摘要： A unitary sign panel including a transparent, preferably phosphorescent, plastic sheet having opposed forward and rearward planar surface and grooves in the rearward planar surface of the sheet to form outlines of desired indicia viewable from the forward planar surface of the sheet. Additional grooves are provided in the rearward planar surface forming hatch patterns within the outlines of the selected indicia which are also viewable from the forward planar surface of the sheet. The additional grooves preferably have a depth less than a depth of the grooves. The unitary sign panel is free of materials at the forward and rearward surfaces of the sheet such that light is transferable through the sheet in a direction perpendicular to the forward and rearward planar surfaces of the sheet. The sheet has a thickness sufficient for viewing through the sheet in the direction perpendicular to the forward and rearward planar surfaces of the sheet so that a viewer can see objects on the other side of the sign panel. The grooves and the additional grooves are preferably each V-shaped in cross-section. The grooves are preferably formed by engraving so that the sheet is substantially translucent at the grooves and is opaque at an apex of the V-shaped grooves. The sign panel can utilize ambient light or can be provided with an artificial light source disposed at an edge of the sheet.

摘要： A frame structure for carrying a drum or other object in front of a person has a front support member engaging two substantially parallel side support members extending generally horizontally along the waist of a person, and is supported by the hips of a person. A back member, attached to the side support members, engages the back thoracic region of a wearer and provides a counteracting force to keep a drum or other carried article in a desired position. The back member includes a pair of telescoping lengthwise adjustable back support members terminating in a hinge point at a back plate. The back plate is provided with arcuate slots through which attaching bolts engage a flanged member of each of the back support members. This arrangement allows the angle between the two back support members to be adjusted in order to adjust the distance between the side members along the back of the person. The width of the frame may also be adjusted along the front of the person by adjustment of overlapping angle plates of the front support member. The side support members are slidably engaged with the front and back members to allow for adjustment in the front to back direction of the frame, thereby effectively changing the distance between the hip supported fulcrum and the front and back members. The frame is supported on the hips by means of a belt and pad assembly which removably attaches to the frame.

摘要翻译： 用于在人的前方携带滚筒或其他物体的框架结构具有前支撑构件，该前支撑构件接合沿着人的腰部大致水平延伸的两个基本平行的侧支撑构件，并且由人的臀部支撑。 附接到侧支撑构件的后部构件接合穿戴者的后胸部区域并且提供抵抗力以将鼓或其它被携带物品保持在期望位置。 后部构件包括终止于后板的铰链点的一对可伸缩的纵向可调节的后支撑构件。 后板设置有弓形狭槽，连接螺栓通过该弧形槽与每个后支撑构件的凸缘构件接合。 这种布置允许调整两个后支撑构件之间的角度，以便调节沿着人的后部的侧构件之间的距离。 框架的宽度也可以通过调整前支撑构件的重叠角板来沿着人的前部进行调整。 侧支撑构件与前部构件和后部构件可滑动地接合以允许在框架的前后方向上进行调节，从而有效地改变臀部支撑的支点与前部和后部构件之间的距离。 框架通过可移除地附接到框架的皮带和垫组件支撑在臀部上。

摘要： The invention provides a means by which a gas discharge lighting display can be made of virtually any material which can withstand temperatures over 110.degree. F. This display uses a bypass tube to isolate heat and contamination from the main channel of a gas discharge lighting display during its manufacture. The bypass tube is then removed to force the luminous discharge to pass through the main channel, providing a lighting or advertising display of high quality and reliability.
