Inventor: LEIBER H
IPC: B60T13/14
Filed: 1983-04-27
Abstract: A control valve for the application of a desired pressure in a working circuit, having a pressure chamber connected with a pressure source, a control chamber separated during the rest position of the valve from the pressure chamber by a first seat valve which connects with a working circuit and a pressureless connection during the rest position of the valve, and finally the control valve has an activating piston 14, by means of which, when the control valve is operated, first the connection between the control chamber and the pressureless connection is interrupted and then the first seat valve is opened. Additionally, a further seat valve is interposed into the connection between the pressure source and the pressure chamber, and a control piston 7 is provided to open seat valve 6 when exposed on the one side to the pressure in the pressure chamber 9 and on the other side to the pressure applied in the working circuit. The surface of the control piston exposed to the pressure in the pressure chamber is, in contrast to its surface exposed to the pressure in the working circuit, dimensioned so much smaller and/or the spring 11, acting on the piston and supporting the pressure in the working circuit is dimensioned in such a way, that this further seat valve, on the one hand, is closed during a state of no-pressure in the working circuit, however, on the other hand, during the opening of the first seat valve and the increase of pressure in the working circuit connected therewith, the control piston is displaced in such a manner that the further seat valve is opened.

Abstract: A procedure for processing hard, brittle materials with little tensile strength in proportion to compressive strength, e.g. rock, boulders or concrete. To achieve cracking of the material (1), one or more holes (2) are made in the material, and a cooling agent (3) consisting of a liquid-cooled gas etc. is introduced into these holes. This creates the rapidly cooled zone (4) in the hole (2) and the contraction in the zone causes the cracks. These emanate depending on the location of the holes (2) in relation to the constraining areas of the material (1) from the hole's (2) enveloping area (2'), the constraining area of the material (1) situated the near the hole between two or more holes or adjacent to the border section between the cooled zone (4) and the material (1) with a higher temperature.<IMAGE>

Abstract: The present invention relates to a method for unthrottled load control of an internal combustion engine by means of exhaust gas. The method requires entirely freely adjustable opening and closing times for the inlet and exhaust valves. Starting at full load with the minimum of exhaust gas in the cylinder the amount of exhaust gas in the cylinder is increased thereby reducing the available combustion chamber volume for receiving fresh mixture mass thereby reducing the load. The fresh mixture mass and the exhaust gas mass are controlled exclusively by coordinating the opening and closing times of the intake and exhaust valves.

Abstract: A system for controlling the ignition timing of an engine provided with a supercharger. The system comprises a vacuum advance device comprising two chambers defined by a diaphragm and a rod connecting the diaphragm to an advance mechanism of a distributor of the engine. The vacuum advance device is operated by the difference between the pressure at a signal port in the intake passage at an upstream side of the throttle valve of the engine and the pressure at a signal port provided in the wall of the intake passage at a position just above the throttle valve, the pressure thereat varying with the variation of the opening degree of the throttle valve. The vacuum advance device is so arranged as to retard the ignition timing at high engine speed by the pressure difference.

Abstract: The disclosure relates to a method of producing bottle or tube-like, capped packages from a polymer material which is plastically formable in the heated state. In the forming operation, a sheet (7) of polymer material heated to plasticity is fixedly clamped over the aperture (2) of a conically shaped cavity (1) corresponding to the form and size of the produced packaging container. The plastic sheet (7) is pressed into the cavity (1) by means of a mandrel (9) at the same time as blades or vanes (10) supported by the mandrel (9) are folded out in the radial direction from the mandrel (9) and urge the plastic polymer material against the walls (3) of the cavity (1), the walls being provided with channels or slots which may be placed in communication with a vacuum source. The forward portion (11) of the mandrel (9) forces parts of the polymer material into a cap (5) disposed in the innermost region of the cavity (1), with which cap the polymer material can be united. Finally, the hollow body (4) formed from the polymer material is removed from the cavity (1), filled with its intended contents and sealed by means of a preformed bottom portion (12).

Abstract: The present invention relates to a method and an arrangement for channel allocation in a radio communication system in which data is transmitted between two stations over two or more radio channels. Data is communicated as packets which are divided into blocks while the transmission follows a protocol for automatic re-transmission of data that have been erroneously transmitted. In accordance with the proposed method, channels for re-transmission are allocated with respect to a transmission parameter which has been created at a previous transmission and which is based upon information of the result of said previous transmission. The transmission parameter is aimed to ensure that re-transmission is performed via those channels which have the highest probability of transmitting data correctly. The channels which had the highest transmission quality in said previous transmission are expected to have the highest transmission quality also by re-transmission.
