    • A dimensional detector useful for determining the height of a package as it moves along a conveyor, comprising a light source and corresponding light sensors oppositely disposed across the conveyor, wherein the light is interrupted by the package before being received by the light sensors. Rapid determination of the package height is provided by grouping the light sensors into groups of contiguously disposed light sensors and a group of light sensors interspersed between the contiguously disposed light sensor groups. Included within the group having interspersed light sensors is also a group of contiguously disposed light sensors which are located at the lowest end of the dimension to be measured. According to the invention, the group of light detectors comprising the interspersed light detectors and the lowest dimensional disposed contiguous detectors is first read to determine if the package height is within the lowest dimensional disposed contiguous detector. If not, one of the remaining groups of contiguous light detectors is read, according to the signals from the interspersed light detectors. In this manner, the package height is rapidly determined often with only one group reading, but never more than two group readings.
    • 一种尺寸检测器,用于确定包装沿着传送带移动时的高度,包括光源和相对设置在横跨传送带的相应的光传感器,其中光在由光传感器接收之前被包装中断。 通过将光传感器分组成连续布置的光传感器和散布在连续布置的光传感器组之间的一组光传感器来提供包装高度的快速确定。 具有散射光传感器的组内也包括一组连续布置的光传感器,它们位于待测尺寸的最低端。 根据本发明,首先读取包括散置光检测器和最低维度设置的相邻检测器的光检测器组,以确定封装高度是否在最低维度设置的相邻检测器内。 如果不是,则根据散布的光检测器的信号来读取剩余的一组连续光检测器中的一个。 以这种方式,包装高度通常只有一组读数而不是两组读数迅速确定。

    • A system to apply a bar-code label or the like upon a product or to apply a protective laminate strip or the like upon a bar-code label or the like which is already in place upon a product. The label or the protective laminate strip first is removed from a moving carrier and applied to an applicator head which, in turn, applies the label on the product or the protective laminate strip very precisely onto the label. The relative positions of the applicator head and the label, for example, are predetermined. It remains to establish the moving forward edge of the bar-code label or the protective laminate strip to be stripped from the moving carrier so that the either can be accurately placed on the applicator head, a particularly vexing problem in view of the fact that transmissivity, usually, or reflectivity of all the films involved, typically, have closely related optical characteristics. The system discloses uses pulse-width-modulated techniques (PWM) and duty cycle which overcome inherent problems that arise from those optical characteristics, e.g., wandering of sensing circuitry over time or due to temperature, moisture and the like. Hence the high sensitivity and stability needed for such purposes are provided. The system disclosed uses digital counting techniques with their stability, particularly in the context of duty cycle. The concepts herein disclosed are framed in the context of labeling devices but are broader.
    • 将条形码标签等应用到产品上或者将保护层压条等施加到已经在产品上的条形码标签等的系统。 标签或保护性层压条首先从移动的载体上移除并施加到施用器头上,该涂抹器头将产品或保护层压条上的标签非常精确地施加到标签上。 例如,涂抹头和标签的相对位置是预定的。 仍然要建立条形码标签或保护性层压条的移动前缘,以从移动的载体剥离,以便将它们精确地放置在涂抹头上,这是一个特别令人烦恼的问题,考虑到透射率 通常或所有涉及的膜的反射率,通常具有密切相关的光学特性。 该系统公开了使用脉冲宽度调制技术(PWM)和占空比,其克服了由这些光学特性引起的固有问题,例如随着时间的流逝或由于温度,湿度等而感测电路的漂移。 因此,提供了这样的目的所需的高灵敏度和稳定性。 所公开的系统使用具有稳定性的数字计数技术,特别是在占空比的情况下。 本文公开的概念是在标注设备的上下文中框架的,但是更广泛。

    • Naphtha is isomerized using a medium-pore zeolite catalyst.Isomerization is accomplished by contacting the hydrocarbon with the medium-pore zeolite catalyst at a temperature in the range 200.degree. to 400.degree. C., preferably, at a space velocity of 0.05 to 75 v/v/hr, preferably, at a pressure at 14.7 to 1500 psig.The medium zeolite catalyst employed has a silica to alumina ratio in the range of about 5 to >30, preferably 10-20, more preferably 12-17 and a pore size of about 5.5 to 6.8 .ANG.. The preferred medium pore zeolite is a zeolite of the offretite type. The zeolite preferably has associated with it a hydrogenation component which is typically a Group VIII metal, oxide or sulphide, or mixtures thereof, preferably platinum or palladium. The preferred offretite type zeolite may be any of the readily available commercial materials and may have their SiO.sub.2 /Al.sub.2 O.sub.3 ratios enhanced by typical methods such as H-EDTA or mineral acid leaching, or similarly may be any of the specialty offretites and offretite type zeolites now being described in the patent or general literature.
