摘要： The invention relates to foam structures with enhanced physical properties which can be used in the areas of packaging, athletics, water sports, and construction. In general, the structures are laminated polymer foams that include a core of a low density foam and one or more skins of relatively high density foam covering the core. The skins provide improved physical properties to the foam structures by improving the flexural strength, resistance to bending, and resulting damage from bending in the laminated foam structure while modestly increasing the weight of the laminated structure, for example. Uses of the foam structures include, but are not limited to, packaging materials, gym mats, body boards, or eaves fillers. The skin can act as a hinge to fold a die cut piece into a collapsible packaging system.

摘要： An external field activated display sheet is disclosed which comprises a plurality of hourglass shaped capsules for each pixel of an image. Each hourglass shaped capsule contains ink in one of its chambers. The ink in each hourglass shaped capsule is responsive to an external field being applied across the capsule for the movement from one chamber to the other. An opaque medial sheet blocks the visibility of the ink in the chambers under the medial sheet. Applying an external field across an hourglass shaped capsule causes the ink to be moved into the chamber above the medial sheet where it is visible. By applying an external field across selective hourglass shaped cavities, an image can be displayed.

摘要： There is disclosed a method for the preparation of a homogeneous physically stable colloidal elemental cobalt dispersion of colloidal cobalt particles having a size in the range of from about 10 Angstrom units to about 200 Angstrom units. The method comprises preparing a solution of a passive polymer in an inert solvent, and incrementally adding thereto a cobalt precursor, at a temperature at which the cobalt precursor will lose at least one ligand and become bound to the passive polymer and thermally decompose to produce elemental cobalt particles, the process being carried out in an inert atmosphere. Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal cobalt catalysts. The dispersions may also be used for the preparation of ablative optical recording media.

摘要： A thermistor temperature sensor having non-linear electrical response characteristics with temperature, a material constant, beta, that varies with temperature, and providing an output signal indicative of the temperature desired to be measured is utilized herein. A time dependent signal having a configuration that offsets the non-linear temperature dependence of the sensor output signal is generated and compared to the sensor output signal. Whenever the sensor output at least equals that of the offsetting signal, a comparator generates an output signal that, after appropriate delay, is indicative of the actual temperature. The material "constant" of the sensor is maintained substantially constant over at least a substantial range of temperatures. Additionally or alternatively, the sensor is energized in such manner as to substantially eliminate self-heating induced variations in the sensor output signal.

摘要： A system for controlling sequence and duration of the operational steps in processes such as vulcanization of a pneumatic tire is capable of operating under two basic modes or parameters. In one mode the operational steps are dictated by elapsed real time, while in the other mode, the operation can be dictated by elapsed cure equivalent factors. The desired length of each step or the cure, whether in time or cure equivalents, is set into an input program means. In the time mode, time generating circuitry provides an output proportional to elapsed time which output is displayed on a counter and electrically compared with the information in the input program means. When a match occurs, the time generating circuitry and displays are reset and the input program means directs the tire vulcanization press to perform the next sequential function. Also disclosed is circuitry which is capable of performing secondary functions such as extending the length of a step, as necessary. If it is desired to operate in the cure equivalent mode, a signal proportional to elapsed cure equivalents is developed by a cure equivalent generating circuitry which performs digital integration of the Arrhenius function. The input to cure equivalent generating circuitry can be a signal proportional to tire temperature developed by internal thermocouples or can be a signal which is directly proportional to the Arrhenius function as generated by a thermistor sensor.
摘要翻译：用于控制充气轮胎的硫化过程中的操作步骤的顺序和持续时间的系统能够在两种基本模式或参数下操作。在一种模式中，操作步骤由经过的实时指定，而在另一种模式中，操作可以由经过的固化等效因子来决定。每个步骤或固化的期望长度（无论是时间上还是固化等价物）被设置为输入程序装置。在时间模式中，时间产生电路提供与计时器上显示的输出成比例的输出，并与输入程序装置中的信息进行电气比较。当发生匹配时，时间生成电路和显示器被复位，并且输入程序意味着引导轮胎硫化机进行下一个顺序功能。还公开了能够执行次要功能的电路，例如根据需要延长台阶的长度。如果希望以固化等效模式操作，则通过执行Arrhenius功能的数字积分的固化等效产生电路来开发与经过的固化当量成比例的信号。用于固化等效发电电路的输入可以是与由内部热电偶产生的轮胎温度成比例的信号，或者可以是与由热敏电阻传感器产生的Arrhenius函数成正比的信号。
