A c o m p u t e r - c o n t r o l l e d r e p r o d u c t i o n device is described for recreating a 3-dimensional image representative of a subject image in a p e r m a n e n t m e d i u m such as a sheet o f t r a n s p a r e n t plastic. Digital signals representative of the subject image are stored in the m e m o r y o f the c o m p u t e r a n d used by the c o m p u t e r to control a machine tool for drilling a plurality of holes in the plastic sheet representative of the subject image. T h e m a c h i n e tool contains a drill bit which is tapered over the length o f its travel into the plastic sheet so the deeper the p e n e t r a t i o n into the sheet, the larger the diameter of the e n t r a n c e hole in the sheet. The depth of each hole is controlled by the c o m p u t e r to c o r r e s p o n d to the lightness of the subject image at that point.

2 In this screening bottom, the screening elements which are mounted on a support structure are provided with an exchangeable and automatically clamped rubber plate acting as a wear-and-tear resistant layer. Beneath the rubber plate, a reinforcing structure is provided consisting of plastic ribs a n d / o r a reinforced structure which is imbedded in a plastic material, as well as clamping elements. The reinforced structure and the clamping elements constitute a unitary grid which is undetachably coupled with the rubber plate. Thereby, it is possible to transfer the advantages from the unit construction assembly technique to screening bottoms with associated screening elements which basically are composed of rubber with a high abrasion resistance characteristic. No complicated and expensive vulcanization molds and devices are required for making the screening elements. The molding tools which are already available for making plastic screening elements can be partially used. 4383671 MOULDING TOOL Bengt Persson assigned to Br Perssons CementvarufabrikAB ,sI ~ ~5 w~"~~"~,L v, ~ ~.,~~[ ,, !

A moulding tool for making curb stones from vibrated concrete having a rather
high water content, the moulding tool being designed to offer good vibration properties and safe and simple removal of the curb stone from the moulding tool despite the fact that the concrete has a troublesome tendency of adhering to the moulding tool. According to the invention such a moulding tool is characterized in that the mould cavity is defined mainly by a main member of the moulding tool, said main member being a substantially rigid unit, and by two displacable end merebers, and that the moulded curb stone is removable from the main member in a direction parallel to the direction of displacement of the end members, the end members having means for exerting force on the curb stone when being displaced from the moulding position.

The present invention provides an inexpensive device particularly designed so as to permit easy, accurate adjustment of the working edge, edges, surface or surfaces of the movable head on any of a wide variety of mill and shop tools. A housing encloses a battery and number of spaced electrical contacts, so arranged that a circuit through a light-emitter and a soundemitter is made only when one of the electrical contacts engages a fixed-location site on the tool and another engages a working edge or surface. In this way the working edge(s) or surface(s) may be adjusted so as to just touch the contact which sets-off the light and sound. For versatility there is more than one of thesc working edge or surface-engaging contacts, variously located on the device for alternative use. A special housing shape is disclosed as is the use of permanent magnets for holding the device at a uniform location for certain uses.
