Title: Device for reeling webs of material
Inventor: KOOPMANN DIETER DIPL ING
IPC: B65H19/28
Filed: 1984-05-24
Abstract: The device has a roller head (6), which, to feed the web (1) of material onto the reel shaft (4), has nips (10.3, 11.3) which are arranged essentially vertically above one another and through which the web passes, and is adjustable on a machine frame in an essentially horizontal guide transversely to the reel shaft (4). A pressure head (51) is used to wind the web up on the reel shaft (4), which head (51) is mounted in an adjustment device (57, 64) so as to be pivotable about an axis parallel to the reel shaft (4) and can be brought, via an adjustment path which is at least as long as the radius of the largest reel (2', 2'') to be wound on the reel shaft, so far towards the shaft (4), that its pivoting axis (63) is aligned with the axis of the reel shaft (4) and the pressure head (51) can be pivoted about the reel shaft (4) between an initial position and an end position (51'') which is less than one complete revolution away from the initial position, in the direction of rotation of the reel shaft (4). The pressure head (5) forms in the initial position, together with the reel shaft (4), an upwardly open inlet nip (67), for starting the reeling of the web end. The latter can be pressed radially against the winding shaft (4) and, in the pressed-on state, moves with the reel shaft (4) until the end position is reached. The pressure head (51), which is then released from the reel shaft (4) once again, is returned from the end position into the initial position by means of a return element. <IMAGE>

Title: Method of filling hollow spaces or of producing dams, and device for carrying out the method
Inventor: SCHULTE KLAUS DR
IPC: E21D15/48
Filed: 1984-06-09
Abstract: In underground mining and tunnelling, dams which are impermeable to water are produced by means of handy sacks which are filled with dry mixtures of construction material. The water permeability necessary for wetting the mixtures of construction material transported in the sacks is not achieved until in the face area by making perforations, preferably over both large surfaces, so that the usability of sacks of this type filled with mixtures of construction material is always guaranteed even when stored for prolonged periods underground. By the simultaneous perforation and if need be wetting, sacks of this type can be stacked together and one on top of the other and used virtually in the manner of building blocks. <IMAGE>

Title: Non-return plate valve
Inventor: BRUNNER RUDOLF
IPC: F16K15/02
Filed: 1984-07-19
Abstract: The invention relates to a non-return plate valve, in particular for control spools, with a seat ring which is inserted into a flow passage in front of a cross-sectional constriction and has a valve seat to which a movably mounted valve plate with at least one flow cut-out at the periphery is allocated. The valve plate can be supported against the cross-sectional constriction in the direction of flow and can be placed against the valve seat in the blocking direction. In a known non-return plate valve, the valve plate is fettered to the seat ring with a spring which is anchored to a cross pin. A considerable amount of material and production effort is required. The relatively simple non-return valve consists of many parts. According to the invention, a universal non-return valve of simple construction is created by the valve plate being accommodated unfettered between the seat ring and the cross-sectional constriction and by being able to move freely in all directions. <IMAGE>

Patent DE-3430185-A1 (DE)
Title: Method and device for generating a digital signal
Inventor: BOHEIM GUSTAV DIPL ING
IPC: H03K5/135
Filed: 1984-08-16
Abstract: A circuit which generates a digital signal (S1, S2 or S3) which is cyclic and has accurate timing over a long period of time is needed especially in medical ultrasonics. As a rule, the digital signal changes only at a few times within the cycle time (T). A method is specified in an illustrative embodiment, in which the times within a cycle (T) in which a change in the digital signal is desired are written into a memory section (13a). The desired change in the digital signal is written into another memory section (13b). By means of a time comparison between the time written in and the status of a current clock time counter (21), it is determined whether the output signal (S1, S2, S3) is to be changed. The advantage of the method is that the storage space requirement is much lower than if the associated digital signal value had to be stored for each clock time. <IMAGE>

Title: Hands-free system
Inventor: WEYEL ARMIN
IPC: H04M9/10
Filed: 1985-04-17
Abstract: A hands-free system with a central amplifier arrangement and telephone stations which can be interconnected via it and which in each case have at least one loudspeaker and one microphone is intended to be controlled by the speech amplitudes presented in the two formed speech channels in such a way that, on the one hand, acoustic feedback via the telephone stations is reliably prevented and, on the other hand, a favourable operating response is achieved, the effects of loud local noise, e.g. of the type which may be produced by machine tools in the case of telephone stations installed in workshops or by traffic noise in the case of door telephone stations, being able to be eliminated if necessary. For this purpose, the amplifiers which perform the AF transmission and also the control amplifiers which regulate the former are designed so that they can be adjusted, the speech amplifiers being blocked in the output condition and the control amplifiers being preset to a mean amplification factor. The rectified output voltages of both control channels are then activated in phase opposition via a common component in such a way that the amplification factor of the control amplifier fed with higher amplitudes is increased and that of the speech amplifier of the same channel is emphasised.
