Title: Distribution box for telecommunications equipment - has cables behind rear panel attached to frame giving access to wiring pins on panel
Inventor: RENNER HERMANN ING GRAD
IPC: H05K7/14
Filed: 1980-03-31
Abstract: The distribution box for telecommunication equipment has a compartment (17) at the rear for a set of vertical multiple core cables (4). The sides of the compartment are formed by vertical angles (1) with channels (3) attached to their inside faces, carrying a board (5) with a large number of wiring tags (11) in sets, projecting from it. Down one vertical channel are openings, allowing the cores (8) of cables to pass through and then bend round towards the tags so that their conductors can be wrapped round the tags. A supporting frame (6) for horizontal partitions (7) can be mounted on the board at the rear, sliding over projecting locating pins, and secured by screws. A front cover (16) can be attached to this frame. There is adequate clearance for insertion of a tool (18) for making the connections at the rear.

Title: Filter of electrically resistant material can be heated - to avoid condensn. or for use as catalyst heater
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D46/00
Filed: 1980-04-25
Abstract: A filter is made from a material which is electrically conducting so that it can be used as a resistance heater. This enables the material to be heated without separate heating devices by connecting the filter to an electrical supply. This enables the filter itself to be heated to prevent the temperature falling below the dew-point or to be used as a heating surface for catalysts.

Title: Current limiter for chopper circuit - compares load current with reference to operation switch controlling one of push=pull transistors
Inventor: IMMLER JOSEF
IPC: H02M7/5387
Filed: 1980-07-10
Abstract: The chopper circuit has at least two pushpull transistors used to convert a dc input voltage into an ac output voltage. The current limiter has an auxiliary voltage generator (4) located in the chopper load circuit. A controllable switching device (10) connects the control input of one of the two transistors to the auxiliary voltage generator. The current measuring device (6) measures the current in the load circuit (90). A comparator (1) compares the measured current with a reference voltage (40) generated by the auxiliary voltage generator. The comparator controls the controllable switch. The auxiliary voltage generator consists of a capacitor (43), a limiting resistor (42) and a diode (41). The advantage of the appts. is that the current limiter is independent of external supply voltages.

Patent DE-3105953-A1 (DE)
Title: Device for wetting pneumatic stowing
Inventor: MASCHINENFABRIK KARL BRIEDEN C
IPC: E21F15/08
Filed: 1981-02-18
Abstract: Pneumatic stowing is carried to the site in a pipe. An activator liquid for wetting is fed to the pneumatic stowing via a wetting pipe projecting into the interior of the pipe. The wetting pipe has a series of casing bores and has a nozzle at its free end projecting into the interior of the pneumatic-stowing pipe. A protective body is arranged in front of the wetting pipe in the flow direction of the pneumatic stowing. The protective body causes swirling of the pneumatic stowing, especially in the core area of the pneumatic-stowing flow. Thus the pneumatic stowing is thoroughly wetted by the activator liquid fed via the wetting pipe.

Title: Arrangement for switching off an electrical load as a function of the switching-on time
Inventor: BAESEL WERNER
IPC: H01H43/30
Filed: 1981-04-03
Abstract: In the case of an arrangement for switching off an electrical load as a function of the switching-on time, having a first temperature-dependent resistor (which has a positive temperature coefficient, can be switched on with the load, limits the load current or switches off in conjunction with the switching element), a second temperature-dependent resistor which has a positive temperature coefficient is thermally coupled to the first temperature-dependent resistor, and the second temperature-dependent resistor is connected in parallel with the load. In consequence, reliable protection of the load against excessively long switching on is ensured, with a slight reduction in the load power.

Title: Device for the three-dimensional reproduction of television images
Inventor: MONTANUS ERIKA
IPC: H04N13/00
Filed: 1982-02-02
Abstract: To achieve a stereoscopic television image impression for all conventional television sets (colour and black/white sets), a polarisation foil is placed in front of the screen, in which the direction of polarisation alternately differs by 90 DEG  in vertical strips of less than 2 mm width. A stereoscopic double image alternatingly produced in strips of equal width provides a uniform spatial image impression when viewed through polarised spectacles with a direction of polarisation differing by 90 DEG  for the two glasses. To ease the problem of compatibility, the television set can contain a switching-on and -off device and an automatic brightness difference circuit for the reproduction or non-reproduction of the stereoscopically displaced part-image strips.

Title: Heat exchanger for operation of a high-pressure steam boiler
Inventor: JACOB KARL-AUGUST ING GRAD
IPC: F28D7/04
Filed: 1982-04-08
Abstract: The invention relates to a heat exchanger for operation of a high-pressure steam boiler, with consumers which are connected to a high-pressure steam boiler and the condensate of which is returned to a condensate container, from which feed water is by means of a feed-water pump supplied to the steam boiler and to which the condensate is supplied before the condensate container, connections, which open in a lid of a container, for a first condensate pipe, a feed-water supply pipe and a feed-water removal pipe, as well as a second condensate pipe, being provided, and a feed-water spiral, which extends over the height of the container, being arranged between the feed-water supply pipe and the feed-water removal pipe, the feed-water supply pipe extending as far as the lowest point of the feed-water spiral and the feed-water removal pipe starting from the highest point of the feed-water spiral and the feed-water spiral being designed at its upper end as an approximately plane flat spiral. In order optimally to utilise the heat content of the condensate flowing to the heat exchanger, a recirculation sheet (18) is provided below the flat spiral (12). As a result of this design of the heat exchanger, there is a forced throughflow of the condensate with mechanical heat circulation. The recirculation sheet (18) can in this connection be plane or concave or convex towards the lid. Advantageously, the recirculation sheet (18) is height-adjustable. The heat exchanger according to the invention is particularly advantageously useable in boiler installations for dry-cleaning operations, laundries or the like. <IMAGE>

Patent DE-3217955-A1 (DE)
Title: Suspended coverings
Inventor: SPAETH RICHARD
IPC: F24J2/34
Filed: 1982-05-13
Abstract: The invention provides for supporting membranes by means of warm air, instead of by means of excess pressure, as has been customary hitherto. In this process, the layers of air located under the membrane can heat up by themselves as a result of the "greenhouse effect" known also in the case of air-inflated structures. The membranes should preferably be manufactured from highly flexible films or skins so as to be able to yield to gusts of wind. Depending on the shape and design, such coverings can be used as rain or wind protection, as an accoustic ceiling, as an awning or as an oversize solar collector. However, the invention appears particularly suited to very short-term uses, such as, for example, fairly large outdoor functions.
