摘要： The invention is a magnetically actuated clapper-style armature wire matrix print head. A light weight highly reliable and low cost design is achieved by utilizing single molded parts wherever possible. A unitary molded straight line channel wire matrix wire guide is molded as a single part. The flux return member is a single formed part with attached magnetic cores. The magnetic cores have thermal contact with an attached or integral heat sink that extend from the flux return member in the axial direction with the cores and which may be integrated with the support frame for the print head structure. A rebound absorbing backstop member receives the armatures on the rebound but also serves as a means of maintaining pivotal contact between the end of the armatures and the top edge of the flux return member so that a continuous flux path from the flux return member, through the armature and down through the cores of the electromagnets can be attained.
摘要翻译： 本发明是一种磁力驱动的敲击式电枢线矩阵打印头。 通过在可能的情况下使用单个模制零件来实现重量轻，可靠性和低成本设计。 单一模制的直线通道导线矩阵导线器被模制成单一部件。 磁通返回构件是具有附接的磁芯的单个成形部分。 磁芯与附接或整体散热器热接触，该散热器从磁通返回构件在轴向方向上与磁芯延伸，并且可与用于打印头结构的支撑框架一体化。 回弹吸收支撑构件在回弹中接收电枢，但也用作在电枢的端部与磁通返回构件的顶部边缘之间保持枢转接触的装置，使得来自磁通返回构件的连续磁通路径通过 可以实现电枢和电磁铁芯的下降。

摘要： A device for determining the direction of a fluid spray pattern issuing from a fluid nozzle prior to flowing through the nozzle includes a body in the form of a template or a jig releasably attachable in a predetermined orientation to the nozzle tip. The body includes a pair of angularly related adjustable arms having axes which intersect the nozzle aperture and which extend such that the central axis of the nozzle bisects the angle between the arms. By applying the device to the nozzle tip in predetermined orientation, the arms define the lateral extremities of the spray pattern.
