摘要： A colorless liquid ink is provided which yields a distinctive marking color on exposure to normal environmental conditions of temperature and pressure as when used for writing on a sheet of plain paper. This ink may be encapsulated to give pressure-rupturable microcapsules. Autogenous, pressure-sensitive record materials are provided by incorporation of such microcapsules in or on sheets of paper for use singly or in manifold duplicating systems which respond to printing-pressures applied by un-inked printing members.

摘要： A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material. The polymerization includes a reaction between urea and formaldehyde in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydrocarbon polyelectrolyte material dissolved in the vehicle. Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the urea/formaldehyde reaction product without further dilution of the manufacturing vehicle. The negatively-charged polyelectrolyte material is required and has an apparent effect of controllng or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of microcapsules in concentrations of capsule to capsule manufacturing vehicle higher than previously possible.

摘要： A novel record material is disclosed comprising a substrate bearing microcapsules having nonmeltable walls. The microcapsules contain a chromogen or developer and a photosensitive composition internal thereof, said microcapsules undergoing a change in viscosity upon exposure to actinic radiation. The walls of the microcapsules have an elongation of not more than 1%, and the record material is resistant to heat, measured by not producing any substantial color when placed in a 150.degree. C. oven for one minute. Surprisingly, the record material however is capable of forming a color upon application to the record material of a point source energy input comprising a .DELTA.T of at least 115.degree. C. per one millisecond.

摘要： Radio frequency (RF) shields used with magnetic resonance imaging (MRI) apparatus may experience gradient field induced eddy currents and RF field induced eddy currents. These eddy currents can cause the RF shield to heat up at an undesirable rate. RF shields are designed to have a desired degree of RF shielding and a desired heating attribute. Design goals for RF shields include gradient field transparency and RF field opacity, both of which can be influenced by eddy currents. Example methods identify a gradient field that will induce eddy currents and identify an RF field that will induce eddy currents. If a region on the RF shield is identified where the desired heating attribute will not be achieved, then a pattern of axial cuts and azimuthal cuts can be made in the RF shield to reduce gradient eddy current heating in the RF shield while maintaining desired RF shielding.
摘要翻译：与磁共振成像（MRI）装置一起使用的射频（RF）屏蔽可能会经历梯度场感应涡流和射频场感应涡流。这些涡流可以使RF屏蔽以不期望的速率加热。 RF屏蔽被设计为具有期望的RF屏蔽程度和期望的加热属性。 RF屏蔽的设计目标包括梯度场透明度和RF场不透明度，这两者都可以受涡流影响。示例性方法识别将引起涡流的梯度场，并识别将产生涡流的RF场。如果RF屏蔽上的区域被识别出将不能实现所需的加热属性，则可以在RF屏蔽中进行轴向切割和方位切割的图案，以减少RF屏蔽中的梯度涡流加热，同时保持所需的RF屏蔽。

摘要： The present invention provides an apparatus for reducing acoustic noise in a magnetic resonance imaging device including passive shielding located outside the actively shielded gradient winding elements in order to reduce the magnitude of fields that spread outside the gradient coil assembly in unwanted directions and interact with the magnet cryostat or other metallic magnet parts, inducing eddy currents that cause consequent acoustic noise. The passive shielding elements are conducting layers located on the outer radius of the cylindrical gradient coil assembly in a cylindrical magnet system, conducting layers located at the ends of the gradient coil assembly in a cylindrical magnet system, and conducting layers located inside the actively shielded gradient winding inner elements in a cylindrical magnet system. The passive shielding could also be located on separate structures that are vibrationally isolated from the magnet cryostat. The actively shielded gradient winding can also be extended to portions at the ends of the actively shielded gradient winding and further to portions inside the inner radius of the inner portion of the actively shielded gradient winding. The actively shielded gradient windings and passive shielding should be designed concurrently in order to substantially optimize the gradient linearity and reduce the eddy currents generated in metallic parts of the magnetic resonance imaging system.
