Patent DE-3413468-A1 (DE)
Title: Damping device
Inventor: SCHMID EBERHARD DR
IPC: G01F23/00
Filed: 1984-04-10
Abstract: A damping device preferably used in level measuring instruments and level converters comprises a spring element and a friction element which is frictionally joined to this spring element, the friction element being displaceable at least by a certain amount with respect to the spring element in the direction of action of the spring force. The spring element is preferably constructed as a tension spring and the friction element as an approximately oval ring which exhibits two straight sections which rest against the turns of the tension spring on the inside. This damping device ensures that the loading on the connected mechanical parts of the measuring instrument remains low and that the measurement value is not falsified, the displaceability of the friction element with respect to the spring element playing a significant role since this prevents a hysteresis of the force determining the measurement. The tension spring advantageously exhibits ears through which the oval ring extends and which thus provide a safeguard in the event of overstretching of the spring or of a fracture of the spring.
Patent DE-3419615-A1 (DE)
Title: Two-compartment milking cup
Inventor: FLOETER SIGISMUND
IPC: A01J5/08
Filed: 1984-05-25
Abstract: The invention relates to a customary two-compartment milking cup having a negative pressure relief valve which is opened by the reduction in negative pressure taking place during the relief cycle in the cup sleeve and then allows air to flow into the suction nozzle, two spreading elements (7, 9), which are located diametrically opposite each other and form a spreading body (14) for the teat rubber (3), being moulded onto the suction nozzle/clamping body (6, 12). In the suction phase, the teat rubber (3) rests against the free ends of the spreading elements (7, 9) and, in the relief phase, gaps arise between the teat rubber (3) and the free ends of the spreading elements. A duct (8, 10) is provided which, at one end, leads to the atmosphere and, at the other end, opens out into the interior (11) of the teat rubber. The innovation is seen in the fact that the negative pressure relief valve is formed by the two spreading elements (7, 9) which interact with each other and at least one of which is resiliently deflectable, and which, on the one hand, are supported on one another when pressurised by the tubular teat rubber (3) and thereby close the valve and, on the other hand, spring apart when the pressure is relieved by the collapsed teat rubber (3) and thereby open the valve (Figure 1). <IMAGE>

Title: Cloth folder with a motor-displaced deflection roller
Inventor: WIENEN WALTER
IPC: B65H45/103
Filed: 1984-09-12
Abstract: In order to improve a cloth folder having a folding carriage which can travel along a folding table and has a bearing for a material web supply roller positioned transversely to the direction of travel, having a feeding roller which is arranged on the folding carriage parallel to the axis of the supply roller, can be driven in accordance with the speed of travel of the folding carriage and determines the feed of a web of material, and having a deflection roller which can be moved by means of a motor from an open position across the feeding roller and into a working position, which deflection roller in the open position bounds, together with the feeding roller, a passage for a hanging-down web of material in a horizontal direction and which in the working position causes the web of material to partially wrap round the feeding roller, the improvement being such that a drive device to move the deflection roller only requires a small space despite the large width of the passage, it is proposed that a first chain drive be provided to move the deflection roller between the open position and the working position and that the passage substantially have a width of approximately 120 mm, corresponding to the distance between the feeding roller and the deflection roller in the open position.
Patent DE-3436751-A1 (DE)
Inventor: SCHAEFER PHILIPP
IPC: C14C11/00
Filed: 1984-10-06
Abstract: A leather, in particular a skiver, has depressions on at least one side and also absorbent, protruding fibres on that side. This side is bonded to a layer (14, 14a) which has been formed from an aqueous polymer dispersion and which fills out the depressions and completely absorbs the protruding fibres of the leather (13). This layer (14, 14a) forms either the entire surface finish or, in a two-layered structure thereof, the inner layer (14a) thereof. In this case, the inner layer (14a) has on top of it an outer layer (14b) which has been formed from an aqueous polymer dispersion or from a liquid polymer solution and which has been provided with a textured surface (16). 
<??>Such a surface finished leather is made by applying to the leather, to form the surface finish (14), an aqueous polymer dispersion in an amount between 150 g/m<2> and 450 g/m<2> in the wet phase, then placing the leather with the surface finished side facing down onto a base (2, 2') having a textured surface, and finally press bonding the leather to the applied polymer dispersion and subjecting it to a vacuum treatment. If the surface finish is to have a two-layer structure, then, before the leather with the aqueous polymer dispersion is placed on the textured surface of the base (2, 2'), the latter has applied to it a further aqueous polymer dispersion or liquid polymer solution, and the leather is placed on top of the base only after this further aqueous polymer dispersion or liquid polymer solution has solidified.

Patent DE-3445169-A1 (DE)
Title: Ultrasound unit with switchable level
Inventor: SCHINDLER REINHARD
IPC: G01S7/52
Filed: 1984-12-11
Abstract: In an ultrasound B scan apparatus, a stepwise second possible adjustment which can be varied in coarse steps is provided on further preset controls (13, 15) in addition to a first, continuous possible adjustment on preset controls (9, 11) for the emission level and the receiver gain. The image data obtained during a first possible adjustment are written into a first image store (31). The image data obtained during a second possible adjustment are written into a second image store (33). The scanning operation can alternate with the first and second adjustment or with the first adjustment and a combination of the first and second adjustment. The second adjustment results in an emission level which is reduced in comparison with the first adjustment and/or a reduced receiver gain. As a result, the structures of highly reflecting interfaces (e.g. air bubbles on coupling points, concrements in organs, etc.) are readily visible. Image data from both image stores (31, 33) can be shown superimposed on a screen (35). <IMAGE>

Patent DE-3504244-A1 (DE)
Title: High-voltage rotary load-interruptor circuit breaker
Inventor: RESSEL WILLI DIPL ING
IPC: H01H33/12
Filed: 1985-02-08
Abstract: The invention relates to a high-voltage rotary load-interruptor circuit breaker for closing and interrupting a high-voltage line under load by means of step-by-step rotation of a switching arm in one and the same rotation direction. The auxiliary contact, which is opened once the main contact has been opened without current, draws an arc over an extinguishing gap, which is designed to be as long as necessary and to which at least one expansion space is connected for rapid dissipation of the hot extinguishing gases. In this way, the formation of cool fresh gas is promoted and the cooling of the arc is intensified until it is extinguished. As a consequence of this measure, particularly good reliability is achieved when switching off currents up to 630 A at 24 kV.

Patent DE-3516750-A1 (DE)
Title: Method and device for winding foil capacitors of predetermined capacitance, with a particularly low scatter of the capacitance values
Inventor: BENZ OTTO
IPC: H01G13/02
Filed: 1985-05-09
Abstract: A capacitor winding (W) is produced by winding metal foils (M1, M2) and dielectric films (D1, D2) which are unwound from supply rolls (V1 to V4). The metal foils are connected to a measurement bridge via contact rollers (K1, K2). Said measurement bridge supplies an output signal (UA) which is proportional to the capacitance deviation. The output signal is differentiated by the differentiating element (CD/RD) and in consequence produces a first correction voltage. A second correction voltage is produced by the change in the output signal (UA) per foil length element being determined via the deflection roller (R), the scanning unit (I), the counter arrangement (Z) and the scanning and memory arrangement (SH). The two correction voltages and the output voltage (UA) are added with the correct mathematical sign in an adder ( epsilon ), and the separating element for the separating devices (T1, T2) is triggered when the sum passes through zero. <IMAGE>

Title: Method and apparatus for acid-polishing glass objects
Inventor: ESCHENBACHER GUENTHER
IPC: C03C15/02
Filed: 1985-07-04
Abstract: Glass objects are polished in a treatment container 1 using an etching liquid. To this end, the glass objects are inserted into a perforated drum 9, which rotates slowly through the bath 36 of etching liquid in the treatment container 1. In this process, the etching liquid is continuously rotated by means of a circulating pump 27 through the treatment container 1 and a storage container 28 for the etching liquid. As a result of this, the glass surfaces are rinsed free of particles adhering to them, so that the number of interruptions of the polishing process for intermediate rinses can be reduced, or intermediate rinses can even be dispensed with entirely. <IMAGE>

Title: Process and apparatus for the filling of packaging containers
Inventor: MORSBACH GUENTER
IPC: B65D71/12
Filed: 1985-10-23
Abstract: To adapt the speed of packagings of a predetermined number of liquid containers (bottles or cans) in a cardboard wrapping to the increased filling speeds of the filling stations of beverage manufacturers (for example, breweries), in a corresponding apparatus partially bonded packaging blanks are removed from a magazine and erected in an erection station, front and rear driving battens and a controlled counterslide then move in up to the packaging, and subsequently, in a filling station, in each case two or more liquid containers supplied by means of conveyor bands are pushed into the packaging by means of successive entry stars, up against the counterslides serving as bearing support, and are held by guide rails. After the desired number of liquid containers has been filled, a close packing of the rows of liquid containers is brought about by means of erection slides. In a subsequent closing station, first rear and thereafter front flaps of the packaging are folded around the liquid containers, and finally the front tabs of the packaging containers are bonded and the filled and closed packages are conveyed away. The packaging blanks are provided, on their upper covering faces or on the lower bottom faces, with folding grooves for forming a widening strip.

Title: Program-controlled dishwasher, washing machine or the like
Inventor: HUETTEMANN WILFRIED DIPL ING
IPC: D06F39/04
Filed: 1985-11-26
Abstract: In the case of a program-controlled dishwasher, washing machine or the like which is provided with an electrical heating device for heating the washing or rinsing fluid, the heating device is connected via switching contacts of a heating switch (which is controlled by the program switching mechanism of the apparatus) in the form of a thermal relay to a supply circuit, and is disconnected therefrom. As a result of the use of a program-controlled thermal relay as the heating switch, premature wear of the relay contacts and seizing of said relay contacts are effectively prevented even in the event of the relay being driven erroneously or in an undesired manner. This is contributed to in particular, by the dedicated disconnection delay which is associated with a thermal relay and prevents the heating device being switched off during on-load operation.

Title: Method for electronic detonation of ammunition, and a device for carrying out the method
Inventor: WAHL GUENTER ING GRAD
IPC: F41A19/58
Filed: 1986-01-18
Abstract: The invention relates to a method for electrical detonation of ammunition, especially of small-arms cartridges (cartridges for handguns and long guns), in the case of which a fuze is connected in a fuze circuit in which the fuze heat is produced by means of an arc discharge via an electrode which interacts with the fuze, as well as an electrical high-voltage fuze device. In the case of a known method, the circuit is closed by mechanically applying the electrode to the fuze in order that the discharge which produces the fuze heat can take place. This is thus linked with considerable mechanical complexity for the application of the electrode, as well as the disadvantage that the electrode is subject to severe wear. According to the invention, this is avoided in that the air in a gap between the electrode and the fuze is ionised by means of an AC voltage pulse, and the fuze circuit is then closed in order to discharge by means of an arc. The fuze device is distinguished by the fact that the electrode is opposite the fuze with an air gap such that it does not touch it, and that a voltage generating circuit is provided, by means of which the air gap lying between the fuze and the electrode can be ionised, as a result of which the high-energy arc discharge can then take place.

Title: Method for asynchronous serial data transmission and arrangement to carry out the method
Inventor: BLAHA VIT DIPL ING
IPC: H04L25/30
Filed: 1986-03-27
Abstract: Method for asynchronous serial data transmission with transmission of signals which in each case contain a control bit, and circuit arrangement to carry out the method. In order to set the parity bit of the signals to be transmitted in each case as a control bit, a device for forming parity bits is controlled signal-by-signal in such a way that the parity bit assumes a pre-defined first logic state in the case of a signal with address information and assumes a second pre-defined logic state in the case of a signal of a different type. The parity bits obtained in this way serve as control bits. The method can be used advantageously in monitoring systems in which a central computer is connected via a serial bus to a plurality of monitoring devices. <IMAGE>
