Abstract: ABSTRACT OF THE DISCLOSURE    In a cover-frame assembly for a manhole or the like a locking device is provided, which comprises a closing member having at least two horizontal arms and a mounting rod provided with a bearing and actuating device.  The mounting rod and the bearing and actuating device are located in a bore having a widened bore portion, whereby a shoulder is formed, on which is supported a bearing surface of the bearing and actuating device. The ends of the arms each project into a guide link, which is shaped on the inner flange of the frame.  The guide link has an inclined flank, by means of which the arms are increasingly elastically deformed.  In the closed position of the locking device, the arms engage in locking recesses provided on the end of each inclined flank.  This leads to a self-closure with pre-tension.

Abstract: A BIPOLAR FIELD-EFFECT ELECTRICALLY ERASABLE    PROGRAMMABLE READ ONLY MEMORY CELL AND         METHOD OF MANUFACTURE             ABSTRACT OF THE DISCLOSURE           A floating gate electrically erasable MOS transistor comprising a silicon substrate having source and drain regions and a channel region disposed between the source region and the drain region.  The source and drain regions are formed from a semiconductor material having one conductivity type, and the channel region is formed from a semiconductor material having a conduc-tivity type opposite the conductivity type of the semi-conductor material forming the source and drain regions.          A control gate region is formed in the silicon substrate horizontally spaced apart from the channel region.  The gate region is formed from a semiconductor material having the same conductivity type as the semiconductor material forming the source and drain regions.  A poly-silicon layer bridges the control gate region and the channel region for communicating an electrical potential from the first gate region to the channel region.  A silicon dioxide layer is disposed between the polysilicon layer and the control gate and channel regions for in-sulating the polysilicon layer from these regions.  The polysilicon layer thus serves the function of a floating gate, and is selectively controlled through the first gate region for forming a conductive channel between the source and drain regions.  The drain region of the MOS transistor is coupled to the base terminal of a bipolar sensing transistor for forming an EEPROM.

Title: Bar code scanner

IPC: G06K7/10
Filed: 1989-08-31
Granted: 1994-05-03
Abstract: BAR CODE READER     ABSTRACT OF THE DISCLOSURE: In a bar code reader, a field of view which includes a symbol to be read is imaged upon a light-responsive array such as a CCD imager device. The output of this array is transferred to a memory array to provide a bit-mapped type of binary representation of the image including the symbol. The memory is scanned (instead of the field of view itself being mechanically scanned) to recognize and decode the symbol. Because the angular orientation of the symbol is variable, this binary representation may be interpreted to determine how the memory array is to be scanned to recognize the bar code symbol. For example, the distinctive patterns of characters used in bar codes may be found by scanning the memory and the relative positions of these patterns interpreted to determine the position, size and shape of the symbol in the memory, thereby defining at what angular displacement the memory array need be addressed to traverse the rows of the bar code symbol. Or, the memory array may be simply scanned using preselected scan lines (beginning with a raster-type scan) until code recognition is obtained.

Abstract: A structural assembly includes a square trough-shaped stone having inclined external corner regions and a dovetailed groove formed in each wall side. The dovetail tongue of a connecting plate fits into the dovetailed groove. At the lower end of the internal surface of each wall of the stone, a shoulder portion may be provided for accommodating base elements. The height of the connecting plate is advantageously greater than the height of the trough-shaped stone, so that the plate projects beyond the stone in a vertical direction for connection to further stones. With such an assembly, it is possible to erect dry-stone type walls of various types. The individual elements of the assembly can be produced rationally and economically, and it is also possible to produce end elements and corner elements from the trough-shaped stones by cleaving the stones along grooves provided for such purpose.
