摘要： A method and apparatus for uniformly polishing the magnetic recording layer of a floppy disc by producing uniform relative velocities between the magnetic oxide material and the polishing medium across the floppy disc. The floppy disc is placed on a circular resilient pad disposed on a first spindle-mounted circular platen. A circular fibrous or abrasive polishing disc is disposed on a second spindle-mounted circular platen. The radius of the polishing disc is greater than the width of an annular region to be polished on the floppy disc, so that the relative velocities between points of the polishing disc and adjacent points of the floppy disc are uniform. Uniform polishing of the annular region results when the rotating polishing disc contacts the annular region of the rotating disc when the first and second platens are rotated in the same angular direction, at first and second predetermined angular velocities, respectively.
摘要翻译：一种用于通过在软盘之间产生磁性氧化物材料和抛光介质之间的均匀的相对速度来均匀地抛光软盘的磁记录层的方法和装置。软盘放置在设置在第一主轴安装的圆形台板上的圆形弹性垫上。圆形纤维或研磨抛光盘设置在第二主轴安装的圆形台板上。抛光盘的半径大于在软盘上要抛光的环形区域的宽度，使得抛光盘的点与软盘的相邻点之间的相对速度是均匀的。当第一和第二压板在第一和第二预定角速度下以相同的角度方向旋转时，当旋转的抛光盘接触旋转盘的环形区域时，会导致环形区域的均匀抛光。

摘要： A center fold is produced in a floppy disc envelope by partially folding a pre-cut sheet of polyvinyl chloride (PVC) having two spaced center holes. The center holes are forced over a precision pedestal affixed to a flat support surface. A first fold bar is lowered against the partially folded sheet, flattening first and second sections of the sheet on each side of a fold line against the support surface, producing a fold of controlled radius. A heat lamp is utilized to anneal the fold for a predetermined time, after which the fold bar is raised. A flap extending from the first section of the sheet is folded back against the second section of the sheet by means of an apparatus including a flat support, a precision pedestal for aligning and retaining the partially folded envelope, and a second fold bar having a lip for engaging the edge of the flap. The second fold bar moves along an arcuate path controlled by a four bar linkage, folding the flap back against the second section and simultaneously forcing the fold end of the flap against a resilient pad adjacent a rigid stop attached to the support surface, producing a permanent end fold having a controlled radius of curvature. The folded flap is then sealed by means of an apparatus including a clamp bar, a heat lamp, and a movable hot sealing bar. After the envelope is aligned, the clamp bar engages the flap adjacent the end fold and forces the flap against the envelope. The heat lamp is turned on, annealing the fold. The hot sealing bar is forced against the free end of the flap, welding the end of the flap to the envelope.
摘要翻译：通过部分地折叠具有两个间隔开的中心孔的聚氯乙烯（PVC）的预切片材，在软盘封套中产生中心褶皱。中心孔被压在固定在平坦支撑表面上的精密基座上。第一折叠杆相对于部分折叠的片材降低，将折叠线的每一侧上的片材的第一和第二部分压平在支撑表面上，产生受控半径的折叠。使用加热灯将折叠退火预定时间，之后折叠条被升高。从片材的第一部分延伸的翼片通过包括平坦支撑件的装置折叠抵靠片材的第二部分，用于对准和保持部分折叠的外壳的精密基座，以及具有唇部的第二折叠杆用于接合翼片的边缘。第二折叠杆沿着由四杆连杆控制的弧形路径移动，将挡板折叠抵靠第二部分，同时迫使折翼的折叠端抵靠附接到支撑表面的刚性挡块上的弹性垫，产生永久端部折叠具有可控的曲率半径。然后通过包括夹杆，加热灯和可移动热密封条的装置密封折叠的折翼。在信封对齐之后，夹紧杆与靠近端部折叠处的翼片接合，并迫使翼片抵靠信封。加热灯打开，退火折叠。热密封条被迫靠在挡板的自由端上，将挡板的端部焊接到信封上。

摘要： A fishing rod of hollow tubular construction with a side inlet opening for the fishing line adjacent the handle end and a line exit opening adjacent the tip of the rod. Within the tubular rod are located spaced line guides at intervals which are progressively shorter towards the tip of the rod, the line guides being formed of an anti-friction material and so positioned and constructed that when the fishing rod is bent through about 90.degree. the fishing line will not contact the interior surface of the rod.

摘要： A motorcycle trailer comprising two body parts hingedly connected with each part having triangular sides and a rear wall on the upper part. A wheel suspension is secured to the lower part and comprises a pair of leaf springs having a transverse tubular member secured to their lower ends and a pair of shock absorbers between the tubular member and the lower body part. A pair of wheels are mounted on spindles at the ends of the tubular member. A pair of link assemblies hold the upper body part in an open position at an acute angle. A bed comprising two parts hingedly connected is positioned in the lower body part. With the bed in open position the part extending from the lower body part is supported by a pair of U shaped frames pivoted to the underside of that part. A canopy is supported by the partially open upper body part and a collapsible frame. A universal hitch is provided for attaching the trailer to the luggage rack of a motorcycle.
