Title: Device for separating the tension member of a pretensioned grouted anchor by forming a predetermined breaking point
IPC: E02D5/76
Filed: 1985-03-01
Abstract: To form a predetermined breaking point by heating, the tension member (1) of a grouted anchor is surrounded by an annular sleeve (6) which is filled with an aluminothermic reaction mixture in which an ignition system (16) which can be triggered electrically is embedded. The annular sleeve (6) consists of an outer tube (7) with in each case an inner tube (10) accommodating an individual element (1') of the tie member (1). The hollow space (15) formed between outer tube (7) and inner tube (10) and filled with an aluminothermic reaction mixture is closed off at the ends by lids (8 and 9) which are arranged at a distance (a and b) from the ends of the outer tube (7). The hollow spaces thus formed and open at the ends are filled by plugs (20, 21) of a refractory, hardening material, e.g. concrete. This prevents the reaction mixture liquefied red-hot from flowing off prematurely when the anchor is tilted. <IMAGE>

Title: Circuit arrangement for shearer-loader for underground operations, equipped with a plurality of drive motors
Inventor: WEBER KARL HEINZ DIPL ING
IPC: H02H7/085
Filed: 1985-03-08
Abstract: The subject of the invention is a circuit arrangement for a shearer-loader 1 which is used in underground mining and is equipped with a plurality of drive motors 7, 8 which each has a current transformer 13 and temperature sensor 12. The current transformers 13 of all the drive motors 7, 8 are each connected directly to a common OR gate 16 via in each case one rectifier 15 and the temperature sensor 12. The said OR gate 16 outputs an output signal when a temperature sensor 12 signal occurs which indicates an unacceptable rise in the winding temperature or when one of the current transformers 13 produces a signal which exceeds the admissible value, which output signal is fed to an electronic trigger 17. The electronic trigger 17 subsequently acts on a relay 18 which is located in the switch-on circuit of the shearer-loader 1 and separates the shearer-loader 1 from the electrical mains 10 via the pilot protection 11 and, as a result, prevents unacceptable increases in the winding temperature but also prevents overloading of individual motors 7, 8. <IMAGE>

Patent DE-3508780-A1 (DE)
Title: Device for obtaining useful energy by utilising the vertical lift of water waves
Inventor: KLEMM WOLF DIPL ING
IPC: F03B13/18
Filed: 1985-03-12
Abstract: The invention relates to a device which by means of its propeller-like turbines arranged horizontally in a radial direction with propeller shafts standing perpendicular to the normal water line, drives, for example, electrical generators by utilising the vertical wave movements of waters and thereby converts the energy acting in the water waves into electrical current. A characteristic of the invention is that, inter alia, the propeller blades automatically adjust to the direction of incident flow of the water in such a way that the propeller rotation always turns in the same direction of rotation both in the case of axially upwards and axially downwards directed incident flow. In the invention this is achieved in that either the propeller is raised and lowered by water which itself does not move, or that water moving in the surface area of the water flows at the fixed-height propeller from above or below, thereby causing it to rotate. Furthermore, it is a feature of the invention that it can be designed both as a fixed and as a floating, unsecured system.

Patent DE-3532296-A1 (DE)
Title: Dumper truck
Inventor: GERGEN OTTMAR
IPC: B60P1/48
Filed: 1985-09-11
Abstract: The patent application is concerned with a dumper truck for picking up and setting down containers, silos, pallets or the like, with two single-component carrying arms which can be pivoted with the aid a pair of hydraulic cylinders. 
<??>According to the invention, there is provision for two shoes which are assigned to the carrying arms to be provided at the rear end of the dumper truck, on the rear side of which shoes the carrying arms are rotatably mounted and at the front side of which shoes a pair of hydraulic cylinders are rotatably mounted, and for the pair of hydraulic cylinders to be coupled, on the other hand, to the free ends of the carrying arms. 
<??>A substantial advantage is that, as a result of concentrating the picking-up/setting-down mechanism exclusively at the end of the dumper truck, no reinforcements are necessary in the front region of the vehicle frame. As a result, a substantially lower unladen weight results than in the case of conventional dumper trucks, which permits a larger useful load. Also, by virtue of the arrangement according to the invention, the picking-up/setting-down mechanism can easily be constructed so as to be removable, as a result of which a vehicle can be used for example as a customary transport means in addition to its function as a dumper truck.

Title: Roof rack for a motor vehicle
Inventor: KRUEGER ECKART DIPL ING
IPC: B60R9/058
Filed: 1986-03-10
Abstract: The invention relates to a roof rack (1), which is composed of a supporting tube (2) which has supporting feet (15) on each side, one supporting foot being fixedly connected to the supporting tube (2) and the other supporting foot (15) being pivotably connected to the supporting tube by means of a knuckle joint (20, 21). The movable supporting foot (15) can be clamped to a vehicle roof by means of a clamp screw (25). According to the invention, the bore in the joint hinge (bush 21) is greater than the diameter of the pivot shaft (22), making a three-dimensional pivot movement of the supporting foot (15) about the pivot shaft (20) possible. This makes it possible in particular to achieve longitudinal adjustment and adaptation to a longitudinal inclination of the vehicle roof during clamping. It also makes it possible for supporting plates (19) and clamping clips (18) to rest flat against the vehicle, which means that no harmful loads are exerted at individual points. In a further development of the invention, the bore in the bush (21) is cone-shaped or double-cone-shaped, the narrowest point of the bore approximately matching the diameter of the pivot shaft (20). <IMAGE>

Title: Refrigerating method for safeguarding and reversible rendering unusable military and private kerosene and diesel fuel and fuel oil storage tanks
Inventor: SCHWARZ FRANZ
IPC: F25D3/10
Filed: 1986-04-30
Abstract: In the case of defence, a fuel dump which has for tactical reasons been evacuated but which is still full can be frozen in order to prevent immediate use by the enemy. From a commercially available highly vacuum-insulated liquid nitrogen tank, the cold N2 at minus 197 degrees C is conveyed into the tank with copper pipes via a non-return valve and a vacuum-insulated storage container. In a round copper-pipe coil, which at the top is mounted on a supported tooth strip made of steel and at the bottom is fixed to the same, the N2 is guided through the entire tank, being evaporated and conducted off gaseously. A spraying line, which is suspended above the tank as well as in the tank above the filling level, can also be used for more rapid freezing, and otherwise is an optimum fire-extinguishing installation. All the mounting takes place through the dome shaft, the cover of which is secured by countersunk shear screws. When the N2 supply is interrupted, the inner container situated in the tank free space can prolong the cooling. An accelerated rethawing with hot air or hot oil can only take place when the thermostat valve, which is open at minus degrees and closed at plus degrees, is opened by hand via a safety lock.
