  • Patent number: 10728776
    Abstract: In one embodiment, an emergency configuration control device is provided for a communications system that provides wireless RF communication service to a coverage area, wherein the system comprises an RF protection function coupled to at least one power amplifier, protection function configured to disable the power amplifier when the protection function determines that at least one parameter of the power amplifier has deviated outside of an operating specification, the device comprising: an emergency configuration control module executed by a controller, the emergency configuration control module configured to determine when an emergency event is occurring within the coverage area as a function of a first set of input signals; wherein the emergency configuration control module enters phase one operation and inhibits disabling of the power amplifier by the RF protection function and outputs one or more phase one notification signals in response to determining that the emergency event is occurring.

  • Publication number: 20200166131
    Abstract: A parking lock for a transmission of a motor vehicle may include a park gear rotatable about an axis of rotation, and an actuation device adjustable into a locking position and an unlocking position radially relative to the axis of rotation. In the unlocking position, rotating of the park gear may be possible, and in the locking position, rotating of the park gear may be prevented by way of positive locking. The actuation device may include a shifting drum and a locking lever, wherein the shifting drum may be rotatable about a guiding axis that is radial relative to the axis of rotation. The locking lever, by way of a guide track formed in the shifting drum, may interact with the guide track so that when the shifting drum is rotated, the locking lever may be guidable by the guide track radially relative to the axis of rotation and parallel to the guiding axis, and thereby the actuation device may be adjustable into the locking position and into the unlocking position.

  • Patent number: 10484138
    Abstract: A first communication subscriber transmits a first data packet comprising data and an identification character to the second communication subscriber. The first communication subscriber and the second communication subscriber respectively determine a first and a second acknowledgement character on the basis of the identification character. The second communication subscriber transmits a second data packet comprising the second acknowledgement character back to the first communication subscriber. The first communication subscriber can thus check, on the basis of the second acknowledgement character, whether the first data packet arrived at the second communication subscriber.

  • Patent number: 5267694
    Abstract: A fuel injection nozzle for internal combustion engines having a nozzle body secured on a nozzle holder, and a valve needle that is axially displaceable in the nozzle holder, the valve needle being raised from a valve seat for fuel injection by the fuel pressure, counter to a closing spring assembly of first and second helical compression springs disposed in series. The total stroke of the valve needle is divided into a prestroke and a remaining stroke. To attain an injection nozzle having the smallest possible outside diameter, the spring chamber receiving the closing springs comprises a blind bore of substantially constant diameter, on a bottom of which the first closing spring is supported. To support the second closing spring, a pressure shoulder part in the form of a ring is inserted into the blind bore; the pressure shoulder part is fixed by deformation of contacting parts of the wall of the nozzle holder.

  • Patent number: 5061119
    Abstract: A method for the remediation of contaminated soils, in which, without transport of the soil to the surface, a loosening of the soil structure is achieved by progressively injecting a liquid under high pressure into at least one cylindrically shaped soil body. Besides loosening the soil the liquid also serves as a carrier and transport medium for at least one effective substance, which decomposes and/or converts the respective contaminant on site. By this method, the effective substances are uniformly distributed in the soil treatment zones and reach the contaminants even in heterogeneous soil structures.

  • Patent number: 4543184
    Abstract: A cake filtration apparatus in a structural unit which comprises a plate filter and a filtering aid-dosing device which includes an agitator. The drive parts for rotating the filter unit are disposed on the top wall of the filter housing, and are connected with the drive of the agitator by means of a transmission device and a freewheel coupling. The shaft of the filter unit is only sealingly and rotatably mounted in the vicinity of the bottom of the housing. The bottom plate, the height of which is adjustable for removal of the centrifuged filter cake, is constructed in the manner of a disk valve having a valve seat, and can be raised and lowered independently of the filter unit, so that for centrifuging and removal of the filter cake, the filter unit no longer has to be raised or in some other manner moved out of its operating position.

  • Patent number: 4473964
    Abstract: A recoilless competition rifle or competition pistol with an action which is mounted and guided in the firearm so as to be longitudinally displaceable on bearings and which returns during firing. The bearings have special beddings which compensate for deviations of the bearing axes from their ideal desired positions by adapting their shape to the particular conditions. Bearings made of elastic materials provide for a reversible displacement of material. Beddings comprise materials which can be poured or kneaded and which then solidify in situ to assume their final form as a result of direct shaping (initial shaping) on the delimiting surfaces.
