Abstract: A first plastic strip (21) has longitudinally spaced studs (22) each of which can be bent over at a 90 DEG  angle. A second strip (26) has holes (27) through which the studs fit and grooves (29) which receive and secure the bent over studs. Paper punched to receive the studs is clamped between the two strips. The studs are then bent over into grooves in the second strip and held in bent position. The grooves have overhanging lips (31) which detachably retain the studs in place. The paper is thus securely bound. To prevent cracking the studs, the abruptness of the 90 DEG  bend may be relieved by forming an annular depression (36) around the base of each stud.

Abstract: The invention refers to a method of purifying flue gases from refuse incineration by cooling and of recovering heat energy as well as to an arrangement for performing the method. According to the mentioned method the flue gases are cooled in three stages, with the most beneficial structural material with regard to the temperature range, process conditions, and economy being selected in each cooling stage among the materials glass, plastic or alloyed steel. The sizes of the various cooling surfaces are determined such, that the temperatures of the flue gases immediately before the last cooling stage lie closely above the water dew point. The arrangement disclosed by the invention comprises a first cooling member (2), a second cooling member (3) connected thereto, and a third cooling member (4) connected to the latter and having its outlet connected to a droplet separator (5) which is followed by a flue gas fan (6) which in turn is connected to a chimney (7). The first (2) and second (3) cooling members can preferably mainly consist of glass and plastic and the third cooling member (4) can mainly consist of alloyed steel.

Abstract: There is disclosed a digital enhancement circuit which responds to the complementary inductance provided by a planar coil sensor (L1, L2) which inductance varies in a complementary manner according to the position of a movable member associated with the planar coil configuration (L1, L2). The complementary inductance is coupled to an oscillator (30) whereby the period of the oscillator (30) is varied in a first mode according to a first inductance value and in a second mode according to a second inductance value. These signals are then processed by means of digital processing circuitry to develop a signal indicative of the difference of the periods as divided by the sum of the periods. This signal is a ratiometric signal, and by employing digital counters, one can provide an output signal having a predetermined gain factor and having the above noted ratiometric characteristic which signal is indicative of the position of the movable member as further enhanced by the gain factor.

Abstract: A circuit is described in which the bandwidth of the track circuit receiver (8) is design to be so narrow that it is virtually impossible for it to be subjected to interference. To permit interpretation of the frequency-modulated track voltage, the frequency deviation of which far exceeds the bandwidth of the receiver, the narrow band characteristic is achieved by means of an adjustable bandpass filter (7), the centre frequency of which is controlled so that it precisely follows the frequency of the track circuit transmitter (2). For this purpose, the output signal from the track circuit transmitter is fed to the track circuit receiver via a special lead (9). <IMAGE>

Abstract: A method of introducing supply air into a lower portion of a room space (3) directly to an occupied zone (7) by means of at least one elongated air distribution means (1) provided with a plurality of outflow openings (2) for supply air. In order to blow supply air into the occupied zone without draught and without drawing impurities from the upper portion of the room space, supply air is blown from the air distribution means at a high speed but through outflow openings so small that the speed of the air jets (A) from the openings is reduced essentially over a short distance (X) and the entrance of secondary air (B) from the room space into the air jets is prevented in the vertical direction of the room space over said distance (X) and at least at one end of the air distribution means. The air distribution means (1) is provided with a plurality of small outflow openings (2) the distance of which from each other in the longitudinal direction of the air distribution means is great as compared with the size of the outflow opening for enabling secondary air to flow from the room space in between the outflow openings, and to mix with the air jets from all sides.

Abstract: After the layers of printed circuit boards have been bonded together, the edges, which are thicker, are trimmed.  Each board (8) is supported by a table which is smaller than the board so that the edges overlap and is trimmed between two diamond toothed cutting wheels (10a,b) with their teeth meshing.  Each set of teeth makes a cut which does not extend to a depth equal to the thickness of the board. The height of a cutting wheel can be adjusted to match different board thicknesses.  The material (15) removed from the edge is displaced to a collection point by rollers rotated in synchronism with the travel of the board. During trimming, the board is held in contact with the supporting surface by centering rollers.  The process can be programmed for automatic control.

Abstract: A dehydrating screw press by which an advancing product to be deshydrated is pressed, by the rotating movement of one or more screw elements with a conical shaft (1) and a conical spiral (2) operating in a corresponding space up to the wall of a filtering cage (3). As the increasing diameter of the spiral (2) conforms to the like reduction of the shaft section (4), the use of the helical elements fitted side by side allows each spiral to operate with a profile extending up to the other helical element wall. Therefore, non-intermeshing zones are avoided during the dehydrating phase in the intermediate space. As the two pressing elements are rotated in opposite directions, rotation of the pressed material is avoided, thus advancing the product in an axial direction. The filtering cage used for a press with two helical elements shows a confirmity with two components (5 and 6) interconnected on lines (7 and 8) at the intermeshing area of the two spirals.

Abstract: The invention relates to a device for detecting a malfunction of a machine driven with a variable rotational speed by an electric motor, whereby the motor is switched off when a malfunction occurs. A regulating device which controls the motor records the operating values of the motor during a learning function and said operating values can then be used to detect malfunctions. The method steps used for this purpose provide a learning function of the regulating device before activating the malfunction detection. To this end, the machine and/or a unit actuated by the machine runs through all possible operating states in which the operating values of the motor recorded during the learning function are, in their association with the machine and/or the unit driven by the motor, stored, brought forward and used for monitoring malfunctions.
