Patent SE-8005344-L (SE)
Inventor: PECHACEK C
IPC: B60W10/04
Filed: 1980-07-23
Abstract: The circuit is intended to be substantially independent of variations of ambient temperature, with the possibility of achieving a low hysteresis without danger of generating oscillations particularly at "kick-down" conditions, whereby switching points at "zero gas" are not shifted due to hysteresis in dependence on the position of a control element of fuel supply. A vehicle speed signal is applied through a resistor R1 to the non-inverting input of an amplifier 2 the output of which controls a ratio shift switch 3. The inverting input of the amplifier is connected to a reference voltage divider and to the collector of a transistor T the emitter of which is connected to a potentiometer P coupled with the engine fuel control 4. The base of the transistor is connected to the output and to the non-inverting input of the amplifier and also to a kick-down switch S. <IMAGE>

Abstract: The invention relates to a device and a process for the selective variation of the compression ratio of an internal-combustion engine according to the engine load. The device comprises, in the cinematic control chain 34 of each intake valve (2), a means (10) causing the intake valve to close before the normal closing moment after bottom dead centre and governed by the current load of the engine so as to function only under low loads; and a means (11) considerably extending the opening period of each intake valve beyond the normal closing moment after bottom dead centre by preventing it from closing completely at this moment and taking action only under high loads. This device makes it possible to improve the performance of internal-combustion engines. <IMAGE>

Abstract: A method in the transportation of viscous or non-flowing, liquid-containing pulp, such as papermaking pulp, peat sludge and the like, through a conduit while using a pump arrangement connected to the inlet end of the conduit. In accordance with the method, liquid forced from the pulp as a result of the compression forces to which the pulp is subjected when generating the requisite pump pressure is led away, and at least part of this liquid is supplied to the outlet of the pump, between the surface of the pulp exiting in plug form and the inner surface of the conduit. The pump arrangement suitably has the form of a screw pump having a part which converges conically in the pulpfeed direction, this part of the screw pump being surrounded by a casing having the form of a screen through which water pressed from the pulp is led away. The application also relates to apparatus for carrying out the method.

Abstract: A subscriber communication system includes a base station in a network with a plurality of subscriber stations, wherein control information is communicated between the base station and the subscriber stations over a radio control channel (RCC) at a frequency selected by the base station from a plurality of predetermined frequencies. The a base station transmits control messages including a unique network number over the RCC. Each subscriber station processes the network number in the control message received over the RCC to enable the subscriber station to process the control message in accordance with whether the subscriber station is in the same network as the base station. The timing of communications transmitted by a subscriber station over a given communication channel between a base station and the subscriber station is refined upon initial establishment of the communication channel. Both DC signaling information and voice data signals are communicated over an assigned channel between a line appearance that couples a base station to a central office and a line interface that couples a subscriber station to a subscriber terminal.
