Abstract: An apparatus for measuring the speed of a projectile fired from a handgun or small arm has a measuring path, over which the projectile passes, with light gates disposed spaced apart from one another. Each light gate has a light responsive element, which is shielded from the projectile path by a screen containing a light admitting aperture. An electronic signal evaluation circuit processes the signals emitted by the two light responsive elements in accordance with the darkening of the apertures caused by the projectile in flight above them and supplies these signals to a display device. In order to reduce to a minimum the danger of damage to the apparatus or of harm to persons, caused either by the projectile itself or by parts broken off the apparatus by the projectile without providing a connection between the barrel of the gun and the measuring apparatus, the arrangement is selected such that the two light responsive elements are disposed behind a separating wall common to both. The separating wall includes the light admitting apertures and acts as a screen. It is aligned substantially parallel to the projectile path and extends from near the muzzle of the weapon to beyond the second light responsive element, that is, the one disposed most remotely from the muzzle, and this separating wall protects the light responsive elements from the projectile.

Granted: 1987-09-09
Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.

Abstract: Crimping press (26) comprises an anvil (10) and a die (12) which is movable towards and away from the anvil. The anvil is moved by a rotating shaft (18) having a crank-type coupling (14, 16) to the die (12). The shaft (18) is capable of limited movement in the direction of movement of the die towards the anvil. The shaft issupported against such movement by a yieldable shaft support (46) that is calibrated to resiliently yield upon development of a predetermined reaction force in the die (12) during the final stages of crimping. When a terminal (6) is crimped onto a relatively small diameter wire (8), the shaft (18) will not be moved at all or will be moved by only a slight amount if the predetermined force is reached. When a terminal (6a) is crimped onto a larger diameter wire (8a), the predetermined reaction force will be developed before the die (12) reaches the limit of its travel towards the anvil (10) and the shaft (18) will move away from the anvil to accommodate the remaining movement of the crank pin.

Abstract: A circuit for protecting electronic devices which are fed from a source of dc voltage and to which a subscriber's line (ASL) is connected. In order to limit the current in the event of an overload on the subscriber's line (ASL), a MOSFET (T1) is provided as current-limiting component. The MOSFET (T1) is disconnected and re-connected periodically by means of a relaxation generator (K) when the MOSFET is in its current-limiting condition. Upon the normal operation of the circuit, the relaxation generator (K) does not operate. By proper dimensioning thereof, the time for which the MOSFET (T1) is blocked can be roughly adjusted as compared with the time in which it acts as current limiter. In this way, too great a heating of the MOSFET (T1) is avoided.
