Abstract: A stock certificate (10) carries a deposited layer (16) of magnetic material having a nonuniform magnetic characteristic, and a magnetic recording (14) of data derived from magnetic sensing of the layer (16). Authenticity and identity of the certificate (10) are checked by comparing (82) the result of a fresh sample-­digitized sensing (70,80) made longitudinally of the layer (16), with digital data read (62,72) from the recording (14), after the layer (16) has first been submitted to erasure (66,76) and then to a DC or AC, linear or non-linear, recording (68,78). The nonuniform magnetic (remanent) characteristic of the layer (16), is unique to the document (10), being dependent on nonuniformities of the layer (16) in regard to longitudinal-section (Fig 2), material and magnetic-particle distribution. These nonuniformities arise randomly during print-deposition of the layer (16) and from irregularity of the paper (or paper-like) surface (20) on which it is deposited; nonuniformity is enhanced by lacquer coating (17) of the layer (16). Compensation for wear of the document (10) can be made (Fig 6) by sensing the layer (16) to different depths (88,92 Fig 6; 102,104 Fig 7) differentially.

Abstract: Video effects apparatus comprises a pattern generator (102) for generating a mix control signal which, when used to control the combination of first and second input video signals to provide an output video signal, defines the geometrical shape in a composite output scene of a transition between a first component scene represented by the first input video signal and a second component scene represented by the second video signal. The pat­tern generator (102) responds to a size control signal (104) by causing the mix control signal to vary in a manner such that the area of the composite output video scene that is occupied by the first component scene changes relative to the area of the second compo­nent scene while the geometrical shape of the tran­sition between the component scenes remains the same. A shadow generator (12) generates a signal which adjusts the visual characteristics of the second component scene synchronously with the variation of the control signal.

Abstract: Through subjecting a probe (6), from its original position at a distance from the shell, of an egg (1) to a continuous force directed at the egg's shell, forcing the probe is forced down to strike against the shell, and this results in an elastic deformation of same, whereupon the resilience of the egg shell causes it to return to its original shape, throwing back the probe, whereafter the probe (6), again as a result of the continuous force, is brought to strike against the shell once more before again being thrown back. This action is repeated several times, with decreasing oscillations, so that the probe's action seen as a whole is a bouncing movement against the said egg shell. This movement is in principle observed as a decreasing oscillation, in connection with which the amplitude and duration of each of the probe's oscillations is measured, preferably electrically, and the number of oscillations from which the amplitude and duration exceed preset parameter values is counted and registered electronically, whereupon the above cycle is repeated a given number of times (n), and distributed evenly around the said egg's axis of symmetry. The lowest registered number of oscillations from the (n) examination cycles is registered against an empirical parameter.

Abstract: A continuously variable ratio beam splitter and beam launcher (10) for dividing an input light beam (13), particularly a polarized coherent light beam, into two output beams, within a broad intensity variation range between the beams which may approach zero to 100%, without loss of polarization, comprises an optical array on a support adjustably mounted on a frame (15); the optical array includes an optical divider aligned with a penta prism that effectively couples the optical divider to one side surface of a right angle output prism. The optical divider and the output prism launch two output beams, based on division of the light from the input beam impinging on the optical divider. Variation of the intensity ratio of the output beams is accomplished by rotating the optical array support about a pivot point aligned with the input beam so that the input beam strikes the optical divider at different angles. Each output beam is picked up by an optical fiber or like transmission element previously located at a fixed position on the frame of the device. The output beams are always aligned along essentially the same output paths, regardless of changes in the angular orientation of the optical array, so that the amplitude ratio between the two output beams can be changed merely by rotational adjustment of the optical array without refocusing or adjusting other components of the device.

Abstract: The internal gear pump has a pinion (3) and an internal gear wheel (1). On the pressure side the teeth engage with a contact ratio equal to or greater than 2 in such a way that a number of reciprocally isolated tooth cells are produced. At least a plurality of these tooth cells are each connected by a non-return valve to the common pressure duct. The power requirement of an internal gear pump of this type is reduced by virtue of the fact that the tooth gaps of the internal gear wheel (1) outside the rolling circle have a much wider cross section than the generating curve of a pinion tooth and/or that the outlet apertures are only slightly smaller than the tooth cross section of the internal gear wheel. The contact ratio of the sealing flanks may be equal to or greater than 3 and the contact ratio of the drive flanks between 1 and 2. <IMAGE>

Abstract: A non-volatile semiconductor memory device includes a voltage supply circuit (14) for supplying a positive voltage (Vcs) to the source line (SL1, SL2, ...) or bit line (BL1 to BLn) to which a low biasing voltage is applied with respect to each of non-volatile memory cells (MC11 to MCmn) in a memory cell array (MCA) in a data read mode. Since this voltage supply circuit (14) applies the positive voltage to the memory cells (MC11 to MCmn) in the data read mode, an effect equivalent to a back gate biasing effect to the memory cells (MC11 to MCmn) can be achieved. When the memory cell (MC) in an overerase state is present, the threshold voltage of this memory cell (MC) is substantially shifted to a pos­itive value in the data read mode.
