Patent DE-3342743-A1 (DE)
Title: Making contact with piezoelectric-acoustic transducers for electro-acoustic capsules
Inventor: EDINGER EGON
IPC: H04R1/06
Filed: 1983-11-25
Abstract: Piezoelectric-acoustic transducers normally have two small connection strips: one small strip makes a pressure contact onto the adhesive-side electrode of the piezoceramic part and the second is soldered onto the other electrode. The invention removes the need for soldering the small connection strip onto the ceramic plate. For this purpose, the force to make contact with the second connection element is derived from a connection element shape (for example a Z-shape) which produces a contact pressure, and the other end of the small connection strip is soldered onto the conductor track of an amplifier unit only if required. <IMAGE>

Title: Serial tetrad addition and subtraction device in BCD 8421 code with negating-complementing circuit
Inventor: MERKLE PAUL
IPC: G06F7/495
Filed: 1984-07-06
Abstract: The object of the invention is a tetrad addition and subtraction device in BCD 8421 code, which has:     - as the main circuit, a dual tetrad subtractor (1) - as the correction circuit, a subtraction circuit (2) to subtract the number 6 - for carrying out subtractive additions, not a 9s-complement circuit, but a 15s-complement circuit (4), because for BCD 8421 coding a normal negating-complementing circuit is a 15s-complement circuit - also for carrying out subtractive additions, a pre-adder circuit (3) to add the number 6. Thus, in this addition and subtraction device, subtractions are carried out normally, and additions by subtractive addition. For subtraction, the B inputs are the minuend inputs, and the A inputs are the subtrahend inputs. For subtraction, in circuit (4), the complement bypass is pre-triggered, and the pre-adder circuit (3) is not pre-triggered. For subtractive addition, in circuit (4), the complementing is pre-triggered, and the pre-adder circuit (3) is pre-triggered. <IMAGE>
Patent DE-3425442-A1 (DE)
Title: Hinged connection part
Inventor: ROEDELBRONN HORST
IPC: F16C11/00
Filed: 1984-07-11
Abstract: The invention relates to a hinged connection part in which there are at least two bearing lugs spaced in the direction of a longitudinal centre line of a hinge pin. Depending on the type of object connected, considerable bending moments occur in the plane of the longitudinal centre line of the hinge pin in a hinged connection part of this kind and these can lead to considerable wear on the bearing. According to the invention, the wear is, on the one hand, reduced by manufacturing the hinged connection part as a forging together with its lugs. On the other hand, the unavoidable tolerance with forgings, which would not permit precise setting of the hinge pin, is eliminated by the use, for at least one of the lugs, of an eccentric bush, by means of which precise setting of the hinge pin can be performed. A particular area of application of a hinged connection part of this kind are the hinge rods of awnings, which due to their length give rise to considerable bending moments, where precisely aligned hinge bearings are important.

Title: Process for preparing potassium nitrate
Inventor: LOEBLICH KARL-RICHARD DR
IPC: C01D9/12
Filed: 1985-07-18
Abstract: A process is described for preparing potassium nitrate by reacting a potassium-containing compound such as syngenite (K2SO4.CaSO4.H2O) with calcium nitrate in an aqueous medium. The syngenite is suspended in recycled mother liquor which has been admixed with a suspension of calcium sulphate hydrate seeding material and, by the addition of calcium nitrate, is converted into calcium sulphate hydrate and potassium nitrate which is absorbed by the reaction solution. The calcium sulphate hydrate is filtered off, and the remaining reaction solution which, per 13 mols K2O contains at least 1 mol CaO, is divided in such a way that boiling down of the one portion results in as much water being removed as had been introduced earlier in excess. In the course of this boil-down, the impurity salts which may have been introduced as contaminants of the starting materials are precipitated and removed. After the boiled-down solution is admixed to the remaining portion of the reaction solution, the mixture is cooled to a temperature of preferably from 270 to 330 DEG K and the potassium nitrate formed is isolated virtually free of impurity salts.
