Patent DE-4233997-A1 (DE)
Title: Level-balancing cam for travel and wear compensation, e.g. for pressure-plate clutches, brake systems etc., and pressure-plate clutches with a wear-compensating system (accumulator) with automatic wear compensation
IPC: F16D65/52
Filed: 1992-10-09
Abstract: On the basis of the above statements and after consideration of the fundamental studies of Case A and B, Case A is preferable. Particular mention should be made of the accumulator system and the constancy of the travel for the primary force generator. The level-balancing cams are identical. Case A operates in a clearly defined manner while, in Case B, locking can occur if the spring system does not operate in a completely balanced manner. For this reason, protection is here primarily sought for Case A of the overall arrangement. A novel type of pressure-plate clutch and alternative systems for brakes etc. with wear compensation are thus obtained. The main application P 4231507.7 primarily describes the toggle cam and the underlying principle, while, here, a new wear adjustment system is disclosed, with particular reference to Case A of the description. The principle described in Case A provides a new combination of fully automatic wear adjustment for which a patent is applied for here. This principle can be employed in an appropriate manner in various areas of application and is not limited to clutches and brakes in actual applications. A combination of Case A and the main application P 4231507.7 is possible and its use worthwhile.

Title: 2-Chloro-5-hydroxy:toluene-5-sulphonic acid prepn. - by sulphonation of 2-chloro-5-hydroxy-toluene in an aliphatic chloro:hydrocarbon solvent with relatively small amts. of sulphur tri:oxide
Inventor: SCHUMANN SIEGFRIED DR
IPC: C07C309/42
Filed: 1992-11-16
Abstract: Prepn. of 2-chloro-5-hydroxytoluene-4-sulphonic acid (I) comprises sulphonation of 2-chloro-5-hydroxytoluene (II) in an inert organic solvent with SO3; and (i) the solvent used is a chlorinated aliphatic hydrocarbon in which (I) is insol.; (ii) liq. SO3 and solvent-dissolved (II) are alternatingly fed in at a mol. ratio SO3:(II) of 1.2-2:1 at a low temp. preventing sulphone formation and oxidn.; and (iii) the (I) prod. is sepd. off using suction. USE/ADVANTAGE - (I) is used as an intermediate for 2,6-dichloro-4-nitro-5-hydroxytoluene which is used in the synthesis of photographic colour couplers. High yields of (I) are obtd. in a process which uses a reduced amt. of sulphonation agent (cf the 7 mols. per mol. (II) of H2SO4 used in prior-art) and so produces waste water of reduced salt loading.

Title: Clamping rail for the plate cylinder of a printing machine, in particular sheet-fed offset printing machine
Inventor: DESPOT JANKO
IPC: B41F27/12
Filed: 1993-05-03
Abstract: A clamping rail which has many divisions in the cylinder groove of a plate cylinder is to be developed further in such a way that tightening of the tensioning screws, assigned to the individual clamping-rail sections, to a different extent, especially in the region of adjacent clamping-rail sections, cannot lead to a destructive deformation or to the printing plate splitting.

Title: Circuit arrangement for determining the fundamental frequency from a signal which is not bandwidth-limited and contains harmonics and interference signals, in particular for determining the fundamental voice frequency from a voice and speech signal
Inventor: STUERZEBECHER EKKEHARD DR ING
IPC: G01R23/165
Filed: 1993-05-06
Abstract: An arrangement is known for determining the fundamental voice frequency for triggering the flash tube of a stroboscope, consisting of the series circuit of a low-pass filter FI1 which has a controllable cut-off frequency, an amplifier having automatic gain control GV1, a zero-crossing detector ND1 and an evaluation and control circuit AS, implemented as a microcomputer, the control of the low-pass filter proceeding in 2 phases, a search phase and the actual control phase. Because of the search phase of about 80 ms, proceeding after each voice interruption, the arrangement has disadvantages for speech analyses. According to the invention, it is proposed to connect in parallel with the series circuit, consisting of FI1, GV1 and ND1 (channel 1), a second identical series circuit, consisting of FI2, GV2 and ND2 (channel 2), on the input side, and to feed the outputs of both series circuits to two separate inputs of AS. The controllable low-pass filters FI1 and FI2 obtain different control signals TFS1 and TFS2 via two separate control outputs from AS. As a result, the search and control phases can be carried out in parallel. The invention is applied in speech analysis, in stroboscopes and in voice diagnostics. <IMAGE>

Filed: 1993-11-24
Abstract: The signal generator includes a microcontroller (4), a first non-volatile memory (5) and an adjusting device (6) which interacts with the microcontroller. The microcontroller generates the control signal for programming the tracking synchronisation (2) for each initialisation of the signal generator by use of a control program stored in a second non-volatile memory (7) and an adjustment magnitude stored in the first non-volatile memory for input to the control program. When the adjustment device is operated it passes a value to the microcontroller which calculates the adjustment magnitude from it and stores the magnitude in the first non-volatile memory.

Abstract: The motor-driven nail filing devices which have previously been on the market do not provide adequate protection against injury. The invention is intended to provide complete protection from injury, to be easy to handle for anyone and to guarantee an improved view during operation. In order to guarantee complete protection during operation, the disc file (5) on the fingernail and toenail filing and polishing device is covered on five sides. Only on the sixth side is there an open gap for operation. The protective cover (4) consists of a transparent material and guarantees a view to the operating region. Designed as a magnifying glass, it additionally improves vision. The intermediate plate (3) below the disc file (5) projects and thus serves as a stop for fingers and toes. The invention is provided for filing and polishing fingernails and toenails in professional use and in private use for anyone. <IMAGE>
