Patent DE-4305413-A1 (DE)
Title: Method for recondensing a cold gas
Inventor: BRACHA MICHAEL DIPL ING
IPC: F25J1/02
Filed: 1993-02-22
Abstract: A method is described for recondensing cold gas which has escaped from a storage and/or conduit system (1). The cold gas is warmed in a heat exchanger (3), is compressed in a compressor (4) and is cooled down again in the heat exchanger (3). Then, in a second heat exchanger (5), further cooling is effected by heat exchange with an external refrigerant from a closed refrigeration circuit (7). Only then is the cold gas expanded to the pressure of the storage and/or conduit system (1), for example by means of a restrictor (8), while at the same time being partially condensed. The liquid condensed during expansion is passed back into the storage and/or conduit system (1), the fraction which has remained gaseous (flash gas) is passed, to cool the compressed cold gas, through the heat exchangers (5) and/or (3) and is again compressed (Figure 1). <IMAGE>

Patent DE-4312267-A1 (DE)
Title: Segmented shaft for e.g. waste dump - has joints held open by repeated segment raising by hydraulic jacks, lifting cushions or spindles
Inventor: HAEHNLEN VOLKER
IPC: E02D29/12
Filed: 1993-04-15
Abstract: The joints are held open by repeated vertical raising of the shaft segments. The segments are raised by lifting forces applied by hydraulic jacks (12), lifting cushions (13) or spindles mounted within the shaft. Alternatively, they are applied by pulling forces (15) applied to the inner wall of the shaft segment (2) by external equipment. The segments are raised in succession, starting with the uppermost segment. The segments consist of steel reinforced concrete and the sleeves (11) consist of steel. ADVANTAGE - The design limits the vertical load acting on the shaft foundation to a preset max. value and thus avoids the risk of shaft foundation penetration through the base sealing layer of the dump.
Patent DE-4312374-A1 (DE)
Title: Ventilation and venting device of a vehicle fuel tank
Inventor: ASCHOFF WOLFGANG
IPC: F02M25/08
Filed: 1993-04-17
Abstract: In a ventilation and venting device of a vehicle fuel tank, in which ventilation and venting occur by way of a filter with the tank closed, it is intended to reliably prevent wetting of the filter with liquid fuel and/or fuel from flowing out by way of the filter in all vehicle operating conditions and vehicle positions. It is intended that the device to be used for this purpose be of simple design construction, thereby lending itself to rational manufacture, and that it take up little installation space whilst affording high operating reliability. For this purpose, the filter is connected to the tank solely by way of a space which is situated in an area above the highest possible fuel level in the horizontal stationary position of the vehicle and is separated from the rest of the tank interior by a gas-permeable but liquid-impermeable material which may take the form of a film. The film material may be installed pleated in order to increase the specific surface and be protected by a splash guard against direct fuel splashing.

Title: Brake device for motor vehicles with a hydraulic service brake and an auxiliary brake, activatable as emergency brake
Inventor: FRITZSCHING TORSTEN
IPC: B60T13/52
Filed: 1993-05-12
Abstract: In a brake device for motor vehicles with a hydraulic service brake operatable by way of a brake pedal and an additional auxiliary brake, in which the auxiliary brake can be activated as emergency brake by the brake pedal of the service brake should the service brake fail, it is intended that the auxiliary brake act automatically as emergency brake and at the same time be proportionable in its brake force. It is proposed that the proportioning facility be achieved automatically by way of the service brake pedal. For this purpose, a brake device of this type has the following characteristic features:   (a) The auxiliary brake is already activated in a position of the brake pedal in which the brake pedal still has at least a residual travel up to its limit stop, (b) The residual travel serves as operating travel for application of the auxiliary brake, (c) The brake force of the auxiliary brake is directly proportional to the operating travel covered by the brake pedal after activation of the auxiliary brake.   The auxiliary brake is activated by way of a driver, extendable from the brake pedal, as a function of the service brake pressure actually obtained, whilst at the same time taking the position of the service brake pedal into account.
Patent DE-4317410-A1 (DE)
Title: Arrangement and method for the contactless measurement of workpieces having large diameter differences on machine tools
Inventor: ROTHER THOMAS
IPC: G01B11/08
Filed: 1993-05-18
Abstract: The invention presents an arrangement and a method for contactless measurement of workpieces having large diameter differences on machine tools which are located for the purpose of machining in a wheelset turning machine (wheel lathe). This arrangement can be used both in the initial manufacture of new wheelset tyring and in reconditioning and reprofiling and in the correction of brake discs. The features of the invention are to be found in the direct measurement of diameter, distance, radial eccentricity (runout) and axial eccentricity (runout), which surpasses the measuring range of conventional lasers and is performed with the aid of a movable laser which is fixed in an adjustable laser holder (mount) and accommodated in a plunger. The useful effect consists in that on a measurement section which exceeds the measuring range of the laser, workpiece measurements which are independent of the position of the laser in the machine coordinate system owing to the processing of the laser measured values and the values of the plunger position by the machine control system are carried out with high precision without changing the laser data, e.g. focal length of the optical system or prism setting. In this case, the setting of the laser relative to the machine and plunger axes is guaranteed together with the measurement over the entire working measuring range of the machine. The measuring laser is protected against chips by being arranged in the plunger of the wheelset turning machine.

Title: Audio device in a motor vehicle
Inventor: KRAUS OLIVER DIPL ING
IPC: H04B1/08
Filed: 1993-08-05
Abstract: An audio device in a motor vehicle is described. Said device comprises a loudspeaker and an audio-frequency replay unit, the latter of which in turn comprises means for influencing the audio frequency response and is furthermore equipped with first plug connecting means which mate with second plug connecting means on a vehicle-side supply cable (line, lead) at least for the purpose of the electrical power supply. According to the invention, the first plug connecting means comprise means for detecting vehicle-specific and/or equipment-specific coding of the second plug connecting means. Furthermore, means are provided for positive selection of one of a plurality of frequency responses which are predetermined, are defined such that they are to that extent unchangeable, and have been defined on the basis of a survey of the audio acoustics of all types of vehicle, their equipment and national variants and the loudspeakers which are provided in them. The first and second means mentioned are connected to one another via at least one drive path. The coding can be implemented, for example, by means of or via additional electrical contact elements of a plug connection or by means of suitably formed insulating means in order to prevent contact being made with individual coding contacts, as function of the coding.

Title: Time management method
Inventor: KANEKO MASATOSHI
IPC: G04G15/00
Filed: 1994-10-10
Abstract: A method for time management manages the time which relates to the state of a controlled system. When the time of day and/or the date of the clock (timepiece) circuit is set, there is a respectively separate calculation of a period from the instant at which the state of the control system starts in which the time of day and/or the date is set up to the instant at which the time of day and/or the date is set, and of a period from the instant at which the time of day and/or the date is set up to the instant at which this state ends, and then these periods are added to one another in order in this way to obtain a total time period for this state. Even if the time of day and/or the date of the clock circuit is set while a specific state continues, the exact period can be obtained during which the device runs, as well as the exact period during which the device is stopped.
