Patent EP-0417650-A1 (EP)
Inventor: HAENSEL ARNDT
IPC: B66F9/18
Filed: 1990-09-07
Abstract: The working device for laying interlocking stones in entire stone courses consists of a chassis (1) with a tower-like superstructure (4) and a gripper (5) which is mounted vertically movably in the tower (4) via a jib (6). The jib (6) is at the same time connected with its bearing carriage (7/8), via a traction cable (10) and a deflection roller (11), to a counterweight (12) which is guided in a rail (13) and can be clamped rigidly to the latter via a braking system. Moreover, the gripper (5) is provided with a locking mechanism (36-44) which, during lowering of the gripper (5) onto a foundation, in each case alternately locks or unlocks the gripper arm (29) in open position. In order to make the handling of the working device, in particular during lifting of the clamped-in stone courses (14) as well as during setting down on the ground, as simple as possible and to be able moreover to position the stone courses (14) more accurately in their place, the deflection roller (11) is also guided vertically displaceably in the tower (4) and supported on the short arm (47) of an articulated lever (47/48) which is mounted pivotably under the deflection roller (11). <IMAGE>

Abstract: A device for closing and opening a pipe contains a pipe body (1) having a connecting piece (6) which can be closed by means of a plug (24). The arrangement is intended to be constructed in such a manner that by means of its use, on the one hand the pipe can be temporarily closed at its end and, on the other hand, the pipe can be continued at low cost if required. It is proposed that the connecting piece (6) be constructed with the pipe body (1), in particular as an integral moulding. The pipe body (1) can be connected at one end to the pipe and, at the other end, has a base (5) which can be removed to continue the pipe from the pipe body (1). <IMAGE>

Abstract: In a first embodiment this invention relates to a process for preparing a white product which principally contains a bisimide. The process comprises: providing tetrabromophthalic anhydride and a solvent in a reaction vessel; forming, at a temperature within the range of from 140°C to 200°C, a reaction mass by adding a diamine, a diamine salt or a mixture thereof to the solution, the formation of the reaction mass resulting in the production of a bisimide precipitate which becomes a component of the reaction mass; terminating the addition of the diamine when the molar ratio of the tetrabromophthalic anhydride initially present in the solution to the diamine or diamine salt added is substantially stoichiometric; cooking the bisimide precipitate to increase the average sphericity of the particles making up the bisimide pre­cipitate; and recovering from the reaction mass, as the bisimide produce, the cooked precipitate. In a second embodiment the cooking step is optional and the retention of water formed during the diamine or diamine salt addi­tion is featured.

Abstract: The invention relates to surface-coolers and spray-coolers, such as are used underground for example. A driving and supply unit (1) with an air duct (21) draws warm air (2) in and conveys it with a fan (20) to a spray-cooler (30) with spraying nozzles (31) which atomise cooling water. On the floor, the cooling water is delivered in a high-pressure water pipe (7) and is first supplied via a control (9) to an impulse turbine (10) with a reducing gear (15), in order to drive the fan (20). The drive jet (27), which is deflected in the turbine, is caught with a collecting opening (26) and supplied to the spraying nozzles (31) via a cooling water pipe (8). On the way from the collecting opening (26) to the spraying nozzles (31), the pressure in the cooling water is increased, in order to obtain a pressure gradient across the spraying nozzles (31), which ensures their functioning.
