Title: Breaker switch for medium voltage with arc extinction - has wall of extinction chamber which provides one of two facing extinction faces
Inventor: HOLLMANN FRITZ
IPC: H01H33/76
Filed: 1980-11-05
Abstract: The switch has an arc extinction chmber for each switch pole, divided to define a pressure cavity and an expansion chamber. The pressure cavity contains two extinction cheeks which are relatively movable towards one another, with the mobile switch contact passing between them into contact with the fixed switch contact. One of the walls of the housing defining the arc extinction chamber is indented inwards to define one of the extinction cheeks, with the other mobile cheek spring biased towards it, so that they are forced apart by the passage of the mobile switch contact. One edge face of the indented wall section formed one of the two partial dividing walls between the press cavity and the expansion chamber. The switch has a simplified construction with reduced material costs with any loss of efficiency.
Patent DE-3044658-A1 (DE)
Title: Non-interruptable transfer of load to standby power supply - using self-conducting FET as switch for standby source
Inventor: WOLFF HERBERT
IPC: H02J9/06
Filed: 1980-11-27
Abstract: The application is typically to low power sub-circuits in data processing equipment. The circuit gives good utilisation of both the main supply (3) and the standby power source (6), the latter being typically a primary battery cell. The standby supply (6) is connected to the load (9), and to the drain circuit of a self conducting FET (11). A diode (10) in the primary supply prevents the standby source feeding back into the former (3). The FET gate is controlled by a voltage sensor (13) which biases the FET into the off state when there is an adequate primary supply voltage. If this voltage collapses the FET (11) comes into conduction and the standby battery (6) takes over the supply to the load. The voltage sensor (13) typically comprises a zener diode (15) as the threshold device which sets the change over voltage, and a transistor circuit (17,18) connected across the FET. The transistor is conducting when the primary voltage is above the threshold value.

Title: Process and apparatus for oxidising liquids and their solids with a long residence path
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/50
Filed: 1981-02-11
Abstract: During wet desulphurisation of flue gases, CaSO3 and Ca(HSO3)2 are produced in aqueous solution which have to be oxidised to CaSO4 or CaSO4.2H2O. This oxidation is effected by sparging the aqueous solution with air. According to the invention, the oxidation is improved by the air or an air/water mixture being introduced into the oxidation vessel, which contains the aqueous solution, in such a way that they, starting from the bottom of the vessel, are given a spiral motion towards the surface of the vessel. This increases the residence time and improves the oxidation efficiency. This also facilitates the discharge of the gypsum crystals formed from the oxidation vessel. <IMAGE>

Patent DE-3127706-A1 (DE)
Title: Process for generating methanol synthesis gas
Inventor: DIEMER PETER DIPL ING DR
IPC: C01B3/52
Filed: 1981-07-14
Abstract: This process starts from the crude gas of a low-pressure coal gasification plant, which is first subjected to H2S scrubbing at low temperatures. The desulphurised gas is then split into two branch streams, of which one is immediately passed into the upper or middle zone of the CO2 scrubber which is likewise operated at low temperatures. The other branch stream, in contrast, is first subjected to a conversion. The converted gas is then introduced into the bottom part of the CO2 scrubber. The gas stream emerging from the CO2 scrubber, in which the two branch streams are recombined, is supplied to the methanol synthesis without further secondary desulphurisation. The H2S scrubber and the CO2 scrubber are connected in this arrangement by a common scrubbing agent circuit.

Title: Process and device for forming handles on ceramic vessels in the plastic state
Inventor: HOFFMANN HANS-DIETER
IPC: B28B11/02
Filed: 1981-07-22
Abstract: The invention relates to a process and a device for forming handles on ceramic vessels in the plastic state. By contrast with the processes and devices hitherto, in which the handles are first produced separately and then have to be moulded onto the actual ceramic vessels in a complicated further process, a process and a device are proposed here by means of which the handles can be simultaneously produced and joined to the ceramic vessels. For this purpose, essentially a calibrating device is used, which has an individually movable pressing piston (7) and pressing cylinder (4) and, after the moulding on of the handle (13) with the simultaneous further shaping thereof, can be removed again from the wall of the ceramic vessel (3). <IMAGE>

Title: Method and device for folding the edge regions of folding bags
Inventor: STURM BENNO DIPL ING
IPC: B65B7/06
Filed: 1981-09-26
Abstract: The invention relates to a method and a device for folding the edge regions of filled folding bags with a, preferably, rectangular basic outline for the purpose of preparing the folding bags for closure. The invention is based on the object of simplifying such a method, thus also reducing the outlay on construction and manufacture required for the device for carrying out the method. The invention is distinguished in that double fingers and single fingers are lowered against the folding bag to be closed, in such a way that two double fingers reach into the central region of the folding bag and at the same time two single fingers are situated outside the two transverse edges of the folding bag, and that the single fingers then push the transverse edges of the folding bag forwards through the double fingers towards the centre of the folding bag, the double fingers being moved approximately simultaneously towards the outside until the seized transverse edges of the folding bag have been drawn in in the manner of a loop and the folding operation has hence been executed. The device for carrying out the method is distinguished in that the double fingers and single fingers are arranged displaceably in a supporting box which is height-adjustable and can thus be lowered against the folding bag to be folded.

Patent DE-3223981-A1 (DE)
Title: Printed circuit
Inventor: GROENIG WOLFGANG
IPC: H05K3/46
Filed: 1982-06-26
Abstract: In the mechanised soldering of rigid/flexible printed circuit boards, there is a danger that flux penetrates between flexible conductor film and rigid substrate board, where it promotes the corrosion of the conductor and component connections. In the printed circuit according to the invention, this is prevented by applying, between conductor film and substrate board, a solder-bath-resistant layer composed of a bonding agent which is soluble in an organic solvent and which assumes the function of a sealant. The process for producing the proposed printed circuit provides a coating of the finally drilled substrate board which is then pressed together with the finished conductor film under the action of heat as a precise fit. The bonding agent which has penetrated the drilled holes is rinsed out with a solvent.

Title: Apparatus for and method of turning pieces of dough
Inventor: FISCHER GEORG
IPC: B65G65/00
Filed: 1982-07-05
Abstract: With the apparatus for and by the method of turning pieces of dough, the pieces of dough are at the same time transferred from proofing trays to baking sheets. The range of applications is substantially of great advantage when handling by means of proofing carriages or stacking carriages. The proofing trays, loaded with pieces of dough, rest on the various levels of the underlying receiving guides of the proofing or stacking carriage. A stacking carriage loaded with empty baking sheets is pushed into the apparatus, after which the apparatus takes over the empty baking sheets and the empty stacking carriage is removed from the apparatus. Thereafter, the proofing or stacking carriage with loaded proofing trays is likewise pushed into the apparatus. The apparatus takes over the loaded proofing trays, which rest underneath the baking sheets in the apparatus, and the empty carriage is removed from the apparatus. The apparatus turns through 180 DEG , so that the proofing boards rest over the baking sheets and the pieces of dough, turned through 180 DEG , lie with the upper proofing side downwards on the baking sheets. The empty stacking carriage is pushed into the apparatus, takes over the loaded baking sheets and is removed from the apparatus for the baking process. A further empty proofing carriage is pushed into the apparatus, takes over the empty proofing boards and is removed from the apparatus for the steps of the method to be carried out once again.
