Title: Process for the isolation of alkylsulfamidoalkanecarboxylates or alkylsulfamidoalkanesulfonates from their mixtures with hydrocarbons
Inventor: SCHATZ JOSEF
IPC: C23F11/16
Filed: 1981-03-19
Abstract: Compounds of the formula <IMAGE> are isolated from their mixtures with hydrocarbons as they are obtained in the preparation of the abovementioned compounds. In the above formula, R1 denotes a C8- to C25-alkyl radical, R2 denotes a hydrogen atom or a C1- to C4-alkyl radical, R3 denotes a C1- to C3-alkylene radical, Z<(-)> denotes an anionic radical of the formula -COO<(-)> or -SO3<(-)>, and X<(+)> denotes one of the following cations: Na<(+)>, K<(+)>, <IMAGE> in which R4, R5, R6 and R7 can be identical or different and each of which denotes: H; C1- to C4-alkyl, cyclohexyl or C2- or C3-hydroxyalkyl, all radicals R4 to R7 together not having more than 12 C atoms. One part by weight of the mixture is treated for 0.5 to 20 hours at 20 to 180 DEG C with 0.5 to 5 parts by weight of various glycols or glycerol, and the two phases which then settle are separated. The glycol-containing phase is either used as such, for example, in cooling liquids, or the abovementioned compound is obtained from this phase by evaporation of the volatile components.

Title: Joint between the door and side wall of a piece of furniture
Inventor: MARTI MANUEL BLANCO
IPC: E05D3/06
Filed: 1981-09-10
Abstract: The invention relates to a joint for the pivotable fastening of a door to a piece of furniture, the joint being completely concealed in the closing position of the door and allowing a pivoting movement of the door through 180 DEG . The joint consists of seven parts produced from flat metal and of seven pins which connect the flat-metal parts in an articulated manner.

Title: Device for resetting the steered wheels of a motor vehicle
Inventor: NAUMANN FRITZ DR ING
IPC: B60G15/07
Filed: 1981-09-17
Abstract: The invention relates to a device for resetting the steered wheels of a motor vehicle, with a steering device and wheel suspensions guiding the wheels, in which device at least one spring engages with parts coupled indirectly or directly to the wheels and in the locked state of the wheels loads them in the direction of the position of straight-ahead running. In order to avoid a disadvantageous influence of the resetting forces during the straight-ahead running and an undesired counter-steering, the loading of the springs out of the straight-ahead position is only initiated at a steering angle of greater than 3 DEG , preferably around 10 DEG .

Title: Method for analog/digital conversion and for digital/analog conversion
Inventor: WENDLER KLAUS-PETER DIPL ING
IPC: H03M1/00
Filed: 1981-10-29

Patent DE-3150478-A1 (DE)
Title: Process for producing negative cadmium electrodes for alkaline storage batteries
Inventor: HORN KARL-GEORG DIPL PHYS DR
IPC: H01M4/26
Filed: 1981-12-19
Abstract: Instead of the standard formation, which comprises a cyclic treatment in excess hydroxide solution, freshly produced negative cadmium electrodes for alkaline storage batteries are cleaned and activated by a heat treatment lasting approximately 1/2  hour at approximately 240 DEG C. The process, which can be referred to as "thermal formation", brings about a partial conversion of the poorly conducting Cd(OH)2 into conductive CdO and a decomposition of undesirable impurities such as carbonates, or nitrates entrained from the impregnating process. Ni/Cd cells containing negative electrodes pretreated in this way have a substantially lower self-discharge and good high-current-carrying capacity.

Patent DE-3209737-A1 (DE)
Title: Control circuit for voltage stabilisers
Inventor: HILSCHER LOTHAR DIPL ING
IPC: G05F1/20
Filed: 1982-03-17
Abstract: In the control circuit according to the invention, a particular winding tap (12-1 to 12-30) of a transformer (12) is selected as a function of a nominal/actual value comparison carried out. The actual value and the nominal value are supplied in digital form to a microprocessor (6, 7, 8). Depending on the result of the nominal/actual value comparison, the microprocessor takes from its associated read-only memory (9) an information item which corresponds to a particular setting value for selecting a particular winding tap. A zero crossing detector (13) detects the zero crossings of the load current. After a zero crossing has been detected, the setting value is in each case detected by the microprocessor. After the next zero crossing has been detected, an electronic switch (15-1 to 15-30), which is allocated to the particular winding tap, is triggered after the previously triggered electronic switch, which is allocated to the winding tap previously selected, has been cut off. <IMAGE>

Patent DE-3217147-A1 (DE)
Title: Densimeter for natural gas and other gas mixtures
Inventor: BOEHM JUERGEN DR ING
IPC: G01N9/00
Filed: 1982-05-07
Abstract: The densimeter is provided with a vibrating body, in particular in the form of a tuning fork, which is exposed to the gas and which is composed of a high-alloy steel with a largely temperature-independent modulus of elasticity. The vibrating fork is part of a phase-coupled electromagnetic vibration system and is, on the one hand, excited in one of its natural frequencies and, on the other hand, said natural frequency, which varies with the difference in the density of the gases, is measured. The surface of the vibrating fork is coated with a uniformly thin skin composed of gas-resistant plastic. This avoids the measurement error due to the relatively high affinity of the natural gas for the material of the vibrating fork, i.e. due to the attachment of heavy gas molecules to the surface of the vibrating mass. The gas molecules now only come into contact with the skin of the plastic coating, which has a substantially lower affinity for the gas molecules than the metal surface.

Abstract: The slope-mowing appliance consists of a mounted-on frame connectable to an agricultural working vehicle at the front or at the rear. This frame comprises a main bearer which is connected pivotably about a vertical axis to a mounted-on frame connection part fixed to the tractor and which is supported on the ground by means of a supporting wheel, and a jib which is supported pivotably on the main bearer of the mounted-on frame and which comprises a pivotable inner arm and a likewise pivotable outer arm. A mowing unit is connected pivotably to the free end of the outer arm. At the same time, the end of the main bearer located on the appliance is assigned directly to the pivot axle for the inner arm of the jib, the inner arm is angled in a L-shaped manner and there is a pressure-medium cylinder which is articulated, on the one hand, on the main bearer approximately level with the pivot axle and, on the other hand, on the inner arm in the region of the angling. The jib and the mowing unit are pivotable between the ends of the main bearer, as seen in the direction of travel, into a position of rest in which the long leg of the inner arm assumes a position approximately parallel to the ground underneath the pivot axle, the outer arm assumes a position swung up against the inner arm and above this, and the mowing unit assumes an approximately horizontal alignment with mowing tools pointing towards the ground.

Title: Verfahren zum trennen von suspensionen in einer klaer-filter-zentrifuge sowie klaer-filter-zentrifuge

IPC: B04B7/16
Filed: 1982-10-19
Abstract: Die Abtrennung von schwer filtrierbaren Feststoffteilchen aus Suspensionen erfolgt mittels einer Klär-Filter-Zentrifuge. Die in die Zentrifuge eintretenden Teilchen werden über einen Verteilerkegel (11) derart beschleunigt, daß sie radial an die Kammerrückwand (4) zum Trommelmantel (5) und wieder axial zum Filterteller (8) umgelenkt werden. Weil die Geschwindigkeit der Flüssigkeitsströmung im Trennraum kleiner ist als die Trommelgeschwindigkeit entsteht ein Schlupf. Dadurch können sich die feinen Partikeln am Filtermittel nicht festsetzen und werden immer wieder abgeschält. Die Kammerrückwand (4) ist mit mindestens drei Bolzen (2) an der Kammervorderwand (1) befestigt. Über den Verteilerkegel (11) zur Beschleunigung der eintretenden Suspension ist ein Einlauftrichter (12) gestülpt, dessen Rand parallel zur Kammerrückwand (4) verlängert ist. Das Filtermittel besteht aus einer Membran.
