Patent DE-3584901-D1 (DE)

Abstract: A digital filter uses a digital wave filter (N) as a coupler to divider up the frequency band of the input signal (a1). The signals at the two outputs of the coupler are reduced in sampling rate (c1,c2) and one (c1) of them is inverted (-1). A transposed digital wave filter (NT) is used to combine the two output signals and produce at one output the reconstructed signal (b1,b2) in inverted or noninverted form. The output from the coupler may have its sampling rate further reduced and passes via further digital wave filters acting as couplers to divide up the frequency further. Further transposed digital wave filters are used to produce an output.

Abstract: The units connected in a daisy chain line are channel adaptors of a communications controller. The adaptors are connected through a bus (14) to a central control unit. All the units are connected with the bypass line (26-IN, 26-OUT). The central control unit cooperates with programs in the control store and adaptor logic circuits (20). Having identified the units, if any, which have to be disconnected from the daisy chain, a bypass-out control signal is sent to the unit which precedes each such identified unit and a bypass-in control signal to the unit which follows each such identified unit. In response to the bypass-out control signal (48), a respective first, second AND gate (52,70) is not-conditioned, conditioned. The signal output from trap and control logic (45) is passed through a driver (72) to the bypass-out line (26-OUT).

Title: Apparatus and method for detecting a tool edge

IPC: G01D1/18
Filed: 1987-03-20
Granted: 1989-08-31
Abstract: A force transducer and circuit are used to detect the edge of a rotating grinding wheel. The force transducer produces an output signal indicative of a force applied thereto. The output signal is filtered by a high pass filter coupled to the output of the transducer. The amplitude of the filtered transducer output signal is compared to a reference value. An output pulse is produced if the amplitude reaches a predetermined level with respect to the reference value. A time responsive to a first output pulse establishes a fixed interval during which the number of subsequent output pulses is counted. If the number of pulses counted during the fixed interval reaches a predetermined quantity, a control signal indicative of edge contact of the grinding tool with the force transducer is produced.

Abstract: The application disclosed a method and machine for the automatic setting of bricks onto a supporting layer. So far, prefabricated wall panels have been made by setting the bricks manually into a mold equipped with brick compartments and intended for the said panel. A separate mold had to be prepared for each different panel shape. The object of the present invention is to facilitate, speed up and decrease the cost of the setting of bricks. In the machine according to the invention, the method is carried out by feeding into a cassette conveyor (1, 2, 3, 4) a batch of filled cassettes, of which the first is directed to below the brick take-off device (5). When the cassette conveyor is full and the first cassette is under the take-off, the automatic operation of the machine is started. The brick take-off lifts the topmost brick layer from the cassette and lowers it onto a brick conveyor (6), wherefrom the brick rows are directed onto a transverse belt conveyor (8). A rotating wheel (9) has been fitted to receive one brick at a time into a compartment at its periphery and, after rotating half a round, to lower it onto a flight conveyor (10). The flight of the flight conveyor takes the brick fed by the turning device, or remains vacant if the rotating wheel has been programmed not to rotate and not to deliver a brick onto the flight. A full row of bricks is formed on the flight conveyor, and a pushing device (11) pushes the row onto a centering table (12), on which the distances between the bricks are evened out. A pick-up device above lifts the centered bricks, centering them in their longitudinal direction, and lowers them into the mold in one, two or several batches, in accordance with the desired bond, the machine moving forward one step between the lowerings in accordance with the programmed bond. The machine stops at the latest upon the panel being completed and also upon the cassettes having been emptied.

Abstract: In the stepwise feeding of a packing material web for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located as long before the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this it is proposed in accordance with the invention to sense the passage of the actual pouring opening and start a countdown sequence, at the end of which the web feed is interrupted with the pouring opening in correct position for the application of the cover strip. An arrangement for the realization of this, seen in the direction of feed of the material web (1),comprises a sensing device (4), a processing device (5) and a forward feeding device (9) which are connected to a control unit (13)

Abstract: A method of forming an electrical heating element in the form of an electrically non-conductive supporting body onto which an electrically resistive material is deposited, the method comprising the steps of preparing a dry metal powder of irregularly shaped metal particles of widely varying sizes, in the range 20-150 microns, roughening the surface of a supporting body onto which a heating element is to be formed, pre-heating said surface of the supporting body to a temperature within the range of 150-250 DEG C and flame spraying the dry metal powder onto said heated surface of the supporting body in a plurality of passes over the supporting body. The effective resistivity of the flame sprayed deposit is predetermined by adjusting the amount of oxidation on the surfaces of the metallic particles sprayed onto the supporting body. The amount of oxidation on the surfaces of the flame sprayed particles, and hence the resistivity of the sprayed deposit, can be varied by selecting the size range of the particles used, within said range of 20-150 microns. Alternatively the amount of oxidation on the surfaces of the flame sprayed particles can be varied by blending selected alloys into the powder to by sprayed such as to adjust the quantity of conductive oxides present on the sprayed particles.
