Patent DE-3823574-C1 (DE)
Title: Drive for a transmission with a motor having a reversible rotation direction
IPC: H01H3/26
Filed: 1988-07-12
Granted: 1989-11-16
Abstract: Two small reversing switches (11, 12), which switch when de-energised (which switch to de-energise) and upstream of which a power contactor (13) is provided which has the required switching capacity are provided in order to fix the rotation direction of the drive motor (19). In order to develop this idea, a circuit has been created in which the power contactor (13) alternatively operates a plurality of drive motors. An interlock circuit ensures that only one drive can be connected simultaneously in each case. The drive device according to the invention can be used particularly well for the isolating and earthing switches of switching installations, or parts of them. The invention is furthermore suitable for use in the context of a modern, electronic mains cabling system in which printed circuit board components having a low switching capacity can be used as reversing switches (11, 12). The assignment of one power contactor (13) to a series (row) of outlet panels is likewise possible in the case of the drive according to the invention, for example to form a double-busbar panel with two isolating switches and one earthing switch, or to form a coupling panel. <IMAGE>

Title: Process for forming an alloy compact, and alloy compact
IPC: C21C7/00
Filed: 1989-02-21
Granted: 1990-06-28
Abstract: A process for forming an alloy compact (briquette) for treating iron and steel melts involves introducing a mixture containing at least alloy components such as, e.g., FeSi or SiC and a binder, e.g. cement, into a mould and, by applying pressure, pressing it to give an alloy compact. So as to make its edges, especially at the borders of the top sides and/or bottom sides, more resistant to external stresses, there is pressed into the top side and/or bottom side (2, 3) at least one recess (10, 11) which displaces sideways, at least in part, the material of the mixture and which is at a distance from the borders of the respective top side and bottom side (2, 3) of the alloy compact (1). <IMAGE>

Title: Process for upstream denitrification in waste water pond systems
Inventor: WERNER JUERGEN DIPL ING
IPC: C02F3/28
Filed: 1994-03-18
Granted: 1995-04-13
Abstract: The specific removal of nitrogen by denitrification has only be carried out occasionally and with low efficiency in the case of waste water pond systems, since with the return of the oxygen carrier, no optimisation of the environmental conditions for denitrification proceeded. By means of the novel process, an optimisation of these conditions is achieved as a result of which an increase of the denitrification throughput is to occur. In order to enable combination of feed water and return water in proportion to volume and influx, both influx and return are each run into a retention holder (1 and 2). Both holders end in a shaft (3) having separate siphon chambers for the influx (4) and the return (5). The discharge of both charges is initiated by a double siphon depending on the feed water level. The combination in proportion to volume and time of the required volume of influx water and return water in the mixing chamber (6) and the consumption of the residual dissolved oxygen in the retention holder of the return leads to optimisation of the denitrification conditions. Increase of the efficiency of the specific denitrification in small waste water pond systems. <IMAGE>

Title: Reusable recessing device for making holes in cast surfaces
Inventor: WEBER WALTER
IPC: E04G15/06
Filed: 1994-08-29
Granted: 1996-01-18
Abstract: The two recess mould parts (A,B) each have a semicircular arm and a straight arm pointing on one side towards the curve' centre. They are placed together with their straight arms in each other so that a circular recess is formed. Once the cast is made the mould parts can be moved relative to each other and then removed by driving in a wedge between the opposing straight arms. The mould parts can be spaced from each other by about 2 cm by shortening the curved arm length. Two plates (D), also slightly curved if required, are used to cover the gaps so that no material can enter the recess.
