Patent DE-3703689-A1 (DE)
Title: Electrical resistance unit for use in a fire damp protection region
Inventor: FRIES WERNER
IPC: H01C1/082
Filed: 1987-02-06
Abstract: Electrical installations are accommodated in a housing, which is encapsulated in a pressure resistant manner, in fire damp protection and explosion protection regions, for example in underground coal mining. If the electrical installation consists, for example, of a control device for an underground railway, then braking resistors are required. Until now, such braking resistors were accommodated in separate encapsulated housings, which were connected to the housing of the main installation via flexible cables. The dedicated housing for the braking resistors was required to be able to dissipate the heat energy occurring. In order to create a design which can be handled easily and saves space, and in the case of which it is possible to dispense with external cable connections between the main installation and the braking resistor units, the invention proposes to couple a heat sink rigidly to the housing of the main installation, in which heat sink commercially available heating cartridges are seated in holes. The electrical cables between the heating cartridges and connections of the main installation pass through a connection, which can be released - if required - only from the interior of the housing, through a wall in the housing. Cooling channels to pass water through are constructed in the heat sink. <IMAGE>

Title: Planet fashion wheel pin which can be inserted into the planet carrier of a planetary mechanism
Inventor: WITTENSTEIN MANFRED DIPL ING
IPC: F16H57/08
Filed: 1987-02-26
Abstract: The intention is that the planet-wheel pin (10) should take up as little space as possible axially when inserted in the planet carrier (2) of a planetary mechanism and should be installed in a simple manner and with extreme precision without the use of complex special tools. For this purpose each of the planet-wheel pins (10) is provided at one end with an opening (11) which lies rotationally symmetrical on the axis of the pin and widens conically outwards, into which opening a headpiece (12) provided with a mating cone can be inserted, thereby widening at least part of the circumference of the planet-wheel pin (10) surrounding the conical region of the opening (11). The planet-wheel pins are, in particular, axially hollow and provided there with a thread into which the conical headpiece (12) can be screwed by means of a threaded stud (14) formed integrally on it. <IMAGE>
Patent DE-3711872-A1 (DE)
Title: Moveable device for determining positional data for electronic data processing systems (digitiser), and method of determining its absolute position
Inventor: TAMMEL CHRISTIAN
IPC: G06F3/0354
Filed: 1987-04-08
Abstract: Known digitisers work on a capacitive or inductive basis, and require a pointing device and an electronic recording board. Their disadvantage is that the recording surface is limited by the size of the board, as well as their production cost and price. The invention represents a digitiser which is simple and cheap to manufacture, and works without a recording board and connecting cable, so that the size of the original document is no longer restricted. The digitiser consists of two position capturing systems, for the X and Y directions respectively (e.g. rolling balls), which are preferably mounted in a straight line, and at a certain distance from one another, together with a sensor to scan the edges of the originals and a pointing device in the same plane, and a few keys. An electronic device determines the absolute position of the pointing device from the pulses of the position capturing systems as the device is rotated and translated, and from the sensor which scans the original, using known mathematical relationships. Digitisation of any original, and universal input device for CAD/CAM/CAE systems, personal computers and home computers.

IPC: B09B1/00
Filed: 1988-12-15
Abstract: A waste dump of a standard dump class is covered with at least one waste layer of a lower dump class having a correspondingly lower hazard potential. Furthermore, at least the outer waste layer is provided with a surface-sealing system. Particularly good encapsulation of hazardous wastes is achieved if the latter are covered with other waste layers where the dump class decreases in an outward direction, so that each waste layer is enclosed by a waste layer which lies on top and is of a lower dump class. In this way, waste dumps having a high hazard potential can be reliably enclosed for a long time and isolated from the environment at less expense than in the past.

Title: Method of covering a mattress core and mattress made according to the method
Inventor: MUMENTHALER FRITZ DIPL ING
IPC: A47C31/00
Filed: 1989-03-17
Abstract: A method of covering a mattress core is described, a covering in each case being applied to the upper side and below the underside of the core, the edges of which coverings are drawn towards one another over the side surfaces of the core and interconnected. According to the invention, the connection of the coverings takes place via separate connection means which are subsequently covered with a side surface covering. As a result, the forces arising during use of the mattress are absorbed well on the one hand and the mattress according to the invention has a perfect appearance on the other hand, in particular because the side surface covering is applied separately from the actual connection means and can consist of correspondingly attractive material.
