Abstract: The support element (1, 18) for several terminal strips (2), to be attached thereto, of a main distribution frame of a telecommunication system, particularly a communication system, is constructed as a plastic part by means of whose shape a recess (3, 19) used as wire duct is formed. The attachment to a mechanically rigid mounting plate (6) is affected without screws by hooks existing at the underside which engage corresponding cut-outs. The permanent connection between support element and mounting plate is effected via a connecting element, injection moulded with a rupture joint, in the form of the latch bolt (10, 23). Recessed mouldings (16, 30 and 26, 28) are provided for receiving a wiring hook (17, 27) used as support element for the wires.

Abstract: In order to measure the radiative power of a laser beam (L), the scattered light (SL) produced by the laser is preferably detected via at least one photodiode (H4), especially in the laser resonator itself, and fed to an evaluation circuit (AWE). In this regard, it is particularly advantageous in the case of a laser that is used for inscribing parts to evaluate the scattered light occurring in the interior of a component (K) for rapidly shading or uncovering the laser beam (L) for the duration of an inscription process. A special evaluation circuit facilitates the reliable detection and display of a measured value formed in this way even in the case of very brief inscription processes. <IMAGE>

Abstract: A basic fuel injection pulse width value (Tp) indicating an individual performance of an injector and an intake air flow amount value (Qa) indicating an individual performance of an air flow sensor are prepared. A deviation of a mean value (α mean ) from a target value (1,0) of an air-fuel ratio correction coefficient is calculated as a deviation value and is divided at a predetermined rate into divided deviation values (δ₁, δ₂) in correspondence with the basic fuel injection pulse width and the air intake amount value (Qa). The divided deviation values are memorized in the memory areas as learning values for controlling an air-fuel ratio, respectively. A corrected fuel injection pulse width is requested under the memorized learning values.
Patent EP-0371220-A2 (EP)
Inventor: GRONE SIEGFRIED
IPC: B21H1/06
Filed: 1989-09-19
Abstract: The invention relates to a radial die-rolling machine in which the roll groove is formed by a radially acting die ring on the outside, a radially acting, fixed and non-displaceable arbor roll entering the workpiece from below, an axially acting arbor-roll plate which closes off the roll groove from below and an axially acting bevel roll which defines the roll groove from above and swings away radially and axially. The rolling plane is inclined. The loading and unloading is considerably facilitated. Since rolling plane, rolling slide guide, groove mounting and feed cylinder lie in one plane, optimum radial die rigidity results. Since the workpiece ejector and the arbor-roll mounting are arranged on one side, namely below the workpiece, the arbor roll can be constructed to be fixed and therefore need not be moved for loading and unloading. This likewise increases the rigidity in the roll groove and necessitates only one infeed axis. The distance between the fixed arbor roll and the receiving point for the workpiece blank is always the same. This permits unloading of the rolling machine by a simple swivelling mechanism. In addition, high annular parts (bushes) can be produced.

Title: Active noise control
Inventor: EDWARDS JOHN WILLIAM
IPC: G10K11/178
Filed: 1989-04-24
Abstract: An active noise control system for controlling noise propagated through a duct (1) comprises a first microphone (5) located to receive the propagated noise at a point in a plane perpendicular to the length of the duct. A loudspeaker (6) is located substantially at that plane for introducing sound into the duct. An analog first control circuit (8,9,10,11) is operative in response to the noise received by the first microphone to feed a signal to the loudspeaker such that the sound introduced thereby destructively interferes with the noise at that point. A second microphone (13) is located further downstream to receive residual noise propagated along the duct despite the destructive interference. A second control circuit (14, 15,16,17), responsive to the residual noise received by the second microphone, controls parameters of the analog first control circuit so as to minimise the residual noise. In particular,the first control circuit includes an integrator (9) which has a transfer function which is electrically controlled by the second control circuit.

Abstract: To simplify the preprogramming of receivers, particularly of video recorders, taking into consideration timeshifts in the programme contribution concerned, it is known to generate additional information items such as programme source information, day of the week, start time and end time at the transmitting end, which are transmitted together with the television signal. These additional information items are also contained in the programme tables of a teletext signal and can be input into a memory of the receiver on command. When the transmission is shifted, for example by one "VPS day" or more, a further additional information item is generated at the transmitting end, by means of which updating, in particular correction, of additional information items already stored in the receiver is made possible. The novel method can also be used for controlling receivers which only contain a VPS decoder for decoding the additional information items. <IMAGE>

Abstract: In a bar code reader, a field of view which includes a symbol to be read is imaged upon a light-responsive array such as a CCD imager device (12). The output of this array is transferred to a memory (20) array to provide a bit-mapped type of binary representation of the image including the symbol. The memory is scanned (instead of the field of view itself being mechanically scanned) to recognize and decode the symbol. Because the angular orientation of the symbol is variable, this binary representation may be interpreted to determine how the memory array is to be scanned to recognize the bar code symbol. For example, the distinctive patterns of characters used in bar codes may be found by scanning the memory and the relative positions of these patterns interpreted to determine the position, size and shape of the symbol in the memory (20), thereby defining at what angular displacement the memory array need be addressed to traverse the rows of the bar code symbol. Or, the memory array may be simply scanned using preselected scan lines (beginning with a raster-type scan) until code recognition is obtained.
