Title: Noise protection wall comprising double-glass elements
Inventor: CZINKI LASZLO DR
IPC: B44C5/00
Filed: 1993-09-13
Abstract: A noise protection wall which is variable and satisfies different requirements consists of a supporting construction, for example upright supports, between which there are arranged wall elements consisting of a multiple-glass construction. Between the individual glass plates there is introduced a filling composed of different components or mixture components which is either preset or changes in accordance with the particular influences. The latter is achieved by the fact that constituents which are differently coloured or also have different particle sizes are held in a liquid, a change in the appearance predetermined by the mixture also being achieved by turning the entire glass plate. A considerably greater acceptance together with optimised noise protection is the result of a noise protection wall constructed in this fashion. <IMAGE>

Title: Piston cooling of an internal combustion engine
Inventor: WAHNSCHAFFE JUERGEN DIPL ING
IPC: F01M1/08
Filed: 1993-09-17
Abstract: In addition to a cooling duct sunk into the piston, a known piston cooling for a piston of an internal combustion engine has a spray nozzle which, comprising a plurality of components, is fixed as a separate part to the crankcase and is charged with oil from a separate oil supply line. After assembly, the said spray nozzle must be precisely aligned, using a special tool, with an opening for the oil supply of the cooling duct. According to the invention the manufacturing/assembly process is shortened and the cost of adjustment is reduced in that the oil emerges through a spray opening 11 arranged directly in a wall of the crankcase or the cylinder tube, and that the inlet opening into the cooling duct 7 has a collecting funnel 8 geometrically matched to the spray jet 11a. At the same time the spray opening 11 is not arranged precisely below the collecting funnel 8 - in relation to the axial direction of movement of the piston 1 - , but offset thereto. This has the additional effect of ensuring that over one part of the piston stroke the oil is sprayed onto the underside of the piston and over the remaining part of the piston stroke into the collecting funnel 8. <IMAGE>

Patent DE-4335305-A1 (DE)
Title: Method and circuit arrangement for transmitting voice signals
Inventor: LORENZ DIETMAR
IPC: H04L69/40
Filed: 1993-10-16
Abstract: In the transmission of voice data by radio in the European mobile radio telephone system according to the GSM standard, 20 ms voice data are in each case transmitted as source-encoded codewords between the mobile stations and the base stations. The base stations, in turn, are connected via a narrow-band connection to a central station in which the voice decoders are arranged. Since the masking of transmission errors which could not be corrected by the channel decoder takes place in this voice decoder in the central station in the known system, only a very simple error masking capability is provided. According to the invention, more signals which characterise the reliability of the received data are derived from the channel decoder which is arranged directly at the receiver in the mobile stations and base stations, and, in dependence on these additional data, extensive different error masking measures are carried out on the received codewords. This is done not only in the mobile station but also in the base station. This then only supplies already modified codewords, characterised as error-free, to the central station which, as a result, does not need to be modified but in which only the existing simple error masking capabilities are not utilised. When the transmission is disturbed, the voice quality can thus be significantly improved without ... Original abstract incomplete. <IMAGE>

Patent DE-4411815-A1 (DE)
Inventor: GACHECHILADZE IVAN ALEXANDROVI
IPC: G01P5/22
Filed: 1994-04-07
Abstract: The invention concerns a method for the determination of physical composition parameters of a multicomponent and/or multiphase medium, the medium flowing through electromagnetic cavity resonators and the dielectric constants of the medium in the direction of flow and perpendicular to the direction of flow being determined from the frequencies of the natural longitudinal and transverse oscillations of the cavity resonators and, at the same time, the temperature and pressure of the medium measured. The invention also concerns a device for carrying out the method. The invention proposes that the natural frequencies of the resonators are measured in three different spatial directions, thus making it possible to measure the composition and physical nature of any number of phases and components in the medium. In order to increase the measurement accuracy, the invention further proposes that, at each frequency measurement, the resonance frequency and the Q-factor at the resonance frequency are also measured. This gives correction values which are added to the dielectric constants obtained from the resonance frequencies, thus increasing the measurement accuracy by about an order of magnitude.

Title: Control system for controlling the excess air ratio of an internal combustion engine using a generator/motor
Inventor: AOTA HIROYUKI
IPC: B60L50/16
Filed: 1994-08-29
Abstract: A system for controlling an excess air ratio of an internal combustion engine, intended for a motor vehicle, is disclosed, which has a battery, a generator/motor, an air-fuel sensor and a control unit. The generator/motor is mechanically coupled to the internal combustion engine in order to allow a torque transmission between the two and functions both in an engine operating mode and in a generator operating mode. In the engine operating mode the generator/motor serves as motor, which with corresponding power supply from the battery applies a torque of predetermined magnitude to the internal combustion engine. In the generator operating mode the generator/motor functions as a generator in order to convert the engine torque into electrical energy for charging the battery. The air-fuel sensor determines an excess air ratio of the internal combustion engine. The control unit activates the generator/motor in the engine operating mode in order to control the magnitude of the torque to be applied to the internal combustion engine on the basis of the excess air ratio in such a way that the excess air ratio falls into a predetermined range which is suitable for exhaust emission control of the internal combustion engine.

Patent DE-4433550-A1 (DE)
Title: Passenger compartment for motor vehicles with integrated safety device
Inventor: CHANG GIAN HUNG
IPC: B62D39/00
Filed: 1994-09-06
Abstract: The invention relates to a passenger compartment for motor vehicles with integrated safety device, in particular for passenger cars. The invention proposes that springs, preferably helical springs, are arranged in the front, central and rear pillars which bear the roof. The helical springs are preferably to be arranged in the virtually vertical central pillars such that the helical springs produce a force limitation and complete buckling of the pillars is thereby prevented and, furthermore, they effect sufficient lifting of the overturned motor vehicle. Particularly in the case of the front and rear pillars being arranged such that they angle off obliquely towards the passenger compartment, use may also be made, according to the invention, of helical springs with prestressing, on which a spacer, passing through the pillars, is arranged in direct connection with the helical springs. When the roof makes impact with the ground, the locking of the helical spring is released and, due to the prestressing, the spacer arranged in the pillars springs out and thus prevents the top section of the passenger compartment from being completely compressed. It is also within the scope of the invention to arrange the helical springs above the vehicle frame, in the lower part of the passenger compartment. For this purpose, provision is made, above the helical springs, for spacers which, in direct connection with said springs, pass into the pillars. <IMAGE>
