhanced because the individual foursquare elements are small as compared to conventional array element having comparable frequency response. The small size allows for closer spacing of the individual elements which facilitates scanning. Additionally, a family of trimmed foursquare antennas is provided which offer improved performance and size considerations.
摘要翻译：提供了四平方双极化中宽带宽天线辐射元件，由于其小尺寸和低频响应，非常适合阵列应用。四方形元件包括在悬挂在接地平面反射器上的低损耗衬底上的印刷金属化。可以利用本发明的四方形元件来产生双线性（即，水平和垂直）以及任何方位的圆形和椭圆偏振。此外，可以调制这种元件的阵列以产生可以通过调节元件的相对相位来扫描的高度指向的光束。与具有可比较的频率响应的常规阵列元件相比，单个四方形元件较小，从而增强阵列的操作。小尺寸允许各个元件的更紧密的间隔，这便于扫描。另外，提供了一系列修剪的四方天线，其提供改进的性能和尺寸考虑。
