Abstract: In a method of marking faults on rapidly moving material webs the material web is moved past a fault detection scanning device, which cyclically scans the web transverse to its longitudinal direction, and past a marking device at a defined distance therefrom. Signals coming from the fault detection scanning device (16) are analyzed one after the other to determine whether they are fault signals or structure signals. The fault signals which are detected are stored with their web coordinates. Checks are made at short time intervals as to whether a fault signal is present in the store (11) which corresponds to the longitudinal coordinate which is just moving past the marking device (13). A marking is effected if a fault signal is present at the corresponding web coordinates (FIG. 1).

Abstract: A roof structure for an automotive vehicle with a reinforcement for a roof panel is especially applicable for the vehicle having a sun-roof. Longitudinal reinforcement for the roof panel is provided by one or more pressed reinforcement ribs formed in the roof panel and extending parallel to the longitudinal axis of the vehicle. Each reinforcement rib has a front end located near the rear lateral edge of the sun-roof. A stiffener extends perpendicular to the axis of the reinforcement ribs and lies across the front ends of the reinforcement ribs for reinforcing the front ends at which bending stresses tend to concentrate.

Abstract: A sorting machine comprising several devices for introducing objects into the machine and a mechanism for conveying the objects to magazines mounted on the outer side of a cylindrical casing of the machine. The conveying mechanism is made in the form of a rotary drum of the squirrel cage type and a fixed cylindrical cam having cam surfaces which are coaxially mounted in the casing and are coaxially relative to each other. Rods are provided with object carriers which are movable along the rods, each object carrier being operatively connected to a respective cam surface of the cam for distributing the objects among the magazines. At the points of conjunctions of the cam surfaces there are provided switches which are actuated by a control device of the machine. During rotation of the driven drum, the object carriers which are guided by the cam surfaces of the cam are moved along the rods to distribute the objects among the magazines.

Abstract: The method detects a toner concentration in a developer comprising a mixture of magnetic carrier particles and a non-magnetic toner through the determination of a leakage magnetic flux with a Hall element having a high sensitivity. The mixture is first shaped into a predetermined configuration and brought into a fixed magnetic field where the leakage magnetic flux is sensed by the Hall element. The shaped mixture may be a magnetic brush per se in case of the well-known magnetic brush device used. Such a Hall element is very susceptible to a variation of environmental temperature and thus requires a compensation therefor upon the determination of magnetic field. In one aspect of the invention, the compensation may be conveniently achieved by detecting a voltage across the control current terminals of the Hall element and supplying the detected result into an input of analog calculator.

Abstract: A beverage dispenser having a flow-actuated sensing member positioned within a dispensing line thereof and which is operative to sense and record the dispensing of preselected volumes of a beverage. Fundamentally, the invention includes a switch positioned within the flow line and actuated by the flow of the beverage to enable timing circuits which determine the volume of beverage dispensed based upon the time of dispensing. Actual control of the timing and recording circuitry is achieved by sensing of the beverage flow rather than by operator-actuated elements.

Abstract: A machine-retrievable card and associated card retrieval apparatus and method therefor is disclosed in which the card is provided with a code-notched sorting edge located between the leading and trailing card edges which has (a) a predetermined configuration of complementary and primary digit code teeth which are removed and retained, respectively, to encode the card with a particular digit, and (b) an acquisition tooth at the leading edge and associated acquisition slot, and (c) a return tooth at the trailing edge and an associated notch. The card retrieval apparatus includes complementary and primary code blades which selectively engage associated complementary and primary code slots of the card, respectively, as well as a pair of acquisition blades and a pair of return blades which cooperate with the acquisition and return teeth, respectively.
