Patent EP-0124239-A2 (EP)
Inventor: HILL WILLIAM FRANK
IPC: F02P3/05
Filed: 1984-03-22
Abstract: An internal combustion engine ignition control includes a variable reluctance pick-up with a winding (14) providing signals to an integrator (Q<sub>2</sub> Q<sub>4</sub> R<sub>2</sub> C,) the output of which controls an ignition switching circuit (Q<sub>19</sub>). The ignition switching circuit includes a current limiter circuit (Q<sub>11</sub>) which operates to limit the coil (18) current at a maximum level until the instant of ignition. A capacitor (C<sub>2</sub>) is charged and discharged under the control of the current limiter circuit so that the voltage on it depends on the ratio of the time for which the current limiter circuit is in operation to the ignition cycle duration. An active clamping circuit (Q<sub>5</sub> Q<sub>6</sub> Q<sub>7</sub>) operates to override the integrator under the control of this capacitor (C<sub>2</sub>) so as to apply a variable preconditioning bias to the output of the integrator which has the effect of varying the instant at which the coil current is switched on. Closed loop dwell control is thus provided in a simple and convenient manner.

Abstract: In automatic assembly, components are often required to arrive at a delivery point in a sequence of different types and orientations. The invention provides a flexible and easily set up arrangement forthis purpose by projecting a beam of light from a laser 2 on to components 10 being fed towards a delivery point by a bowl feeder 1. Scattered and reflected light from the objects is received by a phototransistor 4 and the form of the output from the phototransistor is used to operate a valve which controls airflow through an orifice 11. The form of this output is processed to indicate whether it resembles forms corresponding to known components and orientations and if it indicates that a required type of component in a required sequence and orientation is passing along a track section 7 to the delivery point the valve is closed. Otherwise components are blown back into the bowl of the feeder by air from the orifice 11

IPC: G06T11/20

Abstract: @ The present invention includes a microprocessor (15) which acts to generate rasters of its signals from its read only memory (ROM), thereby forming character representations of groups of coded signals, such as ASCII coded signals, coming from a main data processing device. The rasters of bit signals are temporarily stored in a buffer (23) which at a subsequent time transmits, in parallel, groups of said bit signals to a bit map memory (33) through logic circuitry. The group, or block, transfer of these bit signals in parallel occurs during horizontal or vertical blank periods. The parallel transfer during the blank periods provides part of the basis for acceleration of the transfer of data to a display device as compared with the prior art. In addition, the microprocessor provides address information signals to a graphic display controller (19), which in turn provides starting addresses for the location of the bit signals. In addition, a bit map memory device is employed to provide pixel information to a CRT display device (51) to create the characters to be displayed.

Abstract: A set-up method for unequal speed circumferential rolling. The setting values of the circumferential speeds (V<sub>RL</sub>, V<sub>RH</sub>) of a higher speed roll (2) and a lower speed roll (1) and the roll position (S) and obtained by using, as rolling parameters in a rolling schedule, the inlet and outlet thicknesses (H, h), the forward and backward tensions (t<sub>f</sub>, t<sub>b</sub>), the radii (R<sub>L</sub>, R<sub>H</sub>) of the rolls (1, 2), the frictional coefficients (µ<sub>L</sub>, µ<sub>H</sub>) and the ratio of the circumferential speeds (V<sub>RL</sub>, V<sub>RH</sub>) of the rolls (1, 2). The setting values are computed such that these values meet the rolling conditions within both the load limit value and the tension limit value.

Abstract: Chemical heat amplification is provided in thermal transfer printing, wherein some of the heat necessary for melting and transferring ink from a solid fusible layer in a ribbon to a re- ce i ving medium is provided by an exothermic reaction. This chemical reaction is due to an exothermic material that is located in the ink layer, or in another layer of the ink bearing ribbon. The exothermic reaction reduces the amount of the input power which must be applied either electrically or with electromagnetic waves. Examples of suitable exothermic materials are those which will provide heat within the operative temperature range of the ink, and include hydrazone derivatives which are substantially colorless, and have a molecular weight in the approximate range 150-650. The group consisting of substituted aryl sulfonyl hydrazones, mono hydrazones of acylic -diketones, aromatic disulfonyl and diacyl hydrazones, and mono hydrazones of cyclic -dicarbonyl heterocycles are usable exothermic materials.

IPC: H04B3/06

Abstract: @ A data receiving system for digital data communication is described which uses asynchronous sampling and language interpolation or prolate spheroidal function on the received signal. A received analogue signal is first asynchronously sampled (22), digitised (26), stored in memory (28) and then processed using interpolation techniques to recover the correct symbol timing of the symbols in the digitised data. The minimum sampling rate commensurate with channel band width is used. The correct symbol timing is continuously adjusted within certain predetermined limits of the interpolation interval using a "jumping" algorithm which permits continuous symbol recovery. The recovered symbols are then equalised (40) to compensate for distortion and decoded (44) to give the originally encoded data. When bursts of data are being transmitted the data stored in memory (28) is replayed to ensure that all data in the data burst is used for communication and that there is no transmission overhead requiring extra symbols for synchronisation. In one embodiment the received signal is used to generate real and imaginary components (32,34) which are then subjected to interpolation (36,38) and, the interpolation is controlled using a digital filter and algorithm which optimises filter coefficients to recover the symbol timing.

Title: Local area network
Inventor: ARANGUREN WILLIAM LOUIS
IPC: H04L12/44
Filed: 1986-03-13
Abstract: 0 A modular, hierarchical local area network is realizable by using existing twisted pair wiring, for example, in a building together with several elements known as network access units and hub units. A network access unit is connected to a device (microprocessor, display terminal, peripheral device, other local area network, information systems network or the like) in the local area network to give that device access to and from the network. The network access device is designed for simple daisy chaining with other devices to form a node 210-1, 210-K when devices are colocated in the same section or room in the building. The hub unit 230 is the network building block which permits extensive expansion of the local area network. It provides a connection point for access units or other hub units, performs collision detection operations, if necessary, and serves as a loopback point for the network. 
     Switchably connectable termination impedances and loop-backs are automatically passed to the appropriate points in the local area network. 
     While most small local area networks are considered for intra-building applications, the present network is applicable to inter-building applications, also.
