Title: Hydraulic cylinder for an inboard/outboard propulsion unit
Inventor: NAKAMURA TAMOTSU
IPC: B63H20/10
Filed: 1982-08-13
Abstract: A hydraulic cylinder for an inboard/outboard propulsion unit of a motor boat or the like. The hydraulic cylinder has an outer tube (3), which is connected to the hull of the motor boat, and a piston (4) which is displaceably accommodated in the cylinder and is connected to the propulsion unit so that the propulsion unit can be tilted and fixed in any desired position in order to obtain the maximum propulsion effect when the boat is underway. So that the hydraulic cylinder can dampen and absorb the shock caused by a collision of the propeller with a submerged obstacle, the piston (4) is provided with several relief openings (7) which are normally closed by spring-loaded steel-ball non-return valves (9). A disc valve (18) of special construction is provided in the hydraulic cylinder in order fully to prevent the internal leakage flow of hydraulic oil through the non-return valve, as a result of which the undesirable change of the angle of inclination of the propulsion unit is prevented, which would otherwise be caused by the internal leakage flow. <IMAGE>

Title: Method for influencing the oil temperature of a machine or the like and machine or the like
Inventor: MAY MICHAEL G DIPL ING
IPC: F01M11/00
Filed: 1983-05-20
Abstract: Method for influencing the temperature of the intake oil of a circulating lubrication system of a machine or the like, which machine has an oil sump and an oil pump with an intake pipe having a suction mouth for sucking up oil situated in the oil reservoir of the oil sump. For a more rapid increase of the temperature of the oil sucked up by the oil pump following each cold start of the machine, at least during a part of the machine warm up phase which leads to the machine being heated up to operating temperatures, the inflow into the oil pump of heated oil returning into the oil sump from the lubricated machine parts is favoured, this method being so designed that in addition at operating temperatures of the machine it has the effect of evening out the temperature of the oil sucked up by the oil pump.

Patent DE-3339886-A1 (DE)
Title: Regulating the position of webs of material
Inventor: MATHES GERD
IPC: G01D5/34
Filed: 1983-11-04
Abstract: The invention describes a new method for regulating the position of hot (red-hot) webs of material, which does not use the red-hot web's own radiation for regulation, but rather sources of outside light or radiation which radiate in spectral regions which are substantially higher than the radiating region of the red-hot web of material. Regulation is not dependent on the width of the red-hot web, but on its shadow edges. This permits regulation of the position of webs which have only just entered and are still cold and also of red-hot webs.

Title: Spectrophotometer for recording a direct ratio
Inventor: MATSUI SHIGERU
IPC: G01J3/42
Filed: 1983-11-09
Abstract: A spectrophotometer for recording a direct ratio, in which a reference light, a reference side and a specimen light transit a specimen in order to enter a monochromator with the use of a sectored rotating mirror. The spectrophotometer detects the reference light and specimen light emerging from the monochromator, and sequentially calculates a ratio between the two light signals in order to obtain a spectrum. The wavelength scanning is performed for the monochromator in steps, so that a pair of reference light and specimen light following one another can emerge at the same wavelength. The one-stage wavelength scanning is performed during the period in which the reference light and the specimen light do not enter the monochromator.

Title: Method and apparatus for reducing the emissions of dangerous molecular substances
Inventor: BODE EVA PROF DR
IPC: B01D53/00
Filed: 1984-01-12
Abstract: In a method for reducing the emissions of dangerous molecular substances into the environment, especially emissions of dangerous gaseous substances into the ambient atmosphere, it is possible to achieve, with a low expenditure of energy, a substance-specific conversion of substances which are dangerous and not, or not easily, precipitable, into innocuous and/or easily precipitable substances, by irradiating, prior to the escape of a specific dangerous molecular substance into the environment, with radiation of a particular wavelength which is tuned to the molecular structure of the dangerous substance, as a result of which the molecules of the dangerous substance are selectively brought to a particular excited state and from this excited state decompose into molecules or atoms of innocuous and/or easily precipitable substances, or bind to molecules or atoms of simultaneously present other substances to give molecules of innocuous and/or easily precipitable substances. Expediently, the wavelength of the radiation is in the range of the long-wave end of the spectrum of visible light up to the middle infrared and/or in the range of the short-wave end of the spectrum of visible light up to the near ultraviolet. In any case it is particularly expedient to generate the radiation of a particular wavelength by means of a preferably wavelength-tunable laser. The invention also relates to a corresponding apparatus.
