Title: Photoelectric Method and Apparatus for Detecting the Position of Edge-defined Structures
IPC: G01B11/00
Filed: 1982-01-07
Abstract: The invention can be used in optical precision measuring instruments, such as coordinate measuring machines, or in processing machines, such as in apparata for photolithography, and also for the scanning of edge-defined and line- defined structures. With the aim of ensuring rapid, objective and contactless detection of measured quantities in the measurement of optically effective structures which are not necessarily stationary with respect to a fixed reference system and which do not have to have any particular orientation relative to the reference system, the invention provides a method and a receiver arrangement for two-dimensional orientation- independent detection of the position of the structure. The radiant flux determining the position of the structure is evaluated by an array of photodetectors 1', 11'-14' the outputs of which are combined to produce a signal having a predetermined value eg. zero, when the structure is in a predetermined position relative to a reference point O regardless of the orientation of the structure. Concentric circular and annular detectors may be used. <IMAGE>

Patent GB-2114048-A (GB)
Title: Method and apparatus for feeding plastic sheet material
Inventor: MOHS THOMAS J
IPC: B31F1/26
Filed: 1982-12-08
Abstract: A method and apparatus are disclosed for holding and feeding a continuous sheet (12) of plastic in an operation such as thermoforming. Articulations (13), such as alternating waveforms, are formed on the edges of the plastic sheet (12) by heating and pressing the edge, producing inwardly facing abutment surfaces at the edges of the sheet. The sheet is then passed into slots (34) in guide rails (32) with the inside surfaces (35) of the guide rails (32) engaging the abutment surfaces on the plastic sheet (12) to prevent the sheet from slipping out of the guide rails. The plastic sheet is thereby held firmly so that it can be passed through such thermoforming operations as heating in an oven (14), forming with a mold at a forming station (40), and cutting the formed articles away from the remainder of the sheet by a trim press (53). The sheet is advanced in increments through the thermoforming apparatus by a sheet advance mechanism (48) which alternately grasps the sheet to advance it and then releases the sheet while the forming and trimming operations are carried out. Holding and guiding of the plastic sheet in this manner allows maximum use of the area of the plastic sheet for forming articles and minimizes the waste plastic left after trimming. <IMAGE>
