Abstract: The display stand, for sales or advertising purposes, for example, has a front and a rear surface and two side surfaces and it can be collapsed into a transport position. After folding the side surfaces into the plane of the front and rear surfaces, the lower parts of the latter can be folded upwards, together with the adjacent lower parts of the side surfaces, until they rest on the upper surface parts. For unfolding, the display stand only needs to be lifted up so that the side parts drop down and, in doing so, the display stand automatically assumes its unfolded state. The unfolding can be assisted by elastic elements which are braced between the individual parts of the display stand in such a way that they pull these parts into the unfolded position (Figure 1). <IMAGE>

Abstract: The invention relates to biconvex lenses made from synthetic polymer which have the shape of a drop of a lighter liquid freely resisting on the surface of a heavier liquid immiscible with the lighter liquid, while the surface tension of the heavier liquid saturated with the lighter liquid in air is smaller than the sum of the surface tension of the lighter liquid saturated with the heavier liquid in air and the surface tension at the interface of both liquids being in mutual equilibrium. 
     The lenses are produced in such a way, that a drop of a polymerizable lighter liquid comprising one or more mono- and/or multifunctional monomers and a polymerization catalyst, and eventually an inert diluent, is applied on the surface of a heavier liquid, and then the monomers of the polymerizable lighter liquid are polymerized.

Abstract: A DC motor (12) is supplied, from a motor driver (13), with a brake voltage constituted by a forward drive voltage, a reverse drive voltage, and a stop voltage of a zero potential level. An operational current of the motor driver (13) is supplied to a low-­pass filter (14) whose output is supplied to first and second sample and hold (S/H) circuits (15, 16). The first S/H circuit (15) performs its sampling operation after a minute period of time in which the brake voltage goes through a polarity inversion from the reverse drive voltage to the forward drive voltage. The second S/H circuit (16) performs its sampling operation after a minute period of time in which the voltage applied is changed from the forward drive voltage to the reverse drive voltage. The outputs or sampled values of both S/H circuits (15, 16) are compared with each other by a comparator (17). When the sampled values equal each other, i.e., when the number of rotations of the motor (12) becomes zero, the comparator (17) outputs a coin­cidence pulse. This pulse is supplied to a stop detec­tor (18). When detecting this coincidence pulse a predetermined number of times in a row, the stop detec­tor (18) discriminates that the number of rotations of the motor (12) has become zero.

Abstract: A non-volatile electro-optical read-only memory includes a substrate on which is printed (or otherwise inscribed) a complex symbol or "label" with a high density two-dimensional symbology, a variable number of component symbols or "codewords" per row, and a variable number of rows. Codewords in alternating rows are selected from mutually exclusive subsets of a mark pattern such as a (17,4) mark pattern. The subsets are defined in terms of particular values or a discriminator function, which is illustrated as being a function of the widths of bars and spaces in a given codeword. In the illustrated embodiment, each subset includes 929 available codewords; that, plus a two-step method of decoding scanned data, permitting significant flexibility in defining mappings of human-readable symbol sets into codewords. The memory may be used in conjuction with a scanner and a suitable control system in a number of applications, e.g., robotic operations or automated microfilm searching.

Abstract: The disclosed arrangement maintains the latest file attributes such as file size, modify time, and access time, at the server data processing system in a distributed data processing system. The server data processing system combines information requested from the client data processing system that has permission to write to the file with information periodically received from other client data processing systems that may be extending the same file by mapping the file into their own virtual address space. In this way, the server can maintain the latest file size attribute even when some clients are extending the file through system calls and other clients are extending the file through mapped access. To maintain a latest modify time and access time, the server keeps a modify count and access count. The client data processing systems periodically send to the server data processing the modify count and access count that have been incremented whenever the client data processing system modifies and accesses the file. The server data processing system compares the counts at the server with the counts received from the clients to determine a latest corresponding modify time and access time.
