  • Process for determining the percentage of combustible gases in a gas mixture as well as their classification according to gas class factors
    Patent number: 5513125
    Abstract: In a process for determining the percentage of combustible gases in air by means of a detection element catalytically supporting the combustion, this detection element is heated with an excitation function according to a predeterminable current-voltage pattern, and the response function resulting from this is investigated with respect to the position of its maximum (differentiation). If a time interval limit (3) is exceeded by the maximum, a first gas type factor is sent to the evaluating circuit, and if the maximum does not reach the interval limit (3), a second gas type factor is determined and is evaluated as a calibrating value and for the classification of the combustible gases to be investigated.

  • Centralized multichannel fluid delivery system
    Patent number: 5507412
    Abstract: A multichannel metering system, for metering preselected fluid flows from individual fluid flow sources, includes a control device, and data fields which are located in the control device (memory) and describe at least the metering of the individual fluid flows, and can be polled to an operating surface connected to the control device with a data input circuit and with a data output circuit. The data field associated with a fluid flow source can be selected in a simple manner using selector switches associated as part of the data input circuit with individual fluid flow sources by which selector switches at least segments of the fluid flow source belonging to the fluid flow source selected can be represented on the operating surface. At least part of the data input circuit are switched into functional connection with the data field belonging to the fluid flow source selected.

  • Bulk material loading and unloading facility for sea-going ships
    Patent number: 5501563
    Abstract: A bulk material loading and unloading facility for sea-going ships with displaceably arranged bulk material loading and unloading devices (23). Instead of a pier or a dock facility and a shore-side storage facility equipped with stackers and reloading devices and the conveyor belt units needed for them, a trough-shaped bulk material storage facility (14) is arranged on the ocean bottom (3) at a water depth that is safely navigable for sea-going ships, and rails (22) are laid on the side walls (15) of the bulk material storage facility. Loading and unloading devices (23) travel on these rails, and the loading and unloading devices (23) convey bulk material from ships (28) into the trough-shaped storage facility (14), or onto a conveyor belt unit (25) leading from this storage facility directly to a bulk material processing facility (e.g., a coal-fired power plant).

  • Method and device for recognizing decoys serving to disguise a target with the aid of an active search head
    Patent number: 5501413
    Abstract: A guided missile is directed toward a ground level or sea level target despite the presence of laterally and vertically offset decoys by causing the missile first to "acquire" one of the target or decoys. The guidance system then directs the missile in the azimuth plane toward the acquired target while it directs the missile along a predetermined path that ends in a low level horizontal flight. A simulator simulates a flight path toward the acquired target in the elevational plane. When the simulated flight path toward the acquired target deviates from the predetermined elevational path by a preset amount, a logic system causes the missile to unlock from the target and acquire a new one. Thus the missile will ultimately only lock onto the sea level or ground level target.
