Abstract: ABSTRACT    This invention related to methods of reading tachograph charts. Such carts are sequentially read by a chart-reading equipment to derive signals representative of the information recorded on the charts. In order to identify these signals information has been manually entered into the chart-reading equipment to identify the information provided on the respective charts, the chart-reading equipment provided in respect of each chart a respective signal having a first part representative of the corresponding manually-entered identity and a second part representative of the information recorded on that chart. The entering of said identities into the chart-reading equipment reduces the rate at which the charts can be read by the chart-reading equipment.     According to this invention the charts are provided with individual and different machine-readable representations and the chart-reading equipment automatically derives during the reading of the charts respective signals representative of the said chart representations to identify the corresponding said signals representative of chart information.      Such a method obviates the necessity of manually entering information into the chart-reading equipment and thereby permits the rate at which the charts are read to be increased.

Abstract: GAS TURBINE ENGINE GEOMETRY CONTROL Abstract of the Disclosure A single-shaft gas turbine engine suited for road vehicle propulsion has variable inlet and outlet guide vanes in the compressor of the engine and a variable turbine nozzle. These variable features are called engine variable geometry (EVG).  In normal operation, the areas of the flow paths at the inlet and outlet of the compressor and of the turbine nozzle are varied with desired power level to suit varying air flow through the engine.  An actuator increases the areas in response to a request for increased power output.           In a braking mode, the compressor variable geometry is decoupled from the actuator and remains at a minimum flow condition while the turbine nozzle is opened as the power request decreases below a particular low value.  The opening of the turbine nozzle decreases the engine power output, thus increasing its capacity to absorb power from the vehicle. Logic circuits control the coupling and decoupling of the compressor variable geometry.

Abstract: Control System for Selective Positioning of a Displaceable Device.                         ABSTRACT        A control system is disclosed for selective positioning a displaceable device, in particular the load carrying fork cage of a so-called fork-lift truck, into pre-selected positions or heights. The control system includes spaced apart pairs of associated switch elements, one element of each pair being mounted on a stationary guide, and the other element on the displaceable device. Each element pair defines one of the pre-selectable positions when the two elements are aligned, and in that ease they further assume an actuated condition. Each element pair is connected in series with a particular selector switch, and when both the selector switch and the element pair are in an actuated condition, a coupling device is ener-gized to cancel or reduce the load carrying ability. The displaceable device then sinks until the two elements of the actuated pair are separated, whereafter the displace-able device is kept stationary in a well defined position or height. The control system is semi-automatic, very simple and well-suited for mounting on already existing fork-lift trucks.

Abstract: ABSTRACT     A steel strip such as  stainless steel is passed in uncoiled form through a jet recuperator, an intermediate furnace section, and a main fired furnace section in which a fuel such as natural gas is burned. The exit end of the main furnace section has an opening only slightly greater than the cross-section of the strip. The strip is preheated in the jet recuperator by forcing waste gases from top and bottom waste gas chambers through holes in the bottom and top, respectively, of the waste gas chambers against both sides of the strip. The strip is further heated by the waste gases in the unfired intermediate section and brought to final temperature in the main fired section.

Abstract: ABSTRACT:          The invention provides a solution for the refreshing organization in a main memory with dyna-mic information storage. In the case of a memory matrix, for example, each row of bit positions is addressed by first sub-address signals, with the, result that a refreshing operation is performed for the complete information of the relevant row. With-in a row bit position is addressed by second sub-address signals. A second memory is provided which comprises one word position for each bit row of the main memory. The second memory has a comparatively short memory cycle. During the first half of the "slow" memory cycle, a word of the second memory is addressed by the first sub-address signals and is filled with predetermined information. During the second half of the "slow" memory cycle, each time a next word of the second memory is addressed by the position of an address counter. The word is read. The output register is constructed as a counter; the information read is raised by 1 and is written back. A carry output signal of the out-put register can reserve the next "slow" cycle of the main memory for the execution of a refresh-ing operation at an address of the main memory which corresponds to the position of the address counter.

Abstract: ABSTRACT OF THE DISCLOSURE          Individual line service features on a multi-party two-wire telephone network are provided by apparatus that interfaces individual subscriber stations with the network.  The apparatus includes a current sensor for detecting on hook and off hook modes of its station and a voltage sensor for determining the availability of the network to establish a bidirectional communication path with the station.  Control logic circuitry responsive to the sensors sets the apparatus to an active state when the station is off hook and the network is available and to a nonactive state when the network is not available.  Signal generators that are operably responsive to the control logic produce tone signals that indicate such states.  A relay operated by the control logic circuitry in response to the status of the apparatus then connects its station across the network in the active state and disconnects the station in the nonactive state.  Ringing signals on the network are detected and within one complete ring cycle are decoded.  This ensures privacy since each apparatus is respon-sive only to its own code.  Ringing voltage is then applied across the ringer of the called station.  A break-in feature permits intruding on a conversation in case of an emergency, but surreptitious eavesdropping is prevented by an intrusion signal that is placed on the network for all stations to hear.  Revertive calls between calling and called stations on the same network are performed by dialling the required number followed by a hook flash at the calling station which temporarily places the calling station in the nonactive state to free the network for ringing the called station until it goes off hook.  Should the network be determined as being busy, the station is returned to its on hook mode and a previously charged capacitor is dis-charged through its ringer to provide an audible alarm when the network later becomes available for use.
