Title: Control device for the mixture composition of an internal combustion engine operated with gaseous fuel
Inventor: RAFF LOTHAR
IPC: F02D41/14
Filed: 1983-06-14
Abstract: A control device for the mixture composition of an internal combustion engine operated with gaseous fuel is proposed in which the output signal of a single oxygen probe which has an increment in the range of  lambda  = 1 and a constant signal response in at least one of the marginal ranges is evaluated, according to the operating state of the internal combustion engine in the incremental range ( lambda = 1) or in the constant signal range ( lambda  > < 1) for controlling the air-gas mixture. Various control concepts can be realised using this device, it being possible, in particular, to switch between the two control concepts with adjustment to minimum pollutant emission or adjustment to minimum fuel consumption as a function of operating parameters of the internal combustion engine. For the adjustment to minimum pollutant emission, the incremental response of the lambda probe for  lambda  = 1 is used, whereas for the adjustment to minimum fuel consumption a constant adjustment on the lean-branch of the characteristic curve of the lambda probe is performed for lambda in the range 1.2 </=  lambda  </= 1.8. <IMAGE>

Title: Method and device for cutting fish open, even those of different sizes, especially trout, by machine, and for removing the innards
IPC: A22C25/14
Filed: 1983-08-02
Abstract: In a method and a device for cutting open fish, even those of different sizes, especially trout, by machine, and for removing the innards, the fish (8), with their bellies pointing upwards and their heads in front, are successively moved on a conveyor (5) which is provided with reception devices, the throats of the fish are cut transversely to the longitudinal direction of the fish, the belly is cut open longitudinally from the transverse cut to the anus and then the innards are removed. So that even fish of different sizes can be killed individually without damage, the fish (8), depending on its size, is given a cut in the shape of an obtuse angle pointing in the conveying direction in its throat region, and the belly is cut open at a height above the conveyor (5) which depends on the size of the fish. The belly flaps formed in this way are folded outwards, and then the fish (8) is cut in two in the gullet region, in a vertically adjustable fashion, and the innards are sucked out of the folded-open belly in a vertically adjustable fashion, using sub-atmospheric pressure. Then the renal skin of the fish is slit slightly and the kidneys are washed away by water under pressure and the belly cavity is simultaneously rinsed out. <IMAGE>

Patent DE-3339428-A1 (DE)
Title: Signal comparison protection system for monitoring transmission paths of the supply network
Inventor: SCHEIDER MANFRED DIPL ING
IPC: H02H3/05
Filed: 1983-10-29
Abstract: The invention relates to a signal comparison protection system for monitoring transmission paths of the supply network, a reference signal being transmitted over additional lines in parallel with the network transmission, and disturbances in the network being identified with the aid of the comparison between network and reference signals. The object of achieving the maximum possible operating reliability at a low cost is achieved in that a frame is formed for the reference signal which is to be transmitted digitally, such that each useful word has a synchronising word of equal magnitude placed before or after it. At the receiving end, the two synchronising words are then checked in a simple manner and transmission errors are confirmed in quasi-real time so that erroneous disconnection of the network is prevented.

Title: Method and apparatus for processing liquids, in particular liquid manure
Inventor: HUMPEL ANTON
IPC: B01F5/04
Filed: 1983-12-09
Abstract: In the process according to the invention, liquid is converted, prior to mixing with the preferably gaseous processing components, into a gaseous state, in which the processing components are added. After the mixing of the evaporated amount of liquid with the processing components, the vapour of the liquid is reliquefied and mixed with the remaining amounts of liquid which have not been evaporated, as a result of which a very high proportion of gas in the gas mixture remains in solution. The apparatus (1) according to the invention has a pumping device (2) and a nozzle (8) of a mixing device (19), which, in order to generate a cavitation region (16) in a mixing element (10), have a common interaction region which is essentially provided in the central region of the liquid flow. The apparatus (1) further comprises a flow connection between an inlet line (13) for processing components and the cavitation region (16). This makes it possible to draw in the processing components as a result of the reduced pressure prevailing in the cavitation region (16) and then to mix the preferably gaseous processing components with the liquid evaporated in the cavitation region (16). <IMAGE>

Title: Control system for a pneumatically operated cylinder/piston arrangement
Inventor: FRIES WALTER
IPC: C10B41/08
Filed: 1984-02-01
Abstract: The control system for a pneumatically operated cylinder/piston arrangement has a piston which can be acted upon on both sides by compressed air and a work arm which is linked to the piston rod and crosses a dead centre. Attached to the cylinder on both sides of the piston are compressed-air lines which can be connected to a compressed-air source via a control valve. Both compressed-air lines are connected to the compressed-air source when the control valve is in the neutral position so that the piston is always acted upon on both sides by compressed air. When the piston is working, the compressed air in the cylinder space arranged upstream in the working direction escapes only slowly via the choke arranged downstream of the control valve so that a damping effect is obtained. Furthermore, the control system according to the invention guarantees that the work arm can still be moved manually or mechanically by an acting adjusting device. <IMAGE>

Title: Method for mixed-light exposure in still cameras
Inventor: BRAEUNING GERHARD
IPC: G03B7/16
Filed: 1984-02-08
Abstract: A method for mixed-light exposure in still cameras with built-in flashguns is specified, each photograph being taken using flashlight. The exposure is performed in two stages, flash exposure being performed in a first stage with a small camera aperture and exposure with environmental light subsequently being performed during one and the same photograph in a second exposure stage with a larger camera aperture. In the case of the smaller camera aperture, the depth of focus extends as far as into the near zone, so that the near zone, in particular, is sharply imaged by the flash exposure, and this also has a particularly advantageous effect with interior photographs. The larger camera aperture further provides a sufficiently short shutter speed for imaging the picture background by means of the ambient light. <IMAGE>

Title: Sheathing for cable routes
Inventor: KRAUSE RUDOLF DR ING
IPC: H02G3/04
Filed: 1984-12-12
Abstract: The invention relates to a sheathing system for cable routes, with the aid of which, especially, cable routes which run in buildings are enclosed for protection against fire damage. According to the invention, mineral-wool panels are provided in order to form the sheathing, which panels are coated at least on the outer sides with a means for forming an insulating layer and, over said layer, with a noncombustible coating material. Such panel elements are considerably lighter than the calcium-sulphate panels which have been used for this purpose until now. The sheathing according to the invention thus leads to advantages particularly with respect to easy installation capability and high safety with respect to earthquakes. In addition, there is no longer any need for special protection for the separate suspension devices of the sheathed cable racks.
