Patent DE-3201646-A1 (DE)
Title: Controllable pulse-compression device for high-voltage compressed-gas switching chambers
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/88
Filed: 1982-01-18
Abstract: In order considerably to reduce the drive energy for SF6 switches with autocompression of the extinguishing gas, the procedure is as follows: initially, two compression spaces which are in general different are produced. Then, when a switch-off occurs in a first compression space, the extinguishing gas is compressed at the same time as the switching-off movement. The magnitude of this first compression is, however, still relatively small. A second compression space does not become involved in the compression of the extinguishing gas until shortly before the minimum extinguishing distance, that is to say delayed in time with respect to the start of the switching movement. At the same time, kinetic energy is transformed into potential energy. This is caused by, for example, longitudinal gaps in the wall of the second compression space. The start of the main compression can be controlled by the length of these gaps. Towards the end of the compression movement in the second compression space, the associated compression piston latches firmly onto the wall of this space. In consequence, the switch drive is relieved of stress from the compression pressure. In one embodiment variation, the controllable gas outlet is implemented by means of an annular gap between the gas outlet tube (3) and the wall of the opening in the base of the compression cylinder (1). <IMAGE>

Title: Zinc alloy for hot-galvanising of steels
Inventor: HAENSEL GUENTHER DIPL ING
IPC: C22C18/00
Filed: 1982-01-30
Abstract: The invention relates to an alloy for hot-galvanising of steels, especially those which contain silicon. Conventional hot-galvanising of individual components of steel takes place at 440-460 DEG C in a zinc bath, to which small quantities of aluminium are added for the purpose of reducing oxidation, as a rule about 0.005% by mass. Steels which do not contain any silicon can be galvanised at these temperatures and with this zinc composition without any problems. The zinc layer thickness is 50-150  mu m. In silicon-containing steels, however, significantly thicker zinc layers are formed. The invention is based on the object of suppressing, or at least reducing, the increased growth of the zinc layer under the same galvanisation conditions, as far as possible, by suitable additions to the zinc. According to the invention, this is effected by an addition of from 0.1 to 1.0% by mass of antimony and 0.015 to 0.025% by mass of aluminium.

Title: Method and circuit arrangement for controlling the impact energy in typewriters or similar machines
Inventor: WEHKING HANS
IPC: B41J9/48
Filed: 1982-08-07
Abstract: In order to achieve satisfactory printing strength when writing on a recording medium with a printing mechanism with an electromagnetically actuable print hammer, the impact energy occurring at the recording medium is compared with a reference impact energy stored for the print character involved in the impact and a deviation possibly determined at the same time is used to correct the current supply to the print hammer magnet. The impact energy occurring is determined by measuring the return time of the print hammer from the impact position into the position of rest at a rear stop, and the comparison takes place with reference return times stored for the different print characters, the period over which current is supplied for the subsequent print character impact being changed, if appropriate, in accordance with the result of the comparison.

Title: Method and device for handling funnels for bulk material
Inventor: SCHNELL ARMIN
IPC: B65G11/16
Filed: 1982-12-20
Abstract: In a method for handling a funnel for bulk material, the surface regions of said funnel which are exposed to the bulk material are protected beforehand by a film-like, detachable protective covering or casing. For this purpose, a device according to the invention for carrying out this method uses a film funnel which is introduced, such as suspended, into the funnel for the bulk material and which can be exchanged rapidly and inexpensively for different batches of the bulk material. Since the film funnel covers all the parts of the funnel for the bulk material, all contaminations are also removed when the film funnel is exchanged. The film funnel preferably consists of an antistatic polyethylene mat so that no static charging results due to the bulk material passing through the filter. On the output side, the film funnel can be connected directly via a connection extension to a container to be filled.

Title: Device for recovering heat
Inventor: SIMON ERNST HELMUT
IPC: F28D21/00
Filed: 1983-02-26
Abstract: The invention relates to a device for recovering heat which is contained in exhaust gases in combustion systems, in particular those of heating installations and/or hot water supply systems in one-family or multifamily residences. The exhaust gas pipe leading from the heating installation to the chimney, or one or more lengths thereof, are constructed as a heat exchanger. The pipe which conducts a heat exchange medium and is surrounded by a housing filled with glass wool is in thermally conductive contact with the exhaust gas pipe constructed as a heat exchanger, or is arranged at a defined distance. The pipe conducting a heat exchange medium is led in a meandering or loop-shaped fashion in the housing, and is connected to the exhaust gas pipe in a metallically conductive fashion, or arranged at a defined distance. In a further embodiment of the invention, the tube conducting a heat exchange medium is led in the housing in a spiral shape around the exhaust gas pipe and is connected to the latter in a metallically conductive fashion, or is likewise arranged at a defined distance. According to a development of the invention, the heat exchanger is inserted in the return system in a hot-water heating system. The cooled water flowing back from the heaters of the conventional hot-water heating system into the heating boiler is thus prewarmed in an advantageous way, so that only a relatively small amount of thermal energy is required from the boiler installation.

Title: Device for testing digital broadband transmission devices
Inventor: EICHER WERNER DIPL PHYS
IPC: H04L1/24
Filed: 1984-06-15
Abstract: The essential function of the data tester consists in determining the quality of a data transmission path. This is done by repeatedly transmitting a check text which is tested in the receiver for errors which have occurred during the transmission. Different transmission frequencies can be tested. The test device offers a decimal display of the bit errors and the number of check text blocks. The invention relates to a device for testing digital broadband transmission channels, in particular for bit rates from 10 to 100 Mbit/s. A check text is repeatedly transmitted via a broadband transmission channel. The transmission errors are counted and displayed. A Johnson counter is used in the clock generator. The transmitter and the receiver have the check text stored in memory chips (EPROMs). The check text is loaded in parallel into a shift register and serially transmitted from there via the broadband channel. The receiver collects bit groups in a shift register with the aid of a synchronisation circuit. The bit groups are compared with the bit pattern stored in the receiving-end memory chip. In full-duplex mode, the basic transmitting-end clock corresponds with the basic receiving-end clock to within at least +/- 40% if the check text is suitably selected. The receiving-end clock is 4-10 times faster than the transmitting-end clock. In a preferred embodiment, the basic clock is 80 MHz, ... Original abstract incomplete.
