Abstract: A cylinder arrangement comprising two cylinders (3 and 4) which are parallel in respect of their axes of rotation (2) is used for consolidating fleece (1) in between them by means of heat and/or solvents. The two cylinders (3 and 4) have on their surfaces individual knobs (7 and 8) which are spaced apart and stand out relative to the actual cylinder surface (9 and 10). The knobs (7) on the one cylinder (3) fit between the knobs on the other cylinder and, in use, reach into the spaces between the knobs (8) on the other cylinder. The upper surfaces (5 and 6) of the knobs (7 and 8) on the cylinders (3 and 4) are close or very close to the smooth surface (9 and 10) of the opposite cylinder between the feet of the knobs thereon. Thus, the respective consolidation points (11) of the fleece (1) are mutually offset in height by the height of the knobs or the distance between the surfaces (9 and 10) of the cylinders (3 and 4).

Title: Double-walled lid with concrete filling
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1988-04-12
Abstract: There are lids for manhole covers made of cast iron with a cast-iron surface with fluting and lids of cast iron with concrete filling. The latter are established in standards. In some cases, a lid with a cast-iron surface is required for various reasons, e.g. for paving surfaces. On account of the greater cast weight, however, this lid is more expensive than a lid of cast iron with concrete filling. The innovation shows a lid of cast iron with a cast-iron surface and at the same time a concrete filling. Apart from a thin cast-iron surface, this lid construction has a cast tub underneath with an opening for placing the concrete filling. This lid combines the advantages of a lid with concrete filling with the advantages of a lid with a cast-iron surface with fluting. Since the portion of cast material is only slightly higher, the price relationship is also positive.
Patent DE-3814555-A1 (DE)
Title: Choke valves for fluidic media
Inventor: DIMTER ERWIN
IPC: F16K5/04
Filed: 1988-04-29
Abstract: The choke valves on the market are designed in such a way that a cone of any length and taper restricts or closes by means of a threaded spindle the cross-section of the bore for the fluidic medium flowing through. A great number of turns are necessary until the control adjustment acts from 0 up to full flow. In particular in machines where a rapid infeed stroke and subsequently an infinitely controllable working stroke is required, which in the control range requires, for example, 5-10% of the full cross-section, conventional control valves are completely unsuitable.   The object of the invention is to design a choke valve with a control adjustment of 360 degrees from the full flow up to the desired control adjustment. According to the invention, a flow bore located in the housing is sealed off by a hollow shaft, the periphery of which has the same bore, coinciding with the flow, and a discharging notch is made in the periphery of the shaft, which notch releases the flow during the rotation of the shaft from the piston up to the desired cross-section.

Title: Method for storing and reproducing video signals
Inventor: WETH GERALD DIPL ING
IPC: H04N19/503
Filed: 1988-09-14
Abstract: A method for storing and reproducing video signals is described, the picture information of which is structured into video frames. As a means for carrying out such a method, a known hybrid coder can be used which codes the video data coming from a video data source either in accordance with the intraframe principle or the interframe principle for reducing the bit rates. So that the hybrid decoder connected between memory and monitor does not need to run at a higher speed than normal during a fast check (fast forward or fast rewind) it is provided to code a prescribed section, which can be recognised again in isolation, of predetermined video frames in accordance with the so-called intraframe principle during the storage. During an accelerated check of the stored picture information, the prescribed sections are read out and only these are decoded and reproduced on the monitor.
Patent DE-3835797-A1 (DE)
Title: Pulse discriminator circuit
Inventor: PAULI GUENTER DIPL ING
IPC: G01R29/027
Filed: 1988-10-20
Abstract: A pulse discriminator circuit is specified which, when pulses are transmitted, transfers useful pulses with the correct duration and reliably suppresses short-time noise pulses. The pulse discriminator circuit comprises a pulse-amplitude-normalising stage (3) and a threshold switch (5) with a switching hysteresis which is defined by an upper and a lower threshold value and is located symmetrically between a predetermined upper level and a predetermined lower level. A resistor (9) connects the output (11) of the amplitude-normalising stage (3) to the input of the threshold switch (5). The output signal of the threshold switch (5) is fed back to the input (7) of the threshold switch (5) via a capacitor (17) which is connected into a positive feedback arm (13). A level clamping circuit (19, 19'), which is connected to the input (7) of the threshold switch (5), prevents the input signal of the threshold switch (5) from exceeding the predetermined upper level or dropping below the predetermined lower level. The pulse discriminator circuit only transmits pulses, the duration of which exceeds a predetermined value. <IMAGE>
