    • A reciprocating drafting pen device is provided for automatically lifting a technical pen and replacing it onto drafting paper while the pen is drawn transversely across the paper, for stippling, or for the drawing of various other interrupted lines. The apparatus includes a barrel, a piston mechanism disposed within the barrel and longitudinally movable therein, a technical pen held by the piston mechanism and movable therewith, including an ink reservoir and a pen nib extending out one end of the barrel. A guide foot is adjustably attached to one end of the barrel for maintaining a desired standoff between the barrel and the drafting paper to be inked. An electromechanical drive mechanism moves the piston mechanism longitudinally, and thereby also moves the drafting pen such that the nib is brought alternately into contact and out of contact with the drafting paper. Favorably, one or more adjustable piston stops can be provided for to facilitate removal of the technical pen from the piston mechanism. The drive mechanism can include a solenoid, a piezoelectric drive mechanism, or a motor-driven cam.
    • 提供一种往复式牵伸笔装置,用于自动提升技术笔并将其更换到牵伸纸上,同时笔横向穿过纸张,用于点画或绘制各种其他中断线。 该装置包括一个筒体,一个活塞机构,设置在筒体内并可在其内纵向移动,一个由活塞机构保持的可移动的技术笔,包括一个墨水容器和一个延伸出筒体一端的笔尖。 引导脚可调节地附接到筒的一端,用于保持筒和待着墨的牵伸纸之间的期望的间隔。 机电驱动机构使活塞机构纵向移动,从而也使牵伸笔移动,使得笔尖交替地与牵伸纸接触并脱离接触。 有利地,可以设置一个或多个可调节的活塞止挡件,以便于从活塞机构移除技术笔。 驱动机构可以包括螺线管,压电驱动机构或马达驱动的凸轮。

    • A collar edge construction for a knitted garment. The construction includes a garment body provided with a finished lower edge and sleeves suitably attached opposite side of the upper end of the garment body. The body is cut away in the usual manner at its upper extremity to form a neck opening. The neck opening is visibly framed by a strip of collarette material which is folded longitudinally to form inner and outer layers. The lower portion of the outer layer is preferably folded inwardly to form a folded portion. The lower edge of the inner layer is also preferably folded to form a second folded portion. In accordance with the preferred embodiment, the edge of the body extends upwardly between the layers substantially to the longitudinal fold in the collarette. Preferably, at least two parallel lines of stitching pass through the lower portions of the collarette strip and the body fabric to complete the assembly. Because both edges of the collarette are folded inwardly, no raw edges show. The resulting construction is durable, has a natural tendency to lay flat, and provides an attractive finish in the neck of the garment.
    • 针织服装的领口边缘构造。 该结构包括一个设有完成的下边缘的衣物和适当地安装在衣服主体上端相对侧的套筒。 身体以其通常的方式在其上肢切除以形成颈部开口。 颈部开口由一条可折叠的条纹材料构成,纵向折叠以形成内层和外层。 外层的下部优选向内折叠以形成折叠部分。 内层的下边缘也优选地被折叠以形成第二折叠部分。 根据优选实施例,本体的边缘在层之间向上延伸,基本上延伸到肩胛骨中的纵向折叠。 优选地,至少两条平行的缝合线穿过导光条和身体织物的下部以完成组装。 因为领coll的两个边缘向内折叠,所以没有原始边缘显示。 由此产生的结构是耐用的,具有平放的自然倾向,并且在服装的颈部提供有吸引力的完成。
