Title: Method of reducing the energy requirement of an electrolytic cell
Inventor: KAPLIN RONALD B
IPC: C25B9/19
Filed: 1987-02-24
Abstract: A method is provided for reducing the energy requirement of an electrolytic cell having a fixed current-carrying capacity. The method is distinguished by the fact that the cell is reconfigured so that additional cathodes and anodes can be incorporated to reduce the total current density of the cell. In order to be able to incorporate additional anodes, the cathodes are reconfigured so as to acquire a narrower cathode finger structure. This is achieved by reducing the spacing between opposite cathode plates, extending the corrugated reinforcing devices and reducing the diameter of the internal current-conducting copper rods in the cathode finger structure. This modification makes it possible to operate the cell at the original specified current-carrying capacity with a substantially reduced energy requirement and a correspondingly reduced current density.

Patent DE-3727356-A1 (DE)
Inventor: GOEHLE ROLF ING GRAD
IPC: H01H71/10
Filed: 1987-08-17
Abstract: Electrical switchgear for fitment to installation circuit breakers.   Known switchgears have one or more contact points on which a switch mechanism acts, the switch mechanism interacting with an adjacent circuit breaker. Differential operation of the contact points is thus not possible. To operate the switch poles 35, 45, a switch mechanism 36, 46 is provided in each case, which switch mechanisms are independent of one another and in each case have a coupling element which engages with the adjacent circuit breaker. In this case, each switch mechanism 36, 46 operates a switch pole 35, 45 which in each case is designed as a two-way switch. The arrangement permits the optional connection of the switch poles as opening or closing contacts and allows them to be operated differentially.

Title: Apparatus for guiding torch lances, samplers and the like in and/or out through the orifice of a container
Inventor: PUFAL ROLF HANS
IPC: F27D21/00
Filed: 1987-09-03
Abstract: The guidance of lances, samplers, measuring and monitoring members as well as reaction media and the like in and/or out through the orifice in the wall of a container presents great difficulties especially when thermal reactions take place at high temperatures and/or at high overpressures or underpressures in the container. Furthermore, there is the risk that, in this case, either dust-laden and/or toxic reaction gases will escape outwards into the atmosphere or else, in a reaction container working under underpressure, air will pass into the container and have an adverse effect on the course of the reaction in it. According to the invention, however, these disadvantages and difficulties are eliminated by connecting to the orifice (3) in the wall of the container (2) or of the gas-outlet pipe (1) a pipe connection (7) which is provided in the upper region with at least one shut-off member (8) and which is connected laterally to feed and discharge lines (13, 14, 18, 20) for gaseous media. <IMAGE>

Patent DE-3736262-A1 (DE)
Inventor: SCHIECHE JOST
IPC: F41A27/18
Filed: 1987-10-27
Abstract: Two drive motors (2, 3) are connected via a common gear to two output pinions (4, 5) engaging into the toothed ring of the turret. The common gear is composed of two planetary gears (6, 7) which are so connected in series that the web (6.4) of the first planetary gear (6) is connected via a shift coupling (10) to the sun wheel (7.1) of the second planetary gear (7). The first drive motor (2) drives the sun wheel (6.1) and the second drive motor (3) drives the hollow wheel (6.3) of the first planetary gear (6). The first output pinion (4) is connected to the hollow wheel (7.3) and the second output pinion (5) is connected to the web (7.4) of the second planetary gear (7). The interposition of further gearwheel mechanisms (8.1-8.2, 9, 11.1-11.2, 12) ensures that the reduction ratio from the first drive motor (2) to the first output pinion (4) is equal to the reduction ratio from the second drive motor (3) to the second output pinion (5). The first planetary gear (6) acts as a summing gear for the two drive motors (2, 3) and the second planetary gear (7) acts as a differential gear for the two output pinions (4, 5). In this way, tolerance-related irregularities in drive and output are compensated and work can be carried out with very little play in the rotary connection. <IMAGE>

Title: Self-securing screw
Inventor: KAISER MANFRED
IPC: F16B39/28
Filed: 1987-12-11
Abstract: The intention is to provide a screw which can rotate easily in one direction, but cannot be rotated in the other direction, at least not when a tool is attached on the screw head (16). The screw according to the invention comprises two parts (3, 4). The two parts (3, 4) can be fitted together to form a screw with a circular-cylindrical outer surface (1), said two parts coming into contact with one another at at least three points (5, 6; two can be seen in the Figure). In this arrangement, one point (6) has to lie in the vicinity of the outer surface (1). From the other two points (5), which lie one behind the other in the axial direction, a gap (9) extends to the outer surface (1). Consequently, the two parts (3, 4) can be tilted with respect to one another, thus enlarging the external diameter of the screw. Suitable arrangement of the points of contact (5, 6) results in the screw being rotatable in only one direction. <IMAGE>

Title: Control process for a laundry dryer working on the drum principle
Inventor: ECKERT HOLGER ING GRAD
IPC: D06F58/34
Filed: 1988-07-21
Abstract: The drum of a laundry dryer is to be controlled in respect of the reversing rate and the rotational speed in dependence on the laundry type, laundry quantity and laundry case. Known laundry dryers are controlled via permanently predetermined programmes or via drying-time switches. The control process according to the invention allows shorter drying times and higher overall efficiencies. Drying takes place with extreme care of the fabric and the drying results are highly uniform. The loading quantity is recorded electrically by the trend of the motor current in dependence on the change in rotational speed of the drum. When a predetermined current value is exceeded, there is a change-over to reversing mode. This right/left running continues until the time dependence of the current curve is the same both for the right and for the left running of the drum. The control process can be used both for domestic laundry dryers operating on the waste-air principle and in those working on the condensation principle.
