Patent DE-3409867-A1 (DE)
Title: Removal nozzle for liquid containers
Inventor: WEIHRAUCH GEORG
IPC: B65D47/06
Filed: 1984-03-17
Abstract: The invention relates to a removal nozzle (1) for liquid containers, such as cleaning bottles and the like. When applying liquids situated in liquid containers of this type, the problem often occurs that, on the one hand, a long removal nozzle (1) is required in order to apply the liquid to the desired site but, on the other hand, the part of the removal nozzle (1) projecting beyond the container is to be as short as possible for various reasons when not in use. Furthermore, it may be necessary for the liquid to be used under various conditions, specifically, but not only, in an axial basic application direction. To solve this problem, in a removal nozzle (1) provided with a retractable central portion (3) constructed in the manner of a bellows, the invention provides for the end piece (4) to be able to be bent to the side relative to the lower part (2) in the extended state of the central piece (3). <IMAGE>

Title: Rearview mirror measuring marks for vehicles of all kinds
Inventor: GRIESEL HEINRICH
IPC: B60R1/02
Filed: 1984-03-26
Abstract: In general, the driver of a motor vehicle is unable to precisely determine or correctly estimate his distance from the following vehicle; this applies particularly to learners. If the inside rearview mirror and/or the outside rearview mirror are in each case provided with two pairs of parallel marking lines at specific distances, every driver, even a learner, can then determine his distance from the following vehicle by comparing the sizes of the mirror profiles between the pairs of marking lines in each case and therefore decide whether he should carry out or not carry out his planned overtaking manoeuvre.

Title: Method for operating a condensation laundry drier
Inventor: ROST KLAUS DIPL ING
IPC: D06F58/24
Filed: 1984-04-02
Abstract: What is described is a method for operating a condensation laundry drier, in which the circulated process air is heated before it enters a drying drum for moisture absorption, and is then cooled in a condensation device for moisture emission by a stream of cooling air. The process-air temperature necessary for the drying operation is first reached in a heating phase, is maintained in a drying phase and is then increased in a superheating phase. After the drying operation has ended, the temperature of the process air is reduced. At least during the heating phase, the stream of cooling air is cut off. The heating time can be reduced by means of this measure, so that the desired drying temperature can be reached more quickly. The heating phase can thus be reduced by up to 50%, with the result that a decrease in the energy consumption of the entire drying process of up to 5% can thereby be obtained.

Title: Control principle for a switched-mode power supply
Inventor: HOEGENER JUERGEN ING GRAD
IPC: H02M3/10
Filed: 1984-12-03
Abstract: The subject-matter of the invention is a control principle for a switched-mode power supply for complete load control. In this case, the control circuit operates using the combination of the two control principles of pulse-width control and multi-cycle control. In the region of normal load operation tw, the control circuit operates on the principle of pulse-width control, while, in the event of the loading being reduced below the minimum load temin for pulse-width control, it changes over in the region tp to the control principle of multi-cycle control tp. In this way, the output voltage UA can be controlled in a stable manner down to no load. <IMAGE>

Patent DE-3446310-A1 (DE)
Title: Storage and retrieval system
Inventor: GRONAU JUERGEN
IPC: B66C7/12
Filed: 1984-12-19
Abstract: The running mechanisms of a monorail vehicle which is guided between a floor rail (11) and a top rail each consist of a single running wheel which runs on the continuous running surface of the floor rail (11). The running wheel is steered by deflection elements (22, 23) which act laterally on the floor rail (11) and are lifted in stages at branching points (25). Each running mechanism has bracing parts (28) which are arranged on both sides and reach under the running surface (111). In front of and behind branching points, the deflecting elements (22) can be disengaged by the bracing parts (28) from the running surface (111) and lifted. To this end, the bracing parts (28) are either pivoted about their vertical axis or are lifted through recesses in the floor rail. The bracing parts (28) prevent the running mechanism (15) from being able to lift from the floor rail (11). <IMAGE>

Title: Apparatus for the extraction of soluble constituents from solids with the aid of liquid solvents
Inventor: EHRHARDT MANFRED DR
IPC: B01D11/02
Filed: 1985-04-06
Abstract: The invention relates to glass equipment for the extraction of soluble constituents from solids with the aid of liquid solvents characterised in that the vessel (described in the accompanying drawing as "extraction casing" and "sorption column") containing the solids to be extracted can be separated by means of ground glass joints from the part of the equipment serving for the distillation of the solvent and in that the solvent recovered from the extract by distillation within the equipment continuously flows through the material to be extracted from bottom to top. After the extraction is completed, the solvent which is situated in the vessel containing the material to be extracted, by opening the flat tap, is either combined with the extract or collected separately for testing the completeness of the extraction. A flat tap is necessary in order to avoid sticking of the tap which is ungreased to avoid contamination of the extract by tap grease.

Title: Circuit arrangement for producing a pulsating magnetic field in the exciter coil of an inductive flowmeter
Inventor: DOLL FRIEDHELM DIPL ING
IPC: G01F1/60
Filed: 1985-04-11
Abstract: The exciter coil (21), which produces a pulsating magnetic field of alternating polarity, is connected via transistors (20, 23) to the two poles (15, 16) of the DC voltage source (10). A diode (19, 22) is connected between each pole (15, 16) and the associated transistor (20, 23). When the polarity of the energising current reverses, in each case one capacitor (33, 34) having a relatively low capacitance is charged via a freewheeling diode (25, 26) to a voltage which is higher than the supply voltage. During the next change in polarity, this capacitor is discharged via the associated transistor, so that the remagnetisation of the exciter coil (21) is accelerated by the excess voltage. By shortening the time for the current to build up in the exciter coil, it is possible to operate with a relatively high pulse repetition frequency, so that the flow meter supplies a higher number of measurements per unit time. <IMAGE>

Title: Drive device for the auxiliary units of internal combustion engines, especially of motor vehicle internal combustion engines
Inventor: KASTNER MICHAEL DIPL ING
IPC: F02B67/04
Filed: 1985-07-05
Abstract: The invention relates to a drive device for the auxiliary units of internal combustion engines, especially of motor vehicle internal combustion engines with a transmission, which is connected by its input to the internal combustion engine and by its output to the auxiliary units, the gear transmission ratio being adjusted as a function of the speed of the internal combustion engine. According to the invention the transmission is constructed as a shift transmission (1) with at least two stages. The individual shift stages are automatically selected in that at higher speeds of the internal combustion engine the transmission ratio of the shift transmission (1) is adjusted so as to reduce the speed on the output. The speed range is thereby reduced and the auxiliary units operated in a correspondingly smaller and optimally definable speed range. As a result the total power input of the auxiliary units is reduced and the auxiliary units can be constructed smaller and lighter since the mechanical load and the wear due to high maximum speeds such as occur with a direct drive of the internal combustion engine no longer occur. The auxiliary units are moreover directly flange mounted on the shift transmission, providing a compact preassembled unit. <IMAGE>

Title: Device for manufacturing in sections a multi-span bridge supporting framework made of reinforced concrete or prestressed concrete
IPC: E01D21/00
Filed: 1985-07-31
Abstract: For manufacturing a multi-span bridge supporting framework made of reinforced concrete or prestressed concrete, use is made of an advance framework (3) consisting of at least one framework support (17) and a platform (10) supporting the form (24, 25, 27) for a superstructure section (1b). The advance framework (3) is supported raisably and lowerably and displaceably in relation to a pier (2b). During the advance of the advance framework (3) to the next section, the respectively last finished superstructure section is supported at its front end by upper sliding bearings (28) and lower sliding bearings (29) which form pairs of mutually assigned sliding bearings for direct support of the superstructure section in relation to the pier (2b). The platform (10) is guided through between the sliding bearings (28, 29) on advance of the advance framework (3). The sliding bearings (28, 29) have hydraulic presses; the presses of the sliding bearings (28, 29), which in each case form a pair, are interconnected in a hydraulically communicating manner. As a result, the platform always remains free of constraints; the bearing load is carried off in a direct manner without causing any constraint stresses in the advance framework. Moreover, the advance framework can be lowered independently of the sliding bearings (28, 29) in order to equip the superstructure section. <IMAGE>
