Title: Waterproof installation apparatus for flush mounting
IPC: H02G3/08
Filed: 1981-02-28
Abstract: The invention relates to a sealing body for electrical installation apparatuses which encloses the respective apparatus, switch, plug socket etc. completely and resting relatively tightly on it. In this case, the sealing body consists of two sealing parts which are of equal size, are located side by side and are connected to one another via elastic strips (rubber bands), and into which mouldings or openings are in each case incorporated which correspond to the respective contour of the electrical apparatus. Once the apparatus has been inserted into the lower sealing part, the upper sealing part is folded over the inserted apparatus. The apparatus is thus completely sheathed and watertight. In addition, such a watertight sheath does not occupy any significant space so that the connection space is essentially maintained when apparatuses are used in commercially-available 55-type flush-mounted sockets.

Title: Process and apparatus for producing groundwater wells and for lowering the groundwater level
Inventor: ESTERS KLAUS DIPL ING
IPC: E02D19/10
Filed: 1981-03-05
Abstract: The invention relates to a process and an apparatus for producing groundwater wells and for lowering the groundwater level. When producing the groundwater well, preferably by means of slush boring, a protective tube (9) is sunk to the lowest groundwater level to be drained, on the lower end of which tube there is located a nozzle device (10) which, after the sinking procedure has finished and on simultaneous installation of the underwater pump unit (11) with the aid of a high-pressure liquid nozzle jet (10) up to 500 bar, preferably a water jet, breaks down, according to grain size, the solid-ground layers (1), adjacent to the protective tube (9), in a wide groundwater coverage range. The fine-grained fraction (2) flushed out by the nozzle jet (10f) is conveyed, in the annular space present between protective tube (9) and bore (7), to the surface, while the remaining coarse-grained fraction, as a porous, annular filter element (3), makes it possible for the groundwater (6) to be sunk to permeate and flow through the adjacent solid ground (1) to a large extent. The flushed-out fine-grained fraction (2) is replaced by the constant addition, which can be checked, of filter gravel (4) into the protective tube (9) from the surface, the filter gravel (4) being received by the filter element (3), with the result that a coarse-grained rock filter, which rests on the underwater pump unit (11) and avoids ground loss, subsidence and cavities in the well area, is maintained. <IMAGE>

Patent DE-3209560-A1 (DE)
Title: Method for determining a leakage point in a pneumatically monitored cable
Inventor: TAEGE RUDOLF
IPC: G01R31/08
Filed: 1982-03-16
Abstract: To determine a leakage point in a pneumatically monitored cable, the cable length is subdivided into individual sections by pneumatic pressure switches (DS) arranged at particular intervals. A measuring wire pair (a, b) provided in the cable is connected by a terminating resistor at the cable end to form a measuring loop, the loop resistance of which is equal to the sum of the individual section resistances (R0) and the terminating resistor (RA). A constant measuring current is continuously fed into the measuring wire loop and the voltage drop across the measuring loop is continuously measured. When a leakage occurs, the nearest pressure switch (DS) operates and bridges the measuring wires at this point. The voltage drop, which then changes, is compared with the previous voltage drop and from its ratio and the total loop resistance, the remaining loop resistance up to the bridging point of the measuring wires, and thus the number of cable sections up to the triggered pressure switch, are calculated. After the leakage point has been located in this manner, change-over switches and a diode circuit are used for disconnecting the triggered pressure switch out of the measuring loop so that it is free for further leakage signalling until the leakage has been eliminated. <IMAGE>

Abstract: The fastening device is used for connecting lightweight curtain wall/cladding panels to the wall of a structure and comprises a wall part, a profile rod connected to the cladding panel and displaceable perpendicularly towards the wall part, and an intermediate element. Known fastening devices of this type give rise to undesired assembly constraints and necessitate a considerable outlay in terms of installation time, fastening parts and connection means. These disadvantages are eliminated by the invention by the wall part and the intermediate element together forming a hinge, having perpendicular, cylindrical contact faces with a large radius of curvature, and by the intermediate element being connected in a frictionally locking manner to the profile bar during assembly. The outline of a fastening device, made of extruded aluminium alloy, as well as the wall dowel, profile bar, cladding panels and connection means are represented in the drawing. This device is used for fastening cladding panels made of asbestos cement, metal, plaster or ceramic on outside masonry or concrete walls. <IMAGE>

Title: Box-type trap for trapping animals without causing them injury
Inventor: BROCKMANN KARL
IPC: A01M23/22
Filed: 1982-07-20
Abstract: The box-type trap which has been developed and tested, and for which a patent has been applied for, is used for trapping wild animals without causing them an injury. In addition, by means of a sensible internal arrangement of the box-type trap, the trapped animal can readily be secured so that it can, for example, be marked, inoculated if necessary, and then set free again. The box-type trap provides the forestry authorities with a facility, inter alia, for the effective control of rabies. The box-type trap can be produced for any species of animal, in any desired size, as a complete structure or to be capable of being dismantled. The materials used can be wood, plastic, metal or similar structural materials. In the box-type trap, the box lid can be held partially open in any desired oblique position by means of a special pincer-like lever mounting. The animal is lured into the box-type trap with the aid of a particular bait. If it takes the bait, all that is needed in order to open the pincer-like mounting - because of the high leverage of the mounting - is a slight tugging at the bait. As a result, the box lid slips down and closes the box-type trap. In general, the dead weight of the lid is sufficient to keep the animal trapped. The lid can, however, also be increased in weight or allowed to latch by snap closure. A movable side part is provided in the box-type trap which can be raised from the outside by two cable pulls. As a result, the animal is secured so that it can be treated appropriately and then set free again. <IMAGE>
