Furthermore, the invention relates to a method for producing the BAW filter.

Abstract: The invention relates to a filter arrangement (10) comprising a substrate (16) having a first series resonator (11) and a first and a second parallel resonator (12, 13). The filter arrangement (10) further comprises a carrier (18), on which the substrate (16) is arranged and which comprises a first inductor (17), the first connection of which is coupled to a first connection of the first series resonator (11) by means of the first parallel resonator (12) and to a second connection of the first series resonator (11) by means of the second parallel resonator (13).

Abstract: A ladder-type-like filter circuit is specified with improved filter behavior. Inductive elements that interconnect parallel resonators with ground are electromagnetically coupled to one another.

Abstract: The invention concerns a control system for operating a drive assembly of a ship. The system consists of an engine (1), a transmission (3) and an adjustable clutch (4) for forward and reverse motions. A control station (15), a control lever (27) and a control electronics (15) are provided for adjusting the direction of motion and the speed of the ship. In order to influence the reaction of the ship when changing direction, several reversing aids are provided according to the invention. The pilot can use the reversing aids by actuating a selection key (24) located on the control station.

Abstract: The invention concerns a control system for operating a ship's motive installation (1, 2). Via a gearing (4) having adjustable clutches (67, 69) for forward and astern movement, an engine (3) drives a propeller shaft (7). Control and sensor devices (53, 54) are provided. With them the engine speed and the degree of slip of the clutches can be altered. With a control lever (13, 14) of a control post (9) a propeller shaft speed can be adjusted. A control electronics (21) defines the momentary operational condition by freely selecting from three possible operation conditions. The respective operation condition is defined depending on operational parameters to be observed of the engine (3) and/or the gearing (4). The control system is particularly adequate for use within a ship's multi-engine motive installations.

Abstract: A device for the thermal treatment of organic substances and of inorganic substances contaminated with organic substances which makes a high throughput possible. The reactor contains several bottoms provided with perforations with ceramic ball sections which can be moved separately.

Abstract: Subterranean cavities which can be filled with water or brine are also used for safely depositing ecologically harmful waste. In order to introduce the waste, which must not come in contact with the water or brine, a liquid which is not miscible with water and is specifically heavier than water or brine is let in below the water or brine, where it forms a layer, and the waste is introduced into this liquid via a pipeline, whereby the waste or the mixtures of waste and binding agents must be specifically heavier than the liquid. The displaced water or brine is upwardly removed.

Abstract: Halogenated hydrocarbons are reacted in a reactor at temperatures up to 1000.degree. C. with greater-than-stoichiometric amounts of calcium and/or magnesium silicates in a reactor for the chemical-thermal degradation of the halogenated hydrocarbons. Neither dioxins nor furans are formed in the waste gas in this process.

Abstract: A halohydrocarbon is destroyed chemical-thermally by reacting at 600.degree. to 800.degree. C. with calcium oxide and/or calcium hydroxide. The process can be carried out problem-free by having the calcium oxide of hydroxide present in at least twice the stoichiometric excess based on the halogen to be bound and by having the composition contain 2-30 wt. % iron oxide.

Abstract: A transmission is disclosed for use in ship drive arrangements. The transmission comprises a gear train having three main axes inclined and in parallel with respect to each other. The gear wheels of the gear train are selectively coupled to the main axes to transfer motive power from the input side of the transmission to the output side. The system affords space saving arrangements depending on the type of motor that is employed for the drive assembly.

Abstract: A dual hydraulic clutch with two operating positions and an intermediate neutral position receives pressure fluid through a three-position selector valve communicating with a pair of piston cylinders which are alternately under high and low fluid pressure in operation and are both under low pressure in neutral. Shifting the control valve partly unloads one of the cylinders into a throttled discharge line with generation of a pressure drop therein to actuate a bypass valve for instantly lowering the pressure in a supply line; the disappearance of this pressure drop upon termination of shifting gradually recloses the bypass valve for progressively raising the supply pressure to its operating level.
