Inventor: GOHARA W F
IPC: F22B37/10
Filed: 1986-05-29
Abstract: An expansion joint is provided between the bottom supported tube walls and the top supported tube walls of a fluidized bed boiler furnace. The expansion joint includes an upwardly open trough having one side and a floor defined by bent portions of the bottom supported tube wall, and another side wall defined by a refractory lined steel plate. A knife edge or sealing projection is connected to an outwardly bent portion of the top supported tube wall and extends downwardly through the upward opening of the trough and into the spaced defined by the trough. The trough is filled with sand or other inert granular material which partially covers the knife edge. The knife edge is in the form of a tube wall with tubes having lower perforations. Fluidizing gas can be supplied into the knife edge to fluidize the sand around the lower end of the knife edge to permit movement of the knife edge in the sand as the top and bottom supported tube walls expand. A satisfactory seal is provided by maintaining a suitable height of the sand covering the knife edge.

The bridge comprises two transistors including flywheel diodes and connected in series between positive and negative power supply rails for conducting current to or from the load under control of a control drive circuit. An LC-circuit is connected between the bridge circuit and the load. The bridge voltage (E) of the connection between the two transistors and the current (I) through the inductance of the LC-circuit are monitored and a firing pulse is supplied to one of the transistors. When the current (I) through the inductance exceeds a preset value (I'), the transistors is turned OFF, whereupon the current of the inductance continues to flow another way through the flywheel diode of the opposite semiconductor member and consequently the bridge voltage (E) changes polarity a first time to the opposite rail polarity until the magnetic energy of the inductance has been terminated resulting in a second change of polarity of the bridge voltage (E) towards the first rail polarity. The change of the polarity of the bridge voltage (E) towards the first rail polarity is detected and another firing pulse is supplied at or shortly after said change.

Abstract: In a vehicle combination consisting of a hauling truck (1) and a semitrailer (2), the brake system of the hauling truck (1) comprises a valve (8) which allows the brake pressure supplied to the brakes of the semitrailer (2) to be adapted to the brake pressure supplied to the brakes of the hauling truck (1). The adaptation is carried out by means of an electronic control unit (16) in which the actual deceleration of the vehicle combination during a braking sequence is compared with an anticipated deceleration. In the event of discrepancies between these decelerations, a control valve (23) is actuated, whereupon the valve (8) is supplied with a pneumatic signal which ensures that the semitrailer (2) is supplied with a higher or a lower brake pressure relative to the hauling vehicle (1), depending on whether the actual deceleration was lower or higher than the anticipated deceleration.

Abstract: Release is carried out by PP transmitting CC-RELEASE COMplete. The invention thus entails that a person who belongs to a radio system with a short range, for example a wireless telephony system, can be temporarily transferred as guest into a second wireless telephony system. When the user moves to a second communications system, he identifies himself in it as a guest. Information relating to the temporary address of the relevant person is transferred to his home system. An incoming call to the person in question is received by the home system which forwards the call to the system in which the person sought is temporarily registered. The caller is then notified that a call is coming in by a call signal being originated. The called party then answers the call and a normal call is set up. With the outgoing call, signals are transferred from the caller to means in the network which register who is establishing the call. The registration is carried out on the basis of a call occurring from a certain subscription, or person, regardless of whether the call is established from the home system or as guest in another system. The system then registers the length of the call and debits the subscriber at his home address. <IMAGE>

Abstract: The arrangement is for the protection of buildings from water damage in the event of flooding and uses a foundation base (A), a number of control rail constructions (B) built together with the foundation base, a floating body (C) which can be built together with the house, a connecting cabinet (D) for service conduits, and a mooring device (E). The floating body with the housing floats on the surface of the rising water whilst the remaining components and parts are immersed in the water. As the water rises, the house is raised vertically from the foundation base, and the service conduits in the cabinet are automatically disconnected when the water has reached a specific level. Whilst the house rises it is guided vertically by the control rail constructions and the mooring device. When the water level drops, the house with the floating body slides downwards along the control rails and comes to rest accurately on the foundation base.

Abstract: In an industrial vacuum cleaner with bag filters are used screw wound distension elements (22) for the filter bags (20). These elements are made as relatively soft springs, which, in operation, will be compressed if filter cakes (30) are formed on the bags, as this will cause an increased air pressure at the exterior dust side of the bags. However, in return the bags will be expanded by a noticeable movement each time the cleaner is stopped, this promoting a rejection of the filter cakes. This effect may be amplified by a sudden opening of a wide valve (34) in the wall of the suction chamber (26) above the filter bags, as the springs will be then straightened out almost impact-like by the associated rapid pressure increase in this chamber.

When the internal combustion engine is operating in a transitional state, for example, when the engine is accelerating or decelerating, a fuel injection control mode suited for the transitional operating state is selected preferentially over the mode selection for a steady state by a fuel injection control mode switching means. Consequently, the fuel injection control apparatus permits desirable operation of the internal combustion engine, making it possible to greatly improve the drivability of a vehicle in which the engine is installed.
