Title: Device for comminuting and grinding brittle material to be ground, such as cement clinker, ore, coal or the like
Inventor: WOLTER ALBRECHT DR
IPC: B02C23/32
Filed: 1987-04-08
Abstract: In order, in the comminution and grinding of brittle material to be ground, with an upstream high-pressure roll press and a downstream tube mill with preliminary separation of the ground material, to be able to use the comparatively low specific total energy requirement without having to carry out costly modification measures on a conventional tube mill which was originally present, it is proposed according to the invention that the tube mill (14) is and remains constructed in a customary manner, that is to say without a rotationally fixedly arranged material fall-out housing, with a central inlet opening (15) through one end wall journal and a central discharge opening (16) through the other end wall journal, and that the discharge (13) of the high-pressure roll press (10) is introduced, through the central tube mill discharge opening (16) and through a central opening (20) in the discharge wall (17), into the material discharge of the tube mill countercurrent to the tube mill discharge material which is guided, together with the de-agglomerated roll press discharge, through peripheral openings of the same discharge wall (17) to the separator (25). <IMAGE>
Patent DE-3713780-A1 (DE)
Title: Arrangement for the attenuation, reduction or compensation of sound waves or noise
Inventor: HORVATH ERNST DIPL ING
IPC: H02K5/24
Filed: 1987-04-24
Abstract: Until now, sound protection hoods or sound-insulation material have been used for noise attenuation. Both types have, however, the disadvantage that a heat build-up has occurred. The use of crystals brought no technically satisfactory solution, since these point-shaped sound sources effected cancellation of the sound only at the intermediate frequency points. It is the object of the invention to reduce or to compensate noise arising preferably in the case of electrical machines or devices. In this case, the sound-emitting body or the housing surrounding the body is enveloped in a film, known per se, made from a polymeric material. A signal of phase opposite to the sound waves is applied to this film, on the side facing away from the body. By means of this invention it is for the first time possible to provide sound-emitting bodies of large surface area with protection against sound or noise.

Title: Sealing device for a drive shaft of a roller-blind-like or shutter-like protective member
Inventor: MATHYS MANFRED
IPC: E06B9/76
Filed: 1987-11-24
Abstract: The through-passage bore (10), penetrated by the drive shaft (9), through structure part (11) is sealed by a sealing body (101) which exhibits, for example, a rigid basic body (102) and a compressible casing (103). Located in the interior of the basic body (102) is a ball socket (106) in which a ball (107) is seated such that it can move. Located in the ball (107) is a four-sided through-passage (108) which matches the four-sided drive shaft (9) which penetrates it. The through-passage bore (10) is thus closed off in a simple, but permanent manner because the movement wear on the parts - ball socket (106) and ball (107) - which can be configured in a correspondingly low-friction manner is reduced. Good heat insulation, good sound insulation and appropriate gas-tightness are obtained. <IMAGE>

Title: Control of pipe advances by means of asymmetrical longitudinal prestressing
Inventor: SCHERLE MAX DIPL ING
IPC: E21D9/06
Filed: 1987-12-19
Abstract: Method for control of pipe advances by means of asymmetrical longitudinal prestressing. The control, customary according to the prior art, of pipe advances by inclining the shield (or cutting shoe) with respect to the following pipes requires, in order to take effect, an adequately high earth resistance. It thus fails in the case of advancing in soils having too low an earth resistance. Since, however, pipe advances are also to be driven in soils having reduced earth resistance, the object arises of pointing out a method which also makes pipe advances controllable in such soils. The new method assumes that pipe sections, the individual pipes of which are connected to one another in a tension-resistant manner and the gradient of which is a circular arc, continue the specified circular arc-shaped gradient in the case of further advancing. In order to produce a circular-arc-shaped gradient of a section, according to the novel method, a selectable number of pipes is prestressed asymmetrically in the longitudinal direction. As a result of the asymmetrical pressing and deformation, effected in the process, of the pressure compensation rings between the pipes and the asymmetrical length change of the pipes, the gradient of the relevant section assumes the form of a circular arc. As a result of the magnitude of the longitudinal prestress and the extent of the asymmetry, the radius of the circular arc of the gradient can be calculated in connection with the deformability of the pressure compensation rings and of the pipes.
